[0186] Various physical layer modulation and transmission mechanisms may be used to implement exemplary embodiments of the present disclosure. Exemplary transmission mechanisms may include, but are not limited to, code division multiple access (CDMA), orthogonal frequency division multiple access (OFDMA), time division multiple access (TDMA), wavelet technology, etc. Hybrid transmission mechanisms such as TDMA / CDMA and OFDM / CDMA may also be employed. Various modulation schemes may be applied to signal transmission in the physical layer. Examples of modulation schemes include, but are not limited to, phase, amplitude, code, combinations of these, etc. Exemplary radio transmission methods may implement quadrature amplitude modulation (QAM) using binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 16-QAM, 64-QAM, 256-QAM, etc. Physical radio transmission may be enhanced by dynamically or semi-dynamically changing the modulation and coding schemes according to transmission requirements and radio conditions.

[0187] Figure 1 is an exemplary radio access network (RAN) architecture according to aspects of an embodiment of the present disclosure. As shown in this example, the RAN node can be a next generation node B (gNB) (e.g., 120A, 120B) that provides a new radio (NR) user plane and control plane protocol termination to a first wireless device (e.g., 110A). In an example, the RAN node can be a next generation evolved node B (ng-eNB) (e.g., 124A, 124B) that provides an evolved UMTS terrestrial radio access (E-UTRA) user plane and control plane protocol termination to a second wireless device (e.g., 110B). The first wireless device can communicate with the gNB via a Uu interface. The second wireless device can communicate with the ng-eNB via a Uu interface. In the present disclosure, wireless devices 110A and 110B are structurally similar to wireless device 110. Base stations 120A and / or 120B can be structurally similar to base station 120. The base station 120 may include at least one of a gNB (e.g., 122A and / or 122B), an ng-eNB (e.g., 124A and / or 124B), and the like.

[0188] The gNB or ng-eNB may host functions such as: radio resource management and scheduling, IP header compression, encryption and integrity protection of data, selection of the access and mobility management function (AMF) at which the user equipment (UE) attaches, routing of user plane and control plane data, connection setup and release, scheduling and transmission of paging messages (originating from the AMF), scheduling and transmission of system broadcast information (originating from the AMF or operations and maintenance (O&M)), measurements and measurement report configuration, transport layer packet marking in uplink, session management, network slice support, Quality of Service (QoS) flow management and mapping to data radio bearers, support for UEs in RRC_INACTIVE state, distribution functions for non-access stratum (NAS) messages, RAN sharing, and dual connectivity or tight interworking between NR and E-UTRA.

[0189] In an instance, one or more gNBs and / or one or more ng-eNBs may be interconnected to each other via an Xn interface. A gNB or ng-eNB may be connected to a 5G core network (5GC) via an NG interface. In an instance, a 5GC may include one or more AMF / User Planning Function (UPF) functions (e.g., 130A or 130B). A gNB or ng-eNB may be connected to the UPF via an NG user plane (NG-U) interface. The NG-U interface may provide delivery of user plane protocol data units (PDUs) (e.g., non-guaranteed delivery) between a RAN node and the UPF. A gNB or ng-eNB may be connected to the AMF via an NG control plane (NG-C) interface. The NG-C interface may provide, for example, NG interface management, UE context management, UE mobility management, transmission of NAS messages, paging, PDU session management, configuration delivery and / or warning message transmission, combinations thereof, and the like.

[0190] In an instance, the UPF may host functions such as an anchor point for intra / inter-radio access technology (RAT) mobility (when applicable), an external PDU session point for interconnection to a data network, packet routing and forwarding, user plane portion of packet inspection and policy rule enforcement, service usage reporting, an uplink classifier to support routing of service flows to the data network, a branch point to support multi-host PDU sessions, QoS processing for the user plane (e.g., packet filtering, gating), uplink (UL) / downlink (DL) rate enforcement, uplink service verification (e.g., service data flow (SDF) to QoS flow mapping), downlink packet buffering and / or downlink data notification triggering.

[0191] In an instance, the AMF may host functions such as NAS signaling termination, NAS signaling security, access layer (AS) security control, inter-core network (CN) node signaling for mobility between 3rd Generation Partnership Project (3GPP) access networks, idle mode UE reachability (e.g., control and execution of paging retransmissions), registration area management, support for intra-system and inter-system mobility, access authentication, access authorization including roaming rights check, mobility management control (subscription and policy), support for network slicing and / or session management function (SMF) selection, etc.

[0192] Figure 2Ais an exemplary user plane protocol stack, in which service data adaptation protocol (SDAP) (e.g., 211 and 221), packet data convergence protocol (PDCP) (e.g., 212 and 222), radio link control (RLC) (e.g., 213 and 223), and medium access control (MAC) (e.g., 214 and 224) sublayers and physical (PHY) (e.g., 215 and 225) layers may be terminated in a wireless device (e.g., 110) and a gNB (e.g., 120) on the network side. In an example, the PHY layer provides transport services to higher layers (e.g., MAC, RRC, etc.). In an example, the services and functions of the MAC sublayer may include mapping between logical channels and transport channels, multiplexing of MAC service data units (SDUs) belonging to one or different logical channels into / demultiplexing of transport blocks (TBs) delivered to / from the PHY layer, scheduling information reporting, error correction through hybrid automatic repeat request (HARQ) (e.g., one HARQ entity per carrier in the case of carrier aggregation (CA)), priority handling between UEs through dynamic scheduling, priority handling between logical channels of a UE through logical channel prioritization and / or padding. The MAC entity may support one or more parameter sets and / or transmission timings. In an example, mapping restrictions in logical channel prioritization may control which parameter set and / or transmission timing a logical channel may use. In an example, the RLC sublayer may support transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM) transmission modes. The RLC configuration may be based on each logical channel, independent of the parameter set and / or transmission time interval (TTI) duration. In an instance, the automatic repeat request (ARQ) can operate on any parameter set and / or TTI duration configured for the logical channel. In an instance, the services and functions of the PDCP layer for the user plane may include sequence numbering, header compression and decompression, delivery, reordering and duplication detection of user data, PDCP PDU routing (e.g., in the case of split bearers), retransmission, encryption, decryption and integrity protection of PDCP SDUs, PDCP SDU discard, PDCP reconstruction and data recovery of RLC AM, and / or duplication of PDCP PDUs. In an instance, the services and functions of SDAP may include mapping between QoS flows and data radio bearers. In an instance, the services and functions of SDAP may include mapping quality of service indicators (QFIs) in DL and UL packets. In an instance, the protocol entities of SDAP may be configured for individual PDU sessions.

[0193] Figure 2Bis an exemplary control plane protocol stack, in which PDCP (e.g., 233 and 242), RLC (e.g., 234 and 243) and MAC (e.g., 235 and 244) sublayers and PHY (e.g., 236 and 245) layers can be terminated in the wireless device (e.g., 110) and the gNB (e.g., 120) on the network side and perform the above services and functions. In an example, RRC (e.g., 232 and 241) can be terminated in the wireless device and the gNB on the network side. In an example, the services and functions of RRC may include: broadcasting of system information related to AS and NAS, paging initiated by 5GC or RAN, establishment, maintenance and release of RRC connection between UE and RAN, security functions including key management, establishment, configuration, maintenance and release of signaling radio bearers (SRBs) and data radio bearers (DRBs), mobility functions, QoS management functions, UE measurement reporting and control of reporting, detection of radio link failure and recovery of radio link failure, and / or delivery of NAS messages from UE to NAS / from NAS to UE. In an instance, the NAS control protocol (e.g., 231, 251) can be terminated in the wireless device and the AMF (e.g., 130) on the network side, and can perform functions such as authentication, mobility management between the UE and the AMF for 3GPP access and non-3GPP access, and session management between the UE and the SMF for 3GPP access and non-3GPP access.

[0194] In an example, a base station may configure a plurality of logical channels for a wireless device. A logical channel in the plurality of logical channels may correspond to a radio bearer, and the radio bearer may be associated with a QoS requirement. In an example, the base station may configure a logical channel to be mapped to one or more TTIs / parameter sets in a plurality of TTIs / parameter sets. The wireless device may receive downlink control information (DCI) indicating an uplink grant via a physical downlink control channel (PDCCH). In an example, the uplink grant may be for a first TTI / parameter set and may indicate an uplink resource for transmission of a transport block. The base station may configure each of the plurality of logical channels, wherein one or more parameters will be used by a logical channel prioritization procedure at a MAC layer of the wireless device. The one or more parameters may include a priority, a prioritized bit rate, and the like. A logical channel in the plurality of logical channels may correspond to one or more buffers including data associated with the logical channel. The logical channel prioritization procedure may allocate uplink resources to one or more first logical channels and / or one or more MAC control elements (CEs) in the plurality of logical channels. One or more first logical channels may be mapped to a first TTI / parameter set. The MAC layer at the wireless device may multiplex one or more MAC CEs and / or one or more MAC SDUs (e.g., logical channels) in a MAC PDU (e.g., a transport block). In an example, the MAC PDU may include a MAC header, which includes multiple MAC subheaders. A MAC subheader in the multiple MAC subheaders may correspond to a MAC CE or MAC SUD (logical channel) in one or more MAC CEs and / or one or more MAC SDUs. In an example, a MAC CE or a logical channel may be configured with a logical channel identifier (LCID). In an example, the LCID for a logical channel or MAC CE may be fixed / preconfigured. In an example, the LCID for a logical channel or MAC CE may be configured for the wireless device by the base station. The MAC subheader corresponding to the MAC CE or MAC SDU may include an LCID associated with the MAC CE or MAC SDU.

[0195] In an example, a base station may activate and / or deactivate and / or affect one or more processes at a wireless device (e.g., setting values ​​of one or more parameters of one or more processes or starting and / or stopping one or more timers of one or more processes) by using one or more MAC commands. The one or more MAC commands may include one or more MAC control elements. In an example, the one or more processes may include activation and / or deactivation of PDCP packet duplication for one or more radio bearers. The base station may transmit a MAC CE including one or more fields, the values ​​of the fields indicating activation and / or deactivation of PDCP duplication for one or more radio bearers. In an example, the one or more processes may include channel state information (CSI) transmission on one or more cells. The base station may transmit one or more MAC CEs indicating activation and / or deactivation of CSI transmission on the one or more cells. In an example, the one or more processes may include activation or deactivation of one or more secondary cells. In an example, the base station may transmit a MAC CE indicating activation or deactivation of one or more secondary cells. In an example, the base station may transmit one or more MAC CEs indicating starting and / or stopping one or more discontinuous reception (DRX) timers at the wireless device. In an example, the base station may transmit one or more MAC CEs indicating one or more timing advance values ​​for one or more timing advance groups (TAGs).

[0196] Figure 3 1 is a block diagram of a base station (base station 1, 120A and base station 2, 120B) and a wireless device 110. The wireless device may be referred to as a UE. The base station may be referred to as a NB, an eNB, a gNB, and / or an ng-eNB. In an example, the wireless device and / or the base station may act as a relay node. Base station 1, 120A may include at least one communication interface 320A (e.g., a wireless modem, an antenna, a wired modem, etc.), at least one processor 321A, and at least one set of program code instructions 323A, which are stored in a non-transitory memory 322A and can be executed by at least one processor 321A. Base station 2, 120B may include at least one communication interface 320B, at least one processor 321B, and at least one set of program code instructions 323B, which are stored in a non-transitory memory 322B and can be executed by at least one processor 321B.

[0197] A base station may include many sectors, for example: 1, 2, 3, 4 or 6 sectors. A base station may include many cells, for example, ranging from 1 to 50 cells or more. Cells may be classified, for example, as primary cells or secondary cells. A serving cell may provide NAS (non-access layer) mobility information (e.g., tracking area identifier (TAI)) during radio resource control (RRC) connection establishment / reconstruction / switching. A serving cell may provide security input during RRC connection reconstruction / switching. This cell may be referred to as a primary cell (PCell). In the downlink, the carrier corresponding to the PCell may be a DL primary component carrier (PCC), and in the uplink, the carrier may be a UL PCC. Depending on the wireless device capabilities, a secondary cell (SCell) may be configured to form a serving cell set together with the PCell. In the downlink, the carrier corresponding to the SCell may be a downlink secondary component carrier (DL SCC), and in the uplink, the carrier may be an uplink secondary component carrier (UL SCC). The SCell may or may not have an uplink carrier.

[0198] A physical cell ID and a cell index may be assigned to a cell including a downlink carrier and an optional uplink carrier. A carrier (downlink or uplink) may belong to a cell. A cell ID or a cell index may also identify a downlink carrier or an uplink carrier of a cell (depending on the context in which it is used). In the present disclosure, a cell ID may refer to a carrier ID equivalently, and a cell index may be referred to as a carrier index. In an embodiment, a physical cell ID or a cell index may be assigned to a cell. A synchronization signal transmitted on a downlink carrier may be used to determine the cell ID. An RRC message may be used to determine the cell index. For example, when the present disclosure relates to a first physical cell ID of a first downlink carrier, the present disclosure may mean that the first physical cell ID is used for a cell including a first downlink carrier. The same concept may be applied, for example, to carrier activation. When the present disclosure indicates that a first carrier is activated, the present specification may also mean activating a cell including the first carrier.

[0199] The base station may transmit one or more messages (e.g., RRC messages) including a plurality of configuration parameters for one or more cells to the wireless device. The one or more cells may include at least one primary cell and at least one secondary cell. In an example, the RRC message may be broadcast or unicast to the wireless device. In an example, the configuration parameters may include common parameters and dedicated parameters.

[0200] The services and / or functions of the RRC sublayer may include at least one of the following: broadcasting system information related to AS and NAS; paging initiated by 5GC and / or NG-RAN; establishment, maintenance and / or release of an RRC connection between a wireless device and NG-RAN, which may include at least one of the addition, modification and release of carrier aggregation; or the addition, modification and / or release of dual connectivity in NR or between E-UTRA and NR. The services and / or functions of the RRC sublayer may further include at least one of the security functions of the following: key management; establishment, configuration, maintenance and / or release of signaling radio bearers (SRBs) and / or data radio bearers (DRBs); mobility functions, which may include at least one of handover (e.g., intra-NR mobility or inter-RAT mobility) and context transfer; or wireless device cell selection and reselection and control of cell selection and reselection. The services and / or functions of the RRC sub-device may further include at least one of the following: QoS management functions; wireless device measurement configuration / reporting; detection of radio link failure and / or recovery of radio link failure; or delivery of NAS messages from the wireless device to a core network entity (e.g., AMF, Mobility Management Entity (MME)) / from a core network entity to the wireless device.

[0201] The RRC sublayer may support the RRC_Idle state, RRC_Inactive state, and / or RRC_Connected state of the wireless device. In the RRC_Idle state, the wireless device may perform at least one of the following: public land mobile network (PLMN) selection; receiving broadcast system information; cell selection / reselection; monitoring / receiving paging of mobile terminated data initiated by 5GC; paging of mobile terminated data area managed by 5GC; or DRX for CN paging configured via NAS. In the RRC_Inactive state, the wireless device may perform at least one of the following: receiving broadcast system information; cell selection / reselection; monitoring / receiving RAN / CN paging initiated by NG-RAN / 5GC; RAN-based notification area (RNA) managed by NG-RAN; or DRX for RAN / CN paging configured by NG-RAN / NAS. In the RRC_Idle state of the wireless device, the base station (e.g., NG-RAN) may maintain a 5GC-NG-RAN connection (both C / U planes) for the wireless device; and / or store a UE AS context for the wireless device. In the RRC_Connected state of the wireless device, the base station (e.g., NG-RAN) may perform at least one of the following: establishing a 5GC-NG-RAN connection (both C / U planes) for the wireless device; storing a UE AS context for the wireless device; transmitting / receiving unicast data to / from the wireless device; or network-controlled mobility based on measurement results received from the wireless device. In the RRC_Connected state of the wireless device, the NG-RAN may know the cell to which the wireless device belongs.

[0202] System information (SI) can be divided into minimum SI and other SI. Minimum SI can be broadcast periodically. Minimum SI can include basic information required for initial access and information for obtaining any other SI that is broadcast periodically or provided on demand, i.e., scheduling information. Other SI can be broadcast, or provided in a dedicated manner, or triggered by the network, or upon request by a wireless device. Minimum SI can be transmitted via two different downlink channels using different messages (e.g., MasterInformationBlock and SystemInformationBlockType1). Another SI can be transmitted via SystemInformationBlockType2. For wireless devices in the RRC_Connected state, dedicated RRC signaling can be used for the request and delivery of other SI. For wireless devices in the RRC_Idle state and / or the RRC_Inactive state, the request can trigger a random access procedure.

[0203] The wireless device may report radio access capability information which may be static. The base station may request what capabilities the wireless device reports based on the frequency band information. When the network allows, the wireless device may send a temporary capability restriction request to signal the limited availability of certain capabilities to the base station (e.g., due to hardware sharing, interference, or overheating). The base station may confirm or deny the request. Temporary capability restrictions may be transparent to the 5GC (e.g., static capabilities may be stored in the 5GC).

[0204] When CA is configured, the wireless device may have an RRC connection with the network. During the RRC connection establishment / reestablishment / handover procedures, one serving cell may provide NAS mobility information, and upon RRC connection establishment / handover, one serving cell may provide security input. This cell may be referred to as a PCell. Depending on the capabilities of the wireless device, an SCell may be configured to form a serving cell set together with the PCell. The configured serving cell set for the wireless device may include one PCell and one or more SCells.

[0205] Reconfiguration, addition and removal of SCells may be performed by RRC. RRC may also add, remove or reconfigure SCells for use with the target PCell when switching within NR. When adding a new SCell, dedicated RRC signaling may be used to send all required system information for the SCell, i.e., when in connected mode, the wireless device may not need to obtain broadcast system information directly from the SCell.

[0206] The purpose of the RRC connection reconfiguration procedure may be to modify the RRC connection (e.g., to establish, modify and / or release RBs, perform handovers, set up, modify and / or release measurements, add, modify and / or release SCells and cell groups). As part of the RRC connection reconfiguration procedure, NAS-specific information may be delivered from the network to the wireless device. The RRCConnectionReconfiguration message may be a command to modify the RRC connection. It may convey information for measurement configuration, mobility control, radio resource configuration (e.g., RBs, MAC primary configuration, and physical channel configuration), including any associated dedicated NAS information and security configuration. If the received RRC connection reconfiguration message includes sCellToReleaseList, the wireless device may perform an SCell release. If the received RRC connection reconfiguration message includes sCellToAddModList, the wireless device may perform an SCell addition or modification.

[0207] The RRC connection establishment (or re-establishment, restoration) procedure may be to establish (or re-establish, restore) an RRC connection. The RRC connection establishment procedure may include SRB1 establishment. The RRC connection establishment procedure may be used to transfer initial NAS dedicated information / messages from the wireless device to the E-UTRAN. The RRCConnectionReestablishment message may be used to re-establish SRB1.

[0208] The measurement report procedure may be to transfer the measurement results from the wireless device to the NG-RAN. After successful security activation, the wireless device may initiate the measurement report procedure. The measurement results may be transmitted using a measurement report message.

In Figure 4A , Figure 4B , Figure 4C , Figure 4D , Figure 6 , Fig. 7A , Figure 7B , Figure 8 Exemplary embodiments of radio technologies implemented in the communication interfaces 310, 320A, 320B and wireless links 330A, 330B are shown in EMBODIMENTS and the associated text.

[0218] Figure 4A , Figure 4B , Figure 4C and Figure 4D is an example diagram of uplink and downlink signal transmission according to aspects of an embodiment of the present disclosure. Figure 4AAn exemplary uplink transmitter for at least one physical channel is shown. A baseband signal representing a physical uplink shared channel may perform one or more functions. The one or more functions may include at least one of the following: scrambling; modulating scrambled bits to generate complex-valued symbols; mapping complex-valued modulated symbols onto one or several transmission layers; transform precoding to generate complex-valued symbols; precoding of complex-valued symbols; mapping of precoded complex-valued symbols to resource elements; generating a complex-valued time-domain single carrier frequency division multiple access (SC-FDMA) or CP-OFDM signal for an antenna port; and the like. In an example, when transform precoding is enabled, an SC-FDMA signal for uplink transmission may be generated. In an example, when transform precoding is not enabled, the uplink transmission may be performed by Figure 4A Generate a CP-OFDM signal for uplink transmission. These functions are shown as examples, and it is contemplated that other mechanisms may be implemented in various embodiments.

[0219] An exemplary structure for modulation and up-conversion of the carrier frequency of a complex-valued SC-FDMA or CP-OFDM baseband signal and / or a complex-valued physical random access channel (PRACH) baseband signal for an antenna port is shown in Figure 4B In. Filtering can be applied before transmission.

[0220] Figure 4C An exemplary structure for downlink transmission is shown in . A baseband signal representing a downlink physical channel may perform one or more functions. The one or more functions may include: scrambling coded bits in a codeword to be transmitted on a physical channel; modulating the scrambled bits to generate complex-valued modulation symbols; mapping the complex-valued modulation symbols to one or several transmission layers; precoding of complex-valued modulation symbols on layers for transmission on antenna ports; mapping complex-valued modulation symbols for antenna ports to resource elements; generating complex-valued time-domain OFDM signals for antenna ports; and the like. These functions are shown as examples, and it is contemplated that other mechanisms may be implemented in various embodiments.

[0221] In an example, a gNB may transmit a first symbol and a second symbol to a wireless device on an antenna port. The wireless device may infer a channel (e.g., fading gain, multipath delay, etc.) used to communicate the second symbol on the antenna port from the channel used to communicate the first symbol on the antenna port. In an example, the first antenna port and the second antenna port may be quasi-co-located if one or more large-scale properties of a channel on which the first symbol on the first antenna port is communicated may be inferred from a channel on which the second symbol on the second antenna port is communicated. The one or more large-scale properties may include at least one of: delay spread; Doppler spread; Doppler shift; average gain; average delay; and / or spatial receive (Rx) parameters.

[0222] An exemplary modulation and up-conversion of the carrier frequency of a complex-valued OFDM baseband signal for an antenna port is shown in Figure 4D Filtering may be employed prior to transmission.

[0223] Figure 5A is a diagram of an exemplary uplink channel map and exemplary uplink physical signals. Figure 5B is a diagram of an exemplary downlink channel mapping and downlink physical signals. In an example, the physical layer may provide one or more information transfer services to the MAC and / or one or more higher layers. For example, the physical layer may provide the one or more information transfer services to the MAC via one or more transport channels. The information transfer service may indicate the manner and characteristics of transferring data over the radio interface.

[0224] In an exemplary embodiment, the radio network may include one or more downlink and / or uplink transmission channels. For example, Figure 5A The figure in FIG. 5 shows exemplary uplink transport channels including an uplink shared channel (UL-SCH) 501 and a random access channel (RACH) 502. Figure 5B 5 shows an exemplary downlink transport channel including a downlink shared channel (DL-SCH) 511, a paging channel (PCH) 512, and a broadcast channel (BCH) 513. The transport channels may be mapped to one or more corresponding physical channels. For example, UL-SCH 501 may be mapped to a physical uplink shared channel (PUSCH) 503. RACH 502 may be mapped to PRACH 505. DL-SCH 511 and PCH 512 may be mapped to a physical downlink shared channel (PDSCH) 514. BCH 513 may be mapped to a physical broadcast channel (PBCH) 516.

[0225] There may be one or more physical channels without corresponding transport channels. The one or more physical channels may be used for uplink control information (UCI) 509 and / or downlink control information (DCI) 517. For example, a physical uplink control channel (PUCCH) 504 may carry UCI 509 from a UE to a base station. For example, a physical downlink control channel (PDCCH) 515 may carry DCI 517 from a base station to a UE. When UCI 509 and PUSCH 503 transmissions may overlap at least partially in a time slot, NR may support UCI 509 multiplexing in PUSCH 503. UCI 509 may include at least one of CSI, acknowledgment (ACK) / negative acknowledgment (NACK), and / or a scheduling request. DCI 517 on PDCCH 515 may indicate at least one of the following: one or more downlink assignments and / or one or more uplink scheduling grants.

[0226] In the uplink, the UE may transmit one or more reference signals (RS) to the base station. For example, the one or more RSs may be at least one of a demodulation-RS (DM-RS) 506, a phase tracking-RS (PT-RS) 507, and / or a sounding RS (SRS) 508. In the downlink, the base station may transmit (e.g., unicast, multicast, and / or broadcast) one or more RSs to the UE. For example, the one or more RSs may be at least one of a primary synchronization signal (PSS) / secondary synchronization signal (SSS) 521, a CSI-RS 522, a DM-RS 523, and / or a PT-RS 524.

[0227] In an example, the UE may transmit one or more uplink DM-RS 506 to the base station for channel estimation, for example, for coherent demodulation of one or more uplink physical channels (e.g., PUSCH 503 and / or PUCCH 504). For example, the UE may transmit at least one uplink DM-RS 506 to the base station using PUSCH 503 and / or PUCCH 504, wherein the at least one uplink DM-RS 506 may span the same frequency range as the corresponding physical channel. In an example, the base station may configure the UE using one or more uplink DM-RS configurations. At least one DM-RS configuration may support a front-loaded DM-RS pattern. The front-loaded DM-RS may be mapped on one or more OFDM symbols (e.g., 1 or 2 adjacent OFDM symbols). One or more additional uplink DM-RSs may be configured to be transmitted at one or more symbols of PUSCH and / or PUCCH. The base station may semi-statistically configure the UE using the maximum number of front-loaded DM-RS symbols for PUSCH and / or PUCCH. For example, the UE may schedule single-symbol DM-RS and / or dual-symbol DM-RS based on the maximum number of front-loaded DM-RS symbols, wherein the base station may configure the UE with one or more additional uplink DM-RS for PUSCH and / or PUCCH. The new radio network may, for example, support a common DM-RS structure for DL ​​and UL at least for CP-OFDM, wherein the DM-RS position, DM-RS pattern and / or scrambling sequence may be the same or different.

[0228] In an example, whether the uplink PT-RS 507 exists may depend on the RRC configuration. For example, the presence of the uplink PT-RS may be UE-specific. For example, the presence and / or pattern of the uplink PT-RS 507 in the scheduled resources may be UE-specifically configured by a combination of RRC signaling and / or an association with one or more parameters (e.g., modulation and coding scheme (MCS)) for other purposes that may be indicated by the DCI. When configured, the dynamic presence of the uplink PT-RS 507 may be associated with one or more DCI parameters including at least the MCS. The radio network may support multiple uplink PT-RS densities defined in the time / frequency domain. When present, the frequency domain density may be associated with at least one configuration of the scheduled bandwidth. The UE may use the same precoding for the DMRS port and the PT-RS port. The number of PT-RS ports may be less than the number of DM-RS ports in the scheduled resources. For example, the uplink PT-RS 507 may be limited to the scheduled time / frequency duration of the UE.

[0229] In an example, the UE may transmit SRS 508 to a base station for channel state estimation, thereby supporting uplink channel-dependent scheduling and / or link adaptation. For example, the SRS 508 transmitted by the UE may allow the base station to estimate the uplink channel state at one or more different frequencies. The base station scheduler may use the uplink channel state to assign one or more resource blocks of high quality for uplink PUSCH transmission from the UE. The base station may semi-statistically configure the UE using one or more SRS resource sets. For the SRS resource set, the base station may configure the UE using one or more SRS resources. The applicability of the SRS resource set may be configured by a higher layer (e.g., RRC) parameter. For example, when the higher layer parameter indicates beam management, the SRS resources in each of the one or more SRS resource sets may be transmitted at a certain moment. The UE may simultaneously transmit one or more SRS resources in different SRS resource sets. The new radio network may support aperiodic, periodic, and / or semi-persistent SRS transmissions. The UE may transmit SRS resources based on one or more trigger types, wherein the one or more trigger types may include higher layer signaling (e.g., RRC) and / or one or more DCI formats (e.g., at least one DCI format may be used for the UE to select at least one configured SRS resource set from one or more configured SRS resource sets. SRS trigger type 0 may refer to SRS triggered based on higher layer signaling. SRS trigger type 1 may refer to SRS triggered based on one or more DCI formats. In an example, when PUSCH 503 and SRS 508 are transmitted in the same time slot, the UE may be configured to transmit SRS 508 after transmission of PUSCH 503 and the corresponding uplink DM-RS 506.

[0230] In an instance, the base station may semi-statistically configure the UE using one or more SRS configuration parameters indicating at least one of the following: an SRS resource configuration identifier, a number of SRS ports, a time domain behavior of the SRS resource configuration (e.g., an indication of periodic, semi-persistent, or aperiodic SRS), a slot (mini-slot and / or subframe) level periodicity and / or offset of periodic and / or aperiodic SRS resources, a number of OFDM symbols in the SRS resources, a starting OFDM symbol for the SRS resources, an SRS bandwidth, a frequency hopping bandwidth, a cyclic shift, and / or an SRS sequence ID.

[0231] In an example, in the time domain, the SS / PBCH block may include one or more OFDM symbols within the SS / PBCH block (e.g., 4 OFDM symbols numbered in increasing order from 0 to 3). The SS / PBCH block may include a PSS / SSS 521 and a PBCH 516. In an example, in the frequency domain, the SS / PBCH block may include one or more consecutive subcarriers within the SS / PBCH block (e.g., 240 consecutive subcarriers, the subcarriers are numbered in increasing order from 0 to 239). For example, the PSS / SSS 521 may occupy 1 OFDM symbol and 127 subcarriers. For example, the PBCH 516 may span 3 OFDM symbols and 240 subcarriers. The UE may assume that one or more SS / PBCH blocks transmitted using the same block index may be quasi-co-located, for example, with respect to Doppler spread, Doppler shift, average gain, average delay, and spatial Rx parameters. The UE may not assume quasi-co-location of other SS / PBCH block transmissions. The periodicity of the SS / PBCH blocks may be configured by the radio network (e.g., via RRC signaling), and the subcarrier spacing may determine the one or more time locations at which the SS / PBCH blocks may be sent. In an example, the UE may assume a band-specific subcarrier spacing for the SS / PBCH blocks unless the radio network has configured the UE to assume a different subcarrier spacing.

[0232] In an example, a downlink CSI-RS 522 may be used for the UE to obtain channel state information. The radio network may support periodic, aperiodic, and / or semi-persistent transmission of the downlink CSI-RS 522. For example, the base station may semi-statistically configure and / or reconfigure the UE using periodic transmission of the downlink CSI-RS 522. The configured CSI-RS resources may be activated and / or deactivated. For semi-persistent transmission, the activation and / or deactivation of the CSI-RS resources may be dynamically triggered. In an example, the CSI-RS configuration may include one or more parameters indicating the number of at least antenna ports. For example, the base station may configure the UE using 32 ports. The base station may semi-statistically configure the UE using one or more CSI-RS resource sets. One or more CSI-RS resources may be allocated to one or more UEs from one or more CSI-RS resource sets. For example, the base station may semi-statistically configure one or more parameters indicating CSI RS resource mapping, such as the time domain position of one or more CSI-RS resources, the bandwidth of the CSI-RS resources, and / or periodicity. In an example, the UE may be configured to employ the same OFDM symbol for the downlink CSI-RS 522 and the control resource set (core set) when the downlink CSI-RS 522 and the core set are quasi-co-located in space and the resource elements associated with the downlink CSI-RS 522 are outside the PRB configured for the core set. In an example, the UE may be configured to employ the same OFDM symbol for the downlink CSI-RS 522 and the SSB / PBCH when the downlink CSI-RS 522 and the SSB / PBCH are quasi-co-located in space and the resource elements associated with the downlink CSI-RS 522 are outside the PRB configured for the SSB / PBCH.

[0233] In an example, the UE may transmit one or more downlink DM-RS 523 to a base station for channel estimation, e.g., for coherent demodulation of one or more downlink physical channels (e.g., PDSCH 514). For example, the radio network may support one or more variable and / or configurable DM-RS patterns for data demodulation. At least one downlink DM-RS configuration may support a front-load DM-RS pattern. The front-load DM-RS may be mapped on one or more OFDM symbols (e.g., 1 or 2 adjacent OFDM symbols). The base station may semi-statistically configure the UE with a maximum number of front-load DM-RS symbols for PDSCH 514. For example, the DM-RS configuration may support one or more DM-RS ports. For example, for single-user-MIMO, the DM-RS configuration may support at least 8 orthogonal downlink DM-RS ports. For example, for multi-user-MIMO, the DM-RS configuration may support 12 orthogonal downlink DM-RS ports. The radio network may support a common DM-RS structure for DL ​​and UL, for example, at least for CP-OFDM, where the DM-RS positions, DM-RS patterns and / or scrambling sequences may be the same or different.

[0234] In an example, whether a downlink PT-RS 524 exists may depend on an RRC configuration. For example, the presence of a downlink PT-RS 524 may be UE-specific. For example, the presence and / or pattern of a downlink PT-RS 524 in a scheduled resource may be UE-specifically configured by a combination of RRC signaling and / or association with one or more parameters (e.g., MCS) for other purposes that may be indicated by a DCI. When configured, the dynamic presence of a downlink PT-RS 524 may be associated with one or more DCI parameters including at least an MCS. A radio network may support multiple PT-RS densities defined in a time / frequency domain. When present, a frequency domain density may be associated with at least one configuration of a scheduled bandwidth. The UE may use the same precoding for a DMRS port and a PT-RS port. The number of PT-RS ports may be less than the number of DM-RS ports in the scheduled resources. For example, a downlink PT-RS 524 may be limited to a scheduled time / frequency duration of the UE.

[0235] Figure 6 is a diagram depicting an example frame structure of a carrier according to aspects of an embodiment of the present disclosure. A multi-carrier OFDM communication system may include one or more carriers, for example, ranging from 1 to 32 carriers in the case of carrier aggregation, or ranging from 1 to 64 carriers in the case of dual connectivity. Different radio frame structures (e.g., for FDD and for TDD duplexing schemes) may be supported. Figure 6An example frame structure is shown. Downlink and uplink transmissions may be organized into radio frames 601. In this example, the radio frame duration is 10 milliseconds. In this example, the 10 millisecond radio frame 601 may be divided into ten equally sized subframes 602 having a duration of 1 millisecond. One or more subframes may include one or more time slots (e.g., time slots 603 and 605), depending on the subcarrier spacing and / or CP length. For example, subframes with 15kHz, 30kHz, 60kHz, 120kHz, 240kHz, and 480kHz subcarrier spacing may include one, two, four, eight, sixteen, and thirty-two time slots, respectively. Figure 6 In the embodiment of the present invention, a subframe can be divided into two equally sized time slots 603 with a duration of 0.5 milliseconds. For example, at an interval of 10 ms, 10 subframes can be used for downlink transmission and 10 subframes can be used for uplink transmission. Uplink and downlink transmissions can be split in the frequency domain. One or more time slots can include multiple OFDM symbols 604. The number of OFDM symbols 604 in a time slot 605 can depend on the cyclic prefix length. For example, for the same subcarrier spacing of up to 480kHz with normal CP, a time slot can be 14 OFDM symbols. For the same subcarrier spacing of 60kHz with extended CP, a time slot can be 12 OFDM symbols. A time slot can contain a downlink, an uplink, or a downlink part and an uplink part, etc.

[0236] Fig. 7A700. The diagram depicts an exemplary set of OFDM subcarriers according to aspects of an embodiment of the present disclosure. In an example, a gNB may communicate with a wireless device using a carrier having an exemplary channel bandwidth 700. One or more arrows in the diagram may depict subcarriers in a multi-carrier OFDM system. The OFDM system may use a technology such as OFDM technology, SC-FDMA technology, etc. In an example, arrow 701 shows a subcarrier that transmits an information symbol. In an example, a subcarrier spacing 702 between two consecutive subcarriers in a carrier may be any one of 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, etc. In an example, different subcarrier spacings may correspond to different transmission parameter sets. In an example, a transmission parameter set may include at least: a parameter set index; a value of the subcarrier spacing; a type of cyclic prefix (CP). In an example, a gNB may transmit to / receive from a UE on several subcarriers 703 in a carrier. In an example, due to guard bands 704 and 705, the bandwidth occupied by several subcarriers 703 (transmission bandwidth) may be less than the channel bandwidth 700 of the carrier. In an example, guard bands 704 and 705 may be used to reduce interference to and from one or more adjacent carriers. The number of subcarriers in a carrier (transmission bandwidth) may depend on the channel bandwidth and subcarrier spacing of the carrier. For example, for a carrier with a 20 MHz channel bandwidth and a 15 KHz subcarrier spacing, the transmission bandwidth may be 1024 subcarriers in number.

[0237] In an example, when CA configuration is utilized, the gNB and wireless device may communicate with multiple CCs. In an example, if CA is supported, different component carriers may have different bandwidths and / or subcarrier spacings. In an example, the gNB may transmit a first type of service to the UE on a first component carrier. The gNB may transmit a second type of service to the UE on a second component carrier. Different types of services may have different service requirements (e.g., data rate, latency, reliability), which may be suitable for transmission via different component carriers with different subcarrier spacings and / or bandwidths. Figure 7B An exemplary embodiment is shown. The first component carrier may include a first number of subcarriers 706 having a first subcarrier spacing 709. The second component carrier may include a second number of subcarriers 707 having a second subcarrier spacing 710. The third component carrier may include a third number of subcarriers 708 having a third subcarrier spacing 711. The carriers in the multi-carrier OFDM communication system may be contiguous carriers, non-contiguous carriers, or a combination of contiguous and non-contiguous carriers.

[0238] Figure 8801. In an example, a carrier may have a transmission bandwidth 801. In an example, a resource grid may be in a frequency domain 802 and a time domain 803 structure. In an example, a resource grid may include a first number of OFDM symbols and a second number of resource blocks in a subframe, starting from a common resource block for transmitting a parameter set and a carrier indicated by higher layer signaling (e.g., RRC signaling). In an example, in a resource grid, a resource unit identified by a subcarrier index and a symbol index may be a resource element 805. In an example, depending on a parameter set associated with a carrier, a subframe may include a first number of OFDM symbols 807. For example, when the subcarrier spacing of the parameter set of the carrier is 15KHz, the subframe may have 14 OFDM symbols for the carrier. When the subcarrier spacing of the parameter set is 30KHz, the subframe may have 28 OFDM symbols. When the subcarrier spacing of the parameter set is 60Khz, the subframe may have 56 OFDM symbols, etc. In an example, the second number of resource blocks included in the resource grid of the carrier can depend on the bandwidth and the numerology of the carrier.

[0239] like Figure 8 As shown, resource block 806 may include 12 subcarriers. In an example, multiple resource blocks may be grouped into resource block groups (RBGs) 804. In an example, the size of the RBG may depend on at least one of: an RRC message indicating an RBG size configuration; the size of the carrier bandwidth; or the size of a bandwidth portion of the carrier. In an example, the carrier may include multiple bandwidth portions. A first bandwidth portion of the carrier may have a different frequency location and / or bandwidth than a second bandwidth portion of the carrier.

[0240] In an example, the gNB may transmit downlink control information including downlink or uplink resource block assignments to the wireless device. The base station may transmit to the wireless device or receive from the wireless device a data packet (e.g., a transport block) scheduled and transmitted via one or more resource blocks and one or more time slots based on the downlink control information and / or parameters in one or more RRC messages. In an example, a start symbol of a first time slot relative to the one or more time slots may be indicated to the wireless device. In an example, the gNB may transmit to the wireless device or receive from the wireless device a data packet scheduled on one or more RBGs and one or more time slots.

[0241] In an instance, the gNB may transmit downlink control information including a downlink assignment to the wireless device via one or more PDCCHs. The downlink assignment may include parameters indicating at least a modulation and coding format; a resource allocation; and / or HARQ information related to the DL-SCH. In an instance, the resource allocation may include parameters for a resource block allocation; and / or a time slot allocation. In an instance, the gNB may dynamically allocate resources to the wireless device via a cell-radio network temporary identifier (C-RNTI) on one or more PDCCHs. The wireless device may monitor the one or more PDCCHs to find possible allocations when its downlink reception is enabled. Upon successful detection of the one or more PDCCHs, the wireless device may receive one or more downlink data packets on one or more PDSCHs scheduled by the one or more PDCCHs.

[0242] In an example, the gNB may allocate configured scheduled (CS) resources for downlink transmission to the wireless device. The gNB may transmit one or more RRC messages indicating the periodicity of the CS grant. The gNB may transmit the DCI via a PDCCH addressed to a configured scheduled-RNTI (CS-RNTI) that activates the CS resources. The DCI may include a parameter indicating that the downlink grant is a CS grant. The CS grant may be implicitly reused according to the periodicity defined by the one or more RRC messages until deactivated.

[0243] In an example, the gNB may transmit downlink control information including an uplink grant to the wireless device via one or more PDCCHs. The uplink grant may include parameters indicating at least a modulation and coding format; a resource allocation; and / or HARQ information related to the UL-SCH. In an example, the resource allocation may include parameters for resource block allocation; and / or time slot allocation. In an example, the gNB may dynamically allocate resources to the wireless device via the C-RNTI on one or more PDCCHs. The wireless device may monitor the one or more PDCCHs for possible resource allocations. Upon successful detection of the one or more PDCCHs, the wireless device may transmit one or more uplink data packets via one or more PUSCHs scheduled by the one or more PDCCHs.

[0244] In an example, the gNB may allocate CS resources for uplink data transmission to the wireless device. The gNB may transmit one or more RRC messages indicating the periodicity of the CS grant. The gNB may transmit DCI via a PDCCH addressed to the CS-RNTI that activated the CS resources. The DCI may include a parameter indicating that the uplink grant is a CS grant. The CS grant may be implicitly reused according to the periodicity defined by the one or more RRC messages until deactivated.

[0245] In an example, a base station may transmit DCI / control signaling via PDCCH. DCI may adopt a format in a variety of formats. DCI may include downlink and / or uplink scheduling information (e.g., resource allocation information, HARQ related parameters, MCS), a request for CSI (e.g., aperiodic CQI report), a request for SRS, an uplink power control command for one or more cells, one or more timing information (e.g., TB transmission / reception timing, HARQ feedback timing, etc.), etc. In an example, DCI may indicate an uplink grant including transmission parameters for one or more transport blocks. In an example, DCI may indicate a downlink assignment indicating parameters for receiving one or more transport blocks. In an example, a base station may use DCI to initiate contention-free random access at a wireless device. In an example, a base station may transmit a DCI including a slot format indicator (SFI) that notifies a slot format. In an example, a base station may transmit a DCI including a preemptive indication notifying one or more PRBs and / or one or more OFDM symbols, wherein the UE may assume that there is no transmission intended for the UE. In an example, a base station may transmit a DCI for group power control of a PUCCH or PUSCH or SRS. In an example, the DCI may correspond to an RNTI. In an example, a wireless device may obtain an RNTI (e.g., C-RNTI) in response to completing initial access. In an example, a base station may configure an RNTI (e.g., CS-RNTI, TPC-CS-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI, TPC-SRS-RNTI) for wireless. In an example, a wireless device may calculate an RNTI (e.g., a wireless device may calculate an RA-RNTI based on resources used to transmit a preamble). In an example, the RNTI may have a preconfigured value (e.g., P-RNTI or SI-RNTI). In an example, a wireless device may monitor a group common search space, which may be used by a base station to transmit a DCI intended for a group of UEs. In an example, the group common DCI may correspond to a RNTI configured commonly for a group of UEs. In an example, the wireless device may monitor a UE-specific search space. In an example, the UE-specific DCI may correspond to a RNTI configured for the wireless device.

[0246] The NR system may support single beam operation and / or multi-beam operation. In multi-beam operation, the base station may perform downlink beam sweeping to provide coverage for a common control channel and / or downlink SS block that may include at least PSS, SSS and / or PBCH. The wireless device may use one or more RSs to measure the quality of the beam to the link. One or more SS blocks, or one or more CSI-RS resources associated with a CSI-RS resource index (CRI), or one or more DM-RSs of a PBCH may be used as RSs for measuring the quality of the beam to the link. The quality of the beam to the link may be defined as a reference signal received power (RSRP) value, or a reference signal received quality (RSRQ) value, and / or a CSI value measured on an RS resource. The base station may indicate whether the RS resource used to measure the quality of the beam to the link is quasi-co-located (QCL) with the DM-RS of the control channel. When the channel characteristics of the transmission to the wireless device from the RS and the transmission to the wireless device from the control channel are similar or identical under the configured criteria, the RS resources and DM-RS of the control channel may be referred to as QCL. In multi-beam operation, a wireless device may perform uplink beam sweeping to access a cell.

[0247] In an example, a wireless device may be configured to simultaneously monitor PDCCH on one or more beam pair links depending on the capabilities of the wireless device. This can increase robustness against beam pair link blocking. A base station may transmit one or more messages to configure a wireless device to monitor PDCCH on one or more beam pair links in different PDCCH OFDM symbols. For example, a base station may transmit higher layer signaling (e.g., RRC signaling) or MAC CE, which includes parameters for Rx beam settings of a wireless device for monitoring PDCCH on one or more beam pair links. A base station may transmit one or more DL RS antenna ports (e.g., cell-specific CSI-RS, or wireless device-specific CSI-RS, or SS blocks, or PBCH with or without DM-RS of PBCH) and an indication of spatial QCL assumptions between one or more DL RS antenna ports for demodulating DL control channels. Signaling for beam indication for PDCCH may be MAC CE signaling, or RRC signaling, or DCI signaling, or standardized transparent and / or implicit methods, and combinations of these signaling methods.

[0248] For reception of a unicast DL data channel, the base station may indicate spatial QCL parameters between one or more DL RS antenna ports and one or more DM-RS antenna ports of the DL data channel. The base station may transmit a DCI (e.g., a downlink grant) including information indicating one or more RS antenna ports. The information may indicate one or more RS antenna ports that may be QCLed with one or more DM-RS antenna ports. Different sets of one or more DM-RS antenna ports for a DL data channel may be indicated as different sets of QCLed with one or more RS antenna ports.

[0249] Fig. 9A is an example of beam sweeping in a DL channel. In the RRC_INACTIVE state or the RRC_IDLE state, the wireless device may assume that the SS blocks form an SS burst 940 and an SS burst set 950. The SS burst set 950 may have a given periodicity. For example, in multi-beam operation, the base station 120 may transmit SS blocks in multiple beams, thereby forming an SS burst 940 together. One or more SS blocks may be transmitted on one beam. If multiple SS bursts 940 are transmitted with multiple beams, the SS bursts together may form an SS burst set 950.

[0250] The wireless device may additionally use CSI-RS in multi-beam operation to estimate the beam quality of the link between the wireless device and the base station. A beam may be associated with a CSI-RS. For example, the wireless device may report a beam index as indicated in the CRI for downlink beam selection and associated with the RSRP value of the beam based on an RSRP measurement report on the CSI-RS. The CSI-RS may be transmitted on a CSI-RS resource including at least one of one or more antenna ports, one or more time or frequency radio resources. The CSI-RS resources may be configured in a cell-specific manner by common RRC signaling or in a wireless device-specific manner by dedicated RRC signaling and / or L1 / L2 signaling. Multiple wireless devices covered by a cell may measure cell-specific CSI-RS resources. A dedicated subset of wireless devices covered by a cell may measure wireless device-specific CSI-RS resources.

[0251] CSI-RS resources may be transmitted periodically or using aperiodic transmission or using multiple or semi-persistent transmission. Fig. 9A In periodic transmission in the time domain, the base station 120 may periodically transmit the configured CSI-RS resources 940 using the configured periodicity. In aperiodic transmission, the configured CSI-RS resources may be transmitted in a dedicated time slot. In multiple or semi-persistent transmission, the configured CSI-RS resources may be transmitted within a configured period. The beam used for CSI-RS transmission may have a different beam width than the beam used for SS block transmission.

[0252] Fig. 9B is an example of a beam management procedure in an exemplary new radio network. The base station 120 and / or the wireless device 110 may perform a downlink L1 / L2 beam management procedure. One or more of the following downlink L1 / L2 beam management procedures may be performed within one or more wireless devices 110 and one or more base stations 120. In an example, the P-1 procedure 910 may be used to enable the wireless device 110 to measure one or more transmission (Tx) beams associated with the base station 120 to support the selection of a first set of Tx beams associated with the base station 120 and a first set of one or more Rx beams associated with the wireless device 110. In order to perform beamforming at the base station 120, the base station 120 may sweep a set of different TX beams. In order to perform beamforming at the wireless device 110, the wireless device 110 may sweep a set of different Rx beams. In an example, the P-2 procedure 920 may be used to enable the wireless device 110 to measure one or more Tx beams associated with the base station 120 to possibly change the first set of Tx beams associated with the base station 120. The P-2 procedure 920 may be performed on a potentially smaller set of beams for beam optimization than in the P-1 procedure 910. The P-2 procedure 920 may be a special case of the P-1 procedure 910. In an example, the P-3 procedure 930 may be used to enable the wireless device 110 to measure at least one Tx beam associated with the base station 120 to change a first set of Rx beams associated with the wireless device 110.

[0253] The wireless device 110 may transmit one or more beam management reports to the base station 120. In the one or more beam management reports, the wireless device 110 may indicate some beam pair quality parameters, including at least: one or more beam identifiers of a subset of configured beams; RSRP; precoding matrix indicator (PMI) / channel quality indicator (CQI) / rank indicator (RI). Based on the one or more beam management reports, the base station 120 may transmit a signal to the wireless device 110 indicating that the one or more beam pair links are one or more service beams. The base station 120 may use the one or more service beams to transmit PDCCH and PDSCH for the wireless device 110.

[0254] In an exemplary embodiment, the new radio network may support bandwidth adaptation (BA). In an example, the reception and / or transmission bandwidth configured by a UE adopting BA may not be large. For example, the reception and / or transmission bandwidth may not be as large as the bandwidth of the cell. The reception and / or transmission bandwidth may be adjustable. For example, the UE may change the reception and / or transmission bandwidth, for example, shrinking during low activity periods to save power. For example, the UE may change the location of the reception and / or transmission bandwidth in the frequency domain, for example, to increase scheduling flexibility. For example, the UE may change the subcarrier spacing, for example, to allow different services.

[0255] In an exemplary embodiment, a subset of the total cell bandwidth of a cell may be referred to as a bandwidth part (BWP). The base station may configure the UE with one or more BWPs to implement BA. For example, the base station may indicate to the UE which of the one or more (configured) BWPs is the active BWP.

[0256] Fig.10 1 is an example diagram of three configured BWPs: BWP1 (1010 and 1050) with a width of 40 MHz and a subcarrier spacing of 15 kHz; BWP2 (1020 and 1040) with a width of 10 MHz and a subcarrier spacing of 15 kHz; and BWP3 1030 with a width of 20 MHz and a subcarrier spacing of 60 kHz.

[0257] In an instance, a UE configured to operate in one or more BWPs of a cell may be configured by one or more higher layers (e.g., an RRC layer) of the cell with a set of one or more BWPs (e.g., up to four BWPs) for the UE (DL BWP set) to receive in a DL bandwidth via at least one parameter DL-BWP, and a set of one or more BWPs (e.g., up to four BWPs) for the UE (UL BWP set) to transmit in a UL bandwidth via at least one parameter UL-BWP for the cell.

[0258] To enable BA on PCell, the base station may configure the UE with one or more UL and DL BWP pairs. To enable BA on SCell (e.g., in case of CA), the base station may configure the UE with at least one or more DL BWPs (e.g., possibly none in UL).

[0259] In an example, the initial active DL BWP may be defined by at least one of the position and number of consecutive PRBs of a control resource set for at least one common search space, a subcarrier spacing, or a cyclic prefix. For operation on a PCell, one or more higher layer parameters may indicate at least one initial UL BWP for a random access procedure. If the UE is configured with a secondary carrier on a primary cell, the UE may be configured with an initial BWP for a random access procedure on the secondary carrier.

[0260] In an example, for unpaired spectrum operation, the UE may expect that the center frequency of the DL BWP may be the same as the center frequency of the UL BWP.

[0261] For example, for a DL BWP or UL BWP in a set of one or more DL BWPs or one or more UL BWPs, respectively, the base station can semi-statistically configure one or more parameters for the UE for the cell, and the one or more parameters indicate at least one of the following: subcarrier spacing; cyclic prefix; the number of consecutive PRBs; an index in a set of one or more DL BWPs and / or one or more UL BWPs; a link between a DL BWP and a UL BWP from a set of configured DL BWPs and UL BWPs; DCI detection of PDSCH reception timing; PDSCH reception of HARQ-ACK transmission timing value; DCI detection of PUSCH transmission timing value; and an offset of the first PRB of the DL bandwidth or the UL bandwidth relative to the first PRB of the bandwidth, respectively.

[0262] In an example, for a DL BWP in a set of one or more DL BWPs on a PCell, the base station may configure one or more control resource sets for the UE for at least one type of common search space and / or one UE-specific search space. For example, the base station may not configure the UE without a common search space on a PCell or on a PSCell in an active DL BWP.

[0263] For a UL BWP in a set of one or more UL BWPs, the base station may configure the UE with one or more resource sets for one or more PUCCH transmissions.

[0264] In an example, if the DCI includes a BWP indicator field, the BWP indicator field value may indicate an active DL BWP from a configured DL BWP set for one or more DL receptions. If the DCI includes a BWP indicator field, the BWP indicator field value may indicate an active UL BWP from a configured UL BWP set for one or more UL transmissions.

[0265] In an example, for PCell, the base station may semi-statistically configure the UE with a default DL BWP among the configured DL BWPs. If a default DL BWP is not provided to the UE, the default BWP may be the initial active DL BWP.

[0266] In an example, the base station may configure the UE with a timer value for the PCell. For example, when the UE detects a DCI indicating an active DL BWP other than the default DL BWP for paired spectrum operation or when the UE detects a DCI indicating an active DL BWP or UL BWP other than the default DL BWP for unpaired spectrum operation, the UE may start a timer called a BWP inactivity timer. If the UE does not detect a DCI during an interval for paired spectrum operation or for unpaired spectrum operation, the UE may increment the timer by an interval of a first value (e.g., the first value may be 1 millisecond or 0.5 milliseconds). In an example, the timer may expire when the timer is equal to the timer value. When the timer expires, the UE may switch from the active DL BWP to the default DL BWP.

[0267] In an example, the base station may semi-statistically configure the UE with one or more BWPs. The UE may switch the active BWP from the first BWP to the second BWP (e.g., the second BWP may be the default BWP) in response to receiving a DCI indicating that the second BWP is the active BWP and / or in response to expiration of a BWP inactivity timer. For example, Fig.10 1050 is an example diagram of three configured BWPs: BWP1 (1010 and 1050), BWP2 (1020 and 1040), and BWP3 (1030). BWP2 (1020 and 1040) may be default BWPs. BWP1 (1010) may be the initial active BWP. In an example, the UE may switch the active BWP from BWP1 1010 to BWP2 1020 in response to expiration of a BWP inactivity timer. For example, the UE may switch the active BWP from BWP2 1020 to BWP3 1030 in response to receiving a DCI indicating BWP3 1030 as the active BWP. Switching the active BWP from BWP3 1030 to BWP2 1040 and / or from BWP2 1040 to BWP1 1050 may be in response to receiving a DCI indicating an active BWP and / or in response to expiration of a BWP inactivity timer.

[0268] In an example, if the UE is configured with a default DL BWP and timer value among configured DL BWPs for a secondary cell, the UE procedure on the secondary cell may be the same as the UE procedure on the primary cell using the timer value for the secondary cell and the default DL BWP for the secondary cell.

[0269] In an example, if the base station configures the UE with a first active DL BWP and a first active UL BWP on a secondary cell or carrier, the UE may use the indicated DL BWP and the indicated UL BWP on the secondary cell as the respective first active DL BWP and first active UL BWP on the secondary cell or carrier.

[0270] Fig.11A and Fig. 11B Packet flows employing multiple connectivity (eg, dual connectivity, multiple connectivity, tight interworking, etc.) are shown. Fig.11A is an example diagram of a protocol structure of a wireless device 110 (eg, UE) with CA and / or multiple connectivity according to aspects of the embodiments. Fig. 11B 1 is an example diagram of a protocol structure of multiple base stations with CA and / or multiple connectivity according to aspects of an embodiment. The multiple base stations may include a master node MN 1130 (e.g., a master node, a master base station, a master gNB, a master eNB, etc.) and a secondary node SN 1150 (e.g., a secondary node, a secondary base station, a secondary gNB, a secondary eNB, etc.). The master node 1130 and the secondary node 1150 may work together to communicate with the wireless device 110.

[0271] When multiple connectivity is configured for the wireless device 110, the wireless device 110 that can support multiple reception / transmission functions in the RRC connection state can be configured to utilize radio resources provided by multiple schedulers of multiple base stations. Multiple base stations can be interconnected via non-ideal or ideal backhauls (e.g., Xn interface, X2 interface, etc.). The base stations involved in the multiple connectivity for a certain wireless device can perform at least one of two different roles: the base station can act as a primary base station or a secondary base station. In multiple connectivity, the wireless device can be connected to a primary base station and one or more secondary base stations. In an example, a primary base station (e.g., MN 1130) can provide a wireless device (e.g., wireless device 110) with a primary cell group (MCG) including a primary cell and / or one or more secondary cells. A secondary base station (e.g., SN 1150) can provide a secondary cell group (SCG) including a primary secondary cell (PSCell) and / or one or more secondary cells for a wireless device (e.g., wireless device 110).

[0272] In multiple connectivity, the radio protocol architecture adopted by the bearer may depend on how the bearer is set up. In an example, three different types of bearer setting options can be supported: MCG bearer, SCG bearer and / or split bearer. The wireless device can receive / transmit packets of the MCG bearer via one or more cells of the MCG, and / or can receive / transmit packets of the SCG bearer via one or more cells of the SCG. Multiple connectivity can also be described as having at least one bearer that is configured to use radio resources provided by a secondary base station. Multiple connectivity may or may not be configured / implemented in some exemplary embodiments.

[0273] In an example, a wireless device (e.g., wireless device 110) may: transmit and / or receive packets of an MCG bearer via an SDAP layer (e.g., SDAP 1110), a PDCP layer (e.g., NR PDCP 1111), an RLC layer (e.g., MN RLC 1114), and a MAC layer (e.g., MN MAC 1118); transmit and / or receive packets of a split bearer via an SDAP layer (e.g., SDAP 1110), a PDCP layer (e.g., NR PDCP 1112), one of a primary or secondary RLC layer (e.g., MN RLC 1115, SN RLC 1116), and one of a primary or secondary MAC layer (e.g., MN MAC 1118, SN MAC 1119); and / or transmit and / or receive packets of a split bearer via an SDAP layer (e.g., SDAP 1110), a PDCP layer (e.g., NR PDCP 1113), an RLC layer (e.g., SN RLC 1117), and a MAC layer (e.g., MN MAC 1119) to transmit and / or receive packets carried by SCG.

[0274] In an example, the master base station (e.g., MN 1130) and / or the secondary base station (e.g., SN 1150) may: transmit / receive packets carried by the MCG via the master or secondary node SDAP layer (e.g., SDAP 1120, SDAP 1140), the master or secondary node PDCP layer (e.g., NR PDCP 1121, NRPDCP 1142), the master node RLC layer (e.g., MN RLC 1124, MN RLC 1125) and the master node MAC layer (e.g., MN MAC1128); transmit / receive packets carried by the MCG via the master or secondary node SDAP layer (e.g., SDAP 1120, SDAP 1140), the master or secondary node PDCP layer (e.g., NR PDCP 1122, NR PDCP 1143), the secondary node RLC layer (e.g., SN RLC 1146, SNRLC 1147) and the secondary node MAC layer (e.g., SN MAC 1148) transmits / receives packets carried by the SCG; transmits / receives packets carried by the split node via the primary or secondary node SDAP layer (e.g., SDAP 1120, SDAP 1140), the primary or secondary node PDCP layer (e.g., NR PDCP 1123, NR PDCP 1141), the primary or secondary node RLC layer (e.g., MN RLC 1126, SN RLC 1144, SN RLC 1145, MN RLC 1127) and the primary or secondary node MAC layer (e.g., MN MAC 1128, SN MAC 1148).

[0275] In multiple connectivity, the wireless device may configure multiple MAC entities: one MAC entity for the primary base station (e.g., MN MAC 1118), and other MAC entities for the secondary base station (e.g., SN MAC 1119). In multiple connectivity, the configured service cell set for the wireless device may include two subsets: an MCG including service cells of the primary base station, and an SCG including service cells of the secondary base station. For SCG, one or more of the following configurations may apply: at least one cell of the SCG has a configured UL CC, and at least one cell of the SCG, referred to as a primary secondary cell (PSCell, PCell of the SCG, or sometimes referred to as PCell) is configured with PUCCH resources; when the SCG is configured, there may be at least one SCG bearer or one split bearer; after a physical layer problem or a random access problem is detected on the PSCell, or after a number of NR RLC retransmissions associated with the SCG have been reached, or after an access problem is detected on the PSCell during SCG addition or SCG change: the RRC connection reestablishment procedure may not be triggered, UL transmission to the cells of the SCG may be stopped, the primary base station may be notified of the SCG failure type by the wireless device, and for a split bearer, DL data delivery on the primary base station may be maintained; NR may be configured for the split bearer RLC Acknowledged Mode (AM) bearer; PCell and / or PSCell may not be deactivated; PSCell may be changed using an SCG change procedure (e.g., using security key change and RACH procedure); and / or bearer type change between split bearers and SCG bearers may or may not be supported, or simultaneous configuration of SCG and split bearers may be supported.

[0276] Regarding the interaction between the primary base station and the secondary base station for multiple connectivity, one or more of the following items may be applied: the primary base station and / or the secondary base station may maintain the RRM measurement configuration of the wireless device; the primary base station may decide (for example, based on the received measurement report, traffic conditions and / or bearer type) to request the secondary base station to provide additional resources (for example, service cells) for the wireless device; upon receiving the request from the primary base station, the secondary base station may create / modify a container, which may result in configuring an additional service cell for the wireless device (or determining that the secondary base station has no available resources to do so); for UE capability coordination, the primary base station may provide (partial) AS configuration and UE capabilities to the secondary base station; the primary base station and the secondary base station may coordinate with each other by adopting The RRC container (inter-node message) carried by the Xn message exchanges information about the UE configuration; the secondary base station can initiate the reconfiguration of the existing service cell of the secondary base station (for example, PUCCH towards the secondary base station); the secondary base station can decide which cell is the PSCell within the SCG; the primary base station can change or not change the content of the RRC configuration provided by the secondary base station; in the case of SCG addition and / or SCGSCell addition, the primary base station can provide the latest (or most recent) measurement results for one or more SCG cells; the primary base station and the secondary base station can receive information about SFN and / or each other's subframe offsets from OAM and / or via the Xn interface (for example, for the purpose of DRX alignment and / or measurement gap identification). In an example, when a new SCG SCell is added, dedicated RRC signaling can be used to send system information required for cells of CA, except for the SFN obtained from the MIB of the PSCell of the SCG.

[0277] Fig.12 is an example diagram of a random access procedure. One or more events may trigger the random access procedure. For example, the one or more events may be at least one of: initial access from RRC_IDLE, an RRC connection reestablishment procedure, a handover, DL or UL data arrival during RRC_CONNECTED when the UL synchronization state is asynchronous, a transition from RRC_Inactive, and / or a request for other system information. For example, a PDCCH command, a MAC entity, and / or a beam failure indication may initiate the random access procedure.

[0278] In an exemplary embodiment, the random access procedure may be at least one of a contention-based random access procedure and a contention-free random access procedure. For example, the contention-based random access procedure may include one or more Msg 1 1220 transmissions, one or more Msg2 1230 transmissions, one or more Msg3 1240 transmissions, and contention resolution 1250. For example, the contention-free random access procedure may include one or more Msg 1 1220 transmissions and one or more Msg2 1230 transmissions.

[0279] In an example, the base station may transmit (e.g., unicast, multicast, or broadcast) a RACH configuration 1210 to the UE via one or more beams. The RACH configuration 1210 may include one or more parameters indicating at least one of: a set of available PRACH resources for transmission of a random access preamble, an initial preamble power (e.g., a random access preamble initial reception target power), an RSRP threshold for selecting an SS block and a corresponding PRACH resource, a power ramp factor (e.g., a random access preamble power ramp step size), a random access preamble index, a maximum number of preamble transmissions, preamble groups A and B, a threshold (e.g., a message size) for determining a random access preamble group, a set of one or more random access preambles and corresponding one or more PRACH resources (if any) for a system information request, a set of one or more random access preambles and corresponding one or more PRACH resources (if any) for a beam failure recovery request, a time window for monitoring one or more RA responses, a time window for monitoring one or more responses to a beam failure recovery request, and / or a contention resolution timer.

[0280] In an example, Msg1 1220 may be one or more transmissions of a random access preamble. For a contention-based random access procedure, the UE may select an SS block with an RSRP above an RSRP threshold. If there is a random access preamble group B, the UE may select one or more random access preambles from group A or group B based on the potential Msg3 1240 size. If there is no random access preamble group B, the UE may select one or more random access preambles from group A. The UE may randomly (e.g., with equal probability or normal distribution) select a random access preamble index from one or more random access preambles associated with the selected group. If the base station semi-statistically configures the UE with an association between the random access preamble and the SS block, the UE may randomly select a random access preamble index from one or more random access preambles associated with the selected SS block and the selected group with equal probability.

[0281] For example, the UE may initiate a contention-free random access procedure based on a beam failure indication from a lower layer. For example, the base station may semi-statistically configure the UE with one or more contention-free PRACH resources for a beam failure recovery request associated with at least one of the SS blocks and / or CSI-RS. If at least one of the SS blocks having an RSRP higher than a first RSRP threshold among the associated SS blocks or at least one of the CSI-RS having an RSRP higher than a second RSRP threshold among the associated CSI-RS is available, the UE may select a random access preamble index corresponding to the selected SS block or CSI-RS from a set of one or more random access preambles for the beam failure recovery request.

[0282] For example, the UE may receive a random access preamble index from the base station via PDCCH or RRC for a contention-free random access procedure. If the base station does not configure the UE with at least one contention-free PRACH resource associated with an SS block or CSI-RS, the UE may select a random access preamble index. If the base station configures the UE with one or more contention-free PRACH resources associated with the SS block, and at least one SS block with an RSRP higher than a first RSRP threshold is available among the associated SS blocks, the UE may select the at least one SS block and select a random access preamble corresponding to the at least one SS block. If the base station configures the UE with one or more contention-free PRACH resources associated with a CSI-RS, and at least one CSI-RS with an RSRP higher than a second RSPR threshold is available among the associated CSI-RS, the UE may select the at least one CSI-RS and select a random access preamble corresponding to the at least one CSI-RS.

[0283] The UE may perform one or more Msg1 1220 transmissions by transmitting a selected random access preamble. For example, if the UE selects an SS block and is configured with an association between one or more PRACH opportunities and one or more SS blocks, the UE may determine a PRACH opportunity from one or more PRACH opportunities corresponding to the selected SS block. For example, if the UE selects a CSI-RS and is configured with an association between one or more PRACH opportunities and one or more CSI-RS, the UE may determine a PRACH opportunity from one or more PRACH opportunities corresponding to the selected CSI-RS. The UE may transmit the selected random access preamble to the base station via the selected PRACH opportunity. The UE may determine a transmission power for transmitting the selected random access preamble based at least on an initial preamble power and a power ramp factor. The UE may determine a RA-RNTI associated with a selected PRACH opportunity in which the selected random access preamble is transmitted. For example, the UE may not determine a RA-RNTI for a beam failure recovery request. The UE may determine the RA-RNTI based at least on an index of the first OFDM symbol and an index of a first slot of a selected PRACH opportunity and / or an uplink carrier index used for transmission of Msg1 1220 .

[0284] In an example, the UE may receive a random access response Msg 2 1230 from the base station. The UE may start a time window (e.g., ra-ResponseWindow) to monitor the random access response. For a beam failure recovery request, the base station may configure the UE with a different time window (e.g., bfr-ResponseWindow) to monitor the response to the beam failure recovery request. For example, the UE may start the time window (e.g., ra-ResponseWindow or bfr-ResponseWindow) at the start of the first PDCCH opportunity after a fixed duration of one or more symbols from the end of the preamble transmission. If the UE transmits multiple preambles, the UE may start the time window at the start of the first PDCCH opportunity after a fixed duration of one or more symbols from the end of the first preamble transmission. The UE may monitor the PDCCH of the cell for at least one random access response identified by the RA-RNTI or for at least one response to the beam failure recovery request identified by the C-RNTI while the timer of the time window is running.

[0285] In an example, if at least one random access response includes a random access preamble identifier corresponding to a random access preamble transmitted by the UE, the UE may consider that the reception of the random access response is successful. If the reception of the random access response is successful, the UE may consider that the contention-free random access procedure is successfully completed. If the contention-free random access procedure for a beam failure recovery request is triggered, the UE may consider that the contention-free random access procedure is successfully completed in the case where the PDCCH transmission is addressed to the C-RNTI. In an example, if at least one random access response includes a random access preamble identifier, the UE may consider that the random access procedure is successfully completed and may indicate receipt of an acknowledgment of a system information request for an upper layer. If the UE has signaled multiple preamble transmissions, the UE may stop transmitting the remaining preambles (if any) in response to successfully receiving the corresponding random access responses.

[0286] In an example, the UE may perform one or more Msg 3 1240 transmissions (e.g., for a contention-based random access procedure) in response to successful reception of a random access response. The UE may adjust uplink transmission timing based on a timing advance command indicated by the random access response, and may transmit one or more transport blocks based on an uplink grant indicated by the random access response. The subcarrier spacing for PUSCH transmission of Msg3 1240 may be provided by at least one higher layer (e.g., RRC) parameter. The UE may transmit a random access preamble via PRACH and Msg3 1240 via PUSCH on the same cell. The base station may indicate a UL BWP for PUSCH transmission of Msg3 1240 via a system information block. The UE may retransmit Msg 3 1240 using HARQ.

[0287] In an example, multiple UEs may perform Msg 1 1220 by transmitting the same preamble to a base station and receiving the same random access response including an identity (e.g., TC-RNTI) from the base station. Contention resolution 1250 may ensure that a UE does not mistakenly use the identity of another UE. For example, contention resolution 1250 may be based on a C-RNTI on a PDCCH or a UE contention resolution identity on a DL-SCH. For example, if a base station assigns a C-RNTI to a UE, the UE may perform contention resolution 1250 based on receipt of a PDCCH transmission addressed to the C-RNTI. In response to detecting the C-RNTI on the PDCCH, the UE may deem contention resolution 1250 successful and may deem the random access procedure to have been successfully completed. If the UE does not have a valid C-RNTI, contention resolution may be addressed by adopting the TC-RNTI. For example, if the MAC PDU is successfully decoded and the MAC PDU includes a UE contention resolution identity MAC CE that matches the CCCH SDU transmitted in Msg3 1250, then the UE may consider contention resolution 1250 to be successful and the random access procedure to be successfully completed.

[0288] Fig.13 It is an exemplary structure of a MAC entity according to aspects of an embodiment. In an example, a wireless device may be configured to operate in a multi-connectivity mode. A wireless device in RRC_CONNECTED with multiple RX / TX may be configured to utilize radio resources provided by multiple schedulers located in multiple base stations. Multiple base stations may be connected via non-ideal or ideal backhaul on an Xn interface. In an example, a base station among multiple base stations may act as a primary base station or a secondary base station. The wireless device may be connected to a primary base station and one or more secondary base stations. The wireless device may be configured with multiple MAC entities, for example, one MAC entity for a primary base station, and one or more other MAC entities for one or more secondary base stations. In an example, a configured service cell set for a wireless device may include two subsets: an MCG, which includes a service cell of a primary base station; and one or more SCGs, which include service cells of one or more secondary base stations. Fig.13 An exemplary structure of a MAC entity when MCG and SCG are configured for a wireless device is shown.

[0289] In an instance, at least one cell in an SCG may have a configured UL CC, where the cell of at least one cell may be referred to as a PSCell or a PCell of the SCG, or sometimes simply referred to as a PCell. The PSCell may be configured with PUCCH resources. In an instance, when an SCG is configured, there may be at least one SCG bearer or one split bearer. In an instance, after a physical layer problem or a random access problem is detected on the PSCell, or after the number of RLC retransmissions associated with the SCG is reached, or after an access problem is detected on the PSCell during an SCG addition or an SCG change: the RRC connection reestablishment procedure may not be triggered, UL transmissions to the cells of the SCG may be stopped, the UE may notify the primary base station of the SCG failure type, and DL data delivery on the primary base station may be maintained.

[0290] In an example, the MAC sublayer may provide services such as data transfer and radio resource allocation to an upper layer (e.g., 1310 or 1320). The MAC sublayer may include multiple MAC entities (e.g., 1350 and 1360). The MAC sublayer may provide data transfer services on logical channels. In order to accommodate different types of data transfer services, multiple types of logical channels may be defined. Logical channels may support the transfer of specific types of information. The type of logical channel may be defined by what type of information (e.g., control or data) is transferred. For example, BCCH, PCCH, CCCH, and DCCH may be control channels, and DTCH may be a traffic channel. In an example, a first MAC entity (e.g., 1310) may provide services on PCCH, BCCH, CCCH, DCCH, DTCH, and MAC control elements. In an example, a second MAC entity (e.g., 1320) may provide services on BCCH, DCCH, DTCH, and MAC control elements.

[0291] The MAC sublayer may anticipate services from the physical layer (e.g., 1330 or 1340), such as data transfer services, signaling of HARQ feedback, scheduling requests, or signaling of measurement values ​​(e.g., CQI). In an instance, in dual connectivity, two MAC entities may be configured for the wireless device: one for the MCG and one for the SCG. The MAC entity of the wireless device may process multiple transport channels. In an instance, a first MAC entity may process a first transport channel, including a PCCH of the MCG, a first BCH of the MCG, one or more first DL-SCHs of the MCG, one or more first UL-SCHs of the MCG, and one or more first RACHs of the MCG. In an instance, a second MAC entity may process a second transport channel, including a second BCH of the SCG, one or more second DL-SCHs of the SCG, one or more second UL-SCHs of the SCG, and one or more second RACHs of the SCG.

[0292] In an example, if a MAC entity is configured with one or more SCells, there may be multiple DL-SCHs per MAC entity, and there may be multiple UL-SCHs as well as multiple RACHs. In an example, there may be one DL-SCH and UL-SCH on a SpCell. In an example, for a SCell, there may be one DL-SCH, zero or one UL-SCH, and zero or one RACH. The DL-SCH may support reception using different parameter sets and / or TTI durations within the MAC entity. The UL-SCH may also support transmission using different parameter sets and / or TTI durations within the MAC entity.

[0293] In an example, the MAC sublayer may support different functions and these functions may be controlled using control (e.g., 1355 or 1365) elements. Functions performed by the MAC entity may include mapping between logical channels and transport channels (e.g., in uplink or downlink), multiplexing (e.g., 1352 or 1362) MAC SDUs from one or different logical channels to a transport block (TB) to be delivered to a physical layer on a transport channel (e.g., in uplink), demultiplexing (e.g., 1352 or 1362) MAC SDUs from a transport block (TB) delivered from a physical layer on a transport channel to one or different logical channels (e.g., in downlink), scheduling information reporting (e.g., in uplink), error correction by HARQ in uplink or downlink (e.g., 1363), and logical channel prioritization in uplink (e.g., 1351 or 1361). The MAC entity may handle a random access procedure (e.g., 1354 or 1364).

[0294] Fig.14 is an example diagram of a RAN architecture including one or more base stations. In an example, a protocol stack (e.g., RRC, SDAP, PDCP, RLC, MAC, and PHY) can be supported at a node. A base station (e.g., 120A or 120B) may include a base station central unit (CU) (e.g., gNB-CU 1420A or 1420B) and at least one base station distributed unit (DU) (e.g., gNB-DU1430A, 1430B, 1430C, or 1430D) (if functional division is configured). The upper protocol layers of the base station may be located in the base station CU, and the lower layers of the base station may be located in the base station DU. The F1 interface (e.g., CU-DU interface) connecting the base station CU and the base station DU may be an ideal or non-ideal backhaul. F1-C may provide a control plane connection via the F1 interface, and F1-U may provide a user plane connection via the F1 interface. In an example, an Xn interface may be configured between the base station CUs.

[0295] In an example, the base station CU may include an RRC function, an SDAP layer, and a PDCP layer, and the base station DU may include an RLC layer, a MAC layer, and a PHY layer. In an example, various functional splitting options between the base station CU and the base station DU are possible by locating different combinations of upper protocol layers (RAN functions) in the base station CU and different combinations of lower protocol layers (RAN functions) in the base station DU. The functional splitting may support the flexibility of moving protocol layers between the base station CU and the base station DU according to service requirements and / or network environment.

[0296] In an instance, the functional splitting options may be configured for each base station, each base station CU, each base station DU, each UE, each bearer, each slice, or at other granularities. In each base station CU split, the base station CU may have a fixed splitting option, and the base station DU may be configured to match the splitting option of the base station CU. In each base station DU split, the base station DU may be configured with different splitting options, and the base station CU may provide different splitting options for different base station DUs. In each UE split, the base station (base station CU and at least one base station DU) may provide different splitting options for different wireless devices. In each bearer split, different splitting options may be used for different bearers. In each slice splicing, different splitting options may be applied to different slices.

[0297] Fig.151 is an example diagram showing RRC state transitions of a wireless device. In an example, the wireless device may be in at least one of an RRC connected state (e.g., RRC connected 1530, RRC_Connected), an RRC idle state (e.g., RRC idle 1510, RRC_Idle), and / or an RRC inactive state (e.g., RRC inactive 1520, RRC_Inactive). In an example, in the RRC connected state, the wireless device may have at least one RRC connection with at least one base station (e.g., gNB and / or eNB), and the base station may have a UE context of the wireless device. The UE context (e.g., wireless device context) may include at least one of an access layer context, one or more radio link configuration parameters, bearer (e.g., data radio bearer (DRB), signaling radio bearer (SRB), logical channel, QoS flow, PDU session, etc.) configuration information, security information, PHY / MAC / RLC / PDCP / SDAP layer configuration information, and / or similar configuration information for the wireless device. In an example, in the RRC idle state, the wireless device may not have an RRC connection with the base station, and the UE context of the wireless device may not be stored in the base station. In an example, in the RRC inactive state, the wireless device may not have an RRC connection with the base station. The UE context of the wireless device may be stored in the base station, which may be referred to as an anchor base station (e.g., a last serving base station).

[0298] In an example, the wireless device may transition the UE RRC state between the RRC idle state and the RRC connected state in two ways (e.g., connection release 1540 or connection establishment 1550; or connection reestablishment) and / or between the RRC inactive state and the RRC connected state in two ways (e.g., connection deactivation 1570 or connection recovery 1580). In an example, the wireless device may transition its RRC state from the RRC inactive state to the RRC idle state (e.g., connection release 1560).

[0299] In an example, an anchor base station may be a base station that can maintain a UE context (wireless device context) of a wireless device at least during a time period that the wireless device stays in a RAN notification area (RNA) of the anchor base station and / or the wireless device stays in an RRC inactive state. In an example, the anchor base station may be a base station to which a wireless device in an RRC inactive state was last connected in the latest RRC connected state, or a base station where the wireless device last performed an RNA update procedure. In an example, an RNA may include one or more cells operated by one or more base stations. In an example, a base station may belong to one or more RNAs. In an example, a cell may belong to one or more RNAs.

[0300] In an example, the wireless device may transition the UE RRC state from the RRC connected state to the RRC inactive state in the base station. The wireless device may receive RNA information from the base station. The RNA information may include at least one of an RNA identifier, one or more cell identifiers of one or more cells of the RNA, a base station identifier, an IP address of the base station, an AS context identifier of the wireless device, a recovery identifier, etc.

[0301] In an instance, an anchor base station may broadcast a message (e.g., a RAN paging message) to a base station of the RNA to reach a wireless device in an RRC inactive state, and / or a base station receiving a message from the anchor base station may broadcast and / or multicast another message (e.g., a paging message) over an air interface to wireless devices in its coverage area, a cell coverage area, and / or a beam coverage area associated with the RNA.

[0302] In an example, when a wireless device in an RRC inactive state moves to a new RNA, the wireless device may perform an RNA update (RNAU) procedure, which may include a random access procedure and / or a UE context retrieval procedure for the wireless device. The UE context retrieval may include: a base station receiving a random access preamble from the wireless device; and the base station extracting a UE context of the wireless device from an old anchor base station. The extraction may include: sending a retrieve UE context request message including a recovery identifier to the old anchor base station, and receiving a retrieve UE context response message including the UE context of the wireless device from the old anchor base station.

[0303] In an exemplary embodiment, a wireless device in an RRC inactive state may select a cell to reside in based on measurement results of at least one or more cells, cells for which the wireless device may monitor RNA paging messages, and / or core network paging messages from a base station. In an example, a wireless device in an RRC inactive state may select a cell to perform a random access procedure to restore an RRC connection and / or transmit one or more packets to a base station (e.g., to a network). In an example, if the selected cell belongs to an RNA different from the RNA of the wireless device in an RRC inactive state, the wireless device may initiate a random access procedure to perform an RNA update procedure. In an example, if the wireless device in an RRC inactive state has one or more packets in a buffer to transmit to the network, the wireless device may initiate a random access procedure to transmit one or more packets to a base station of a cell selected by the wireless device. The random access procedure may be performed using two messages (e.g., level 2 random access) and / or four messages (e.g., level 4 random access) between the wireless device and the base station.

[0304] In an exemplary embodiment, a base station receiving one or more uplink packets from a wireless device in an RRC inactive state may extract a UE context of the wireless device by transmitting a retrieve UE context request message for the wireless device to an anchor base station of the wireless device based on at least one of an AS context identifier, an RNA identifier, a base station identifier, a recovery identifier, and / or a cell identifier received from the wireless device. In response to extracting the UE context, the base station may transmit a path switch request for the wireless device to a core network entity (e.g., AMF, MME, etc.). The core network entity may update a downlink tunnel endpoint identifier of one or more bearers established for the wireless device between a user plane core network entity (e.g., UPF, S-GW, etc.) and a RAN node (e.g., a base station), for example, changing the downlink tunnel endpoint identifier from an address of the anchor base station to an address of the base station.

[0305] The gNB may communicate with the wireless device via a wireless network that employs one or more new radio technologies. The one or more radio technologies may include at least one of the following: multiple technologies associated with the physical layer; multiple technologies associated with the medium access control layer; and / or multiple technologies associated with the radio resource control layer. Exemplary embodiments that enhance the one or more radio technologies may improve the performance of the wireless network. Exemplary embodiments may increase system throughput or data transmission rate. Exemplary embodiments may reduce battery consumption of the wireless device. Exemplary embodiments may improve latency for data transmission between the gNB and the wireless device. Exemplary embodiments may improve network coverage of the wireless network. Exemplary embodiments may improve transmission efficiency of the wireless network.

[0306] In an example, a PUSCH / PUCCH / SRS / PRACH transmission opportunity ii may be indexed by a slot within a frame having a system frame number SFNSFN The number of the first symbol SS and consecutive symbols L in a time slot is limited.

[0307] For PUSCH transmission on active UL BWPb of carrier f serving cell c, the wireless device may calculate the transmission power P PUSCH,b,f,c (i,j,q d ,l)P PUSCH,b,f,c (i,j,q d ,l) linear value Its parameters are described elsewhere in this specification. If a PUSCH transmission is scheduled by DCI format 0_1, and when txConfig in PUSCH-Config is set to "codebook", the wireless device may scale the linear value by the ratio of the number of antenna ports with non-zero PUSCH transmission power to the maximum number of SRS ports supported by the wireless device in one SRS resource. For example, the wireless device evenly distributes power across the antenna ports on which the wireless device transmits PUSCH with non-zero power. For example, two PUSCH transmissions are scheduled in different SRS resource sets (e.g., different antenna groups and / or panels), the wireless device may determine the PUSCH power for each SRS resource set (e.g., antenna group and / or panel), and scale the sum of one or more determined PUSCH powers for different SRS resource sets (e.g., different antenna groups and / or panels), for example, if the sum exceeds (e.g., is greater than and / or equal to) PUSCH. CMAX,f,c (i)P CMAX,f,c (i)

[0308] For example, if the wireless device transmits PUSCH on the active UL BWPb of carrier f of serving cell c using the parameter set configuration with index j and the PUSCH power control adjustment state with index l, the wireless device may set the PUSCH transmission power P in PUSCH transmission opportunity i to PUSCH,b,f,c (i,j,q d ,l) is determined as

[0309]

[0310] In the example, P CMAX,f,c (i) may be the configured wireless device transmission power for carrier f of serving cell c in PUSCH transmission opportunity i. O_PUSCH,b,f,c (j) can be composed of component P O_NOMINAL_PUSCH,f,c (j) and the component P O_UE_PUSCH,b,f,c (j), where j∈{0,1,...,J-1}.

[0311] For example, if the wireless device is not provided with P0-PUSCH-AlphaSet, or for PUSCH transmission scheduled by RAR UL grant, the wireless device may determine j=0, P O_UE_PUSCH,b,f,c (0) = 0 and P O_NOMINAL_PUSCH,f,c (0) = P O_PRE +Δ PREAMBLE_Msg3 , where higher layer parameters, e.g., preambleReceivedTargetPower (for P O_PRE ) and msg3-DeltaPreamble (for ΔPREAMBLE_Msg3 ) may be provided by a higher layer, or if msg3-DeltaPreamble is not provided for carrier f serving cell c, then Δ PREAMBLE_Msg3 =0dB.

[0312] In this example, for a PUSCH (re)transmission configured by ConfiguredGrantConfig, j=1, and P is provided by p0-NominalWithoutGrant O_NOMINAL_PUSCH,f,c (1), or P if p0-NominalWithoutGrant is not provided O_NOMINAL_PUSCH,f,c (1) = P O_NOMINAL_PUSCH,f,c (0), and P is provided by p0 obtained from p0-PUSCH-Alpha in ConfiguredGrantConfig O_UE_PUSCH,b,f,c (1), which provides the index P0-PUSCH-AlphaSetId to the set of active UL BWPb of carrier f serving cell c.

[0313] In this example, for j∈{2,...,J-1}=S J , P O_NOMINAL_PUSCH,f,c (j) value (applicable to all j∈S J ) may be provided by p0-NominalWithGrant, or P if p0-NominalWithGrant is not provided O_NOMINAL_PUSCH,f,c (j) = P O_NOMINAL_PUSCH,f,c (0), for each carrier f serving cell c, and P O_UE_PUSCH,b,f,c (j) The set of values ​​is provided by the set of p0 in P0-PUSCH-AlphaSet indicated by the corresponding set of p0-PUSCH-AlphaSetId for the active UL BWPb of carrier f serving cell c.

[0314] In an example, if the wireless device is provided with more than one p0-PUSCH-AlphaSetId value by SRI-PUSCH-PowerControl, and if DCI format 0_1 ​​includes an SRI field, the wireless device may obtain a mapping of sri-PUSCH-PowerControlId in SRI-PUSCH-PowerControl between a set of values ​​of the SRI field from DCI format 0_1 ​​and a set of indices mapped to a set of P0-PUSCH-AlphaSet values ​​provided by p0-PUSCH-AlphaSetId. If a PUSCH transmission is scheduled by DCI format 0_1 ​​including an SRI field, the wireless device determines the P0-PUSCH-AlphaSetId from the p0-PUSCH-AlphaSetId values ​​mapped to the SRI field values. O_UE_PUSCH,b,f,c The value of (j).

[0315] If the PUSCH transmission is scheduled by DCI format 0_0 or DCI format 0_1 ​​that does not include the SRI field, or if SRI-PUSCHPowerControl is not provided to the UE, j=2, the wireless device determines P according to the value of the first p0-Pusch-AlphaSet in p0-AlphaSets. O_UE_PUSCH,b,f,c (j).

[0316] For α b,f,c (j), where j = 0, α b,f,c (0) may be the value of msg3-Alpha (when provided), otherwise the wireless device may determine α b,f,c (0) = 1. For α b,f,c (j), where j = 1, α b,f,c (1) can be provided by alpha obtained from p0-PUSCH-Alpha in ConfiguredGrantConfig, which provides the index P0-PUSCH-AlphaSetId to the set of active UL BWPb of carrier f serving cell c. b,f,c (j), where j∈S J , α b,f,c (j) The value set may be provided by the set of alphas in P0-PUSCH-AlphaSet indicated by the corresponding set of p0-PUSCH-AlphaSetId for the active UL BWPb of carrier f serving cell c.

[0317] For example, if the wireless device is provided with more than one value of SRI-PUSCH-PowerControl and p0-PUSCH-AlphaSetId, and if DCI format 0_1 ​​includes an SRI field, the wireless device may obtain a mapping of sri-PUSCH-PowerControlId in SRI-PUSCH-PowerControl between a set of values ​​of the SRI field from DCI format 0_1 ​​and a set of indices provided by p0-PUSCH-AlphaSetId mapped to a set of P0-PUSCH-AlphaSet values. If a PUSCH transmission is scheduled by DCI format 0_1 ​​including an SRI field, the wireless device may determine the alpha value from the p0-PUSCH-AlphaSetId value mapped to the SRI field value. b,f,c The value of (j).

[0318] For example, if the PUSCH transmission is scheduled by DCI format 0_0 or DCI format 0_1 ​​that does not include the SRI field, or if SRI-PUSCH-PowerControl is not provided to the UE, j=2, the wireless device may determine α according to the value of the first p0-PUSCH-AlphaSet in p0-AlphaSets. b,f,c (j).

[0319] For example, may be the bandwidth of the PUSCH resource assignment expressed in number of resource blocks for PUSCH transmission opportunity i on active UL BWPb of carrier f serving cell c, and μ is the SCS configuration.

[0320] For example, PL b,f,c (q d ) may be the reference signal (RS) index q of the active DL BWP of serving cell c used by the wireless device d The calculated downlink path loss estimate in dB.

[0321] For example, if the wireless device is not provided with PUSCH-PathlossReferenceRS or before the wireless device is provided with dedicated higher layer parameters, the wireless device may use RS resources from the SS / PBCH block (from which the wireless device can obtain the MIB) to calculate PL b,f,c (q d ).

[0322] For example, if the wireless device is configured with a number of RS resource indices, up to the value of maxNrofPUSCH-PathlossReferenceRSs, and a corresponding set of RS configurations of the number of RS resource indices through PUSCH-PathlossReferenceRS, the set of RS resource indices may include: one or both of a set of SS / PBCH block indices, each of which is provided by ssb-Index (when the value of the corresponding pusch-PathlossReferenceRS-Id is mapped to the SS / PBCH block index); and a set of CSI-RS resource indices, each of which is provided by csi-RS-Index (when the value of the corresponding pusch-PathlossReferenceRS-Id is mapped to the CSI-RS resource index). The wireless device may identify the RS resource index q in the set of RS resource indices d , to correspond to the SS / PBCH block index, or to the CSI-RS resource index provided by pusch-PathlossReferenceRS-Id in PUSCH-PathlossReferenceRS.

[0323] For example, if a PUSCH transmission is scheduled by a RAR UL grant, the wireless device may use the same RS resource index q as used for the corresponding PRACH transmission. d .

[0324] For example, if the wireless device is provided with SRI-PUSCH-PowerControl and more than one PUSCH-PathlossReferenceRS-Id value, the wireless device may obtain a mapping of sri-PUSCH-PowerControlId in SRI-PUSCH-PowerControl between a value set of the SRI field from DCI format 0_1 ​​and a value set of PUSCH-PathlossReferenceRS-Id. If a PUSCH transmission is scheduled by DCI format 0_1 ​​including an SRI field, the wireless device may determine the RS resource index q according to the value of PUSCH-PathlossReferenceRS-Id. d , which is mapped to the SRI field value, where the RS resources are on the serving cell c or provided on the serving cell indicated by the value of pathlossReferenceLinking.

[0325] For example, if a PUSCH transmission is scheduled by DCI format 0_0, and if the wireless device is provided with a spatial setting by PUCCH-Spatialrelationinfo for the PUCCH resource with the lowest index of active UL BWPb for each carrier f and serving cell, the wireless device uses the same RS resource index q as for the PUCCH transmission in the PUCCH resource with the lowest index. d .

[0326] For example, if the PUSCH transmission is scheduled by DCI format 0_0 and if the wireless device is not provided with a spatial setting for PUCCH transmission, or is scheduled by DCI format 0_1 ​​that does not include an SRI field, or if SRI-PUSCH-PowerControl is not provided to the wireless device, the wireless device determines the RS resource index q d , where the corresponding PUSCH-PathlossReferenceRS-Id value is equal to zero, where the RS resource is in serving cell c, or if provided, on the serving cell indicated by the value of pathlossReferenceLinking.

[0327] For PUSCH transmissions configured by ConfiguredGrantConfig, if rrc-ConfiguredUplinkGrant is included in ConfiguredGrantConfig, the RS resource index q d It may be provided by the value of pathlossReferenceIndex included in rrc-ConfiguredUplinkGrant, where the RS resource may be on the serving cell c, or if provided, on the serving cell indicated by the value of pathlossReferenceLinking.

[0328] For a PUSCH transmission configured by ConfiguredGrantConfig that does not include rrc-ConfiguredUplinkGrant, the wireless device may determine the RS resource index q based on the value of PUSCH-PathlossReferenceRS-Id mapped to the SRI field value of the DCI format that activates the PUSCH transmission. d For example, if the DCI format activating the PUSCH transmission does not include the SRI field, the wireless device may determine the RS resource index q d, where the corresponding PUSCH-PathlossReferenceRS-Id value is equal to zero, where the RS resource is on the serving cell c, or if provided, on the serving cell indicated by the value of pathlossReferenceLinking.

[0329] The wireless device can determine the PL f,c (q d )=referenceSignalPower—higher layer filtered RSRP, where referenceSignalPower may be provided by higher layers, and the calculation of RSRP may be predefined for a reference serving cell, and the higher layer filter configuration provided by QuantityConfig is for the reference serving cell.

[0330] For example, if the wireless device is not configured for periodic CSI-RS reception, referenceSignalPower is provided by ss-PBCH-BlockPower. For example, if the wireless device is configured for periodic CSI-RS reception, referenceSignalPower is provided by ss-PBCH-BlockPower, or by powerControlOffsetSS which provides a CSI-RS transmission power offset relative to the SS / PBCH block transmission power. For example, if powerControlOffsetSS is not provided to the wireless device, the wireless device may determine an offset of 0 dB.

[0331] The wireless device can determine For K S =1.25 and Δ TF,b,f,c (i) = 0 for K S =0, where K S Each UL BWPb for each carrier f and serving cell c can be provided by deltaMCS. If PUSCH is passed through more than one layer, Δ TF,b,f,c (i) = 0.BPRE and The active UL BWPb for each carrier f and each serving cell c can be calculated as follows

[0332] - The wireless device can determine for PUSCH with UL-SCH data and For CSI transmission in PUSCH without UL-SCH data, where

[0333] -c can be the number of code blocks transferred, K r is the size of the code block r, and N REIt can be determined as The number of resource elements, where may be the number of symbols of PUSCH transmission opportunity i on active UL BWPb of carrier f serving cell c, may be the number of subcarriers other than DM-RS subcarriers, and PUSCH symbol j and C, K r The phase tracking RS samples in may be predefined and / or indicated by DCI and / or RRC.

[0334] - The wireless device can determine For example, when the PUSCH includes UL-SCH data and When, for example, the PUSCH includes CSI and does not include UL-SCH data.

[0335] -Q m may be the modulation order and R is the target code rate, which is provided by the DCI format scheduling PUSCH transmission including CSI but not UL-SCH data.

[0336] PUSCH power control adjustment state f for active UL BWPb of carrier f of serving cell c in PUSCH transmission opportunity i b,f,c (i,l),δ PUSCH,b,f,c (i, l) may be a transmit power control (TPC) command value included in DCI format 0_0 or DCI format 0_1 ​​for scheduling PUSCH transmission opportunity i on active UL BWPb of carrier f of serving cell c, or co-encoded with other TPC commands in DCI format 2_2 CRC-scrambled by a specific RNTI (e.g., TPC-PUSCH-RNTI). The wireless device may determine l∈{0,1} if the wireless device is configured with twoPUSCH-PC-AdjustmentStates, and l=0 if the wireless device is not configured with twoPUSCH-PC-AdjustmentStates or if the PUSCH transmission is scheduled by a RAR UL grant.

[0337] For PUSCH (re)transmissions configured by ConfiguredGrantConfig, the value of l∈{0,1} may be provided to the wireless device by powerControlLoopToUse. For example, if the wireless device is provided with SRI-PUSCH-PowerControl, the wireless device may obtain a mapping between a set of values ​​of the SRI field of DCI format 0_1 ​​and one or more l values ​​provided by sri-PUSCH-ClosedLoopIndex. For example, if the PUSCH transmission is scheduled by DCI format 0_1 ​​and if DCI format 0_1 ​​includes an SRI field, the wireless device may determine that the l value is mapped to the SRI field value. For example, if the PUSCH transmission is scheduled by DCI format 0_0 or by DCI format 0_1 ​​that does not include an SRI field, or if SRI-PUSCH-PowerControl is not provided to the UE, then l=0. For example, if the wireless device obtains a TPC command from DCI format 2_2 scrambled by TPC-PUSCH-RNTI CRC, the l value may be provided by the Closed Loop Indicator field of DCI format 2_2.

[0338] The wireless device can determine is the active UL BWPb of carrier f of serving cell c and the PUSCH power control adjustment state l for PUSCH transmission opportunity i if the wireless device is not provided with tpc-Accumulation, where δ PUSCH,b,f,c The values ​​are given in a predefined table.

[0339] For example, It can be TPC command value set D i The sum of the TPC command values ​​in the PUSCH power control adjustment state 1 received by the wireless device on the active UL BWPb of the carrier f of the serving cell c before the PUSCH transmission opportunity i-i0 PUSCH (i-i0)-1 symbol and K before PUSCH transmission timing i PUSCH (i) The cardinality C(D) between symbols i ), where i0>0 may be the smallest integer for which the K before the PUSCH transmission opportunity i-i0 PUSCH (i-i0) symbols earlier than K before PUSCH transmission opportunity i PUSCH (i) Symbols.

[0340] For example, if PUSCH transmission is scheduled by DCI format 0_0 or DCI format 0_1, K PUSCH(i) may be the number of symbols of active UL BWPb of carrier f of serving cell c after the last symbol of the corresponding PDCCH opportunity and before the first symbol of the PUSCH transmission.

[0341] For example, if PUSCH transmission is configured by ConfiguredGrantConfig, then K PUSCH (i) It can be K PUSCH,min The number of symbols, which is equal to the number of symbols per time slot The product of the minimum value provided by k2 in PUSCH-ConfigCommon of the active ULBWPb of carrier f serving cell c.

[0342] For example, if the wireless device has reached the maximum power of the active UL BWPb of carrier f of serving cell c at PUSCH transmission opportunity i-i0 and The wireless device can then determine f b,f,c (i,l)=f b,f,c (i-i0,l).

[0343] For example, if the wireless device has reached the minimum power of the active UL BWPb of carrier f of serving cell c at PUSCH transmission opportunity i-i0 and The wireless device can then determine f b,f,c (i,l)=f b,f,c (i-i0,l).

[0344] For example, the wireless device may reset the accumulation of the PUSCH power control adjustment state l for the active UL BWPb of carrier f of serving cell c to f b,f,c (0,l)=0, for example, if the corresponding P O_UE_PUSCH,b,f,c The configuration of the value of (j) is provided by higher layers. For example, the wireless device may reset the accumulation of the PUSCH power control adjustment state l for the active UL BWPb of carrier f of serving cell c to f. b,f,c (0,l)=0, for example, if the corresponding α b,f,c (j) The configuration of the value is provided by higher layers.

[0345] For example, if j>1 and the PUSCH transmission is scheduled by DCI format 0_1 ​​including an SRI field, and the wireless device is provided with a higher SRI-PUSCH-PowerControl, the wireless device can determine the value of l according to the value of j based on the indication of the SRI field for the sri-PUSCH-PowerControlId value associated with the sri-P0-PUSCH-AlphaSetId value corresponding to j and the sri-PUSCH-ClosedLoopIndex value corresponding to l.

[0346] For example, if j>1 and the PUSCH transmission is scheduled by DCI format 0_0 or by DCI format 0_1 ​​that does not include the SRI field or the wireless device is not provided with SRI-PUSCH-PowerControl, the wireless device may determine that / =0.

[0347] For example, if j=1, l is provided by the value of powerControlLoopToUse, then the wireless device may determine f b,f,c (i,l)=δ PUSCH,b,f,c (i,l) is the PUSCH power control adjustment state of the active UL BWPb for carrier f and PUSCH transmission opportunity i of serving cell c, if the wireless device is provided with tpc-Accumulation, where δ PUSCH,b,f,c The absolute value can be predefined.

[0348] For example, if the wireless device receives a random access response message in response to a PRACH transmission on an active UL BWPb of carrier f of serving cell c, the wireless device may determine that f b,f,c (0,l)=ΔP rampup,b,f,c +δ msg2,b,f,c , where the wireless device can determine that l = 0 and δ msg2,b,f,c is the TPC command value indicated in the random access response grant of the random access response message corresponding to the PRACH transmission on the active UL BWPb of carrier f in serving cell c, and

[0349] And ΔP rampuprequested,b,f,c provided by higher layers and corresponding to the total power ramp requested by higher layers from the first random access preamble to the last random access preamble of carrier f in serving cell c, is the bandwidth of the PUSCH resource assignment expressed in a number of resource blocks for the first PUSCH transmission on the active UL BWPb of carrier f serving cell c, and Δ TF,b,f,c(0) is the power adjustment for the first PUSCH transmission on the active UL BWP b of carrier f serving cell c.

[0350] For example, if the wireless device transmits a PUCCH using a PUCCH power control adjustment state with index 1 on an active UL BWPb of carrier f in primary cell c, the wireless device determines the PUCCH transmission power P in PUCCH transmission opportunity i. PUCCH,b,f,c (i,q u ,q d ,l) is

[0351]

[0352] For example, P CMAX,f,c (i) may be the configured wireless device transmission power defined in carrier f of serving cell c in PUCCH transmission opportunity i. For example, P O_PUCCH,b,f,c (q u ) can be a parameter consisting of the sum of the following components: O_NOMINAL_PUCCH , by p0-nominal or P O_NOMINAL_PUCCH = 0 dBm (if p0-nominal is not provided) provided, carrier f for primary cell c; and, if provided, component P O_UE_PUCCH (q u ), which is provided by the p0-PUCCH-Value in the P0-PUCCH of the active ULBWPb of carrier f of primary cell c, where 0≤q u u .Q u It can be P provided by maxNrofPUCCH-P0-PerSet O_UE_PUCCH The size of the value set. O_UE_PUCCH The value set may be provided by p0-Set. If p0-Set is not provided to the wireless device, the wireless device may determine P O_UE_PUCCH (q u )=0,0≤q u u .

[0353] ​​For example, if the wireless device is provided with PUCCH-SpatialRelationInfo, the wireless device may obtain a mapping between a set of pucch-SpatialRelationInfoId values ​​and a set of p0-PUCCH-Value values ​​through an index provided by p0-PUCCH-Id. If the wireless device is provided with more than one pucch-SpatialRelationInfoId value, and the wireless device receives an activation command indicating a value of pucch-SpatialRelationInfoId, the wireless device may determine the p0-PUCCH-Value value through a link with the corresponding p0-PUCCH-Id index. The wireless device may apply an activation command with a time offset (e.g., 3 milliseconds) after the time slot in which the wireless device transmits HARQ-ACK information of the PDSCH providing the activation command. For example, if PUCCH-SpatialRelationInfo is not provided to the wireless device, the wireless device may obtain the p0-PUCCH-Value value from the P0-PUCCH with a 0-PUCCH-Id value equal to 0 in the p0-Set.

[0354] For example, may be the bandwidth of the PUCCH resource assignment expressed in a number of resource blocks for PUCCH transmission opportunity i on the active UL BWPb of carrier f of serving cell c, and μ is the SCS configuration.

[0355] For example, PL b,f,c (q d ) can be a RS resource index q used by the wireless device d The calculated downlink path loss estimate in dB as described elsewhere in this specification for the active DLBWP of carrier f of primary cell c.

[0356] For example, if the wireless device is not provided with pathlossReferenceRSs or before the wireless device is provided with dedicated higher layer parameters, the wireless device may determine the PL using RS resources obtained from the SS / PBCH blocks that the wireless device uses to obtain the MIB. b,f,c (q d ).

[0357] For example, if the wireless device is provided with several RS resource indexes, the wireless device may use the RS resource index with index q d RS resources determine PL b,f,c (q d ), where 0≤q d d .Q d ​It can be the size of the RS resource set provided by maxNrofPUCCH-PathlossReferenceRSs. The RS resource set can be provided by patlossReferenceRS. The RS resource set may include one or both of the following: a set of SS / PBCH block indices, each of which is provided by ssb-Index in PUCCH-PathlossReferenceRS when the value of the corresponding pucch-PathlossReferenceRS-Id is mapped to the SS / PBCH block index; and a set of CSI-RS resource indices, each of which is provided by csi-RS-Index when the value of the corresponding pucch-PathlossReferenceRS-Id is mapped to the CSI-RS resource index. The wireless device can identify the RS resources in the RS resource set to correspond to the SS / PBCH block index or to the CSI-RS resource index provided by the pucch-PathlossReferenceRS-Id in the PUCCH-PathlossReferenceRS.

[0358] For example, if the wireless device is provided with PUCCH-SpatialRelationInfo, the wireless device may obtain a mapping between a set of pucch-SpatialRelationInfoId values ​​and a set of reference signal values ​​provided by PUCCH-PathlossReferenceRS through an index provided by a corresponding value of pucch-PathlossReferenceRS-Id. If the wireless device is provided with more than one value of pucch-SpatialRelationInfoId, and the wireless device receives an activation command indicating a value of pucch-SpatialRelationInfoId, the wireless device may determine the reference signal value in PUCCH-PathlossReferenceRS through a link with the corresponding pucch-PathlossReferenceRS-Id index. The wireless device may apply an activation command with a time offset (e.g., 3 milliseconds) after a time slot in which the wireless device transmits HARQ-ACK information of a PDSCH providing the activation command.

[0359] For example, if PUCCH-SpatialRelationInfo includes servingCellId indicating a serving cell, the wireless device may receive the resource index q on the active DL BWP of the serving cell. dFor example, if the wireless device is not provided with PUCCH-SpatialRelationInfo, the wireless device may obtain the reference signal value in PUCCH-PathlossReferenceRS from the pucch-PathlossReferenceRS-Id with index 0 in PUCCH-PathlossReferenceRS, where the RS resource is on the same serving cell, or if provided, on the serving cell indicated by the value of pathlossReferenceLinking.

[0360] For example, the parameter Δ F_PUCCH (F) can be provided by deltaF-PUCCH-f0 of PUCCH format 0, deltaF-PUCCH-f1 of PUCCH format 1, deltaF-PUCCH-f2 of PUCCH format 2, deltaF-PUCCH-f3 of PUCCH format 3 and deltaF-PUCCH-f4 of PUCCH format 4.

[0361] For example, Δ TF,b,f,c (i) The PUCCH transmission power adjustment component on the active UL BWPb of carrier f may be primary cell c. For PUCCH transmission using PUCCH format 0 or PUCCH format 1, the wireless device may determine

[0362] For example, The number of PUCCH format 0 symbols or PUCCH format 1 symbols included in the PUCCH resources of the PUCCH resource set indicated by the value of the PUCCH resource indicator field of DCI format 1_0 or DCI format 1_1 or provided by nrofSymbols of PUCCH-format0 or PUCCH-format1, respectively. For example, the wireless device may determine the number of PUCCH format 0 symbols or PUCCH format 1 symbols. For example, the wireless device may determine the PUCCH format 1 For example, the wireless device may determine the Δ UCI (i) = 0. For example, the wireless device may determine Δ UCI (i) = 10log 10 (O UCI (i)), where O UCI (i) may be the number of UCI bits in PUCCH transmission opportunity i.

[0363] For PUCCH transmissions using PUCCH format 2 or PUCCH format 3 or PUCCH format 4, and for a number of UCI bits less than or equal to 11, the wireless device may determine Δ TF,b,f,c (i) = 10log 10 (K1·(n HARQ-ACK (i)+O SR (i)+O CSI (i)) / N RE (i)). For example, K1 = 6. For example, n HARQ-ACK (i) may be the number of HARQ-ACK information bits determined by the wireless device for the Type-1 HARQ-ACK codebook and the Type-2 HARQ-ACK codebook. If the wireless device is not equipped with a pdsch-HARQ-ACK-Codebook, the wireless device may determine n HARQ-ACK (i) = 1, if the wireless device includes HARQ-ACK information bits in the PUCCH transmission; otherwise, the wireless device may determine n HARQ-ACK (i)=0.

[0364] For example, O SR (i) may be the number of SR information bits determined by the wireless device. CSI (i) may be the number of CSI information bits determined by the wireless device.

[0365] For example, N RE (i) may be determined as The number of resource elements, where may be the number of subcarriers per resource block excluding the subcarriers used for DM-RS transmission, and is the number of symbols excluding symbols used for DM-RS transmission for PUCCH transmission opportunity i on active UL BWPb of carrier f serving cell c.

[0366] For PUCCH transmissions using PUCCH format 2 or PUCCH format 3 or PUCCH format 4, and for a number of UCI bits greater than 11, the wireless device may determine

[0367] For example, K2=2.4. For example, the wireless device may determine BPRE(i)=(O ACK (i)+O SR (i)+O CSI (i)+O CRC (i)) / N RE (i).

[0368] For example, O ACK(i) may be the number of HARQ-ACK information bits determined by the wireless device for the Type-1 HARQ-ACK codebook and the Type-2 HARQ-ACK codebook. If the wireless device is not provided with the pdsch-HARQ-ACK-Codebook, the wireless device may determine ACK = 1, if the wireless device includes HARQ-ACK information bits in the PUCCH transmission; otherwise, ACK =0.

[0369] For example, O SR (i) may be the number of SR information bits determined by the wireless device. CSI (i) may be the number of CSI information bits determined by the wireless device. CRC (i) can be the number of CRC bits.

[0370] For example, N RE (i) It may be possible for the wireless device to be determined as The number of resource elements, where may be the number of subcarriers per resource block excluding the subcarriers used for DM-RS transmission, and It can be the number of symbols of PUCCH transmission opportunity i on active UL BWPb of carrier f for serving cell c excluding symbols used for DM-RS transmission.

[0371] Active UL BWPb for carrier f of primary cell c and PUCCH power control adjustment state g for PUCCH transmission opportunity i b,f,c (i, l), the wireless device may determine at least one of the following.

[0372] For example, δ PUCCH,b,f,c (i,l) can be a TPC command value and included in DCI format 1_0 or DCI format 1_1 for the active UL BWPb of carrier f of primary cell c, which can be detected by the wireless device for PUCCH transmission opportunity i or encoded together with other TPC commands in DCI format 2_2 scrambled by a specific RNTI (e.g., TPC-PUCCH-RNTI) CRC.

[0373] For example, l∈{0,1} if the wireless device is provided with twoPUCCH-PC-AdjustmentStates and PUCCH-SpatialRelationInfo, and l=0 if the wireless device is not provided with twoPUCCH-PC-AdjustmentStates or PUCCH-SpatialRelationInfo.

[0374] For example, if the wireless device obtains a TPC command value from DCI format 1_0 or DCI format 1_1, and if the wireless device is provided with PUCCH-SpatialRelationInfo, the wireless device may obtain a mapping between a pucch-SpatialRelationInfoId value set and a closedLoopIndex value set providing one or more l values ​​through an index provided by p0-PUCCH-Id. If the wireless device receives an activation command indicating a value of pucch-SpatialRelationInfoId, the wireless device may determine a value of closedLoopIndex providing a value of l through a linkage with a corresponding p0-PUCCH-Id index.

[0375] For example, if the wireless device obtains a TPC command from DCI format 2_2 CRC-scrambled by a specific RNTI (e.g., TPC-PUCCH-RNTI), and the value of l is provided by the closed loop indicator field of DCI format 2_2, the wireless device may determine is the active ULBWPb of carrier f in serving cell c and the current PUCCH power control adjustment state l for PUCCH transmission opportunity i, where δ PUCCH,b,f,c The value can be predefined.

[0376] For example, It can be a set C of TPC command values i The sum of the TPC command values ​​in the PUCCH power control adjustment state received by the wireless device on the active ULBWPb of the carrier f of the serving cell c before the PUCCH transmission opportunity i-i0 PUCCH (i-i0)-1 symbol and K before PUCCH transmission timing i PUCCH (i) The cardinality C between symbols (C i ), where i0>0 may be the smallest integer for which the K before the PUCCH transmission opportunity i-i0 PUCCH (i-i0) symbols earlier than the K of PUCCH transmission opportunity i PUCCH (i) Symbols.

[0377] For example, if the PUCCH transmission is in response to the wireless device detecting DCI format 1_0 or DCI format 1_1, then K PUCCH (i) may be the number of symbols of active UL BWPb for carrier f of serving cell c after the last symbol of the corresponding PDCCH reception and before the first symbol of PUCCH transmission.

[0378] For example, if the PUCCH transmission is not in response to detection of DCI format 1_0 or DCI format 1_1 by the wireless device, then K PUCCH (i) It can be K PUCCH,min The number of symbols, which is equal to the number of symbols per time slot The product of the minimum value provided by k2 in PUSCH-ConfigCommon for the active UL BWPb of carrier f serving cell c.

[0379] For example, if the wireless device has reached the maximum power of the active UL BWPb of carrier f of primary cell c at PUCCH transmission opportunity i-i0 and The wireless device can then determine g b,f,c (i,l)=g b,f,c (i-i0,l).

[0380] For example, if the wireless device has reached the minimum power of the active UL BWPb of carrier f of primary cell c at PUCCH transmission opportunity i-i0 and The wireless device can then determine g b,f,c (i,l)=g b,f,c (i-i0,l).

[0381] For example, if the PUCCH power control adjustment state 1 of the active UL BWPb of carrier f of serving cell c is O_PUCCH,b,f,c (q u ) value is provided by a higher layer, the wireless device can determine g b,f,c (0, l) = 0. For example, if the wireless device is provided with PUCCH-SpatialRelationInfo, the wireless device may u The p0-PUCCH-Id value associated with the closedLoopIndex value corresponding to l is associated with the pucch-SpatialRelationInfoId value associated with q u The value of determines the value of l; otherwise, l=0.

[0382] For example, if the PUCCH power control adjustment state 1 of the active UL BWPb of carrier f of serving cell c is O_PUCCH,b,f,c (q u ) value is not provided by a higher layer, the wireless device may determine b,f,c (0,l)=ΔP rampup,b,f,c +δ b,f,c For example, l = 0, and δ b,f,cmay be a TPC command value indicated in a random access response grant corresponding to a PRACH transmission, or a TPC command value in a DCI format scrambled by a specific RNTI (e.g., C-RNTI or MCS-C-RNTI) CRC detected by the wireless device in the first PDCCH reception in the search space set provided by recoverySearchSpaceId, if the PUCCH transmission is the first PUCCH transmission after a number of symbols (e.g., 28 symbols) from the first symbol of the first PDCCH reception, and if the wireless device transmits a PUCCH on an active UL BWPb of carrier f of serving cell c, then the wireless device may determine Otherwise, the wireless device can Where ΔP rampuprequested,b,f,c may be provided by higher layers and corresponds to the total power ramp requested by higher layers from the first preamble to the last preamble of the active UL BWPb of carrier f of primary cell c, and Δ F_PUCCH (F) corresponds to PUCCH format 0 or PUCCH format 1.

[0383] If the wireless device transmits SRS on the active UL BWPb of carrier f of serving cell c using the SRS power control adjustment state with index l, the wireless device may determine the SRS opportunity power P in SRS transmission opportunity i. SRS,b,f,c (i,q s ,l) is

[0384]

[0385] For example, P CMAX,f,c (i) may be the configured wireless device transmission power of carrier f of serving cell c in SRS transmission opportunity i. For example, P O_SRS,b,f,c (q s ) can be provided by p0 of the active UL BWPb of carrier f of serving cell c, and SRS resource set q s Provided by SRS-ResourceSet and SRS-ResourceSetId; if p0 is not provided, P O_SRS,b,f,c (q s )=P O_NOMINAL_PUSCH,f,c (0). For example, M SRS,b,f,c (i) may be the SRS bandwidth expressed in a number of resource blocks for SRS transmission opportunity i on the active UL BWPb of carrier f of serving cell c, and μ is the SCS configuration. SRS,b,f,c (q s ) can be composed of the alpha and SRS resource set q of the active UL BWPb of carrier f of serving cell c s supply.

[0386] For example, PL b,f,c (q d ) can be a RS resource index q used by the wireless device d The downlink path loss estimate in dB calculated, as described elsewhere in this specification, for the active DL BWP and SRS resource set q for serving cell c s RS resource index q d Can be composed by SRS resource set q s The associated pathlossReferenceRS is provided and can be either ssb-Index providing the SS / PBCH block index or csi-RS-Index providing the CSI-RS resource index.

[0387] For example, if the wireless device is not provided with pathlossReferenceRS or a dedicated higher layer parameter is provided before the wireless device, the wireless device may determine PL using RS resources obtained from the SS / PBCH block that the wireless device uses to obtain the MIB. b,f,c (q d ). For example, if the wireless device is provided with pathlossReferenceLinking, the RS resource can be on the serving cell indicated by the value of pathlossReferenceLinking.

[0388] For example, the wireless device may determine h b,f,c (i,l)=f b,f,c (i,l), where f b,f,c (i, l) may be the current PUSCH power control adjustment state, for example, if srs-PowerControlAdjustmentStates indicates the same power control adjustment state for SRS transmission and PUSCH transmission.

[0389] For example, the wireless device may determine For example, if the wireless device is not configured for PUSCH transmission on the active UL BWPb of carrier f serving cell c, or if srs-PowerControlAdjustmentStates indicates separate power control adjustment between SRS transmission and PUSCH transmission, and if tpc-Accumulation is not provided, where δ SRS,b,f,c The value can be predefined.

[0390] For example, δ SRS,b,f,c (m) can be encoded together with other TPC commands in PDCCH with DCI format 2_3. For example, It can be a set of TPC command values ​​S i The sum of the TPC command values ​​in K before SRS transmission opportunity i-i0 on the active UL BWPb of carrier f of serving cell c with SRS power control adjustment state received by the wireless device SRS (i-i0)-1 symbol and K before SRS transmission timing i SRS (i) The cardinality C(S) between symbols i ), where i0>0 may be the smallest integer for which the K before the SRS transmission opportunity i-i0 SRS (i-i0) symbols earlier than K before SRS transmission opportunity i SRS (i) Symbols.

[0391] For example, if SRS transmission is aperiodic, then K SRS (i) may be the number of symbols of active ULBWPb of carrier f of serving cell c after the last symbol of the corresponding PDCCH triggering SRS transmission and before the first symbol of SRS transmission.

[0392] For example, if the SRS transmission is semi-persistent or periodic, then K SRS (i) It can be K SRS,min The number of symbols, which is equal to the number of symbols per time slot The product of the minimum value provided by k2 in PUSCH-ConfigCommon for the active UL BWPb of carrier f serving cell c.

[0393] For example, if the wireless device has reached the maximum power of the active UL BWPb of carrier f of serving cell c at SRS transmission opportunity i-i0 and The wireless device can then determine h b,f,c (i) = h b,f,c For example, if the wireless device has reached the minimum power of the active ULBWPb of carrier f of serving cell c at SRS transmission opportunity i-i0 and The wireless device can then determine h b,f,c (i) = h b,f,c (i-i0).

[0394] For example, if the SRS power control adjustment state l corresponding to the active UL BWPb of carrier f of serving cell c is P O_SRS,b,f,c (q s ) value or α SRS,b,f,c (q s ) value is provided by a higher layer, the wireless device can determine b,f,c(0) = 0; otherwise the wireless device can determine h b,f,c (0) = ΔP ranpup,b,f,c +δ msg2,b,f,c .

[0395] For example, δ msg2,b,f,c may be the TPC command value indicated in a random access response grant corresponding to a random access preamble transmitted by the wireless device on the active UL BWPb of carrier f of serving cell c, and

[0396]

[0397] For example, ΔP rampuprequ ested,b,f,c It may be provided by higher layers and corresponds to the total power ramp requested by higher layers from the first preamble to the last preamble of active UL BWPb for carrier f serving cell c.

[0398] For example, the wireless device may determine h b,f,c (i) = δ SRS,b,f,c (i) If the wireless device is not configured for PUSCH transmission on the active UL BWPb of carrier f serving cell c, or if srs-PowerControlAdjustmentStates indicates separate power control adjustment states between SRS transmission and PUSCH transmission, and tpc-Accumulation is provided, and the wireless device can detect DCI format 2_3K before the first symbol of SRS transmission opportunity i SRS,min Symbol, where δ SRS,b,f,c The absolute value of can be predefined.

[0399] For example, if srs-PowerControlAdjustmentStates indicates the same power control adjustment state for SRS transmission and PUSCH transmission, then the update of the power control adjustment state for SRS transmission opportunity i may occur at SRS resource set q. s Otherwise, the update of the power control adjustment state of SRS transmission opportunity i may occur at the beginning of each SRS resource set q. s The beginning of the first transmitted SRS resource in .

[0400] When one or more uplink signals / channels partially or completely overlap in the time domain, the wireless device may allocate / determine one or more transmission powers of the one or more uplink signals / channels based on a priority rule. When the calculated transmission power exceeds the maximum allowed transmission power of the wireless device, the wireless device may implement a priority rule to reduce (adjust) or reduce one or more signals. For example, the priority rule may determine a higher priority for a first uplink signal / channel of the one or more uplink signals / channels and a lower priority for a second uplink signal / channel of the one or more uplink signals / channels. The wireless device may adjust the transmission power or reduce the second uplink signal / channel.

[0401] In the prior art, power priority rules are implemented between PRACH, PUSCH, PUCCH and SRS to reduce or lower the power of one or more channels when the UE is power limited. For example, the wireless device may prioritize PRACH over PUCCH and / or PUSCH. For example, the wireless device may prioritize PUCCH over PUSCH. In the prior art, a wireless device may support multiple services via a base station. For example, the wireless device may receive / transmit one or more first channels / signals associated with a first service. The wireless device may receive / transmit one or more second channels / signals associated with a second service. For example, the first service may be ultra-reliable low latency communication (URLLC). For example, the second service may be enhanced mobile broadband (eMBB). Based on the prior art, the wireless device may prioritize the first PUSCH including URLLC over the PUSCH including eMBB. Prioritizing PRACH over PUSCH may result in a decrease in the QoS experience of some PUSCH services. In an example of the prior art, the wireless device may prioritize PUCCH with a high priority over PRACH. Since the wireless device may transmit PRACH in situations where a recovery type is required (e.g., recovering uplink synchronization, recovering beam failure, recovering connection, etc.), lowering or reducing the transmission power on PRACH may result in longer recovery latency. This may result in performance degradation.

[0402] Various power priority rules for uplink channels in the prior art may lead to a degradation in the QoS experience of PUSCH, PUCCH and PRACH services and procedures, for example, when PRACH is transmitted on multiple cells and uplink channels (PUSCH and / or PUSCH) on one or more cells carry information with different priority levels. Implementing the prior art priority rules may lead to increased packet loss, transmission delays and increased battery power consumption. The prior art may not be able to effectively resolve the priority rules between multiple uplink channels.

[0403] In an example, an embodiment enhances the priority rules of the multiple uplink channels to improve the QoS experience for PUSCH, PUCCH and PRACH services and procedures. The enhanced priority rules take into account that the first uplink channel can be associated with a high priority / first service, and the second uplink channel can be associated with a low priority (e.g., a second service, no priority level). For example, the order may be as follows: PRACH of the primary cell, an uplink channel including first information with a first priority, an uplink channel including second information with a second priority, and then PRACH on the secondary cell (SCell). The enhanced priority rules take into account channels including data with different priority levels, as well as PRACH on the primary cell and PRACH on the secondary cell. Both information with high priority and information with low priority have a higher power priority than PRACH on SCell. Both information with high priority and information with low priority have a lower power priority than PRACH on PCell. An exemplary embodiment may provide such an enhancement that takes into account that PRACH on PCell and PRACH on SCell can be transmitted in parallel with high priority information and low priority information. Implementation of enhanced power priority rules may result in reduced packet loss, reduced transmission delay, and reduced battery power consumption. For example, implementation of enhanced power priority rules may improve uplink recovery of connections by prioritizing PRACH on PCell. For example, implementation of enhanced priority rules improves uplink data / control transmission of high / low priority information by assigning a lower priority to PRACH on SCell compared to uplink data / control transmission of high / low priority information.

[0404] In exiting the dual connection system, the first base station (e.g., MCG) of the first cell group and / or the second base station (e.g., SCG) of the second cell group may configure a first transmission power threshold for the first cell group and a second transmission power threshold for the second cell group. The first transmission power threshold and the second transmission power threshold may not exceed the UE allowed power determined based on the UE power category. The wireless device may allocate power to one or more first uplink channels of the first base station, wherein the sum of the allocated power of the first cell group may be equal to or less than the first power threshold. The wireless device may allocate power to one or more second uplink channels of the second base station, wherein the sum of the power allocated to the second cell group may be equal to or less than the second power threshold. The wireless device may reduce the UL channel or reduce the power on the UL channel of the cell group (CG) until the sum of the power on the UL channel of the CG is less than or equal to the transmission power threshold (e.g., the first transmission power threshold of the first CG, the second transmission power threshold of the second CG). For example, in certain coverage conditions (e.g., cell edge), the implementation of the prior art may result in power reduction or packet discarding of data packets. In an example, in some scenarios, the CG transmission power can reach the UE allowed transmission power of the CG, while each cell transmits below its maximum / allowed transmission power. For example, when the wireless device reduces the power level of the data packet, the reliability of the data channel is reduced. When the UE is in poor coverage conditions, the existing implementation of CG power allocation (for example, when dual connectivity is configured) may increase the packet loss of data packets. When the UE is dual-connected, for example, when the UE transmits uplink data channels for multiple services, it is necessary to improve the existing power allocation process.

[0405] An exemplary embodiment implements a power allocation process based on one or more QoS requirements of a URLLC service (or other services) and provides efficient power sharing between CGs. An exemplary embodiment provides enhancements to power control when implementing dual connectivity, for example, by providing a more flexible transmission power threshold for uplink transmissions via CGs.

[0406] In an example, the first base station and / or the second base station may transmit one or more RRC messages indicating a first transmission power threshold and a second transmission power threshold of the CG. The one or more RRC messages may include configuration parameters of multiple cells grouped into multiple CGs. The multiple CGs may include a first CG for communication via the first base station. The multiple CGs may include a second CG for communication via the second base station. When one or more conditions are met, the wireless device may allocate the power of the UL channel based on the second transmission power threshold of the CG (e.g., the sum of the powers of the UL channels is less than the second power threshold). When determining whether the one or more conditions are met, the wireless device may select a first UL channel from the UL channels scheduled to be transmitted in the OFDM symbol i of the time slot n of the CG, wherein the first UL channel has the highest order (e.g., based on the sorting rule, the first UL has the highest priority in the UL channel). For example, the sorting rule may be based on the UCI content transmitted via the UL channel (e.g., PRACH>HARQ-ACK feedback>CSI>data>SRS) and / or the priority category associated with the UL channel (e.g., URLLC channel>eMBB channel). Based on the selection, the one or more conditions may be determined based on the transmission power of the first UL channel and the priority category of the first UL channel. For example, when the first UL channel is associated with a URLLC service or is associated with a priority category corresponding to a high priority, and the transmission power of the first UL channel is greater than the first power threshold based on a power determination procedure (e.g., based on one or more power control parameters, path loss, a transmission power threshold of a cell where an uplink occurs), the wireless device may apply a second transmission power threshold.

[0407] An exemplary embodiment efficiently allocates transmission power to the URLLC uplink channel of the first CG while reducing the impact on the second CG. The performance of the URLLC uplink channel can be improved while maintaining fair power sharing between CGs.

[0408] In the exit dual connection system, the first base station (e.g., MCG) of the first cell group and / or the second base station (e.g., SCG) of the second cell group may configure the first transmission power threshold of the first cell group and the second transmission power threshold of the second cell group. The first transmission power threshold and the second transmission power threshold may not exceed the UE allowed power determined based on the UE power category. The wireless device may allocate power to one or more first uplink channels of the first base station, wherein the sum of the allocated power of the first cell group may be equal to or less than the first power threshold. The wireless device may allocate power to one or more second uplink channels of the second base station, wherein the sum of the power allocated to the second cell group may be equal to or less than the second power threshold. The wireless device may reduce the UL channel or reduce the power on the UL channel of the cell group (CG) until the sum of the power on the UL channel of the CG is less than or equal to the transmission power threshold (e.g., the first transmission power threshold of the first CG, the second transmission power threshold of the second CG). The implementation of the prior art of using different common and / or dedicated power control parameters of cells based on channel and / or service type (e.g., configuring power control parameters of multiple maximum transmission powers of each cell based on channel priority) may not reduce the packet loss rate of URLLC and high priority data. For example, under certain coverage conditions (e.g., cell edge), power reduction or packet discards of one or more URLLC packets may increase. In an example, in some scenarios, the CG transmission power may reach the UE allowed transmission power of the CG, while each cell transmission is lower than its maximum / allowed transmission power. For example, when the wireless device reduces the power level of the URLLC uplink channel, the reliability of the URLLC uplink channel may decrease. Existing implementations of CG power allocation (e.g., when dual connectivity is configured) may increase packet loss of URLCC packets and other high priority packets.

[0409] An exemplary embodiment implements a power allocation process based on one or more QoS requirements of a URLLC service (or other services) and provides efficient power sharing between CGs. An exemplary embodiment provides enhancements to power control when implementing dual connectivity, for example, by providing a more flexible transmission power threshold for uplink transmissions via CGs.

[0410] In an example, the first base station and / or the second base station may transmit one or more RRC messages indicating a first transmission power threshold and a second transmission power threshold of the CG. The one or more RRC messages may include configuration parameters of multiple cells grouped into multiple CGs. The multiple CGs may include a first CG for communication via the first base station. The multiple CGs may include a second CG for communication via the second base station. When one or more conditions are met, the wireless device may allocate the power of the UL channel based on the second transmission power threshold of the CG (e.g., the sum of the powers of the UL channels is less than the second power threshold). When determining whether the one or more conditions are met, the wireless device may select a first UL channel from the UL channels scheduled to be transmitted in the OFDM symbol i of the time slot n of the CG, wherein the first UL channel has the highest order (e.g., based on the sorting rule, the first UL has the highest priority in the UL channel). For example, the sorting rule may be based on the UCI content transmitted via the UL channel (e.g., PRACH>HARQ-ACK feedback>CSI>data>SRS) and / or the priority category associated with the UL channel (e.g., URLLC channel>eMBB channel). Based on the selection, the one or more conditions may be determined based on the transmission power of the first UL channel and the priority category of the first UL channel. For example, when the first UL channel is associated with a URLLC service or is associated with a priority category corresponding to a high priority, and the transmission power of the first UL channel is greater than the first power threshold based on a power determination procedure (e.g., based on one or more power control parameters, path loss, a transmission power threshold of a cell where an uplink occurs), the wireless device may apply a second transmission power threshold.

[0411] An exemplary embodiment efficiently allocates transmission power to the URLLC uplink channel of the first CG while reducing the impact on the second CG. The performance of the URLLC uplink channel can be improved while maintaining fair power sharing between CGs.

[0412] In an example, the first base station and / or the second base station may transmit one or more RRC messages, the one or more RRC messages including a first transmission power threshold of the first CG and a second transmission power threshold of the second CG. Based on the one or more RRC messages, the wireless device may determine / reserve a first reserved power for the first cell group. For example, the first reserved power for the first cell group may refer to unused / unallocated power for the second cell group. For example, the first reserved power may be determined based on the UE allowed / maximum power and the second transmission power threshold of the second cell group (e.g., UE allowed power-second power threshold). The wireless device may determine the UE allowed / maximum power based on the power category that the wireless device can support for the first cell group. In an example, the wireless device may determine / reserve a second reserved power for the second cell group. The second reserved power may be determined based on the allowed UE / maximum power and the first power threshold of the first cell group.

[0413] The first base station may use the first reserved power to schedule one or more uplink channels that may not be power scaled or reduced due to power limitations. For example, the first reserved power of the first cell group may be ensured regardless of the power allocation to one or more second uplink channels / transmissions of the second cell group. The wireless device may limit the overall / total power of the one or more second uplink channels / transmissions of the second cell group to be equal to or lower than a second transmission power threshold. The second base station may use the second reserved power to schedule one or more uplink channels that may not be power scaled or reduced due to power limitations. The reserved power of the cell group is necessary when scheduling one or more uplink channels with guaranteed / ensured power.

[0414] In order to reserve the reserved power for the second CG, the first transmission power threshold of the first CG may not be equal to the UE allowed power and may be lower than the UE allowed / maximum power. Similarly, the second transmission power threshold of the second CG may not be equal to the UE allowed power and may be lower than the UE allowed / maximum power. Since the transmission power threshold of the CG is less than the UE allowed power, there is a situation where the configured transmission power on the URLLC UL channel of the CG may not be allocated because the configured transmission power may be greater than the transmission power threshold of the CG. Increasing the transmission power threshold may not solve this problem because it may reduce the performance of the power shared between cross-cell groups. In an instance, the reserved power may also be referred to as guaranteed power. In an instance, the UE allowed power may be determined based on the UE maximum power based on the UE power category, or based on the UE internal logic, or based on the regulation requirements, or based on one or more power control parameters. The UE allowed power may be referred to as the UE maximum power.

[0415] In an example, the wireless device may allocate a first power level exceeding a first power threshold (e.g., greater than the first power threshold) for a first cell group (CG) on a first URLLC uplink channel. The wireless device may allocate a second power level exceeding a second power threshold (e.g., greater than the second power threshold) for a second CG on a second URLLC uplink channel. The wireless device may allocate a third power level equal to or less than the first power threshold for the first CG on a third eMBB uplink channel. The wireless device may allocate a fourth power level equal to or less than the second power threshold for the second CG on a fourth eMBB uplink channel.

[0416] Allocating a first power level exceeding a first transmission power threshold may reduce the performance of the second CG when the reserved power of the second CG is reduced. When dealing with potential performance degradation of the first CG due to high-power transmission of URLLC transmission in the second CG, the first base station and / or the second base station may configure a first ratio of the first CG. The first base station and / or the second base station may configure a second ratio of the second CG. The wireless device may use high power exceeding the first transmission power threshold configured for the first CG within the ratio value. The ratio may be determined by the duration of high power use compared to the measurement interval. For example, if the ratio is 5%, the wireless device is not expected to use high power (e.g., greater than the first transmission power threshold in the first CG) for more than 5% of uplink transmission opportunities / opportunities. For example, when the ratio is 5%, the wireless device may be allowed to allocate high power for URLLC transmission of the first CG once in every 20 uplink transmissions. For example, when the ratio is 5%, the wireless device may be allowed to allocate high power for URLLC transmission of the first CG for 5 milliseconds in every 100 millisecond window. For example, when the ratio is 5%, the wireless device may be allowed to allocate high power for URLLC transmission of the first CG once every 20 uplink time slots (or 5 transmissions in every 100 uplink time slots).

[0417] The first base station and / or the second base station may configure / indicate a third transmission power threshold of the first CG. The first base station and / or the second base station may configure / indicate a fourth transmission power threshold of the second CG. The wireless device may allocate a power of a URLLC uplink channel equal to or less than the third power threshold to the first CG. The wireless device may allocate a power of a URLLC uplink channel equal to or less than the fourth threshold to the second CG.

[0418] In the configuration / indication of the threshold, the first base station and / or the second base station may configure the first power allowable value of the first CG. The first base station and / or the second base station may configure the second power allowable value of the second CG. The wireless device may allocate a first power equal to or less than the sum of the first transmission power threshold and the first power allowable value to the first CG on the URLLC UL channel. The wireless device may allocate a second power equal to or less than the sum of the second transmission power threshold and the second power allowable value to the second CG on the URLLC UL channel. For example, the third transmission power threshold of the first CG and / or the fourth transmission power threshold of the second CG may be implicitly determined based on the UE allowed power. For example, when the wireless device may not receive other RRC messages to set the parameters of the third transmission power threshold and / or the fourth power threshold, the third transmission power threshold of the first CG and / or the fourth transmission power threshold of the second CG may be implicitly determined based on the UE allowed power. The embodiment may allow the performance enhancement of the URLLC service to be achieved by increasing the opportunity that the configured power on the URLLC uplink channel can be guaranteed. The embodiment may allow resources to be efficiently shared between cell groups based on the guaranteed power (which is guaranteed at least when no URLLC business is generated). Configuration of the CG with a first transmission power threshold level for a first service (e.g., eMBB service) and a second transmission power threshold level for a second service (e.g., URLLC service) can allow performance enhancement of the second service while reducing the impact on the first service.

[0419] In an example, the first quality of service target of the first service (eg, eMBB) may be different from the second quality of service target of the second service (eg, URLLC). For example, the first quality of service target may be 10 -1 The BLER of the service target can be 10, and the latency requirement is 4 milliseconds. -5 The BLER of the first service and the latency requirement are less than 1 millisecond. The wireless device can operate in a dual connectivity scenario, where a first CG (e.g., MCG) can provide coverage and a second CG (e.g., SCG) can provide throughput or support a second service. When supporting different quality of service targets for the first service and the second service, the uplink power required for the first service and the second service can be different.

[0420] For example, if Fig.16 As shown in , the first uplink power coverage of the first service (eg, the first service power range) may be smaller than the second uplink power coverage of the second service (eg, the second service power range). Fig.16An embodiment is shown. In a dual-connectivity scenario, a wireless device (e.g., UE) may be associated with a first base station (e.g., base station 1) and a second base station (e.g., base station 2). The first base station and the second base station may split the UE allowed power between two cell groups. The first base station and / or the second base station may configure a first threshold for a first service and a second threshold for a second service for a first CG. The first base station and / or the second base station may configure a third threshold for the first service and a fourth threshold for the second service for a second CG. The potential uplink coverage based on the first threshold and the second threshold of the first CG (e.g., base station 1) is shown in the left figure (for the first base station, the first service power range is shown with an inner circle and the second service power range is shown with an outer circle, respectively). The potential uplink coverage based on the third threshold and the fourth threshold of the second base station is shown in the right figure (for the second base station, the first service power range is shown with an inner circle and the second service power range is shown with an outer circle, respectively). For example, the first CG may be configured / associated with the first base station. The second CG may be configured / associated with the second base station. For example, Fig.16 It is shown that the first service power range of the first CG / first base station can be smaller than the second service power range. In response to the uplink of the first CG being associated with a first service / priority (e.g., eMBB service), the wireless device can apply a first allowed power based on a first threshold. In response to the uplink of the first CG being associated with a second service / priority (e.g., URLLC service), the wireless device can apply a second allowed power based on a second threshold. Similarly, based on the service / priority associated with the second uplink transmission, the wireless device can apply a third threshold or a fourth threshold for the second uplink transmission of the second CG. Different uplink power sharing / coverage can be supported when the quality of the service objectives for each service are different.

[0421] In an example, the wireless device may determine the transmission power of the UL channel based on one or more power control parameters of the UL channel in the cell in which the UL channel is being transmitted. The wireless device may also determine the transmission power based on path loss, spatial filter information (e.g., SRI), etc. The wireless device may determine one or more transmission powers of the corresponding UL channel in OFDM symbol i of time slot n. When determining the power of the UL channel, the wireless device may allocate power based on the order of the UL channel. When determining the power of the UL channel, the wireless device may determine the power as the lowest value of {transmission power of the UL channel, transmission power threshold of the CG, maximum transmission power threshold of the cell, maximum transmission power threshold of the frequency zone}. The frequency zone is determined based on the cell. Based on the order, the wireless device may allocate power from the highest ranked UL channel. In response to applying the second transmission power threshold (e.g., the sum of the first transmission power threshold and the allowed value), the wireless device may select the first ranked (e.g., highest ranked) UL channel. When determining the power of the first-ranked channel, the wireless device may determine the power as the lowest value among {transmission power of the UL channel, the second transmission power threshold of the CG, the maximum transmission power threshold of the cell, and the maximum transmission power threshold of the frequency zone} in response to the first UL channel being associated with the second service or the second priority category. When determining the power of the first-ranked channel, the wireless device may determine the power as the lowest value among {transmission power of the UL channel, the first transmission power threshold of the CG, the maximum transmission power threshold of the cell, and the maximum transmission power threshold of the frequency zone} in response to the first UL channel being associated with the first service or the first priority category. The wireless device may determine one or more powers of other UL channels other than the first-ranked UL channel as the lowest value among {transmission power of the UL channel, the first transmission power threshold of the CG, the maximum transmission power threshold of the cell, and the maximum transmission power threshold of the frequency zone}.

[0422] Fig.17 An embodiment is shown. A wireless device may be configured with a dual connectivity scenario, in which the wireless device is associated with a first cell group (CG1) and a second cell group (CG2). The first base station and / or the second base station may transmit one or more RRC messages indicating a first transmission power threshold for a first CG (e.g., p-Max(CG1)) and a second transmission power threshold for a second CG (e.g., p-Max(CG2)). The first base station and / or the second base station may transmit one or more additional RRC messages indicating an allowed value for a CG (either the first CG or the second CG or applied to both CGs). The allowed value may apply to the first CG, the second CG, or both the first CG and the second CG. For example, Fig.17The wireless device is shown configured with a first allowed value for a first CG and a second allowed value for a second CG. For example, the first allowed value and the second allowed value may be the same. For example, the first base station and / or the second base station may transmit a message including the first allowed value and the second allowed value for each CG, respectively. For example, the first base station and / or the second base station may transmit a message including allowed values ​​applicable to the first allowed value and the second allowed value.

[0423] The allowed value is the additional power that the wireless device can use to transmit the uplink channel (e.g., URLLC service) of the second service. In an example, the wireless device can determine that the uplink channel is used for the service based on the priority value associated with the uplink channel. The first priority value can be used for the first service. The second priority value can be used for the second service. For example, the wireless device can receive a DCI indicating the priority value of the uplink channel, wherein the DCI schedules one or more resources of the uplink channel. For example, the wireless device can receive an RRC message indicating the priority value of the uplink channel, wherein the uplink channel can be transmitted via one or more configured resources (e.g., configured permitted resources, SRS resources, semi-persistent CSI feedback resources, etc.). For example, the wireless device can determine that the uplink channel is for the second service based on the logical channel (LCH) of the data carried by the uplink channel. One or more LCHs can be associated with the first service. One or more second LCHs can be associated with the second service. For example, the wireless device can determine that the uplink channel is for the second service based on the RNTI used in the DCI of the uplink channel scheduled for transmission. For example, C-RNTI can be used for the first service. For example, the second RNTI may be used for the second service. Based on the UE power class or the UE allowed power, the wireless device may allocate power up to p-Max(CG1) to uplink transmissions to CG1. The remaining power (e.g., UE allowed power - allocated power of CG1, PowerClass-p-Max(CG1)) may be considered as reserved / guaranteed / ensured power for CG2. The remaining power will not be used for uplink transmissions to CG1 for at least the first service. Similarly, the wireless device may allocate power up to p-Max(CG2) to uplink transmissions to CG2. The remaining power (e.g., UE allowed power - allocated power of CG2, power class PowerClass–(CG2)) may be considered as reserved / guaranteed / ensured power for CG1 because the remaining power will not be used for uplink transmissions to CG2 for at least the first service. In an example, the first service may indicate an eMBB service. The second service may indicate a URLLC service. At time o, the wireless device allocates less than p-Max(CG1) power to the PUSCH (CG1 PUSCH) of CG1.

[0424] In response to receiving a transmission request for a PUSCH of a second service of CG2 at time p (e.g., CG2 PUSCH (URLLC)), the wireless device may allocate a transmission power greater than p-Max(CG2) to the PUSCH / determine that the transmission power of the PUSCH is greater than that because the PUSCH is for / associated with the second service (e.g., URLLC). In response to allocating power for the CG2 PUSCH at time p, the wireless device may lower the CG1 PUSCH or reduce the power allocated to the CG1 PUSCH. If the wireless device can reduce the power level of an ongoing transmission or the CG1 PUSCH (e.g., a UL channel transmitted at the time of power determination or a UL channel for which the wireless device has determined the power level), the quality of the packet may decrease. Specifically, the situation in which the wireless device can reduce the power on one or more OFDM symbols carrying DM-RS may reduce the quality of the uplink transmission. The wireless device may lower the UL channel (e.g., CG1 PUSCH at time p) in response to one or more OFDM symbols affected by the power adjustment possibly containing DM-RS or the power scaling level being greater than X dB (e.g., X=3). When the wireless device needs to reduce power by more than a certain threshold (e.g., 3dB), the wireless device can reduce transmission instead of reducing power. When the power reduction is greater than the threshold, the wireless device can reduce uplink transmission. In other cases, the wireless device can reduce power and continue uplink transmission.

[0425] When determining the power of the CG2 PUSCH of the second service at time p, the wireless device considers the additional allowed value of the second service. The wireless device can determine the transmission power based on the configured power of the CG2 PUSCH, the allowed power (e.g., PowerClass), and the sum of p-Max(CG2) and the allowed value (e.g., transmission power = minimum {UE allowed power, p-Max(CG2) + allowed value, configured power of CG2PUSCH}). In an example, the wireless device can allocate such a configured power to the CG2 PUSCH, which is less than the sum of the UE allowed power (e.g., PowerClass) and p-Max(CG2) and the allowed value (e.g., configured power <= minimum {UE allowed power, p-Max(CG2) + allowed value}). For example, the wireless device may determine the transmission power of the CG2 PUSCH as the lowest power among {the configured transmission power of the CG2 PUSCH calculated based on one or more power control parameters and path loss, p-Max(CG2)+allowed value, UE allowed power, UE allowed power in the frequency zone, UE allowed power in the cell}. The frequency zone is determined by frequency range 1 or frequency range 2, depending on the frequency of the cell in which the CG2 PUSCH is transmitted.

[0426] For example, the wireless device may allocate a first power to the CG2 PUSCH and a second power to the CG1 PUCCH at time q when the sum of the first power and the second power is less than the UE allowed power. The first power is less than p-Max(CG2) and the second power is less than p-Max(CG1). The wireless device allocates the required / requested / configured power to the UL channel based on one or more configured power control parameters. The wireless device allocates / determines a third power for the CG1 PUSCH used for the second service. The third power is greater than p-Max(CG1) and less than the sum of p-Max(CG1) and the allowed value of CG1. When the PUSCH is used for the second service, the wireless device may allocate / determine a third power that exceeds the first transmission power threshold (p-Max(CG1)).

[0427] In an example, the wireless device may be configured with a first transmission power threshold and a second transmission power threshold of the CG. The wireless device may apply the first transmission power threshold when determining the power level of one or more first uplink channels. The wireless device may apply the second transmission power threshold when determining the power level of one or more second uplink channels. The one or more first uplink channels may include PUCCH, PUSCH and / or SRS transmissions for a first service (e.g., eMBB) or a second service (e.g., URLLC). The one or more second uplink channels may include PUCCH, PUSCH and / or SRS transmissions and / or PRACH transmissions for the second service. For example, PRACH transmissions may be triggered for a beam failure recovery procedure. PRACH transmissions may be triggered by PDCCH commands. For example, the PRACH of a PCell or SPCell may have a higher priority than the PARCH of an SCell. The PRACH of a PCell or SPCell may be regarded as the PRACH of a second service (e.g., the wireless device may allocate power up to a second threshold or UE allowed power). The PRACH of the SCell or SPCell is considered as the first served PRACH (eg, the wireless device may allocate power up to a first threshold or UE allowed power).

[0428] In an example, the wireless device may apply a first transmission power threshold on one or more first uplink channels when one or more of the following conditions are met: the one or more first uplink channels belong to a first service; the one or more first uplink channels do not include a PRACH transmission and belong to the first service; the one or more first uplink channels include only one PRACH transmission, and the configured power on the one PRACH transmission is less than or equal to the first power threshold; the one or more first uplink channels include only one uplink channel of a second service, and the configured power on the one uplink channel is less than or equal to the first power threshold; the one or more first uplink channels include more than one uplink channels of the second service, and the sum of the configured powers of the more than one uplink channels is less than or equal to the first power threshold; and / or the one or more first uplink channels include more than one PRACH transmission, and the sum of the configured powers of the more than one PRACH transmissions is less than or equal to the first power threshold.

[0429] The wireless device may apply a second transmission power threshold on one or more second uplink channels when one or more of the following conditions are met: the one or more first uplink channels belong to the second service; the one or more first uplink channels are PRACHs; the one or more first uplink channels include only one PRACH transmission, and the configured power on the one PRACH transmission is greater than the first power threshold; the one or more first uplink channels include only one uplink channel of the second service, and the configured power on the one uplink channel is greater than the first power threshold; the one or more first uplink channels include more than one uplink channel of the second service, and the sum of the configured powers of the more than one uplink channels is greater than the first power threshold; the one or more first uplink channels include more than one PRACH transmissions, and the sum of the configured powers of the more than one PRACH transmissions is greater than a first power threshold; the one or more first uplink channels include more than one uplink channels of the second service, and the maximum value among the configured powers of the more than one uplink channels is greater than the first power threshold; the one or more first uplink channels include more than one PRACH transmissions, and the maximum value of the configured powers of the more than one PRACH transmissions is greater than the first power threshold; the one or more first uplink channels include more than one uplink channels of the second service, and the configured power of the highest priority uplink channel is greater than the first power threshold; and / or the one or more first uplink channels include more than one PRACH transmissions, and the configured power of the highest priority PRACH is greater than the first power threshold.

[0430] The wireless device can apply the second transmission power threshold based on the duty cycle configuration or the ratio configuration (if configured). For example, if the base station configures a ratio parameter for the second transmission power threshold of CG1, the wireless device can apply the second transmission power threshold as long as the wireless device does not allocate a power greater than the first transmission power threshold of CG1 that is greater than the configured ratio parameter. For example, the ratio parameter is 50%. The wireless device can record the first time that a power higher than the first transmission power threshold is allocated to CG1. The wireless device can record the second time that a power lower than or equal to the first transmission power threshold is allocated to CG1. As long as the ratio of the first time / (first time + second time) is greater than the configured ratio, the wireless device can not use the second transmission power threshold.

[0431] In an example, the first base station and / or the second base station may configure a duty cycle, where the wireless device may use a transmission power threshold that is higher than the lower transmission power threshold of the CG. For example, the duty cycle may be used for a second priority class UL transmission (e.g., allowing the wireless device to apply a higher transmission power threshold only when all one or more UL channels are one or more URLLC UL channels). For example, when the duty cycle is met, the duty cycle may be used for the CG regardless of the priority class of the UL channel. For example, the duty cycle may be used when the wireless device may have at least one second priority / high priority UL service for the CG. For example, the duty cycle may be used when the wireless device may have at least one second / high priority UL transmission, where the transmission power of the UL transmission may exceed the lower transmission power threshold of the CG. Regardless of the power class, the duty cycle may be configured to share power in different modes at different times. In an example, the duty cycle may also be configured with an allowed value for the CG. If configured, the wireless device may be allowed to exceed the maximum / allowed power of the CG (e.g., p-Max(CG)+allowed value) for the second service within the duty cycle. For example, when the duty cycle is 50%, the wireless device may exceed or utilize up to 50% of the configured allowed value for uplink transmissions / uplink timeslots / transmission times / durations.

[0432] Fig.18An example of an embodiment of an allowed value configured to a first CG is shown. For example, the first CG may operate NR. The second CG may operate LTE. For example, the first CG may operate a slow processing RAT. The second CG may operate a fast processing RAT. The first base station or the second base station may configure a first transmission power threshold (PCmax(CG1)) of CG1. The first base station and / or the second base station may configure a second transmission power threshold (PCmaxL(CG2)) of CG2 and a third transmission power threshold (PCmaxH(CG2)) of CG2. In response to receiving two transmission power thresholds, the wireless device may apply different transmission power thresholds for different services. In response to receiving the transmission power threshold, the wireless device may apply the transmission power threshold for all services / channels of the CG. In an example, in response to receiving only one transmission power threshold of the CG, the wireless device may assume that the second transmission power threshold is the UE allowed power.

[0433] exist Fig.18 , the wireless device applies a single transmission power threshold to all uplink channels of CG1. At time o, the wireless device allocates power up to the configured power of CG1 PUSCH to CG1 PUSCH. At time p, when the PUSCH is for a second service, the wireless device allocates power up to a third transmission power threshold of CG2. The wireless device may reduce or lower CG1 PUSCH in response to reducing the power on CG1 PUSCH. At time p, when the sum of the configured powers does not exceed the UE allowed power, the wireless device allocates the configured powers of CG2 PUSCH and CG1 PUSCH. At time r, the wireless device may allocate PCmax(CG1) that is lower than the configured power of CG1 PUSCH to CG1 PUSCH. Since the wireless device is configured with a single transmission power threshold for CG1, the wireless device may not allocate power greater than the configured threshold of CG1 regardless of the service type. The wireless device may reduce the power allocated to CG2 PUSCH at time p up to the reserved power of CG2. The wireless device may allocate power lower than the configured power of the CG1 PUSCH at time r.

[0434] In an example, in response to the current remaining power possibly not satisfying the configured power of the second uplink channel of another CG, the wireless device may acquire some or all of the power allocated to the first channel being transmitted by the CG. Fig.18, the wireless device obtains power from CG1 PUSCH (the first PUSCH of CG1) for CG2 PUSCH at time p. When the second channel has a higher priority than the first channel, the wireless device may obtain power of the first channel being transmitted for the second channel. When the second channel has an equal or lower priority than the first channel, the wireless device may not obtain power of the first channel being transmitted for the second channel.

[0435] Fig.19 The case of more than one uplink channel between CGs of the second service conflict is shown. The first base station or the second base station can configure a first transmission power threshold (PCmaxL(CG1)) and a second transmission power threshold (CGMaxH(CG1)) for CG1. The first base station or the second base station can configure a third transmission power threshold (CGmaxL(CG2)) and a fourth transmission power threshold (CGmaxH(CG2)) for CG2. When the configured power is less than the first power threshold, the wireless device can allocate power to CG1 PUSCH based on the configured power on CG1 PUSCH at time o. At time p, the wireless device may need to allocate power to CG2 PUSCH and reduce the power on CG1 PUSCH. The wireless device allocates the configured power of CG2 PUSCH that is lower than the fourth transmission power threshold of CG2. In response to another PUSCH (CG1 PUSCH for URLLC) within time q, the wireless device may not allocate the configured power of CG1 PUSCH to URLLC when it needs to reduce the power allocated to CG2 PUSCH. When the CG2 PUSCH occurs earlier than the CG1 PUSCH, the wireless device may prioritize the earlier transmission when the two channels have the same priority (eg, both channels are used for the second service).

[0436] In an example, the wireless device may have a first processing capability for a first channel. The wireless device may have a second processing capability for a second channel. The first processing capability may be faster than the second processing capability. For example, the wireless device may need to receive an UL grant that schedules the first channel at time n. For example, the wireless device may need to receive an UL grant that schedules the second channel at time p (where p is earlier than n). When the UL grant for the second channel is received at time p, the wireless device may allocate the configured power to the second channel that appears at the Kth OFDM symbol in time slot m. When the first channel and the second channel may have the same priority or the first channel has a lower priority than the second channel, the wireless device may not reduce the power allocated to the second channel when the UL grant for the first channel is received at time n.

[0437] Fig. 20An example is shown. A first base station (gNB1) transmits an UL grant at time p, which is the latest time to schedule a PUSCH scheduled at time r with a processing time constraint. A second base station (gNB2) transmits an UL grant at time n, which is the latest time to schedule a PUSCH scheduled at time o with a processing time constraint. Upon receiving the UL grant at time p, the wireless device may allocate power up to the configured power of the CG1 PUSCH for the CG1 PUSCH. In the case where power has been allocated to the CG1 PUSCH and the two PUSCHs have the same priority, upon receiving the UL grant at time n, the wireless device may allocate only the remaining power to the CG2 PUSCH. In an example, when the second channel is used for the primary CG, the wireless device may obtain some or all of the power allocated to the first channel for use with the second channel with the same priority. Reducing power or reducing part of the transmission during transmission may degrade the performance of the transmission. To ensure QoS of the UL channel, the wireless device may not reallocate power already allocated to the uplink channel when the priority value of the uplink channel is high or the uplink channel is used for a second service (e.g., URLLC). When the base station can configure the wireless device with the option of not changing power during transmission (e.g., via RRC signaling), the wireless device may not reallocate power already allocated to the uplink channel. When the wireless device can determine based on the embodiment, the wireless device may reallocate power already allocated to the uplink channel.

[0438] In an example, the wireless device may have multiple uplink channels for the CG. For example, the priority of only one uplink channel from the multiple uplink channels is a high priority or the uplink channel is associated with a second service type (e.g., URLLC). The wireless device may determine a first transmission power threshold or a second transmission power threshold for applying the CG based on the configured transmission power of the uplink channel. For example, if the configured transmission power of the uplink channel is less than or equal to the first power threshold, the wireless device may apply the first transmission power threshold when determining the power of the multiple uplink channels of the CG. For example, if the configured transmission power of the uplink channel is greater than the first power threshold, the wireless device may apply the second transmission power threshold when determining the power of the multiple uplink channels of the CG.

[0439] When the wireless device applies the second transmission power threshold to this situation, the wireless device may allocate "zero" power to the multiple uplink channels of the CG in addition to the uplink channels. For example, when the wireless device may have more than one uplink channel with a high priority among the multiple uplink channels of the CG, the wireless device may select a single uplink channel that may have the highest priority. The wireless device may select the earliest UL transmission among the more than one uplink channels with a high priority. The wireless device may select a single uplink transmission that can be allocated a power greater than the first power threshold. For example, if the configured transmission power of the selected single uplink transmission is greater than the first power threshold, the wireless device may apply the second transmission power threshold when determining the power of the multiple uplink channels of the CG. When the wireless device applies the second transmission power threshold to this situation, the wireless device may allocate "zero" power to the multiple uplink channels of the CG in addition to the selected single uplink transmission. Otherwise, the wireless device may apply the first transmission power threshold when determining the power of the multiple uplink channels of the CG.

[0440] Fig.21An example is shown. A first base station (e.g., gNB1) may schedule a UL grant for CG1 scheduled at time o. The configured power of the first PUSCH of CG1 is less than the first transmission power threshold of CG1. The wireless device allocates the configured power to the first PUSCH of CG1. A second base station (e.g., gNB2) may schedule a UL grant for CG2 scheduled at time p. The configured power of the CG2 PUSCH is less than the first transmission power threshold of CG2. The wireless device allocates the configured power to the CG2 PUSCH at time p. When the CG2 PUSCH is associated with a second service at time q, when the wireless device allocates power to the CG2 PUSCH scheduled at time q, the wireless device determines whether to use the first transmission power threshold or the second transmission power threshold to schedule the CG2 PUSCH. In response to a lower configured power of the CG2 PUSCH at time q compared to a first transmission power threshold of CG2 (e.g., PCmaxL(CG2)), the wireless device reduces the power of the earlier PUSCH (e.g., CG2 PUSCH at time p) and allocates more power to the second PUSCH of CG2. When the configured power of the CG1 PUSCH scheduled at time r is greater than the first threshold of CG1 (e.g., PCmaxL(CG1), when the wireless device allocates power to the PUSCH of CG1 at time r, the wireless device uses the second transmission power threshold of CG1 (e.g., PCmaxH(CG1)). The wireless device may reduce the power of the CG2 PUSCH from the CG2 scheduled at time p, or lower the CG2 PUSCH scheduled at time p, to reallocate power to the CG1 PUSCH for a second service (e.g., CG1 PUSCH (URLLC)).

[0441] In an example, the wireless device may first perform a power determination of one or more first uplink channels of the CG based on a first transmission power threshold of the CG. When the wireless device may require the sum of the configured powers of the one or more first uplink channels to be greater than the first transmission power threshold of the CG, the wireless device may apply a second transmission power threshold of the CG. The wireless device may determine whether there is at least one uplink channel with a high priority or associated with a second channel, where the configured power of the channel is greater than the first power threshold. In the case where at least one high priority channel of the wireless device requires a power higher than the first power threshold, the wireless device may apply the second transmission power threshold when determining the power of the one or more first uplink channels. Otherwise, the wireless device may apply the first transmission power threshold when determining the power of the one or more first uplink channels. When the wireless device determines to use the second transmission power threshold of the CG, the wireless device may configure the transmission power threshold of the CG based on the lower value between the configured power of the uplink channel with a high priority or associated with the second service and the second power threshold. When the wireless device may have more than one uplink channel for a CG with a high priority or associated with a second service, the wireless device may select a single uplink channel based on a priority rule. If the configured power of a single uplink channel is above the first threshold of the CG, the wireless device may apply a second transmission power threshold when determining the power level of the single uplink channel. Otherwise, the wireless device may use the first power threshold.

[0442] In an example, the wireless device may apply a first transmission power threshold of the CG in response to all uplink channels at a given time being associated only with the first service or having a low priority. The wireless device may apply a second transmission power threshold of the CG in response to any uplink channel associated with the second service or having a high priority at a given time. In this case, the wireless device may have a first uplink channel with a high priority in the first CG and a second uplink channel with a high priority in the second CG, and the wireless device may prioritize the first uplink channel or the uplink channel of the first CG, and / or may prioritize earlier uplink transmissions that occur within a certain time, and / or may prioritize earlier scheduled uplink transmissions, and / or may prioritize dynamic uplinks over configured permitted uplink transmissions.

[0443] In an example, the wireless device may apply the second transmission power threshold of the CG in response to the sum of the configured powers of one or more uplink channels associated with the second priority or having a high priority for the CG being greater than the first transmission power threshold of the CG. The wireless device may apply the first transmission power threshold in other cases. In an example, the wireless device may apply the second transmission power threshold of the CG in response to the sum of the configured powers of one or more uplink channels of the CG being greater than the first threshold of the CG, and there being at least one UL channel associated with the second service or having a high priority among the one or more uplink channels. The wireless device may apply the first transmission power threshold of the CG in other cases.

[0444] Based on the determined thresholds of the CG (e.g., a first power threshold, a second power threshold, a configured power of the UL channel, etc.), the wireless device may perform power determination within the CG. For example, the wireless device may have a first uplink channel, a second uplink channel, a third uplink channel, and a fourth uplink channel. The wireless device may determine the order of the uplink channels based on: transmission timing (e.g., a UL channel having an OFDM symbol that starts earlier in a time slot may have a higher priority than another UL channel having an OFDM symbol that starts later in the time slot), associated services (e.g., a UL channel associated with a second service may have a higher priority than another UL channel associated with a first service), data type (e.g., PRACH may have a higher priority than SR / PUCCH with HARQ-ACK feedback, SR / PUCCH with HARQ-ACK feedback may have a higher priority than PUSCH with HARQ-ACK feedback, or PUSCH with HARQ-ACK feedback may have a higher priority than PUSCH with HARQ-ACK feedback). PUSCH with ARQ-ACK feedback may have a higher priority than SR / PUCCH with HARQ-ACK feedback, PUCCH with HARQ-ACK feedback / PUCCH with HARQ-ACK feedback may have a higher priority than PUSCH, aperiodic SRS / CSI feedback with PUSCH / PUCCH may have a higher priority than data of PUSCH only), the priority of the UL channel (e.g., a priority value is associated with each UL channel), and / or the cell index to which the wireless device may transmit the uplink channel (e.g., a UL channel to a lower index cell may have a higher priority than another UL to a higher index cell).

[0445] Fig. 22An example of semi-static power sharing between two CGs is shown. In the example, the first base station and / or the second base station can share power based on a semi-static power split (e.g., PCmaxL(CG1)+PCmaxL(CG2)<=UE allowed power). The wireless device can allocate power up to a first threshold (e.g., PCmaxL(CG1)) to the first CG, and can allocate power up to a second threshold (e.g., PCmaxL(CG2)) to the second CG for non-URLLC uplink transmission. The first base station and / or the second base station can configure an additional allowed value or another threshold that can be used for URLLC UL services (e.g., PCmaxH(CG1) for the first CG, PCmaxH(CG2) for the second CG). The wireless device can apply a higher transmission power threshold to schedule URLLC UL in the first CG.

[0446] For example, when the transmission power of each channel is lower than the lower power of the CG, the wireless device may allocate transmission power on the CG2 PUSCH and the transmission power of the CG1 PUSCH at time o. In response to receiving a URLLC PUSCH that requires a power higher than the lower threshold of the second CG at time p, the wireless device may allocate transmission power on the CG2 PUSCH and reduce the power on the CG1 PUSCH. In time q, the wireless device may allocate a transmission power higher than the lower threshold of CG1 on the CG1 PUSCH (e.g., PCmaxL(CG1)).

[0447] The base station may transmit a PDCCH command via DCI to trigger a PRACH transmission. The base station may allocate a dedicated sequence / preamble for PRACH transmission. The base station may use a first PRACH format for a first service and a second PRACH format for a second service. For example, the first PRACH format may be a long PRACH format to support large coverage. For example, the second PRACH format may be a short PRACH format to support low latency PRACH transmission. The base station may indicate the PRACH format to be used in the PRACH transmission in the PDCCH command. For example, the base station may use the first RNTI in the PDCCH command to request a PRACH transmission based on the first PRACH format. The base station may use the second RNTI in the PDCCH command to request a PRACH transmission based on the second PRACH format. For example, the base station may have a DCI field indicating the PRACH format in the PRACH transmission. For example, the base station may use the first search space to schedule the PDCCH command based on the first PRACH format. The base station may use the second search space to schedule the PDCCH command based on the second PRACH format.

[0448] In response to receiving the PRACH format, the wireless device determines the PRACH format as indicated. For example, the first PRACH format may have a lower priority than the second PRACH format. When the wireless device may conflict between the first PRACH and the second PRACH based on the second PRACH format, the wireless device may reduce the first PRACH based on the first PRACH format. The wireless device may allocate power up to a second transmission power threshold on the second PRACH of CG1. The wireless device may allocate power up to a first transmission power threshold on the first PRACH of CG1. The first PRACH format may be the same as the second PRACH format. The PRACH for beam failure recovery may be regarded as a PRACH for a second service or a PRACH based on a second PRACH format. The PRACH for beam failure recovery may have a higher priority than another PRACH. In terms of the priority of one or more PRACH transmissions, an order may be determined.

[0449] For example, PRACH due to SR>PRACH due to beam failure>PRACH based on PDCCH order>PRACH due to other reasons can be used as the order. For example, PRACH triggered by SR failure may have a higher priority. In response to a first PRACH caused by a first SR failure and a second PRACH caused by a second SR failure conflict, the priority between the first PRACH and the second PRCH can be determined based on the priority between the first SR and the second SR. The priority of the first SR and the second SR can be determined based on the LCH mapping to the first SR and the second SR. The highest LCH priority mapped to the SR can determine the priority value of the SR. The SR with a higher priority value is regarded as a higher priority SR.

[0450] In an example, a PRACH for a two-step RACH procedure may be considered to have a higher priority than a PRACH for a four-step RACH procedure. For example, the PRACH may be sorted first based on the cause of the RACH being triggered, and then the RACH may be prioritized with a two-step RACH and a contention-based RACH for the same reason (e.g., two-step PRACH with contention>two-step PRACH without contention>four-step PRACH with contention>four-step PRACH without contention, or two-step PRACH with contention>four-step PRACH with contention>two-step PRACH without contention>four-step PRACH without contention). For example, the PRACH may be sorted first based on two or four steps, secondly based on contention and no contention, and based on the cause of the RACH being triggered. For example, the PRACH may be sorted first based on contention and no contention, secondly based on two or four steps, and then based on the cause of the RACH being triggered. For example, the PRACH may be sorted first based on the cause of the RACH being triggered, secondly based on contention and no contention, and then based on two or four steps.

[0451] In an example, the wireless device may determine the priority / priority class or service associated with the SR transmission based on one or more of the following: Logical channel (LCH) mapping to the SR configuration: If more than one LCH is mapped to the SR, the LCH with the highest priority among the more than one LCH (or the LCH with the lowest priority among the more than one LCH) may be used to determine the priority or service of the SR transmission; Periodicity of the SR configuration: For example, if the periodicity is less than a time slot based on the parameter set of the active UL BWP of the SR configuration or SR transmission, the SR configuration / transmission is considered high priority or associated with the second service. Otherwise, the SR configuration / transmission is considered low priority or associated with the first service; Priority is explicitly configured in the SR configuration: The base station may configure the priority level / value used in the SR configuration. The wireless device may follow the configured / indicated priority level / value when determining the priority value of the SR.

[0452] In an instance, the wireless device may determine a priority or priority category or service associated with a PUCCH transmission based on uplink control information transmitted via the PUCCH. For example, a PUCCH transmission may carry one or more beam failure indications, one or more SR indications, one or more HARQ-ACK feedbacks, one or more periodic CSI feedbacks, one or more non-periodic CSI feedbacks, and the like. Priority may be determined depending on the content transmitted via the PUCCH. When the PUCCH carries more than one content, the content with the highest priority or the lowest priority may be used to determine the priority. When determining the priority / priority category of the one content, in an instance, the wireless device may use an explicitly configured priority / priority category for the resources indicated for the content. For example, when transmitting one or more HARQ-ACK feedbacks, the PUCCH resources are dynamically or semi-statically indicated.

[0453] The base station may configure the priority of the PUCCH resource in another RRC message. The wireless device may use the configured priority of the PUCCH resource for HARQ-ACK feedback. When the wireless device can use different resources for UCI multiplexing, the priority of each content may be determined based on the original PUCCH resource configuration before multiplexing. For CSI feedback, the base station may configure the priority of the CSI-RS configuration or the CSI report configuration. The wireless device may determine the priority of the content based on the configuration. In an example, the wireless device may determine the priority of the HARQ-ACK feedback based on one or more corresponding PDSCHs. For example, if the one or more corresponding PDSCHs are associated with a first service or a first RNTI, the HARQ-ACK feedback is considered to be a first / low priority. If the one or more corresponding PDSCHs are associated with a second service or a second RNTI, the HARQ-ACK feedback is considered to be a second / high priority. For CSI feedback, the wireless device may assume that periodic CSI feedback is a low priority and may assume that non-periodic CSI feedback is a high priority unless the base station is configured differently.

[0454] In an example, the wireless device may associate a priority with the SRS. The base station may configure a priority value for the SRS resource / SRS resource set configuration. When a priority value is not configured in the SRS configuration, the wireless device may assume that the periodic SRS is associated with a low / first priority and the aperiodic SRS is associated with a high / second priority.

[0455] In an instance, the wireless device may determine the priority of the PUSCH based on the content of the PUSCH and the RNTI / priority associated with the configured granted resources and / or scheduling DCI. For example, the wireless device may multiplex first priority UCI content to a PUSCH with second priority data (or vice versa (e.g., multiplexing the second priority PUSCH to the first priority UCI content)). The wireless device may piggyback HARQ-ACK feedback associated with one or more URLLC PDSCHs on the eMBB PUSCH. When the wireless device may multiplex the first priority UCI to the second priority PUSCH, the wireless device may determine the priority of the PUSCH based on the higher priority value between the first priority and the second priority. In an instance, the wireless device is not allowed to piggyback the first priority UCI content to the second priority PUSCH, and vice versa. When the wireless device may not multiplex different priorities in the PUSCH, the priority of the PUSCH may be determined based on the priority of the data transmitted via the PUSCH. In an example, when a second priority PUCCH with UCI may conflict with a first priority PUSCH instead of piggybacking on the PUSCH, the wireless device may drop the lower priority uplink channel when the wireless device cannot transmit both. In an example, the wireless device is not allowed to piggyback the first priority UCI content to the second priority PUSCH, but is allowed to piggyback the second priority UCI content to the first priority PUSCH. In an example, the first priority is assumed to be a lower priority than the second priority. When the wireless device can allocate one or more configured powers of the first priority PUSCH, assuming that the priority of the PUSCH is the first priority, the second priority UCI may be allowed to piggyback to the first priority PUSCH data.

[0456] In an example, based on the priority of the UL channel, the order of different UL channels when allocating power within a cell group may be: PRACH with high priority > SR / PUCCH with HARQ-ACK feedback with high priority > PUSCH with HARQ-ACK feedback with high priority > PUSCH with non-periodic CSI feedback with high priority > non-periodic SRS with high priority > PUSCH with periodic CSI feedback or PUSCH with data only with high priority > periodic SRS with high priority > PRACH with low priority > SR / PUCCH with HARQ-ACK feedback with low priority > PUSCH with HARQ-ACK feedback with low priority > PUSCH with non-periodic CSI feedback or PUSCH with data only with low priority > non-periodic SRS with low priority > PUSCH with periodic CSI feedback with low priority > periodic SRS with low priority > PRACH for secondary cells.

[0457] The wireless device determines that a first UL channel having a high priority has a higher priority than a second UL channel having a low priority, regardless of the content of the first UL channel and the second UL channel. In an example, the order of the UL channels can be determined based on the content of the UL channels first. For UL channels with the same content, the order is determined using the priority value. In an example, SRS can be treated differently (e.g., SRS transmission is deprioritized relative to other UL channels). For example, the order can be: PRACH with high priority>SR / PUCCH with HARQ-ACK feedback with high priority>PUSCH with HARQ-ACK feedback with high priority>PUSCH with non-periodic CSI feedback with high priority>PUSCH with periodic CSI feedback or PUSCH with data only with high priority>PRACH with low priority>SR / PUCCH with HARQ-ACK feedback with low priority>PUSCH with HARQ-ACK feedback with low priority>PUSCH with non-periodic CSI feedback with low priority>PUSCH with periodic CSI feedback or PUSCH with data only with low priority>non-periodic SRS with high priority>non-periodic SRS with low priority>periodic SRS with high priority>periodic SRS with low priority.

[0458] The PRACH of a PCell or SPCell may be considered as the PRACH of a second service (e.g., the wireless device may allocate power up to a second threshold or the UE may allow power). The PRACH of an SCell or SPCell may be considered as the PRACH of a first service (e.g., the wireless device may allocate power up to a first threshold or the UE may allow power).

[0459] In an example, the wireless device may prioritize as follows: PRACH transmission on PCell or SPCell>PUCCH transmission with HARQ-ACK and / or SR or PUSCH transmission with HARQ-ACK information>PUCCH transmission with CSI or PUSCH transmission with CSI>PUSCH transmission without UCI>SRS transmission with aperiodic SRS>SRS transmission with semi-persistent and / or periodic and / or PRACH transmission of SCell. In an example, the rule may be extended for one or more priorities so that the wireless device may prioritize one or more UL channels with high priority over one or more UL channels with low priority. For example, the order may be: PRACH transmission with high priority on PCell or SPCell>PUCCH transmission with HARQ-ACK with high priority and / or SR or PUSCH transmission with HARQ-ACK information>PUCCH transmission with CSI with high priority or PUSCH transmission with CSI>PUSCH transmission without UCI with high priority>SRS transmission with aperiodic SRS with high priority>SRS transmission with semi-persistent and / or periodic SRS transmission with high priority and / or PR with high priority on SCell ACH transmission > PRACH transmission with low priority on PCell or SPCell > PUCCH transmission with HARQ-ACK with low priority and / or SR or PUSCH transmission with HARQ-ACK information > PUCCH transmission with CSI with low priority or PUSCH with CSI > PUSCH transmission without UCI with high priority > SRS transmission with aperiodic SRS with low priority > SRS transmission with semi-persistent and / or periodic SRS with low priority and / or PRACH transmission with low priority of SCell.

[0460] In an example, the wireless device may prioritize multiple uplink channels based on the following order: PRACH transmission on PCell or SPCell > PUCCH transmission with HARQ-ACK and / or SR or PUSCH transmission with HARQ-ACK information with high priority > PUCCH transmission with CSI or PUSCH transmission with CSI with high priority > PUSCH transmission without UCI with high priority > PUCCH transmission with HARQ-ACK and / or SR or PUSCH transmission with HARQ-ACK information with low priority > PUCCH transmission with CSI or PUSCH transmission with CSI with low priority > PUSCH transmission without UCI (with high priority) > SRS transmission with non-periodic SRS (with low priority) > SRS transmission with semi-persistent and / or periodic SRS transmission (with low priority) and / or PRACH transmission of SCell.

[0461] For example, the order may be: PRACH with high priority > PRACH with high priority > SR / PUCCH with HARQ-ACK feedback with high priority > SR / PUCCH with HARQ-ACK feedback with low priority > PUSCH with HARQ-ACK feedback with high priority > PUSCH with HARQ-ACK feedback with low priority > PUSCH with non-periodic CSI feedback with high priority > PUSCH with non-periodic CSI feedback with low priority > non-periodic SRS with high priority > non-periodic SRS with low priority > PUSCH with periodic CSI or PUSCH with data only with high priority > PUSCH with periodic CSI feedback or PUSCH with data only with low priority > periodic SRS with high priority > periodic SRS with low priority.

[0462] In an example, an order among multiple UL channels in a carrier is first determined based on the priority values ​​of the multiple UL channels (e.g., prioritizing high priority UL channels), and then determined based on the content of the multiple channels. An order among a second plurality of channels among carriers in a carrier group is first determined based on the content of the second plurality of channels, and then determined based on the priority values ​​of the second plurality of channels of the same content channels. In an example, an order based first on priority value and second on content is used for multiple UL channels in a carrier. Then, an order based first on content and second on priority value is used for multiple UL channels among multiple carriers in a cell group.

[0463] When determining the order of power determination in the cell group, the wireless device may prioritize the uplink channel when the uplink channel has been transmitted or power on the uplink channel has been allocated. The wireless device may place the uplink channel first among uplink channels with the same priority. For example, if the wireless device has allocated power on the first PUSCH for eMBB, the wireless device may prioritize the first PUSCH of eMBB over the PRACH with a lower priority.

[0464] In an example, the wireless device may determine a first UL channel of a first CG and a second UL channel of a second CG. Based on the sorting, the first UL channel may be the first UL channel of the first CG. Based on the sorting, the second UL channel may be the first UL channel of the second CG. If the configured power of the first UL is greater than the first threshold of the first CG and the priority value of the first UL channel is high priority, the wireless device may apply the second transmission power threshold of the first CG to the first UL channel. If the configured power of the second UL is greater than the first threshold of the second CG and the priority value of the second UL channel is high priority, the wireless device may apply the second transmission power threshold of the second CG to the second UL channel.

[0465] The determined threshold is applied to the power determined within the CG. Based on the first-ranked UL channel of the first CG and the second-ranked UL channel of the second CG, the wireless device can determine the ranking of the sum of the first-ranked UL channel and the second-ranked UL channel based on the ranking within the CG. The ranking rules can follow the same rules within the CG. When a first channel from a first CG and a second channel from a second CG may have the same priority / order based on the rules, the wireless device may assume that the first CG channel has a higher priority or is placed in an earlier order. Alternatively, an earlier transmission (e.g., starting an OFDM symbol faster) can be determined for an earlier order. In an example, when the wireless device can support dynamic power sharing between CGs, the ranking between CGs can be applied.

[0466] In an example, the wireless device may not support dynamic power sharing between CGs. The base station may configure a first transmission power threshold and a second transmission power threshold for a first CG. The wireless device may determine whether to use the first transmission power threshold or the second transmission power threshold as specified in the specification. When the wireless device determines to use the second transmission power threshold for the first CG, the wireless device may reduce one or more uplink channels of the second CG. In an example, the wireless device may not support dynamic power sharing between CGs.

[0467] The first base station or the second base station may configure the first transmission power threshold and the second transmission power threshold of the first CG. The first base station or the second base station may configure the first group of time slots in which the first transmission power threshold is applied. The base station may configure the second group of time slots in which the second transmission power threshold is applied. The first base station or the second base station may configure the first transmission power threshold and the second transmission power threshold of the second CG. The first base station or the second base station may configure the first group of time slots in which the first transmission power threshold is applied to the second CG. The base station may configure the second group of time slots in which the second transmission power threshold is applied to the second CG. The base station configures the transmission power threshold and the time slot group so that the sum of the threshold of the CG in the time slot and the other threshold of the second CG does not exceed the UE allowed power. The wireless device may apply different thresholds based on the first group of time slots and the second group of time slots of the CG. The wireless device may apply different thresholds based on the first group of time slots and the second group of time slots of the second CG.

[0468] In an example, more than one LCH may be mapped to a PUSCH or PDSCH, and the wireless device may determine the priority or priority class of the PUSCH or PDSCH based on the highest priority of the mapped LCH, based on the highest priority of the actual transmitted payload, based on the lowest priority of the mapped LCH, based on the lowest priority of the actual transmitted payload, based on the RNTI of the scheduling DCI that schedules the PUSCH or PDSCH, or based on the RRC configuration of the configured grant for the PUSCH or the SPS configuration for the PDSCH. For example, the MAC layer may indicate the priority class of the uplink channel based on the data transmitted via the uplink channel. For example, the priority class of the uplink channel may be determined based on the RNTI of the DCI that schedules the uplink channel. For example, the priority class of the PUCCH carrying the HARQ-ACK feedback for the PDSCH may be determined based on the RNTI of the DCI that schedules the PDSCH. For example, based on a scheduling DCI for the uplink channel or one or more DCI fields of a DCI indicating an uplink channel (e.g., a DCI scheduling a PDSCH indicating a PUCCH transmission for HARQ feedback), the wireless device may determine a priority class for the uplink channel. For example, based on one or more RRC configurations, the wireless device may determine a priority class for the uplink channel (e.g., a priority class configured for a configured grant configuration).

[0469] In an example, a base station may configure an RNTI for retransmitting a configured licensed resource or SPS. The base station may configure a first RNTI for a first priority. The base station may configure a second RNTI for a second priority. Based on the configured RNTI, the wireless device may determine the priority of the configured authorized resource or SPS. In an example, the base station may configure the priority on the configured license or SPS. The wireless device may apply the configured priority in utilizing the configured license or SPS. In an example, the wireless device may determine the priority based on the periodicity and / or duration and / or repetition factor of the configured license configuration or SPS configuration. For example, the wireless device may determine a high priority for a configured license or SPS, which has a periodicity shorter than K time slots (e.g., K=1), or has less than M OFDM symbols (e.g., M=4), or has more than P repetitions (e.g., P=2).

[0470] The configured priority or priority class (e.g., based on RNTI or based on an explicit priority value) may be used to determine mapping of one or more LCHs to a configured grant or SPS. The configured priority may be used to determine multiplexing of one or more UCI (e.g., HARQ-ACK, SR, CSI) in a PUSCH transmission based on the configured grant.

[0471] In an example, when the configured power for PRACH is not allocated due to power scaling (where the configured power for PRACH is equal to or less than the UE allowed power), the wireless device may reduce PRACH transmission. In an example, when the configured power for SRS is not allocated due to power scaling (where the configured power for SRS is equal to or less than the UE allowed power), the wireless device may reduce SRS. In an example, if the configured power is not allocated due to power scaling, the wireless device may reduce power or reduce the UL channel.

[0472] In an example, the wireless device may multiplex a first priority of UCI (e.g., HARQ-ACK feedback) to a second priority PUSCH. For example, the wireless device may transmit a first priority of UCI piggybacked on a first priority PUSCH. The wireless device may need to reduce power or reduce the first priority PUSCH. In order to minimize the reduction or performance degradation of UCI, the wireless device may multiplex the first priority UCI in the second priority PUSCH. The wireless device may allocate more power to transmit the first priority UCI using the second priority PUSCH. In an example, the wireless device may multiplex a first priority of UCI (e.g., HARQ-ACK feedback) to a second priority PUCCH. For example, the wireless device may transmit a first priority of UCI piggybacked on a first priority PUCCH. The wireless device may need to reduce power or reduce the first priority PUCCH. In order to minimize the reduction or performance degradation of UCI, the wireless device may multiplex the first priority UCI in the second priority PUCCH. The wireless device may allocate more power to transmit the first priority UCI using the second priority PUCCH. In an example, the wireless device may transmit PUCCH for first priority UCI in response to the reduction of the first priority PUSCH, where the first priority UCI will be piggybacked due to power scaling. The wireless device may fall back to PUCCH transmission (e.g., not piggybacking on PUSCH if power on PUSCH is insufficient). When the wireless device cannot allocate the configured power for PUSCH due to power scaling, the wireless device may not perform piggybacking on PUSCH.

[0473] In an example, the first base station or the second base station may configure a first transmission power threshold for the configured resources, or a second transmission power threshold for the configured resources. Similarly, the first base station or the second base station may configure a first transmission power threshold or a second transmission power threshold for PUSCH scheduled by UL grant based on RNTI (e.g., C-RNTI uses the first transmission power threshold and the new URLLC-RNTI uses the second power threshold). The wireless device may be configured with a transmission power threshold assumed in a resource pool for sidelink operation.

[0474] Fig.23An example of an RRC message including an allowed value parameter (e.g., additional-Allowance) is shown. The wireless device may receive an RRC message for a CG. In an example, the first base station or the second base station may configure p-NR-FR1 as a first transmission power threshold for the CG. The first base station or the second base station may configure an additional allowed value, wherein the sum of p-NR-FR1 and the additional allowed value may determine a second power threshold. The wireless device may apply a first transmission power threshold to one or more uplink channels of a first service. The wireless device may apply a second transmission power threshold to one or more uplink channels associated with the first service and / or the second service based on additional determination conditions specified in the specification.

[0475] In an example, the wireless device may prioritize as follows: PRACH transmission on PCell or SPCell>PUCCH transmission with HARQ-ACK and / or SR or PUSCH transmission with HARQ-ACK information>PUCCH transmission with CSI or PUSCH transmission with CSI>PUSCH transmission without UCI>SRS transmission with aperiodic SRS>SRS transmission with semi-persistent and / or periodic and / or PRACH transmission of SCell. In an example, the rule may be extended for one or more priorities so that the wireless device may prioritize one or more UL channels with high priority over one or more UL channels with low priority. For example, the order may be: PRACH transmission with high priority on PCell or SPCell>PUCCH transmission with HARQ-ACK with high priority and / or SR or PUSCH transmission with HARQ-ACK information>PUCCH transmission with CSI with high priority or PUSCH transmission with CSI>PUSCH transmission without UCI with high priority>SRS transmission with aperiodic SRS with high priority>SRS transmission with semi-persistent and / or periodic SRS transmission with high priority and / or PR with high priority on SCell ACH transmission > PRACH transmission with low priority on PCell or SPCell > PUCCH transmission with HARQ-ACK with low priority and / or SR or PUSCH transmission with HARQ-ACK information > PUCCH transmission with CSI with low priority or PUSCH with CSI > PUSCH transmission without UCI with high priority > SRS transmission with aperiodic SRS with low priority > SRS transmission with semi-persistent and / or periodic SRS with low priority and / or PRACH transmission with low priority of SCell.

[0476] In an example, the wireless device may prioritize multiple uplink channels based on the following order: PRACH transmission on PCell or SPCell > PUCCH transmission with HARQ-ACK and / or SR or PUSCH transmission with HARQ-ACK information with high priority > PUCCH transmission with CSI or PUSCH transmission with CSI with high priority > PUSCH transmission without UCI with high priority > PUCCH transmission with HARQ-ACK and / or SR or PUSCH transmission with HARQ-ACK information with low priority > PUCCH transmission with CSI or PUSCH transmission with CSI with low priority > PUSCH transmission without UCI (with high priority) > SRS transmission with non-periodic SRS (with low priority) > SRS transmission with semi-persistent and / or periodic SRS transmission (with low priority) and / or PRACH transmission of SCell.

[0477] In an example, the wireless device may determine the order based on the type of UL channel (eg, PRACH, PUCCH, PUSCH) and then based on the priority (or priority class). For example, the order may be: PRACH transmission with high priority on PCell or SPCell>PRACH transmission with low priority on PCell or SPCell>PUCCH transmission with HARQ-ACK and / or SR or PUSCH transmission with HARQ-ACK information with high priority>PUCCH transmission with HARQ-ACK and / or SR or PUSCH transmission with HARQ-ACK information with low priority>PUCCH transmission with CSI or PUSCH transmission with CSI>PUSCH transmission without UCI with high priority>PUCCH transmission with CSI or PUSCH transmission with CSI>PUSCH transmission without UCI with low priority>SRS transmission with aperiodic SRS>SRS transmission and / or PRACH transmission with semi-persistence and / or periodicity for SCell with high priority>SRS transmission with aperiodic SRS>SRS transmission and / or PRACH transmission with semi-persistence and / or periodicity for SCell with low priority.

[0478] In the same priority order and for operating with aggregation, the wireless device may prioritize power allocation for transmissions on the primary cell of the first CG (e.g., MCG) or the second CG (e.g., SCG) over transmissions on the secondary cell. The wireless device may prioritize power allocation for transmissions on the PCell over transmissions on the PSCell. In the same priority order and for operating with two UL carriers of the cell, the wireless device may prioritize power allocation for transmissions on the carrier on which the UE is configured to transmit PUCCH. If PUCCH is not configured for either of the two UL carriers of the cell, the wireless device may prioritize power allocation for transmissions on a non-supplementary UL carrier of the cell.

[0479] In an example, the wireless device may be associated with an MCG using an E-UTRA radio access and associated with an SCG using an NR radio access. The first base station or the second base station may configure one or more RRC messages, wherein the one or more RRC messages include a first transmission power threshold (P LTE ) for transmission on the MCG (e.g., p-MaxEUTRA). The first base station or the second base station may configure one or more RRC messages, wherein the one or more RRC messages include a first transmission power threshold (P NR ) for transmission (e.g., p-NR) in frequency range 1 (e.g., FR1) on the SCG. The one or more RRC messages may include an additional-Allowance, wherein the sum of the additional-Allowance and the first threshold of the SCG may determine the second power threshold. The wireless device may determine the power of one or more uplink channels in the CG based on the order rule described in the specification.

[0480] When the sum of the first transmission power threshold of the MCG and the second transmission power threshold of the SCG exceeds the UE allowed power allowed in frequency range 1 (e.g., p-UE-FR1), the wireless device may determine the transmission power of the SCG based on:

[0481] If the wireless device may have received a configuration of a reference TDD configuration for E-UTRA (LTE, e.g., tdm-patternConfig-r15), when a corresponding subframe on the MCG is a UL subframe based on the reference TDD configuration, the wireless device may reduce one or more uplink channels in a time slot of the SCG, wherein the corresponding subframe on the MCG is a subframe of the MCG corresponding to the time slot of the SCG, in response to the wireless device not supporting dynamic power sharing between LTE and NR. When the corresponding subframe on the MCG is not a UL subframe, the wireless device may determine the power of one or more uplink channels in a second time slot of the SCG based on the reference TDD configuration, based on a first transmission power threshold or a second transmission power threshold of the SCG, in response to the wireless device not supporting dynamic power sharing between LTE and NR. When the one or more uplink channels are associated with a first service or low priority (e.g., eMBB service), the wireless device may apply the first transmission power threshold of the SCG. When at least one UL channel is associated with a second service or high priority (e.g., URLLC service), the wireless device may apply the second transmission power threshold of the SCG.

[0482] When the wireless device supports dynamic power sharing between LTE and NR for EN-DC, the wireless device can reduce the transmission power of one or more uplink channels of the SCG in the time slot overlapping with the corresponding subframe of the MCG to meet the sum of the allocated transmission power on the MCG in the subframe and the allocated transmission power on the SCG in the time slot is lower than the UE allowed power.

[0483] In response to reducing the allocated transmission power on the SCG by more than XSCALE, the wireless device may reduce another uplink channel of the SCG. When the UL channel is associated with a second service or is associated with a high priority, the wireless device may not reduce the configured power on the UL channel from the one or more uplink channels. The configured power of the UL channel is limited by a second transmission power threshold of the SCG. If the sum of the configured powers on the MCG and the SCG exceeds the UE allowed power, where the configured power on the UL channel is not scaled, the wireless device may reduce one or more second UL channels on the corresponding subframe of the MCG, or reduce the power on the one or more second UL channels.

[0484] In an example, the wireless device may be associated with an MCG using NR radio access and associated with an SCG using E-UTRA radio access. The first base station or the second base station may configure a first transmission power threshold (e.g., p-NR) for the MCG. The first base station or the second base station may configure a first transmission power threshold (e.g., p-EUTRA) for the SCG. When the wireless device does not receive the TDD-UL-DL-ConfigurationCommon of the MCG, the wireless device may determine the transmission power of the SCG using the first transmission power threshold of the SCG. When the wireless device receives the TDD-UL-DL-ConfigurationCommon of the MCG, the wireless device determines the power of the SCG based on the following:

[0485] If at least one OFDM symbol of a time slot indicated as uplink or MCG with flexibility by TDD-UL-DL-ConfigurationCommon or TDD-UL-DL-ConfigDedicated overlaps with a subframe of an SCG, the wireless device may determine the transmission power of one or more UL channels of the subframe based on a first threshold of the SCG.

[0486] In other cases, the wireless device may determine the transmission power of the one or more UL channels of the subframe based on the UE allowed power.

[0487] The one or more RRC messages may include additional-Allowance, where the sum of the additional-Allowance and the first threshold of the MCG may determine the second power threshold. The wireless device may determine the power of one or more uplink channels in the CG based on the order rule described in the specification. When the sum of the first transmission power threshold of the MCG and the second transmission power threshold of the SCG exceeds the UE allowed power allowed in frequency range 1 (e.g., p-UE-FR1), the wireless device may determine the transmission power of the SCG based on the following:

[0488] If the wireless device may have received a configuration of a reference TDD configuration for E-UTRA of the SCG (LTE, e.g., tdm-patternConfig-r15), when the corresponding subframe on the SCG is a UL subframe based on the reference TDD configuration, the wireless device may reduce one or more uplink channels in a time slot of the MCG, wherein the corresponding subframe on the SCG is a subframe of the SCG corresponding to the time slot of the MCG, in response to the wireless device not supporting dynamic power sharing between LTE and NR. When the corresponding subframe on the SCG is not a UL subframe, the wireless device may determine the power of one or more uplink channels in a second time slot of the MCG based on the reference TDD configuration, based on a first transmission power threshold or a second transmission power threshold of the MCG, in response to the wireless device not supporting dynamic power sharing between LTE and NR. When the one or more uplink channels are associated with a first service or low priority (e.g., eMBB service), the wireless device may apply the first transmission power threshold of the MCG. When at least one UL channel is associated with a second service or high priority (e.g., URLLC service), the wireless device may apply the second transmission power threshold of the MCG.

[0489] When the wireless device supports dynamic power sharing between LTE and NR for EN-DC, the wireless device can reduce the transmission power of one or more uplink channels of the MCG in the time slot overlapping with the corresponding subframe of the SCG to meet the sum of the allocated transmission power on the SCG in the subframe and the allocated transmission power on the MCG in the time slot is lower than the UE allowed power.

[0490] In response to reducing the allocated transmission power on the MCG by more than XSCALE, the wireless device may reduce the additional uplink channels of the MCG. When the UL channel is associated with a second service or is associated with a high priority, the wireless device may not reduce the configured power on the UL channel from the one or more uplink channels. The configured power of the UL channel is limited by a second transmission power threshold of the MCG. If the sum of the configured powers on the MCG and the SCG exceeds the UE allowed power and the configured power on the UL channel is not scaled, the wireless device may reduce one or more second UL channels on the corresponding subframe of the SCG, or reduce the power on the one or more second UL channels.

[0491] Fig.24A flow chart for power determination is shown. The wireless device may determine the power of one or more uplink channels of a CG at a time (e.g., OFDM symbol i of time slot n). The wireless device may select a first uplink channel as a first-ranked UL channel from the one or more uplink channels based on one or more priority rules. When the transmission power of the first-ranked UL channel (e.g., the first uplink channel) is higher than a first threshold of the CG and the first uplink channel is associated with a high priority, the wireless device may apply a second transmission power threshold when determining the power on the first uplink channel. Otherwise, the wireless device may apply the first transmission power threshold when determining the power on the first uplink channel. The wireless device may transmit the first uplink channel based on the determined power.

[0492] Fig.25 A flow chart for power determination is shown. The wireless device may determine the power of one or more uplink channels of a CG at a time (e.g., OFDM symbol i of time slot n). The wireless device may select a first uplink channel as a first-ordered UL channel from the one or more uplink channels based on one or more priority rules. When the transmission power of the first-ordered UL channel (e.g., the first uplink channel) is higher than the first threshold of the CG and has not yet reached the configured duty cycle (e.g., the high power of the first threshold that has been used is less than the configured duty cycle), the wireless device may apply a second transmission power threshold when determining the power on the first uplink channel. Otherwise, the wireless device may apply the first transmission power threshold when determining the power on the first uplink channel. The wireless device may transmit the first uplink channel based on the determined power.

[0493] The wireless device may receive one or more radio resource control (RRC) messages. The one or more RRC messages may indicate a first transmission power threshold for a first cell group and a second transmission power threshold for the first cell group. The wireless device may determine the power of one or more uplink channels of the first cell group based on an order. The wireless device may determine a first uplink channel based on the order, the first uplink channel being the first ranked UL channel among the one or more uplink channels. The wireless device may select one of the first transmission power threshold and the second transmission power threshold based on a priority category of the first uplink channel. For example, when the priority category of the first uplink channel is a first priority, the wireless device may select the first transmission power threshold. For example, when the priority category of the first uplink channel is a second priority, the wireless device may select the second transmission power threshold. The wireless device may determine the transmission power of the first uplink channel based on one or more power parameters, path loss, a scheduling DCI of the first uplink channel (if available), or a configured license configuration corresponding to the first uplink channel, and the selected power threshold. The wireless device may transmit the first uplink channel using the determined transmission power.

[0494] The wireless device may determine the priority category of the first uplink channel based on the RNTI corresponding to the DCI that schedules the first uplink channel.
