Description

TECHNICAL FIELD

[0001] The present disclosure relates to wireless communications, and more particularly to user equipment (UE), base stations, processors, and methods for channel state information (CSI) reporting (e.g., for layer 1 / layer 2 (L1 / L2) triggered mobility (LTM)). BACKGROUND

[0002] A wireless communication system can include one or more network communication devices (such as a base station), which can also be referred to as an eNodeB (eNB), a next generation NodeB (gNB), or other suitable terminology. Each network communication device (such as a base station) can support wireless communication for one or more user communication devices, which can also be referred to as user equipment (UE) or other suitable terminology. A wireless communication system can support wireless communication with one or more user communication devices by utilizing resources (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers)) of the wireless communication system. Moreover, a wireless communication system can support wireless communication across various radio access technologies, including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, and other suitable radio access technologies beyond 5G (e.g., sixth generation (6G)).

[0003] In 3GPP, LTM is proposed to reduce handover latency compared to layer-based mobility. One point in LTM is to perform measurements on neighboring cells and report the measurement results in layer 1. Currently, only some candidate cells’ SSBs can be configured for UE to perform L1 measurements, and the UE shall report the measurement results as a type of CSI via uplink control information (UCI) reporting framework. Moreover, periodic CSI reporting on PUCCH, semi-persistent CSI reporting on PUCCH, semi-persistent CSI reporting on PUSCH, and aperiodic CSI reporting on PUSCH shall be supported, so there are still some open issues related to CSI reporting to be studied in the future.

[0067] In Rel-17, priority rules for CSI reporting are specified in TS 38.214 v17.4.0. For two overlapping PUSCHs carrying CSI reports, according to Clause 9 in [6, TS 38.213], the priority rules apply to physical channels with the same priority index.

[0068] A CSI report is associated with a priority value calculated as follows: wherein y the value of can indicate the reporting type of the CSI report, y = 0 can indicate an aperiodic CSI report to be carried on PUSCH, y = 1 can indicate a semi-persistent CSI report to be carried on PUSCH, y = 2 can indicate a semi-persistent CSI report to be carried on PUCCH, y = 3 can indicate a periodic CSI report to be carried on PUCCH. k the value of can indicate whether the CSI report carries L1 reference signal received power (RSRP) or L1 signal to interference plus noise ratio (SINR), and k= 0 can indicate a CSI report carrying L1-RSRP or L1-SINR, and k = 1 can indicate a CSI report not carrying L1-RSRP or L1-SINR. c is a serving cell index, N cells is a value of a higher layer parameter maxNrofServingCells , which refers to the maximum number of serving cells configured for a UE. s is a report configuration identifier (ID) of a CSI report configuration used for the CSI report (i.e., reportConfigID ), and M s is a value of a higher layer parameter maxNrofCSI-ReportConfigurations , which refers to the maximum number of CSI report configurations configured for a UE in a serving cell.

[0069] If the priority value of a first CSI report calculated as above is lower than the priority value of a second report, the first CSI report is said to have priority over the second CSI report.

[0070] If the time occupancy of the physical channel scheduled to carry two CSI reports overlap in at least one OFDM symbol and are transmitted on the same carrier, the two CSI reports are said to collide. In case a UE is configured to transmit two colliding CSI reports, if the y values of the two CSI reports are different, the following rules apply, but one y value is 2 (for CSI reports transmitted on PUSCH as described in clause 5.2.3) and the other y value is 3 (for CSI reports transmitted on PUCCH as described in clause 5.2.4) except. The UE shall not transmit the CSI report with the higher priority value. Otherwise, the two CSI reports will be multiplexed or one of the CSI reports is dropped based on the priority value as described in clause 9.2.5.2 in [6, TS 38.213].

[0071] If a semi-persistent CSI report to be carried on PUSCH overlaps in time with PUSCH data transmission in one or more symbols on the same carrier, and if the earliest symbol start time of these PUSCH channels is not earlier than N2+d 2,1 symbols after the last symbol of the DCI scheduling the PUSCH, where d 2,1 is the maximum value of d 2,1 associated with the PUSCH carrying the semi-persistent CSI report and the PUSCH with data transmission, the UE shall not transmit the CSI report. Otherwise, if the timeline requirement is not met, this is an error case.

[0072] If a UE is to transmit a first PUSCH including a semi-persistent CSI report and a second PUSCH including an uplink (UL) shared channel (SCH) on the same carrier, and the first PUSCH transmission is to overlap in time with the second PUSCH transmission, the UE does not transmit the first PUSCH but transmits the second PUSCH. When at least one of the first PUSCH transmission or the second PUSCH transmission is in response to a DCI format detection by the UE, the UE expects the first PUSCH transmission and the second PUSCH transmission to satisfy the above timing conditions for overlapping PUSCH transmissions in time.

[0073] Further, the activation / deactivation MAC CE for semi-persistent (SP) CSI reporting on PUCCH is specified in TS 38.321 v17.4.0. The activation / deactivation MAC CE for SP CSI reporting on PUCCH is identified by a MAC subheader with a logical channel identity (LCID). Figure 2 An example of the activation / deactivation MAC CE for semi-persistent CSI reporting on PUCCH associated with aspects of the present disclosure is illustrated. As shown in Figure 2 The MAC CE has a fixed size of 16 bits with the following fields, as shown in - Serving Cell ID: This field indicates the identity of the serving cell to which the MAC CE applies. The length of this field is 5 bits; - BWP ID: This field indicates the UL bandwidth part (BWP) to which the MAC CE applies as a codepoint of the DCI Bandwidth part indicator fields specified in TS 38.212 [9]. The length of the BWP ID field is 2 bits; - S i : This field indicates the activation / deactivation status of the semi-persistent CSI reporting configuration within the list as described in TS 38.331 [5]. S0 refers to the reporting configuration that includes the PUCCH resource for SP CSI reporting in the indicated BWP and has the lowest csi-ReportConfigToAddModList (i.e., the lowest semiPersistentOnPUCCH ), S1 refers to the reporting configuration that includes the PUCCH resource for SP CSI reporting in the indicated BWP and has the second lowest CSI-ReportConfigId (i.e., the second lowest csi-ReportConfigToAddModList ), and so on. If the number of reporting configurations within the list with Type set to CSI- ReportConfigId and so on. If the number of reporting configurations within the list with Type set to semiPersistentOnPUCCH i field. S i ​The field is set to 1 to indicate that the corresponding semi-persistent CSI report configuration i should be activated. i The field is set to 0 to indicate that the corresponding semi-persistent CSI report configuration i should be deactivated. - R: Reserved bit, set to 0.

[0074] LTM is specified in NR Rel-18 to reduce the handover latency compared to layer 3 based mobility. One of the key points in LTM is to perform measurements on neighboring cells and report the measurement results in layer 1. The MAC layer can send a cell handover command through a MAC CE to inform the UE to handover to another cell. In Rel-18, only SSBs of some candidate cells can be configured for the UE to perform L1 measurements, and the UE shall report the measurement results as a type of CSI via the uplink control information (UCI) reporting framework. Periodic CSI reporting on physical uplink control channel (PUCCH), semi-persistent CSI reporting on PUCCH, semi-persistent CSI reporting on PUSCH, and aperiodic CSI reporting on physical uplink shared channel (PUSCH) shall also be supported for LTM. RAN1 and RAN2 have discussed the RRC signaling structure to support CSI reporting for LTM, and provided two approaches to additionally down-select. One approach is to reuse CSI-ReportConfig information elements (IEs) and make necessary enhancements, while the other approach is to introduce another LTM-CSI- ReportConfig IE for dedicated configuration of CSI reporting for LTM. Approach 1 has less impact on RAN1, as the legacy CSI reporting framework based on CSI-ReportConfigId can be reused, but the corresponding RAN2 impact can be more. But for approach 2, there is still a lot of work to do, as the configuration of CSI reporting for LTM can be totally different from legacy CSI reporting, especially for LTM scenarios with inter-frequency measurements, the new IE is more suitable for LTM evaluation in future releases.

[0075] In addition, similar to the legacy CSI reporting on PUCCH (i.e., CSI reporting without LTM) described above, a MAC CE can be used for the activation of one or more CSI reports for LTM. To save MAC CE overhead, the legacy activation / deactivation MAC CE for SP CSI reporting on PUCCH can be reused and necessary enhancements are made. According to the high layer signaling design for aperiodic triggering, one or more LTM-CSI-ReportConfig can be mapped to CSI- AperiodicTriggerState DCI formats 0_1 and 0_2 andCSI-AperiodicTriggerState The legacy CSI request field in DCI format 0_0 / 0_1 / 1_0 / 1_1. LTM-CSI-ReportConfig The legacy activation / deactivation mechanism can be reused for semi-persistent CSI reporting for LTM on PUSCH by mapping one or more CSI-SemiPersistentOnPUSCH-TriggerState to CSI-ReportConfig to a set of CSI reports corresponding to LTM-CSI-ReportConfig to a set of CSI reports corresponding to Figure 2 Detailed MAC CE format and corresponding behavior are provided in

[0076] The present disclosure proposes a solution to support CSI reporting for LTM. In this solution, some priority rules for CSI reporting for LTM and legacy CSI reporting are proposed, especially for the case that CSI reporting for LTM is configured by new LTM-CSI-ReportConfig IE. On the other hand, a method to reuse the legacy activation / deactivation MAC CE for SP CSI on PUCCH to activate SP CSI reporting on PUCCH for LTM is also provided in this disclosure. By implementing the solution in this application, CSI reporting for LTM and legacy CSI reporting are compatible, and for LTM, various CSI reporting such as periodic CSI reporting on PUCCH, semi-persistent CSI reporting on PUCCH, semi-persistent CSI reporting on PUSCH and aperiodic CSI reporting on PUSCH can also be supported.

[0077] Aspects of the disclosure are described in the context of a wireless communication system.

[0078] Figure 1An example of a wireless communications system 100 that supports CSI reporting in accordance with aspects of the present disclosure is illustrated. The wireless communications system 100 can include one or more network entities 102 (also referred to as network equipment (NE)), one or more UEs 104, a core network 106, and a packet data network 108. The wireless communications system 100 can support various radio access technologies. In some implementations, the wireless communications system 100 can be a 4G network, such as an LTE network or a LTE-Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 can be a 5G network, such as an NR network. In other implementations, the wireless communications system 100 can be a combination of 4G and 5G networks, or other suitable radio access technologies, including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20. The wireless communications system 100 can support radio access technologies other than 5G. Further, the wireless communications system 100 can support technologies such as time division multiple access (TDMA), frequency division multiple access (FDMA), or code division multiple access (CDMA).

[0079] The one or more network entities 102 can be dispersed throughout the geographic region to form the wireless communications system 100. One or more of the network entities 102 described herein can be, or include, or can be referred to as, a network node, a base station, a network element, a radio access network (RAN), a base transceiver station, an access point, a NodeB, an eNodeB (eNB), a next generation NodeB (gNB), or other suitable terminology. The network entities 102 and the UEs 104 can communicate via communication links 110, which can be wireless or wired connections. For example, the network entities 102 and the UEs 104 can perform wireless communications (e.g., receive signaling, transmit signaling) over a Uu interface.

[0080] The network entity 102 can provide a geographic coverage area 112 for which the network entity 102 can support service (e.g., voice, video, packet data, messaging, broadcast, etc.) to one or more UEs 104 within the geographic coverage area 112. For example, the network entity 102 and UE 104 can support wireless communication of signals associated with service (e.g., voice, video, packet data, messaging, broadcast, etc.) in accordance with one or more wireless access technologies. In some implementations, the network entity 102 can be mobile, such as a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies can overlap, but different geographic coverage areas 112 can be associated with different network entities 102. Information and signals described herein can be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that can be referenced throughout the description can be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0081] The one or more UEs 104 can be dispersed throughout the geographic region of the wireless communication system 100. A UE 104 can include or can be referred to as a mobile device, wireless device, remote device, remote unit, handset, subscriber device, or some other suitable terminology. In some implementations, a UE 104 can be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, a UE 104 can be referred to as an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples. In some implementations, a UE 104 can be static or have limited mobility in the wireless communication system 100. In some other implementations, a UE 104 can have mobility in the wireless communication system 100.

[0082] The one or more UEs 104 can be devices in different forms or having different capabilities. Figure 1 Some examples of UEs 104 are illustrated in FIG. 1. A UE 104 can be capable of communicating with various types of devices, such as the network entity 102, other UEs 104, or network devices (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network device), as shown in FIG. 1. Additionally or alternatively, a UE 104 can support communication with other UEs 104 or network entities 102 that can act as relays in the wireless communication system 100. Figure 1 Some examples of UEs 104 are illustrated in FIG. 1. A UE 104 can be capable of communicating with various types of devices, such as the network entity 102, other UEs 104, or network devices (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network device), as shown in FIG. 1. Additionally or alternatively, a UE 104 can support communication with other UEs 104 or network entities 102 that can act as relays in the wireless communication system 100.

[0083] UE 104 can also support direct wireless communication with other UE 104s via communication link 114. For example, UE 104 can support direct wireless communication with another UE 104 via a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular V2X deployments, communication link 114 may be referred to as a sidechain. For example, UE 104 can support direct wireless communication with another UE 104 via a PC5 interface.

[0084] Network entity 102 may support communication with core network 106 or with another network entity 102, or both. For example, network entity 102 may interface with core network 106 via one or more backhaul links 116 (e.g., via S1, N2, N2, or another network interface). Network entities 102 may communicate with each other via backhaul links 116 (e.g., via X2, Xn, or another network interface). In some implementations, network entities 102 may communicate directly with each other (e.g., between network entities 102). In some other implementations, network entities 102 may communicate with each other or indirectly (e.g., via core network 106). In some implementations, one or more network entities 102 may include sub-components, such as access network entities, which may be examples of access node controllers (ANCs). An ANC may communicate with one or more UEs 104 via one or more other access network transport entities (which may be referred to as radio headends, smart radio headends, or transmit-receive points (TRPs)).

[0085] In some implementations, network entity 102 can be configured with a decomposed architecture that can utilize protocol stacks physically or logically distributed across two or more network entities 102, such as an Integrated Access Backhaul (IAB) network, an Open Radio Access Network (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a Virtualized RAN (vRAN) (e.g., a Cloud RAN (C-RAN)). For example, network entity 102 may include one or more of the following: CU, DU, Radio Unit (RU), RAN Intelligent Controller (RIC) (e.g., near real-time RIC, non-real-time RIC), Service Management and Orchestration (SMO) system, or any combination thereof.

[0086] A RU can also be referred to as a radio head, intelligent radio head, remote radio head (RRH), remote radio unit (RRU), or transmission reception point (TRP). In a disaggregated RAN architecture, one or more components of the network entity 102 can be co-located, or one or more components of the network entity 102 can be located at distributed locations (e.g., separate physical locations). In some implementations, one or more network entities 102 of a disaggregated RAN architecture can be implemented as virtual units (e.g., virtual CUs (VCUs), virtual DUs (VDUs), virtual RUs (VRUs)).

[0087] The functional split between the CU, the DU, and the RU can be flexible and can support different functions depending on the functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combination thereof) performed at the CU, the DU, or the RU. For example, a functional split of a protocol stack can be employed between the CU and the DU such that the CU can support one or more layers of the protocol stack and the DU can support one or more different layers of the protocol stack. In some implementations, the CU can host upper layer protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functions and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU can be connected to one or more DUs or RUs, and the one or more DUs or RUs can host lower protocol layers, such as layer 1 (LI) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functions and signaling, and each can be controlled at least in part by the CU 160.

[0088] Additionally or alternatively, a functional split of a protocol stack can be employed between the DU and the RU such that the DU can support one or more layers of the protocol stack and the RU can support one or more different layers of the protocol stack. The DU can support one or more different cells (e.g., via one or more RUs). In some implementations, the functional split between the CU and the DU or between the DU and the RU can be within a protocol layer (e.g., some functions for a protocol layer can be performed by one of the CU, the DU, or the RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU).

[0089] A CU can be further split in function into a CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU can be connected to one or more DUs via a midhaul communication link (e.g., Fl, Fl-c, Fl-u), and a DU can be connected to one or more RUs via a front-haul communication link (e.g., open front-haul (FH) interface). In some implementations, a midhaul or front-haul communication link can be implemented according to an interface (e.g., channel) between layers of a protocol stack supported by respective network entities 102 communicating via such a communication link.

[0090] The core network 106 can support user authentication, access authorization, tracking, connection, and other access, routing, or mobility functions. The core network 106 can be an evolved packet core (EPC) or 5G core (5GC), which can include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and a user plane entity that routes packets or interconnections to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). In some implementations, the control plane entity can manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management (e.g., data bearer, signaling bearer, etc.) for one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.

[0091] The core network 106 can communicate with a packet data network 108 through one or more backhaul links 116 (e.g., via SI, N2, N3, or another network interface). The packet data network 108 can include an application server 118. In some implementations, the one or more UEs 104 can communicate with the application server 118 through the core network 106. A UE 104 can establish a session (e.g., a protocol data unit (PDU) session, etc.) with the core network 106 via a network entity 102. The core network 106 can use the established session (e.g., an established PDU session) to route traffic (e.g., control information, data, etc.) between the UE 104 and the application server 118. A PDU session can be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106).

[0092] In the wireless communication system 100, the network entity 102 and the UE 104 can perform various operations (e.g., wireless communications) using resources (e.g., time resources (e.g., symbols, slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers)) of the wireless communication system 100. In some implementations, the network entity 102 and the UE 104 can support different resource structures. For example, the network entity 102 and the UE 104 can support different frame structures. In some implementations, such as in 4G, the network entity 102 and the UE 104 can support a single frame structure. In some other implementations, such as in 5G and other suitable radio access technologies, the network entity 102 and the UE 104 can support various frame structures (i.e., multiple frame structures). The network entity 102 and the UE 104 can support various frame structures based on one or more numerologies.

[0093] One or more numerologies can be supported in the wireless communication system 100, and a numerology can include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., a normal cyclic prefix (NCP)) can be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., NCP = 0) associated with the first subcarrier spacing (e.g., 15 kHz) can utilize one slot per subframe. A second numerology (e.g., an extended cyclic prefix (ECP)) can be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., ECP = 1) can be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., ECP = 2) can be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., ECP = 3) can be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix. A sixth numerology (e.g., ECP = 4) can be associated with a sixth subcarrier spacing (e.g., 480 kHz) and a normal cyclic prefix. μ μ The first numerology (e.g., NCP = 0) associated with the first subcarrier spacing (e.g., 15 kHz) can utilize one slot per subframe. The second numerology (e.g., ECP = 1) associated with the second subcarrier spacing (e.g., 30 kHz) can utilize two slots per subframe. μ The third numerology (e.g., ECP = 2) associated with the third subcarrier spacing (e.g., 60 kHz) can utilize four slots per subframe. The fourth numerology (e.g., ECP = 3) associated with the fourth subcarrier spacing (e.g., 120 kHz) can utilize eight slots per subframe. The fifth numerology (e.g., ECP = 4) associated with the fifth subcarrier spacing (e.g., 240 kHz) can utilize sixteen slots per subframe. μ The third numerology (e.g., ECP = 2) associated with the third subcarrier spacing (e.g., 60 kHz) can utilize four slots per subframe. The fourth numerology (e.g., ECP = 3) associated with the fourth subcarrier spacing (e.g., 120 kHz) can utilize eight slots per subframe. The fifth numerology (e.g., ECP = 4) associated with the fifth subcarrier spacing (e.g., 240 kHz) can utilize sixteen slots per subframe. μ The third numerology (e.g., ECP = 2) associated with the third subcarrier spacing (e.g., 60 kHz) can utilize four slots per subframe. The fourth numerology (e.g., ECP = 3) associated with the fourth subcarrier spacing (e.g., 120 kHz) can utilize eight slots per subframe. The fifth numerology (e.g., ECP = 4) associated with the fifth subcarrier spacing (e.g., 240 kHz) can utilize sixteen slots per subframe. μ The third numerology (e.g., ECP = 2) associated with the third subcarrier spacing (e.g., 60 kHz) can utilize four slots per subframe. The fourth numerology (e.g., ECP = 3) associated with the fourth subcarrier spacing (e.g., 120 kHz) can utilize eight slots per subframe. The fifth numerology (e.g., ECP = 4) associated with the fifth subcarrier spacing (e.g., 240 kHz) can utilize sixteen slots per subframe.

[0094] Time intervals of resources (e.g., communication resources) can be organized as frames, each frame having a duration of, for example, 10 milliseconds (ms). In some implementations, each frame can include multiple subframes. For example, each frame can include 10 subframes, and each subframe can have a duration of, for example, 1 ms. In some implementations, each frame can have a same duration. In some implementations, each subframe of a frame can have a same duration.

[0095] ​Additionally or alternatively, time intervals of resources (e.g., communication resources) can be organized as slots, for example. A subframe can include a number (e.g., quantity) of slots. The number of slots in each subframe can also depend on the one or more numerologies supported in the wireless communication system 100. For example, a first numerology, a second numerology, a third numerology, a fourth numerology, and a fifth numerology (i.e., μ = 0, μ = 1, μ = 2, μ = 3, μ = 4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz can utilize one slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot can include a number (e.g., quantity) of symbols (e.g., OFDM symbols). In some implementations, the number (e.g., quantity) of slots for a subframe can depend on the numerology. For a normal cyclic prefix, a slot can include 14 symbols. For an extended cyclic prefix (e.g., applicable to 60 kHz subcarrier spacing), a slot can include 12 symbols. For normal and extended cyclic prefixes, the relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame can depend on the numerology. It will be understood that reference to the first numerology (e.g., μ = 0) associated with a first subcarrier spacing (e.g., 15 kHz) can be used interchangeably between subframes and slots.

[0096] In the wireless communication system 100, the electromagnetic (EM) spectrum can be split into various classes, bands, frequency channels, and so forth based on frequency or wavelength. For example, the wireless communication system 100 can support one or more operating bands, such as frequency range designations FR1 (410 MHz - 7.125 GHz), FR2 (24.25 GHz - 52.6 GHz), FR3 (7.125 GHz - 24.25 GHz), FR4 (52.6 GHz - 114.25 GHz), FR4a or FR4-1 (52.6 GHz - 71 GHz), and FR5 (114.25 GHz - 300 GHz). In some implementations, the network entity 102 and the UE 104 can perform wireless communication on one or more operating bands. In some implementations, FR1 can be used by the network entity 102 and the UE 104, and other devices or apparatuses, for cellular communications traffic (e.g., control information, data). In some implementations, FR2 can be used by the network entity 102 and the UE 104, and other devices or apparatuses, for short range, high data rate capabilities.

[0097] FR1 can be associated with one or more numerologies (e.g., at least three numerologies). For example, FR1 can be associated with: a first numerology (e.g., μ = 0) that includes a subcarrier spacing of 15 kHz; a second numerology (e.g., μ = 1) that includes a subcarrier spacing of 30 kHz; and a third numerology (e.g., μ = 2) that includes a subcarrier spacing of 60 kHz. FR2 can be associated with one or more numerologies (e.g., at least two numerologies). For example, FR2 can be associated with: the third numerology (e.g., μ = 2) that includes a subcarrier spacing of 60 kHz; and a fourth numerology (e.g., μ = 3) that includes a subcarrier spacing of 120 kHz.

[0098] Figure 3 FIG. illustrates an example of a signaling procedure 300 for CSI reporting, according to aspects of the present disclosure.

[0099] As shown in Figure 3 At step 302, the base station 102 determines one or more channel state information (CSI) reporting configurations. Then at step 304, the base station 102 transmits the one or more CSI reporting configurations to a user equipment (UE) 102 for determining a priority of a CSI report by the UE 104. In some embodiments of the present disclosure, the base station 102 can be a source base station for LTM.

[0100] At step 306, the UE 104 receives the one or more CSI reporting configurations, and at step 308, determines a priority of a CSI report based at least on the CSI reporting configurations. Herein, the CSI report can refer to a CSI report to be transmitted to the base station 102.

[0101] In some embodiments of the present disclosure, the priority of a CSI report for LTM determined based on the CSI reporting configurations can be higher than the priority of a CSI report for non-LTM (which can also be referred to as a legacy CSI report) determined based on the CSI reporting configurations, because the CSI report for LTM is more relevant to mobility decision making. Moreover, for LTM, all possible reporting time domain behaviors are supported, including aperiodic, semi-persistent CSI reporting on PUSCH, semi-persistent CSI reporting on PUCCH, and periodic.

[0102] Similar to the legacy CSI reporting, the priority of the CSI reporting (including the CSI reporting for non-LTM and the CSI reporting for LTM) can be determined based on the priority value of the CSI reporting. The UE 104 can determine the priority value of each CSI reporting based on at least the reporting configuration identifier (ID) of the CSI reporting configuration for the CSI reporting. The procedure of determining the priority value and the priority of the CSI reporting (including the CSI reporting for non-LTM and the CSI reporting for LTM) is explained in detail below.

[0103] In some implementations, the CSI reporting configuration for LTM and the CSI reporting configuration for non-LTM can use the same high layer information element, e.g., the legacy CSI reporting configuration (i.e., the CSI reporting configuration for non-LTM) for the legacy CSI reporting (i.e., the CSI reporting for non-LTM) can be reused as the CSI reporting configuration for LTM, i.e., the CSI reporting for LTM can be configured by the legacy CSI reporting configuration CSI-ReportConfig CSI-ReportConfig CSI- ReportConfig The CSI reporting for LTM can be identified by being configured with the LTM reporting content information (e.g., the high layer parameter LTM-ReportContent

[0104] In addition, in the case that the CSI reporting for LTM is configured by the legacy CSI-ReportConfig configuration, the UE 104 generally expects the CSI reporting for LTM to have higher priority than the legacy CSI reporting with the NR Rel-17 CSI priority rule as described above. Based on the priority rule as described above, the lower the priority value, the higher the priority, thus the reporting configuration ID of each CSI reporting configuration for LTM can be set to be smaller than the reporting configuration ID of each CSI reporting configuration for non-LTM. For example, the CSI-ReportConfig for the CSI reporting for LTM can be set to be smaller than the CSI- ReportConfig with smaller CSI-ReportConfigId . Thus, based on equation (1), the priority rule calculated for the CSI reporting for LTM will be lower than the priority rule calculated for the legacy CSI reporting, and thus, the priority of the CSI reporting for LTM will be higher than the priority of the legacy CSI reporting.

[0105] In some embodiments of the present disclosure, in the case that the CSI reporting for LTM is also configured by the legacy CSI-ReportConfig ​​​In the case of the CSI reporting for LTM is configured, the priority value of the CSI reporting for LTM can be calculated in the same way as the legacy CSI reporting. For example, for a CSI reporting (which can be a CSI reporting for LTM or a legacy CSI reporting), in addition to the reporting configuration ID of the CSI reporting configuration for the CSI reporting, the priority value of the CSI reporting can be determined based on the following: a type indication value indicating the reporting type of the CSI reporting, the reporting type can be one of the following: aperiodic, semi-persistent on PUSCH, semi-persistent on PUCCH, or periodic; a measurement indication value indicating whether the CSI reporting carries L1-RSRP or L1-SINR; a serving cell index for the UE 104; a maximum number of serving cells configured for the UE; and a maximum number of CSI reporting configurations for the serving cell. An example calculation of the priority value of the CSI reporting for this case can be represented as:

[0106]

[0107] In Equation (2) similar to Equation (1), y the value of can indicate the reporting type of the CSI reporting, for example, y = 0 can indicate the aperiodic CSI report(s) to be carried on PUSCH, y = 1 can indicate the semi-persistent CSI report(s) to be carried on PUSCH, y = 2 can indicate the semi-persistent CSI report(s) to be carried on PUCCH, and y = 3 can indicate the periodic CSI report(s) to be carried on PUCCH. k the value of can indicate whether the CSI reporting carries L1-RSRP or L1-SINR, for example, k = 0 can indicate the CSI report(s) carrying L1-RSRP or L1-SINR, k = 1 can indicate the CSI report(s) not carrying L1-RSRP or L1-SINR. c is the serving cell index, N cells is the value of the higher layer parameter maxNrofServingCells which refers to the maximum number of serving cells configured for the UE. s is the reporting configuration identifier (ID) of the CSI reporting configuration for the CSI reporting (i.e., reportConfigID ), and M s is the value of the higher layer parameter maxNrofCSI-ReportConfigurations which refers to the maximum number of CSI reporting configurations configured for the UE in the serving cell. The values of these parameters are just examples, other different values can be used as needed.

[0108] In some implementations, the CSI reporting for LTM is configured by legacy CSI-ReportConfig configurations, the UE 104 can perform at least one of: receiving, via the transceiver and from the source base station 102, a first DCI containing a non-zero CSI request field, each codepoint of the non-zero CSI request field being mapped to a CSI aperiodic trigger state associated with one or more CSI reporting configurations for LTM to trigger aperiodic CSI reporting for LTM; receiving, via the transceiver and from the source base station 102, a second DCI containing a CSI request field, each codepoint of the CSI request field contained by the second DCI being mapped to a CSI aperiodic trigger state associated with one or more CSI reporting configurations for non-LTM to trigger aperiodic CSI reporting for non-LTM; receiving, via the transceiver and from the source base station 102, a third DCI containing a CSI request field, each codepoint of the CSI request field contained by the third DCI being mapped to a CSI semi-persistent trigger state associated with one or more CSI reporting configurations for LTM to trigger semi-persistent CSI reporting on PUSCH for LTM; receiving, via the transceiver and from the source base station 102, a fourth DCI containing a CSI request field, each codepoint of the CSI request field contained by the fourth DCI being mapped to a CSI semi-persistent trigger state associated with one or more CSI reporting configurations for non-LTM to trigger semi-persistent CSI reporting on PUSCH for non-LTM.

[0109] For example, in case the CSI reporting for LTM is configured by legacy CSI-ReportConfig configurations, the aperiodic CSI reporting for LTM can be triggered by a non-zero CSI request field in DCI, and each CSI request codepoint of the CSI request field is mapped with one or more CSI-ReportConfig associated. CSI-AperiodicTriggerState In some embodiments of the present disclosure, considering that the CSI reporting for LTM can need inter-frequency measurements with gaps, each CSI-AperiodicTriggerState can only be associated with one or more CSI- ReportConfig associated for the CSI reporting for LTM, or with one or more CSI-ReportConfig associated for legacy CSI reporting. Similarly, the semi-persistent CSI reporting on PUSCH for LTM can be triggered by a DCI format containing a CSI request field scrambled with SP-CSI-RNTI by mapping CSI-SemiPersistentOnPUSCH-TriggerState to CSI request field codepoints, and similar to the aperiodic CSI triggering as mentioned before, each CSI- SemiPersistentOnPUSCH-TriggerStateonly one or more CSI reports for LTM CSI- ReportConfig or one or more CSI reports for legacy CSI CSI-ReportConfig associated. In addition, semi-persistent (SP) CSI reporting on PUCCH for LTM can be activated by a MAC CE containing an activation / deactivation status indicating each SP CSI reporting configuration on PUCCH and a bitmap supporting additional SP CSI reporting on PUCCH for LTM, the length of the bitmap can be increased compared to legacy CSI reporting. For example, the length of the bitmap for legacy CSI reporting can be 4 bits, and the length of the bitmap for CSI reporting for LTM can be increased from 4 bits to 8 bits.

[0110] In some implementations, the CSI reporting configuration transmitted from the base station 102 can include different types of CSI reporting configurations. For example, the CSI reporting configuration can include one or more first CSI reporting configurations and one or more second CSI reporting configurations, the first and second CSI reporting configurations can be different types of CSI reporting configurations, and the reporting configuration ID of the first CSI reporting configuration is independent of the reporting configuration ID of the second CSI reporting configuration, for example, the reporting configuration ID of the first CSI reporting configuration can be a value with a range from 0 to (the maximum number of first CSI reporting configurations) - 1, and similarly, the reporting configuration ID of the second CSI reporting configuration can be a value with a range from 0 to (the maximum number of second CSI reporting configurations) - 1. The first CSI reporting configuration (e.g., LTM-CSI-ReportConfig , which can be a dedicated CSI reporting configuration for LTM) can be used to configure at least one CSI report for LTM, and the second CSI reporting configuration (e.g. CSI-ReportConfig ) can be used to configure at least one CSI report for non-LTM. The process of determining the priority value and priority of the CSI report for non-LTM and the CSI report for LTM in this case is explained in detail below.

[0111] In the case where the CSI report for LTM is configured by the first CSI reporting configuration (e.g., LTM-CSI-ReportConfig ) and the CSI report for non-LTM is configured by the second CSI reporting configuration (e.g., CSI-ReportConfigIn case the CSI reporting (which can be a CSI reporting for LTM or a legacy CSI reporting) is configured, in addition to the reporting configuration ID of the CSI reporting configuration for the CSI reporting, the priority value of the CSI reporting can be determined based on the following: a type indication value indicating the reporting type of the CSI reporting, the reporting type can be one of the following: aperiodic, semi-persistent on PUSCH, semi-persistent on PUCCH, or periodic; a measurement indication value indicating whether the CSI reporting carries L1-RSRP or L1-SINR; a sum value of the maximum number of first CSI reporting configurations and the maximum number of second CSI reporting configurations configured for the UE of a serving cell; a serving cell index for the UE 104; and a maximum number of serving cells configured for the UE. In this case, the priority value of the CSI reporting for non-LTM and the CSI reporting for LTM can be based on these parameters, but in different ways. For example, the priority value of the CSI reporting for non-LTM can be determined based on the following equation (3) and for the CSI reporting corresponding to CSI-ReportConfig . The priority value of the CSI reporting for LTM can be determined based on the following equation (4) and for the CSI reporting corresponding to LTM-CSI-ReportConfig . .

[0112] In the above equations, y The value of y = 0 can indicate the aperiodic CSI report(s) to be carried on PUSCH, y = 1 can indicate the semi-persistent CSI report(s) to be carried on PUSCH, y = 2 can indicate the semi-persistent CSI report(s) to be carried on PUCCH, y = 3 can indicate the periodic CSI report(s) to be carried on PUCCH. k The value of k = 0 can indicate the CSI report(s) carrying L1-RSRP or L1-SINR, k = 1 can indicate the CSI report(s) not carrying L1-RSRP or L1-SINR. c is the serving cell index, and N cells is the value of the higher layer parameter maxNrofServingCells , which is the maximum number of serving cells for the UE.s 1 is a reporting configuration identifier (ID) of the second CSI report configuration (i.e., reportConfigID ), and s 2 is a reporting configuration identifier (ID) of the second CSI report configuration (i.e., reportConfigID ), and M s is the sum of the value of the higher layer parameter maxNrofCSI-ReportConfigurations and the value of the higher layer parameter maxNrofLTM-CSI-ReportConfigurations , i.e., the sum value of the maximum number of the first CSI report configuration for the UE of the serving cell and the maximum number of the second CSI report configuration. The values of these parameters are only examples, other different values can be used as needed.

[0113] Based on equations (3) and (4), each CSI report corresponding to CSI-ReportConfig or LTM-CSI-ReportConfig will have a unique priority value, and the CSI report corresponding to LTM-CSI-ReportConfig has a higher priority compared to the CSI report corresponding to CSI-ReportConfig . The conventional dropping rule can be applied based on the determined priority / priority value above.

[0114] It should be noted that the last term in equations (3) and (4) is different, which can ensure that the CSI report corresponding to LTM-CSI- ReportConfig has a higher priority compared to the CSI report corresponding to CSI-ReportConfig . However, equations (3) and (4) are only examples, the exact form of the equation for calculating the priority value of the CSI report for LTM and the CSI report for non-LTM can be designed otherwise based on the premise that the CSI report corresponding to LTM-CSI-ReportConfig has a higher priority compared to the CSI report corresponding to CSI-ReportConfig . For example, the last term in equation (3) can be replaced by, for example, , , etc.

[0115] In some implementations, the CSI report for LTM is configured by the first CSI report configuration (e.g., LTM-CSI- ReportConfig ) and the CSI report for non-LTM is configured by the second CSI report configuration (e.g., CSI- ReportConfigIn case the UE 104 is configured, for a CSI report (which can be a CSI report for LTM or a legacy CSI report), in addition to the reporting configuration ID of the CSI report configuration for the CSI report, the priority value of the CSI report can be determined based on the following: a type indication value indicating the reporting type of the CSI report, the reporting type can be one of the following: aperiodic, semi-persistent on PUSCH, semi-persistent on PUCCH, or periodic; a sum value of the maximum number of first CSI report configurations and the maximum number of second CSI report configurations; a serving cell index for the UE 104; a maximum number of serving cells; and a measurement indication value for the CSI report. Herein, the measurement indication value can include one of a first value, a second value, and a third value, the first value can indicate that the CSI report carries L1-RSRP or L1-SINR corresponding to the second CSI report configuration, the second value can indicate that the CSI report does not carry L1-RSRP or L1-SINR corresponding to the second CSI report configuration; and the third value can indicate that the CSI report is relative to the first CSI report configuration. The third value can be less than the first value and the second value.

[0116] In this case, the CSI report for non-LTM and the CSI report for LTM can be based on these parameters in the same way. For example, the priority value of the CSI report (which can be a CSI report for non-LTM or a CSI report for LTM) can be determined based on the following equation (5):

[0117] In the above equation (5), y The value of can indicate the reporting type of the CSI report, for example, y = 0 can indicate the aperiodic CSI report(s) to be carried on PUSCH, y = 1 can indicate the semi-persistent CSI report(s) to be carried on PUSCH, y = 2 can indicate the semi-persistent CSI report(s) to be carried on PUCCH, and y = 3 can indicate the periodic CSI report(s) to be carried on PUCCH. k The value of is the measurement indication value, for example, k = 0 can indicate the CSI report(s) carrying L1-RSRP or L1-SINR, k = 1 can indicate the CSI report(s) not carrying L1-RSRP or L1-SINR, k = -1 can indicate the CSI report corresponding to LTM-CSI-ReportConfig c is the serving cell index, and​​N cells is a value of a higher layer parameter maxNrofServingCells , which refers to the maximum number of serving cells configured for the UE. s (e.g., s 1 and s 2 is a value of a higher layer parameter CSI-ReportConfig of the CSI report. reportConfigID or LTM-CSI- ReportConfig of the CSI report. reportConfigID , which ranges from 0 to max{ maxNrofCSI-ReportConfigurations -1, maxNrofLTM-CSI-ReportConfigurations -1}, M s is a value of a higher layer parameter maxNrofCSI- ReportConfigurations and a value of a higher layer parameter maxNrofLTM-CSI-ReportConfigurations , i.e., a sum value of the maximum number of the first CSI report configuration and the maximum number of the second CSI report configuration. The values of these parameters are only examples, and other different values can be used as needed.

[0118] Based on equation (5), each CSI report corresponding to CSI-ReportConfig or LTM-CSI-ReportConfig will have a unique priority value, and the CSI report corresponding to LTM-CSI-ReportConfig has a higher priority compared to the CSI report corresponding to CSI- ReportConfig , because the LTM-CSI-ReportConfig for CSI report corresponding to k = -1. The conventional dropping rule can be applied based on the determined priority / priority value above.

[0119] Alternatively, to ensure that the CSI report for LTM has a positive priority value, equation (5) can be enhanced to equation (6) as follows:

[0120] Herein, if k has another negative value, then ( k +1) in equation (6) can be replaced by a sum of k and the absolute value of the other negative value to ensure that the priority value calculated by equation (6) is greater than 0.

[0121] In some implementations, the CSI report for LTM is configured by a first CSI report configuration (e.g., LTM-CSI- ReportConfig ) and the CSI report for non-LTM is configured by a second CSI report configuration (e.g., CSI-ReportConfig When configured, the priority values ​​for CSI reports used for LTM and the priority values ​​for CSI reports used for non-LTM can be determined using different parameters and in different ways.

[0122] For example, for CSI reports used for non-LTM (i.e., traditional CSI reports), in addition to the report configuration ID configured for the second CSI report used for non-LTM CSI reports, the priority value for CSI reports used for non-LTM can also be determined based on the following: a type indicator value indicating the report type of the CSI report, which can be one of the following: aperiodic, semi-persistent on PUSCH, semi-persistent on PUCCH, or periodic; a measurement indicator value indicating whether the corresponding CSI report carries L1-RSRP or L1-SINR; the maximum number of second CSI report configurations; the serving cell index for UE 104; and the maximum number of serving cells.

[0123] In addition, for CSI reports used for LTM, besides the report configuration ID configured for the first CSI report used for LTM, the priority value of the CSI report used for LTM can also be determined based on the following: a type indicator value indicating the report type of the corresponding CSI report, where the report type includes one of the following: non-periodic, semi-persistent on PUSCH, semi-persistent on PUCCH, or periodic; the maximum number of first CSI report configurations; the serving cell index for the UE; and the maximum number of serving cells.

[0124] For example, CSI reports for non-LTM (i.e., with) CSI-ReportConfig Priority value of the corresponding CSI report It can be determined based on the following equation (7):

[0125] In equation (7), High-level parameters maxNrofCSI-ReportConfiguration The value, that is, the maximum number of second CSI report configurations. s 1 This is for CSI reports used for non-LTM applications. CSI-ReportConfig of reportConfigID Equation (7) is the same as equation (1), and therefore will not be discussed in detail here.

[0126] In addition, the CSI report used for LTM (i.e., with LTM-CSI-ReportConfig Priority value of the corresponding CSI report It can be determined based on the following equation (8):

[0127] In Equation (8), y The value of y = 0 can indicate aperiodic CSI report(s) to be carried on PUSCH, y = 1 can indicate semi-persistent CSI report(s) to be carried on PUSCH, y = 2 can indicate semi-persistent CSI report(s) to be carried on PUCCH, y = 3 can indicate periodic CSI report(s) to be carried on PUCCH. c is a serving cell index, and N cells is a value of a higher layer parameter maxNrofServingCells , which refers to the maximum number of serving cells. s 2 is a value of LTM-CSI-ReportConfig for CSI reporting for LTM, reportConfigID , is a value of a higher layer parameter maxNrofLTM-CSI- ReportConfigurations , i.e., the maximum number of first CSI report configurations. The values of these parameters are only examples, and other different values can be used as needed.

[0128] In some implementations, in the case where the priority values for CSI reporting for LTM and the priority values for CSI reporting for non-LTM are determined independently as in Equations (7) and (8), when one or more CSI reports for LTM and non-LTM are to be reported in the same slot, and the resources for one CSI report for LTM and another CSI report for non-LTM overlap at least in one symbol, the UE 104 can first determine the LTM priority for each of the CSI reports for LTM based on the priority values for CSI reporting for LTM, and determine the non-LTM priority for each of the CSI reports for non-LTM based on the priority values for CSI reporting for non-LTM. Then, the UE 104 can determine the reporting priority between the CSI report for LTM with the highest LTM priority and the CSI report for non-LTM with the highest non-LTM priority based on a predetermined rule.

[0129] In some implementations, the predetermined rule can include that the CSI report for LTM has a higher reporting priority than the CSI report for non-LTM.

[0130] In some implementations, the predetermined rule can include assigning reporting priorities to the following items in a priority order from high to low: aperiodic CSI reporting for LTM, aperiodic CSI reporting for non-LTM, semi-persistent CSI reporting for LTM on PUSCH, semi-persistent CSI reporting for non-LTM on PUSCH, semi-persistent CSI reporting for LTM on PUCCH, semi-persistent CSI reporting for non-LTM on PUCCH, periodic CSI reporting for LTM, aperiodic CSI reporting for non-LTM, semi-persistent CSI reporting for non-LTM on PUSCH, semi-persistent CSI reporting for non-LTM on PUCCH, and periodic CSI reporting for non-LTM, i.e.: aperiodic CSI reporting for LTM > aperiodic legacy CSI reporting > semi-persistent CSI reporting for LTM on PUSCH > semi-persistent legacy CSI reporting on PUSCH > semi-persistent CSI reporting for LTM on PUCCH > semi-persistent legacy CSI reporting on PUCCH > periodic CSI reporting for LTM > periodic legacy CSI reporting.

[0131] In some implementations, the predetermined rule can include assigning reporting priorities to the following items in a priority order from high to low: aperiodic CSI reporting for LTM, semi-persistent CSI reporting for LTM on PUSCH, semi-persistent CSI reporting for LTM on PUCCH, periodic CSI reporting for LTM, aperiodic CSI reporting for non-LTM, semi-persistent CSI reporting for non-LTM on PUSCH, semi-persistent CSI reporting for non-LTM on PUCCH, and periodic CSI reporting for non-LTM, i.e.: aperiodic CSI reporting for LTM > semi-persistent CSI reporting for LTM on PUSCH > semi-persistent CSI reporting for LTM on PUCCH > periodic CSI reporting for LTM > aperiodic legacy CSI reporting > semi-persistent legacy CSI reporting on PUSCH > semi-persistent legacy CSI reporting on PUCCH > periodic legacy CSI reporting.

[0132] Figure 4 FIG. 4 illustrates another example of a signaling procedure of CSI reporting according to aspects of the present disclosure.

[0133] As Figure 4 As shown in FIG. 4, at step 402, the base station 102 determines a MAC CE for activating at least one semi-persistent CSI reporting configuration on PUCCH. Then at step 304, the base station 102 transmits the MAC CE to the UE 104. In some embodiments of the present disclosure, the base station 102 can be a source base station for LTM.

[0134] At step 406, UE 104 receives a MAC CE for activating at least one semi-persistent CSI reporting configuration on the PUCCH, and at step 408, activates at least one semi-persistent CSI reporting configuration on the PUCCH based on the MAC CE. In this document, the MAC CE may include an LTM field indicating that the MAC CE is used to activate either at least one semi-persistent CSI reporting configuration on the PUCCH for LTM or at least one semi-persistent CSI reporting configuration on the PUCCH for non-LTM.

[0135] Figure 5A and Figure 5B An example of activating / deactivating a MAC CE on a semi-persistent CSI report on PUCCH according to aspects of this disclosure is illustrated.

[0136] like Figure 5A As shown, the LTM field may include a bit indicating whether a predetermined field in the MAC CE is used for LTM or non-LTM. When this bit has a first value, each bit in the predetermined field indicates whether the corresponding semi-persistent CSI reporting configuration for LTM should be activated; when this bit has a second value different from the first value, each bit in the predetermined field indicates whether the corresponding semi-persistent CSI reporting configuration for non-LTM should be activated. The LTM field is included in the MAC CE by reusing reserved bits to indicate whether the MAC CE is used for SP CSI reporting activation for LTM on the PUCCH or traditional SP CSI reporting activation on the PUCCH. The MAC CE has a fixed size of 16 bits and contains several fields.

[0137] Specifically, the Serving Cell ID field indicates the identifier of the serving cell to which the MAC CE is applied, and the Serving Cell ID field is 5 bits long. The BWP ID field indicates the UL BWP to which the MAC CE is applied, and the BWP ID field is 2 bits long. The LTM field indicates the following S i The field is used to indicate csi-ReportConfigToAddModList or ltm-csi- ReportConfigToAddModList The semi-persistent CSI report configuration within the system shows the activation / deactivation status. The LTM field is set to 1 to indicate the activation / deactivation status of the S. i The field is used to indicate ltm-csi-ReportConfigToAddModList The semi-persistent CSI report configuration within the cell shows the activation / deactivation status, which configures all UE settings in the serving cell. LTM-CSI-ReportConfig The LTM field is set to 0 to indicate S i The field is used to indicate csi-ReportConfigToAddModList The semi-persistent CSI report configuration within the cell shows the activation / deactivation status, which configures all UE settings in the serving cell.CSI-ReportConfig i The field indicates the activation / deactivation status of the semi-persistent CSI reporting configuration within csi-ReportConfigToAddModList ltm-csi-ReportConfigToAddModList semiPersistentOnPUCCH CSI-ReportConfigId LTM-CSI- ReportConfigId CSI-ReportConfigId LTM-CSI-ReportConfigId and so on. If the number of CSI reporting configurations within the list of indicated BWP with Type set to semiPersistentOnPUCCH is less than i+1, the MAC entity shall ignore the S i i The field is set to 1 to indicate that the corresponding semi-persistent CSI reporting configuration should be activated. i The field is set to 0 to indicate that the corresponding semi-persistent CSI reporting configuration i should be deactivated. The R field refers to reserved bits and is set to 0.

[0138] In some implementations, the LTM field can include multiple bits, each of which indicates whether the corresponding semi-persistent CSI reporting configuration for LTM is activated.

[0139] As shown in Figure 5B , some LTM fields are introduced by reusing some reserved bits to indicate activated SP LTM CSI on PUCCH. The MAC has a fixed size of 16 bits, with several fields.

[0140] In particular, the serving cell ID field indicates the identity of the serving cell to which the MAC CE applies, and the length of the serving cell ID field is 5 bits. The BWP ID field indicates the UL BWP to which the MAC CE applies, and the length of the BWP ID field is 2 bits. i The field indicates the activation / deactivation status of the semi-persistent CSI reporting configuration within csi-ReportConfigToAddModList semiPersistentOnPUCCH CSI- ReportConfigId ​​​​​​​​​​S1 refers to the CSI reporting configuration, which includes the PUCCH resources in the indicated BWP for SP CSI reporting, and has a second minimum CSI-ReportConfigId And so on. If the indicated BWP has a type set to... semiPersistentOnPUCCH If the number of CSI report configurations in the list is less than i+1, the MAC entity should ignore S. i Field. S i The field is set to 1 to indicate that the corresponding semi-persistent CSI report configuration should be activated. i The field is set to 0 to indicate that the corresponding semi-persistent CSI report configuration i should be deactivated.

[0141] also, Figure 5B T in i Field Indicators ltm-csi-ReportConfigToAddModList The activation / deactivation status of the semi-persistent CSI reporting configuration within the system. T0 refers to the CSI reporting configuration that includes the PUCCH resource in the indicated BWP for SP CSI reporting, and whose type is set to... semiPersistentOnPUCCH The list contains the lowest LTM-CSI-ReportConfigId T1 refers to the CSI reporting configuration, which includes the PUCCH resources in the indicated BWP for SP CSI reporting, and has a second minimum LTM-CSI-ReportConfigId And so on. If the type in the indicated BWP is set to... semiPersistentOnPUCCH If the number of report configurations in the list is less than i+1, the MAC entity should ignore T. i Field. T i The field is set to 1 to indicate that the corresponding semi-persistent CSI reporting configuration should be activated. i The field is set to 0 to indicate that the corresponding semi-persistent CSI report configuration i should be deactivated. The R field refers to the reserved bits and is set to 0.
