[0004] Related technical description

[0005] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts or other similar types of services. These wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available wireless communication system resources.

[0006] Although wireless communication systems have made tremendous technical progress over the years, challenges still exist.

[0022] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for capability-based cell selection and cell reselection.

[0023] In some systems, the network provides system information that configures the UE for cell selection and cell reselection. In some aspects, the system information includes one or more parameters for determining whether a cell meets the cell selection / reselection criteria, and one or more parameters for determining whether to perform cell selection / reselection measurements. The system information may include one or more offsets, one or more thresholds, and / or other parameters for cell selection / reselection and for performing cell selection / reselection cell measurements. Typically, the system information is independent of UE capabilities. However, the UE and / or the network may prefer certain cell selection / reselection, depending on the capabilities of the UE and / or the network.

[0024] Various aspects of the present disclosure provide capability-based cell selection and reselection. In some aspects, first system information is provided for a UE that supports a first one or more capabilities, and second system information is provided for a UE that supports a second one or more capabilities. The second capability may include a lack of support for the first capability. For example, the first system information may include a first parameter for determining whether to perform cell reselection / reselection measurements and a first parameter for performing cell selection and cell reselection, and the second system information may include a second parameter for determining whether to perform cell reselection / reselection measurements and a second parameter for performing cell selection and cell reselection. Therefore, the UE may determine whether to use the first system information or the second system information for measurement and cell selection and reselection based on the capabilities of the UE and / or the capabilities of the cell or base station. Therefore, cell selection and reselection may be configured and / or performed in a more flexible and dynamic manner based on the capabilities of the network and / or the capabilities of the UE.

[0025] Introduction to wireless communication networks

[0026] The techniques and methods described herein can be used in various wireless communication networks. Although various aspects may be described herein using terms commonly associated with 3G, 4G and / or 5G wireless technologies, various aspects of the present disclosure may also be applicable to other communication systems and standards not explicitly mentioned herein.

[0027] Figure 1 An example of a wireless communication network 100 is depicted in which various aspects described herein may be implemented.

[0028] In general, the wireless communication network 100 includes various network entities (alternatively, network elements or network nodes). A network entity is typically a communication device and / or a communication function performed by a communication device (e.g., user equipment (UE), base station (BS), component of a BS, server, etc.). For example, various functions of a network and various devices associated with and interacting with the network may be considered network entities. In addition, the wireless communication network 100 includes ground aspects, such as ground-based network entities (e.g., BS 102), and non-ground aspects, such as satellites 140 and aircraft 145, which may include airborne network entities (e.g., one or more BSs) capable of communicating with other network elements (e.g., ground BSs) and user equipment.

[0029] In the depicted example, the wireless communication network 100 includes a BS 102, a UE 104, and one or more core networks (such as an evolved packet core (EPC) 160 and a 5G core (5GC) network 190), which interoperate to provide communication services over various communication links (including wired and wireless links).

[0030] Figure 1 Various example UEs 104 are depicted, which may more generally include: a cellular phone, a smart phone, a Session Initiation Protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player, a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, an Internet of Things (IoT) device, an Always-On (AON) device, an edge processing device, or other similar devices. UE 104 may also be more generally referred to as a mobile device, a wireless device, a wireless communication device, a station, a mobile station, a subscriber station, a mobile subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a remote device, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, and others.

[0031] BS 102 wirelessly communicates with (e.g., transmits signals to or receives signals from) UE 104 via communication link 120. Communication link 120 between BS 102 and UE 104 may include uplink (UL) (also referred to as a reverse link) transmissions from UE 104 to BS 102 and / or downlink (DL) (also referred to as a forward link) transmissions from BS 102 to UE 104. In various aspects, communication link 120 may employ multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity.

[0032] BS 102 may generally include: NodeB, enhanced NodeB (eNB), next generation enhanced NodeB (ng-eNB), next generation NodeB (gNB or gNodeB), access point, base transceiver station, radio base station, radio transceiver, transceiver function, transmission and reception point, and / or other. Each of BS 102 may provide communication coverage for a corresponding geographic coverage area 110, which may sometimes be referred to as a cell, and may overlap in some cases (e.g., a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of a macro cell). For example, a BS may provide communication coverage for a macro cell (covering a relatively large geographic area), a pico cell (covering a relatively small geographic area, such as a stadium), a femto cell (relatively small geographic area (e.g., a home)), and / or other types of cells.

[0033] Although BS102 is depicted as a single communication device in various aspects, BS102 can be implemented in various configurations. For example, one or more components of the base station may be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, to name a few examples. In another example, various aspects of the base station may be virtualized. More generally, a base station (e.g., BS102) may include components located at a single physical location or components located at various physical locations. In an example in which the base station includes components located at various physical locations, each component may perform a function so that each component together implements functionality similar to that of a base station located at a single physical location. In some aspects, a base station including components located at various physical locations may be referred to as a decomposed radio access network architecture, such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture. Figure 2 An example decomposed base station architecture is depicted and described.

[0034] Different BSs 102 within the wireless communication network 100 may also be configured to support different radio access technologies, such as 3G, 4G, and / or 5G. For example, a BS 102 configured for 4G LTE (collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC 160 via a first backhaul link 132 (e.g., an S1 interface). A BS 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) may interface with the 5GC 190 via a second backhaul link 184. The BSs 102 may communicate with each other directly or indirectly (e.g., via the EPC 160 or the 5GC 190) over a third backhaul link 134 (e.g., an X2 interface), which may be wired or wireless.

[0035] The wireless communication network 100 may subdivide the electromagnetic spectrum into various categories, frequency bands, channels, or other characteristics. In some aspects, the subdivision is provided based on wavelength and frequency, where frequency may also be referred to as a carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 410 MHz-7125 MHz, which is often (interchangeably) referred to as "below 6 GHz". Similarly, 3GPP currently defines frequency range 2 (FR2) as including 24,250 MHz-52,600 MHz, which is sometimes (interchangeably) referred to as "millimeter wave" ("mmW" or "mmWave"). A base station (e.g., a mmWave base station such as BS180) configured to communicate using mmWave / near mmWave radio bands may utilize beamforming (e.g., 182) with a UE (e.g., 104) to improve path loss and range.

[0036] The communication link 120 between the BS 102 and, for example, the UE 104 may be through one or more carriers, which may have different bandwidths (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, and / or other MHz) and may be aggregated in various aspects. The carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​than for UL).

[0037] Communications using higher frequency bands may have higher path loss and shorter range than communications at lower frequencies. Figure 1180) may utilize beamforming 182 with UE 104 to improve path loss and range. For example, BS 180 and UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. In some cases, BS 180 may send beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 may receive beamformed signals from BS 180 in one or more receive directions 182". UE 104 may also send beamformed signals to BS 180 in one or more transmit directions 182". BS 180 may also receive beamformed signals from UE 104 in one or more receive directions 182'. BS 180 and UE 104 may then perform beam training to determine the best receive and transmit directions for each of BS 180 and UE 104. It is noteworthy that the transmit direction and receive direction of BS 180 may be the same or may not be the same. Similarly, the transmit direction and receive direction of UE 104 may or may not be the same.

[0038] Wireless communication network 100 also includes Wi-Fi AP 150 that communicates with Wi-Fi station (STA) 152 via communication link 154 in, for example, the 2.4 GHz and / or 5 GHz unlicensed spectrum.

[0039] Certain UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), and / or a physical sidelink feedback channel (PSFCH).

[0040] The EPC 160 may include various functional components, including: a mobility management entity (MME) 162, other MMEs 164, a serving gateway 166, a multimedia broadcast multicast service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and / or a packet data network (PDN) gateway 172, such as in the depicted example. The MME 162 may communicate with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. Generally, the MME 162 provides bearer and connection management.

[0041] Typically, user Internet Protocol (IP) packets are delivered through the Serving Gateway 166, which itself is connected to the PDN Gateway 172. The PDN Gateway 172 provides UE IP address allocation and other functions. The PDN Gateway 172 and the BM-SC 170 are connected to IP services 176, which may include, for example, the Internet, an intranet, an IP Multimedia Subsystem (IMS), a Packet Switched (PS) streaming media service, and / or other IP services.

[0042] The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS delivery, may be used to authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and / or may be used to schedule MBMS delivery. The MBMS Gateway 168 may be used to distribute MBMS services to BSs 102 belonging to a multicast broadcast single frequency network (MBSFN) area broadcasting a specific service, and / or may be responsible for session management (start / stop) and for collecting eMBMS related charging information.

[0043] 5GC 190 may include various functional components, including: access and mobility management function (AMF) 192, other AMF 193, session management function (SMF) 194 and user plane function (UPF) 195. AMF 192 may communicate with unified data management (UDM) 196.

[0044] AMF 192 is a control node that handles signaling between UE 104 and 5GC 190. AMF 192 provides, for example, Quality of Service (QoS) flow and session management.

[0045] Internet Protocol (IP) packets are delivered through UPF 195, which is connected to IP Services 197 and provides UE IP address allocation and other functions for 5GC 190. IP Services 197 may include, for example, the Internet, Intranet, IMS, PS streaming services, and / or other IP services.

[0046] In various aspects, a network entity or network node may be implemented as a converged base station, a decomposed base station, a component of a base station, an integrated access and backhaul (IAB) node, a relay node, a sidelink node, to name a few examples.

[0047] Figure 2An example disaggregated base station 200 architecture is depicted. The disaggregated base station 200 architecture may include one or more central units (CUs) 210 that may communicate directly with a core network 220 via a backhaul link, or indirectly with the core network 220 through one or more disaggregated base station units, such as a near real-time (near-RT) RAN intelligent controller (RIC) 225 via an E2 link, or a non-real-time (non-RT) RIC 215 associated with a service management and orchestration (SMO) framework 205, or both. The CU 210 may communicate with one or more distributed units (DUs) 230 via respective midhaul links, such as an F1 interface. The DU 230 may communicate with one or more radio units (RUs) 240 via respective fronthaul links. The RU 240 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 240.

[0048] Each of the units (e.g., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO framework 205) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interface of the unit may be configured to communicate with one or more of the other units via a transmission medium. For example, the unit may include a wired interface configured to receive or send signals to one or more of the other units on a wired transmission medium. Additionally or alternatively, the unit may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as a radio frequency (RF) transceiver) configured to receive or send signals, or both, to one or more of the other units via a wireless transmission medium.

[0049] In some aspects, the CU 210 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 210. The CU 210 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP)), control plane functionality (e.g., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, the CU 210 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 210 may be implemented to communicate with the DU 230 for network control and signaling.

[0050] The DU 230 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 240. In some aspects, the DU 230 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) at least in part according to a functional split such as those defined by the Third Generation Partnership Project (3GPP). In some aspects, the DU 230 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 230 or with control functions hosted by the CU 210.

[0051] The lower layer functions may be implemented by one or more RUs 240. In some deployments, the RU 240 controlled by the DU 230 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on functional splitting (such as lower layer functional splitting). In such an architecture, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration may enable the implementation of the DU 230 and the CU 210 in a cloud-based RAN architecture (such as a vRAN architecture).

[0052] The SMO framework 205 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 205 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 205 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 290) to perform network element lifecycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some specific implementations, the SMO framework 205 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 211) via the O1 interface. Additionally, in some specific implementations, the SMO framework 205 may communicate directly with one or more RUs 240 via the O1 interface. The SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of the SMO framework 205 .

[0053] The non-RT RIC 215 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 225. The non-RT RIC 215 may be coupled to or in communication with the near-RT RIC 225 (such as via an A1 interface). The near-RT RIC 225 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 210, one or more DUs 230, or both, and the O-eNB with the near-RT RIC 225.

[0054] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 225, the non-RT RIC 215 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 225 and may be received from a non-network data source or from a network function at the SMO framework 205 or the non-RT RIC 215. In some examples, the non-RT RIC 215 or the near-RT RIC 225 may be configured to adjust RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 205 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0055] Figure 3 Aspects of an example BS 102 and UE 104 are depicted.

[0056] In general, BS 102 includes various processors (e.g., 320, 330, 338, and 340), antennas 334a-334t (collectively 334), transceivers 332a-332t (collectively 332) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., data source 312) and wireless reception of data (e.g., data sink 339). For example, BS 102 can transmit and receive data between BS 102 and UE 104. BS 102 includes a controller / processor 340 that can be configured to implement various functions described herein related to wireless communication.

[0057] In general, the UE 104 includes various processors (e.g., 358, 364, 366, and 380), antennas 352a-352r (collectively 352), transceivers 354a-354r (collectively 354) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., retrieved from a data source 362) and wireless reception of data (e.g., provided to a data sink 360). The UE 104 includes a controller / processor 380 that can be configured to implement various functions described herein related to wireless communications.

[0058] Regarding example downlink transmissions, BS 102 includes a transmit processor 320 that can receive data from a data source 312 and control information from a controller / processor 340. The control information can be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical HARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), and / or others. In some examples, the data can be for a physical downlink shared channel (PDSCH).

[0059] The transmit processor 320 may process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. The transmit processor 320 may also generate reference symbols, such as for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH demodulation reference signal (DMRS), and a channel state information reference signal (CSI-RS).

[0060] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, and / or reference symbols, where applicable, and may provide an output symbol stream to a modulator (MOD) in transceivers 332a to 332t. Each modulator in transceivers 332a-332t may process a corresponding output symbol stream to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators in transceivers 332a to 332t may be transmitted via antennas 334a to 334t, respectively.

[0061] To receive downlink transmissions, UE 104 includes antennas 352a-352r that can receive downlink signals from BS 102 and can provide received signals to demodulators (DEMODs) in transceivers 354a-354r, respectively. Each demodulator in transceivers 354a-354r can condition (e.g., filter, amplify, downconvert, and digitize) a corresponding received signal to obtain input samples. Each demodulator can further process the input samples to obtain received symbols.

[0062] A MIMO detector 356 may obtain received symbols from all demodulators in transceivers 354a-354r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 358 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 104 to a data sink 360, and provide decoded control information to a controller / processor 380.

[0063] With respect to example uplink transmissions, the UE 104 also includes a transmit processor 364 that may receive and process data from a data source 362 (e.g., for a PUSCH) and control information from a controller / processor 380 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 364 may also generate reference symbols for reference signals (e.g., a sounding reference signal (SRS)). The symbols from the transmit processor 364 may be pre-decoded by a TX MIMO processor 366, if applicable, further processed by a modulator in the transceivers 354a-354r (e.g., for SC-FDM), and transmitted to the BS 102.

[0064] At BS 102, uplink signals from UE 104 may be received by antennas 334 a-334 t, processed by demodulators in transceivers 332 a-332 t, detected by MIMO detector 336 if applicable, and further processed by receive processor 338 to obtain decoded data and control information transmitted by UE 104. Receive processor 338 may provide decoded data to data sink 339 and decoded control information to controller / processor 340.

[0065] Memories 342 and 382 may store data and program codes for BS 102 and UE 104, respectively.

[0066] Scheduler 344 may schedule UEs for data transmission on the downlink and / or uplink.

[0067] In various aspects, the BS 102 may be described as sending and receiving various types of data associated with the methods described herein. In these contexts, "sending" may refer to various mechanisms for outputting data, such as outputting data from a data source 312, a scheduler 344, a memory 342, a transmit processor 320, a controller / processor 340, a TX MIMO processor 330, a transceiver 332a-332t, an antenna 334a-334t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as obtaining data from an antenna 334a-334t, a transceiver 332a-332t, a RX MIMO detector 336, a controller / processor 340, a receive processor 338, a scheduler 344, a memory 342, and / or other aspects described herein.

[0068] In various aspects, the UE 104 may also be described as sending and receiving various types of data associated with the methods described herein. In these contexts, "sending" may refer to various mechanisms for outputting data, such as outputting data from a data source 362, a memory 382, ​​a transmit processor 364, a controller / processor 380, a TX MIMO processor 366, a transceiver 354a-354t, an antenna 352a-352t, and / or other aspects described herein.

[0069] In some aspects, the processor may be configured to perform various operations (such as those associated with the methods described herein) and send (output) data to or receive (obtain) data from another interface configured to send or receive data, respectively.

[0070] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes a method for use in a wireless communication network such as Figure 1 Various aspects of the data structure of the wireless communication network 100).

[0071] Specifically, Figure 4A is a diagram 400 illustrating an example of a first subframe within a 5G (e.g., 5G NR) frame structure, Figure 4B is a diagram 430 illustrating an example of a DL channel within a 5G subframe, Figure 4C is a diagram 450 illustrating an example of a second subframe within a 5G frame structure, and Figure 4D FIG480 is a diagram illustrating an example of UL channels within a 5G subframe.

[0072] Wireless communication systems may utilize orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) on both the uplink and downlink. Such systems may also support half-duplex operation using time division duplex (TDD). OFDM and single carrier frequency division multiplexing (SC-FDM) can be used to maximize the system bandwidth (e.g., Figure 4B and Figure 4D The modulation symbols may be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0073] The wireless communication frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to either DL or UL. The wireless communication frame structure may also be time division duplex (TDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to both DL and UL.

[0074] exist Figure 4A and Figure 4C In the wireless communication frame structure, TDD is used, where D is DL, U is UL, and X is used flexibly between DL / UL. The UE can be configured with a time slot format (dynamically configured by DL control information (DCI) or semi-statically / statically configured by radio resource control (RRC) signaling) through the received time slot format indicator (SFI). In the depicted example, the 10ms frame is divided into 10 equally sized 1ms subframes. Each subframe may include one or more time slots. In some examples, each time slot may include 7 or 14 symbols, depending on the time slot format. The subframe may also include micro-time slots, which typically have fewer symbols than the entire time slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0075] In certain aspects, the number of slots within a subframe is based on the slot configuration and parameter set. For example, for slot configuration 0, different parameter sets (μ) 0 to 5 allow for 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, different parameter sets 0 to 2 allow for 2, 4, and 8 slots per subframe, respectively. Thus, for slot configuration 0 and parameter set μ, there are 14 symbols / slot and 2μ slots / subframe. The subcarrier spacing and symbol length / duration are a function of the parameter set. The subcarrier spacing may be equal to 2 μ × 15kHz, where μ is parameter set 0 to 5. Thus, parameter set μ=0 has a subcarrier spacing of 15kHz, and parameter set μ=5 has a subcarrier spacing of 480kHz. The symbol length / duration is inversely related to the subcarrier spacing. Figure 4A , Figure 4B , Figure 4C and Figure 4D An example is provided for slot configuration 0 with 14 symbols per slot and parameter set μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

[0076] like Figure 4A , Figure 4B , Figure 4C and Figure 4DAs depicted in , a resource grid may be used to represent a frame structure. Each time slot includes a resource block (RB) (also referred to as a physical RB (PRB)) extending, for example, over 12 consecutive subcarriers. The resource grid is divided into a plurality of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0077] like Figure 4A As illustrated, some of the REs carry data for UEs (eg, Figure 1 and Figure 3 The RS may include a demodulation RS (DMRS) and / or a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0078] Figure 4B Examples of various DL channels within a subframe of a frame are illustrated.The Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs), each CCE comprising, for example, nine RE Groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0079] The primary synchronization signal (PSS) may be in symbol 2 of a particular subframe of a frame. The PSS is transmitted by a UE (e.g., Figure 1 and Figure 3 104) is used to determine subframe / symbol timing and physical layer identification.

[0080] The Secondary Synchronization Signal (SSS) may be within symbol 4 of a particular subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and radio frame timing.

[0081] Based on the physical layer identifier and the physical layer cell identifier group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DMRS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block. The MIB provides the number of RBs in the system bandwidth and the system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information (such as system information blocks (SIBs)) that is not sent via the PBCH, and / or paging messages.

[0082] like Figure 4CAs illustrated, some of the REs carry DMRS for channel estimation at the base station (indicated as R for one particular configuration, but other DMRS configurations are possible). The UE may send a DMRS for the PUCCH and a DMRS for the PUSCH. The PUSCH DMRS may be sent, for example, in the first one or two symbols of the PUSCH. The PUCCH DMRS may be sent in different configurations depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used. The UE 104 may send a sounding reference signal (SRS). The SRS may be sent, for example, in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the teeth of the comb. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0083] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), and HARQ ACK / NACK feedback. The PUSCH carries data and may be used to carry, among other things, buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0084] A UE searching for a cell to camp on performs cell selection to search for and select a cell to camp on. A UE already camping on a cell performs cell reselection to search for and select a new cell to camp on.

[0085] A UE in an RRC_IDLE state or an RRC_INACTIVE state performs cell selection and reselection after selecting a public land mobile network (PLMN) or a standalone non-public network (SNPN).

[0086] With cell selection, the UE searches for a suitable cell of the selected PLMN or selected SNPN, selects the cell to provide available services, and monitors its control channels. This process is defined as "camping on a cell". A suitable cell may be a cell that meets the suitable cell criteria of a cell that the UE can camp on. An example of a suitable cell criteria is defined in 3GPP TS 36.304v17.1.0, clause 4.5.

[0087] After selecting a cell, the UE may perform a non-access stratum (NAS) registration procedure in the tracking area of ​​the selected cell to register the UE's presence in the cell.

[0088] While camped on the cell, if the UE finds a more suitable cell according to the cell reselection criteria, the UE reselects to the cell and camps on it. If the new cell does not belong to at least one tracking area to which the UE is registered, the UE may perform another location registration.

[0089] When the UE resides on a cell in the RRC_IDLE or RRC_ANACTIVE state, the UE can receive system information from the PLMN or SNPN, and the UE can establish an RRC connection or resume a suspended RRC connection by initially accessing the network on the control channel of the cell where it resides. If the network needs to transmit a message or transfer data to the registered UE, the network can transmit a "paging" message to the UE on the control channels of all cells in the corresponding area set. The UE will then receive the paging message and can respond. The UE can then transition to the RRC_CONNECTED mode.

[0090] One example of a cell selection and reselection procedure is defined in 3GPP TS 36.304 v17.1.0, clause 5.2.

[0091] For initial cell selection (without prior configuration of which radio frequency (RF) channels are NR frequencies), the UE scans all RF channels in the NR band to find a suitable cell based on its capabilities. On each frequency, the UE may search only for the strongest cell, except for operation with shared spectrum channel access, in which the UE may search for the next strongest cell.

[0092] The stored information for several RATs may be used to speed up cell selection.For example, the UE may store information on frequency and cell parameters from previously received measurement control information elements or from previously detected cells.

[0093] Cell reservation or access restrictions may be imposed on one or more cells.The network may control the RAT in which cell selection should be performed, for example by indicating the RAT associated with the selected PLMN and by maintaining a list of forbidden registration areas and a list of equivalent PLMNs.

[0094] Once a suitable cell is found, the UE selects that cell. If no suitable cell is found, a different initial cell selection process may be started.

[0095] The cell selection criteria are met when the following conditions are met:

[0096] Srxlevl>0 and

[0097] Squal>0, where

[0098] Srxlev=Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation–

[0099] Qoffset temp ,and

[0100] Squal=Qqualmeas–(Qualmin+Qualminoffset)–Qoffset temp

[0101] Srxlev is the cell selection signal reception (RX) level value, which can be expressed in decibels (dB). Qrxlevmeas is the measured cell RX level value, such as reference signal received power (RSRP). Qrxlevmin is the minimum required RX level in the cell, which can be expressed in dBm. Q can be received in system information. rxlevmin The parameter (e.g., in the q-RxLevMinSUL IE if the UE supports Supplementary Uplink (SUL), or in the q-RxLevMin IE). Qrxlevminoffset is the offset of Qrxlev taken into account in the Srxlev evaluation as a result of the periodic search for higher priority PLMNs when camped normally. rxlevmin Pcompensation is an additional compensation offset. Pcompensation may be used for FR1 if the UE supports it. The Pcompensation parameter may be received in system information (e.g., in the additionalPmax parameter in the NR-NS-PmaxList IE). Pcompensation may be:

[0102] max(P EMAX1 –P PowerClass ,0)–(min(P EMAX2 ,P PowerClass )–min(P EMAX1 ,P PowerClass ))(dB),

[0103] else max(P EMAX1 –P PowerClass ,0)(dB), where Pcompensation is set to zero for FR2 and Pcompensation is set to zero for an integrated access and backhaul (IAB) mobile terminal (MT). EMAX1 and P EMAX2 P is the maximum signal transmit (TX) power level that a UE can use when transmitting on the uplink in a cell. P may be received in system information. EMAX1 and PEMAX2 (For example, in the p-Max parameter in the NR-NS-PmaxList IE). PowerClass is the maximum RF output power of the UE according to the UE power class (dBm).

[0104] Squal is the cell selection quality value, which may be in dB. Qqualmeas is a measured cell quality value, such as reference signal received quality (RSRQ). Qualmin is the minimum required quality level in the cell, which may be in dB. The Qualmin parameter may be received in system information. Qualminoffset is the offset to Q that is considered in the Squal evaluation as a result of periodic searches for higher priority PLMNs when camped normally. qualmin offset.

[0105] Qoffset temp Qoffset is an offset temporarily applied to a cell, which can be expressed in dB. temp The parameters are signaled to the UE.

[0106] Q rxlevminoffset and Q qualminoffset May only be applicable to the case where cells are evaluated for cell selection as a result of a periodic search for a higher priority PLMN when normally camped in a VPLMN.During this periodic search for a higher priority PLMN, the UE may check the criteria of a cell using parameter values ​​stored from different cells of the higher priority PLMN.

[0107] When camped on a cell, the UE periodically searches for a better cell according to the cell reselection criteria. If a better cell is found, it is selected. When evaluating Srxlev and Squal of non-serving cells for reselection evaluation purposes, the UE uses the parameters provided by the serving cell, and for the final check of the cell selection criteria, the UE uses the parameters provided by the target cell for cell reselection. The priority between different frequencies or RATs for cell reselection may be provided to the UE via system information or dedicated signaling.

[0108] In some cases, when the serving cell meets one or more thresholds configured by system information, the UE performs inter-frequency measurements. For example, the measurement thresholds include: IntraSearchP , which specifies the Srxlev threshold (in dB) for intra-frequency measurements; S IntraSearchQ , which specifies the Squal threshold (in dB) for intra-frequency measurements; S nonIntraSearchP , which specifies the Srxlev threshold (in dB) for NR inter-frequency and inter-RAT measurements; S nonIntraSearchQ, which specifies the Squal threshold (in dB) for NR inter-frequency and inter-RAT measurements; S SearchDeltaP , which specifies the threshold (in dB) of the measured Srxlev change for relaxation; S SearchDeltaP-Stationary , which specifies the threshold (in dB) used to evaluate the change in the settling standard for relaxed measurements; S SearchThresholdP , which specifies the Srxlev threshold (in dB) for the relaxed measurement; S SearchThresholdP2 , which specifies the Srxlev threshold (in dB) used to evaluate the non-cell-edge criterion for relaxed measurements; S SearchThresholdQ , which specifies the Squal threshold (in dB) for the relaxed measurement; and S SearchThresholdQ2 , which specifies the Squal threshold (in dB) used to evaluate the not-at-cell-edge criterion for measurements used for relaxation.

[0109] To transition the UE to RRC_IDLE or RRC_INACTIVE, the UE attempts to camp on a suitable cell. When the UE returns to the RRC_IDLE state after moving from the camped on any cell state to the RRC_CONNECTED state, the UE attempts to camp on an acceptable cell. An example of an acceptable cell criterion is defined in 3GPP TS 36.304v17.1.0, clause 4.5. The RRC release message from the network may indicate a redirectedCarrierInfo parameter with acceptable cell information. If the UE cannot find an acceptable cell, the UE is allowed to camp on any acceptable cell of the indicated RAT.

[0110] The RRC release message may further include a cellReselectionPriorities parameter. If the RRC release message does not include the cellReselectionPriorities parameter or the t320 timer expires, the UE applies the cell reselection priority information broadcast in the system information.

[0111] Figure 55 is an example process flow 500 for cell selection and cell reselection. As shown in process flow 500, at 502, the UE may measure a serving cell (e.g., perform measurements on a signal received from the serving cell). At 506, if the serving cell measurement is not low (e.g., at or above a threshold), the UE returns to 502 to measure the serving cell. At 506, if the serving cell measurement is low (e.g., below a threshold), the UE measures a new lower priority inter-frequency cell and / or measures a new intra-frequency cell and / or a new equal priority inter-frequency cell at 510. At 514 or 516, if the new measurement is not high (e.g., below a threshold), the UE returns to 502 to measure the serving cell. At 514, if the new lower priority inter-frequency cell is high (e.g., at or above a threshold), at 518, the UE adds the cell to the list of low priority frequency cells. At 516 , if the new intra-frequency cell or equal priority inter-frequency cell is high (eg, at or above a threshold), then at 520 , the UE adds the cell to a list of low priority frequency cells.

[0112] At 504, the UE may measure one or more high priority inter-frequency cells. At 508, if the high priority cell is not high (e.g., below a threshold), the UE returns to 504 to measure a higher priority inter-frequency cell. At 508, if the high priority cell is not high (e.g., at or above a threshold), at 522, the UE adds the cell to a list of higher priority high priority frequency cells.

[0113] At 524, the UE selects one of the cells in the cell list (e.g., added at 518, 520, 522). At 526, the UE sorts the cell list by rank. At 528, the UE filters the list of prohibited / reserved cells (e.g., prohibited / reserved indicated by system information). At 530, if no range to the best cell is configured, then at 532, the UE (re)selects the cell with the highest rank in the list. If a range to the best cell is configured, then at 534, the UE (re)selects the highest rank cell with the highest number of beams above a threshold from the list within the range.

[0114] The base station may preferably serve those UEs with a first UE capability on a first cell, and potentially serve those UEs without such capability on a different cell. For example, a base station cell supporting BS-side full-duplex (FD) operation may preferably serve UEs that can report the "worst" beam or support CLI measurements, each of which are UE capabilities. FD operation includes support for simultaneous uplink and downlink transmissions on a carrier.

[0115] Similarly, a UE with the first UE capability may be preferably served by a cell supporting a serving UE with the first UE capability. For example, a UE supporting UE-side FD operation capability may be preferably served on a cell that schedules the UE in consideration of the capability to achieve higher UE throughput.

[0116] In addition, the base station cell to perform network energy saving may preferably serve UEs that can support dynamic activation / deactivation of type 2 configuration grant PUSCH, so as to dynamically adapt UL UE transmission in energy saving mode on the base station cell. Type 2 configuration grant can be an RRC configuration semi-persistent UL grant, which can be activated by downlink control information (DCI) signaling.

[0117] A base station cell to perform network energy saving may preferably serve UEs that can dynamically report traffic forecasts to the base station cell to reduce blind monitoring of the base station cell on preconfigured UL UE transmission opportunities such as CG-PUSCH or scheduling requests.

[0118] The base station may implement energy saving on a cell that may use a different synchronization signal block (SSB) or common channel configuration, which may have an impact on some legacy UEs. Such UEs affected by different SSB or common channel configurations should not camp on the cell. Energy-saving cells may be included in the system information block (SIB) of normal cells as (legacy) neighbor cells. Otherwise, legacy UEs will search for energy-saving cells and waste power. On the other hand, UEs with enhanced capabilities may be able to find energy-saving cells.

[0119] As described above, the UE selects / reselects a cell based on the cell selection / reselection parameters in the system information, however, these parameters are independent of the UE capabilities. Therefore, the UE may camp on a cell, and after performing initial access and reporting capabilities, the UE may have to be handed over to a different cell. This results in additional latency and signaling overhead.

[0120] In addition, using RedirectedCarrierInfo and / or cellReselectionPriorities in the RRC Release message, the UE connects to the network and reports the UE capabilities. After transitioning back to the idle or inactive state, the network provides the UE with dedicated reselection parameters, which may be based on the capabilities reported by the UE. However, these reselection parameters are unicast only and require the UE to first connect to the network and report the UE capabilities.

[0121] Furthermore, using the capability related barring information in the SIB, the IAB-MT only (re)selects cells that broadcast in SIB1 that they support IAB. In addition, the "RedCap broadcast information" may indicate whether the cell allows or bars access to RedCap UEs with 1RX and 2RX branches. If barred, the cell is not a candidate for selection / reselection.

[0122] Therefore, capability-based cell selection and reselection may be provided to address the issues discussed above. For example, in the case of capability-based cell selection and reselection, a base station that preferably serves UEs supporting a particular capability on a particular cell may configure such UEs to have looser cell (re)selection criteria for that cell (e.g., via system information having cell selection parameters, priorities, and / or thresholds) and / or to have stricter cell (re)selection criteria for selecting a different cell. Similarly, a UE that is preferably served by a cell supporting a particular capability may use or be configured by the network to use system information having looser cell (re)selection criteria for cells supporting that capability and / or having stricter cell (re)selection criteria for cells that do not support that capability.

[0123] Aspects related to capability-based cell selection and cell reselection

[0124] Figure 6 A process flow 600 is depicted for communication in a network between a network entity 602, a first UE 604, and a second UE 606. In some aspects, the network entity 602 may be a Figure 1 and Figure 3 BS102 as depicted and described or with respect to Figure 2 An example of a decomposed base station is depicted and described. Similarly, the first UE 604 and the second UE 606 may be related to Figure 1 and Figure 3 1 and 10. However, in other aspects, the first UE 604 and the second UE 606 can be another type of wireless communication device, and the network entity 602 can be another type of network entity or network node, such as the network entity or network node described herein. In some examples, the first UE 604 and / or the second UE 606 are in RRC idle mode or RRC inactive mode.

[0125] At 608, the network entity 602 provides system information to the first UE 604 and the second UE 606. In some examples, the network entity 602 broadcasts one or more SIBs including the system information to the first UE 604 and the second UE 606. For example, the system information may be broadcast in any one or more SIB1, SIB2, SIB3, SIB4, SIB5, or a new SIB. In some examples, the system information is broadcast by a serving cell, a neighboring cell, or both. In some examples, the system information is group common system information for a group of UEs. In some examples, the system information is provided to a single UE in dedicated signaling.

[0126] The system information includes first system information associated with the first one or more capabilities and second system information associated with the second one or more capabilities.

[0127] The first system information may include a first parameter for determining whether to perform cell selection and cell reselection measurement and a first parameter for performing cell selection and cell reselection. The second system information may include a second parameter for determining whether to perform cell selection and cell reselection measurement and a second parameter for performing cell selection and cell reselection.

[0128] In some examples, the system information includes: a first threshold value for determining cell measurements for performing cell selection and / or cell reselection measurements for a cell or a cell frequency, the first threshold value being associated with a first one or more capabilities; and a second threshold value for determining cell measurements for performing cell selection and / or cell reselection measurements for a cell or a cell frequency, the second threshold value being associated with a second one or more capabilities.

[0129] In some examples, the system information includes: a first threshold for determining cell measurements for performing cell selection and / or cell reselection measurements for a cell or cell frequency, the first threshold being associated with a first one or more capabilities; and an offset of the first threshold being associated with a second one or more capabilities.

[0130] In some examples, the system information includes: a first threshold for determining cell measurements for performing cell selection and / or cell reselection measurements for a cell or frequency, the first threshold being associated with a first one or more capabilities; and a scaling factor for the first threshold, the scaling factor being associated with a second one or more capabilities.

[0131] In some examples, the system information includes: a first threshold value for cell measurement for (re)selecting a cell, the first threshold value being associated with a first one or more capabilities; and a second threshold value for cell measurement for (re)selecting a cell, the second threshold value being associated with a second one or more capabilities.

[0132] In some examples, the system information includes: a first threshold for cell measurement for (re)selecting a cell, the first threshold associated with a first one or more capabilities; and an offset of the first threshold, the offset associated with a second one or more capabilities.

[0133] In some examples, the system information includes: a first threshold for cell measurement for (re)selecting a cell, the first threshold being associated with a first one or more capabilities; and a scaling factor of the first threshold being associated with a second one or more capabilities.

[0134] In some examples, the system information includes: first one or more priorities for (re)selecting one or more cells, the first one or more priorities being associated with first one or more capabilities; and second one or more priorities for (re)selecting one or more cells, the second one or more priorities being associated with second one or more capabilities.

[0135] In some examples, the system information includes: a first time period for measuring and / or (re)selecting conditional validity of one or more cells or cell frequencies, the first time period being associated with a first one or more capabilities; and a second time period for measuring and / or (re)selecting conditional validity of one or more cells or cell frequencies, the second time period being associated with a second one or more capabilities.

[0136] In some examples, the system information includes both capability-based system information and capability-independent system information used for cell measurement and / or cell selection and reselection.

[0137] The network energy saving state of a cell may be exchanged between network entities. For example, the network energy saving state information of a cell may be exchanged between gNB, CU, DU and / or operation, administration and maintenance (OAM) processes and functions. In some examples, a cell may be in one of several network energy saving states. In the "normal active" network energy saving state, any UE may access the cell. In the "power saving" network energy saving state, the cell may be less preferred for UEs that require high performance. In the "deep power saving" network energy saving state, where the cell may send reduced SSBs, normal UEs should not camp on the cell. In the "inactive" network energy saving state, the cell may be triggered by a wake-up signal from a UE to camp on the cell. Legacy UEs in deep power saving or inactive cells may be handed over to a new neighbor list (e.g., in SIB3 or SIB4). In some examples, the network energy saving state of the cell may be provided to the UE in system information, and the UE may further use the network energy saving state information of the cell in cell selection and reselection based on UE capabilities.

[0138] In some examples, the first system information includes first cell barring information associated with the first one or more capabilities, and the second system information includes second cell barring information associated with the second one or more capabilities. The first cell barring information may indicate one or more cells as unavailable for cell selection and cell reselection, and the second cell barring information may indicate one or more cells as available for cell selection and cell reselection.

[0139] In some examples, the first system information includes cell whitelist information of one or more cells, the cell whitelist information is associated with the first one or more capabilities, and the second system information includes blacklist information of one or more cells, the blacklist information is associated with the second one or more capabilities. The whitelisted cells indicate cells for performing measurements for cell selection and reselection. The blacklisted cells indicate cells for which measurements for cell selection and reselection are to be skipped.

[0140] Therefore, the UE may use the first system information or the second system based on the capabilities of the UE, cell or network entity. Figure 6 As shown, at 610, the first UE 604 determines a first one or more capabilities.

[0141] The first one or more capabilities may include capabilities of the UE, capabilities of the network entity, and / or capabilities of one or more cells. The first one or more capabilities may include capabilities associated with a first feature set, and the second one or more capabilities may include capabilities associated with a second feature set. In some examples, the second one or more capabilities may lack support for the first one or more capabilities.

[0142] These capabilities may include FD capabilities of the network entity and / or UE. These capabilities may include the ability of the UE to report the "worst" beam. These capabilities may include the ability of the UE to perform DLI measurements. The ability of the network entity and / or one or more cells to schedule the UE takes into account the UE capabilities for FD operations. The capability may include the ability of the UE to support dynamic activation / deactivation of type 2 configuration authorization. The capability may include the ability of the UE to dynamically report traffic forecasts to the network entity to support network energy saving. The capability may include the enhanced ability of the UE to support non-legacy SSB or common channel configurations for network energy saving. The capability may include the reduction capability of RedCap UE. The capability may include the IAB MT capability of the UE.

[0143] At 614, based on determining the first one or more capabilities, the first UE 604 determines first parameters, thresholds, and / or priorities for performing cell selection / reselection measurements and / or for performing cell selection and / or reselection using the first system information.

[0144] In some examples, the first parameter, threshold, and / or priority determined at 614 based on the first system information includes one or more of the following: a first Srxlev threshold, a first Squal threshold, a first Qrxlevmin; a first Qrxlevminoffset; a first Pcompensation; a first Qualmin; a first Qualminoffset; a first Qoffset temp ; First S IntraSearchP ; First S IntraSearchQ ; First S nonIntraSearchP ; First S nonIntraSearchQ ; First S SearchDeltaP ; First S SearchDeltaP-Stationary ; First S SearchThresholdP ; First S SearchThresholdP2 ; S SearchThresholdQ ; and / or first S SearchThresholdQ2 .

[0145] On the other hand, at 612, the second UE 606 determines a second one or more capabilities. The second one or more capabilities may include any set of capabilities that are different from the first one or more capabilities. In some examples, the second one or more capabilities include a lack of support for one or more of the first one or more capabilities.

[0146] At 616 , based on determining the second one or more capabilities, the second UE 606 determines second parameters, thresholds, and / or priorities for performing cell selection / reselection measurements and / or for performing cell selection and / or reselection using the second system information.

[0147] In some examples, the second parameter, threshold, and / or priority determined at 616 based on the second system information includes one or more of the following: a second Srxlev threshold, a second Squal threshold, a second Qrxlevmin; a second Qrxlevminoffset; a second Pcompensation; a second Qualmin; a second Qualminoffset; a second Qoffset temp ; Second S IntraSearchP ; Second S IntraSearchQ ; Second S nonIntraSearchP ; Second S nonIntraSearchQ ; Second S SearchDeltaP ; Second S SearchDeltaP-Stationary ; Second S SearchThresholdP ; Second S SearchThresholdP2 ; S SearchThresholdQ ; and / or a second S SearchThresholdQ2 .

[0148] At 618, the first UE 604 determines to perform cell selection / reselection measurements based on the first parameter, threshold, and / or priority. At 620, the second UE 606 determines to perform cell selection / reselection measurements based on the first parameter, threshold, and / or priority.

[0149] Thus, at 622 and 624, the first UE 604 and the second UE 606 may respectively receive and measure one or more measurement reference signals (MRS) from the network entity 602. It should be understood that although Figure 6 6 shows cell selection using network entity 602, but the UE may perform measurements on signals from different network entities and may perform cell selection and reselection using different network entities. In addition, it should be understood that the UE may perform measurements on the same or different cells and / or network entities, may perform measurements on the same or different MRs, and may perform measurements at the same time or at different times.

[0150] At 626, the first UE 604 performs cell selection and / or cell reselection based on the measurement (performed at 622) and the first parameter based on the first one or more capabilities, thresholds, and / or priorities (determined at 614) from the first system information. Figure 5 , the first UE 604 may perform measurements on the cell (e.g., at 502, 504, 510, and 512). In some examples, the first UE 604 performs cell measurements based on threshold measurements of the serving cell. In some cases, a threshold for measuring a cell based on measurements of the serving cell is provided in the first system information, and the UE uses the first system information based on determining the first one or more capabilities. In addition, as described above, for the evaluation of the cell measurements (e.g., at 506, 508, 514, 516), the cell selection criteria may be met when Srxlevl>0 and Squal>0, wherein the parameters of Srxlev and Squal are configured in the first system information used by the first UE 604 based on determining the first one or more capabilities. Therefore, the cell selection and reselection performed by the first UE 604 at 626 is based on the parameters and thresholds configured in the first system information received by the first UE 604 at 608, and the first UE 604 uses the parameters and thresholds based on the first UE 604 determining the first one or more capabilities at 610.

[0151] At 628, the second UE 606 performs cell selection and / or cell reselection based on the measurement (performed at 624) and second parameters based on the second one or more capabilities, thresholds, and / or priorities (determined at 616) from the second system information. The cell selection and reselection performed by the second UE 606 at 628 is based on thresholds and parameters that are different from those used by the first UE 604 and configured in the second system information received by the second UE 606 at 608, which the second UE 606 uses based on the second UE 606 determining the second one or more capabilities at 612.

[0152] In some examples, the first UE 604 and the second UE 606 may register with the corresponding (re)selected cells at 630 and 632, respectively, based on the cell (re)selection.

[0153] In some examples, the cell selection at 626 and 628 may be as described above with respect to Figure 5 As described above, cell selection may include evaluating whether Srxlevl>0 and Squal>0 based on determined parameters, thresholds and / or priorities.

[0154] According to certain aspects (not shown), the network entity 602 may exchange capability-dependent system information with another network entity (e.g., with another gNB or CU). For example, the network entity 602 may exchange capability-dependent system information with the other network entity via an F1 or Xn interface. As part of the exchange, the network entity 602 may receive capability-dependent system information from the other network entity. In some examples, the capability-dependent system information is exchanged as part of the served cell information. In some examples, the exchanged capability-dependent system information is considered during target cell selection during a handover procedure.

[0155] It should be understood that although the above Figure 6 Two UEs and two different system information for two different capabilities or capabilities are discussed, but the network entity 602 may provide any number of different system information for any number of different capabilities or combinations of capabilities.
