Technical Field

[0003] Broadly, aspects of the present disclosure relate to wireless communication and relate to techniques and apparatus for joint cell selection and beam / path loss (PL) reference signal update in layer 1 (L1) / layer 2 (L2) - based mobility. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple access technology that is capable of supporting communication with multiple users by sharing available system resources, such as bandwidth, transmit power, etc. Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / Advanced LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard released by the Third Generation Partnership Project (3GPP).

[0005] A wireless communication network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). A user equipment (UE) may communicate with a base station (BS) via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, while the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipments to communicate at the city, national, regional, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhanced set of the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed to better integrate with other open standards by improving spectral efficiency, reducing costs, enhancing services, leveraging new spectrums, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also referred to as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the uplink (UL) to better support mobile broadband Internet access, as well as support beamforming, Multiple-Input Multiple-Output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to grow, there is a need for further improvement in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies. SUMMARY OF THE INVENTION

[0024] Aspects of the present disclosure are more fully described below with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of any other aspect of the present disclosure or in combination with any other aspect. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the present disclosure is intended to cover such an apparatus or method implemented using other structures, functions, or a combination of structures and functions in addition to or different from the aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of the claims.

[0025] Certain aspects of a telecommunications system will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"), and will be illustrated in the drawings. These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0026] It should be noted that although terms commonly associated with 3G and / or 4G wireless technologies may be used herein to describe aspects, aspects of the present disclosure may be applied to communication systems based on other generations (e.g., communication systems of 5G and later, including NR technology).

[0027] Figure 1FIG. is a diagram showing a wireless network 100 in which aspects of the present disclosure may be implemented. The wireless network 100 may be an LTE network or some other wireless network (e.g., a 5G or NR network). The wireless network 100 may include multiple BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0028] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access by UEs with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed user group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 the example shown, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0029] In some aspects, a cell may not necessarily be stationary, and the geographic area of a cell may move according to the location of a mobile BS. In some aspects, BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (e.g., direct physical connections, virtual networks, and / or similar interfaces using any suitable transport network).

[0030] The wireless network 100 may also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send the data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE capable of relaying transmissions for other UEs. In Figure 1 In the example shown in, the relay station 110d may communicate with the macro BS 110a and the UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a repeater, etc.

[0031] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0032] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, e.g., via a wireless or wired backhaul.

[0033] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a user unit, a station, etc. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, a superbook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), an entertainment device (e.g., a music or video device, or a satellite radio unit, etc.), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0034] Some UEs can be considered as Machine Type Communication (MTC) or evolved or enhanced Machine Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node can provide a connection to or from a network (e.g., a wide area network such as the Internet or a cellular network) via, for example, a wired or wireless communication link. Some UEs can be considered as Internet of Things (IoT) devices, and / or can be implemented as NarrowBand IoT (NB-IoT) devices. Some UEs can be considered as Customer Premises Equipment (CPE). The UE 120 can be included inside a housing that houses components of the UE 120 such as a processor component, a memory component, etc.

[0035] In general, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific Radio Access Technology (RAT) and can operate on one or more frequencies. The RAT can also be referred to as a radio technology, an air interface, etc. The frequency can also be referred to as a carrier, a channel, etc. Each frequency can support a single RAT in a given geographical area in order to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0036] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using the base station 110 as an intermediary for communicating with each other). For example, the UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which can include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), a mesh network, etc. In such cases, the UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0037] In some aspects, Figure 1A wireless communication device (e.g., base station 110, UE 120, network controller 130, etc.) can perform one or more operations associated with joint cell selection and beam and / or PL reference signal (hereinafter referred to as beam / PL reference signal) update in L1 / L2-based mobility, as described herein. For example, base station 110 can identify a cell that has been selected to serve UE 120, and can provide a joint indication to the UE, the joint indication including information associated with the cell that has been selected to serve the UE, information associated with one or more beams to be used for the cell, and / or information associated with one or more PL reference signals to be used for one or more beams. Here, UE 120 can receive the joint indication from the base station, and can communicate in the cell at least in part based on the joint indication (e.g., at least in part based on information associated with the cell and at least one of information associated with one or more beams to be used for the cell or one or more PL reference signals to be used for one or more beams).

[0038] As noted above, Figure 1 is provided as an example. Other examples may be different from those Figure 1 described with respect to

[0039] Figure 2 shows a block diagram of a design 200 of base station 110 and UE 120 (which can be Figure 1 one of the base stations in

[0040] At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCSs) for the UE at least in part based on channel quality indicators (CQIs) received from each UE, process (e.g., encode and modulate) the data for the UE at least in part based on the MCSs selected for each UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRSs)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable) and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process the corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively. According to various aspects described in more detail below, synchronization signals may be generated using position coding to convey additional information.

[0041] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide the received signals to demodulators (DEMOD) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The channel processor may determine the reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0042] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antennas 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0043] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component in may perform one or more techniques associated with joint cell selection and beam and / or PL reference signal updates in L1- and / or L2-based mobility, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in may perform or direct, for example Figure 4 the operation of process 400, Figure 5 the operation of process 500, and / or the operation of other processes as described herein. The memories 242 and 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, when executed by one or more processors of the base station 110 and / or the UE 120, the one or more instructions may perform or direct, for example Figure 4 the operation of process 400, Figure 5 the operation of process 500, and / or the operation of other processes described herein. The scheduler 246 may schedule the UE for data transmission on the downlink and / or uplink.

[0044] In some aspects, the base station 110 may include: a unit for identifying the cell that has been selected to serve the UE 120; a unit for providing a joint indication to the UE 120, the joint indication including information associated with: the cell that has been selected to serve the UE 120, one or more beams to be used for the cell, or one or more PL reference signals to be used for one or more beams; and so on. In some aspects, such a unit may include one or more components of the base station 110 described in conjunction with Figure 2 such as the antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0045] In some aspects, the UE 120 may include: a unit for receiving a joint indication from the base station 110, the joint indication including information associated with: the cell that has been selected to serve the UE 120, one or more beams to be used for the cell, or one or more PL reference signals to be used for one or more beams; a unit for communicating in the cell based at least in part on the joint indication; and so on. In some aspects, such a unit may include one or more components of the UE 120 described in conjunction with Figure 2One or more components of the described UE 120, such as the controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0046] As noted above, Figure 2 is provided as an example. Other examples may be different from those Figure 2 described herein.

[0047] In some wireless communication systems (such as NR systems), a set of mechanisms for a UE and a base station to establish a directional link (e.g., using a high-dimensional phased array) may be useful (e.g., for benefiting from beamforming gain and / or for maintaining acceptable communication quality). However, such a directional link requires precise alignment of the transmit beam and the receive beam. This alignment can be achieved through a set of operations called beam management.

[0048] In addition, a wireless communication system may support multi-beam operation at a relatively high carrier frequency (e.g., within frequency range 2 (FR2)). In such a case, compared with a relatively low carrier frequency, the higher carrier frequency makes the propagation conditions more adverse. For example, compared with the sub-6 gigahertz (GHz) band, signals propagating in the millimeter wave band may suffer increased path loss and severe channel intermittency, and / or may be blocked by objects (e.g., buildings, trees, user bodies, etc.) that are typically present in the UE's environment. Therefore, beam management is particularly important for multi-beam operation at a relatively high carrier frequency.

[0049] One possible enhancement for multi-beam operation at a higher carrier frequency is to facilitate efficient (e.g., low latency and low overhead) beam management to support higher L1 / L2-centric inter-cell mobility. For example, when a multi-beam UE operating in FR2 moves from one or more first cells to one or more second cells, L1 / L2-centric inter-cell mobility can be used. It is worth noting that due to the operation in FR2, such cell handovers can be used regularly. Many operation modes for L1 / L2-centric inter-cell mobility have been proposed. One goal of L1 / L2-centric inter-cell mobility is to enable the UE to perform cell handovers via lower layers (e.g., L1 and / or L2) rather than higher layers, which improves the efficiency of cell handovers (e.g., by reducing latency and overhead).

[0050] In an L1 / L2-centric inter-cell mobility scenario with multi-beam operation, when a base station selects a cell for serving a UE, the base station indicates the selected cell to the UE. Additionally, the base station may signal information associated with operations in the cell, such as information associated with one or more beams (e.g., one or more downlink beams and / or one or more uplink beams) to be used for the cell and / or information associated with one or more path loss (PL) reference signals to be used for the cell (e.g., for uplink power control). Currently, the base station separately indicates the selected cell, the information associated with one or more beams, and the information associated with one or more PL reference signals (e.g., the base station may provide a first downlink control information (DCI) for indicating cell selection, a second DCI for beam update / activation, and a third DCI for PL reference signal activation). However, transmitting such information in multiple transmissions is inefficient (e.g., in terms of latency and signaling overhead, which is particularly undesirable in an L1 / L2-centric inter-cell mobility scenario).

[0051] Some aspects described herein provide techniques and apparatus for joint cell selection and beam / PL reference signal update in L1 / L2-based mobility. In some aspects, a base station may provide a joint indication and a UE may receive the joint indication, the joint indication including information associated with a cell that has been selected for serving the UE and information associated with at least one of one or more beams to be used for the cell or one or more PL reference signals to be used for one or more beams. In some aspects, such a joint indication may improve the efficiency of cell handover via lower layers (e.g., L1 and / or L2) by reducing latency and / or overhead.

[0052] Figure 3 is a diagram of an example associated with joint cell selection and beam / PL reference signal update in L1 / L2-based mobility in accordance with various aspects of the present disclosure.

[0053] As shown by reference numeral 305, a base station (e.g., base station 110) may identify (e.g., using receive processor 238, controller / processor 240, memory 242, identification component 608, etc.) the cell that has been selected to serve a UE (e.g., UE 120). In some aspects, the base station may identify the cell that has been selected to serve a UE at least in part based on cell selection / deselection performed by the base station. For example, in some aspects, the base station may select or deselect a given cell for serving a UE based on the reference signal received power (RSRP) associated with the given cell (e.g., RSRP for each reported synchronization signal block (SSB) identifier, RSRP for each reported SSB identifier for each physical cell identifier (PCI), etc.). Here, when the base station selects a given cell for serving a UE, the base station may identify the given cell as the cell selected to serve the UE. Alternatively, in some aspects, the base station may identify the cell that has been selected to serve a UE at least in part based on an indication received from the UE (e.g., when the UE performs cell selection / deselection and provides an indication of the multiple selected / deselected cells to the base station). In some aspects, the base station may identify one or more additional cells selected to serve a UE in this manner. That is, in some aspects, the base station may identify multiple cells selected to serve a UE.

[0054] In some aspects, the manner of identifying a cell for serving a UE may depend on the operating mode of L1 / L2-centric inter-cell mobility. A first example of an operating mode may include an operating mode in which each serving cell has one physical cell identifier (PCI) and may have multiple physical cell sites (e.g., remote radio heads (RRHs)). Here, each RRH may transmit a different set of synchronization signal block (SSB) identifiers, but has the same PCI for the serving cell. In this operating mode, downlink control information (DCI) or medium access control element (MAC-CE) may indicate, at least in part, one or more RRHs or corresponding SSBs selected for serving the UE based on the RSRP of each reported SSB identifier. A second example of an operating mode includes an operating mode in which each serving cell may be configured with multiple PCIs and each RRH of the serving cell may use one of the PCIs configured for the serving cell and may transmit a complete set of SSB identifiers. Here, DCI or MAC-CE may indicate, at least in part, one or more RRHs or one or more corresponding PCIs and / or SSBs selected for serving the UE based on the RSRP of each reported SSB identifier of each reported PCI. A third example of an operating mode may include an operating mode in which each serving cell has one PCI. Here, DCI or MAC-CE may indicate, based on the RSRP of each reported SSB identifier of each reported PCI, one or more serving cells or corresponding serving cell identifiers selected for serving the UE. It should be noted that although SSBs are described in the above examples, the SSB may be another type of cell-defined reference signal (e.g., channel state information reference signal (CSI-RS), positioning reference signal (PRS), etc.).

[0055] As shown by reference numeral 310, the base station may provide (e.g., using the transmit processor 220, the controller / processor 240, the memory 242, the transmit component 604, etc.) a joint indication that includes information associated with the cell that has been selected for serving the UE. Here, the joint indication also includes information associated with one or more beams to be used for the cell and / or information associated with one or more PL reference signals to be used for one or more beams (e.g., for uplink power control). In some aspects, the joint indication may include information associated with multiple cells selected for serving the UE (e.g., when the base station identifies multiple cells selected for serving the UE).

[0056] As shown by reference numeral 310, the UE may receive (e.g., using the receiving processor 258, the controller / processor 280, the memory 282, the receiving component 702, etc.) a joint indication provided by the base station. In some aspects, the base station may provide the joint indication via downlink control information (DCI), a media access control control element (MAC-CE), etc., and the UE may receive the joint indication.

[0057] In some aspects, the information associated with a given cell included in the joint indication may include information identifying the cell. The information identifying the cell may include, for example, a physical cell identifier (PCI), a serving cell identifier, etc.

[0058] In some aspects, when the joint indication includes information associated with one or more beams to be used for a cell, the downlink beam may be indicated by an activated transmission configuration indicator (TCI) state identifier included in the joint indication. In some aspects, the downlink beam may be a beam to be used for a physical downlink control channel (PDCCH), and the activated TCI state identifier may be associated with a control resource set (CORESET) identifier. That is, in some aspects, for the PDCCH, the beam may be indicated by the activated TCI state identifier of each CORESET identifier. In some aspects, the downlink beam may be a beam to be used for a physical downlink shared channel (PDSCH). That is, in some aspects, for the PDSCH, the beam may be indicated by the activated TCI state identifier of the PDSCH. In some aspects, the downlink beam may be a beam to be used for a default PDSCH beam. When the scheduling offset between the DCI and the scheduled PDSCH is less than the beam switching latency threshold, the default PDSCH beam may be used. That is, in some aspects, for the default PDSCH, the beam may be indicated by the activated TCI state identifier.

[0059] In some aspects, when the joint indication includes information associated with one or more beams to be used for a cell, the uplink beam may be indicated by activated spatial relation information associated with an uplink resource. In some aspects, the uplink beam may be a beam to be used for a physical uplink control channel (PUCCH) or a sounding reference signal (SRS). That is, in some aspects, for the PUCCH / SRS, the beam may be indicated by the activated spatial relation information of each PUCCH / SRS resource.

[0060] In some aspects, when the joint indication includes information associated with one or more beams to be used for a cell, the uplink beam can be indicated by an active uplink TCI state identifier. In some aspects, the uplink beam can be a beam to be used for PUCCH, SRS, Physical Uplink Shared Channel (PUSCH), or Physical Random Access Channel (PRACH). That is, in some aspects, for PUCCH / SRS / PUSCH / PRACH, the beam can be indicated by an active uplink TCI state identifier.

[0061] In some aspects, when the joint indication includes information associated with one or more PL reference signals for one or more beams, the PL reference signal identifier can be indicated for each PUCCH resource identifier. That is, in some aspects, the PL reference signal identifier can be indicated for each PUCCH resource identifier.

[0062] In some aspects, when the joint indication includes information associated with one or more PL reference signals for one or more beams, the PL reference signal identifier can be indicated for each SRS resource set identifier. That is, in some aspects, the PL reference signal identifier can be indicated for each SRS resource set identifier.

[0063] In some aspects, when the joint indication includes information associated with one or more PL reference signals for one or more beams, the PL reference signal identifier can be indicated for each PUSCH. That is, in some aspects, the PL reference signal identifier can be indicated for each PUSCH transmission.

[0064] In some aspects, when the joint indication includes information associated with one or more PL reference signals for one or more beams, the PL reference signal identifier can be indicated for each SRS resource indicator (SRI). That is, in some aspects, the PL reference signal identifier can be indicated for each SRI associated with a PUSCH transmission.

[0065] In some aspects, the cell selected to serve the UE is the first cell selected to serve the UE, and the information included in the joint indication (e.g., information associated with one or more beams and / or information associated with one or more PL reference signals) can be information to be used for a second cell that has been selected to serve the UE. That is, in some aspects, one or more beams (e.g., one or more downlink beams and / or one or more uplink beams) and / or one or more PL reference signals indicated by the joint indication can be applied to multiple cells selected to serve the UE.

[0066] In some aspects, the information included in the joint indication can be used by the second cell at least in part based on the first cell and the second cell being included in a cell list preconfigured on the UE. For example, in some aspects, multiple cell lists can be preconfigured on the UE. Here, when one or more beams and / or one or more PL reference signals are indicated for the first cell on a given cell list among the multiple preconfigured cell lists, the same one or more beams and / or one or more PL reference signals can be applied to other selected cells in the given cell list. More specifically, the same indicated identifier of the TCI state, spatial relation, uplink TCI state, and / or PL reference signal can be applied to the same indicated identifier of the CORESET, PUCCH resource, and / or SRS resource set, or can be applied to the same indicated usage for PDSCH or PUSCH transmission on other selected cells in the same cell list.

[0067] In some aspects, the information included in the joint indication can be used by the second cell at least in part based on the first cell and the second cell being included in a selected cell list identifying the first cell and the second cell. In some aspects, the selected cell list can be transmitted to the UE via a joint indication, DCI, MAC-CE, etc. That is, in some aspects, one or more beams and / or one or more PL reference signals can be indicated for the selected cell list.

[0068] In some aspects, the information included in the joint indication can be used by the second cell at least in part based on the first cell and the second cell being included in a cell group including the first cell and the second cell. In some aspects, information identifying the cell group (e.g., cell group identifier) can be transmitted to the UE via a joint indication, DCI, MAC-CE, etc. That is, in some aspects, one or more beams and / or one or more PL reference signals can be indicated for selected cells included in the identified cell group.

[0069] In some aspects, the second cell serving the UE can be identified at least in part based on the UE capability, which indicates whether the UE supports cells in which frequency ranges allow sharing the same beam or the same PL reference signal.

[0070] As shown by reference numeral 315, the UE may communicate in a cell based at least in part on the joint indication (e.g., using the receive processor 258, transmit processor 264, controller / processor 280, memory 282, receive component 702, transmit component 704, etc.). For example, the UE may receive one or more communications (e.g., PUCCH communication, PUSCH communication, SRS, PRACH communication, etc.) based at least in part on information associated with one or more beams included in the joint indication. As another example, the UE may transmit one or more communications (e.g., PDSCH communication, PDCCH communication) based at least in part on information associated with one or more beams included in the joint indication. As another example, the UE may receive one or more PL reference signals based at least in part on information associated with one or more PL reference signals to be used for the cell included in the joint indication. In some aspects, the cell in which the UE communicates based at least in part on the joint indication may be the same cell as the cell in which the joint indication is provided to the UE. Alternatively, in some aspects, the cell in which the UE communicates based at least in part on the joint indication may be a different cell from the cell in which the joint indication is provided to the UE.
