Field of the Disclosure

[0003] Broadly speaking, aspects of the present disclosure relate to wireless communication, and more particularly, aspects of the present disclosure relate to techniques and apparatus for indicating user equipment (UE) capabilities for simultaneous beam update across multiple component carriers. 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 use multiple access technologies that are capable of supporting communication with multiple users by sharing available system resources (e.g., 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 standards released by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include several base stations (BSs) capable of supporting communication for several 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, and 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 refer to a Node B, a gNB, an access point (AP), a radio head, a transmission reception point (TRP), a new radio (NR) BS, a 5G Node B, and / or the like.

[0006] The above multi-access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipments to communicate at the urban, 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 3rd Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, utilizing new spectrums, and better integrating with other open standards that use orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., which may also be referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other wireless access technologies, as well as the telecommunication standards that employ these technologies, remain useful. SUMMARY OF THE INVENTION

[0007] In some aspects, a method of wireless communication performed by a user equipment (UE) may include: sending information to a base station for indicating the UE's ability to support simultaneous beam updates across multiple component carriers; receiving, at least in part based on the UE's ability to support the simultaneous beam updates across multiple component carriers, a beam update command from the base station, the beam update command identifying the component carriers configured for the UE; and applying, at least in part based on the component carriers identified in the beam update command, the beam update command to one or more component carriers.

[0008] In some aspects, a method of wireless communication performed by a base station may include: receiving, from a UE, information for indicating the UE's ability to support simultaneous beam updates across multiple component carriers; and sending, at least in part based on the UE's ability to support the simultaneous beam updates across multiple component carriers, a beam update command to the UE, the beam update command identifying the component carriers configured for the UE.

[0009] In some aspects, a UE for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to: send information to a base station for indicating the UE's ability to support simultaneous beam updates across multiple component carriers; receive a beam update command from the base station at least in part based on the UE's ability to support the simultaneous beam updates across multiple component carriers, the beam update command identifying the component carriers configured for the UE; and apply the beam update command to one or more component carriers at least in part based on the component carriers identified in the beam update command.

[0010] In some aspects, a base station for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to: receive information from a UE for indicating the UE's ability to support simultaneous beam updates across multiple component carriers; and send a beam update command to the UE at least in part based on the UE's ability to support the simultaneous beam updates across multiple component carriers, the beam update command identifying the component carriers configured for the UE.

[0011] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. When executed by one or more processors of a UE, the one or more instructions may cause the one or more processors to: send information to a base station for indicating the UE's ability to support simultaneous beam updates across multiple component carriers; receive a beam update command from the base station at least in part based on the UE's ability to support the simultaneous beam updates across multiple component carriers, the beam update command identifying the component carriers configured for the UE; and apply the beam update command to one or more component carriers at least in part based on the component carriers identified in the beam update command.

[0012] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. When executed by one or more processors of a base station, the one or more instructions may cause the one or more processors to: receive information from a UE for indicating the UE's ability to support simultaneous beam updates across multiple component carriers; and send a beam update command to the UE at least in part based on the UE's ability to support the simultaneous beam updates across multiple component carriers, the beam update command identifying the component carriers configured for the UE.

[0013] In some aspects, a device for wireless communication may include: a unit for sending information to a base station for indicating the device's ability to support simultaneous beam updates across multiple component carriers; a unit for receiving a beam update command from the base station at least partially based on the device's ability to support the simultaneous beam updates across multiple component carriers, the beam update command identifying the component carriers configured for the device; and a unit for applying the beam update command to one or more component carriers at least partially based on the component carriers identified in the beam update command.

[0014] In some aspects, a device for wireless communication may include: a unit for receiving from a UE information for indicating the UE's ability to support simultaneous beam updates across multiple component carriers; and a unit for sending a beam update command to the UE at least partially based on the UE's ability to support the simultaneous beam updates across multiple component carriers, the beam update command identifying the component carriers configured for the UE.

[0015] In some aspects, the information for indicating the UE's ability to support the simultaneous beam updates across multiple component carriers indicates whether the UE supports simultaneous transmission configuration indication (TCI) state updates across multiple component carriers.

[0016] In some aspects, at least partially based on the UE's support for the simultaneous TCI state updates across multiple component carriers, the beam update command identifies the TCI states to be simultaneously activated across multiple component carriers for a downlink reception beam associated with one or more of a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH).

[0017] In some aspects, the information for indicating the UE's ability to support the simultaneous beam updates across multiple component carriers indicates the maximum number of component carrier lists that can be configured for the UE to support the simultaneous TCI state updates across multiple component carriers.

[0018] In some aspects, the information for indicating the UE's ability to support the simultaneous beam updates across multiple component carriers indicates whether the UE supports simultaneous spatial relation updates for uplink transmission beams across multiple component carriers.

[0019] In some aspects, at least partially based on the UE's support for the simultaneous spatial relation updates across multiple component carriers, the beam update command identifies the spatial relations to be simultaneously activated across multiple component carriers for an uplink transmission beam associated with one or more of an aperiodic or semi-periodic sounding reference signal.

[0020] In some aspects, the information indicating the ability of the UE to support the simultaneous beam update across multiple component carriers indicates the maximum number of component carrier lists that can be configured for the UE to support the simultaneous spatial relation update across multiple component carriers.

[0021] In some aspects, the information indicating whether the UE supports the simultaneous spatial relation update across multiple component carriers is only applied to the component carriers associated with one or more of the millimeter wave frequency range or the time division duplex configuration.

[0022] In some aspects, the beam update command is to be applied to multiple component carriers in a component carrier list, the component carrier list including the component carriers identified in the beam update command at least partially based on the UE supporting the simultaneous beam update across multiple component carriers.

[0023] Aspects generally include methods, apparatuses, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication devices, and / or processing systems, as fully described herein with reference to the figures and the specification and as illustrated in the figures and the specification.

[0032] Aspects of the present disclosure are described more fully hereinafter 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 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 disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the present disclosure. 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 that uses other structures, functions, or 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 disclosure disclosed herein may be embodied by one or more elements of the claims.

[0033] Certain aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the detailed description below and illustrated in the drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). 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.

[0034] It should be noted that although terms typically associated with 5G or NR radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or RATs after 5G (e.g., 6G).

[0035] Figure 1 FIG. is a diagram illustrating an example of a wireless network 100 in accordance with aspects of the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network, an LTE network, etc. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE), and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, depending on the context in which the term "cell" is used, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area.

[0036] The BS may provide communication coverage for macro cells, pico cells, femto cells, 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 service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber 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.

[0037] In some aspects, the cell may not necessarily be stationary, and the geographical area of the cell may move according to the position of the mobile BS. In some aspects, the BSs may use any suitable transmission network to interconnect with each other and / or to one or more other BSs or network nodes (not shown) in the radio network 100 through various types of backhaul interfaces (e.g., direct physical connections, virtual networks, etc.).

[0038] The radio network 100 may also include relay stations. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In Figure 1 the example shown, the relay BS 110d may communicate with the macro BS 110a and the UE 120d to facilitate communication between the BS 110a and the UE 120d. The relay BS may also be referred to as a relay station, a relay base station, a repeater, etc.

[0039] The radio 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 radio network 100. For example, a macro BS may have a higher 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).

[0040] 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 the backhaul. The BSs may also communicate with each other directly or indirectly via a wireless backhaul or a wired backhaul.

[0041] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, terminal, mobile station, user unit, station, etc. A UE can 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 equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio device), a vehicle-mounted 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 medium or a wired medium.

[0042] Some UEs can be regarded 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. that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, 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 a wired or wireless communication link. Some UEs can be regarded as Internet of Things (IoT) devices, and / or can be implemented as narrowband IoT (NB-IoT) devices. Some UEs can be regarded as customer premises equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120 (e.g., a processor component, a memory component, etc.). In some aspects, the processor component and the memory component can be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., a memory) can be operatively coupled, communicatively coupled, electronically coupled, electrically coupled, etc.

[0043] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a wireless technology, an air interface, etc. A frequency can also be referred to as a carrier, a frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0044] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using the base station 110 as an intermediate device to communicate with each other). For example, UEs 120 may communicate using the following: peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, and so on. In such cases, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as performed by the base station 110.

[0045] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) (which may span from 410 MHz to 7.125 GHz), and / or may communicate using an operating band having a second frequency range (FR2) (which may span from 24.25 GHz to 52.6 GHz). Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the “sub-6 GHz” band. Similarly, although different from the extremely high frequency (EHF) band (30 GHz - 300 GHz), which is identified by the International Telecommunication Union (ITU) as the “millimeter wave” band, FR2 is generally referred to as the “millimeter wave” band. Thus, unless otherwise specifically stated, it should be understood that if the term “sub-6 GHz” etc. is used herein, it may broadly represent frequencies that may be less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that if the term “millimeter wave” etc. is used herein, it may broadly represent frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein apply to those modified frequency ranges.

[0046] As noted above, Figure 1 is provided as an example. Other examples may be different from the example regarding Figure 1 described.

[0047] Figure 2FIG. 200 is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network in accordance with various aspects of the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where generally, T≥1 and R≥1.

[0048] At the base station 110, a transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCSs) for the UE at least in part based on a channel quality indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for the UE at least in part based on the MCS selected for each UE, and provide data symbols for all UEs. The 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. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS), demodulation reference signal (DMRS), etc.) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). A 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 provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process its respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process the output sample stream (e.g., convert to analog, amplify, filter, and upconvert) to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via the T antennas 234a through 234t, respectively.

[0049] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations, and may respectively provide the received signals to demodulators (DEMOD) 254a through 254r. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain input samples. Each demodulator 254 may also process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from all R demodulators 254a through 254r, perform MIMO detection (if applicable) on the received symbols, and provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine 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 the housing 284.

[0050] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0051] 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. The symbols from the transmit processor 264 may be precoded (if applicable) by the TX MIMO processor 266, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0052] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected (if applicable) by MIMO detector 236, and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 can include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 can include scheduler 246 for scheduling UE 120 for downlink and / or uplink communication. In some aspects, base station 110 includes a transceiver. The transceiver can include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0053] Controller / processor 240 of base station 110, controller / processor 280 of UE 120, and / or Figure 2 any other components thereof can perform one or more techniques associated with indicating the capabilities of UE 120 for simultaneous beam updates across multiple component carriers, as described in more detail elsewhere herein. For example, controller / processor 240 of base station 110, controller / processor 280 of UE 120, and / or Figure 2 any other components thereof can execute or direct, for example, Figure 4 process 400, Figure 5 process 500, and / or the operation of other processes as described herein. Memories 242 and 282 can store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 can include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, when executed (e.g., directly, or after compilation, conversion, interpretation, etc.) by one or more processors of base station 110 and / or UE 120, the one or more instructions can cause one or more processors, UE 120, and / or base station 110 to execute or direct, for example, Figure 4 process 400, Figure 5 process 500, and / or the operation of other processes as described herein. In some aspects, executing the instructions can include running the instructions, converting the instructions, compiling the instructions, interpreting the instructions, etc.

[0054] In some aspects, the UE 120 may include: a unit for sending information to the base station 110 indicating the UE 120's ability to support simultaneous beam updates across multiple component carriers; a unit for receiving a beam update command from the base station 110 at least partially based on the UE 120's ability to support simultaneous beam updates across multiple component carriers, the beam update command identifying the component carriers configured for the UE 120; a unit for applying the beam update command to one or more component carriers at least partially based on the component carriers identified in the beam update command; and so on. In some aspects, such units may include one or more components of the UE 120 described in conjunction with Figure 2 such as the controller / processor 280, transmit processor 264, TX MIMO processor 266, modulator 254, antenna 252, demodulator 254, MIMO detector 256, receive processor 258, etc.

[0055] In some aspects, the base station 110 may include: a unit for receiving information from the UE 120 indicating the UE 120's ability to support simultaneous beam updates across multiple component carriers; a unit for sending a beam update command to the UE 120 at least partially based on the UE 120's ability to support simultaneous beam updates across multiple component carriers, the beam update command identifying the component carriers configured for the UE 120; and so on. In some aspects, such units may include one or more components of the base station 110 described in conjunction with Figure 2 such as the antenna 234, demodulator 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, modulator 232, antenna 234, etc.

[0056] As noted above, Figure 2 is provided as an example. Other examples may be different from the examples described with respect to Figure 2 which is described.

[0057] Wireless communication devices (such as UEs, base stations, transmission and reception points (TRPs), etc.) can communicate with each other using beams. For example, a beam can be defined using a transmission configuration indicator (TCI) state associated with a downlink transmission beam used by a base station or TRP and a corresponding downlink reception beam to be used by a UE. For example, the TCI state of a beam can indicate the source reference signal and the quasi-collocation (QCL) type to be used for the beam. The QCL type can correspond to one or more QCL relationships, which indicate how the source reference signal is to be quasi-collocated (QCL) with the channel on the beam. Two antenna ports are said to be QCL if the properties of the channel on which the symbols on one antenna port are transmitted (e.g., the channel on the beam) can be inferred from the channel on which the symbols on the other antenna port are transmitted (e.g., the source reference signal). Additionally or alternatively, a beam can be defined based on a spatial relationship. In this case, the spatial relationship can indicate the uplink transmission beam to be used by the UE and the corresponding uplink reception beam to be used by the base station or TRP.

[0058] In some cases, the base station and / or the UE can perform downlink and / or uplink beam management. In this case, the base station can configure one or more beam management parameters for the UE, activate and / or deactivate one or more uplink and / or downlink beams, etc. As an example, the base station can configure, activate, deactivate, and / or otherwise update uplink and / or downlink TCI states, such as physical downlink control channel (PDCCH) TCI state, physical downlink shared channel (PDSCH) TCI state, channel state information reference signal (CSI-RS) TCI state, physical uplink control channel (PUCCH) TCI state, physical uplink shared channel (PUSCH) TCI state, physical random access channel (PRACH) TCI state, sounding reference signal (SRS) TCI state, etc. As another example, the base station can configure, activate, deactivate, and / or otherwise update uplink spatial relationships (e.g., which can include indications of beam and / or base station collocation, quasi-collocation, etc.), such as PUCCH spatial relationship, SRS spatial relationship, etc.

[0059] In some cases, a UE and a base station (or any other suitable transmitter device and receiver device) may perform beam management to establish and / or refine beam management parameters and / or reference signal parameters. Thus, beam management can enable in-cell mobility (e.g., when the physical orientation of the UE changes, when clusters or blocking objects in the channel change, etc.) and inter-cell mobility (e.g., when the UE is handed over from one base station to another base station) and other processes. In some cases, the beam management procedure may be inefficient. For example, in some cases, the UE and the base station may communicate using carrier aggregation, which is a technique that enables multiple component carriers (CCs, sometimes referred to as carriers) to be combined (e.g., combined into a single channel) for a single UE to enhance data capacity.

[0060] For example, carriers can typically be combined in the same or different frequency bands, the same or different frequency ranges, etc. Additionally or alternatively, contiguous or non-contiguous carriers can be combined. For example, carrier aggregation can be configured in an in-band contiguous mode, where the aggregated carriers are adjacent to each other and in the same frequency band. Additionally or alternatively, carrier aggregation can be configured in an in-band non-contiguous mode, where the aggregated carriers are non-contiguous with each other and in the same frequency band. Additionally or alternatively, carrier aggregation can be configured in an inter-band non-contiguous mode, where the aggregated carriers are non-contiguous with each other and in different frequency bands. In these and other carrier aggregation cases, performing beam management separately for each component carrier may be inefficient. For example, latency and overhead may be involved when sending and applying multiple beam update commands for different component carriers.

[0061] A technique for reducing the overhead and / or inefficiencies of performing beam management in a carrier aggregation scenario is to implement simultaneous beam updates across multiple component carriers. For example, each component carrier configured for a UE can be associated with a downlink receive beam and an uplink transmit beam, and in some cases, the component carriers configured for the UE can be close to each other in frequency. Thus, if the UE is to use a particular receive beam and / or transmit beam in one component carrier, the UE can also use the same receive beam and / or transmit beam in other component carriers (e.g., adjacent component carriers). In this way, the efficiency of the beam management process can be improved by simultaneously updating beam information across multiple component carriers. However, in some cases, the UE may not generally support simultaneously applying beam update commands across multiple component carriers (e.g., the UE may only support updating the beam for a single component carrier, may only support simultaneously updating the uplink transmit beam across different component carriers, may only support simultaneously updating the downlink receive beam across different component carriers, may have different support configurations for simultaneously updating the uplink transmit beam and the downlink receive beam across different component carriers, etc.). In this regard, without knowing the beam update capabilities (if any) supported by the UE, the base station and the UE may not be able to achieve the efficiency of simultaneous beam updates across multiple component carriers.

[0062] Figure 3 FIG. 300 is a diagram illustrating an example 300 of UE capabilities indicating simultaneous beam updates across multiple component carriers in accordance with various aspects of the present disclosure. As Figure 3 shown, example 300 includes UE 120 communicating with base station 110 over a wireless network (e.g., wireless network 100). In some aspects, as described herein, UE 120 and base station 110 may communicate using carrier aggregation across multiple component carriers. Additionally, in some aspects, as described herein, UE 120 and base station 110 may communicate using beams in each component carrier. For example, in each component carrier, UE 120 may use an uplink transmit beam associated with a spatial relationship, and base station 110 may use an uplink receive beam associated with a spatial relationship. Similarly, in each component carrier, UE 120 may use a downlink receive beam associated with a TCI state, and base station 110 may use a downlink transmit beam associated with a TCI state. Thus, as described herein, UE 120 may signal to base station 110 the ability to simultaneously apply beam update commands (e.g., regarding spatial relationships and / or TCI states) across multiple component carriers.

[0063] For example, as in Figure 3As shown in and by reference numeral 310 in the figure, the UE 120 may send and the base station 110 may receive information indicating the ability of the UE 120 to support simultaneous beam updates across multiple component carriers. In some aspects, the UE 120 may separately indicate the ability to support simultaneous beam updates across multiple component carriers for a TCI state, and the ability to support simultaneous beam updates across multiple component carriers for a spatial relationship. For example, with respect to the TCI state, the indicated ability may indicate whether the UE 120 supports simultaneously applying beam update commands to update the downlink reception beams for receiving the physical downlink control channel (PDCCH) and / or the physical downlink shared channel (PDSCH) across multiple component carriers. Similarly, for the spatial relationship, the indicated ability may indicate whether the UE 120 supports simultaneously applying beam update commands to update the uplink transmission beams for transmitting aperiodic or semi-periodic sounding reference signals (SRS). Additionally, in some aspects, the indicated ability to simultaneously update the spatial relationship may apply only to component carriers in the millimeter wave frequency range (e.g., frequency range 2 (FR2)) and / or component carriers having a time division duplex (TDD) configuration.

[0064] In some aspects, the ability information sent to the base station 110 may additionally or alternatively (e.g., via radio resource control (RRC) signaling) indicate the maximum number of component carrier lists configured for the UE 120. For example, the UE 120 may be configured with up to two component carrier lists that can be simultaneously managed during the beam update process. Thus, in some aspects, the UE 120 may indicate the maximum number of component carrier lists configured for the UE 120 that the UE 120 supports simultaneous beam updates for, where the set of candidate values for the maximum number of component carrier lists may be {0, 1, 2}. In this case, if the UE 120 indicates zero (0) as the maximum configured number of component carrier lists supporting simultaneous TCI state activation across multiple component carriers, the base station 110 may interpret this indication to mean that the UE 120 does not support simultaneous TCI state activation across multiple component carriers. Similarly, if the UE 120 indicates zero (0) as the maximum configured number of component carrier lists supporting simultaneous update of the spatial relationship across multiple component carriers, the base station 110 may interpret this indication to mean that the UE 120 does not support simultaneous update of the spatial relationship across multiple component carriers. However, when the UE 120 indicates that the maximum configured number of component carrier lists supporting simultaneous TCI state activation and / or spatial relationship update is one (1) or two (2), the beam update commands for identifying any component carrier in the list may be applied to all component carriers in the list.

[0065] As in Figure 3As shown further in and by reference numeral 320, at least in part based on the ability of UE 120 to support simultaneous beam updates across multiple component carriers, base station 110 may send and UE 120 may receive a beam update command that identifies the component carriers configured for UE 120. For example, in some aspects, the beam update command may identify the component carriers configured for UE 120 and may also indicate an updated TCI state to be activated for the downlink receive beam associated with the component carrier, and / or an updated spatial relation to be applied to the uplink transmit beam associated with the component carrier. Additionally, in the case where UE 120 indicates the ability to support simultaneous TCI state activation and / or simultaneous spatial relation updates across multiple component carriers, base station 110 may update each corresponding downlink transmit beam associated with the updated TCI state, and / or each corresponding uplink receive beam associated with the updated spatial relation. For example, base station 110 may identify a list of component carriers configured for UE 120 that includes the component carriers identified in the beam update command, and apply the updated TCI state and / or the updated spatial relation to each component carrier in the same list of component carriers. Alternatively, in the case where UE 120 indicates a lack of support for simultaneous TCI state activation and / or simultaneous spatial relation updates, base station 110 may update only the downlink transmit beam and / or the uplink receive beam associated with the component carrier identified in the beam update command.

[0066] As shown in Figure 3 and further by reference numeral 330, UE 120 may apply the beam update command at least in part based on the component carriers identified in the beam update command. For example, in the case where the component carriers identified in the beam update command are included in one or more configured lists of component carriers that support simultaneous TCI state activation and / or simultaneous spatial relation updates, UE 120 may apply the beam update command to each component carrier in the same list as the component carriers identified in the beam update command. Additionally, in some aspects, the beam update command may include a TCI state to be activated for the component carriers identified in the beam update command and / or an updated spatial relation to be applied to the component carriers identified in the beam update command. In this regard, UE 120 may activate the TCI state indicated in the beam update command and / or apply the updated spatial relation indicated in the beam update command to each component carrier in the same list as the component carriers identified in the beam update command. Alternatively, if UE 120 does not support simultaneous TCI state activation and / or simultaneous spatial relation updates, or the component carriers identified in the beam update command do not appear in a configured list of component carriers that support simultaneous beam updates, then UE 120 may apply the beam update command only to the component carriers identified in the beam update command.

[0067] As shown in Figure 3 and further indicated by reference numeral 340 in the drawings, the UE 120 and the base station 110 may communicate on one or more component carriers using updated beams. For example, in some aspects, the base station 110 may use one or more downlink transmit beams associated with an updated TCI state to transmit PDCCH and / or PDSCH to the UE 120 in one or more component carriers, and the UE 120 may use one or more downlink receive beams associated with the updated TCI state to receive PDCCH and / or PDSCH in one or more component carriers. Additionally or alternatively, the UE 120 may use one or more uplink transmit beams associated with an updated spatial relationship to transmit an aperiodic or semi-periodic SRS to the base station 110 in one or more component carriers associated with a millimeter wave frequency range and / or a TDD configuration, and the base station 110 may use one or more uplink receive beams associated with the updated spatial relationship to receive the aperiodic or semi-periodic SRS in one or more component carriers.

[0068] As noted above, Figure 3 is provided as an example. Other examples may be different from those described with respect to Figure 3 the examples.

[0069] Figure 4 is a diagram illustrating an example process 400, such as may be performed by a UE, in accordance with various aspects of the present disclosure. The example process 400 is an example in which a UE (e.g., UE 120, etc.) performs operations associated with indicating the capabilities of the UE for simultaneous beam updates across multiple component carriers.

[0070] As Figure 4 shown, in some aspects, process 400 may include: sending information to a base station for indicating the capabilities of the UE to support simultaneous beam updates across multiple component carriers (block 410). For example, the UE may send (e.g., using the controller / processor 280, transmit processor 264, TX MIMO processor 266, modulator 254, antenna 252, etc.) information indicating the capabilities of the UE to support simultaneous beam updates across multiple component carriers, as described above.

For example, the UE may apply (e.g., using antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, antenna 252, controller / processor 280, memory 282, etc.) the beam update command to one or more component carriers at least in part based on the component carriers identified in the beam update command, as described above.

[0084] As Figure 5As shown, in some aspects, process 500 may include: receiving, from a UE, information indicating the UE's ability to support simultaneous beam updates across multiple component carriers (block 510). For example, a base station may receive, from the UE (e.g., using antenna 234, demodulator 232, MIMO detector 236, receive processor 238, controller / processor 240, etc.), information indicating the UE's ability to support simultaneous beam updates across multiple component carriers, as described above.
