Operational rules for group component carrier beam updates

Abstract

A method, apparatus, and computer program product for wireless communication are provided. A user equipment (UE) may receive a signaling message that configures one or more component carrier groups for a joint transmission configuration indication (TCI) state activation. When a beam update command indicates an updated TCI state for an individual component carrier, the UE may apply the beam update command after an action time based at least in part on a format of the beam update command. In addition, if the individual component carrier is not included in any component carrier group and / or multiple beam update commands are received within a threshold time, the UE may be configured with rules for applying the beam update command. In addition, the UE may prioritize quasi-co-location (QCL) reception of all component carriers associated with the same TCI state as another component carrier for which QCL reception is prioritized.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 929,725, filed on November 1, 2019, entitled “OPERATION RULES FOR GROUP COMPONENT CARRIER BEAM UPDATE,” and U.S. Non-Provisional Patent Application No. 16 / 949,396, filed on October 28, 2020, entitled OPERATION RULES FOR GROUP COMPONENT CARRIER BEAM UPDATE, which are expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for configuring operating rules for component carrier beam updates. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies, which may be capable of supporting communications with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and / or other). Examples of such multiple access technologies include code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), time division synchronous code division multiple access (TD-SCDMA), and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) that can support communications for multiple user equipment (UEs). User equipment (UEs) can communicate with a base station (BS) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an 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), 5G Bs, 5G Node B, etc.

[0006] To provide a universal protocol that enables diverse wireless communication devices to communicate at city, national, regional, and even global levels, these multiple access technologies are being adopted in various telecommunications standards. 5G, also known as New Radio (NR), is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). 5G aims to better support mobile broadband internet access by increasing spectral efficiency, reducing costs, improving services, utilizing new spectrum, using OFDM with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), supporting beamforming, multiple-input, multiple-output (MIMO) antenna technology, and carrier aggregation, and better integrating with other open standards. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies, as well as the telecommunications standards that employ them, remain valuable. Summary of the Invention

[0007] In some communication systems (such as 5G), the bandwidth can be divided into multiple bandwidth parts and / or multiple component carriers. Each bandwidth part and / or component carrier can use parameters that may be specific to the bandwidth part and / or component carrier to implement uplink and / or downlink communication between a user equipment (UE) and a base station (BS). For example, the UE can communicate with the BS on a first bandwidth part according to a first communication configuration, and can communicate with the BS on a second bandwidth part according to a second communication configuration. This can achieve flexibility in terms of UE deployment, power saving configuration, etc. relative to a single communication configuration for the entire bandwidth.

[0008] The BS may send a medium access control (MAC) control element (CE) to activate a transmission configuration indicator (TCI) state set (e.g., associated with a TCI state identifier set) for a physical downlink shared channel (PDSCH). The UE may apply the TCI state set to a set of bandwidth portions and / or component carriers within a common frequency band and / or sharing a common analog beamformer. The UE may receive signaling from the BS indicating component carriers among a plurality of candidate component carriers within the bandwidth to which the UE will apply the TCI state set. For example, the BS may provide radio resource control (RRC) signaling indicating the set of component carriers and / or the set of bandwidth portions corresponding to the set of component carriers, and the UE may group the set of component carriers based on the RRC signaling. In this manner, when the UE receives signaling (e.g., MAC-CE) to activate the TCI state set, the UE may apply subsequent signaling to the component carrier group rather than to all component carriers of the plurality of candidate component carriers. In some cases, the UE may be configured with multiple component carrier groups. In this case, when the UE receives signaling for activating a TCI state set for a specific component carrier, the UE may apply the signaling to each component carrier within the component carrier group including the specific component carrier.

[0009] Thus, by providing signaling that enables a UE to activate a TCI state set for each component carrier in a component carrier group that includes a particular component carrier, signaling overhead can be reduced relative to a system in which signaling is used to activate TCI state sets for individual component carriers, bandwidth parts, etc. Furthermore, providing group-based signaling to enable joint activation of TCI state sets for all component carriers, bandwidth parts, etc. in a particular component carrier group can enable greater flexibility in carrier aggregation scenarios, in which the UE and the base station communicate simultaneously over multiple carriers. However, the UE may need to determine: how to apply the signaling in the event that a particular component carrier identified in the signaling is not included in any component carrier group configured for the UE, when the signaling will take effect, how to resolve the situation in which the UE receives multiple signaling messages for updating the TCI state for the component carrier group, how to prioritize reception of different component carriers, etc.

[0010] Certain aspects described herein provide various operating rules for updating beam information of component carrier groups. For example, a UE may receive signaling (e.g., RRC signaling) from a BS to configure one or more component carrier groups, and the UE may receive subsequent signaling (e.g., MAC-CE) including a beam update command, which identifies individual component carriers and one or more TCI states to be applied to the individual component carriers. In general, as described above, the UE may apply the one or more TCI states indicated in the beam update command to each component carrier in the same component carrier group as the individual component carrier identified in the beam update command and to each bandwidth portion within such a component carrier. However, in some cases, the beam update command may indicate an updated TCI state for an individual component carrier that is not included in any component carrier group. In this case, the UE may apply the beam update command to the individual component carrier identified in the beam update command. Additionally or alternatively, the UE may form an implicit component carrier group that includes all configured component carriers that are not in the (multiple) component carrier groups configured by the BS, and the UE may apply the beam update command to all component carriers in the implicit component carrier group. Furthermore, in some cases, the UE may determine an action time when to apply a beam update command (e.g., implicitly based on the time when the component carrier group is configured, explicitly based on signaling provided by the BS, etc.). Additionally, in certain aspects, the UE may apply one or more rules to resolve multiple beam update commands received simultaneously or within a threshold time of each other, and / or prioritize quasi-co-location (QCL) reception of a component carrier that is associated with the same TCI state as another component carrier for which QCL reception is prioritized.

[0035] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent configurations in which the concepts described herein may be practiced. The detailed description includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0036] Several aspects of telecommunication systems will now be presented with reference to various apparatuses and methods. These apparatuses and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and design constraints imposed on the overall system.

[0037] As an example, any part of an element or an element or any combination of elements can be implemented with a "processing system" comprising one or more processors. The example of a processor includes a microprocessor, a microcontroller, a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic device (PLD), a state machine, a gated logic, a discrete hardware circuit, and other suitable hardware configured to perform the various functions described in the present disclosure. One or more processors in the processing system can run software. Whether referred to as software, firmware, middleware, microcode, hardware description language or other forms, software should be broadly interpreted as meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions and / or the like.

[0038] Therefore, in one or more example embodiments, the functions described can be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the function can be stored as one or more instructions or codes on a computer-readable medium or encoded on a computer-readable medium. Computer-readable media include computer storage media. The storage medium can be any available medium that a computer can access. As an example and not limitation, such a computer-readable storage medium can include a random access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), a compact disc ROM (CD-ROM) or other optical disc storage, a magnetic disk storage or other magnetic storage device, a combination of the aforementioned types of computer-readable media, or any other medium that can be used to store computer-executable code in the form of instructions or data structures that a computer can access.

[0039] It should be noted that although terminology generally associated with 5G radio access technology (RAT) may be used herein to describe various aspects, various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G)).

[0040] Figure 1is a diagram illustrating an example of a wireless network 100 in which aspects of the present disclosure may be practiced. The wireless network 100 may be or may include elements of a 5G (NR) network, an LTE network, or the like. The wireless network 100 may include multiple 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 a user equipment (UE) and may also be referred to as a 5G BS, Node B, gNB, 5G NB, access point, transmit receive point (TRP), or the like. Each BS may provide communication coverage to a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of a BS and / or a BS subsystem serving that coverage area, depending on the context in which the term is used.

[0041] A BS may provide communication coverage to 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., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to 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 In the example shown, BS 110a may be a macro BS for macrocell 102a, BS 110b may be a pico BS for picocell 102b, and BS 110c may be a femto BS for femtocell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB," "base station," "5G BS," "gNB," "TRP," "AP," "Node B," "5G NB," and "cell" may be used interchangeably herein.

[0042] In some examples, the cells may not necessarily be fixed, and the geographic area of the cells may move depending on the location of the mobile BS. In some examples, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in wireless network 100 via various types of backhaul interfaces (such as direct physical connections, virtual networks, and / or using any suitable transport network).

[0043] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit the data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions of other UEs. Figure 1 In the example shown, relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, etc.

[0044] The wireless network 100 may be a heterogeneous network including different types of BSs, such as 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 higher transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0045] A 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, for example, via a wireless or wired backhaul.

[0046] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), 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 computer, a camera, a gaming device, a netbook, a smart notebook, an ultrabook, a medical device or apparatus, a biosensor / device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband), smart jewelry (e.g., a smart ring, a smart bracelet), an entertainment device (e.g., a music or video device or satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0047] Some UEs may be considered 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 may communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide connectivity to or to 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 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component, a memory component, etc.).

[0048] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, 5G RAT networks can be deployed. Some RATs can be divided into component carriers and / or associated bandwidth portions, such as in a carrier aggregation deployment. In this case, the BS can group a set of component carriers into component carrier groups and can send signaling to configure one or more component carrier groups for joint transmission configuration indication (TCI) state activation. When a beam update command indicates an updated TCI state for an individual component carrier, the UE can apply the beam update command after an action time based at least in part on the format of the beam update command. In addition, if the individual component carrier is not included in any component carrier group and / or multiple beam update commands are received within a threshold time, the UE can be configured with rules for applying the beam update command. Additionally, the UE may prioritize quasi co-location (QCL) reception for all component carriers that are associated with the same TCI state as another component carrier for which QCL reception is prioritized.

[0049] In some examples, access to the air interface can be scheduled, where a scheduling entity (e.g., a base station) allocates resources for communication between some or all devices and equipment within a service area or cell of the scheduling entity. Within the present disclosure, as further described below, the scheduling entity can be responsible for scheduling, allocating, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, the subordinate entities can utilize the resources allocated by the scheduling entity.

[0050] The base station is not the only entity that can act as a scheduling entity. That is, in some examples, a UE can act as a scheduling entity, scheduling resources for one or more subordinate entities (e.g., one or more other UEs). In this example, the UE acts as the scheduling entity, and other UEs communicate wirelessly using the resources scheduled by the UE. The UE can act as a scheduling entity in a peer-to-peer (P2P) network and / or a mesh network. In the mesh network example, in addition to communicating with the scheduling entity, the UEs can also optionally communicate directly with each other.

[0051] Therefore, in a wireless communication network having scheduled access to time-frequency resources and having a cellular configuration, a P2P configuration, and a mesh configuration, a scheduling entity and one or more subordinate entities may communicate using the scheduled resources.

[0052] Devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1), wherein the first frequency range can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2), wherein the second frequency range can 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 often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless otherwise expressly stated, it should be understood that the terms "sub-6 GHz," etc., if used herein, can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise expressly stated, it should be understood that the terms "millimeter wave," etc., if used herein, can broadly refer to 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 are applicable to those modified frequency ranges.

[0053] As mentioned above, Figure 1 Provided as examples only. Other examples may differ from those on Figure 1 The examples described are different.

[0054] Figure 2is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100. The base station 110 may be equipped with T strip antennas 234a through 234t, and the UE 120 may be equipped with R strip antennas 252a through 252r, where in general T≥1 and R≥1.

[0055] At the base station 110, a transmit processor 220 may receive data for one or more UEs from a data source 212, may select a modulation and coding scheme (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, may process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and may provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI) 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 signals (CRS), demodulation reference signals (DMRS), etc.) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on 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 a 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 (e.g., an RRC signal to configure one or more component carrier sets, a MAC-CE to indicate a beam update command, etc.). The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0056] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, 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. A 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 detected symbols. A receive (RX) processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information (e.g., information related to one or more component carrier sets, one or more beam update commands, etc.) to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. A 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 a housing 284.

[0057] In certain aspects, the controller / processor 280 may apply one or more rules to determine how to apply one or more beam update commands. For example, the UE may apply a beam update command after an action time based at least in part on the format of the beam update command. Furthermore, if an individual component carrier is not included in any component carrier group and / or multiple beam update commands are received within a threshold time, the UE may be configured with rules for applying the beam update command. Additionally, the UE may prioritize QCL reception for all component carriers associated with the same TCI state as another component carrier for which QCL reception is prioritized.

[0058] 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.

[0059] On the uplink, at the UE 120, a transmit processor 264 may receive and process data and control information (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.) from a data source 262 from a controller / processor 280. 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 by a 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. In certain aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, a modulator and / or demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280 ) and memory 282 to perform aspects of any of the methods described herein.

[0060] At base station 110, uplink signals from UE 120 and other UEs may be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include a communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UE 120 for downlink and / or uplink communications. In certain aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (eg, controller / processor 240 ) and memory 242 to perform aspects of any of the methods described herein.

[0061] As described in more detail elsewhere herein, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with updated beam information associated with the component carrier group. Figure 2 Any other component of the may perform or direct e.g. Figure 4Method 400, Figure 5 Method 500, Figure 6 Method 600, Figure 7 Method 700, and / or other processes described herein. Memories 242 and 282 may store data and program codes for BS 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium for storing one or more instructions for wireless communications. For example, the one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, conversion, interpretation, and / or the like), may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 4 The process of 400 Figure 5 The process of 500 Figure 6 The process of 600 Figure 7 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, interpreting instructions, etc.

[0062] As mentioned above, Figure 2 Provided as examples only. Other examples may differ from those on Figure 2 The examples described are different.

[0063] 5G may refer to a radio configured to operate according to a new air interface (e.g., other than an air interface based on Orthogonal Frequency Division Multiple Access (OFDMA)) or a fixed transport layer (e.g., other than Internet Protocol (IP)). In certain aspects, 5G may utilize OFDM with CP (referred to herein as cyclic prefix OFDM or CP-OFDM) and / or SC-FDM on the uplink, may utilize CP-OFDM on the downlink, and include support for half-duplex operation using TDD. In certain aspects, 5G may utilize, for example, OFDM with CP (referred to herein as CP-OFDM) and / or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) on the uplink, may utilize CP-OFDM on the downlink, and include support for half-duplex operation using TDD. 5G may include enhanced mobile broadband (eMBB) services for wide bandwidth (e.g., 80 megahertz (MHz) and above), millimeter wave (mmW) for high carrier frequencies (e.g., 60 gigahertz (GHz)), massive MTC (mMTC) for non-backward compatible MTC technologies, and / or mission critical ultra-reliable low latency communication (URLLC) services.

[0064] A single component carrier bandwidth of 100 MHz can be supported. A 5G resource block can span 12 subcarriers with a subcarrier bandwidth of 75 kilohertz (kHz) and a duration of 0.1 millisecond. Each radio frame can include 50 subframes of length 10 ms. Therefore, each subframe can have a length of 0.2 ms. Each subframe can indicate the link direction (e.g., DL or UL) used for data transmission, and the link direction of each subframe can be switched dynamically. Each subframe can include DL / UL data and DL / UL control data.

[0065] Beamforming can be supported, and the beam direction can be dynamically configured. MIMO transmission with precoding can also be supported. MIMO configurations in the DL can support up to 8 transmit antennas, multi-layer DL transmission up to 8 streams, and up to 2 streams per UE. Aggregation of multiple cells up to 8 serving cells can be supported. Alternatively, 5G can support a different air interface instead of an OFDM-based interface. 5G networks can include entities such as a central unit or distributed units.

[0066] The RAN may include a central unit (CU) and a distributed unit (DU). A 5G BS (e.g., gNB, 5G Node B, Node B, transmit receive point (TRP), access point (AP)) may correspond to one or more BSs. A 5G cell may be configured as an access cell (ACell) or a data-only cell (DCell). For example, the RAN (e.g., a central unit or a distributed unit) may configure a cell. A DCell may be a cell used for carrier aggregation or dual connectivity, but not for initial access, cell selection / reselection, or handover. In some aspects, a DCell may not send a synchronization signal. In some aspects, a DCell may send a synchronization signal. The 5G BS may send a downlink signal to the UE indicating the cell type. Based at least in part on the cell type indication, the UE may communicate with the 5G BS. For example, the UE may determine, based at least in part on the indicated cell type, a 5G BS to be considered for cell selection, access, handover, and / or measurement.

[0067] Figure 3 FIG. 1 is a diagram illustrating one or more examples 300 of using operating rules to update beam information associated with one or more component carriers. Figure 3As shown, example 300 may include a UE 305 and a BS 310 communicating using carrier aggregation. For example, in some aspects, carrier aggregation may generally enable two or more component carriers (CCs, sometimes referred to as carriers) to be combined (e.g., into a single channel) for a single UE to enhance data capacity. In general, component carriers may be combined in the same or different frequency bands, the same or different frequency ranges, etc. Additionally or alternatively, contiguous or non-contiguous component carriers may be combined. In some aspects, BS 310 may configure carrier aggregation for UE 305 in intra-band contiguous mode, where the aggregated component carriers are adjacent to each other and in the same frequency band. Additionally or alternatively, carrier aggregation may be configured in intra-band non-contiguous mode, where the aggregated component carriers are in the same frequency band and non-contiguous with each other. Additionally or alternatively, carrier aggregation may be configured in inter-band non-contiguous mode, where the aggregated component carriers are non-contiguous with each other and in different frequency bands.

[0068] At 320, BS 310 may send and UE 305 may receive signaling for configuring one or more component carrier sets associated with a joint transmission configuration indication (TCI) state activation. In certain aspects, one or more component carrier sets may be indicated in radio resource control (RRC) signaling, and each set may include multiple component carriers, bandwidth portions, etc. for which the TCI state is jointly activated. In certain aspects, where UE 305 is configured with multiple component carrier sets, the multiple component carrier sets may be non-overlapping (e.g., a particular component carrier, bandwidth portion, etc. included in one component carrier set is not included in any other component carrier set). Furthermore, in certain aspects, UE 305 may be associated with one or more serving cells (e.g., a serving cell associated with BS 310, a serving cell TRP associated with BS 310, a serving cell associated with a different BS, etc.), and each component carrier, bandwidth portion, etc. associated with the serving cell(s) for UE 305 may be included in one of the component carrier sets.

[0069] At 330, the UE 305 may prioritize QCL reception for all component carriers that have the same TCI state as the component carrier for which QCL reception is prioritized. For example, because component carriers, bandwidth parts, etc. in a particular component carrier set are grouped together for joint TCI state activation, the grouped component carriers, bandwidth parts, etc. may generally have the same TCI state. Thus, for QCL prioritization across different channels, reference signals, etc. that are simultaneously received on different component carriers, bandwidth parts, etc., when group-based beam updating is enabled, the UE 305 may assume that QCL information corresponding to a particular TCI state identifier is the same for all component carriers, bandwidth parts, etc. that share the particular TCI state identifier. Thus, where one or more rules prioritize reception of QCL information associated with a given component carrier (e.g., the component carrier with the lowest identifier, lowest frequency, etc.), the UE 305 may prioritize QCL information associated with all other component carriers that have the same TCI state identifier as the given component carrier associated with prioritized QCL reception. In this way, when one or more spatial reception parameters (e.g., QCL type D parameters) are prioritized for one component carrier associated with a given TCI state identifier, UE 305 can assume that all other component carriers and bandwidth parts associated with the same TCI state identifier have the same spatial reception parameters and, therefore, can also be prioritized. In this way, the one or more component carrier sets configured by BS 310 can group component carriers, bandwidth parts, etc. for which QCL reception is to be prioritized.

[0070] Furthermore, in certain aspects, similar principles can be used when the UE 305 performs beam failure detection. For example, when the UE 305 performs beam failure detection for one component carrier, bandwidth portion, etc. in a particular component carrier set, the result of the beam failure detection can be applied to all component carriers, bandwidth portions, etc. in the particular component carrier set. For example, if the UE 305 determines that one component carrier, bandwidth portion, etc. in the component carrier set has signal loss, blocking, and / or similar failures, the UE 305 can determine that all other component carriers, bandwidth portions, etc. in the same component carrier set also have signal loss, blocking, and / or similar failures because all component carriers, bandwidth portions, etc. in the component carrier set are associated with the same set of TCI state identifiers.

[0071] At 340, the BS 310 may send, and the UE 305 may receive, one or more beam update commands that identify individual component carriers and TCI states to be activated for the individual component carriers. For example, in certain aspects, each of the one or more beam update commands may be included in a medium access control (MAC) control element (MAC-CE). In certain aspects, the one or more beam update commands may be formatted according to a first format for updating TCI state information for individual component carriers, bandwidth parts, etc. Additionally or alternatively, the one or more beam update commands may be formatted according to a second format associated with joint TCI state activation. In either case, the beam update command(s) may identify individual component carriers and / or bandwidth parts and a set of one or more TCI states to be activated for the individual component carriers and / or bandwidth parts, and the UE 305 may determine how to apply the beam update command(s) based at least in part on the set of component carriers configured by the BS 310.

[0072] At 350, the UE 305 may apply the beam update command based at least in part on the individual component carrier identified in the beam update command. For example, in certain aspects, the UE may identify a component carrier set that includes the individual component carrier identified in the beam update command, and apply one or more TCI states indicated in the beam update command to each component carrier in the same component carrier set as the component carrier identified in the beam update command and to each bandwidth part associated with such component carrier. For example, in certain aspects, each serving cell configured for the UE 305 may be included in at least one component carrier set (e.g., using a simultaneousTCI-UpdateList1-r16 parameter, a simultaneousTCI-UpdateList2-r16 parameter, a simultaneousSpatial-UpdatedList1-r16 parameter, a simultaneousSpatial-UpdatedList2-r16 parameter, or another suitable parameter), and the UE 305 may apply the beam update command received from the base station to all serving cells in the same component carrier set as the individual component carrier identified in the beam update command.

[0073] However, in some cases, the individual component carriers indicated in the beam update command may not be included in any component carrier set configured by BS 310. Therefore, in such cases, UE 305 may apply one or more rules to determine how to apply the beam update command. For example, in some aspects, UE 305 may apply the beam update command according to conventional behavior, which may include applying the beam update command only to the individual component carriers indicated in the beam update command. Alternatively, in some aspects, UE 305 may configure an implicit component carrier set that includes any component carriers, bandwidth parts, etc. that are not included in any component carrier set configured by BS 310, and UE 305 may apply the beam update command to all component carriers, bandwidth parts, etc. in the implicit component carrier set. Thus, in the event that the individual component carrier indicated in the beam update command is not included in any component carrier set configured by BS 310, UE 305 may apply the beam update command to at least the individual component carrier indicated in the beam update command, and in some cases, UE 305 may also apply the beam update command to any other component carrier, bandwidth portion, etc. that is not included in any component carrier set configured by BS 310.

[0074] In certain aspects, the UE 305 may determine an action time after which the beam update command is ready for use or otherwise allowed to take effect. For example, based at least in part on the signaling used to configure the one or more component carrier sets, the UE 305 may send and the BS 310 may receive an RRC reconfiguration complete message to confirm or otherwise indicate that the one or more component carrier sets have been configured, reconfigured, etc. at the UE 305. In certain aspects, based at least in part on the RRC reconfiguration complete message, the BS 310 may then send and the UE 305 may receive an acknowledgment message. In certain aspects, the acknowledgment message may be used as an implicit indicator of an action time after which the group-based beam update command provided to the UE 305 is allowed to take effect. Additionally or alternatively, the BS 310 may explicitly indicate an action time after which the group-based beam update command is allowed to take effect (e.g., via a MAC-CE, downlink control information (DCI), etc.). In certain aspects, whether the action time is implicitly indicated by the ACK of the reconfiguration complete message or explicitly indicated by the BS 310 may generally depend on the format of the group-based beam updating command. For example, if the group-based beam updating command is formatted for individual TCI state activation, the action time after which the group-based beam updating command can be applied may correspond to the time of receipt of the ACK of the reconfiguration complete message. Alternatively, if the group-based beam updating command is formatted for joint TCI state activation, the action time may correspond to the time of receipt of the ACK of the reconfiguration complete message or an explicit indicator provided by the BS 310 via downlink signaling (e.g., MAC-CE, DCI, etc.) indicating that the beam updating command is ready to be applied.

[0075] In some cases, the UE 305 may receive multiple beam update commands within a threshold time of each other. For example, the UE 305 may receive a first beam update command and a second beam update command simultaneously within a short time of each other (e.g., within a few milliseconds of each other) (e.g., on different component carriers in the same component carrier set), etc. Therefore, when the UE 305 receives multiple beam update commands and the reception time difference between the multiple beam update commands meets a threshold (e.g., when the reception time difference is zero in the case of simultaneous reception, is less than and / or equal to the threshold, etc.), the UE 305 may apply one or more rules to select a specific beam update command to apply. For example, in some aspects, the UE 305 may select a specific beam update command to apply based on the arrival time of the multiple beam update commands. For example, the UE 305 may select one of the multiple beam update commands with the latest arrival time, the earliest arrival time, etc. Additionally or alternatively, in some aspects, the UE 305 may select a specific beam update command to apply based on information associated with the component carriers identified in the multiple beam update commands. For example, the UE 305 may select one of multiple beam update commands that identifies the component carrier with the highest index, the lowest index, etc. Additionally or alternatively, in certain aspects, the UE 305 may be configured with another suitable rule that defines which beam update command to apply when multiple beam update commands are received simultaneously within a threshold time, etc.

[0076] As mentioned above, Figure 3 are provided as examples. Other examples may be related to Figure 3 The examples described are different.

[0077] Figure 4 4 is a flow chart of a wireless communication method 400. The method 400 may be performed by a UE (eg, UE 120, UE 305, apparatus 802 / 802', etc.).

[0078] At 410, the UE may receive a signaling message indicating one or more indicated component carrier sets. For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive RRC signaling indicating one or more indicated component carrier sets, each of which may include a component carrier group associated with a joint TCI state activation, as described in more detail above. In a first aspect, the UE is associated with one or more serving cells, and each of the one or more serving cells is associated with a component carrier that is included in a component carrier group associated with one of the one or more indicated component carrier sets.

[0079] At 420, the UE may receive a beam update command that identifies the individual component carrier and the TCI state to be activated for the individual component carrier (block 420). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive a MAC-CE that includes a beam update command that identifies the individual component carrier and the TCI state to be activated for the individual component carrier, as described in more detail above. In certain aspects, the individual component carrier identified in the beam update command is not included in the one or more indicated component carrier sets.

[0080] At 430, the UE may apply the beam update command to a set of component carriers that includes at least the individual component carrier identified in the beam update command. For example, the UE (e.g., using the controller / processor 280, the memory 282, etc.) may apply the beam update command to a set of one or more component carriers that includes at least the individual component carrier identified in the beam update command, as described in more detail above. In certain aspects, the individual component carrier is included in the set of one or more component carriers based at least in part on the individual component carrier not being in any of the one or more indicated sets of component carriers. In a second aspect, alone or in combination with the first aspect, the set of one or more component carriers to which the beam update command is applied includes only the individual component carrier identified in the beam update command. In a third aspect, alone or in combination with one or more of the first and second aspects, the set of one or more component carriers to which the beam update command is applied includes component carriers configured for the UE that are not included in any of the one or more indicated sets of component carriers.

[0081] Method 400 may include additional aspects, such as any single aspect or any combination of aspects described above and / or in combination with one or more other processes described elsewhere herein.

[0082] although Figure 4 An example block diagram of a method of wireless communication is shown, but in some aspects the method may include Figure 4 Additional boxes, fewer boxes, different boxes, or differently arranged boxes compared to those depicted in FIG. Additionally or alternatively, Figure 4 Two or more blocks shown in FIG. 1 may be executed in parallel.

[0083] Figure 5 5 is a flow chart of a method 500 of wireless communication. The method 500 may be performed by a UE (eg, UE 120, UE 305, apparatus 802 / 802', etc.).

[0084] At 510, the UE may receive a signaling message indicating one or more component carrier sets. For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive RRC signaling indicating one or more component carrier sets, each of which may include a component carrier group associated with a joint TCI state activation, as described in more detail above. In a first aspect, the UE is associated with one or more serving cells, and each of the one or more serving cells is associated with a component carrier included in a component carrier group associated with one of the one or more component carrier sets.

[0085] At 520, the UE may receive a beam update command identifying a component carrier and a TCI state to be activated for the component carrier. For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive a beam update command identifying a component carrier and a TCI state to be activated for the component carrier, as described in more detail above. In certain aspects, the component carrier identified in the beam update command is included in a component carrier group associated with one of the one or more component carrier sets.

[0086] At 530, after an action time based at least in part on whether the beam update command is formatted for individual TCI state activation or joint TCI state activation, the UE may apply the beam update command to the component carrier group including the component carrier identified in the beam update command. For example, after an action time based at least in part on whether the beam update command is formatted for individual TCI state activation or joint TCI state activation, the UE (using the controller / processor 280, the memory 282, etc.) may apply the beam update command to the component carrier group including the component carrier identified in the beam update command, as described in more detail above. In a first aspect, the UE may send a reconfiguration complete message to the BS based at least in part on a signaling message indicating one or more component carrier sets, the UE may receive an acknowledgment message from the BS based at least in part on the reconfiguration complete message, and based at least in part on whether the beam update command is formatted for individual TCI state activation, the action time being the time of receipt of the acknowledgment message. In a second aspect, alone or in combination with the first aspect, the UE may receive an indication from the BS that a beam update command is ready to be applied (e.g., via MAC-CE, DCI, etc.), and based at least in part on the beam update command being formatted for joint TCI state activation, the action time is the time of receipt of the indication.

[0087] Method 500 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0088] although Figure 5 Example blocks of method 500 are shown, but in some aspects, method 500 may include Figure 5 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the method 500. Additionally or alternatively, two or more blocks of the method 500 may be executed in parallel.

[0089] Figure 6 6 is a flow chart of a method 600 of wireless communication. The method 600 may be performed by a UE (eg, UE 120, UE 305, apparatus 802 / 802', etc.).

[0090] At 610, the UE may receive a first beam update command identifying a first TCI state to be activated. For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive the first beam update command identifying a first TCI state to be activated, as described in more detail above.

[0091] At 620, the UE may receive a second beam update command identifying a second TCI state to be activated. For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive the second beam update command identifying a second TCI state to be activated, as described in more detail above. In a first aspect, the first beam update command and the second beam update command are included in a MAC-CE.

[0092] At 630, the UE may select a beam update command corresponding to the first beam update command or the second beam update command based at least in part on reception times associated with the first beam update command and the second beam update command. For example, the UE (e.g., using the controller / processor 280, the memory 282, etc.) may select the beam update command corresponding to the first beam update command or the second beam update command based at least in part on a difference in reception times between the first beam update command and the second beam update command satisfying a threshold, as described in more detail above. In a second aspect, alone or in combination with the first aspect, the selected beam update command corresponds to one of the first beam update command or the second beam update command having the latest arrival time. In a third aspect, alone or in combination with one or more of the first and second aspects, the selected beam update command corresponds to one of the first beam update command or the second beam update command having the earliest arrival time. In a fourth aspect, alone or in combination with one or more of the first to third aspects, the selected beam update command corresponds to one of the first beam update command or the second beam update command that identifies the component carrier with the lowest index. In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the selected beam update command corresponds to one of a first beam update command or a second beam update command identifying a component carrier with a highest index. In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, the selected beam update command is based at least in part on a configuration rule associated with the UE.

[0093] At 640, the UE may apply the selected beam update command to the component carrier group including the component carrier identified in the selected beam update command. For example, the UE (e.g., using the controller / processor 280, the memory 282, etc.) may apply the selected beam update command to the component carrier group including the component carrier identified in the selected beam update command, as described in more detail above. In certain aspects, applying the selected beam update command includes activating a first TCI state or a second TCI state for each component carrier in the component carrier group, depending on whether the beam update command corresponds to a first beam update command or a second beam update command.

[0094] Method 600 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0095] although Figure 6 Example blocks of method 600 are shown, but in some aspects, method 600 may include Figure 6Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in method 600. Additionally or alternatively, two or more blocks of method 600 may be executed in parallel.

[0096] Figure 7 7 is a flow chart of a wireless communication method 700. The method 700 may be performed by a UE (eg, UE 120, UE 305, apparatus 802 / 802', etc.).

[0097] At 710, the UE may receive a message enabling joint TCI state activation for multiple component carriers in a component carrier group. For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive a message enabling joint TCI state activation for multiple component carriers in a component carrier group, as described in more detail above. In some aspects, the multiple component carriers in the component carrier group are associated with a common TCI state identifier.

[0098] At 720, the UE may prioritize reception of QCL information associated with each of the plurality of component carriers associated with the common TCI state identifier. For example, the UE (e.g., using the controller / processor 280, the memory 282, etc.) may prioritize reception of QCL information associated with each of the plurality of component carriers associated with the common TCI state identifier based at least in part on one or more rules for prioritizing QCL information associated with at least one of the plurality of component carriers in the component carrier group.

[0099] Method 700 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0100] although Figure 7 Example blocks of method 700 are shown, but in some aspects, method 700 may include Figure 7 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in method 700. Additionally or alternatively, two or more blocks of method 700 may be executed in parallel.

[0101] Figure 8 is a conceptual data flow diagram 800 illustrating the data flow between different modules / parts / components in an example apparatus 802. The apparatus 802 may be a UE in communication with a BS 850. In certain aspects, the apparatus 802 includes a receiving module 804, a prioritizing module 806, a sending module 808, a selecting module 810, an applying module 812, and the like.

[0102] The receiving module 804 may receive one or more signaling messages as data 820 from the BS 850. For example, the receiving module 804 may receive RRC signaling configuring one or more component carrier sets for joint TCI state activation from the BS 850. Additionally or alternatively, the receiving module 804 may receive a MAC-CE from the BS 850, the MAC-CE including a beam update command identifying the component carriers and the TCI state to be activated for the component carriers.

[0103] The prioritization module 806 may receive information regarding one or more component carrier sets configured for joint TCI state activation as data 822 from the reception module 804. The prioritization module 806 may prioritize QCL reception for all component carriers having the same TCI state as the component carrier for which QCL reception is prioritized. Thus, for QCL prioritization of different channels, reference signals, etc. that are simultaneously received across different component carriers, bandwidth parts, etc., when the data 822 received from the reception module 804 indicates that group-based beam updating is enabled, the UE 305 may assume that the QCL information corresponding to a particular TCI state identifier is the same for all component carriers, bandwidth parts, etc. that share the particular TCI state identifier.

[0104] The transmitting module 808 may receive information regarding the one or more component carrier sets configured for joint TCI state activation as data 824 from the prioritization module, data 830 from the application module, etc. In certain aspects, the transmitting module 808 may transmit an RRC reconfiguration complete message to confirm the RRC signaling configuring the one or more component carrier sets as data 832 to the BS 850.

[0105] The selection module 810 may receive information regarding one or more component carrier sets configured for joint TCI state activation as data 826 from the reception module 804. In certain aspects, when the data 826 from the reception module indicates that multiple beam update commands are received within a threshold time of each other, the selection module 810 may select a specific beam update command to apply. For example, when the multiple beam update commands are received within a threshold time of each other, the selection module 810 may select one of the multiple beam update commands with the latest arrival time, the earliest arrival time, the component carrier with the highest index, the component carrier with the lowest index, etc., among the multiple beam update commands.

[0106] The application module 812 may receive information related to the beam update command to be applied as data 828 from the selection module 810. For example, the application module 812 may identify a component carrier set that includes the individual component carrier identified in the beam update command to be applied, and apply one or more TCI states indicated in the beam update command to each component carrier in the same component carrier set as the component carrier identified in the beam update command and to each bandwidth part associated with such component carrier. Additionally or alternatively, in the event that the individual component carrier indicated in the beam update command is not included in any component carrier set configured by the BS 850, the application module 812 may apply the beam update command according to one or more rules. For example, in certain aspects, the application module 812 may apply the beam update command only to the individual component carrier indicated in the beam update command, or the application module 812 may apply the beam update command to all component carriers in an implicit component carrier set, the implicit component carrier set including any component carrier, bandwidth part, etc. that is not included in any component carrier set configured by the BS 850.

[0107] The device 802 may include executing the above Figure 4 Method 400, Figure 5 Method 500, Figure 6 Method 600, Figure 7 The method 700 and the like are additional modules for each block of the algorithm. Figure 4 Method 400, Figure 5 Method 500, Figure 6 Method 600, Figure 7 Each block in the method 700 and the like may be performed by a module, and the apparatus may include one or more of these modules.
