[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 814,621, filed on March 6, 2019, entitled “GROUP-BASED BEAM INDICATION AND SIGNALING,” and U.S. Non-Provisional Patent Application No. 16 / 802,021, filed on February 26, 2020, entitled “GROUP-BASED BEAM INDICATION AND SIGNALING,” which are hereby expressly incorporated herein by reference. Technical Field

[0004] Various aspects of the technology described below generally relate to wireless communications, and more particularly to technologies and apparatuses for group-based beam indication and signaling. Some of the technologies and apparatus described herein enable and provide wireless communication devices and systems configured to reduce network resource overhead, increase signaling flexibility, and / or conserve energy resources.

[0005] introduction

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support 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 / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0007] A wireless communication network may include several base stations (BS) that can support communication of several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. Downlinks (or forward links) refer to the communication link from a BS to a UE, while uplinks (or reverse links) refer to the communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receive Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at a city, country, region, and even global level. New Radio (NR), which may also be referred to as 5G, is an enhancement set to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). As the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. These improvements may be applicable to other multiple access technologies and telecommunication standards that employ these technologies.

[0014] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, may cause the one or more processors to: receive a beam indication (e.g., for a downlink beam and / or for an uplink beam) for at least one of a channel, a resource, a resource set, a bandwidth portion, or a component carrier; and use the beam indication for a group of channels, resources, resource sets, bandwidth portions, or component carriers.

[0027] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method.

[0028] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements" or "features"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0029] Although some aspects may be described herein using terminology generally associated with 3G and / or 4G wireless technologies, aspects of the disclosure may be applicable to communication systems based on other generations, such as 5G and later generations, including NR technologies.

[0030] Although various aspects and embodiments are described in this application by explanation of some examples, it will be understood by those skilled in the art that additional implementations and use cases can be generated in many different arrangements and scenarios. The innovation described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, each embodiment and / or use can be generated via an integrated chip embodiment and / or other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / purchase equipment, medical equipment, AI-enabled devices, etc.). Although some examples may or may not be specifically for each use case or application, the wide applicability of the described innovation may occur. The scope of each implementation can range from chip-level or module components to non-module, non-chip-level implementations, and further to aggregated, distributed or OEM devices or systems incorporating one or more aspects of the described innovation. In some practical environments, the equipment incorporating the various aspects and features described may also necessarily include additional components and features for implementing and practicing the claimed and described embodiments. For example, the transmission and reception of wireless signals necessarily include several components for analog and digital purposes (e.g., hardware components, including one or more antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The innovations described herein are intended to be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, end-user devices, etc., of various sizes, shapes, and configurations.

[0031] Figure 1 1 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BSs 110a, BSs 110b, BSs 110c, and BSs 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NRBS, B node, gNB, 5G B node (NB), access point, transmit receive point (TRP), and the like. In some deployments, a BS may be referred to as a scheduling entity (e.g., because a BS may schedule communications for other devices). Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0032] A BS may provide communication coverage for areas of varying sizes or ranges. The BS may be configured to enable communications in various cell arrangements, including macro cells, pico cells, femto cells, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) 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 residence) 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 In the example shown in , 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", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0033] In some aspects, a cell may not necessarily be stationary. A mobile cell enables the geographic area of ​​the cell to move according to the location of the mobile BS. In some aspects, a UE may be configured to perform BS functionality. In some aspects, BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections, virtual networks, and / or analogs using any suitable transport networks).

[0034] The wireless network 100 may also include a relay station. 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 the 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. Figure 1 In the example shown in , a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0035] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0036] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0037] UE 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, 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), a vehicle, a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a robot, a drone, an implantable device, an augmented reality device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0038] Some UEs may be considered as machine type communication (MTC) UEs, 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. 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, for example, a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, and the like. In addition, in some deployments, a UE may be referred to as a scheduled entity (e.g., because UE communications may be scheduled by another entity (e.g., a BS or another scheduling entity)).

[0039] In general, any number of wireless networks can be deployed in a given geographic area. That is, multiple wireless networks can exist and can be deployed simultaneously in a given area. Some devices can be multi-mode devices and can be configured to communicate with multiple networks. In some deployments, the device can operate with only one network, with only a limited number of networks, and / or with only a specific type of network (e.g., 5G stand-alone devices). 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, NR or 5G RAT networks can be deployed.

[0040] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using 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, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0041] As indicated above, Figure 1 These are provided as examples only. Other examples may differ from those described herein. Figure 1 The content described.

[0042] Figure 2 A block diagram of a design 200 of a base station 110 and a UE 120 is shown, which may be Figure 1 One for each base station and one for each UE in the base station 110. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0043] At the base station 110, the transmit processor 220 may perform several functions associated with communication. For example, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part 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 signals (CRS)) 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, where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a respective 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 up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0044] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 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 to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive 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 to a controller / processor 280. 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 UE 120 may be included in a housing.

[0045] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports 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 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. At the base station 110, uplink signals from the UE 120 as well as other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0046] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component(s) of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) may perform or direct e.g. Figure 6 The process of 600 Figure 7 The operations of process 700, and / or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0047] In some aspects, UE 120 may include: means for receiving a downlink beam indication for at least one of a channel, a resource, a resource set, a bandwidth portion, or a component carrier; and means for using the downlink beam indication for a group of channels, resources, resource sets, bandwidth portions, or component carriers; etc. Additionally or alternatively, UE 120 may include: means for receiving an indication of a spatial relationship and a plurality of PUCCH resources to which the spatial relationship is to be applied; and means for transmitting on one or more PUCCH resources of the plurality of PUCCH resources using the spatial relationship; etc. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as antenna 252, DEMOD 254, MOD 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, and the like.

[0048] As indicated above, Figure 2 These are provided as examples only. Other examples may differ from those described herein. Figure 2 The content described.

[0049] Figure 3300 is a diagram illustrating an example of group-based beam indication and signaling according to various aspects of the present disclosure. A beam indication may include signaling from one communication device to another communication device related to information about one or more communication beams. A beam indicator helps a communication device to identify beam types, obtain information about communication beams, and utilize beams for appropriate or correct communication. A beam indicator may be used to distinguish one beam from another. Additionally or alternatively, a beam indicator may be used to signal information about one or more beams during a communication operation. In various deployment alternatives, a beam indicator may be configured as control or data. A beam indicator may be viewed as beam metadata—data or information about one or more specific beams. Signaling of a beam indicator for a specific beam enables and provides granular information about the beam. By enabling one beam indicator to provide indication status for multiple beams, signaling of a beam indicator (e.g., a single indicator) may be applied and shared across multiple resources / channels, resulting in efficient, high-quality communication.

[0050] The beam indicator may be signaled in various ways. For example, in some cases, the beam indication may be signaled separately for different resources, different resource sets, different channels, different bandwidth parts (BWPs), different component carriers (CCs), and the like. The beam indication (or beam indicator) may be used to signal various parameters, including transmission configuration indication (TCI) states, quasi co-location (QCL) relationships, spatial relationships, and the like. For example, for downlink communications, separate TCI state sets (e.g., configured or activated TCI states) may be indicated by the base station 110 for different bandwidth parts. That is, the base station 110 may signal a first TCI state set for a first bandwidth part, may signal a second TCI state set for a second bandwidth part, and so on for each configured bandwidth part. This allows complete flexibility in configuring the TCI states for each bandwidth part.

[0051] In some cases, the same TCI state set may be indicated for different bandwidth parts (e.g., due to similarity of beam characteristics in a cell). In these cases, when the first TCI state set is the same as the second TCI state set, transmitting a first signal indicating the first TCI state set and transmitting a second signal indicating the second TCI state set wastes network resources for carrying signals, wastes base station resources (e.g., processing resources, memory resources, etc.) for generating and transmitting signals, and wastes UE resources (e.g., processing resources, memory resources, etc.) for receiving and processing signals.

[0052] Similarly, for uplink communications, separate sets of spatial relationships (e.g., configured or activated spatial relationships) may be indicated by base station 110 for different physical uplink control channel (PUCCH) resources and / or different sounding reference signal (SRS) resources (collectively referred to as PUCCH / SRS resources). That is, base station 110 may signal a first activated spatial relationship for a first PUCCH / SRS resource, may signal a second activated spatial relationship for a second PUCCH / SRS resource, and so on for each PUCCH / SRS resource. This allows for complete flexibility in configuring spatial relationships for various bandwidth portions, but requires the transmission of separate signals, such as separate media access control (MAC) control elements (CEs) (MAC-CEs), for each PUCCH / SRS resource.

[0053] In some cases, the same activated spatial resource may be indicated for different PUCCH / SRS resources (e.g., when UE 120 has the capability to support only a single active spatial relationship). In these cases, when the first activated spatial relationship is the same as the second activated spatial relationship, transmitting a first signal indicating the first activated spatial relationship and transmitting a second signal indicating the second activated spatial relationship wastes network resources for carrying the signal, base station resources for generating and transmitting the signal, and UE resources for receiving and processing the signal.

[0054] Some techniques and devices described herein enable communication devices to utilize beam indicators across multiple resources and / or channels. For example, some aspects enable base station 110 to transmit and enable UE 120 to receive beam indications applied to parameter groups or logical parameter groups. Parameter groups may include multiple resources, multiple resource sets, channel groups, multiple BWPs, multiple CCs, etc. For example, TCI states may be applied to multiple BWPs and / or multiple CCs, spatial relationships may be applied to multiple PUCCH resources, etc., thereby saving network resources, base station resources, and UE resources, as indicated above. In addition, some techniques and devices described herein allow efficient and flexible signaling to indicate resources, resource sets, channels, BWPs, and / or CCs to which beam indications are to be applied. These techniques and devices can save network resources by limiting the overhead required for such signaling, while allowing flexibility in indicating resources, resource sets, channels, BWPs, and / or CCs to which beam indications are to be applied. Additional details are provided below.

[0055] As in Figure 3In and as shown by reference numeral 310, the base station 110 may transmit and the UE 120 may receive a beam indication. The beam indication may be specifically applied to one or more communication elements, such as one or more of a channel, a resource, a resource set, a bandwidth portion, and / or a component carrier. As shown by reference numeral 320, the UE 120 and the base station 110 may use the beam indication for a group of communication elements. The group of communication elements may include a channel group, multiple resources, multiple resource sets, multiple bandwidth portions, or multiple component carriers. Therefore, according to some specific exemplary aspects, a single beam indication may be applied to multiple (e.g., a group of) communication elements, such as multiple (e.g., a group of) channels, resources, resource sets, bandwidth portions, and / or component carriers. This approach may save overhead compared to signaling separate beam indications for different communication elements (such as different channels, resources, resource sets, bandwidth portions, and / or component carriers). In some aspects, radio resource control (RRC) messages may be used to configure a set of communication elements (such as a set of channels, resources, resource sets, bandwidth portions and / or component carriers), and MAC-CE and / or downlink control information (DCI) may be used to activate one or more communication elements (such as one or more channels, resources, resource sets, bandwidth portions and / or component carriers from the configured set).

[0056] The group-based beam indication may be used for various parameters. In some aspects, the beam indication may indicate that a TCI state, a QCL relationship, and / or a spatial relationship is to be activated for a first channel, a first resource, a first resource set, a first bandwidth part, and / or a first component carrier, and the UE 120 may use the TCI state, the QCL relationship, and / or the spatial relationship for not only the first channel, the first resource, the first resource set, the first bandwidth part, and / or the first component carrier but also the TCI state, the QCL relationship, and / or the spatial relationship for a second channel, a second resource, a second resource set, a second bandwidth part, and / or a second component carrier (e.g., activate, configure, transmit using the TCI state, the QCL relationship, and / or the spatial relationship, etc.). Additionally or alternatively, UE 120 may use the TCI state, the QCL relationship and / or the spatial relationship for one or more other (e.g., a third, fourth, etc.) channels, resources, resource sets, bandwidth parts and / or component carriers (e.g., activate, configure the TCI state, QCL relationship and / or spatial relationship, use the TCI state, QCL relationship and / or spatial relationship for transmission).

[0057] For example, the base station 110 may transmit an indication of one or more beams (e.g., a single beam or multiple beams that may be indicated using TCI states, QCL relationships, spatial relationships, etc.) to be configured and / or activated (e.g., indicated in a configuration in a memory of the UE 120, activated for use by the UE 120, etc.) for the first bandwidth portion, and the UE 120 may configure and / or activate the one or more beams for the first bandwidth portion and one or more other bandwidth portions (e.g., a second bandwidth portion, a third bandwidth portion, etc.). In some aspects, the one or more other bandwidth portions are not identified in the indication of the one or more beams to be configured and / or activated for the first bandwidth portion.

[0058] Additionally or alternatively, base station 110 may transmit an indication of one or more beams to be configured and / or activated for the first CC, and UE 120 may configure and / or activate the one or more beams for the first CC and one or more other CCs (e.g., a second CC, a third CC, etc.). In some aspects, the one or more other CCs are not identified in the indication of the one or more beams to be configured and / or activated for the first CC.

[0059] Additionally or alternatively, the base station 110 may transmit an indication of one or more beams to be configured and / or activated for the first channel, and the UE 120 may configure and / or activate the one or more beams for the first channel and one or more other channels (e.g., a second channel, a third channel, etc.). In some aspects, the one or more other channels are not identified in the indication of the one or more beams to be configured and / or activated for the first channel. The channels may include, for example, a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), etc.

[0060] Additionally or alternatively, the base station 110 may transmit an indication of one or more beams to be configured and / or activated for a first resource set (e.g., a CSI-RS / PUCCH / SRS resource set), and the UE 120 may configure and / or activate the one or more beams for the first resource set and one or more other resource sets (e.g., a second resource set, a third resource set, etc.). In some aspects, the one or more other resource sets are not identified in the indication of the one or more beams to be configured and / or activated for the first resource set. Additionally or alternatively, the base station 110 may transmit an indication of one or more beams to be configured and / or activated for a first resource (e.g., a CSI-RS / PUCCH / SRS resource), and the UE 120 may configure and / or activate the one or more beams for the first resource and one or more other resources (e.g., a second resource, a third resource, etc.). In some aspects, the one or more other resources are not identified in the indication of the one or more beams to be configured and / or activated for the first resource. In some aspects, the first resource and the second resource are in different configured resource sets.

[0061] In some aspects, the base station 110 may transmit an indication of one or more beams to be configured and / or activated for a first element set including two or more of resources, resource sets, channels, BWPs, or CCs, and the UE 120 may configure and / or activate the one or more beams for the first element set and one or more other element sets (e.g., a second element set, a third element set, etc.). In some aspects, the one or more other element sets are not identified in the indication of the one or more beams to be configured and / or activated for the first element set.

[0062] For example, in example 300, the base station 110 indicates a TCI state set to be configured and / or activated for one or more control resource sets (CORESETs) and PDSCHs on a first bandwidth portion (e.g., identified as BWP 1) and a first CC (e.g., identified as CC 1). The indication may identify BWP 1 and CC 1. In some aspects, the indication may not identify a second bandwidth portion (e.g., BWP 2) and may not identify a second CC (e.g., CC 2). However, the UE 120 may use the indicated TCI state set to configure and / or activate one or more TCI states not only for the CORESETs and PDSCHs on the first bandwidth portion and the first CC, but also for the CORESETs and PDSCHs on the second bandwidth portion and the second CC. In this way, network resources may be saved by the aforementioned transmission of an indication of using the TCI state set for the second bandwidth portion and the second CC. In addition, base station resources that would otherwise be used to generate and transmit the indication may be saved, and UE resources that would otherwise be used to receive and process the indication may be saved.

[0063] In some aspects, the base station 110 may indicate a beam indication (e.g., a spatial relationship) to be configured and / or activated for a first sounding reference signal (SRS) resource set on a first BWP (e.g., BWP 1) in a first CC (e.g., CC 1). The indication may identify BWP 1 and CC 1. In some aspects, the indication may not identify a second bandwidth portion (e.g., BWP 2) and may not identify a second CC (e.g., CC 2). However, the UE 120 may use the beam indication for not only a first SRS resource set on a first BWP in the first CC but also a second SRS resource set on a second BWP in a second CC. In this way, network resources, base station resources, and / or UE resources may be saved, as indicated above.

[0064] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described in Figure 3 Examples described.

[0065] Figure 4 is a diagram illustrating another example 400 of group-based beam indication and signaling in accordance with various aspects of the present disclosure.

[0066] As indicated by reference numeral 410, the base station 110 may transmit and the UE 120 may receive an indication of a spatial relationship and a plurality of PUCCH resources to which the spatial relationship is to be applied. The indication may be transmitted and / or received in a signaling message (such as a MAC-CE, etc.). As further shown, in some aspects, the PUCCH resources may be indicated using one or more component types (sometimes referred to herein as PUCCH resource component types). Additionally or alternatively, the signaling message may indicate a format for a component type or a plurality of formats corresponding to a plurality of component types. The format for a component type may be used to interpret a set of bits (e.g., one or more bits) for indicating a component having the component type and / or identifying a PUCCH resource, as described in more detail below.

[0067] As shown in the reference numeral 420, the signaling message may use one or more component identifiers (sometimes referred to as PUCCH resource component identifiers) to indicate multiple PUCCH resources. The component identifier may include, for example, a PUCCH resource identifier (sometimes referred to as a resource identifier), a PUCCH resource set identifier (sometimes referred to as a resource set identifier), a bandwidth part identifier, and / or a component carrier identifier. The signaling message may include a single component identifier or any combination of multiple component identifiers. Similarly, the component type used to identify the PUCCH resource may include a PUCCH resource (e.g., a resource block, a time domain resource, a frequency domain resource, a time domain and frequency domain resource, etc.), a PUCCH resource set (e.g., a resource block set, a time domain resource set, a frequency domain resource set, a time domain and frequency domain resource set, etc.), a BWP and / or a CC.

[0068] In some aspects, a single component identifier for a single component type may be used to identify the multiple PUCCH resources. For example, a signaling message may indicate a single CC identifier, and this may instruct the UE 120 to use the spatial relationship for all PUCCH resources on the CC identified by the CC identifier (e.g., all communications transmitted using the PUCCH resources on the CC). In some aspects, multiple component identifiers may be used to identify the multiple PUCCH resources. For example, a signaling message may indicate a BWP and a CC, and the UE 120 may use the spatial relationship for all PUCCH resources on the BWP and the CC.

[0069] As shown at 430, a format may be used to indicate a component identifier. In some aspects, the format may be fixed and / or pre-specified (e.g., in a wireless telecommunications standard). In some aspects, the format may be relatively static and may be indicated via a radio resource control (RRC) message. In some aspects, the format may be relatively dynamic. In some aspects, the format may be indicated in a signaling message (such as a MAC-CE), such as Figure 4 shown.

[0070] When a first format (e.g., format 1) is used for a component type, a single component identifier may be used in a signaling message to indicate a component having that component type. For example, when the first format is used for a BWP component type, the BWP may be explicitly identified in a signaling message. In example 400, BWP 1 is explicitly indicated in a signaling message using the first format.

[0071] When a second format (e.g., format 2) is used for a component type, a bitmap having bits corresponding to each configured and / or activated component having the component type may be used in a signaling message to indicate a component having the component type. A first value of the bit (e.g., zero) may indicate that a spatial relationship is not used for a component corresponding to the bit, and a second value of the bit (e.g., one) may indicate that a spatial relationship will be used for a component corresponding to the bit. For example, the base station 110 may configure the UE 120 with a first BWP (e.g., BWP 0), a second BWP (e.g., BWP 1), a third BWP (e.g., BWP 2), and a fourth BWP (e.g., BWP 3) (e.g., for a particular CC). In this case, the bitmap 1001 may indicate that a spatial relationship will be used for BWP 0 and BWP 3, while a spatial relationship will not be used for BWP 1 and BWP 2.

[0072] When the third format (e.g., format 3) is used for a component type, a validity indicator indicating whether the spatial relationship will be used for all components with the component type can be used in the signaling message to indicate the component with the component type. For example, a first value (e.g., zero) of the validity indicator for the component type can indicate that the spatial relationship will not be used for all components with the component type (or will not be used for any component with the component type), and a second value (e.g., one) of the validity indicator can indicate that the spatial relationship will be used for all components with the component type. In some aspects, the validity indicator can be an explicit indication included in the signaling message (e.g., using a single bit for a single component type, a bit set corresponding to a component type set, etc.). In some aspects, the validity indicator can be an implicit indication. For example, if the signaling message does not include any component identifier for a component type, this can indicate that the spatial relationship will be applied to all components with the component type. In example 400, if a BWP or BWP set is not explicitly identified in the signaling message, this indicates that the spatial relationship will be applied to all BWPs.

[0073] When the fourth format (e.g., format 4) is used for a component type, an explicit indication of a plurality of components having the component type may be used in a signaling message to indicate a component having the component type. In this case, the signaling message may indicate the number of components having the component type identified in the signaling message, and may also include a corresponding number (e.g., the same number or quantity) of component identifiers to identify the components to which the spatial relationship is to be applied. In example 400, when the fourth format is used for a BWP component type, the signaling message indicates that two BWP components are identified in the signaling message, and the two BWP components are subsequently identified as BWP 0 and BWP 2. By indicating the number of components in the signaling message, UE 120 may be able to correctly interpret the bits in the signaling message.

[0074] As indicated by reference numeral 440, UE 120 may identify PUCCH resources indicated in a signaling message. For example, UE 120 may interpret bits in the signaling message using an indicated format, where the bits indicate components. UE 120 may use the indicated components to identify PUCCH resources to which the spatial relationship indicated in the signaling message is to be applied. In some aspects, a single MAC-CE (e.g., identified using a single logical channel identifier (LCID) that uniquely identifies the MAC-CE) may indicate the spatial relationship, the format to be used to interpret the bits indicating the components, and the components (e.g., using bits interpreted according to the format). The following is combined with Figure 5 Additional details regarding the contents of MAC-CE are described.

[0075] As an example, if the signaling message uses format 1 for CC component type and does not indicate any other component type, the signaling message may include a single CC identifier that identifies the CC. In this case, UE 120 may apply the indicated spatial relationship (e.g., the spatial relationship activated by MAC-CE) to all PUCCH resources on the CC.

[0076] As another example, if the signaling message uses format 1 for resource set component type, uses format 1 for BWP component type, and uses format 1 for CC component type, the signaling message may include a single resource set identifier that identifies the PUCCH resource set, may include a single BWP identifier that identifies the BWP, and may include a single CC identifier that identifies the CC. In this case, UE 120 may apply the indicated spatial relationship to all PUCCH resources in the indicated PUCCH resource set on the indicated BWP and CC.

[0077] As another example, if the signaling message uses format 2 for PUCCH resource component type, format 1 for BWP component type, and format 1 for CC component type, the signaling message may include a bitmap for identifying PUCCH resources, may include a single BWP identifier that identifies the BWP, and may include a single CC identifier that identifies the CC. In this case, UE 120 may apply the indicated spatial relationship to the PUCCH resources indicated in the bitmap and on the indicated BWP and CC. For example, bits with a value of 1 may indicate that the spatial relationship is to be used for the PUCCH resources corresponding to those bits.

[0078] As indicated by reference numeral 450, the UE 120 may use the spatial relationship identified in the signaling message to transmit communication(s) on one or more PUCCH resources included in the plurality of PUCCH resources indicated in the signaling message. Similarly, the base station 110 may use the spatial relationship identified in the signaling message to receive communication(s) on one or more PUCCH resources included in the plurality of PUCCH resources indicated in the signaling message.

[0079] For example, UE 120 may determine that the PUCCH resources on which communications are scheduled and / or to be transmitted are included in the PUCCH resources indicated in the signaling message. Based at least in part on the determination, UE 120 may transmit communications on the PUCCH resources using the spatial relationship indicated in the signaling message. In this way, the spatial relationship may be flexibly configured while saving network resources, base station resources, and / or UE resources, as described elsewhere herein.

[0080] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described in Figure 4 Examples described.

[0081] Figure 5 is a diagram illustrating an example 500 of group-based beam indication and signaling in accordance with various aspects of the present disclosure.

[0082] Figure 5An example of the content of a signaling message (such as a MAC-CE) is shown, the content indicating a set of components and a set of formats to be used to interpret bits indicating the set of components. As shown by reference numeral 510, the signaling message may include a format indicator and a component indicator for one or more component types. The component types are shown as PUCCH resource component types, PUCCH resource set component types, BWP component types, and CC component types. The signaling message may indicate a set of components corresponding to any combination of component types. In some aspects, the signaling message may indicate one or more components for only a single component type. In example 500, the signaling message indicates components for PUCCH resource component types, BWP component types, and CC component types but not for PUCCH resource set component types. However, other combinations may be different than Figure 5 The combination shown in .

[0083] As shown, the signaling message may indicate that format 2 is used to indicate one or more PUCCH resources of a PUCCH resource component type, format 1 is used to indicate a single BWP, and format 1 is used to indicate a single CC. In this case, the single BWP is explicitly identified as BWP 2, the single CC is explicitly identified as CC 1, and the PUCCH resources are indicated using a bitmap 101010101, which indicates even-numbered PUCCH resources (e.g., PUCCH resource ID 0, PUCCH resource ID 2, PUCCH resource ID 4, PUCCH resource ID 6, and PUCCH resource ID 8). In this case, as indicated by reference numeral 520, the UE 120 may apply the spatial relationship indicated in the signaling message to the PUCCH resources indicated in the bitmap on BWP 2 on CC 1.

[0084] In some aspects, the MAC-CE may be designed to have a fixed size so that the base station 110 can use the MAC-CE to indicate only a single combination of formats for the corresponding component type. In example 500, the single combination is format 2 for the PUCCH resource component type, format 1 for the BWP component type, and format 1 for the CC component type. In this case, the MAC-CE may have a fixed size (e.g., a fixed length), which may simplify the processing and / or generation of the MAC-CE and thereby save UE resources and base station resources.

[0085] In some aspects, the MAC-CE may be designed to have a fixed size so that the base station 110 can use the MAC-CE to indicate multiple combinations of formats for corresponding component types. For example, as shown by reference numeral 530, the MAC-CE may include a validity indicator. The validity indicator may indicate whether to use a component indicator in a signaling message to identify a component for a component type (e.g., when the validity indicator for the component type has a first value (such as 1)), or whether to apply a spatial relationship to all components (e.g., configured components) with the component type (e.g., when the validity indicator for the component type has a second value (such as 0)). In example 500, the validity indicator is shown as a bitmap 011, where the first bit (0) corresponds to the PUCCH resource component type, the second bit (1) corresponds to the BWP component type, and the third bit (1) corresponds to the CC component type. In this case, the UE 120 uses the component indicator to identify the BWP and CC, and ignores the component indicator for the PUCCH resource. Therefore, as indicated by reference numeral 540, UE 120 applies the spatial relationship indicated in the signaling message to all PUCCH resources on BWP 2 on CC 1.

[0086] In some aspects, a validity indicator may be included in the body of the MAC-CE to indicate which component indicators are valid (e.g., will be used to identify components to which spatial relations are to be applied) and which component indicators are invalid (e.g., will not be used to identify components to which spatial relations are to be applied). In some aspects, the validity indicator may be included in a subheader of the MAC-CE and / or a length field of the MAC-CE. In this case, the MAC-CE may have a variable length.

[0087] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described in Figure 5 Examples described.

[0088] Figure 6 6 is a diagram illustrating an example process 600, performed, for example, by a UE, in accordance with various aspects of the present disclosure. Example process 600 is an example of operations in which a UE (eg, UE 120, etc.) performs operations associated with group-based beam indication and signaling.

[0089] like Figure 6As shown, in some aspects, process 600 may include receiving a downlink beam indication for at least one of a channel, a resource, a set of resources, a bandwidth portion, or a component carrier (block 610). For example, the UE (e.g., using receive processor 258, controller / processor 280, memory 282, etc.) may receive a downlink beam indication for at least one of a channel, a resource, a set of resources, a bandwidth portion, or a component carrier, as described above.

[0090] As in Figure 6 As further shown in FIG. 6 , in some aspects, process 600 may include using the downlink beam indication for a group of channels, resources, resource sets, bandwidth portions, or component carriers (block 620). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may use the downlink beam indication for a group of channels, resources, resource sets, bandwidth portions, or component carriers, as described above.

[0091] Process 600 may include additional aspects, such as any single implementation or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0092] In a first aspect, the downlink beam indication comprises at least one of a transmission configuration indicator (TCI) state or a quasi co-location (QCL) relationship. In a second aspect, alone or in combination with the first aspect, a downlink beam indication is received for a first physical downlink shared channel (PDSCH) and for at least one of a first bandwidth part or a first component carrier, and the downlink beam indication is used for a second PDSCH and for at least one of a second bandwidth part or a second component carrier. In a third aspect, alone or in combination with one or more of the first and second aspects, a downlink beam indication is received for a first control resource set (CORESET) and a first physical downlink shared channel (PDSCH) on a first bandwidth part or a first component carrier, and the downlink beam indication is used for a second CORESET and a second PDSCH on a second bandwidth part or a second component carrier.

[0093] In a fourth aspect, alone or in combination with one or more of the first to third aspects, a downlink beam indication is received for a first control resource set (CORESET) and for at least one of a first bandwidth part or a first component carrier, and the downlink beam indication is used for a second CORESET on at least one of a second bandwidth part or a second component carrier. In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the beam indication is stored in a configuration or activated for use.

[0094] Although aspects are described above in conjunction with downlink beam indications, similar operations may be performed for uplink beam indications. For example, a UE may receive an uplink beam for at least one of a channel, a resource, a resource set, a bandwidth portion, or a component carrier; and the uplink beam indication may be used for a group of channels, resources, resource sets, bandwidth portions, or component carriers. In one aspect, alone or in combination with one or more aspects described elsewhere herein, a single activated and / or configured beam indication for use on a particular uplink and / or downlink channel or resource on a bandwidth portion and / or component carrier may be applied to a group of channels, resources, resource sets, bandwidth portions, and / or component carriers.

[0095] although Figure 6 An example block diagram of process 600 is shown, but in some aspects, process 600 may include Figure 6 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the process 600. Additionally or alternatively, two or more blocks of the process 600 may be executed in parallel.

[0096] Figure 7 7 is a diagram illustrating an example process 700, performed, for example, by a UE, in accordance with various aspects of the present disclosure. Example process 700 is an example of operations in which a UE (eg, UE 120, etc.) performs operations associated with group-based beam indication and signaling.

[0097] like Figure 7 As shown in , in some aspects, process 700 may include receiving an indication of a spatial relationship and a plurality of physical uplink control channel (PUCCH) resources to which the spatial relationship is to be applied (block 710). For example, a UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may receive an indication of a spatial relationship and a plurality of physical uplink control channel (PUCCH) resources to which the spatial relationship is to be applied, as described above.

[0098] like Figure 7 As further shown in FIG. 7 , in some aspects, process 700 may include using the spatial relationship to transmit on one or more PUCCH resources in the plurality of PUCCH resources (block 720). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may use the spatial relationship to transmit on one or more PUCCH resources in the plurality of PUCCH resources, as described above.

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

[0100] In a first aspect, the plurality of PUCCH resources are indicated using one or more component identifiers including at least one of a PUCCH resource identifier, a PUCCH resource set identifier, a bandwidth part identifier, a component carrier identifier, or a combination thereof. In a second aspect, alone or in combination with the first aspect, a component identifier of the one or more component identifiers is indicated using one of the following: a first format that explicitly indicates a single component identifier for a component, a second format that includes a bitmap indicating component identifiers from a configured set of component identifiers, a third format that indicates all component identifiers for a component, or a fourth format that indicates a number of component identifiers and a corresponding component identifier for each of the number of component identifiers.

[0101] In a third aspect, alone or in combination with one or more of the first and second aspects, a format to be used to indicate a component identifier in the one or more component identifiers is signaled to the UE. In a fourth aspect, alone or in combination with one or more of the first to third aspects, the indication is received in a single medium access control (MAC) control element (MAC-CE).

[0102] In a fifth aspect, either alone or in combination with one or more of the first to fourth aspects, a single MAC-CE is used to indicate the spatial relationship, the plurality of PUCCH resources, and a format set for interpreting a bit set for indicating a component set, the component set indicating the plurality of PUCCH resources. In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the component set is explicitly indicated by the format set. In a seventh aspect, either alone or in combination with one or more of the first to sixth aspects, a single MAC-CE has a fixed length. In an eighth aspect, either alone or in combination with one or more of the first to seventh aspects, a component set is indicated by a format set and a validity indicator, the validity indicator indicating whether a format in the format set will be used to identify the corresponding component or whether all component identifiers for the component will be used to identify the PUCCH resources. In a ninth aspect, either alone or in combination with one or more of the first to eighth aspects, a single MAC-CE has a fixed length, and the validity indicator is included in the body of the MAC-CE. In a tenth aspect, alone or in combination with one or more of the first to ninth aspects, a single MAC-CE has a variable length, and the validity indicator is included in a subheader of the MAC-CE.

[0103] although Figure 7 An example block diagram of process 700 is shown, but in some aspects, process 700 may include Figure 7Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the process 700. Additionally or alternatively, two or more blocks of the process 700 may be executed in parallel.
