Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus associated with active bandwidth part (BWP) for beam application time in a unified transmit configuration indication (TCI) framework. Background Art

[0002] 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 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).

[0003] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0004] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectrum efficiency; reducing costs; improving services; utilizing new spectrum; and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink to better integrate with other open standards; and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0005] Some aspects described herein relate to a user equipment (UE) for wireless communication. The UE may include a memory and one or more processors coupled to the memory. The one or more processors may be configured to receive a downlink control information (DCI) message carrying a transmit configuration indication (TCI) state indication from a network node. The one or more processors may be configured to apply the TCI state indication after a beam application time based at least in part on an active bandwidth portion associated with the TCI state indication. The one or more processors may be configured to communicate with the network node using a beam associated with the TCI state indication after applying the TCI state indication.

The method may include: communicating with the network node using a beam associated with the TCI status indication after applying the TCI status indication.

[0007] Some aspects described herein relate to a non-transitory computer-readable medium storing an instruction set for wireless communication by a UE. The instruction set, when executed by one or more processors of the UE, may cause the UE to receive a DCI message carrying a TCI status indication from a network node. The instruction set, when executed by one or more processors of the UE, may cause the UE to apply the TCI status indication after a beam application time of an active bandwidth portion associated with the TCI status indication based at least in part on the TCI status indication. The instruction set, when executed by one or more processors of the UE, may cause the UE to communicate with the network node using a beam associated with the TCI status indication after applying the TCI status indication.

The apparatus may include: means for receiving a DCI message carrying a TCI status indication from a network node. The apparatus may include: means for applying the TCI status indication after a beam application time based at least in part on an active bandwidth portion associated with the TCI status indication. The apparatus may include: means for communicating with the network node using a beam associated with the TCI status indication after applying the TCI status indication.

[0019] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method that is practiced using other structures, functionality, or structure and functionality other than the various aspects of the disclosure set forth herein or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present claim.

[0020] 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"). These elements may 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.

[0021] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), 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).

[0022] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0023] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.

[0024] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0025] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions, but not another base station function. In this manner, a single device may include more than one base station.

[0026] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0027] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0028] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link. In some aspects, the network controller 130 may be, or may include, a CU or a core network device.

[0029] UE 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 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 computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.

[0030] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0031] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may 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 may be deployed.

[0032] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). 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, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0033] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the "below 6 GHz" band. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0034] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0035] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0036] In some aspects, UE 120 may include a communication manager 140. As described in greater detail elsewhere herein, communication manager 140 may: receive a downlink control information (DCI) message carrying a transmit configuration indication (TCI) state indication from network node 110; apply the TCI state indication after a beam application time based at least in part on an active bandwidth portion associated with the TCI state indication; and communicate with network node 110 using a beam associated with the TCI state indication after applying the TCI state indication. Additionally or alternatively, communication manager 140 may perform one or more other operations described herein.

[0037] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0038] Figure 22 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0039] At the network node 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQI) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0040] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0041] 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 network node 110 via the communication unit 294.

[0042] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0043] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 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 operations described herein (eg, with reference to Figures 4 to 6 ) or any aspects of any of the methods described herein.

[0044] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 4 to 6 ) or any aspects of any of the methods described herein.

[0045] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with the active bandwidth part (BWP) for beam application time in the unified TCI framework, as described in more detail elsewhere herein. Figure 2 Any other component of may perform or direct e.g. Figure 5 10 and / or operations of process 500 and / or other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, conversion and / or interpretation), may cause the one or more processors, UE 120 and / or network node 110 to perform or direct, for example, Figure 5 The process 500 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0046] In some aspects, the UE 120 includes means for receiving a DCI message carrying a TCI status indication from the network node 110; means for applying the TCI status indication after a beam application time based at least in part on an active bandwidth portion associated with the TCI status indication; and / or means for communicating with the network node 110 using the beam associated with the TCI status indication after applying the TCI status indication. Means for the UE 120 to perform operations described herein may include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0047] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0048] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0049] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0050] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0051] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0052] Figure 3 5 is a diagram illustrating an example 500 of using beams for access link communication between a network node and a UE according to the present disclosure. Figure 3 As shown in FIG. 1 , a network node 110 and a UE 120 may communicate with each other in a wireless network (eg, wireless network 100 ).

[0053] The network node 110 may transmit to a UE 120 located within the coverage area of ​​the network node 110. The network node 110 and the UE 120 may be configured for beamformed communication, wherein the network node 110 may transmit in the direction of the UE 120 using a directional downlink transmit beam, and the UE 120 may receive the transmission using a directional downlink receive beam. Each downlink transmit beam may have an associated beam ID, beam direction, or beam symbol, etc. The network node 110 may transmit downlink communications via one or more downlink transmit beams 305.

[0054] UE 120 may attempt to receive a downlink transmission via one or more downlink receive beams 310, which may be configured using different beamforming parameters at a receive circuit of UE 120. UE 120 may identify a specific downlink transmit beam 305 (shown as downlink transmit beam 305-A) and a specific downlink receive beam 310 (shown as downlink receive beam 310-A) that provide relatively good performance (e.g., having the best channel quality among different measured combinations of downlink transmit beams 305 and downlink receive beams 310). In some examples, UE 120 may send an indication of which downlink transmit beam 305 UE 120 identified as a preferred downlink transmit beam, which network node 110 may select for transmission to UE 120. Thus, UE 120 can obtain and maintain a beam pair link (BPL) with network node 110 for downlink communication (e.g., a combination of downlink transmit beam 305-A and downlink receive beam 310-A), which beam pair link (BPL) can be further refined and maintained based on one or more established beam refinement processes.

[0055] A downlink beam (such as a downlink transmit beam 305 or a downlink receive beam 310) may be associated with a TCI state. The TCI state may indicate a directionality or characteristic of the downlink beam, such as one or more quasi-co-location (QCL) properties of the downlink beam. The QCL properties may include, for example, Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters, etc. In some examples, each downlink transmit beam 305 may be associated with a synchronization signal block (SSB), and the UE 120 may indicate a preferred downlink transmit beam 305 by transmitting an uplink transmission in the resources of the SSB associated with the preferred downlink transmit beam 305. A specific SSB may have an associated TCI state (e.g., for an antenna port or for beamforming). In some examples, the network node 110 may indicate a downlink transmit beam 305 based at least in part on an antenna port QCL characteristic that may be indicated by a TCI state. For different QCL types (e.g., QCL types for different combinations of Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters, etc.), the TCI state can be associated with a set of downlink reference signals (e.g., SSB, and aperiodic, periodic, or semi-persistent channel state information reference signals (CSI-RS)). In the case where the QCL type indicates spatial reception parameters (e.g., QCL type D), the QCL type can correspond to analog receive beamforming parameters of the downlink receive beam 310 at the UE 120. Therefore, the UE 120 can select the corresponding downlink receive beam 310 from the BPL set based at least in part on the network node 110 indicating the downlink transmit beam 305 via the TCI state indication.

[0056] The network node 110 may maintain an activated TCI state set for downlink shared channel transmission and an activated TCI state set for downlink control channel transmission. The activated TCI state set for downlink shared channel transmission may correspond to a beam used by the network node 110 for downlink transmission on a physical downlink shared channel (PDSCH). The activated TCI state set for downlink control channel communication may correspond to a beam that the network node 110 can use for downlink transmission on a physical downlink control channel (PDCCH) or in a control resource set (CORESET). The UE 120 may also maintain an activated TCI state set for receiving downlink shared channel transmissions and / or downlink control channel transmissions. In the case where the TCI state is activated for the UE 120, the UE 120 may have one or more antenna configurations based at least in part on the TCI state, and the UE 120 may not need to reconfigure the antenna or antenna weighting configuration. In some examples, the set of activated TCI states (eg, activated PDSCH TCI states and activated CORESET TCI states) for UE 120 may be configured by a configuration message, such as a radio resource control (RRC) message (eg, an RRCReconfiguration message).

[0057] Similarly, for uplink communications, UE 120 may transmit in the direction of network node 110 using a directional uplink transmit beam, and network node 110 may receive the transmission using a directional uplink receive beam. Each uplink transmit beam may have an associated beam ID, beam direction, or beam symbol, etc. UE 120 may transmit uplink communications via one or more uplink transmit beams 315.

[0058] The network node 110 may receive uplink transmissions via one or more uplink receive beams 320. The network node 110 may identify a particular uplink transmit beam 315 (shown as uplink transmit beam 315-A) and a particular uplink receive beam 320 (shown as uplink receive beam 320-A) that provide relatively good performance (e.g., having the best channel quality for different measured combinations of uplink transmit beams 315 and uplink receive beams 320). In some examples, the network node 110 may send an indication of which uplink transmit beam 315 the network node 110 identified as a preferred uplink transmit beam, which the network node 110 may select for transmission from the UE 120. Thus, UE 120 and network node 110 may obtain and maintain a BPL for uplink communications (e.g., a combination of uplink transmit beam 315-A and uplink receive beam 320-A), which may be further refined and maintained according to one or more established beam refinement processes. An uplink beam (such as uplink transmit beam 315 or uplink receive beam 320) may be associated with a spatial relationship. The spatial relationship may indicate a directionality or characteristic of the uplink beam (similar to one or more QCL attributes), as described above.

[0059] Additionally or alternatively, such as Figure 3 As shown in , the network node 110 and the UE 120 may communicate using a unified TCI framework, in which case the network node 110 may indicate a TCI state that the UE 120 will use for beamforming uplink communications. For example, in the unified TCI framework, a joint TCI state (which may be referred to as a joint downlink and uplink TCI state) may be used to indicate a common beam that the UE 120 will use for downlink and uplink communications. In this case, the joint downlink and uplink TCI state may include at least one source reference signal to provide a reference (or UE assumption) for determining QCL characteristics for downlink communications or a spatial filter for uplink communications. For example, the joint downlink and uplink TCI state can be associated with: providing one or more source reference signals for UE-specific PDSCH reception in a component carrier and common QCL information for one or more CORESETs, or providing a reference to determine one or more common uplink transmit spatial filters for physical uplink shared channel (PUSCH) transmission based on a dynamically granted or configured grant or one or more dedicated physical uplink control channel (PUCCH) resources in a component carrier.

[0060] Additionally or alternatively, the unified TCI framework may support separate downlink TCI states and uplink TCI states to accommodate separate downlink beam indications and uplink beam indications (e.g., in the case where the best uplink beam does not correspond to the best downlink beam, or vice versa). In such cases, each valid uplink TCI state may be associated with a source reference signal to indicate an uplink transmit beam (e.g., a target uplink reference signal or a target uplink channel) for a target uplink communication. For example, the source reference signal may be a sounding reference signal (SRS), an SSB, or a CSI-RS, etc., and the target uplink communication may be a physical random access channel (PRACH), a PUCCH, a PUSCH, an SRS, and / or a DMRS (e.g., for a PUCCH or a PUSCH), etc. In this way, supporting a joint TCI state or separate downlink TCI states and uplink TCI states may enable a unified TCI framework for downlink and uplink communications, and / or may enable the network node 110 to indicate various uplink QCL relationships (e.g., Doppler shift, Doppler spread, average delay or delay spread, etc.) for uplink TCI communications.

[0061] In a wireless network supporting a unified TCI framework, a network node may send a DCI message carrying a TCI status indication to change a downlink beam, an uplink beam, and / or a joint downlink and uplink beam used by a UE to communicate with the network node, and the UE may subsequently send a hybrid automatic repeat request (HARQ) feedback to the network node to confirm the TCI status indication. In general, the UE may apply the TCI status indication starting from a first time slot that is at least a configured number of symbols after the last symbol of an uplink transmission carrying HARQ feedback. Thus, the configured number of symbols may generally define a beam application time that starts after the last symbol of an uplink transmission carrying HARQ feedback and has a duration that depends on one or more active BWPs in one or more sets of component carriers to which an updated beam associated with the TCI status indication is applied. For example, because the beam application time is based on the configured number of symbols, the duration of the beam application time may depend on the subcarrier spacing that defines the symbol duration for the active BWP. However, the component carrier and / or active BWP used by the UE for communication may change during the duration between the time slot in which the UE receives a DCI message carrying a TCI status indication and the time slot in which the UE sends HARQ feedback for the TCI status indication. Therefore, there may be ambiguity as to how the UE determines the component carrier and / or active BWP used to determine the beam application time (e.g., if the UE will apply the TCI status indication earlier or later than the network node, it will potentially degrade access link performance). Therefore, some aspects described herein relate to techniques for determining the component carrier and / or active BWP to be used to determine the beam application time for a TCI status indication associated with a unified TCI framework.

[0062] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0063] Figure 4 4 is a diagram illustrating an example 400 associated with an active BWP for beam application time in a unified TCI framework according to the present disclosure. As described herein, example 400 includes communication between a network node (e.g., network node 110) and a UE (e.g., UE 120). In some aspects, the network node and the UE may communicate in a wireless network such as wireless network 100. The network node and the UE may communicate via a wireless access link (which may include an uplink and a downlink).

[0064] As in Figure 4In and as shown by reference numeral 410, a network node may send and a UE may receive a DCI message carrying a TCI state indication. For example, in some aspects, the TCI state indication may include a parameter (e.g., DLorJointTCIState) for indicating a downlink beam to be used by the UE to receive one or more downlink transmissions from the network node and / or a joint downlink and uplink beam to be used by the UE to receive one or more downlink transmissions from the network node and to send one or more uplink transmissions to the network node. Additionally or alternatively, the TCI state indication may include a parameter (e.g., UL TCIState) for indicating an uplink beam to be used by the UE to send one or more uplink transmissions to the network node. In some aspects, the DCI message carrying the TCI state indication may be sent with a downlink assignment to schedule a PDSCH transmission to the UE, or the DCI message may be sent without a downlink assignment. Additionally or alternatively, the DCI message may include an uplink grant indicating PUSCH resources for the UE.

[0065] As in Figure 4 In and as indicated by reference numeral 420, the UE may send, and the network node may receive, an uplink transmission carrying HARQ feedback for a TCI status indication. For example, in a case where the DCI message carrying the TCI status indication does not include a downlink assignment (e.g., no PDSCH transmission is scheduled to the UE), the UE may send HARQ feedback for the TCI status indication in a PUCCH transmission corresponding to the DCI message carrying the TCI status indication. Additionally or alternatively, the UE may include HARQ feedback for the TCI status indication in a PUSCH transmission corresponding to the DCI message carrying the TCI status indication (e.g., where the DCI message includes a downlink grant and if the PUSCH transmission overlaps with the PUCCH transmission carrying the HARQ feedback, the HARQ feedback is included in the PUSCH transmission). Additionally or alternatively, in a case where the DCI message carrying the TCI indication includes a downlink assignment, the UE may send HARQ feedback for the TCI status indication in a PUCCH transmission or a PUSCH transmission carrying HARQ-ACK information corresponding to the PDSCH scheduled by the DCI message carrying the TCI status indication.

[0066] As in Figure 4, and further shown by reference numeral 430, the UE may determine the beam application time based on the subcarrier spacing of the active BWP in the set of component carriers to which the TCI status indication is applied. For example, in some aspects, the network node may configure a parameter (e.g., BeamAppTime_r17) defining the number of symbols Y, and the TCI status indication provided in the DCI message may generally apply to the first time slot, which is at least the configured number of symbols after the last symbol of the PUCCH or PUSCH carrying HARQ feedback for the TCI status indication. In general, the first time slot after the last symbol of the PUCCH or PUSCH and the absolute time duration corresponding to the configured number of symbols may be determined on the active BWP included in the set of active BWPs associated with one or more component carriers (or sets of component carriers) associated with the beam indication associated with the TCI status indication. However, in some cases, the TCI status indication may be applicable to multiple component carriers and / or multiple BWPs that may be associated with different subcarrier spacings, which may result in changes in the possible duration of the beam application time. For example, because the symbol duration varies according to the subcarrier spacing (e.g., a larger subcarrier spacing is associated with a shorter symbol duration, and vice versa), the absolute time duration corresponding to the beam application time can be determined as Y×s 历时 , where s 历时 is the duration of a symbol associated with the subcarrier spacing configured for the BWP.

[0067] Therefore, in the case where the TCI status indication is applicable to multiple component carriers and / or multiple BWPs that may be associated with different subcarrier spacings, the UE may be configured to determine the beam application time (e.g., to identify the first timeslot that is at least a configured number of symbols after the last symbol of the PUCCH or PUSCH carrying the HARQ feedback for the TCI status indication) based on the active BWP with the smallest subcarrier spacing (e.g., the longest symbol duration) among the active BWPs associated with the component carrier to which the beam indication associated with the TCI status indication is applied. However, in some cases, there may be one or more BWP switches and / or cell changes between the timeslot when the DCI message carrying the TCI status indication is received and the timeslot when the UE sends the HARQ feedback for the TCI status indication, which may create ambiguity as to which component carrier(s) and / or active BWP to use to determine the beam application time. For example, in Figure 4In the embodiment, a first BWP in a first component carrier set may be active in a time slot in which a DCI message carrying a TCI status indication is received, a second BWP in a second component carrier set may be active in a time slot in which the UE sends HARQ feedback for the TCI status indication, and a third BWP in a third component carrier set may be active between a time slot when the TCI status indication is received and a time slot in which the HARQ feedback for the TCI status indication is sent, wherein the TCI status indication may be indicated for all three component carriers.

[0068] Therefore, as shown by reference numeral 440-1, the active BWP used by the UE to determine the beam application time (e.g., based on the subcarrier spacing of the active BWP) may correspond to the active BWP having the smallest subcarrier spacing among one or more active BWPs associated with one or more component carriers to which the TCI status indication is applied in the time slot in which the DCI message carrying the TCI status indication is received (e.g., the BWP having the smallest subcarrier spacing among the BWPs included in the first component carrier set). Alternatively, as shown by reference numeral 440-2, the active BWP used by the UE to determine the beam application time may correspond to the active BWP having the smallest subcarrier spacing among one or more active BWPs associated with one or more component carriers to which the TCI status indication is applied in the time slot in which the UE sends HARQ feedback for the TCI status indication (e.g., the BWP having the smallest subcarrier spacing among the BWPs included in the second component carrier set). Alternatively, as shown by reference number 440-3, the active BWP used by the UE to determine the beam application time may correspond to an active BWP having the smallest subcarrier spacing among one or more active BWPs associated with one or more component carriers to which the TCI status indication is applied between the time slot in which the DCI message carrying the TCI status indication is received and the time slot in which the UE sends HARQ feedback for the TCI status indication (for example, a BWP having the smallest subcarrier spacing among the BWPs included in any one of the first component carrier set, the second component carrier set, and the third component carrier set).

[0069] As in Figure 4In and further shown by reference numeral 450, after the beam application time has elapsed, the UE may begin using the beam associated with the TCI state indication to communicate with the network node. For example, in some aspects, the UE may determine an active BWP for a symbol duration defining the beam application time using one or more of the techniques described above with respect to reference numerals 440-1, 440-2, and 440-3, and may apply the TCI state indication in a first time slot that is at least a configured number of symbols after a last symbol of an uplink transmission carrying HARQ feedback for the TCI state indication. In some aspects, after the TCI state has been applied, the updated beam associated with the TCI state indication may be used for downlink communications, uplink communications, or both downlink and uplink communications between the UE and the network node.

[0070] Thus, when the UE is about to transmit the last symbol of a PUCCH with HARQ-ACK information or a PUSCH with HARQ-ACK information corresponding to a DCI carrying a TCI state indication and having no downlink assignment or corresponding to a PDSCH scheduled by a DCI carrying a TCI state indication, and if the indicated TCI state is different from the previously indicated TCI state, the indicated DLorJointTCIState or UL-TCIstate should be applied starting from the first slot, which is at least BeamAppTime_r17 symbols after the last symbol of the PUCCH or PUSCH carrying the HARQ-ACK information. In some aspects, both the first slot and the BeamAppTime_r17 symbols are determined on an active BWP with a minimum subcarrier spacing among the active BWPs of the carrier to which the beam indication is applied in the slot in which the TCI state indication is received.

[0071] Additionally or alternatively, when the UE is about to send the last symbol of a PUCCH with HARQ-ACK information or a PUSCH with HARQ-ACK information corresponding to a DCI carrying a TCI state indication and having no downlink assignment or corresponding to a PDSCH scheduled by a DCI carrying a TCI state indication, and if the indicated TCI state is different from a previously indicated TCI state, the indicated DLorJointTCIState or UL-TCIstate should be applied starting from a first slot that is at least BeamAppTime_r17 symbols after the last symbol of the PUCCH or PUSCH carrying the HARQ-ACK information. In some aspects, both the first slot and the BeamAppTime_r17 symbols are determined on an active BWP with a minimum subcarrier spacing among the active BWPs of the carrier to which the beam indication is applied in the slot when the UE sends the HARQ-ACK information for the TCI state indication. For example, for beam application time in a unified TCI framework, the active BWP may be determined based on the active BWP with the smallest subcarrier spacing among the active BWPs of the application component carrier at the end of the PUCCH and / or PUSCH transmission carrying HARQ-ACK for the TCI status indication.

[0072] Additionally or alternatively, when the UE is about to send the last symbol of a PUCCH with HARQ-ACK information or a PUSCH with HARQ-ACK information corresponding to a DCI carrying a TCI state indication and having no downlink assignment or corresponding to a PDSCH scheduled by a DCI carrying a TCI state indication, and if the indicated TCI state is different from a previously indicated TCI state, the indicated DLorJointTCIState or UL-TCIstate should be applied starting from a first slot that is at least BeamAppTime_r17 symbols after the last symbol of the PUCCH or PUSCH carrying the HARQ-ACK information. In some aspects, both the first slot and the BeamAppTime_r17 symbols are determined on an active BWP with a minimum subcarrier spacing among the active BWPs of the carrier to which the beam indication is applied between the slot in which the TCI state indication is received and the slot in which the UE sends the HARQ-ACK information for the TCI state indication.

[0073] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0074] Figure 55 is a diagram illustrating an example process 500 performed, for example, by a UE according to the present disclosure. Example process 500 is an example of a UE (eg, UE 120) performing operations associated with an active BWP for beam application time in a unified TCI framework.

[0075] like Figure 5 As shown in FIG. 5 , in some aspects, process 500 may include receiving a DCI message carrying a TCI status indication from a network node (block 510). For example, a UE (e.g., using Figure 6 The communication manager 140 and / or receiving component 602 depicted in FIG. 6A may receive a DCI message carrying a TCI status indication from a network node, as described above.
