Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for transmit configuration indicator state selection for channel state information or physical downlink shared channel communications. Background Art

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / 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 base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink and uplink communications. A "downlink" (or "DL") refers to the communication link from a base station to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a base station.

[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) with a cyclic prefix (CP) (CP-OFDM) on the downlink and 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; as well as 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

[0042] A downlink beam may be associated with a Transmit Configuration Indicator (TCI) state. The TCI state may indicate the directionality or characteristics of a downlink beam, such as one or more quasi-co-location (QCL) characteristics of the downlink beam. QCL characteristics may include, for example, Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters. The TCI state may be associated with an aperiodic channel state information reference signal (A-CSI-RS), which is triggered by DCI and used for channel estimation. The TCI state may also be associated with downlink transmissions on the physical downlink shared channel (PDSCH). In a unified TCI state framework, a TCI state may be used to indicate more than one beam. The TCI state may be used to indicate a beam for a downlink channel or reference signal (RS) and / or an uplink channel or RS. There may be multiple types of unified TCI states. For example, a joint downlink / uplink common TCI state may indicate a common beam for at least one downlink channel or RS and at least one uplink channel or RS.

[0043] In some scenarios, a user equipment (UE) may receive a configuration of CSI reporting information for an A-CSI triggering state, which involves an A-CSI-RS received using an A-CSI-RS resource set. In a unified TCI framework for DCI for multiple transmit receive points (TRPs), QCL information (e.g., QCL-Info) may not be present in the CSI reporting information. Without such QCL information, the UE is unclear about which unified TCI states the UE is to apply to one or more A-CSI-RS resource sets. This uncertainty may result in a suboptimal unified TCI state selection for the A-CSI-RS, which will reduce the accuracy of the A-CSI and degrade communications. Degraded communications waste processing and signaling resources.

[0044] According to various aspects described herein, a UE may receive an indication of a unified TCI state to be applied to an A-CSI-RS resource set. In this way, the UE has clarity when providing A-CSI feedback in response to receiving DCI. A-CSI and associated communications will be improved. As a result, the UE saves processing and signaling resources. In some aspects, the configuration may indicate which TCI state applies to which A-CSI-RS resource set. In some aspects, the DCI may indicate this information. In some aspects, the DCI may include a codepoint in the TCI state selection field that indicates how the TCI state is applied to PDSCH communications.

[0045] 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. On the contrary, 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 will be appreciated by those skilled in the art 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 may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functionality, or structure and functionality in addition to 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 claims.

[0046] 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, or algorithms (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0047] Although various aspects may be described herein using terminology 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 post-5G (e.g., 6G) RATs.

[0048] 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 (illustrated as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (illustrated 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, meaning 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 disaggregated network node (sometimes referred to as a disaggregated base station), meaning 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)).

[0049] In some examples, network node 110 is or includes a network node (such as an RU) that communicates with UE 120 via a radio access link. In some examples, network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link. In some examples, network node 110 (such as a converged 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. 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, an RU, a CU, a mobility element of a network, a core network node, a network element, 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 using any suitable transport network via various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks.

[0050] In some examples, 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 ​​network node 110 and / or a network node subsystem serving that coverage area, depending on the context in which the term is used. Network node 110 may provide communication coverage for a macrocell, a picocell, a femtocell, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 120 with service subscriptions. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 associated with the femtocell (e.g., UEs 120 in a closed subscriber group (CSG)). A network node 110 for a macrocell may be referred to as a macro network node. A network node 110 for a picocell 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, 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).

[0051] In some aspects, the term "base station" or "network node" may refer to a converged 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 multiple 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.

[0052] 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 can relay transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110 d (e.g., a relay network node) may communicate with a network node 110 a (e.g., a macro network node) and a UE 120 d to facilitate communications between the network node 110 a and the UE 120 d. 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.

[0053] 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).

[0054] 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 backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0055] UEs 120 may be dispersed throughout 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 smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a 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 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, 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.

[0056] Some UEs 120 may be considered 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 can communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. The UE 120 may be included within a housing that houses components of the 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, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0057] Generally speaking, 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. A RAT may be referred to as a radio technology, air interface, etc. A 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.

[0058] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 can 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 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0059] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. 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 to 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0060] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz to 24.25 GHz). The frequency band falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation to more than 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0061] With the above examples in mind, unless otherwise specifically stated, it should be understood that if the term "sub-6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be below 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, 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, 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.

[0062] In some aspects, a UE (e.g., UE 120) may include a communications manager 140. As described in greater detail elsewhere herein, the communications manager 140 may receive a configuration for at least one A-CSI-RS resource set. The communications manager 140 may receive an indication of a first unified TCI state and a second unified TCI state. The communications manager 140 may receive DCI triggering an A-CSI state associated with the at least one A-CSI-RS resource set. The communications manager 140 may apply at least one of the first unified TCI state or the second unified TCI state to the at least one A-CSI-RS resource set. The communications manager 140 may receive one or more A-CSI-RS using at least one of the first unified TCI state or the second unified TCI state applied.

[0063] In some aspects, the communications manager 140 may receive a radio resource control (RRC) message that configures the UE to receive a two-bit TCI state selection field. The communications manager 140 may receive a DCI that includes a codepoint in the two-bit TCI state selection field. The communications manager 140 may apply a unified TCI state corresponding to the codepoint to a PDSCH demodulation reference signal (DMRS) port for a PDSCH opportunity scheduled or activated by the DCI. The communications manager 140 may receive PDSCH communications using the unified TCI state. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0064] In some aspects, a network entity (e.g., network node 110) may include a communication manager 150. As described in greater detail elsewhere herein, the communication manager 150 may send a configuration for at least one A-CSI-RS resource set. The communication manager 150 may send an indication of a first unified TCI state and a second unified TCI state. The communication manager 150 may send a DCI that triggers an A-CSI state associated with the at least one A-CSI-RS resource set. The communication manager 150 may apply at least one of the first unified TCI state or the second unified TCI state to the at least one A-CSI-RS resource set. The communication manager 150 may send one or more A-CSI-RS using the one or more applied unified TCI states.

[0065] In some aspects, the communications manager 150 may send an RRC message configuring the UE to receive a two-bit TCI state selection field. The communications manager 150 may send DCI including a codepoint in the two-bit TCI state selection field. The communications manager 150 may apply a unified TCI state corresponding to the codepoint to the PDSCH DMRS port for the PDSCH opportunity scheduled or activated by the DCI. The communications manager 150 may send PDSCH communications using the unified TCI state. Additionally or alternatively, the communications manager 150 may perform one or more other operations described herein.

[0066] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0067] Figure 22 is a diagram illustrating 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 through 234t, such as T antennas (T ≥ 1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R ≥ 1). The network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and a modem 232. 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 radio frequency components, such as one or more CUs or one or more DUs, that facilitate direct communication with the UE 120.

[0068] At network node 110, transmit processor 220 may receive data intended for UE 120 (or a group of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120 and may provide data symbols for UE 120. 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. 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., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, as 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 through 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 frequency upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 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 through 234t).

[0069] At the UE 120, a set of antennas 252 (shown as antennas 252a through 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 through 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 the 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, if 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 a 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, among other things, 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. In some examples, one or more components of the UE 120 may be included in a housing 284.

[0070] 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.

[0071] 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 groups of antenna elements, and / or one or more antenna arrays, etc. An antenna panel, antenna group, group of antenna elements, and / or antenna array may include one or more antenna elements (within a single housing or multiple housings), a group of coplanar antenna elements, a group of non-coplanar antenna elements, and / or 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.

[0072] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. 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, if applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted 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 execute the instructions herein (eg, reference Figures 4 to 17 ) any aspects of any method described in the method.

[0073] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., a demodulator component (shown as DEMOD) of modem 232), detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include a communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, modem 232 of network node 110 may include a modulator and a demodulator. In some examples, 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 execute the instructions herein (e.g., reference 242). Figures 4 to 17 ) any aspects of any method described in the method.

[0074] A controller / processor of a network entity (e.g., controller / processor 240 of network node 110), controller / processor 280 of UE 120, and / or Figure 2 Any other components 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 TCI state selection for A-CSI and PDSCH as described in more detail elsewhere herein. Figure 2 Any other component of the may perform or direct e.g. Figure 12 The process of 1200 Figure 13 The process of 1300 Figure 14 The process of 1400 Figure 15 1500 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for a network entity 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 communications. For example, the one or more instructions, when executed (e.g., directly or after compilation, conversion, and / or interpretation) by one or more processors of a network entity and / or UE 120, may cause the one or more processors, UE 120, and / or the network entity to perform or direct, for example, Figure 12 The process of 1200 Figure 13 The process of 1300 Figure 14 The process of 1400 Figure 15 The operations of process 1500 and / or other processes described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0075] In some aspects, a UE (e.g., UE 120) includes: means for receiving a configuration for at least one A-CSI-RS resource set; means for receiving an indication of a first unified transmit configuration indicator (TCI) state and a second unified TCI state; means for receiving downlink control information (DCI) triggering an A-CSI state associated with the at least one A-CSI-RS resource set; means for applying at least one of the first unified TCI state or the second unified TCI state to the at least one A-CSI-RS resource set; and / or means for receiving one or more A-CSI-RS using at least one of the applied first unified TCI state or the second unified TCI state. Means for the UE to perform the operations described herein may include, for example, one or more of the following: the communications 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.

[0076] In some aspects, the UE includes: means for receiving an RRC message configuring the UE to receive a two-bit TCI state selection field; means for receiving DCI including a codepoint in the two-bit TCI state selection field; means for applying a unified TCI state corresponding to the codepoint to PDSCH DMRS ports for PDSCH opportunities scheduled or activated by the DCI; and / or means for receiving PDSCH communications using the unified TCI state.

[0077] In some aspects, a network entity (e.g., network node 110) includes: means for sending a configuration for at least one A-CSI-RS resource set; means for sending an indication of a first unified TCI state and a second unified TCI state; means for sending a DCI that triggers an A-CSI state associated with the at least one A-CSI-RS resource set; means for applying at least one of the first unified TCI state or the second unified TCI state to the at least one A-CSI-RS resource set; and / or means for sending one or more A-CSI-RS using one or more applied unified TCI states.

[0078] In some aspects, the network entity includes: means for sending an RRC message configuring the UE to receive a two-bit TCI state selection field; means for sending DCI including a codepoint in the two-bit TCI state selection field; means for applying a unified TCI state corresponding to the codepoint to PDSCH DMRS ports for PDSCH opportunities scheduled or activated by the DCI; and / or means for sending PDSCH communications using the unified TCI state.

[0079] Although Figure 2 The blocks in FIG. 2 are illustrated as distinct components, but the functionality described above with respect to these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to 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.

[0080] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0081] The deployment of a communication system such as a 5G NR system can be arranged in a variety of ways with various components or constituent parts. In a 5G NR system or network, a network node, a network entity, a mobility element of the network, a RAN node, a core network node, a network element, a base station or network equipment may be implemented in an aggregated architecture or a decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) performing base station functionality may 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. A “network entity” or a “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).

[0082] A converged base station (e.g., a converged 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, the 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 spread across one or more other network nodes. The DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and 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), among others.

[0083] Base station type operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated 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 scaling of the communication system by separating base station functionality into one or more units that can be deployed separately. A disaggregated 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. Each unit of the disaggregated base station may be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0084] Figure 3 FIG2 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. The decomposed base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed control units (such as a near-RT RIC 325 via an E2 link, a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via respective midhaul links (such as via an F1 interface). Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0085] Each of the units (including the CU 310, DU 330, RU 340) and the near-RT RIC 325, the non-RT RIC 315, and the SMO framework 305 may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more of the other units via the transmission medium. In some examples, each of the units may include a wired interface configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, and a wireless interface that may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more of the other units via a wireless transmission medium, or both.

[0086] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, among others. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0087] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more higher physical (PHY) layers, at least in part according to a functional split (such as that defined by 3GPP). In some aspects, the one or more higher PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and the like. In some aspects, the DU 330 may also host one or more lower PHY layers, such as those implemented by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0088] Each RU 340 may implement low-layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions based on functional split (e.g., functional split defined by 3GPP) (such as low-layer functional split), such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0089] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the Open Cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements can include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some implementations, the SMO framework 305 can communicate with hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0090] The non-RT RIC 315 can be configured to include logic that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or in communication with the near-RT RIC 325 (e.g., via an A1 interface). The near-RT RIC 325 can be configured to include logic that enables near-real-time control and optimization of RAN elements and resources through data collection and actions via an interface (e.g., via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0091] In some implementations, the non-RT RIC 315 can receive parameters or external enrichment information from an external server to generate an AI / ML model to be deployed in the near-RT RIC 325. Such information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or from network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 can monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or through the creation of RAN management policies (such as A1 interface policies).

[0092] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0093] Figure 4 An example logical architecture of a distributed RAN 400 according to the present disclosure is illustrated.

[0094] The 5G access node 405 may include an access node controller 410. The access node controller 410 may be a CU of the distributed RAN 400. In some aspects, a backhaul interface to the 5G core network 415 may terminate at the access node controller 410. The 5G core network 415 may include a 5G control plane component 420 and a 5G user plane component 425 (e.g., a 5G gateway), and the backhaul interface for one or both of the 5G control plane and the 5G user plane may terminate at the access node controller 410. Additionally or alternatively, a backhaul interface to one or more neighboring access nodes 430 (e.g., another 5G access node 405 and / or an LTE access node) may terminate at the access node controller 410.

[0095] The access node controller 410 may include one or more TRPs 435 and / or may communicate with one or more TRPs (e.g., via an F1 control (F1-C) interface and / or an F1 user (F1-U) interface). The TRP 435 may be a DU of the distributed RAN 400. In some aspects, the TRP 435 may correspond to the above combined Figure 1 10. For example, different TRPs 435 may be included in different base stations 110. Additionally or alternatively, multiple TRPs 435 may be included in a single network node 110. In some aspects, the network node 110 may include a CU (e.g., an access node controller 410) and / or one or more DUs (e.g., one or more TRPs 435). In some cases, a TRP 435 may be referred to as a cell, a panel, an antenna array, or an array.

[0096] The TRP 435 may be connected to a single access node controller 410 or to multiple access node controllers 410. In some aspects, there may be dynamic configuration of split logical functions within the architecture of the distributed RAN 400. For example, the PDCP layer, RLC layer, and / or MAC layer may be configured to terminate at the access node controller 410 or the TRP 435.

[0097] In some aspects, multiple TRPs 435 may transmit communications (e.g., the same communication or different communications) in the same transmit time interval (TTI) (e.g., a slot, mini-slot, subframe, or symbol) or in different TTIs using different QCL relationships (e.g., different spatial parameters, different TCI states, different precoding parameters, and / or different beamforming parameters). In some aspects, the TCI state may be used to indicate one or more QCL relationships. A TRP 435 may be configured to provide traffic to a UE 120 individually (e.g., using dynamic selection) or jointly (e.g., using joint transmission with one or more other TRPs 435).

[0098] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0099] Figure 5 5 is a diagram illustrating an example 500 of multiple TRP (multi-TRP) communication (sometimes referred to as multi-panel communication) according to the present disclosure. Figure 5 As shown, multiple TRPs 505 can communicate with the same UE 120. TRP 505 can correspond to the above-mentioned Figure 4 TRP 435 as described.

[0100] Multiple TRPs 505 (shown as TRP A and TRP B) can communicate with the same UE 120 in a coordinated manner (e.g., using coordinated multipoint transmission) to improve reliability and / or increase throughput. The TRPs 505 can coordinate such communications via an interface between the TRPs 505 (e.g., a backhaul interface and / or an access node controller 410). When the TRPs 505 are co-located at the same network node 110 (e.g., when the TRPs 505 are different antenna arrays or panels of the same network node 110), the interface can have lower latency and / or higher capacity, and when the TRPs 505 are located at different base stations 110, the interface can have higher latency and / or lower capacity (compared to co-location). Different TRPs 505 can communicate with the UE 120 using different QCL relationships (e.g., different TCI states), different DMRS ports, and / or different layers (e.g., different layers in a multi-layer communication).

[0101] In a first multi-TRP transmission mode (e.g., Mode 1), a single physical downlink control channel (PDCCH) can be used to schedule downlink data communications for a single PDSCH. In this case, multiple TRPs 505 (e.g., TRP A and TRP B) can send communications to UE 120 on the same PDSCH. For example, communications can be sent using a single codeword with different spatial layers for different TRPs 505 (e.g., where one codeword is mapped to a first set of layers sent by a first TRP 505 and to a second set of layers sent by a second TRP 505). As another example, communications can be sent using multiple codewords, where different codewords are sent by different TRPs 505 (e.g., using different sets of layers). In either case, different TRPs 505 can use different QCL relationships (e.g., different TCI states) for different DMRS ports corresponding to different layers. For example, the first TRP 505 may use a first QCL relationship or a first TCI state for a first set of DMRS ports corresponding to a first set of layers, and the second TRP 505 may use a second (different) QCL relationship or a second (different) TCI state for a second (different) set of DMRS ports corresponding to a second (different) set of layers. In some aspects, the TCI state in the DCI (e.g., sent on the PDCCH, such as DCI format 1_0 or DCI format 1_1) may indicate a first QCL relationship (e.g., by indicating a first TCI state) and a second QCL relationship (e.g., by indicating a second TCI state). The first TCI state and the second TCI state may be indicated using a TCI field in the DCI. Generally speaking, in the multi-TRP transmission mode (e.g., mode 1), the TCI field may indicate a single TCI state (for single TRP transmission) or multiple TCI states (for multi-TRP transmission as discussed herein).

[0102] In a second multi-TRP transmission mode (e.g., mode 2), multiple PDCCHs may be used to schedule downlink data communications for multiple corresponding PDSCHs (e.g., one PDCCH for each PDSCH). In this case, a first PDCCH may schedule a first codeword to be transmitted by the first TRP 505, and a second PDCCH may schedule a second codeword to be transmitted by the second TRP 505. In addition, a first DCI (e.g., transmitted by the first TRP 505) may schedule a first PDSCH communication associated with a first set of DMRS ports having a first QCL relationship (e.g., indicated by a first TCI state) for the first TRP 505, and a second DCI (e.g., transmitted by the second TRP 505) may schedule a second PDSCH communication associated with a second set of DMRS ports having a second QCL relationship (e.g., indicated by a second TCI state) for the second TRP 505. In this case, the DCI (e.g., having DCI format 1_0 or DCI format 1_1) may indicate a corresponding TCI state corresponding to the DCI for the TRP 505. The TCI field of the DCI indicates the corresponding TCI state (e.g., the TCI field of the first DCI indicates a first TCI state and the TCI field of the second DCI indicates a second TCI state).

[0103] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0104] Figure 6 is a diagram illustrating example 600 of multi-TRP operation according to the present disclosure.

[0105] Example 600 illustrates that a single DCI (sDCI) for a multi-TRP PDSCH may include spatial division multiplexing (SDM), frequency division multiplexing (FDM), or time division multiplexing (TDM). Example 600 illustrates that in the case of multiple TRPs, the TRPs may use TDM cyclic mapping or TDM sequential mapping. Example 600 also illustrates that multiple DCI (mDCI) for a multi-TRP PDSCH may include DMRS for SDM.

[0106] Example 600 illustrates that TDM may be used for physical uplink control channel (PUCCH) repetition. Example 600 also illustrates that a single frequency network (SFN) may use SDM for a physical uplink shared channel (PUSCH) and / or PUCCH.

[0107] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0108] Figure 7 is a diagram illustrating an example 700 of CJTs and non-CJTs (NCJTs) for multiple TRPs according to the present disclosure.

[0109] CJT involves multiple transmitters, each transmitting a message with a phase that constructively combines at the receiver. CJT may include beamforming using antennas that are not co-located and correspond to different TRPs. CJT can improve signal power and spatial diversity in communications in NR networks.

[0110] For SDM-based NCJT, data is pre-decoded separately at different TRPs. For example, pre-decoder A is pre-decoded for one TRP, and pre-decoder B is pre-decoded for a separate TRP. This can be expressed as: The non-bold letters are used for data of pre-decoder A and the first TRP, and the bold letters are used for data of pre-decoder B and the second TRP. V A :4×1、V B :4×2 may indicate a precoder for a specific TRP and rank (indicated by the rank indicator (RI)). Data (RI TRP ×1)X A :1×1、X B :2×1 can indicate data through TRP and RI.

[0111] For CJT, data is pre-decoded jointly at different TRPs. For example, this can be expressed as: Predecoder V A :4×2, V B :4×2 and data(RI CJT ×1)X:2×1. Reference numeral 702 shows joint precoding for multiple TRPs, rather than separate precoding as shown for NCJT. Reference numeral 704 shows two layers being jointly precoded.

[0112] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0113] Figure 8 800, 810, and 820 are diagrams illustrating examples of beam management processes according to the present disclosure. Figure 8 As shown, examples 800, 810, and 820 include a UE 120 communicating with a network entity (e.g., network node 110) in a wireless network (e.g., wireless network 100). Figure 8The devices shown are provided as examples, and the wireless network may support communication and beam management between other devices (e.g., between UE 120 and network node 110 or TRP, between mobile terminal nodes and control nodes, between IAB child nodes and IAB parent nodes, and / or between scheduled nodes and scheduling nodes). In some aspects, UE 120 and network node 110 may be in a connected state (e.g., an RRC connected state).

[0114] like Figure 8 As shown, example 800 may include a network node (NN) 110 and a UE 120 communicating to perform beam management using CSI-RS. Example 800 depicts a first beam management procedure (e.g., P1 CSI-RS beam management). The first beam management procedure may be referred to as a beam selection procedure, an initial beam acquisition procedure, a beam scanning procedure, a cell search procedure, and / or a beam search procedure. Figure 8 As shown in example 800, CSI-RS may be configured to be sent from network node 110 to UE 120. CSI-RS may be configured to be periodic (e.g., using RRC signaling), semi-persistent (e.g., using MAC control element (MAC-CE) signaling), and / or aperiodic (e.g., using DCI).

[0115] The first beam management process may include the network node 110 performing beam scanning on multiple transmit (Tx) beams. The network node 110 may use each transmit beam used for beam management to transmit a CSI-RS. To enable the UE 120 to perform receive (Rx) beam scanning, the base station may transmit each CSI-RS multiple times (e.g., using repetition) within the same RS resource set using a transmit beam, so that the UE 120 can scan through the receive beam in multiple transmission instances. For example, if the network node 110 has a set of N transmit beams and the UE 120 has a set of M receive beams, the CSI-RS may be transmitted M times on each of the N transmit beams, so that the UE 120 can receive M instances of the CSI-RS per transmit beam. In other words, for each transmit beam of the network node 110, the UE 120 may perform beam scanning on the receive beam of the UE 120. Thus, the first beam management procedure may enable UE 120 to measure CSI-RS on different transmit beams using different receive beams to support selection of a network node 110 transmit beam / UE 120 receive beam pair. UE 120 may report the measurements to network node 110 to enable network node 110 to select one or more beam pairs for communication between network node 110 and UE 120. Although example 800 has been described in conjunction with CSI-RS, the first beam management procedure may also use synchronization signal blocks (SSBs) to perform beam management in a similar manner as described above.

[0116] like Figure 8 As shown, example 810 may include network node 110 and UE 120 communicating to perform beam management using CSI-RS. Example 810 depicts a second beam management procedure (e.g., P2 CSI-RS beam management). The second beam management procedure may be referred to as a beam refinement procedure, a base station beam refinement procedure, a TRP beam refinement procedure, and / or a transmit beam refinement procedure. Figure 8 As shown in example 810, a CSI-RS may be configured to be transmitted from network node 110 to UE 120. The CSI-RS may be configured as aperiodic (e.g., using DCI), or A-CSI. The second beam management procedure may include network node 110 performing beam scanning on one or more transmit beams. The one or more transmit beams may be a subset of all transmit beams associated with network node 110 (e.g., determined based at least in part on measurements reported by UE 120 in conjunction with the first beam management procedure). Network node 110 may transmit a CSI-RS using each of the one or more transmit beams used for beam management. UE 120 may measure each CSI-RS using a single (e.g., identical) receive beam (e.g., determined based at least in part on measurements performed in conjunction with the first beam management procedure). This second beam management procedure may enable the network node 110 to select the best transmit beam based at least in part on measurements of the CSI-RS reported by the UE 120 (eg, measured by the UE 120 using a single receive beam).

[0117] like Figure 8 As shown, example 820 depicts a third beam management process (e.g., P3 CSI-RS beam management). This third beam management process may be referred to as a beam refinement process, a UE beam refinement process, and / or a receive beam refinement process. Figure 8As shown in example 820, one or more CSI-RSs may be configured to be transmitted from the network node 110 to the UE 120. The CSI-RS may be configured to be aperiodic (e.g., using DCI). The third beam management procedure may include the network node 110 transmitting the one or more CSI-RSs using a single transmit beam (e.g., determined at least in part based on measurements reported by the UE 120 in conjunction with the first beam management procedure and / or the second beam management procedure). To enable the UE 120 to perform receive beam scanning, the base station may transmit the CSI-RS multiple times (e.g., using repetitions) within the same RS resource set using the transmit beam, such that the UE 120 can scan through one or more receive beams in multiple transmission instances. The one or more receive beams may be a subset of all receive beams associated with the UE 120 (e.g., determined at least in part based on measurements performed in conjunction with the first beam management procedure and / or the second beam management procedure). The third beam management process may enable the network node 110 and / or UE 120 to select the best receive beam based at least in part on reported measurements received from the UE 120 (e.g., reported measurements of the CSI-RS of the transmit beam using the one or more receive beams).

[0118] As indicated above, Figure 8 is provided as an example of a beam management process. Other examples of beam management processes can be found in the Figure 8 For example, the UE 120 and the network node 110 may perform the third beam management procedure before performing the second beam management procedure, and / or the UE 120 and the network node 110 may perform a similar beam management procedure to select a UE transmit beam.

[0119] Figure 9 9 is a diagram illustrating an example 900 of using beams for communication between a network entity (eg, network node 110) and a UE (eg, UE 120) according to the present disclosure. Figure 9 As shown, network node 110 and UE 120 may communicate with each other.

[0120] 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 network entity transmit beam (e.g., a BS transmit beam), and the UE 120 may receive the transmission using a directional UE receive beam. Each transmit beam may have an associated beam identifier (ID), a beam direction or beam symbol, etc. The network node 110 may transmit downlink communications via one or more transmit beams 905.

[0121] UE 120 may attempt to receive a downlink transmission via one or more UE receive beams 910, which may be configured using different beamforming parameters at a receive circuit of UE 120. UE 120 may identify a particular transmit beam 905 (illustrated as transmit beam 905-A) and a particular UE receive beam 910 (illustrated as UE receive beam 910-A) that provide relatively good performance (e.g., having the best channel quality for different measured combinations of transmit beams 905 and UE receive beams 910). In some examples, UE 120 may transmit an indication of which transmit beam 905 UE 120 identified as a preferred transmit beam, and network node 110 may select the preferred transmit beam for transmission to UE 120. Thus, UE 120 may obtain and maintain a beam pair link (BPL) for downlink communication with network node 110 (e.g., a combination of transmit beam 905-A and UE receive beam 910-A), which may be further refined and maintained according to one or more established beam refinement procedures.

[0122] A downlink beam (such as a transmit beam 905 or a UE receive beam 910) may be associated with a TCI state. The TCI state may indicate the directionality or characteristics of the downlink beam, such as one or more QCL characteristics of the downlink beam. The QCL characteristics may include, for example, Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters. In some examples, each transmit beam 905 may be associated with a synchronization signal block (SSB), and the UE 120 may indicate a preferred transmit beam 905 by transmitting an uplink transmission in the resources of the SSB associated with the preferred transmit beam 905. 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 the downlink transmit beam 905 based at least in part on the antenna port QCL characteristics that may be indicated by the TCI state. The TCI state may be associated with a downlink reference signal set (e.g., SSB and aperiodic, periodic, or semi-persistent CSI-RS) for different QCL types (e.g., QCL types for different combinations of Doppler shift, Doppler spread, average delay, delay spread, or spatial receive parameters, etc.) Where the QCL type indicates spatial receive parameters, the QCL type may correspond to simulated receive beamforming parameters for the UE receive beam 910 at the UE 120. Thus, the UE 120 may select a corresponding UE receive beam 910 from a set of BPLs based at least in part on the network node 110 indicating the transmit beam 905 via the TCI indication.

[0123] Network node 110 may maintain a set of activated TCI states for downlink shared channel transmissions and a set of activated TCI states for downlink control channel transmissions. The set of activated TCI states for downlink shared channel transmissions may correspond to beams used by network node 110 for downlink transmissions on the PDSCH. The set of activated TCI states for downlink control channel communications may correspond to beams that network entity 110 may use for downlink transmissions on the PDCCH or in a CORESET. UE 120 may also maintain the set of activated TCI states for receiving downlink shared channel transmissions and CORESET transmissions. If a TCI state is activated for UE 120, UE 120 may have one or more antenna configurations based at least in part on the TCI state, and UE 120 may not need to reconfigure antenna or antenna weighting configurations. In some examples, the set of activated TCI states (e.g., activated PDSCH TCI states and activated CORESET TCI states) for UE 120 may be configured by a configuration message (such as an RRC message).

[0124] Similarly, for uplink communications, UE 120 may transmit in the direction of network node 110 using a directional UE transmit beam, and network node 110 may receive the transmission using a directional receive beam. Each UE transmit beam may have an associated beam ID, beam direction, or beam symbol, etc. UE 120 may transmit uplink communications via one or more UE transmit beams 915.

[0125] The network node 110 may receive uplink transmissions via one or more receive beams 920 (e.g., BS receive beams). The network node 110 may identify specific UE transmit beams 915 (illustrated as UE transmit beam 915-A) and specific receive beams 920 (illustrated as receive beam 920-A) that provide relatively good performance (e.g., having the best channel quality for different measured combinations of UE transmit beams 915 and receive beams 920). In some examples, the network node 110 may send an indication of which UE transmit beam 915 the network node 110 has identified as a preferred UE transmit beam, which the network node 110 may select to transmit from the UE 120. Thus, the UE 120 and the network node 110 may obtain and maintain a BPL for uplink communications (e.g., a combination of UE transmit beam 915-A and receive beam 920-A), which may be further refined and maintained according to one or more established beam refinement procedures. An uplink beam, such as a UE transmit beam 915 or a BS receive beam 920, may be associated with a spatial relationship. The spatial relationship may indicate a directionality or characteristic (similar to one or more QCL characteristics) of the uplink beam, as described above.

[0126] 3GPP standard Release 17 establishes a unified TCI state framework, in which TCI states can be used to indicate more than one beam. TCI states can be used to indicate beams for downlink channels or reference signals (RS) and / or uplink channels or RS. There can be multiple types of unified TCI states. For example, a joint TCI state can indicate a common beam for at least one downlink channel or RS and at least one uplink channel or RS. This can be type 1 and can include at least UE-specific PDCCH, PDSCH, PUCCH, and PUSCH. A downlink TCI state can indicate a common beam for more than one downlink channel or RS. This can be type 2 and can include at least UE-specific PDCCH and PDSCH. An uplink TCI state can indicate a common beam for more than one uplink channel or RS. This can be type 3 and can include at least UE-specific PUCCH and PUSCH. Other types of unified TCI states may include a separate downlink single channel or RS TCI state indicating a beam for a single downlink channel or RS, a separate uplink single channel or RS TCI state indicating a beam for a single uplink channel or RS, or uplink spatial relationship information, such as a spatial relationship indicator (SRI), indicating a beam for a single uplink channel or RS.

[0127] A network entity may send a unified TCI state indication indicating a unified TCI state. The unified TCI state indication may provide QCL type 1 (e.g., for QCL type A) and QCL type 2 (e.g., for QCL type D) for the downlink or joint TCI state. The unified TCI state indication may also provide power control parameters for the downlink or joint TCI state, such as P0 value, α value, or cross-link interference (CLI) information. For the joint TCI state, the unified TCI state indication may indicate the path loss RS. For the uplink TCI state, the unified TCI state indication may indicate the RS (e.g., for a spatial filter) and / or power control parameters.

[0128] The UE may be configured for A-CSI, and A-CSI may be triggered by DCI. The configuration for the A-CSI triggering state may be included in the report configuration information, such as CSI-AssociatedReportConfigInfo of CSI-AperiodicTriggerState. A-CSI may relate to A-CSI-RS received using an A-CSI-RS resource set. In the unified TCI framework of sDCI for multiple TRPs, there may be no QCL information (e.g., QCL-Info) for A-CSI resource sets configured for CSI feedback and beam management. In the absence of such QCL information, it is unclear to the UE which unified TCI states the UE is to use for one or more A-CSI-RS resource sets. This uncertainty may result in a suboptimal unified TCI state selection for the A-CSI-RS, which will reduce the accuracy of the A-CSI and degrade the communication. The degraded communication wastes processing resources and signaling resources.

[0129] As indicated above, Figure 9 are provided as examples. Other examples can be found in the Figure 9 The examples described are different.

[0130] Figure 10 is a diagram illustrating an example 1000 of TCI state selection for an A-CSI-RS resource set according to the present disclosure.

[0131] According to various aspects described herein, a UE can receive an indication of a unified TCI state to be applied to an A-CSI-RS resource set. In this way, the UE has clarity when providing A-CSI feedback in response to receiving DCI. A-CSI and associated communications are improved. Consequently, the UE saves processing and signaling resources.

[0132] In some aspects, the DCI may include sDCI. QCL information may not be present in the CSI reporting configuration associated with the triggered A-CSI state. In some aspects, the network entity may send an indication of how to apply the unified TCI state in an RRC configuration. The configuration may include CSI reporting configuration information associated with the triggered A-CSI state (e.g., CSI-AssociatedReportConfigInfo of CSI-AperiodicTriggerState). The configuration may indicate to the UE whether to apply the first unified TCI state to the A-CSI-RS resource set or the second unified TCI state to the A-CSI-RS resource set.

[0133] In some aspects, a network entity may send an indication in a DCI of how to apply a unified TCI state. The configuration for using DCI to indicate the unified TCI state may be included in CSI reporting configuration information associated with a triggered A-CSI state (e.g., CSI-AssociatedReportConfigInfo of CSI-AperiodicTriggerState). The DCI may indicate to the UE that a first unified TCI state is to be applied to an A-CSI-RS resource set or a second unified TCI state is to be applied to an A-CSI-RS resource set.

[0134] Example 1000 illustrates the selection of a unified TCI state for A-CSI. As indicated by reference numeral 1025, the network entity 1010 may transmit a configuration for at least one A-CSI-RS set. The configuration may be provided in CSI report configuration information associated with a triggered A-CSI state (e.g., CSI-AssociatedReportConfigInfo of CSI-AperiodicTriggerState). As indicated by reference numeral 1030, the network entity 1010 may transmit an indication of a first unified TCI state and a second unified TCI state. As indicated by reference numeral 1035, the network entity 1010 may transmit DCI that triggers the A-CSI state.

[0135] As indicated by reference numeral 1040, the UE 1020 may apply a first unified TCI state and / or a second unified TCI state to the at least one A-CSI-RS resource set. In some aspects, the configuration may indicate that the UE 1020 is to apply the first unified TCI state or the second unified TCI state to the A-CSI-RS resource set. The at least one A-CSI-RS resource set may be a single A-CSI-RS resource set. In some aspects, if the A-CSI-RS is used for enhanced group-based beam reporting or NCJT CSI measurement, where the CSI report is associated with a first A-CSI-RS resource set and a second A-CSI-RS resource set, the configuration may indicate that both unified TCI states are to be applied. The mapping between the unified TCI states and the A-CSI-RS sets may be default or indicated by a scanning order. For example, the first unified TCI state may be applied to the first A-CSI-RS resource set, and the second unified TCI state may be applied to the second A-CSI-RS resource set. Through the scanning order indication, the mapping order may also be switched, where the first unified TCI state may be applied to the second A-CSI-RS resource set, and the second unified TCI state may be applied to the first A-CSI-RS resource set.

[0136] In some aspects, the DCI may indicate to the UE 1020 that a first unified TCI state or a second unified TCI state is to be applied to an A-CSI-RS resource set. The at least one A-CSI-RS resource set may be a single A-CSI-RS resource set. In some aspects, if the A-CSI-RS is used for enhanced group-based beam reporting or NCJT CSI measurement, where the CSI report is associated with a first A-CSI-RS resource set and a second A-CSI-RS resource set, the DCI (e.g., via the TCI field) may indicate that both unified TCI states are to be applied. The mapping between the unified TCI states and the A-CSI-RS sets may be default or indicated by a scanning order. For example, a first unified TCI state may be applied to a first A-CSI-RS resource set, and a second unified TCI state may be applied to a second A-CSI-RS resource set. The mapping order may also be switched by the scanning order indication, where the first unified TCI state may be applied to the second A-CSI-RS resource set, and the second unified TCI state may be applied to the first A-CSI-RS resource set. As indicated by reference numeral 1045 , the network entity 1010 may transmit the A-CSI-RS using the applied unified TCI state (including using the first unified TCI state and / or the second unified TCI state).

[0137] In some aspects, the DCI may include multiple DCIs for multiple TRPs. QCL information may not be present in the CSI reporting configuration associated with the triggered A-CSI state (e.g., the CSI-AssociatedReportConfigInfo of the CSI-AperiodicTriggerState). In some aspects, a control resource set (CORESET) pool index value (coresetPoolIndex value) may be provided in the CSI-AssociatedReportConfigInfo of the CSI-AperiodicTriggerState, and the UE 1020 may apply the indicated joint / downlink (DL) TCI state specific to the coresetPoolIndex value to the A-CSI-RS resource set. For example, the CORESET pool index value in the configuration may indicate to the UE 1020 that a first unified TCI state is to be applied to the one A-CSI-RS resource set or a second unified TCI state is to be applied to the one A-CSI-RS resource set.

[0138] In some aspects, the RRC configuration provided in the CSI-AssociatedReportConfigInfo of the CSI-AperiodicTriggerState for the aperiodic CSI-RS resource set may indicate that the UE 1020 is to apply a first indicated joint / DL TCI state or a second indicated joint / DL TCI state to the aperiodic CSI-RS resource set, wherein the first indicated joint / DL TCI state and the second indicated joint / DL TCI state correspond to the indicated joint / DL TCI states specific to coresetPoolIndex values ​​of 0 and 1, respectively. For example, the configuration may indicate that the UE 1020 is to apply a first unified TCI state to the one A-CSI-RS resource set based at least in part on the UE's CORESET pool index value of 0 (zero) or to apply a second unified TCI state to the one A-CSI-RS resource set based at least in part on the UE's CORESET pool index value of 1 (one).

[0139] In some aspects, two A-CSI-RS resource sets may be configured to be associated with an A-CSI reporting configuration (e.g., reportConfig), which is configured using an RRC parameter (e.g., groupBasedBeamReporting-r17). If one or more A-CSI-RS resources in the first A-CSI-RS resource set are not provided with any QCL information, then the first indicated joint / DL TCI state in the multi-TRP operation of a single DCI schedule or the indicated joint / DL TCI state specific to a coresetPoolIndex value of 0 in the multi-TRP operation of multiple DCI schedules may be applied to the A-CSI-RS resources, and if one or more A-CSI-RS resources in the second A-CSI-RS resource set are not provided with any QCL information, then the second indicated joint / DL TCI state in the multi-TRP operation of a single DCI schedule or the indicated joint / DL TCI state specific to a coresetPoolIndex value of 1 in the multi-TRP operation of multiple DCI schedules may be applied to the A-CSI-RS resources.

[0140] In some aspects, one or more resource pairs may be configured in a CSI resource set via RRC configuration (e.g., cmrGroupingAndPairing-r17), where each resource pair includes two CSI-RS resources. If a first CSI-RS resource in the resource pair is not provided with any QCL information, a first indicated joint / DL TCI state may be applied to the CSI-RS resource, and if a second CSI-RS resource in the resource pair is not provided with any QCL information, a second indicated joint / DL TCI state is applied to the CSI-RS resource.

[0141] In some aspects, the UE 1020 may apply an indicated joint / DL TCI state specific to a coresetPoolIndex value to an A-CSI-RS resource set triggered by a PDCCH on a CORESET, where the coresetPoolIndex value is determined from a value associated with the CORESET. For example, the configuration may indicate that the UE 1020 is to apply a first unified TCI state to a single A-CSI-RS resource set or a second unified TCI state to the A-CSI-RS resource set based at least in part on a CORESET pool index value corresponding to the CORESET in which the DCI was received (e.g., in the PDCCH).

[0142] In some aspects, a coresetPoolIndex value may be configured per PUCCH resource or per PUCCH resource group, and the UE 1020 may apply an indicated joint / UL TCI state specific to the coresetPoolIndex value to the corresponding PUCCH transmission. In some aspects, an RRC configuration may be provided per PUCCH resource or per PUCCH resource group to indicate that the UE 1020 is to apply a first indicated joint / DL TCI state or a second indicated joint / UL TCI state to the corresponding PUCCH transmission, where the first indicated joint / DL TCI state and the second indicated joint / DL TCI state correspond to indicated joint / UL TCI states specific to coresetPoolIndex values ​​of 0 and 1, respectively. In some aspects, if the UE 1020 is not configured with joint acknowledgement (ACK) / negative acknowledgement (NACK) feedback for multi-TRP operation based on multiple DCIs (e.g., ackNackFeedbackMode=Joint), the UE 1020 may apply the indicated joint / UL TCI state specific to the coresetPoolIndex value to the PUCCH transmission triggered by the PDCCH on the CORESET, where the coresetPoolIndex value is determined from the value associated with the CORESET.

[0143] As indicated above, Figure 10 are provided as examples. Other examples can be found in the Figure 10 The examples described are different.

[0144] Figure 11 is a diagram illustrating an example 1100 of TCI state selection for PDSCH according to the present disclosure.

[0145] In some aspects, in a unified TCI framework extension for sDCI-based multiple TRPs, the network entity 1010 may (e.g., via RRC signaling) configure the UE 1020 to monitor and interpret a TCI selection field (e.g., 2 bits) that will be present in DCI formats 1_1 / 1_2 for scheduling and / or activating PDSCH reception (e.g., including dynamic PDSCH and semi-persistent scheduling (SPS) PDSCH).

[0146] Example 1100 illustrates the use of a 2-bit TCI selection field. As shown at 1105, the network entity 1010 may transmit an RRC message configuring the UE 1020 to use the 2-bit TCI state selection field. As shown at 1110, the network entity 1010 may transmit DCI with a codepoint in the two-bit TCI state selection field. As shown at 1115, the UE 1020 may apply a unified TCI state corresponding to the codepoint to the PDSCH DMRS port. As shown at 1120, the network entity 1010 may transmit PDSCH communications using the unified TCI state.

[0147] In some aspects, if the DCI format 1_1 / 1_2 indicates a code point of "00" for the TCI selection field, the UE 1020 may apply the first indicated joint / DL TCI state to all PDSCH DMRS ports for all PDSCH transmission opportunities scheduled and / or activated by the DCI format 1_1 / 1_2. If the DCI format 1_1 / 1_2 indicates a code point of "01" for the TCI selection field, the UE 1020 may apply the second indicated joint / DL TCI state to all PDSCH DMRS ports for all PDSCH transmission opportunities scheduled and / or activated by the DCI format 1_1 / 1_2. If the DCI format 1_1 / 1_2 indicates a code point of "10" for the TCI selection field, the UE 1020 may apply both the first indicated joint / DL TCI state and the second indicated joint / DL TCI state to PDSCH reception scheduled and / or activated by the DCI format 1_1 / 1_2.

[0148] In some aspects, for a PDSCH TDM scheme with two PDSCH opportunities, a PDSCH SDM scheme with two DMRS code division multiplexing (CDM) groups, or a PDSCH FDM scheme with two frequency domain resource allocations (FDRAs), 3GPP standard Release 16 mapping rules may be reused to map the first indicated joint / DLTCI state and the second indicated joint / DL TCI state to the PDSCH transmission opportunity, CDM group, or non-overlapping FDRA by replacing the first indicated joint / DL TCI state and the second indicated joint / DLTCI state with the first indicated joint / DL TCI state. For example, the UE 1020 may apply the first unified TCI state and the second unified TCI state to the first PDSCH opportunity, CDM group, or non-overlapping FDRA and the second PDSCH opportunity, CDM group, or non-overlapping FDRA in a first order based at least in part on the codepoint being a third codepoint value. UE 1020 may apply the first unified TCI state and the second unified TCI state to the first PDSCH opportunity, CDM group or non-overlapping FDRA and the second PDSCH opportunity, CDM group or non-overlapping FDRA in a second order opposite to the first order based at least in part on the code point being a fourth code point value.

[0149] For PDSCH SFN or CJT Tx schemes, the UE 1020 may apply both the first indicated joint / DL TCI state and the second indicated joint / DL TCI state to all PDSCH DMRS ports. If the DCI format 1_1 / 1_2 indicates the code point "11" for the TCI selection field, the code point may be a reserved code point. If the DCI format 1_1 / 1_2 indicates the code point "11" for the TCI selection field, the Release 16 mapping rules may be reused for the PDSCH TDM / SDM / FDM Tx scheme to map the second indicated joint / DL TCI state and the first indicated joint / DL TCI state to PDSCH transmission timing, CDM group, or non-overlapping FDRA. For example, the UE 1020 may apply the first unified TCI state and the second unified TCI state to the PDSCH DMRS port based at least in part on the code point being the third code point value. By using the code point in the TCI state selection field in the DCI, the A-CSI-RS may be more accurate and communication will be improved.

[0150] In some aspects, if the UE 1020 does not have an SFN scheme enabled for PDSCH (e.g., not indicated by the RRC parameter sfnSchemePdsch), the UE 1020 may apply the first indicated joint / DL TCI state to PDSCH reception scheduled or activated by DCI format 1_0 (including dynamically granted PDSCH and semi-persistently scheduled PDSCH). In some aspects, if the UE 1020 has an SFN scheme enabled for PDSCH (e.g., indicated by the RRC parameter sfnSchemePdsch), the UE 1020 may apply both the first indicated joint / DL TCI state and the second indicated joint / DL TCI state to PDSCH reception scheduled / activated by DCI format 1_0 (including dynamically granted PDSCH and semi-persistently scheduled PDSCH). In some aspects, the UE 1020 may apply the first indicated joint / UL TCI state to PUSCH transmissions scheduled / activated by DCI format 0_0 (including dynamically granted PUSCH and type 2 configured grant PUSCH).

[0151] As indicated above, Figure 11 are provided as examples. Other examples can be found in the Figure 11 The examples described are different.

[0152] Figure 12 is a diagram illustrating an example process 1200, performed, for example, by a UE, according to the present disclosure. Example process 1200 is an example in which a UE (eg, UE 120, UE 1020) performs operations associated with TCI state selection for A-CSI.

[0174] although Figure 12 Example blocks of process 1200 are shown, but in some aspects, process 1200 may include Figure 12 The blocks depicted may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted. Additionally or alternatively, two or more of the blocks of process 1200 may be performed in parallel.

[0175] Figure 13 is a diagram illustrating an example process 1300, for example, performed by a network entity, in accordance with the present disclosure. The example process 1300 is an example in which a network entity (eg, network node 110, network entity 1010) performs operations associated with TCI state selection for A-SCI.

[0176] like Figure 13 As shown, in some aspects, process 1300 may include sending a configuration for at least one A-CSI-RS resource set (block 1310). For example, a network entity (e.g., using Figure 17 The transmitting component 1704 and / or the communication manager 1706 depicted in may transmit a configuration for at least one A-CSI-RS resource set, as described above.

[0177] like Figure 13 As further shown, in some aspects, process 1300 may include sending an indication of the first unified TCI state and the second unified TCI state (block 1320). For example, a network entity (e.g., using Figure 17The sending component 1704 and / or the communication manager 1706 depicted in can send indications of the first unified TCI state and the second unified TCI state, as described above.

[0178] like Figure 13 As further shown, in some aspects, process 1300 may include sending a DCI that triggers an A-CSI state associated with the at least one A-CSI-RS resource set (block 1330).

[0186] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the at least one A-CSI-RS resource set includes only one A-CSI-RS resource set, and the CORESET pool index value in the configuration indicates that the UE is to apply a first unified TCI state to the one A-CSI-RS resource set or to apply a second unified TCI state to the one A-CSI-RS resource set.

[0187] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, the at least one A-CSI-RS resource set includes only one A-CSI-RS resource set, and the configuration indicates that the UE is to apply a first unified TCI state to the one A-CSI-RS resource set based at least in part on a CORESET pool index value of zero for the UE, and to apply a second unified TCI state to the one A-CSI-RS resource set based at least in part on a CORESET pool index value of one for the UE.

[0188] In a seventh aspect, alone or in combination with one or more of aspects 1 to 6, the at least one A-CSI-RS resource set includes only one A-CSI-RS resource set, and the configuration instructs the UE to apply a first unified TCI state to the one A-CSI-RS resource set or a second unified TCI state to the one A-CSI-RS resource set based at least in part on a CORESET pool index value corresponding to the CORESET in which the DCI is received.

[0189] although Figure 13 Example blocks of process 1300 are shown, but in some aspects, process 1300 may include Figure 13 The blocks depicted may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted. Additionally or alternatively, two or more of the blocks of process 1300 may be performed in parallel.

[0190] Figure 14 1 is a diagram illustrating an example process 1400, for example, performed by a UE, according to the present disclosure. Example process 1400 is an example in which a UE (eg, UE 120, UE 1020) performs operations associated with TCI state selection for a PDSCH.

[0191] like Figure 14 As shown, in some aspects, process 1400 may include receiving an RRC message that configures the UE to receive a two-bit TCI state selection field (block 1410). For example, a UE (e.g., using Figure 16 The receiving component 1602 and / or the communication manager 1606 depicted in can receive an RRC message that configures the UE to receive a two-bit TCI state selection field, as described above.

[0192] like Figure 14 As further shown, in some aspects, process 1400 may include receiving a DCI including a codepoint in the two-bit TCI state selection field (block 1420). For example, a UE (e.g., using Figure 16 The receiving component 1602 and / or the communication manager 1606 depicted in FIG. 1 may receive a DCI including a codepoint in the two-bit TCI state selection field, as described above.

[0193] like Figure 14 As further shown, in some aspects, process 1400 may include applying a unified TCI state corresponding to the code point to a PDSCH DMRS port for a PDSCH opportunity scheduled or activated by the DCI (block 1430). Figure 16The communication manager 1606 depicted in FIG) may apply the unified TCI state corresponding to the code point to the PDSCH DMRS ports of the PDSCH opportunities scheduled or activated by the DCI, as described above.

[0194] like Figure 14 As further shown, in some aspects, process 1400 may include receiving a PDSCH communication using the unified TCI state (block 1440). Figure 16 The receiving component 1602 and / or the communication manager 1606 depicted in FIG may use the unified TCI state to receive PDSCH communications, as described above.

[0195] Process 1400 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.
