Description

Background Art

[0001] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for coherent downlink channel operations.

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

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

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

[0040] A user equipment (UE) may communicate with multiple transmit receive points (TRPs) using beams. A TRP is a network entity configured to send and receive signals. For example, a TRP may include one or more components of a base station. A "beam" may refer to a directional transmission, such as a wireless signal sent in the direction of a receiving device. A beam may include a directional signal, a direction associated with the signal, a set of directional resources associated with the signal (e.g., angle of arrival, horizontal direction, vertical direction), and / or a set of parameters indicating one or more aspects of a directional signal, a direction associated with the signal, and / or a set of directional resources associated with the signal.

[0041] In some cases, the UE may communicate with multiple TRPs simultaneously (e.g., at the same time) according to a multi-TRP (mTRP) configuration. In an mTRP downlink communication, the UE may receive multiple communications, each from a different TRP. Each communication may be a spatial layer of a joint communication associated with a physical downlink shared channel (PDSCH). A joint communication is a communication that includes more than one signal that shares one or more time resources. Each TRP may be set at a different position from each other TRP, and therefore, each respective communication may be associated with one or more different respective spatial resources. Therefore, each respective communication may be a spatial layer of a joint communication. The spatial layer of a joint communication is a portion of the joint communication corresponding to a set of spatial resources. For example, a joint communication may include a first spatial layer corresponding to a first set of spatial resources and a second spatial layer corresponding to a second set of spatial resources.

[0042] In order to receive joint communications from multiple TRPs, a single wide beam corresponding to a single transmit configuration indicator (TCI) state may be used. However, the single wide beam may result in the application of a single spatial filter applied to all layers of the joint communications, which may not be coherent (e.g., the layers of the joint communications may not have corresponding phases such that the layers may be constructively combined at the receiving device). A spatial filter is a mechanism (e.g., a process, procedure, circuit, and / or software, etc.) for directing electromagnetic signals into a specific path. In some cases, a coherent joint transmit (CJT) configuration may be used for coherent joint communications to facilitate more efficient application of spatial filters, which may result in fewer lost signals and higher spectral efficiency.

[0043] The CJT configuration can be used for PDSCH communication, physical uplink control channel (PUCCH) communication and / or physical uplink shared channel (PUSCH) communication. CJT is a joint transmission in which each layer of the joint transmission is transmitted with a corresponding phase so that the layer can be constructively combined at the receiving device. In order to facilitate support for CJT for mTRP PDSCH and / or uplink channel communications, some aspects may provide for configuring a UE with multiple unified TCIs for CJT transmission. A unified TCI is a TCI that indicates a unified TCI state, which is a beam indication that can be used for multiple channels and / or signals simultaneously. In some aspects, for example, the UE may obtain configuration information associated with mTRP CJT PDSCH operation. mTRP CJT PDSCH operation refers to an operation in which the UE receives mTRP CJT via PDSCH.

[0044] For example, a TCI activation medium access control control element (MAC CE) indicating activation of a TCI code point having at least one unified TCI may be used to facilitate monitoring of a control resource set (CORESET) for physical downlink control channel (PDCCH) communications. The TCI code point may be a value of a TCI in a downlink control information (DCI) transmission. In some aspects, the unified TCI may be selected based on a flag (e.g., a binary field) indicating a radio resource control (RRC) configuration.

[0045] Some aspects can facilitate semi-persistent scheduling (SPS) PDSCH reception for CJT. SPS PDSCH reception refers to the reception of downlink signals in reception opportunities configured to repeat according to a configuration. For example, when a UE is configured with a quantity X of unified TCIs for each layer of CJT PDSCH in mTRP operation, for SPS PDSCH reception previously associated with a quantity Z of unified TCIs, the UE can apply all X new unified TCIs to the SPS PDSCH, regardless of the values of X and Z. In another example, the UE can ignore the X new TCIs and still apply the Z unified TCIs to the SPS PDSCH. In another example, the UE can apply the same quantity of TCIs (e.g., Z). For example, if Z < X, the UE can select Z TCIs (e.g., the first Z unified TCIs) from the X newly indicated TCIs for the SPS PDSCH. In another example, if Z > X, the UE can apply the Z old TCIs to the SPS PDSCH. In another example, the UE can apply a default TCI code point (e.g., the TCI code point with the lowest ID among the Z TCIs).

[0046] In some aspects, a UE can be configured to switch between a CJT communication scheme (e.g., a communication mode for sending and / or receiving CJT communications) and another type of communication scheme. For example, the UE can monitor the PDSCH based on a first communication scheme during a first time period and monitor the PDSCH based on a second communication scheme during a second time period based on meeting a handover condition. The first communication scheme or the second communication scheme can correspond to at least one of time division multiplexing (TDM) mTRP operation, space division multiplexing (SDM) mTRP operation, or single frequency network (SFN) operation. In some examples, the UE can be configured to switch communication schemes according to a handover based on RRC configuration and / or a handover based on MAC CE.

[0047] In this way, multiple beams (where each beam corresponds to a respective TCI) can be used to receive CJT PDSCH communications and / or send CJT PUCCH and / or PUSCH communications from multiple TRPs. Since each TRP is associated with a respective beam, each layer of CJT PDSCH communications can be associated with a unique spatial filter. Additionally, to facilitate CJT, in some aspects, each indicated unified TCI can be used to receive each layer of CJT PDSCH communications.

[0048] In some aspects, a related precoding scheme may be used to facilitate CJT mTRP PUSCH operation. CJT mTRPPUSCH operation is an operation in which a UE sends a CJT mTRP communication via a PUSCH. The precoding scheme may include a set of predecoders for precoding corresponding layers of a joint communication. In some cases, each layer may be precoded using the same predecoder as each other layer. However, due to spatial variations between layers, using the same predecoder for all layers may result in incoherent joint communications. In some aspects, a related precoding scheme may be used to facilitate the transmission of CJT. For example, each layer of a CJTPUSCH communication may be precoded using a corresponding predecoder that is configured so that the layers of the CJT communication can be transmitted coherently.

[0049] In this manner, some aspects may facilitate single DCI-based CJT for mTRP operation and may therefore improve throughput and / or spectral efficiency, thereby positively impacting network performance.

[0050] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method.

[0051] Aspects and examples generally include methods, apparatus, network nodes, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication devices, and / or processing systems as described or fully described herein with reference to the figures and description and as illustrated in the figures and description.

[0052] The present disclosure can be easily used as a basis for modifying or designing other structures for the same purpose of performing the present disclosure. Such equivalent constructions do not depart from the scope of the appended claims. When considered in conjunction with the accompanying drawings, the characteristics of the concepts disclosed herein (both their organization and method of operation) and the associated advantages are better understood from the following description. Each of the figures in the accompanying drawings is provided for the purpose of illustration and description, not as a definition of the limitations of the claims.

[0053] Although various aspects are described in the present disclosure by illustrating some examples, such aspects can be implemented in many different arrangements and scenarios. The technology described herein can be implemented using different platform types, devices, systems, shapes, sizes and / or packaging arrangements. For example, some aspects can be implemented via integrated chip implementations or other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / shopping equipment, medical equipment and / or artificial intelligence devices). Various aspects can be implemented in chip-level components, modular components, non-modular components, non-chip-level components, device-level components and / or system-level components. The equipment incorporating the various aspects and features described may include additional components and features for implementing and practicing the various aspects claimed and described. For example, the transmission and reception of wireless signals may include one or more components (e.g., hardware components, including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders and / or summers) for analog and digital purposes. Various aspects described herein can be practiced in various devices, components, systems, distributed arrangements and / or end-user devices of different sizes, shapes and compositions.

[0054] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0055] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).

[0056] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one UE 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0057] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a TRP, a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.

[0058] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0059] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with the network node 110). In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of 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 the other. In this way, a single device may include more than one base station.

[0060] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communications between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0061] 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).

[0062] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link. In some aspects, the network controller 130 may be, or may include, a CU or a core network device.

[0063] UE 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.

[0064] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0065] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0066] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0067] The electromagnetic spectrum is typically subdivided by frequency / wavelength into various categories, bands, channels, etc. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, 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 different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0068] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF band.

[0069] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0070] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive configuration information associated with mTRP CJT PDSCH operation, wherein the configuration information indicates one or more unified TCIs; and receive CJT communications including multiple transmission layers based on the one or more unified TCIs, wherein each transmission layer in the multiple transmission layers corresponds to each unified TCI in the one or more unified TCIs.

[0071] In some aspects, the communication manager 140 may receive configuration information associated with mTRP CJT physical uplink channel operation; generate a layer of CJT communication, wherein the layer of the CJT communication is based on a related precoding scheme associated with a plurality of TRPs; and send the layer of the CJT communication to the plurality of TRPs. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0072] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send configuration information associated with mTRP CJT PDSCH operation, wherein the configuration information indicates one or more unified TCIs; and send CJT communications including multiple transmission layers based on the one or more unified TCIs, wherein each transmission layer in the multiple transmission layers corresponds to each unified TCI in the one or more unified TCIs.

[0073] In some aspects, the communication manager 150 may send configuration information associated with mTRP CJT physical uplink channel operation; and receive a layer of CJT communication, wherein the layer of the CJT communication is based on a related precoding scheme associated with a plurality of TRPs, and wherein the network node includes a TRP in the plurality of TRPs. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0074] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0075] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0076] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or 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 (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).

[0077] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0078] 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.

[0079] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or antennas coupled to one or more transmit and / or receive components (such as antennas). Figure 2 One or more antenna elements of one or more components in.

[0080] Each of the antenna elements may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element that is cross-polarized with a second sub-element, which can be used to independently transmit cross-polarized signals. The antenna elements may include patch antennas, dipole antennas, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements may allow signals having a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam). For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half wavelength, or other fraction of a wavelength of the spacing between adjacent antenna elements to allow interaction or interference of signals transmitted by individual antenna elements within the desired range.

[0081] Antenna elements and / or sub-elements may be used to generate beams. A "beam" may refer to a directional transmission, such as a wireless signal transmitted in the direction of a receiving device. A beam may include a directional signal, a direction associated with the signal, a set of directional resources associated with the signal (e.g., angle of arrival, horizontal direction, vertical direction), and / or a set of parameters indicating one or more aspects of a directional signal, a direction associated with the signal, and / or a set of directional resources associated with the signal.

[0082] As indicated above, antenna elements and / or sub-elements can be used to generate beams. For example, antenna elements can be individually selected or deselected for transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers. Beamforming includes generating beams using multiple signals on different antenna elements, wherein one or more or all of the multiple signals are shifted in phase relative to each other. The formed beams can carry physical or higher layer reference signals or information. When each of the multiple signals is radiated from the corresponding antenna element, the radiated signals interact, interfere (constructively and destructively) and amplify with each other to form the resulting beam. The shape (such as amplitude, width and / or the presence of side lobes) and direction (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shift or phase offset of the multiple signals relative to each other.

[0083] Beamforming may be used for communication between a UE and a base station, such as for millimeter wave communication, etc. In such a case, the base station may provide the UE with a configuration of a TCI state, each of which indicates a beam that may be used by the UE, such as for receiving a PDSCH. The base station may indicate an activated TCI state to the UE, and the UE may use the activated TCI state to select a beam for receiving a PDSCH.

[0084] The beam indication may be or include a TCI state information element, a beam identifier (ID), spatial relationship information, a TCI state ID, a closed loop index, a panel ID, a TRP ID, and / or a sounding reference signal (SRS) set ID, etc. The TCI state information element (referred to herein as TCI state) may indicate information associated with a beam such as a downlink beam. For example, the TCI state information element may indicate a TCI state identifier (e.g., tci-StateID), a quasi-co-location (QCL) type (e.g., qcl-Type1, qcl-Type2, qcl-TypeA, qcl-TypeB, qcl-TypeC, qcl-TypeD, etc.), a cell identifier (e.g., ServCellIndex), a bandwidth part identifier (bwp-Id), a reference signal identifier (such as CSI-RS (e.g., NZP-CSI-RS-ResourceId, SSB-Index, etc.)), etc. The spatial relationship information may similarly indicate information associated with an uplink beam.

[0085] The beam indication may be a joint or separate downlink (DL) / uplink (UL) beam indication in a unified TCI framework. In some cases, the network may use at least UE-specific (unicast) downlink control information (DCI) to indicate a joint or separate DL / UL beam indication from an active TCI state, thereby supporting beam indication based on layer 1 (L1). In some cases, existing DCI formats 1_1 and / or 1_2 may be reused for beam indication. The network may include a support mechanism for the UE to confirm successful decoding of the beam indication. For example, an acknowledgment / negative acknowledgment (ACK / NACK) of a PDSCH scheduled by a DCI carrying a beam indication may also be used as an ACK for the DCI.

[0086] Beam indication may be provided for carrier aggregation (CA) scenarios. In a unified TCI framework, the network may support common TCI state ID updates and activations to provide common QCL information and / or one or more common UL transmit spatial filters across a set of configured component carriers (CCs). This type of beam indication may be applicable to intra-band CA as well as joint DL / UL beam indication and separate DL / UL beam indication. A common TCI state ID may mean that a reference signal (RS) determined according to a TCI state indicated by a common TCI state ID is used to provide a QCL type D indication and determine a UL transmit spatial filter across a set of configured CCs.

[0087] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0088] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of an antenna 234, a modem 232, a MIMO detector 236, a receive processor 238, a transmit processor 220, and / or a TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0089] In some aspects, the controller / processor 280 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be communicated to other systems or components, such as the UE 120. For example, the processing system of the UE 120 may be a system that includes various other components or subcomponents of the UE 120.

[0090] The processing system of UE 120 may interface with one or more other components of UE 120, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of UE 120 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that UE 120 may receive information or signal input, and may pass information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that UE 120 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0091] In some aspects, controller / processor 240 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be passed to other systems or components, such as network node 110. For example, a processing system of network node 110 may be a system that includes various other components or subcomponents of network node 110.

[0092] The processing system of the network node 110 may interface with one or more other components of the network node 110, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of the network node 110 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that the network node 110 may receive information or signal input, and may pass information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that the network node 110 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0093] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the network node 110 may perform one or more techniques associated with coherent downlink channel operations, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 6 The process of 600 Figure 7 The process of 700 Figure 8 The process of 800 Fig. 9 900 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 6 The process of 600 Figure 7 The process of 700 Figure 8 The process of 800 Fig. 9 The process 900 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0094] In some aspects, UE 120 includes: a component for receiving configuration information associated with mTRP CJT PDSCH operation, wherein the configuration information indicates one or more unified TCIs; and / or a component for receiving CJT communications including multiple transmission layers based on one or more unified TCIs, wherein each transmission layer in the multiple transmission layers corresponds to each unified TCI in the one or more unified TCIs.

[0095] In some aspects, the UE 120 includes: means for receiving configuration information associated with mTRP CJT physical uplink channel operation; means for generating a layer of CJT communication, wherein the layer of the CJT communication is based on a related precoding scheme associated with multiple TRPs; and / or means for sending a layer of CJT communication to multiple TRPs. Means for the UE to perform operations described herein may include, for example, one or more of the following: the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0096] In some aspects, the network node 110 includes: a component for sending configuration information associated with mTRP CJT PDSCH operation, wherein the configuration information indicates one or more unified TCIs; and / or a component for sending CJT communications including multiple transmission layers based on one or more unified TCIs, wherein each transmission layer in the multiple transmission layers corresponds to each unified TCI in the one or more unified TCIs. The components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0097] In some aspects, the network node 110 includes: a component for sending configuration information associated with mTRP CJT physical uplink channel operation; and / or a component for receiving a layer of CJT communication, wherein the layer of the CJT communication is based on a related precoding scheme associated with multiple TRPs, and wherein the network node includes a TRP in the multiple TRPs.

[0098] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0099] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0100] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0101] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of 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), and the like.

[0102] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0103] Figure 3 3 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated 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 disaggregated control units, such as a near-RT RIC 325 via an E2 link, or a non-RTRIC 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 RF access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0104] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces, the one or more interfaces being configured to receive or send signals, data, or information (collectively referred to as 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 a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.

[0105] 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, etc. 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 specific 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.

[0106] 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 MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 3GPP. In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may further host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0107] Each RU 340 may implement lower 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 lower 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).

[0108] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an 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 an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTRIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an 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.

[0109] The non-RT RIC 315 may be configured to include logic functions that enable 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 may be coupled to or communicate with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as 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.

[0110] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function 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 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0111] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0112] Figure 4A 4 is a diagram illustrating an example 400 of mTRP communication (sometimes referred to as multi-panel communication) according to the present disclosure. Figure 4A As shown in FIG. 4 , UE 402 may communicate with multiple TRPs 404. A network node (eg, network node 110) may include multiple TRPs 404, or multiple TRPs 404 may be distributed across multiple network nodes.

[0113] Multiple TRPs 404 (shown as TRP A, TRP B, TRP C, and TRP D) may communicate with the same UE 402 in a coordinated manner (e.g., using coordinated multipoint transmission) to improve reliability and / or increase throughput. TRPs 404 may coordinate such communications via interfaces between TRPs 404 (e.g., backhaul interfaces and / or access node controllers). When TRPs 404 are co-located at the same network node (e.g., when TRPs 404 are different antenna arrays or panels of the same network node), the interface may have less latency and / or higher capacity, and when TRPs 404 are located at different network nodes, the interface may have greater latency and / or lower capacity (compared to co-location). Different TRPs 404 may communicate with UE 402 using different QCL relationships (e.g., different TCI states), different DMRS ports, and / or different layers (e.g., different layers in multi-layer communications).

[0114] In some cases, a single physical downlink control channel (PDCCH) 406 may be used to schedule downlink data communications for a single PDSCH 408. In some cases, the PDCCH 406 may be used to schedule a PUSCH 410. In some cases, multiple TRPs 404 (e.g., TRP A and TRP B) may send communications to a UE 402 on the same PDSCH 408. For example, a joint communication may be sent using a single codeword with different spatial layers for different TRPs 404 (e.g., where one codeword is mapped to a first set of layers sent by a first TRP 404 and is mapped to a second set of layers sent by a second TRP 404). As another example, communications may be sent using multiple codewords, where different codewords are sent by different TRPs 404 (e.g., using different sets of layers). In either case, different TRPs 404 may use different QCL relationships (e.g., different TCI states) for different DMRS ports corresponding to different layers. For example, the first TRP 404 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 404 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, the TCI field may indicate a single TCI state (for a single TRP transmission) or multiple TCI states (for multi-TRP transmission as discussed herein).

[0115] For mTRP PDSCH transmissions, in some cases, a single TCI state may be used for all TRPs 404. In this case, for example, to receive joint communications from TRP A, TRP B, TRP C, and TRP D, a wide beam 412 corresponding to a single TCI state may be used. However, a single wide beam may result in the application of filters applied to all TRPs 404 (and therefore to the layers of the communication), which may not be coherent between TRPs. In some cases, a CJT configuration may be used to facilitate a more efficient application of spatial filters, which may result in fewer lost signals and more spectral efficiency.

[0116] Some aspects of the techniques and apparatus described herein may provide for configuring a UE with multiple unified TCIs for a PDSCH, thereby enabling single-DCI-based CJT for an mTRP PDSCH. Figure 4B 4 is a diagram illustrating an example 414 of mTRP CJT communication according to the present disclosure. Figure 4B As shown in , for example, a network node (e.g., TRP A 404) may send configuration information 416, and UE 402 may receive the configuration information. Configuration information 416 may be associated with mTRP CJT PDSCH operation. Configuration information 416 may indicate one or more unified TCIs, each of which may correspond to a TRP 404 in a plurality of TRPs 404. In this manner, multiple beams 418 (where each beam 418 corresponds to a respective TCI) may be used to receive CJT PDSCH communications at an mTRP. Since each TRP 404 is associated with a respective beam 418, each layer 420 (shown as "layer 0" and "layer 1") of a CJT PDSCH communication 422 may be associated with a unique spatial filter. In some aspects, a coherent precoding scheme may be used to facilitate CJT mTRP PUSCH operation. In this manner, some aspects may facilitate single DCI-based CJT for mTRP operation and may therefore improve throughput and / or spectral efficiency, thereby positively impacting network performance.

[0117] In some aspects, for example, to implement single DCI-based CJT for mTRP operation, the UE 402 may be indicated with up to X unified TCIs for the PDSCH, where each layer and / or DMRS antenna port of the PDSCH is received using a plurality of the indicated unified TCIs. For example, as shown, layer 0 may be received using each of TCI 0, TCI 1, TCI 2, and TCI 3, and layer 1 may be received using each of TCI 0, TCI 1, TCI 2, and TCI 3. In some aspects, the configuration information 416 may include a TCI activation medium access control (MAC) control element (CE) (MAC CE), where a TCI code point may be activated using up to X joint TCIs, up to X downlink TCIs, or up to X unified TCIs, where each unified TCI may be a joint TCI or a downlink TCI. In some aspects, the maximum value of X for CJT PDSCH may be a UE capability (e.g., X=4). In some aspects, each TCI may be associated with a corresponding coherent per-TRP downlink pre-decoder.

[0118] In aspects where multiple (X>1) unified TCIs for each layer of the CJT PDSCH are used to indicate the UE 402 in the mTRP operation, to receive the PDCCH in the control resource set (CORESET) 424, the UE 402 may perform a first operation, where the UE 402 may select one TCI for the corresponding CORESET 424. For example, the UE 402 may select the first TCI among the X unified TCIs, or may select a TCI based on the RRC label included in the TCI. In some aspects, the UE 402 may perform a second operation instead of the first operation, where the UE 402 may apply all the unified TCIs to PDCCH reception. In a third operation, the UE 402 may perform the first operation or the second operation based on the RRC configuration 'CJTforPDCCH' for the corresponding CORESET 424 or for all CORESETS. In a fourth operation, if the corresponding CORESET 424 is not configured to share the indicated unified TCI, the UE 402 may apply a separately indicated TCI.

[0119] In some aspects, when the UE 402 is indicated with X unified TCIs for each layer of the CJT PDSCH in the mTRP operation, for semi-persistent scheduling (SPS) PDSCH reception that was previously applied with Z unified TCIs, the UE 402 may apply all the new X unified TCIs to the SPS PDSCH, regardless of the values of X and Z, ignore the new X TCIs and still apply the old Z unified TCIs to the SPS PDSCH, or maintain the same number of TCIs for the SPS PDSCH. In the latter aspects, if Z < X, the UE 402 may select Z TCIs (e.g., the first Z unified TCIs) from the X newly indicated TCIs for the SPS PDSCH, and if Z > X, the UE 402 may apply the old Z TCIs to the SPS PDSCH. In some aspects, the UE 402 may apply a default TCI code point (e.g., the TCI code point with the lowest ID among the Z TCIs).

[0120] In some aspects, the configuration information 416 may facilitate switching between CJT and another mTRP scheme. Other mTRP schemes may include time division multiplexing (TDM), space division multiplexing (SDM), or single frequency network (SFN) for PDSCH. The switch may include a switch based on RRC configuration or a switch based on MAC CE activation, in which only one mTRP scheme (CJT / TDM / SDM / SFN) may be enabled by RRC. Two mTRP schemes may be enabled by RRC, for example, both CJT and SDM may be configured for enhanced mobile broadband (EMBB) services, and one may be selected by MAC CE. For example, in some aspects, an additional bit may be included in the TCI activation MAC CE to indicate whether CJT or other mTRP schemes are applied when two TCIs are activated for a TCI code point. In some aspects, if >2 TCIs are activated for a TCI code point, CJT may be applied; otherwise, other mTRP schemes may be applied.

[0121] In some aspects, the UE 402 may be configured with CJT for PUSCH / PUCCH, where layers of PUSCH / PUCCH may be coherently pre-coded across multiple TRPs 404. In FR1, in some aspects, the UE 402 may be indicated with multiple downlink TCIs for the downlink only, and no TCI may be applied to the uplink CJT. If supported, the per-TRP power control parameters may be linked to a per-TRP SRS resource indicator (SRI) indication. In some aspects, the UE 402 may be indicated with up to Y unified TCIs (e.g., joint or uplink TCIs) for uplink CJT. The joint or uplink TCI may provide power control settings (received power target (Po), closed loop index and / or fractional power control factor (α)) and path loss reference signal indicator for per-TRP power control associated with the corresponding TRP 404, and the UE 402 may ignore the QCL information in the TCI.

[0122] For FR2, the UE 402 may be indicated by up to Y joint or uplink TCIs for PUSCH / PUCCH. The maximum value of Y TCIs / per TRP power control for CJT may be the UE capability. For example, Y may be 2 or 4, and for Y>2, the number of closed-loop indexes may need to be increased. When unified TCI for uplink is supported, the UE 402 may be indicated by X downlink TCIs for downlink CJT and Y uplink TCIs for uplink CJT. In some aspects, the UE 402 may be indicated by Y joint TCIs for downlink and / or uplink and an additional XY downlink TCIs for downlink CJT. In some aspects, the UE 402 may be indicated by X joint TCIs for both downlink and uplink CJT. When UE 402 supports only Y per-TRP power control indications for uplink, but indicates with X>Y joint TCIs for downlink, UE 402 may select Y of the X joint TCIs for uplink CJT, or expect only Y of the X joint TCIs to have power control parameters.

[0123] As indicated above, Figure 4A and Figure 4B are provided as examples. Other examples can be found in the Figure 4A and Figure 4B The examples described are different.

[0124] Figure 5 5 is a diagram illustrating an example 500 associated with coherent downlink channel operations according to the present disclosure. As shown, the example 500 may include a UE 502 and a network node 504 communicating with each other. The network node 504 may include any number of TRPs (shown as "TRP A", "TRP B", "TRP C", and "TRP D"). The TRPs may be co-located and / or distributed. In some aspects, as shown, the network node 504 may include TRP A, TRP B, TRP C, and TRP D. In some other aspects, one or more of TRP A, TRP B, TRP C, and TRP D may be in a different location from the network node 504, and in some cases, may be independent of the network node 504. The UE 502 may be, be similar to, include, or be included in: Figure 4A and Figure 4B UE 402 as depicted in , and / or Figures 1 to 3 The network node 504 may be, be similar to, include, or be included in: the TRP 404 depicted in FIG. 4, Figure 1 and Figure 2The network node 110 depicted in FIG. 1 , and / or Figure 3 One or more components of the decomposed base station architecture 300 depicted in FIG.

[0125] As indicated by reference numeral 506, the network node 504 may send configuration information and the UE 502 may receive the configuration information. In some aspects, the configuration information may be associated with mTRP CJT PDSCH operation. The configuration information may indicate one or more unified TCIs. In some aspects, the configuration information may include an RRC configuration configured to facilitate mTRP CJT PDSCH operation and / or any other type of configuration or indication.

[0126] As shown in reference numeral 508, the network node 504 may send a TCI activation MAC CE, and the UE 502 may receive the TCI activation MAC CE. The TCI activation MAC CE may include an activation indicator corresponding to at least one code point mapped to at least one TCI state in a plurality of TCI states. For example, the TCI activation MAC CE may indicate that the TCI code point is activated using at least one TCI in one or more unified TCIs. In some aspects, the at least one code point includes a single code point. In some aspects, the mTRP configuration may include a TCI activation MAC CE. In some aspects, in order to support code points mapped to multiple TCI states, the UE 502 may be configured with a channel state information (CSI) report to report one or more pairs of beams that may be received or transmitted simultaneously.

[0127] In some aspects, the at least one TCI may include at least one of a joint TCI or a downlink TCI. In some aspects, the number of at least one TCI may be less than or equal to the maximum number of TCIs. In some aspects, the UE 502 may send UE capability information indicating the maximum number of TCIs, and the network node 504 may receive the UE capability information.

[0128] As shown by reference numeral 510, the UE 502 may monitor a CORESET for PDCCH communication based on at least one unified TCI of one or more unified TCIs. The at least one unified TCI may include a first TCI of a plurality of unified TCIs. For example, the UE 502 may select a first TCI of a plurality of unified TCIs. In some aspects, the at least one unified TCI may be based on an RRC flag indicated by the at least one unified TCI. In some aspects, the at least one unified TCI may include each unified TCI of the one or more unified TCIs. In some aspects, the configuration information may indicate at least one unified TCI of a control resource set CORESET for monitoring PDCCH communication in the one or more unified TCIs, and the UE 502 may monitor the CORESET based on at least one indicated TCI other than the at least one unified TCI based on the CORESET being configured to be monitored independently of the at least one unified TCI (e.g., based on the CORESET not being configured to share the at least one unified TCI).

[0129] As shown in reference numeral 512, network node 504 may send one or more DCI transmissions, and UE 502 may receive one or more DCI transmissions. In some aspects, the mTRP configuration may correspond to a single downlink control information (sDCI) operation. In some aspects, for example, the mTRP configuration may include a TCI mapping, which includes a TCI state activation field that maps a corresponding TCI state to a reference TCI code point in the DCI transmission. In some aspects, the mapping between the TCI state and the TCI code point may be indicated by a higher layer signaling such as a TCI activation MAC CE. For example, the TCI activation MAC CE may activate multiple TCI code points, and the DCI may indicate to the UE 502 a TCI code point selected from multiple TCI code points.

[0130] As shown by reference numeral 514, the network node 504 (e.g., via two or more of TRP A, TRP B, TRP C, or TRP D) may send CJT communications, and the UE 502 may receive the CJT communications. Based on one or more unified TCIs, the network node 504 may send CJT communications, and the UE 502 may receive CJT communications. The CJT communications may include multiple transmission layers. Each transmission layer in the multiple transmission layers may correspond to each TCI in the one or more unified TCIs.

[0131] In some aspects, based on sending or receiving a first SPS PDSCH communication, respectively, the network node 504 may send a CJT communication, and the UE 502 may receive the CJT communication. One or more unified TCIs may include a first set of TCIs consisting of a first number of TCIs. The network node 504 may send additional configuration information indicating a second set of TCIs for mTRP CJT PDSCH operation, and the UE 502 may receive additional configuration information indicating a second set of TCIs for mTRP CJT PDSCH operation. The second set of TCIs may consist of a second number of TCIs. In some aspects, the network node 504 may send a second SPS PDSCH communication based on the second set of TCIs, and the UE 502 may receive a second SPS PDSCH communication based on the second set of TCIs. In some aspects, the network node 504 may send a second SPS PDSCH communication based on the first set of TCIs, and the UE 502 may receive a second SPS PDSCH communication based on the first set of TCIs.

[0132] In some aspects, the network node 504 may send a second SPS PDSCH communication based on a third set of TCIs, and the UE 502 may receive a second SPS PDSCH communication based on the third set of TCIs, wherein the third set of TCIs consists of a first number of TCIs. In some aspects, based on the first number being less than or equal to the second number, the third set of TCIs may include a subset of the second set of TCIs, wherein the subset of the second set of TCIs consists of the first number of TCIs. In some aspects, the third set of TCIs may include a first set of TCIs based on the first number being greater than the second number. In some aspects, the UE 502 may receive a second SPS PDSCH communication based on a default TCI code point.

[0133] In some aspects, the UE 502 may receive CJT communications based on monitoring the PDSCH for a period of time. For example, the UE 502 may monitor the PDSCH based on a first communication scheme during a first time period, and monitor the PDSCH based on a second communication scheme during a second time period based on satisfying a switching condition. The first communication scheme or the second communication scheme may correspond to mTRP CJTPDSCH operation, and the other of the first communication scheme or the second communication scheme may correspond to at least one of TDM mTRP operation, SDM mTRP operation, or SFN operation.

[0134] In some aspects, UE 502 may be configured with CJT for uplink communications, such as PUSCH communications and / or PUCCH communications. Layers of PUSCH and / or PUCCH communications may be coherently precoded across multiple TRPs. As indicated by reference numeral 516, UE 502 may generate layers of CJT communications. The layers of CJT communications may be based on coherent precoding schemes associated with multiple TRPs. One or more other UEs may generate one or more additional layers of CJT communications.

[0135] As shown by reference numeral 518, the UE 502 may send layers of CJT communications, and the network node 504 may receive layers of CJT communications. In some aspects, the network node 504 may send indications of multiple SRIs, and the UE 502 may receive indications of multiple SRIs. Each SRI in the multiple SRIs may correspond to a TRP in the multiple TRPs. In order to send the layers of CJT communications, the UE 502 may be configured to send the layers of CJT communications based on multiple sets of power control parameters, wherein each set of the multiple sets of power control parameters is associated with an SRI in the multiple SRIs. In some aspects, the configuration information may indicate a first set of unified TCIs for mTRP CJT physical uplink channel operations. The first set of unified TCIs may include at least one of a joint TCI or an uplink TCI.

[0136] In some aspects, the first set of unified TCIs may indicate multiple sets of power control parameters. In some aspects, UE 502 may send UE capability information indicating a maximum value. The maximum value may correspond to the maximum number of TCIs or the maximum number of power control parameter sets. The number of the first set of unified TCIs may be less than or equal to the maximum value. In some aspects, the configuration information may also indicate a second set of unified TCIs for mTRP CJT physical downlink channel operation, wherein the number of unified TCIs in the second set of unified TCIs is less than or equal to the difference between the maximum value and the number of unified TCIs in the first set of unified TCIs.

[0137] As indicated above, Figure 5 are provided as examples. Other examples can be found in relation to Figure 5 The examples described are different.
