Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for mapping transmit-receive point identifiers to simultaneous uplink transmission components for multiple transmit-receive points. Background Art

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

[0003] A wireless network may include one or more base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications 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. The 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 using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink, using 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, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. 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

[0026] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art.

[0028] The present disclosure may be readily used as a basis for modifying or designing other structures for carrying out the same purpose of the present disclosure. Such equivalent constructions do not depart from the scope of protection of the appended claims. The characteristics of the concepts disclosed herein, both in their organization and method of operation, and the associated advantages are better understood by considering the following description in conjunction with the accompanying drawings. Each of the figures in the accompanying drawings is provided for the purpose of illustration and description and not as a definition of the limitations of the claims.

[0029] 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 / purchasing 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.

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 purposes 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.

[0030] 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.

[0031] 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 applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0032] 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, etc. 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 base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d), a user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. The base station 110 is an entity that communicates with the UE 120. The base station 110 (sometimes referred to as a BS) 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, and / or a transmit receive point (TRP). Each base station 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 ​​a base station 110 and / or a base station subsystem serving the coverage area, depending on the context in which the term is used.

[0033] The base station 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 base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or a home base station. In Figure 1 In the example shown in , BS 110a may be a macro base station for macro cell 102a, BS 110b may be a pico base station for pico cell 102b, and BS 110c may be a femto base station for femto cell 102c. A base station may support one or more (eg, three) cells.

[0034] In some examples, the cell may not necessarily be fixed, and the geographic area of ​​the cell may move according to the location of the mobile base station 110 (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected with each other and / or to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0035] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a base station 110 or a UE 120) and transmit the transmissions of data to a downstream station (e.g., a UE 120 or a base station 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 FIG. 1 , BS 110d (eg, a relay base station) may communicate with BS 110a (eg, a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. Base station 110 that relays communication may be referred to as a relay station, relay base station, relay, or the like.

[0036] The wireless network 100 may be a heterogeneous network that includes different types of base stations 110, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 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 base station may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0037] A network controller 130 may be coupled to or in communication with a set of base stations 110 and may provide coordination and control for the base stations 110. The network controller 130 may communicate with the base stations 110 via backhaul communication links. The base stations 110 may communicate with each other directly or indirectly via wireless or wired backhaul communication links.

[0038] UE 120 can be dispersed throughout the wireless network 100, and each UE 120 can be fixed or mobile. UE 120 can include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 can 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, and / or any other suitable device configured to communicate via a wireless medium.

[0039] 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, which may communicate with a base station, 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 in 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 operationally coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0040] 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. RAT may be referred to as a radio technology, an air interface, etc. Frequency may be referred to as a carrier, a 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, a NR network or a 5G RAT network may be deployed.

[0041] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more side link channels (e.g., without using base station 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., the vehicle-to-everything (V2X) protocols 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 base station 110.

[0042] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency 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 a "below 6 GHz" band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as a "millimeter wave" band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU).

[0043] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0044] In view of the above examples, unless otherwise specifically stated, it should be understood that where the term "below 6 GHz" or the like is used herein, the term can be broadly referred to as frequencies that can be below 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that where the term "millimeter wave" or the like is used herein, the term can be broadly referred to as frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or can 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) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0045] As described herein, a network node may also be referred to as a "node" or a "wireless node", and may be a base station (e.g., base station 110), a UE (e.g., UE 120), a relay device, a network controller, an apparatus, a device, a computing system, one or more components of any of these, and / or another processing entity configured to perform one or more aspects of the techniques described herein. For example, a network node may be a UE. For another example, a network node may be a base station. A network node may be one or more components of a converged base station and / or a decomposed base station. For example, a first network node may be configured to communicate with a second network node or a third network node. The adjectives "first", "second", "third", etc. are used to contextually distinguish between two or more of the modified nouns in conjunction with a discussion, and are not meant to be absolute modifiers that apply only to a corresponding node in the entire document. For example, a network node may be referred to as a "first network node" in conjunction with one discussion, and may be referred to as a "second network node" in conjunction with another discussion, and vice versa. References to UEs, base stations, apparatuses, devices, computing systems, etc. may include disclosure of UEs, base stations, apparatuses, devices, computing systems, etc. as network nodes. For example, the disclosure that the UE is configured to receive information from the base station also discloses that the first network node is configured to receive information from the second network node. Consistent with the present disclosure, once a specific example is expanded according to the present disclosure (e.g., the UE is configured to receive information from the base station also discloses that the first network node is configured to receive information from the second network node), the broader example of the narrower example can be interpreted in reverse, but in a broad, open-ended manner. In the above example where the UE is configured to receive information from the base station also discloses that the first network node is configured to receive information from the second network node, "first network node" may refer to a first UE, a first base station, a first device, a first equipment, a first computing system, a first one or more components, a first processing entity, etc. configured to receive information from the second network; and "second network node" may refer to a second UE, a second base station, a second device, a second equipment, a second computing system, a second one or more components, a second processing entity, etc.

[0046] In some aspects, UE 120 may include communication manager 140. As described in more detail elsewhere herein, communication manager 140 may receive an uplink repetition configuration from a network node associated with a first TRP identifier (ID) and a second TRP ID, the uplink repetition configuration including a first mapping between the first TRP ID and a first uplink repetition component and a second mapping between the second TRP ID and a second uplink repetition component; send a first uplink transmission corresponding to the first TRP ID based at least in part on the first mapping; and send a second uplink transmission corresponding to the second TRP ID based at least in part on the second mapping. Additionally or alternatively, communication manager 140 may perform one or more other operations described herein.

[0047] In some aspects, the network node may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may transmit an uplink repetition configuration including a first mapping between a first TRP ID and a first uplink repetition component and a second mapping between a second TRP ID and a second uplink repetition component; receive a first uplink transmission corresponding to the first TRP ID based at least in part on the first mapping; and receive a second uplink transmission corresponding to the second TRP ID based at least in part on the second mapping. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0048] As indicated above, Figure 1 Other examples can be found in the Figure 1 The examples described are different.

[0049] Figure 2 2 is a diagram illustrating an example 200 of base station 110 communicating with UE 120 in wireless network 100 according to the present disclosure. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T ≥ 1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R ≥ 1).

[0050] At the base station 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQI) received from the UE 120. The base station 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 partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-decoding) 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 modulators) (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 further process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0051] In some aspects, the terms "base station" (e.g., base station 110), "network node" or "network entity" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, and / or one or more components thereof. For example, in some aspects, a "base station", "network node" or "network entity" may refer to a central unit (CU), a distributed unit (DU), a radio unit (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 terms "base station", "network node" or "network entity" may refer to one device configured to perform one or more functions, such as those described herein in conjunction with base station 110. In some aspects, the terms "base station", "network node" or "network entity" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the performance of at least a portion of the function, and the terms "base station", "network node", or "network entity" may refer to any one or more of those different devices. In some aspects, the terms "base station", "network node", or "network entity" may refer to one or more virtual base stations and / 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 terms "base station", "network node", or "network entity" may refer to one of the base station functions, but not another base station function. In this way, a single device may include more than one base station.

[0052] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the base station 110 and / or other base stations 110, and a set of received signals (e.g., R received signals) may be provided 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 (RS SI) 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.

[0053] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0054] 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. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0055] 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 a cross-polarized signal. 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 be such that signals having a desired wavelength transmitted individually by the antenna elements may 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.

[0056] Antenna elements and / or sub-elements may be used to generate beams. A "beam" may specify a wireless signal that is transmitted in a direction, such as 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.

[0057] 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.

[0058] Beamforming may be used for communication between a UE and a base station, such as for millimeter wave communication, etc. In this case, the base station may provide the UE with a configuration of a transmit configuration indicator (TCI) state, which respectively indicates beams that may be used by the UE, such as for receiving a physical downlink shared channel (PDSCH). The base station may indicate the activated TCI state to the UE, and the UE may use the activated TCI state to select a beam for receiving the PDSCH.

[0059] The beam indication may be or include a TCI state information element, a beam 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.

[0060] 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 11 and / or 12 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 ACK / NACK (ACK / NACK) for a PDSCH scheduled by a DCI carrying a beam indication may also be used as an ACK for the DCI. The wireless communication system may support the use of various types of unified TCI. For example, a first type of unified TCI (e.g., type 1 TCI) may be used to indicate a common beam for at least one downlink channel or reference signal and for at least one uplink channel or reference signal (e.g., a joint downlink uplink common TCI state). A second type of unified TCI (e.g., type 2TCI) may be used to indicate a common beam for more than one downlink channel or reference signal (e.g., a separate downlink common TCI state). A third type of unified TCI (e.g., type 3TCI) may be used to indicate a common beam for more than one uplink channel or reference signal (e.g., a separate uplink common TCI state). A fourth type of unified TCI (e.g., type 4TCI) may be used to indicate a beam for a single downlink channel or reference signal (e.g., a separate downlink single channel or reference signal TCI). A fifth type of unified TCI (e.g., type 5TCI) may be used to indicate a beam for a single uplink channel or reference signal (e.g., a separate uplink single channel or reference signal TCI). A sixth type of unified TCI (e.g., type 6TCI) may include uplink spatial relationship information to indicate a beam for a single uplink channel or reference signal.

[0061] Beam indication may be provided for carrier aggregation (CA) scenarios. In a unified TCI framework, the network may support information for common TCI state ID updates and activations to provide common QCL 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.

[0062] 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 transmitted to the base station 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 the functions described herein (eg, with reference to Figures 7 to 11 ) any aspects of any of the methods described herein.

[0063] At the base station 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 of the modem 232, shown as DEMOD), 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 base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the base station 110 may include a modulator and a demodulator. In some examples, the base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 7 to 11 ) or any aspect of any of the methods described herein.

[0064] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of may perform one or more techniques associated with mapping TRP IDs to simultaneous uplink transmission components for multiple TRPs, as described in more detail elsewhere herein. In some aspects, the network node described herein is Figure 2 The base station 110 is shown, is included in the base station 110, or includes one or more components of the base station 110. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the 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 base station 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium that stores one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly executed, or executed after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example 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.

[0065] In some aspects, a UE includes: a component for receiving an uplink repetition configuration from a network node associated with a first TRP ID and a second TRP ID, the uplink repetition configuration including a first mapping between the first TRP ID and a first uplink repetition component and a second mapping between the second TRP ID and a second uplink repetition component; a component for sending a first uplink transmission corresponding to the first TRP ID based at least in part on the first mapping; and / or a component for sending a second uplink transmission corresponding to the second TRP ID based at least in part on the second mapping. The components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0066] In some aspects, a network node includes a component for transmitting an uplink repetition configuration, the uplink repetition configuration including a first mapping between a first TRP ID and a first uplink repetition component and a second mapping between a second TRP ID and a second uplink repetition component; a component for receiving a first uplink transmission corresponding to the first TRP ID based at least in part on the first mapping; and / or a component for receiving a second uplink transmission corresponding to the second TRP ID based at least in part on the second mapping. In some aspects, 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.

[0067] 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 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.

[0068] As indicated above, Figure 2 Other examples can be found in the Figure 2 The examples described are different.

[0069] Figure 3 is a diagram illustrating an example 300 of a disaggregated base station architecture according to the present disclosure.

[0070] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts 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 or a network equipment (such as a base station (BS, e.g., base station 110), or one or more units (or one or more components) performing base station functionality can be implemented in an aggregated architecture or a decomposed architecture. For example, a BS (such as a Node B (NB), an eNB, an NRBS, a 5G NB, an access point (AP), a TRP, a cell, etc.) can be implemented as an aggregated base station (also called a stand-alone BS or a monolithic BS) or a decomposed base station.

[0071] The aggregated base station can be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. The decomposed base station can be configured to utilize a protocol stack 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 aspects, the CU can be implemented within a RAN node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed in one or more other RAN nodes. The DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual unit, namely a virtual centralized unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0072] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an IAB network, an O-RAN (such as a network configuration sponsored by the O-RAN Alliance), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Various units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0073] Figure 3 The decomposed base station architecture shown may include one or more CUs 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with a core network 320 through one or more decomposed base station units, such as a near-RT RIC 325 via an E2 link, or 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 corresponding midhaul links, such as an F1 interface. The DU 330 may communicate with one or more RUs 340 via corresponding fronthaul links. The RU 340 may communicate with corresponding UEs 120 via one or more RF access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0074] Each of the units (e.g., CU 310, DU 330, RU 340), as well as the near-RT RIC 325, the non-RTRIC 315, and the SMO framework 305 may include one or more interfaces, or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired transmission medium or a wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interface of the unit may be configured to communicate with one or more of the other units via a transmission medium. For example, the unit may include a wired interface that is configured to receive or send signals to one or more of the other units on a wired transmission medium. Additionally, the unit may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) that is configured to receive or send signals, or both, to one or more of the other units on a wireless transmission medium.

[0075] In some aspects, CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by CU 310. CU310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP)), control plane functionality (e.g., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU310 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, CU 310 may be implemented to communicate with DU 330 for network control and signaling.

[0076] DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RU340. In some aspects, DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) depending at least in part on functional splits such as those defined by 3GPP. In some aspects, DU 330 may also host one or more low PHY layers. Each layer (or module) may be implemented with an interface that is configured to communicate signals with other layers (and modules) hosted by DU 330 or with control functions hosted by CU 310.

[0077] The lower layer functionality may be implemented by one or more RUs 340. In some deployments, a RU 340 controlled by a DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional split (such as a lower layer functional split). In such an architecture, the RU 340 may be implemented to handle over-the-air (OTA) communications with one or more UEs 120. In some 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 the implementation of the DU 330 and the CU 310 in a cloud-based RAN architecture (such as a vRAN architecture).

[0078] 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) 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, and near-RT RIC 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 specific implementations, the SMO framework 305 may communicate directly with one or more RUs 340 via the O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305 .

[0079] The non-RT RIC 315 may be configured to include logic functions that implement 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 implement 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.

[0080] 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 O1) or via creation of RAN management policies (such as A1 policies).

[0081] As indicated above, Figure 3 Other examples can be found in the Figure 3 The examples described are different.

[0082] Figure 4 is a diagram illustrating example 400 of multi-TRP operation according to the present disclosure.

[0083] like Figure 4As shown in , in multi-TRP operation, the UE may communicate with a first TRP (TRP A) and a second TRP (TRP B). The first TRP may be associated with a first TCI state or a first QCL. The second TRP may be associated with a second TCI state or a second QCL. The UE may use time division multiplexing (TDM) to perform uplink transmissions to the first TRP and the second TRP. The UE may use TDM cyclic mapping to perform uplink transmissions to the first TRP and the second TRP, wherein the UE may alternate between performing uplink transmissions to the first TRP and uplink transmissions to the second TRP. For example, the UE may perform a first uplink transmission to the first TRP, a second uplink transmission to the second TRP, a third uplink transmission to the first TRP, and a fourth uplink transmission to the second TRP. The UE may use TDM sequential mapping to perform uplink transmissions to the first TRP and the second TRP, wherein the UE may first perform a set of uplink transmissions to the first TRP, and then perform a set of uplink transmissions to the second TRP. For example, the UE may perform a first uplink transmission and a second uplink transmission to a first TRP, and then the UE may perform a third uplink transmission and a fourth uplink transmission to a second TRP.

[0084] As indicated above, Figure 4 Other examples can be found in the Figure 4 The examples described are different.

[0085] Figure 5 is a diagram illustrating example 500 of multi-TRP operation according to the present disclosure.

[0086] As shown by reference numeral 502, in multi-TRP operation, the UE may support single-DCI multi-TRP PDSCH transmission or physical uplink shared channel (PUSCH) transmission. In a first example, a first transmission associated with a first TRP (e.g., a first TCI state or a first QCL) may be spatially divided multiplexed (SDM) with a second transmission associated with a second TRP (e.g., a second TCI state or a second QCL). The first transmission and the second transmission may be associated with different spatial layers, but may overlap in time and / or frequency. In a second example, the first transmission may be frequency-division multiplexed (FDM) with the second transmission. The first transmission and the second transmission may be simultaneous transmissions and may overlap in time but not in frequency. In a third example, the first transmission may be TDM with the second transmission. The first transmission and the second transmission may be non-simultaneous transmissions. The first transmission and the second transmission may overlap in frequency but not in time.

[0087] As indicated by reference numeral 504, in multi-TRP operation, the UE may support multi-DCI (multi-DCI) multi-TRP (multi-TRP) PDSCH transmission or PUSCH transmission. A first transmission associated with a first TRP may be frequency division multiplexed with a second transmission associated with a second TRP. The first transmission and the second transmission may be associated with separate DMRS.

[0088] As indicated above, Figure 5 Other examples can be found in the Figure 5 The examples described are different.

[0089] Figure 6 is a diagram illustrating example 600 of multi-TRP operation according to the present disclosure.

[0090] As shown by reference numeral 602, in multi-TRP operation, the UE may support DCI repetition. The UE may communicate with a first TRP and a second TRP, wherein the first TRP may be associated with a first control resource set (CORESET) and / or aggregation level (AL), and the second TRP may be associated with a second CORESET and / or AL. As shown by reference numeral 604, in multi-TRP operation, the UE may support physical uplink control channel (PUCCH) or PUSCH repetition, which may be based at least in part on TDM. As shown by reference numeral 606, in multi-TRP operation, the UE may support single frequency network (SFN) physical downlink control channel (PDCCH) transmission and / or PDSCH transmission, which may be associated with the same time / frequency resources (or same layer) but different beams.

[0091] As indicated above, Figure 6 Other examples can be found in the Figure 6 The examples described are different.

[0092] In some cases, unified TCI may be extended to multi-TRP (mTRP) scenarios, which may include simultaneous uplink transmissions. Simultaneous uplink transmissions are two or more uplink transmissions that occur simultaneously or during respective time periods that at least partially overlap.

[0093] In some cases, the wireless communication standard may specify TDM-based PUSCH repetitions using beam scanning across repetitions (which may include nominal repetitions, such as, for example, in PUSCH repetition type B). When two SRS resource sets are configured, the mapping of each SRS resource indicator (SRI) and the corresponding uplink beam to each repetition can be determined based on the associated SRS resource set for each repetition. For example, in the first case, mapping may be defined for PUSCH repetition types A and B scheduled and / or activated by DCI. In the first case, when the SRS resource set indicator in the downlink control information (DCI) scheduling the PUSCH is 00, the first SRS resource set of multiple configured SRS resource sets is associated with all repetitions of the PUSCH, wherein the predecoder for the PUSCH is derived based on the first SRS resource set. In the case where the SRS resource set indicator in the DCI for scheduling the PUSCH is 01, the second SRS resource set in the plurality of SRS resource sets is associated with all repetitions of the PUSCH, wherein the predecoder for the PUSCH is derived based on the second SRS resource set. In the case where the SRS resource set indicator in the DCI for scheduling the PUSCH is 10 and the number of repetitions is 2, the first SRS resource set and the second SRS resource set are associated with the first repetition and the second repetition of the PUSCH, respectively, wherein the predecoder for the first repetition of the PUSCH and the predecoder for the second repetition of the PUSCH are derived based on the first SRS resource set and the second SRS resource set, respectively. In the case where the SRS resource set indicator in the DCI scheduling PUSCH is 10 and the number of repetitions is greater than 2, in the case where the higher layer parameter cyclicMapping is enabled, the mapping pattern is defined as follows: the first PUSCH repetition is associated with the first SRS resource set, the second PUSCH repetition is associated with the second SRS resource set, the third PUSCH repetition is associated with the first SRS resource set, the fourth PUSCH repetition is associated with the second SRS resource set, etc., and in the case where the higher layer parameter sequentialMapping is enabled, the mapping pattern is defined as follows: the first PUSCH repetition is associated with the first SRS resource set, the second PUSCH repetition is associated with the first SRS resource set, the third PUSCH repetition is associated with the second SRS resource set, the fourth PUSCH repetition is associated with the second SRS resource set, etc. In the case where the SRS resource set indicator in the DCI scheduling PUSCH is 11, the same rules applicable to the case where the SRS resource indicator is 10 apply, except that the first SRS resource set and the second SRS resource set are swapped for different PUSCH repetitions.

[0094] In the second case, mapping may be defined for PUSCH repetitions configured by RRC, such as, for example, a grant (CG) of type 1 configuration. In the second case, in the case where a single SRS resource set indicator is provided, the first SRS resource set is associated with all repetitions of the PUSCH. In the case where two SRS resource set indicators are provided and the number of repetitions is 2, the first SRS resource set and the second SRS resource set are associated with the first repetition and the second repetition of the PUSCH, respectively. In the case where the number of repetitions is greater than two and the higher layer parameter cyclicMapping is enabled, the mapping pattern is defined as follows: the first PUSCH repetition is associated with the first SRS resource set, the second PUSCH repetition is associated with the second SRS resource set, the third PUSCH repetition is associated with the first SRS resource set, the fourth PUSCH repetition is associated with the second SRS resource set, and so on. When the higher layer parameter sequentialMapping is enabled, the mapping mode is defined as follows: the first PUSCH repetition is associated with the first SRS resource set, the second PUSCH repetition is associated with the first SRS resource set, the third PUSCH repetition is associated with the second SRS resource set, the fourth PUSCH repetition is associated with the second SRS resource set, and so on.

[0095] In some cases, TDM-based PUCCH repetition with beam scanning across repetitions is supported. In those cases, when a single PUCCH resource is used for repetitions with two beams (e.g., two configured spatial filter settings), in the case where the number of repetitions is 2, the first spatial setting and the second spatial setting are associated with the first repetition and the second repetition, respectively. In the case where the number of repetitions is greater than 2 and cyclicMapping is enabled, the mapping mode is defined as follows: the first PUCCH repetition is associated with the first beam, the second PUCCH repetition is associated with the second beam, the third PUCCH repetition is associated with the first beam, the fourth PUCCH repetition is associated with the second beam, and so on. Otherwise, the mapping mode is defined as follows: the first PUCCH repetition is associated with the first beam, the second PUCCH repetition is associated with the first beam, the third PUCCH repetition is associated with the second beam, the fourth PUCCH repetition is associated with the second beam, and so on.

[0096] The above mapping can be useful in single TRP and mTRP settings to facilitate mapping of SRS resources to different beams. However, in some cases, the unified TCI of each TRP is not mapped to each uplink repetition of multiple FDM repetitions and / or SDM repetitions. Therefore, a UE using the above mapping may be limited to non-simultaneous uplink transmissions in an mTRP scenario, thereby reducing potential network and resource efficiency.

[0097] Some aspects of the techniques and apparatus described herein may facilitate simultaneous uplink transmissions to two or more TRPs. Although described with respect to simultaneous uplink transmissions to two TRPs, some aspects described herein may be equally applicable to three or more TRPs. In some aspects, a UE may receive an uplink repetition configuration from a network node associated with a first TRP ID and a second TRP ID, the uplink repetition configuration comprising a first mapping between a first TRP ID and a first uplink repetition component and a second mapping between a second TRP ID and a second uplink repetition component. The UE may send a first uplink transmission corresponding to the first TRP ID based at least in part on the first mapping, and send a second uplink transmission corresponding to the second TRP ID based at least in part on the second mapping. In this way, some aspects may facilitate simultaneous uplink transmissions associated with two or more TRP IDs, thereby increasing network and / or resource efficiency, and thus positively affecting network and / or device performance.

[0098] Figure 7 is a diagram illustrating an example 700 associated with mapping transmit-receive point identifiers to simultaneous uplink transmit components for multiple transmit-receive points according to the present disclosure. Figure 7 As shown in , example 700 includes wireless communications between a UE 702 and a network node 704. The network node 704 can be a plurality of TRPs, include a plurality of TRPs, or be included in a plurality of TRPs. For example, in some aspects, a first TRP ID and a second TRP ID can be associated with the network node 704. In some aspects, the network node 704 can represent a plurality of network nodes, each of the plurality of network nodes having an associated TRP ID.

[0099] As shown by reference numeral 706, network node 704 may send an uplink repetition configuration, and UE 702 may receive the uplink repetition configuration. The uplink repetition configuration may include a first mapping between a first SRS resource set and a first uplink repetition component and a second mapping between a second SRS resource set and a second uplink repetition component. The first mapping may be based at least in part on a mapping between the first SRS resource set and the first uplink repetition component, and the second mapping may be based at least in part on a mapping between the second SRS resource set and the second uplink repetition component. In some aspects, the first mapping may correspond to an association between a first precoding indication indicated by a first transmit precoding matrix index (TPMI) and / or a first SRI corresponding to a first SRS resource set and a first uplink repetition component. The second mapping may correspond to an association between a second TPMI indication and / or a second SRI corresponding to a second SRS resource set and a second uplink repetition component.

[0100] In some aspects, the first mapping may be further based at least in part on a mapping between a first TRP ID and a first SRS resource set, and the second mapping may be based at least in part on a mapping between a second TRP ID and a second SRS resource set. For example, the first mapping may correspond to an association between a first TCI state associated with the first TRP ID and a first uplink repetition component, and the second mapping may correspond to an association between a second TCI state associated with the second TRP ID and a second uplink repetition component. The first TCI state and the second TCI state may be a pair of uplink applicable TCI states in a TCI code point indicated by a DCI or activated by a MAC-CE. The uplink applicable TCI state may be an uplink TCI or a joint TCI. In some aspects, the first TRP ID may include at least one of the following: a first CORESET pool index, a first TCI state, a first beam group ID, a first channel, a first reference signal, a first resource group ID, or a first TCI order index, and wherein the second TRP ID includes at least one of the following: a second CORESET pool index, a second TCI state, a second beam group ID, a second channel, a second reference signal, a second resource group ID, or a second TCI order index.

[0101] In some aspects, for example, the mapping between uplink beams and corresponding repetitions may be based on an SRS resource set indicator for simultaneous PUSCH transmission in an mTRP scenario. In some examples, each SRS resource set may be mapped to a PUSCH repetition component of an FDM or SDM. In this way, the TPMI and / or SRI indication associated with a given SRS resource set may be applied to the corresponding PUSCH repetition component for uplink MIMO precoding determination. Each TRP ID may be mapped to an SRS resource set so that the uplink or joint TCI state associated with a given TRP ID may be applied to the corresponding PUSCH repetition component for uplink beam indication and power control parameters. As indicated above, the TRP ID may be indicated by the following: CORESETPoolIndex, TCI group ID, beam group ID, channel group ID, reference signal group ID, resource group ID, and / or a TCI order index among all TCIs mapped to the selected TCI code point. For example, the first selected uplink applicable TCI may be mapped to a first TRP, such as TRP ID=1, and the second selected uplink applicable TCI may be mapped to a second TRP, such as TRP ID=2, where the order index of the two selected TCIs may be predefined. The first selected uplink applicable TCI and the second selected uplink applicable TCI may correspond to a pair of TCIs in a TCI code point through specific beam indication signaling (such as DCI).

[0102] In some aspects, as described below, with respect to three different cases (referred to as "Case 1", "Case 2", and "Case 3", respectively), the mapping of each SRS resource set to each FDM or SDM uplink repetition can be based on an SRS resource set indicator. In some aspects, the operating parameters (e.g., TPMI, TCI, and / or power control, etc.) for each uplink repetition can be determined by the SRI and TRP ID indication associated with the corresponding SRS resource set, as described above.

[0103] In case 1, the repetition configuration corresponds to the simultaneous transmission of an SDM-based uplink shared channel (e.g., PUSCH) scheduled and / or activated by a DCI. For example, the DCI may schedule mTRP PUSCH transmission using two DMRS code division multiplexing (CDM) groups that may be indicated in the scheduling DCI. The first uplink repetition component refers to the PUSCH repetition using the first DMRS CDM group indicated by the antenna port indication for the DMRS in the DCI, and the second uplink repetition component refers to the PUSCH repetition using the second DMRS CDM group indicated by the antenna port indication for the DMRS in the DCI. The first uplink repetition component and the second uplink repetition component may be transmitted in different spatial layer sets. In some aspects, the DCI may include an SRS resource set indicator having a value of a plurality of values ​​indicating a mapping between at least one SRS resource set and at least one of the first uplink repetition component or the second uplink repetition component. The first SRS resource set may be associated with the first uplink repetition component and the second uplink repetition component based at least in part on the value of the SRS resource set indicator being the first value (e.g., 00) among multiple values. The second SRS resource set may be associated with the first uplink repetition component and the second uplink repetition component based at least in part on the value of the SRS resource set indicator being the second value (e.g., 0 1) among multiple values. The first SRS resource set may be associated with the first uplink repetition component and the second SRS resource set may be associated with the second uplink repetition component based at least in part on the value of the SRS resource set indicator being the third value (e.g., 10) among multiple values. The first SRS resource set may be associated with the second uplink repetition component and the second SRS resource set may be associated with the first uplink repetition component based at least in part on the value of the SRS resource set indicator being the fourth value (e.g., 11) among multiple values. For example, where the SRS resource set indicator has a fourth value, the SRS resource set mapping may be similar to the SRS resource set mapping associated with the third value, but wherein the first SRS resource set and the second SRS resource set are swapped when associating different uplink repetition components.

[0104] In case 2, the repetition configuration may correspond to simultaneous transmission of an FDM-based uplink shared channel (e.g., PUSCH) scheduled and / or activated by a DCI. The DCI may be, for example, a single DCI that schedules mTRP FDM-based PUSCH transmission, wherein a DMRS CDM group is indicated in the scheduling DCI. The scheduling DCI may allocate multiple resource blocks for scheduled FDM-based mTRP PUSCH transmission. In some aspects, a mapping between two uplink repetition components and two frequency allocations may be defined. In some aspects, a first frequency allocation may correspond to the first half of the resource blocks in a plurality of allocated resource blocks, and a second frequency allocation may correspond to the second half of the resource blocks in a plurality of allocated resource blocks. In some aspects, the first half of the resource blocks in a plurality of resource blocks may be associated with a first codeword using a first redundant version corresponding to a transport block, and the second half of the resource blocks in a plurality of resource blocks may be associated with a second codeword using a second redundant version corresponding to a transport block. In some aspects, the first codeword and the second codeword may be the same, while in some other aspects, the first codeword and the second codeword may be different codewords. In some aspects, the first half of the resource blocks in the plurality of resource blocks may include a set of resource blocks having even-numbered resource block IDs or having even-numbered resource block group IDs, and the second half of the resource blocks in the plurality of resource blocks may include a set of resource blocks having odd-numbered resource block IDs or having odd-numbered resource block group IDs. In some aspects, the DCI may indicate a frequency allocation mapping. For example, in some aspects, the network node 704 may explicitly or implicitly indicate which mapping is to be applied. The first uplink repetition component refers to a PUSCH repetition allocated using a first frequency, and the second uplink repetition component refers to a PUSCH repetition allocated using a second frequency. Any number of different parameter values ​​for different parameters may be used as an implicit indication. The mapping of each SRS resource set to each uplink component may be based on an SRS resource set indicator, as in case 1 above.

[0105] In case 3, the repetition configuration may correspond to a simultaneous transmission of an uplink shared channel based on SDM or FDM configured by RRC signaling (e.g., a type 1 CG transmission). In some aspects, for example, a first SRS resource set among multiple SRS resource sets may be associated with a first uplink repetition component and a second uplink repetition component based at least in part on a single SRI indication in RRC signaling. In some aspects, a first SRS resource set among multiple SRS resource sets may be associated with a first uplink repetition component and a second SRS resource set based at least in part on a first SRI indication associated with the first SRS resource set and a second SRI indication associated with the second SRS resource set in the multiple SRS resource sets in RRC signaling.

[0106] In some aspects, instead of mapping a TRP ID to an SRS resource set, the repetition configuration may map the TRP ID, and therefore, the corresponding uplink or joint TCI state directly to each corresponding PUSCH repetition component in a simultaneous SDM or FDM-based PUSCH transmission. For example, in the above cases 1, 2, and 3, the first TRP ID and the second TRP ID may be mapped to the first uplink applicable TCI and the second uplink applicable TCI, and the first uplink applicable TCI and the second uplink applicable TCI may be mapped to the first PUSCH repetition component and the second PUSCH repetition component, respectively. For example, in the above cases 1, 2, and 3, the first SRS resource set and the second SRS resource set may be replaced by the first TRP ID and the second TRP ID, respectively, where the SRS resource set indicator may be reused or replaced by a new field (e.g., TRP and / or TCI set ID) to indicate whether a single uplink beam or two uplink beams are to be applied. The TCI applicable to the first uplink and the TCI applicable to the second uplink may correspond to a pair of TCIs in a TCI code point through specific beam indication signaling (such as DCI).

[0107] In some aspects, for example, the first mapping may include a direct mapping between a first TRP ID and a first uplink repetition component, and the second mapping may include a direct mapping between a second TRP ID and a second uplink repetition component. In some aspects, the beam indicator may indicate the number of uplink beams associated with the first uplink repetition component and the second uplink repetition component. In some aspects, the first uplink transmission and the second uplink transmission may be TDM.

[0108] As shown by reference numeral 708, based at least in part on the first mapping, UE 702 may send a first uplink transmission corresponding to the first TRPID, and network node 704 (e.g., a first TRP associated with network node 704) may receive the first uplink transmission corresponding to the first TRP ID. As shown by reference numeral 710, based at least in part on the second mapping, UE 702 may send a second uplink transmission corresponding to the second TRP ID, and network node 704 (e.g., a second TRP associated with network node 704) may receive the second uplink transmission corresponding to the second TRP ID. In some aspects, as described above, the first uplink transmission and the second uplink transmission may be simultaneous uplink transmissions.

[0109] In some aspects, the repetition configuration may correspond to simultaneous transmission of an uplink control channel (e.g., PUCCH) based on SDM or FDM, where the TRP ID, and therefore the corresponding uplink or joint TCI state, may be directly mapped to each PUCCH repetition component. The first TCI may be mapped to the first PUCCH repetition component, and the second TCI may be mapped to the second PUCCH repetition component. The first PUCCH repetition component and the second PUCCH repetition component may be multiplexed using at least one of SDM or FDM. In some aspects, when the first PUCCH repetition component and the second PUCCH repetition component may be multiplexed using FDM, a mapping between two PUCCH repetition components and two frequency allocations of PUCCH resources may be defined. In some aspects, the first frequency allocation may correspond to the first half of the resource blocks in a plurality of allocated resource blocks for PUCCH resources, and the second frequency allocation may correspond to the second half of the resource blocks in a plurality of allocated resource blocks for PUCCH resources. In some other aspects, the first frequency allocation may correspond to a set of odd-numbered resource blocks or resource block groups of a plurality of resource blocks allocated to the PUCCH resources, and the second frequency allocation may correspond to a set of even-numbered resource blocks or resource block groups of a plurality of resource blocks allocated to the PUCCH resources. In some aspects, when SDM may be used to multiplex the first PUCCH repetition component and the second PUCCH repetition component, the first PUCCH repetition component and the second PUCCH repetition component may be mapped to two PUCH repetitions using a first DMRS CDM group and a second DMRS CDM group of the PUCCH resources.

[0110] As indicated by reference numeral 712, UE 702 may transmit a first uplink shared channel transmission corresponding to a first uplink shared channel component and network node 704 may receive the first uplink shared channel transmission corresponding to the first uplink shared channel component, and as indicated by reference numeral 714, UE 702 may transmit a second uplink shared channel transmission corresponding to a second uplink shared channel component and network node 704 may receive the second uplink shared channel transmission corresponding to the second uplink shared channel component. In some aspects, the first uplink shared channel component may correspond to a first frequency allocation and the second uplink shared channel component may correspond to a second frequency allocation different from the first frequency allocation.

[0111] In some aspects, for example, the first frequency allocation may correspond to the first half of the resource blocks in the plurality of resource blocks, and the second frequency allocation may correspond to the second half of the resource blocks in the plurality of resource blocks. The first half of the resource blocks in the plurality of resource blocks may include a set of resource blocks with even resource block IDs, and the second half of the resource blocks in the plurality of resource blocks may include a set of resource blocks with odd resource block IDs. In some aspects, the first uplink shared channel component may correspond to the first CDM group, and the second uplink shared channel component may correspond to the second CDM group. In some aspects, the first uplink control channel component may correspond to the first CDM group, and the second uplink control channel component may correspond to the second CDM group. The first mapping may correspond to a first rule indicated by a wireless communication standard, and the second mapping may correspond to a second rule indicated by the wireless communication standard.

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

[0113] Figure 8 800 is a diagram illustrating an example process 800 performed, for example, by a UE according to the present disclosure. Example process 800 is an example in which a UE (e.g., UE 702) performs operations associated with mapping TRP IDs to simultaneous uplink transmission components for multiple TRPs.

[0114] like Figure 8 As shown in , in some aspects, process 800 may include receiving an uplink repetition configuration from a network node associated with a first TRP ID and a second TRP ID, the uplink repetition configuration including a first mapping between the first TRP ID and a first uplink repetition component and a second mapping between the second TRP ID and a second uplink repetition component (block 810). For example, a UE (e.g., using Fig.10 The communication manager 1008 and / or receiving component 1002 depicted in the figure may receive an uplink repetition configuration from a network node associated with the TRPID and the second TRP ID, as described above, the uplink repetition configuration including a first mapping between the first TRP ID and the first uplink repetition component and a second mapping between the second TRP ID and the second uplink repetition component.

[0115] like Figure 8 As further shown in FIG. 8 , in some aspects, process 800 may include sending a first uplink transmission corresponding to a first TRP ID based at least in part on the first mapping (block 820). For example, a UE (e.g., using Fig.10The communication manager 1008 and / or the sending component 1004 depicted in the figure may send a first uplink transmission corresponding to the first TRP ID based at least in part on the first mapping, as described above.

[0116] like Figure 8 As further shown in FIG. 8 , in some aspects, process 800 may include sending a second uplink transmission corresponding to a second TRP ID based at least in part on the second mapping (block 830).
