Description

Technical Field

[0001] Broadly speaking, aspects of the present disclosure relate to wireless communication and relate to techniques and apparatus for multiple uplink configurations for multiple antenna panel transmissions. Background Art

[0002] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple access technology capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / Advanced LTE is an enhanced set of the universal mobile telecommunications system (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0003] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). A user equipment (UE) may communicate with a base station (BS) via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0004] The above multiple access techniques have been adopted in various telecommunication standards to provide a common protocol that enables different user equipments to communicate at the urban, national, regional, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhanced set of the LTE mobile standard released by the 3rd Generation Partnership Project (3GPP). NR is designed to better integrate with other open standards by improving spectral efficiency, reducing costs, enhancing services, leveraging new spectrums, and using Orthogonal Frequency Division Multiplexing with Cyclic Prefix (CP-OFDM) on the downlink (DL), and CP-OFDM and / or SC-FDM (e.g., also referred to as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technology, and carrier aggregation, so as to better support mobile broadband Internet access. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0023] The various aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of any other aspect of the present disclosure or in combination with any other aspect. For example, an apparatus may be implemented using any number of the aspects set forth herein or a method may be implemented. Additionally, the scope of the present disclosure is intended to cover such an apparatus or method implemented using other structures, functions, or a combination of structures and functions in addition to or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of a claim.

[0024] Certain aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description through various boxes, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"), and are illustrated in the accompanying drawings. These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0025] It should be noted that although terms typically associated with 5G or NR radio access technology (RAT) may be used herein to describe aspects, the aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RAT (e.g., 6G).

[0026] Figure 1FIG. is a schematic diagram illustrating an example of a wireless network 100 in accordance with various aspects of the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network, an LTE network, etc. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographical area. In 3GPP, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0027] The BS may provide communication coverage for macro cells, picocells, femtocells, and / or another type of cell. A macro cell may cover a relatively large geographical area (e.g., with a radius of several kilometers) and may allow unrestricted access by UEs with a service subscription. A picocell may cover a relatively small geographical area and may allow unrestricted access by UEs with a service subscription. A femtocell may cover a relatively small geographical area (e.g., a residence) and may allow restricted access by UEs associated with the femtocell (e.g., UEs in a closed subscriber group (CSG)). The BS for a macro cell may be referred to as a macro BS. The BS for a picocell may be referred to as a pico BS. The BS for a femtocell may be referred to as a femto BS or a home BS. In Figure 1 the example shown, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for picocell 102b, and BS 110c may be a femto BS for femtocell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0028] In some aspects, a cell may not necessarily be stationary, and the geographical area of a cell may move according to the location of a mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (e.g., direct physical connections, virtual networks, and / or similar interfaces using any suitable transport network).

[0029] The wireless network 100 may also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send the data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. In Figure 1 the example shown in, the relay station 110d can communicate with the macro BS 110a and the UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station can also be referred to as a relay BS, a relay base station, a relay, etc.

[0030] The wireless network 100 can be a heterogeneous network that includes different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS can have a high transmit power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0031] The network controller 130 can be coupled to a set of BSs and can provide coordination and control for these BSs. The network controller 130 can communicate with the BSs via a backhaul. The BSs can also communicate with each other directly or indirectly, e.g., via a wireless or wired backhaul.

[0032] UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, a terminal, a mobile station, a user unit, a station, etc. A UE 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 device, a camera, a gaming device, a netbook, a smartbook, a superbook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio unit), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0033] Some UEs can be considered as Machine Type Communication (MTC) or evolved or enhanced Machine Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node can provide a connection to or from a network (e.g., a wide area network such as the Internet or a cellular network) via, for example, a wired or wireless communication link. Some UEs can be considered as Internet of Things (IoT) devices, and / or can be implemented as NarrowBand IoT (NB-IoT) devices. Some UEs can be considered as Customer Premises Equipment (CPE). The UE 120 can be included inside a housing that houses components of the UE 120 such as a processor component, a memory component, etc. In some aspects, the processor component and the memory component can be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., a memory) can be operatively coupled, communicatively coupled, electronically coupled, electrically coupled, etc.

[0034] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. The RAT can also be referred to as a radio technology, an air interface, etc. The frequency can also be referred to as a carrier, a channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0035] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using the base station 110 as an intermediary for communicating with each other). For example, the UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which can include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), a mesh network, etc. In such cases, the UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0036] As noted above, Figure 1 is provided as an example. Other examples can be different from the examples regarding Figure 1 described.

[0037] Figure 2FIG. 200 is a schematic diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 in accordance with various aspects of the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where generally T≥1 and R≥1.

[0038] At the base station 110, a transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCSs) for the UE at least in part based on channel quality indicators (CQIs) received from each UE, process (e.g., encode and modulate) the data for the UE at least in part based on the MCSs selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRSs), demodulation reference signals (DMRSs), etc.) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable), and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process the corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from the modulators 232a through 232t may be transmitted via the T antennas 234a through 234t, respectively. In accordance with various aspects described in more detail below, synchronization signals may be generated using position coding to convey additional information.

[0039] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide the received signals to demodulators (DEMOD) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0040] 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.

[0041] 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 reporting including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded (if applicable) by the TX MIMO processor 266, further processed by the modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as described with reference to Figure 5 、 6A 、6B、7, and 8).

[0042] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 can include communication unit 244 and communicate with network controller 130 via communication unit 244. In some aspects, base station 110 includes a transceiver. The transceiver can include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any method described herein (e.g., as described with reference to Figure 5 , 6A , 6B, 7, and 8).

[0043] Controller / processor 240 of base station 110, controller / processor 280 of UE 120, and / or Figure 2 any other components in Figure 2 can perform one or more techniques associated with multiple uplink configurations for multiple antenna panel transmissions, as described in more detail elsewhere herein. For example, controller / processor 240 of base station 110, controller / processor 280 of UE 120, and / or Figure 2 any other components in Figure 7 can perform or direct the operation of, for example, process 700 of Figure 8 , process 800 of Figure 8 , and / or other processes as described herein. Memories 242 and 282 can store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 can include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE120 (e.g., directly, or after compilation, conversion, interpretation, etc.), the one or more instructions can perform or direct the operation of, for example, process 700 of Figure 7 , process 800 of Figure 8 , and / or other processes as described herein. In some aspects, executing the instructions can include running the instructions, converting the instructions, compiling the instructions, interpreting the instructions, etc. Scheduler 246 can schedule UEs for data transmission on the downlink and / or uplink.

[0044] In some aspects, the UE 120 may include: a unit for receiving a first PUSCH configuration and a second PUSCH configuration; a unit for transmitting a first uplink communication and a second uplink communication using different antenna panels at least partially based on the first PUSCH configuration and the second PUSCH configuration; and so on. In some aspects, such units may include one or more components of the UE 120 described in conjunction with Figure 2 such as the controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0045] In some aspects, the base station 110 (e.g., TRP) may include: a unit for determining a first PUSCH configuration and a second PUSCH configuration for a UE (e.g., UE 120); a unit for transmitting the first PUSCH configuration and the second PUSCH configuration to the UE so that the UE can transmit a first uplink communication and a second uplink communication using different antenna panels at least partially based on the first PUSCH configuration and the second PUSCH configuration; and so on. In some aspects, such units may include one or more components of the base station 110 described in conjunction with Figure 2 such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0046] As noted above, Figure 2 is provided as an example. Other examples may be different from the examples described with respect to Figure 2 described.

[0047] Figure 3 shows an example logical architecture of a distributed RAN 300 in accordance with aspects of the present disclosure.

[0048] The 5G access node 305 may include an access node controller 310. The access node controller 310 may be a central unit (CU) of the distributed RAN 300. In some aspects, the backhaul interface to the 5G core network 315 may terminate at the access node controller 315. The 5G core network 315 may include 5G control plane components 320 and 5G user plane components 325 (e.g., 5G gateways), and the backhaul interface for one or both of the 5G control plane and the 5G user plane may terminate at the access node controller 310. Additionally or alternatively, the backhaul interface to one or more neighbor access nodes 330 (e.g., another 5G access node 305, an LTE access node, etc.) may terminate at the access point controller 310.

[0049] The access node controller 310 may include one or more TRPs 335 and / or may communicate with one or more TRPs 335 (e.g., via the F1 control (F1-C) interface and / or the F1 user (F1-U) interface). The TRP 335 may be a distributed unit (DU) of the distributed RAN 300. In some aspects, the TRP 335 may correspond to the base station 110 described above in connection with Figure 1 description. For example, different TRPs 335 may be included in different base stations 110. Additionally or alternatively, multiple TRPs 335 may be included in a single base station 110. In some aspects, the base station 110 may include a CU (e.g., the access node controller 310) and / or one or more DUs (e.g., one or more TRPs 335). In some cases, the TRP 335 may be referred to as a cell, panel, antenna array, array, etc.

[0050] The TRP 335 may be connected to a single access node controller 310 or multiple access node controllers 320. In some aspects, there may be a dynamic configuration of split logical functions within the architecture of the distributed RAN 300. For example, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, the media access control (MAC) layer, etc. may be configured to terminate at the access node controller 310 or at the TRP 335.

[0051] In some aspects, multiple TRPs 335 may communicate (e.g., the same communication or different communications) using different quasi - co - location (QCL) relationships (e.g., different spatial parameters, different transmission configuration indicator (TCI) states, different precoding parameters, different beamforming parameters, etc.) in the same transmission time interval (TTI) (e.g., time slot, mini - slot, sub - frame, symbol, etc.) or different TTIs. In some aspects, the TCI state may be used to indicate one or more QCL relationships. The TRP 335 may be configured to provide services to the UE 120 either individually (e.g., using dynamic selection) or jointly (e.g., using coordinated transmission with one or more other TRPs 335).

[0052] As noted above, Figure 3 is provided as an example. Other examples may be different from those described with respect to Figure 3 the example.

[0053] Figure 4 is a schematic diagram of an example 400 showing multi - TRP communication (sometimes referred to as multi - panel communication) in accordance with various aspects of the present disclosure. As Figure 4 shown, multiple TRPs 405 may communicate with the same UE 410. The TRP 405 may correspond to the TRP 335 described above in connection with Figure 3 the description.

[0054] Multiple TRPs 405 (shown as TRP A and TRP B) may communicate with the same UE 410 in a coordinated manner (e.g., using coordinated multi - point transmission, etc.) to improve reliability, increase throughput, etc. The TRP 405 may coordinate such communication via an interface between the TRPs 405 (e.g., a backhaul interface, access node controller 310, etc.). When the TRPs 405 are co - located at the same base station 110 (e.g., when the TRPs 405 are different antenna arrays or panels of the same base station), the interface may have a smaller latency and / or higher capacity, and when the TRPs 405 are located at different base stations 110, the interface may have a larger latency and / or lower capacity (compared to co - location). Different TRPs 405 may communicate with the UE 410 using different QCL relationships (e.g., different TCI states), different demodulation reference signal (DMRS) ports, different layers (e.g., for multi - layer communication), etc.

[0055] As noted above, Figure 4 is provided as an example. Other examples may be different from those described with respect to Figure 4 the example.

[0056] Figure 5is a schematic diagram showing an example 500 of multi-panel uplink transmission according to various aspects of the present disclosure. As Figure 5 shown, the UE 120 may communicate with a first TRP (TRP A) 505 and a second TRP (TRP B) 505. The UE 120 may correspond to the UE 410 described above in connection with Figure 4 description. The TRP 505 may correspond to the TRP 405 described above in connection with Figure 4 description.

[0057] The first TRP 505 and the second TRP 505 may be co-located at the same base station 110 or may not be co-located. In some aspects, the first TRP 505 and the second TRP 505 are associated with the same serving cell (e.g., the same serving cell identifier). As shown, the first TRP 505 may provide downlink (DL) and uplink (UL) coverage, and the second TRP 505 may provide only UL coverage (e.g., for power saving). However, in some aspects, one or both of the first TRP 505 or the second TRP 505 may provide DL and UL coverage or only UL coverage.

[0058] As Figure 5 shown, the UE 120 may send a first PUSCH communication (PUSCH 1) to the first TRP 505 and a second PUSCH communication (PUSCH 2) to the second TRP 505. The first PUSCH communication and the second PUSCH communication may be the same communication or different communications. In some aspects, the UE 120 may send the first PUSCH communication and the second PUSCH communication concurrently (e.g., using spatial division multiplexing or frequency division multiplexing) or non-concurrently (e.g., using time division multiplexing). In some other aspects, the UE 120 may send only the first PUSCH communication or only the second PUSCH communication.

[0059] The first PUSCH communication may be scheduled by a first downlink control information (DCI) received by the UE 120 in a first control resource set (CORESET 1), and the second PUSCH communication may be scheduled by a second DCI received by the UE 120 in a second CORESET (CORESET 2). In some aspects, the first TRP 505 and the second TRP 505 may send the first DCI and the second DCI, respectively. In some aspects, one of the first TRP 505 or the second TRP 505 may send both the first DCI and the second DCI.

[0060] In a current wireless network, a UE may be configured with a single PUSCH configuration for uplink communication (e.g., for multi-panel uplink transmission). However, a single PUSCH configuration is not optimized for multi-panel uplink transmission to multiple TRPs. For example, a single PUSCH configuration may not be optimized when the UE is communicating with a first TRP that is relatively close to the UE and a second TRP that is far from the UE. As another example, a single PUSCH configuration may not be optimized when the UE is communicating with a first TRP that provides DL and UL coverage and a second TRP that provides only UL coverage. Thus, when using a single PUSCH configuration for multi-panel uplink transmission, the UE may use more processing resources or battery resources and may communicate with less throughput, etc. Some of the techniques and apparatuses described herein enable a UE to be configured with multiple PUSCH configurations for use in multi-panel uplink transmission.

[0061] As noted above, Figure 5 is provided as an example. Other examples may be different from the example regarding Figure 5 described.

[0062] Figure 6A and 6B are schematic diagrams of an example 600 of multiple uplink configurations for multi-antenna panel transmission in accordance with various aspects of the present disclosure. As Figure 6A shown, a base station 110 and a UE 120 may communicate with each other. In some aspects, the base station 110 may include the first TRP 505 and the second TRP 505 described above in connection with Figure 5 In some aspects, the base station 110 may correspond to the TRP 505 described above in connection with Figure 5 described (e.g., the first TRP 505 or the second TRP 505). In some aspects, the first TRP 505 may be associated with a first base station 110, and the second TRP 505 may be associated with a second base station 110.

[0063] As in Figure 6A and shown by reference numeral 605, the base station 110 may determine multiple PUSCH configurations (e.g., uplink configurations) for the UE 120. For example, the base station 110 may determine a first PUSCH configuration and a second PUSCH configuration for the UE 120. The multiple PUCCH configurations may be in a bandwidth part for the same serving cell. For example, the first TRP505 and the second TRP 505 may be associated with the same serving cell (e.g., the same serving cell identifier).

[0064] As shown by reference numeral 610, the base station 110 may send (e.g., via Radio Resource Control (RRC) signaling) and the UE 120 may receive multiple PUSCH configurations. For example, the first TRP 505 may send a first PUSCH configuration, and the second TRP 505 may send a second PUSCH configuration. As another example, the TRP 505 may send both the first PUSCH configuration and the second PUSCH configuration.

[0065] In some aspects, the first PUSCH configuration and the second PUSCH configuration may be different. For example, one or more parameters indicated by the first PUSCH configuration may be different from one or more parameters indicated by the second PUSCH configuration.

[0066] As Figure 6A shown, in some aspects, the first PUSCH configuration may be associated with a first panel identifier, and the second PUSCH configuration may be associated with a second panel identifier. In some aspects, the panel identifier may be a CORESET pool index value. In other words, the first PUSCH configuration may indicate a first CORESET pool index value (e.g., associated with a first COREST), and the second PUSCH may indicate a second CORESET pool index value (e.g., associated with a second CORESET). The first CORESET pool index value may be one of 0 or 1, and the second CORESET pool index value may be the other of 0 or 1. In some aspects, additionally or alternatively, the panel identifier may be a sounding reference signal (SRS) resource indicator, an SRS resource set indicator, an uplink spatial relation information indicator, or an uplink TCI state indicator.

[0067] In some aspects, the first PUSCH configuration may indicate a first data scrambling identity (e.g., dataScramblingIdentityPUSCH), and the second PUSCH configuration may indicate a second data scrambling identity (e.g., different from the first data scrambling identity). In this way, the randomization of interference between multiple PUSCH transmissions may be improved. In some aspects, the first PUSCH configuration may indicate a first power control configuration (e.g., pusch-PowerControl), and the second PUSCH configuration may indicate a second power control configuration (e.g., different from the first power control configuration). For example, one or more parameters indicated by the first power control configuration (e.g., p0 value, closed-loop index, path loss reference signal identifier, etc.) may be different from one or more parameters indicated by the second power control configuration. In this way, the power control parameters may be optimized for each target TRP 505.

[0068] In some aspects, the first PUSCH configuration may indicate a first MCS table, and the second PUSCH configuration may indicate a second MCS table (e.g., different from the first MCS table). For example, the first MCS table and the second MCS table may be associated with different modulation types, different transform precodings, etc. As another example, one or more MCSs mapped by the first MCS table may be different from one or more MCSs mapped by the second MCS table. That is, one or more MCSs mapped by the first MCS table and one or more MCSs mapped by the second MCS table may include different modulation orders, different target code rates, different spectral efficiencies, and / or different combinations of modulation order, target code rate, and spectral efficiency.

[0069] In some aspects, the first PUSCH configuration may indicate a first transform precoder indication (e.g., transformPrecoder indication), and the second PUSCH configuration may indicate a second transform precoder indication (e.g., different from the first transform precoder indication). For example, the first transform precoder indication may be one of enabled or disabled, and the second transform precoder indication may be the other of enabled or disabled. As an example, the first PUSCH configuration (e.g., for transmission to the first TRP 505) may enable the transform precoder, and the second PUSCH configuration (e.g., for transmission to the second TRP 505) may disable the transform precoder. When the transform precoder is enabled for PUSCH transmission, DFT-s-OFDM may be used for PUSCH transmission, and when the transform precoder is disabled for PUSCH transmission, CP-OFDM may be used for PUSCH transmission.

[0070] In some aspects, the first PUSCH configuration may indicate a first codebook subset type (e.g., codebookSubset), and the second PUSCH configuration may indicate a second codebook subset type (e.g., different from the first codebook subset type). The first codebook subset type or the second codebook subset type may be one of the following: non-coherent; partially coherent and non-coherent; or fully coherent, partially coherent, and non-coherent. In some aspects, the first PUSCH configuration may indicate a first maximum rank (e.g., maxRank), and the second PUSCH configuration may indicate a second maximum rank (e.g., different from the first maximum rank). The maximum rank may indicate the maximum number of transport layers to be used. For example, the first maximum rank or the second maximum rank may have a value of 1, 2, 3, or 4. As an example, the first PUSCH configuration (e.g., for transmission to the first TRP 505) may indicate a maximum rank of 1, and the second PUSCH configuration (e.g., for transmission to the second TRP 505) may indicate a maximum rank of 4. In some aspects, the first PUSCH configuration may indicate a first uplink transmission scheme, and the second PUSCH configuration may indicate a second uplink transmission scheme (e.g., different from the first uplink transmission scheme). The uplink transmission scheme may be one of codebook-based MIMO transmission or non-codebook-based MIMO transmission.

[0071] In some aspects, the first PUSCH configuration may indicate a first pi / 2 binary phase shift keying (BPSK) indication (e.g., tp-pi2BPSK), and the second PUSCH configuration may indicate a second pi / 2 BPSK indication (e.g., different from the first pi / 2 BPSK indication). For example, the first pi / 2 BPSK indication may be one of enabled or disabled, and the second pi / 2 BPSK indication may be the other of enabled or disabled. In some aspects, the target code rate for MCS may depend on the pi / 2 BPSK indication (e.g., transmit precoder pi / 2 BPSK indication). For example, if pi / 2 BPSK is enabled, a first value may be used to calculate the target code rate, and if pi / 2 BPSK is disabled, a second value may be used to calculate the target code rate.

[0072] As in Figure 6BAs shown in and by reference numeral 615, the base station 110 may transmit and the UE 120 may receive multiple DCIs that schedule multiple uplink communications (e.g., multi-panel uplink transmissions) of the UE 120. For example, the base station 110 may transmit a first DCI (DCI 1) that schedules a first uplink communication (PUSCH 1) and a second DCI (DCI 2) that schedules a second uplink communication (PUSCH 2) to the UE 120. In some aspects, the first TRP 505 may transmit the first DCI, and the second TRP 505 may transmit the second DCI. In some aspects, the TRP 505 may transmit both the first DCI and the second DCI.

[0073] The UE 120 may receive the first DCI for the first uplink communication in a first CORESET (CORESET 1) and the second DCI for the second uplink communication in a second CORESET (CORESET 2). The first CORESET may be associated with a first CORESET pool index value (e.g., 0), and the second CORESET may be associated with a second CORESET pool index value (e.g., 1).

[0074] Accordingly, the UE 120 may determine the PUSCH configuration (e.g., a first PUSCH configuration or a second PUSCH configuration) to be used for an uplink communication (e.g., the first uplink communication or the second uplink communication) at least in part based on whether the PUSCH configuration indicates the same CORESET pool index value as the CORESET in which the DCI for the uplink communication is received. For example, if the DCI that schedules the uplink communication is received in a CORESET associated with a CORESET pool index value of 1, the UE 120 may determine that the uplink communication will use the PUSCH configuration that indicates the CORESET pool index value of 1.

[0075] As shown by reference numeral 620, the UE 120 may transmit multiple uplink communications using different antenna panels. For example, the UE 120 may use a first antenna panel to transmit a first uplink communication to the first TRP 505 and a second antenna panel to transmit a second uplink communication to the second TRP 505. The antenna panel may include an antenna port group and may be identified by an explicit panel identifier or an implicit resource identifier (such as a reference signal identifier, a TCI identifier, etc.). The UE 120 may transmit the first uplink communication and the second uplink communication concurrently (e.g., using spatial division multiplexing or frequency division multiplexing) or non-concurrently (e.g., using time division multiplexing).

[0076] In some aspects, the UE 120 may transmit the first uplink communication according to the first PUSCH configuration (or the second PUSCH configuration) based at least in part on a determination that the first uplink communication is scheduled by DCI received in a CORESET associated with the same CORESET pool index value indicated by the first PUSCH configuration (or the second PUSCH configuration). Similarly, the UE 120 may transmit the second uplink communication according to the second PUSCH configuration (or the first PUSCH configuration) based at least in part on a determination that the second uplink communication is scheduled by DCI received in a CORESET associated with the same CORESET pool index value indicated by the second PUSCH configuration (or the first PUSCH configuration).

[0077] As noted above, Figure 6A and 6B are provided as one or more examples. Other examples may be different from those Figure 6A and 6B described with respect to

[0078] Figure 7 is a schematic diagram illustrating an example process 700, such as may be performed by a UE, in accordance with various aspects of the present disclosure. Example process 700 is an example in which a UE (e.g., UE 120, etc.) performs operations associated with multiple uplink configurations for multiple antenna panel transmissions.

[0079] As Figure 7 shown, in some aspects, process 700 may include: receiving a first PUSCH configuration and a second PUSCH configuration (block 710).

For example, a base station (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.) may send a first PUSCH configuration and a second PUSCH configuration to the UE, such that the UE can use different antenna panels to send a first uplink communication and a second uplink communication at least partially based on the first PUSCH configuration and the second PUSCH configuration, as described above.
