[0019] Turning to Figure 1, which shows a block diagram of one possible and non-limiting example in which the examples can be practiced, a user equipment (UE) 110, a radio access network (RAN) node 170, and (multiple) network elements 190 are shown. Figure 1 In the example, User Equipment (UE) 110 wirelessly communicates with Wireless Network 100. The UE is a wireless device that can access Wireless Network 100. UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130 interconnected via one or more buses 127. Each of the one or more transceivers 130 includes a receiver Rx 132 and a transmitter Tx 133. The one or more buses 127 may be address, data, or control buses and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, fiber optic cables, or other optical communication devices. The one or more transceivers 130 are connected to one or more antennas 128. The one or more memories 125 include computer program code 123. UE 110 includes a module 140, which includes one or both of portions 140-1 and / or 140-2, which may be implemented in various ways. Module 140 may be implemented in hardware as module 140-1, such as as part of one or more processors 120. Module 140-1 can also be implemented as an integrated circuit or via other hardware, such as a programmable gate array. In another example, module 140 can be implemented as module 140-2, which is implemented as computer program code 123 and executed by one or more processors 120. For example, one or more memories 125 and computer program code 123 can be configured to perform one or more of the operations described herein with the user device 110 using one or more processors 120. UE 110 communicates with RAN node 170 via wireless link 111.

[0020] In this example, RAN node 170 is a base station that provides access to wireless network 100 for wireless devices such as UE 110. RAN node 170 can be, for example, a base station for 5G (also known as New Radio (NR)). In 5G, RAN node 170 can be an NG-RAN node, which is defined as a gNB or ng-eNB. A gNB is a node that provides NR user plane and control plane protocol termination to the UE and is connected to 5GC (such as, for example, network elements 190) via an NG interface (such as connection 131). An ng-eNB is a node that provides E-UTRA user plane and control plane protocol termination to the UE and is connected to 5GC via an NG interface (such as connection 131). NG-RAN nodes can include multiple gNBs, which can also include a central unit (CU) (gNB-CU) 196 and multiple distributed units (DUs) (gNB-DU), where DU 195 is shown. Note that DU 195 can include or be coupled to and control a radio unit (RU). gNB-CU 196 is a logical node that carries the Radio Resource Control (RRC), SDAP, and PDCP protocols of the gNB or the RRC and PDCP protocols of the en-gNB, controlling the operation of one or more gNB-DUs. gNB-CU 196 terminates the F1 interface connected to gNB-DU 195. The F1 interface is shown as reference numeral 198, although reference numeral 198 also shows links between remote elements and centralized elements of RAN node 170, such as the link between gNB-CU 196 and gNB-DU 195. gNB-DU 195 is a logical node that hosts the RLC, MAC, and PHY layers of the gNB or en-gNB, and its operation is partially controlled by gNB-CU 196. One gNB-CU 196 supports one or more cells. A cell can be supported by one gNB-DU 195, or a cell can be supported / shared by multiple DUs under a shared RAN. The gNB-DU 195 terminates the F1 interface 198 connected to the gNB-CU 196. Note that the DU 195 is considered to include the transceiver 160, for example, as part of the RU; however, some examples in this regard may show the transceiver 160 as part of a separate RU, for example, under the control of and connected to the DU 195. The RAN node 170 can also be an eNB (evolved NodeB) base station for LTE (Long Term Evolution), or any other suitable base station or node.

[0021] RAN node 170 includes one or more processors 152, one or more memories 155, one or more network interfaces (N / WI / F) 161, and one or more transceivers 160 interconnected via one or more buses 157. Each of the one or more transceivers 160 includes a receiver Rx 162 and a transmitter Tx 163. The one or more transceivers 160 are connected to one or more antennas 158. The one or more memories 155 include computer program code 153. CU 196 may include processor(s) 152, one or more memories 155, and network interfaces 161. Note that DU 195 may also include its own memories and processor(s), and / or other hardware, but these are not shown.

[0022] RAN node 170 includes module 150, which includes one or both of portions 150-1 and / or 150-2. Module 150 can be implemented in various ways. Module 150 can be implemented in hardware as module 150-1, such as as part of one or more processors 152. Module 150-1 can also be implemented as an integrated circuit or via other hardware, such as a programmable gate array. In another example, module 150 can be implemented as module 150-2, which is implemented as computer program code 153 and executed by one or more processors 152. For example, one or more memories 155 and computer program code 153 are configured, together with one or more processors 152, to enable RAN node 170 to perform one or more operations described herein. Note that the functionality of module 150 can be distributed, such as being distributed between DU 195 and CU 196, or implemented only in DU 195.

[0023] One or more network interfaces 161 communicate over a network (such as via links 176 and 131). Two or more gNBs 170 may communicate using, for example, link 176. Link 176 may be wired, wireless, or both, and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or other suitable interfaces for other standards.

[0024] One or more buses 157 may be address, data, or control buses and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, optical fiber or other optical communication equipment, wireless channels, etc. For example, one or more transceivers 160 may be implemented as a Remote Radio Header (RRH) 195 for LTE or a Distributed Unit (DU) 195 for a gNB implementation of 5G, wherein other elements of the RAN node 170 may be physically located in a different location from the RRH / DU 195, and one or more buses 157 may be partially implemented as, for example, fiber optic cables or other suitable network connections to connect other elements of the RAN node 170 (e.g., Central Unit (CU), gNB-CU 196) to the RRH / DU 195. Reference numeral 198 also indicates those suitable network links(s).

[0025] A RAN node / gNB may include one or more TRPs, and the methods described herein can be applied to these TRPs. Figure 1 The diagram shows that RAN node 170 includes TRP 51 and TRP 52 in addition to the TRP represented by transceiver 160. Similar to transceiver 160, TRP 51 and TRP 52 may each include a transmitter and a receiver. RAN node 170 may carry or include... Figure 1 Other TRPs not shown in the diagram.

[0026] In NR, relay nodes are called Integrated Access and Backhaul nodes. The mobile termination portion of an IAB node facilitates backhaul (parent link) connections. In other words, the mobile termination portion includes functions carrying UE capabilities. The distributed unit portion of an IAB node facilitates so-called access link (sub-link) connections (i.e., for access link UEs, and for backhaul to other IAB nodes in the case of multi-hop IABs). In other words, the distributed unit portion is responsible for certain base station functions. IAB scenarios may follow a so-called decoupled architecture, where the central unit hosts higher-layer protocols for the UE and terminates at the control plane and user plane interfaces of the 5G core network.

[0027] It is important to note that the description in this article refers to a "cell" performing functions, but it should be clear that the equipment forming the cell can perform these functions. A cell constitutes part of a base station. That is, each base station can have multiple cells. For example, for a single carrier frequency and associated bandwidth, there can be three cells, each covering one-third of a 360-degree area, making the coverage area of ​​a single base station approximately elliptical or circular. Furthermore, each cell can correspond to a single carrier, and a base station can use multiple carriers. Therefore, if each carrier has three 120-degree cells and two carriers, the base station has a total of six cells.

[0028] Wireless network 100 may include network element 190, which may include core network functions and provides connectivity to other networks (such as telephone networks and / or data communication networks (e.g., the Internet)) via one or more links 181. Such core network functions for 5G may include location management functions (multiple LMFs) and / or access and mobility management functions (multiple AMFs) and / or user plane functions (multiple UPFs) and / or session management functions (multiple SMFs). Such core network functions for LTE may include MME (Mobility Management Entity) / SGW (Serving Gateway) functions. Such core network functions may include SON (Self-Organizing / Optimizing Network) functions. These are merely example functions that may be supported by network element 190; note that both 5G and LTE functions may be supported. RAN node 170 is coupled to network element 190 via link 131. Link 131 may be implemented as, for example, an NG interface for 5G, or an S1 interface for LTE, or other suitable interfaces for other standards. Network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (multiple N / WI / F) 180 interconnected via one or more buses 185. The one or more memories 171 include computer program code 173. The computer program code 173 may include SON and / or MRO functions 172.

[0029] Wireless network 100 can implement network virtualization, which is the process of combining hardware and software network resources and network functions into a single software-based management entity or virtual network. Network virtualization involves platform virtualization, often combined with resource virtualization. Network virtualization is classified into external virtualization and internal virtualization. External virtualization combines many networks or parts of networks into virtual units, while internal virtualization provides network-like functionality to software containers on a single system. Note that the virtualized entities created by network virtualization are still implemented to some extent using hardware (such as processors 152 or 175 and memory 155 and 171), and these virtualized entities also produce technical effects.

[0030] Computer-readable storage devices 125, 155, and 171 can be of any type suitable for the local technical environment and can be implemented using any suitable data storage technology, such as semiconductor-based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, non-transitory memory, transient memory, fixed memory, and removable memory. Computer-readable storage devices 125, 155, and 171 can be components for performing storage functions. Processors 120, 152, and 175 can be of any type suitable for the local technical environment and, as non-limiting examples, can include one or more of the following: general-purpose computers, special-purpose computers, microprocessors, digital signal processors (DSPs), and processors based on multi-core processor architectures. Processors 120, 152, and 175 can be components for performing functions such as controlling UE 110, RAN node 170, network element(s) 190, and other functions described herein.

[0031] Generally, various example embodiments of user equipment 110 may include, but are not limited to, cellular phones, such as smartphones, tablets, personal digital assistants (PDAs) with wireless communication capabilities, portable computers with wireless communication capabilities, image capture devices (such as digital cameras with wireless communication capabilities), gaming devices with wireless communication capabilities, music storage and playback devices with wireless communication capabilities, internet devices (including those that allow wireless internet access and browsing), tablets with wireless communication capabilities, head-mounted displays (such as those implementing virtual / augmented / mixed reality), and portable units or terminals combining these functions. UE 110 may also be a vehicle (such as a car) or a UE installed in a vehicle, a UAV (such as a drone) or a UE installed in a UAV. User equipment 110 may be a terminal device, such as a mobile phone, mobile device, sensor device, etc., which may be a device used by a user or not.

[0032] UE 110, RAN node 170, and / or (multiple) network elements 190 (as well as associated memory, computer program code, and modules) can be configured to (e.g., partially) implement the methods described herein. Therefore, computer program code 123, module 140-1, module 140-2, and...

Figure 1The other elements / features shown can be configured to implement the network element-related aspects of the examples described herein.

[0033] This introduces a suitable, but non-limiting, technical context for practicing the exemplary embodiments, which are now described in more detail.

[0034] The examples described in this paper relate to the development of the 3GPP New Radio (NR) physical layer in Rel-19 and later versions (e.g., 6G). More specifically, this paper describes a novel precoder indication method and the corresponding UE transmission procedure for simultaneous multi-panel PUCCH transmission with one or more Transmit Receive Points (TRPs), where the TRPs can be deployed in a single (S)-DCI and multiple (m)-DCI configurations.

[0035] Figure 2 An example TCI framework is depicted, providing the QCL relationship between source (202, 208) and target (206, 212) signals. In this example TCI framework, a single TCI state can be indicated to the UE, and this TCI state, or the RS(s) indicated by the TCI state, is used for transmission and reception assumptions of PDCCH / PDSCH / CSI-RS and / or PUCCH / PUSCH / SRS. The principle of providing information to the UE to estimate parameters (204, 210) related to the reception or transmission of downlink or uplink signals / channels is correspondingly described in... Figure 2 It is displayed in the middle.

[0036] In this example TCI framework, the beam indication or TCI state indication (i.e., indicating which TCI state is used for transmission and / or reception assumptions for the signal and channel associated with the TCI state) has the following steps (1-3):

[0037] 1. For the serving cell, the TCI state type is configured as either Joint UL / DL or Separate UL / DL. In Joint UL / DL, the indicated TCI state is used for both uplink and downlink, while in Separate DL and UL, it is indicated separately (a TCI code point indicated in the DCI may include only DL TCI, only UL TCI, or both DL and UL TCI states). If the TCI state type is Joint, the UE is configured with a single TCI state list using RRC.

[0038] 2. If the TCI status types are separate, the UE is configured with both a DL TCI status list and a UL TCI status list. Configuration is accomplished using RRC signaling, while the MAC CE selects and activates up to eight (in Rel-17) TCI code points, one of which can be indicated via DCI. As previously mentioned, a TCI code point may include only DL TCI status, only UL TCI status, or both DL and UL TCI statuses.

[0039] 3. To indicate the TCI state (joint) or separate TCI states (UL and DL), the network provides the TCI code point (value in the DCI message) corresponding to the TCI code point in the MAC CE that is active (multiple) TCI code points. Upon receiving the DCI-based beam indication (DCI code point), the UE applies the indicated TCI state to the indicated channel (PDSCH / PDCCH / PUSCH / PUCCH).

[0040] Compared to a single (S)-DCI scheme, a multi-(M)-DCI-based uplink multi-panel PUSCH scheme with SDM and SFN can be used to improve throughput and reliability and reduce latency.

[0041] In the SDM-based scheme, different layer / DMRS ports of a PUSCH are precoded separately and transmitted simultaneously from different UE panels.

[0042] In an SFN-based transmission scheme, all identical layer / DMRS ports during a PUSCH transmission are simultaneously transmitted using two different precoders from two different UE panels associated with different TCI states.

[0043] In both SDM and SFN with codebook-based precoding, the UE is provided with separate precoder matrices for each transmit panel in DCI via two TPMI entries.

[0044] Figure 3An example of simultaneous multi-panel PUCCH transmission with two TRPs (TRP 302 and TRP 304) and two antenna panels (308, 310) is shown. As illustrated, the downlink DCI (e.g., format 1_1 / 1_2) indicates the TCI code point, which includes two TCI states (joint UL and DL or separate UL) associated with the two different TRPs. UE 110 can apply the indicated TCI states (associated with the code point values) to a single PUCCH resource with single-layer multi-panel transmission toward the two different TRPs (303, 304). In principle, the UE can determine non-codebook-based precoding based on the indicated TCI states, where the downlink NZP-CSI-RS / SSB resources are used as the spatial QCL-“typeD” source for the PUCCH resource. Therefore, the network lacks the possibility of "controlling" the type of precoding applied (i.e., codebook / non-codebook) and the precoding vector associated with the antenna panel used for PUCCH transmission, which can lead to potential degradation in PUCCH demodulation performance, such as in terms of coverage.

[0045] Since there is currently no mechanism for the network to specifically control the applied precoding antenna panel, or even to "force" the use of precoding (e.g., using precoder 312 or precoder 314) for simultaneous PUCCH transmission, demodulation and channel estimation performance may degrade compared to the case where the UE is "forced" to apply PUCCH precoding. Furthermore, particularly in scenarios with limited coverage, it may be beneficial for the network to control panel-specific precoders (e.g., precoder 312 or precoder 314) for simultaneous PUCCH transmission to achieve enhanced channel estimation and demodulation performance for PUCCH. Therefore, the examples described herein address the aforementioned issues and provide corresponding solutions.

[0046] This paper describes a novel precoder indication method for simultaneous multi-panel PUCCH transmission and the corresponding UE transmission process.

[0047] In the example implementation, the UE reports new capability information related to supporting simultaneous multi-panel PUCCH transmission based on codebook and / or non-codebook.

[0048] In the example embodiment, the UE is configured at a higher layer to apply the same uplink precoding to an STxMP PUCCH with rank constraints (e.g., rank 1).

[0049] In one option, a new Boolean information unit (e.g., follow-PUSCH-STxMP (or alternative locations,) follow-PUSCH-STxMP-Prec It is configured in various parameters, such as high-level parameters. PUCCH-Resource set or PUCCH-Resource (i-iii): i) when PUCCH-ResourceIn the set follow-PUSCH-STxMP-Prec and PUCCH-Config In multipanelSfnScheme When configured, the UE should apply the same precoder associated with the first SRI and the second SRI (non-codebook) or the first TPMI and the second TPMI (codebook). In one example embodiment, the precoder applies a rank constraint, for example, a rank 1 constraint (i.e., the first layer of the first SRI and the first layer of the second SRI (non-codebook), and the first layer of the first TPMI and the first layer of the second TPMI (codebook), as in the most recent STxMP PUSCH transmission triggered by, for example, DCI 0_1 / 0_2 or a configured license type 1 or type 2 w / DCI activation, regardless of the uplink STxMP scheme used for PUSCH; ii) when follow-PUSCH-STxMP-Prec When configured in the PUCCH-Resource set, all PUCCH resources in the PUCCH-Resource set are assumed to follow STxMP PUSCH precoding (as defined above); iii) when follow-PUSCH-STxMP-Prec exist PUCCH-Resource When configured, PUCCH-Resource Each PUCCH resource in the centralization should independently follow STxMP PUSCH precoding (as defined above).

[0050] In another option, high-level parameters PUCCH-Resource Collection or PUCCH-Resource Configured with new Boolean information units follow-PUSCH-STxMP-Prec and new information units PUCCH-Prec-Type , is configured as " nonCodeBook "or" codebook ".when follow-PUSCH-STxMP and PUCCH-Prec-Type =" nonCodebook "When configured, the UE should apply the same precoder associated with the first SRI and the second SRI (non-codebook), as in the most recent STxMP PUSCH transmission triggered by DCI 0_1 / 0_2 or configured license type 1 or type 2 with DCI activation. When follow-PUSCH-STxMP and PUCCH-Prec-Type =" Codebook When configured, the UE should apply the same precoder associated with the first TPMI and the second TPMI (codebook), as in the most recent STxMP PUSCH transmission triggered by, for example, DCI 0_1 / 0_2 or a configured license type 1 or type 2 w / DCI activation. In the example embodiment, the precoder applies a rank constraint, such as a rank 1 constraint.

[0051] In example embodiments, lower-layer parameters can be used, such as, for example, MAC-CE or DCI. For instance, when UE 110 receives DCI 1_1 / 1_2 with an indicated UL TCI state and DCI 0_1 / 0_2 with a first SRI, a second SRI, and / or a first TPMI and a second TPMI within N consecutive time slots, where N is configured by the network, the UE is implicitly instructed to apply the same precoding to the STxMP PUCCH resource transmission as the most recent SDM / SFN-based STxMP PUSCH (described in previous embodiments).

[0052] In another example, when the UE receives DCI 1_1 / 1_2 with an indicated UL TCI status and a value " TRUE "New code point" follow-PUSCH-STxMP At this time, the UE is explicitly instructed to apply the same precoding to STxMP PUCCH resource transmission as the most recent SDM / SFN-based STxMP PUSCH (described in previous embodiments).

[0053] In one implementation, examples of possible implementations of the TS 38.331 specification are defined, along with proposed modifications (in / / inner mark) in having PUCCH It is defined in PUCCH-ResourceSet of -config. (IE) PUCCH-Config Used to configure UE-specific PUCCH parameters applicable to a specific BWP.

[0055] In another alternative implementation example of the possible implementation of the TS 38.331 specification, the proposed modification (in / / inner mark) in having PUCCH -config PUCCH - Defined in Resource.

[0057] In one example embodiment, transmissions using one or more physical uplink control channels of one or more precoders associated with an SDM / SFN-based STxMP PUSCH are configuration-based, with or without repetition. In one example embodiment, the UE receives the configuration from the network.

[0058] It is worth noting that PUCCH resources can have the same or different periods, and various PUCCH formats can be defined according to physical resource allocation, number of bits, etc.

[0059] Figure 4 This illustrates an example of multi-panel PUCCH transmission configured with follow-PUSCH in the PUCCH-ResourceSet. When PUCCH-Resource centralized follow-PUSCH-STxMP-Prec and PUCCH-Config In multipanelSfnScheme When configured, the UE should apply the same precoder associated with the first TPMI and the second TPMI (codebook) having rank 1 constraints (the first layer of the first TPMI and the first layer of the second TPMI codebook), as in the most recent STxMP PUSCH transmission triggered by DCI0_1 / 0_2.

[0060] like Figure 4 As shown, the combined UL and DL states are indicated at 402 via downlink control information (S-DCI 1_1 / 1_2), with states TCI state #1 and TCI state #2. Item 404 shows the old indicated states, including TCI state #4 and TCI state #6. HARQ-ACK is indicated at 406, and UL SRS sets #1 and #2 are displayed at 410. Item 408 shows the transition to the newly indicated UL TCI states, i.e., TCI state #1 and TCI state #2. At 412, downlink control information is received (e.g., S-DCI 0_1 / 0_2). Item 414 shows the application of the newly indicated TCI states, i.e., TCI state #1 and TCI state #2. At 416, the UE applies the same precoding to the STxMP PUCCH as to the STxMP PUSCH with rank 1 restriction. Figure 4 The illustrations show a UL SRS resource set (418) using a codebook, a PDCCH (420) with DL or UL DCI, an STxMP PUSCH (422) with codebook-based precoding and multiple TX antenna panels, an STxMP PUCCH (424) with codebook-based precoding and multiple TX antenna panels, and an STxMP DMRS (426) with codebook-based precoding and multiple TX antenna panels.

[0061] In one implementation, upon receiving an SRI for simultaneous PUSCH transmission based on SDM or SFN, the UE stores the first column (layer 1) of the corresponding precoder matrix into memory. For the next PUSCH transmission, the UE retrieves the precoder from memory and applies the precoder vector to the corresponding PUSCH transmission.

[0062] When a PUSCH TXConfig configured with “nonCodebook” and a PUCCH-Config with multipanelsfnScheme “configured”, along with DCI 1_1 / 1_2, have been detected, the UE separately determines its antenna panel-specific precoder for PUCCH transmission based on a calculated channel estimate associated with downlink reference signal resources (e.g., NZP-CSI-RS or SSB) related to the indicated TCI state. Due to UE-specific implementation limitations, channel reciprocity between the downlink and uplink is not fully established. The received signal experiences equal signal strength on the different RF RX paths associated with each antenna panel. However, this is not the case when uplink transmissions occur simultaneously across different antenna panels. The reason for this is that, for example, one or more TX antenna panels with RF branches associated with antenna ports for uplink reference signals and / or uplink data (e.g., PUSCH) or control channels (e.g., PUCCH) can share a single PA. Because the physical distance between the outputs of the PA and RF TX antenna connectors differs, there may be different insertion (due solely to wiring) and / or other implementation-specific losses, resulting in power imbalances between signals transmitted via different antenna panels. To compensate for this imbalance in simultaneous uplink transmissions, the UE should apply additional antenna panel-specific TX power to compensate for the implementation-specific insertion loss associated with each antenna panel. This additional antenna panel-specific TX power "correction / compensation" cannot be obtained via standardized downlink reference signal resource measurements associated with path loss estimation used in standardized uplink TX power control methods. Furthermore, the network assumes that the power imbalance does not exist and is not known to the network by any means or signaling. Therefore, to achieve a common understanding of the nominal TX power between the UE and the network, the UE should perform TX power "compensation / equalization" for implementation-specific attenuation / insertion losses across different antenna panels. Of course, the actual applied output power of each antenna may differ from the different path loss gains associated with the target TRP / RX panels on the network side (i.e., the reference signal resources associated with the indicated TCI state). To achieve specific TX power compensation / equalization across different antenna panels used for simultaneous PUCCH transmission, the following UE steps need to be performed (steps 1-6):

[0063] Step 1: The UE understands the implementation-specific power / insertion loss between different TX antenna panels. These values ​​have been obtained, for example, during the UE / device manufacturing phase, or there are some UE implementation-specific measurements within the UE. Once these values ​​are known to the UE, they are stored in the UE's memory.

[0064] Step 2: The UE determines different combinations of TX antenna panel pairs from all TX antenna panels, selects an "anchor / master" antenna panel and a secondary antenna panel for each pair, and calculates the relative power difference between the antenna panels within the pair. For example, for an antenna panel pair, antenna panel 1 is the master panel and antenna panel 2 is the secondary panel, where panel 2 has a loss of 3 dB relative to panel 1. For each antenna panel pair, the UE also calculates the power difference relative to the optimal antenna panel among all antenna panels. Alternatively, the UE selects a master antenna panel among all antenna panels that has the minimum realization / insertion loss among all antenna panels. Then, for each antenna panel pair, the power difference between the two antenna panels within that pair relative to the master antenna panel is calculated. In both cases, these values ​​are stored in the memory of the UE for each pair.

[0065] Step 3: The UE calculates the path loss estimate for each TX antenna panel based on the DL RS resources of the path loss reference associated with each indicated TCI state, without assuming any implementation loss.

[0066] Step 4: When two distinct TCI states are indicated and the UE is configured to apply PUSCH precoding to the STxMP PUCCH, the UE applies the same TX antenna panel to a single PUCCH resource as for SDM / SFN-based STxMP PUSCH transmission. Before applying the rank-1 restricted precoder to each antenna panel for the STxMP PUSCH, the UE calculates a new path loss estimate, adding the antenna panel-specific implementation loss relative to the main antenna panel (global loss of all antenna panels or local loss within the pair) to the calculated path loss value calculated in Step 3 (e.g., new antenna panel-specific path loss value = antenna panel-specific path loss value + antenna panel-specific implementation loss [in dB]).

[0067] Typically, when two distinct TCI states are indicated and the UE is configured to apply PUSCH precoding for simultaneous transmission of PUCCH across multiple antenna arrangements, the UE will apply the same TX antenna arrangement for a single PUCCH resource as for SDM / SFN-based PUSCH transmissions across multiple antenna arrangements. Antenna arrangements (including those for simultaneous transmission of PUSCH across multiple antenna arrangements and those for simultaneous transmission of PUCCH across multiple antenna arrangements) may include one or more antenna panels, or antenna arrangements (including those for simultaneous transmission of PUSCH across multiple antenna arrangements and those for simultaneous transmission of PUCCH across multiple antenna arrangements) may include one or more transmission configuration indicator states.

[0068] Step 5: Apply the new antenna panel-specific "equalization / correction" path loss value calculated in Step 4 to the antenna panel-specific (i.e., per TCI state) UL power control equation for the PUCCH (also considering the PRB associated with the PUCCH). This step is calculated for both antenna panels associated with the antenna panel pair.

[0069] Step 6: The UE calculates the total PUCCH TX power by adding the specific power values ​​of the two antenna panels (calculated in Step 5) and checks that the total TX power of the PUCCHs on both antenna panels does not exceed the total uplink power budget for PUCCH transmission. If the calculated total power is less than the total TX power budget for PUCCH transmission, the UE should apply the calculated uplink power control value to the indicated TCI state and the single PUCCH transmission; otherwise, the UE only applies the first indicated TCI state and the corresponding calculated uplink power control value to the single antenna panel PUCCH transmission in Step 5.

[0070] In one alternative implementation, the UE scales elements of the antenna panel-specific precoder vector using antenna panel-specific implementation values ​​(i.e., scalar values) instead of equalizing / correcting uplink power control.

[0071] The examples described in this paper offer several technical advantages. The methods described here enable the network to have complete control over whether to use precoding and its precoding type (codebook / non-codebook) for STxMP deployments targeting S-DCI and M-DCI. For codebook-based PUCCH, the method can precisely determine which precoding vector to apply for PUCCH precoding. Therefore, this provides the network scheduler with greater flexibility in pairing different UEs with the same time and frequency resources. From the UE's perspective, the ideas described in this paper simplify STxMP PUCCH operation. The methods described in this paper are applicable to both S-DCI and M-DCI deployments.
