[0018] Steering Figure 1, which shows a block diagram of one possible and non-limiting example in which the example may 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 of , a user equipment (UE) 110 wirelessly communicates with a wireless network 100. A UE is a wireless device that can access the wireless network 100. The UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130 interconnected by 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 can be address, data, or control buses, and can include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, optical fiber or other optical communication devices, etc. 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. The UE 110 includes a module 140, which includes one or both of the parts 140-1 and / or 140-2, which can be implemented in a variety of ways. The module 140 can be implemented in hardware as the module 140-1, such as as part of the one or more processors 120. Module 140-1 may also be implemented as an integrated circuit or by other hardware (such as a programmable gate array). In another example, module 140 may 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 may be configured to perform one or more operations described herein with one or more processors 120 using user equipment 110. UE 110 communicates with RAN node 170 via wireless link 111.

[0019] The RAN node 170 in this example is a base station that provides access to the wireless network 100 for wireless devices such as UE 110. The RAN node 170 may be, for example, a base station for 5G, also known as New Radio (NR). In 5G, the RAN node 170 may be a 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 a 5GC such as, for example, network element (s) 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 a 5GC via an NG interface such as connection 131. The NG-RAN node may include multiple gNBs, which may also include a central unit (CU) (gNB-CU) 196 and (multiple) distributed units (DU) (gNB-DU), of which DU 195 is shown. Note that DU 195 may include or be coupled to and control a radio unit (RU). The gNB-CU 196 is a logical node that hosts the radio resource control (RRC), SDAP and PDCP protocols of the gNB or the RRC and PDCP protocols of the en-gNB, which controls the operation of one or more gNB-DUs. The gNB-CU 196 terminates the F1 interface connected to the gNB-DU 195. The F1 interface is shown as reference numeral 198, although reference numeral 198 also shows the link between the remote elements of the RAN node 170 and the centralized elements of the RAN node 170, such as the link between the gNB-CU 196 and the gNB-DU 195. The 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 the gNB-CU 196. One gNB-CU 196 supports one or more cells. One cell can be supported by one gNB-DU 195, or one cell can be supported / shared by multiple DUs under RAN sharing. 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, but some examples in this regard may include the transceiver 160 as part of a separate RU, for example under the control of the DU 195 and connected to the DU 195. The RAN node 170 may also be an eNB (evolved NodeB) base station for LTE (Long Term Evolution), or any other suitable base station or node.

[0020] The 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 by 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. The CU 196 may include (multiple) processors 152, one or more memories 155, and a network interface 161. Note that the DU 195 may also contain its own memory and (multiple) processors, and / or other hardware, but these are not shown.

[0021] The RAN node 170 includes a module 150, which includes one or both of the parts 150-1 and / or 150-2, and the module 150 can be implemented in a variety of ways. The module 150 can be implemented in hardware as a module 150-1, such as being implemented as part of one or more processors 152. The module 150-1 can also be implemented as an integrated circuit or by other hardware (such as a programmable gate array). In another example, the module 150 can be implemented as a module 150-2, which is implemented as a 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 to cause the RAN node 170 to perform one or more operations described herein together with the one or more processors 152. Note that the functionality of the module 150 can be distributed, such as being distributed between the DU 195 and the CU 196, or implemented only in the DU 195.

[0022] 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 or 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.

[0023] The one or more buses 157 may be address, data, or control buses, and may include any interconnection mechanism, such as a series of wires on a motherboard or integrated circuit, optical fiber or other optical communication device, wireless channel, etc. For example, the one or more transceivers 160 may be implemented as a remote radio head (RRH) 195 for LTE or a distributed unit (DU) 195 for a gNB implementation for 5G, where other elements of the RAN node 170 may be physically located at a different location from the RRH / DU 195, and the one or more buses 157 may be partially implemented as, for example, a fiber optic cable or other suitable network connection 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 link(s).

[0024] The RAN node / gNB may include one or more TRPs, and the methods described in this document may be applied to these TRPs. Figure 1 RAN node 170 is shown to include 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.

[0025] Relay nodes in NR are called integrated access and backhaul nodes. The mobile termination part of the IAB node facilitates the backhaul (parent link) connection. In other words, the mobile termination part includes the functionality of carrying UE functions. The distributed unit part of the IAB node facilitates the so-called access link (sub-link) connection (i.e., for the access link UE, and in the case of multi-hop IAB, for the backhaul of other IAB nodes). In other words, the distributed unit part is responsible for certain base station functions. The IAB scenario may follow a so-called split architecture, where the central unit hosts the higher layer protocols to the UE and terminates the control plane and user plane interfaces to the 5G core network.

[0026] It is worth noting that the description herein indicates that a "cell" performs functions, but it should be clear that the devices that form the cell can perform these functions. The cell constitutes part of the 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, so that the coverage area of ​​a single base station covers an approximate ellipse or circle. In addition, each cell can correspond to a single carrier, and the base station can use multiple carriers. Therefore, if there are three 120-degree cells and two carriers per carrier, the base station has a total of 6 cells.

[0027] The wireless network 100 may include a network element 190, which may include core network functions, and which provides connectivity to another network, such as a telephone network and / or a data communication network (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 (multiple) access and mobility management functions ((multiple) AMFs) and / or user plane functions ((multiple) UPFs) and / or (multiple) 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 (multiple) network elements 190, and it is noted that both 5G and LTE functions may be supported. The RAN node 170 is coupled to the network element 190 via a link 131. The link 131 may be implemented, for example, as an NG interface for 5G, or as an S1 interface for LTE, or as other suitable interfaces for other standards. The network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (N / WI / F) 180, which are interconnected by 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 functionality 172.

[0028] The wireless network 100 may 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 categorized as external virtualization, which combines many networks or parts of networks into virtual units, and internal virtualization, which provides network-like functions to software containers on a single system. Note that the virtualized entities produced by network virtualization are still implemented to some extent using hardware (such as processors 152 or 175 and memories 155 and 171), and such virtualized entities also produce technical effects.

[0029] Computer readable memories 125, 155, and 171 may be of any type suitable for the local technical environment and may 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-volatile memory, transient memory, fixed memory, and removable memory. Computer readable memories 125, 155, and 171 may be components for performing storage functions. Processors 120, 152, and 175 may be of any type suitable for the local technical environment and may include, as non-limiting examples, one or more of a general-purpose computer, a special-purpose computer, a microprocessor, a digital signal processor (DSP), and a processor based on a multi-core processor architecture. Processors 120, 152, and 175 may be components for performing functions, such as controlling UE 110, RAN node 170, (multiple) network elements 190, and other functions described herein.

[0030] In general, various example embodiments of user equipment 110 may include, but are not limited to, cellular phones, such as smartphones, tablet computers, 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), tablet computers with wireless communication capabilities, head-mounted displays (such as those that implement virtual / augmented / mixed reality), and portable units or terminals that combine 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, a mobile device, a sensor device, etc., which is a device used by a user or a device not used by a user.

[0031] UE 110, RAN node 170 and / or network element(s) 190 (and associated memory, computer program code and modules) may be configured to (e.g., partially) implement the methods described herein. Thus, computer program code 123 of UE 110, module 140-1, module 140-2 and Figure 1 The other elements / features shown in the figure may implement the user equipment related aspects of the examples described herein. Similarly, the computer program code 153 of the RAN node 170, the module 150-1, the module 150-2 and Figure 1 Other elements / features shown in the figure may implement the example gNB / TRP related aspects described herein. Computer program code 173 of network element(s) 190 and Figure 1Other elements / features shown in may be configured to implement the network element related aspects of the examples described herein.

[0032] Having thus introduced a suitable but non-limiting technical context for practicing example embodiments, example embodiments are now described in more detail.

[0033] The examples described in this article are relevant to 3GPP New Radio (NR) physical layer developments in Rel-19 and beyond (e.g., 6G). More specifically, this article describes a new precoder indication method and corresponding UE transmission procedure for simultaneous multi-panel PUCCH transmissions with one or more Transmission Reception Points (TRPs), where TRPs can be deployed in both single (S)-DCI and multiple (m)-DCI manners.

[0034] Figure 2 An example TCI framework for providing a QCL relationship between source (202, 208) and target (206, 212) signals is depicted. In the example TCI framework, a single TCI state can be indicated to a UE, and the TCI state or (multiple) RSs indicated by the TCI state are used for transmission and reception assumptions of PDCCH / PDSCH / CSI-RS and / or PUCCH / PUSCH / SRS. The principle of providing information to a UE to enable estimation of parameters (204, 210) related to reception or transmission of a downlink or uplink signal / channel is accordingly described in Figure 2 is displayed.

[0035] In this example TCI framework, beam indication or TCI state indication (i.e., indicating which TCI state is used for transmission and / or reception assumptions for signals and channels associated with the TCI state) has the following steps (1-3):

[0036] 1. For the serving cell, the TCI state type is configured as joint UL / DL or separate UL / DL. In joint UL / DL, the indicated TCI state is used for uplink and downlink, and is indicated separately in separate DL and UL (one TCI code point indicated in the DCI may include only DL TCI, only UL TCI, or DL ​​and UL TCI states). If the TCI state type is joint, the UE is configured with a single TCI state list using RRC.

[0037] 2. If the TCI state types are separate, the UE is configured with a DL TCI state list and a UL TCI state list. Configuration is done using RRC signaling, while the MAC CE selects and activates up to eight (in Rel-17) TCI code points, one of which may be indicated via DCI. As mentioned earlier, a TCI code point may include only DL TCI states, only UL TCI states, or both DL and UL TCI states.

[0038] 3. To indicate the TCI state (joint) or separate TCI state (UL and DL), the network provides a TCI code point (value in the DCI message) corresponding to the TCI code point in the MAC CE that activates (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).

[0039] Compared with a single (S)-DCI scheme, a simultaneous uplink multi-panel PUSCH scheme based on multiple (M)-DCI with SDM and SFN may be used, aiming to improve throughput and reliability and reduce latency.

[0040] In the SDM-based scheme, different layers / DMRS ports of one PUSCH are separately precoded and transmitted from different UE panels simultaneously.

[0041] In the SFN based transmission scheme, all the same layers / DMRS ports of one PUSCH transmission opportunity are simultaneously transmitted using two different precoders from two different UE panels associated with different TCI states.

[0042] In both SDM and SFN with codebook based precoding, the UE is provided with a separate precoder matrix for each transmit panel in the DCI via two TPMI entries.

[0043] 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 shown, the downlink DCI (e.g., format 1_1 / 1_2) indicates a TCI code point, which includes two TCI states associated with two different TRPs (joint UL and DL or separate UL). UE 110 can apply the indicated TCI state (associated with the code point value) to a single PUCCH resource with a single-layer multi-panel transmission toward two different TRPs (303, 304). In principle, the UE can determine non-codebook based precoding based on the indicated TCI state, where the downlink NZP-CSI-RS / SSB resources are used as spatial QCL-"typeD" sources for PUCCH resources. Therefore, the network does not have the possibility to "control" the applied precoding type (ie codebook / non-codebook) and the precoding vector associated with the antenna panel used for PUCCH transmission, resulting in potential PUCCH demodulation performance degradation, e.g. in terms of coverage.

[0044] 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 transmissions, demodulation and channel estimation performance may be degraded relative to the case where the UE is "forced" to apply PUCCH precoding. In addition, especially in coverage-limited scenarios, it may be beneficial for the network to control panel-specific precoders (e.g., precoder 312 or precoder 314) for simultaneous PUCCH transmissions to achieve enhanced channel estimation and demodulation performance for PUCCH. Therefore, the examples described in this article address the above-mentioned problems and provide solutions accordingly.

[0045] This paper describes a novel precoder indication method for simultaneous multi-panel PUCCH transmission and the corresponding UE transmission process.

[0046] In an example embodiment, the UE reports new capability information related to supporting codebook based and / or non-codebook based simultaneous multi-panel PUCCH transmissions.

[0047] In an example embodiment, the UE is configured at a higher layer to apply the same uplink precoding to STxMP PUCCH with rank restriction (eg, rank 1).

[0048] In one option, a new Boolean information unit (e.g., follow-PUSCH-STxMP (or alternatively, follow-PUSCH-STxMP-Prec)) is configured in various parameters, e.g., higher-level parameters PUCCH-Resource set or PUCCH-Resource (i-iii): i) When follow-PUSCH-STxMP-Prec in the PUCCH-Resource set and multipanelSfnScheme in PUCCH-Config are configured, the UE shall apply the same precoder associated with the 1st SRI and the 2nd SRI (non-codebook) or the 1st TPMI and the 2nd TPMI (codebook). In an example embodiment, the precoder applies a rank restriction, e.g., a rank 1 restriction (i.e., the first layer of the 1st SRI and the first layer of the 2nd SRI (non-codebook) and the first layer of the 1st TPMI and the first layer of the 2nd TPMI (codebook)), as in a recent STxMP PUSCH transmission triggered by, e.g., DCI 0_1 / 0_2 or configured grant type 1 or type 2 w / DCI activation, regardless of the uplink STxMP scheme for PUSCH; ii) when follow-PUSCH-STxMP-Prec is configured in the PUCCH-Resource set, all PUCCH resources in the PUCCH-Resource set are assumed to follow the STxMP PUSCH precoding (as defined above); iii) when follow-PUSCH-STxMP-Prec is configured in the PUCCH-Resource, each PUCCH resource in the PUCCH-Resource set shall independently follow the STxMP PUSCH precoding (as defined above).

[0049] In another option, the higher layer parameter PUCCH-Resource set or PUCCH-Resource is configured with a new Boolean information element follow-PUSCH-STxMP-Prec and a new information element PUCCH-Prec-Type, configured as "nonCodeBook" or "codebook". When follow-PUSCH-STxMP and PUCCH-Prec-Type = "nonCodebook" are configured, the UE shall 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 grant type 1 or type 2 w / DCI activation. When follow-PUSCH-STxMP and PUCCH-Prec-Type = "Codebook" are configured, the UE shall apply the same precoder associated with the 1st TPMI and the 2nd TPMI (codebook) as in the most recent STxMP PUSCH transmission triggered by, for example, DCI 0_1 / 0_2 or configured grant type 1 or type 2 w / DCI activation. In an example embodiment, the precoder applies a rank restriction, such as a rank 1 restriction.

[0050] In an example embodiment, lower layer parameters may be used, such as, for example, MAC-CE or DCI. For example, 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 in N consecutive time slots, where N is configured by the network, the UE is implicitly instructed to apply the same precoding as the most recent SDM / SFN-based STxMP PUSCH to the STxMP PUCCH resource transmission (described in the previous embodiment).

[0051] In another example, when the UE receives DCI 1_1 / 1_2 with an indicated UL TCI state and a new codepoint follow-PUSCH-STxMP with a value of "TRUE", the UE is explicitly instructed to apply the same precoding to the STxMP PUCCH resource transmission as the most recent SDM / SFN-based STxMP PUSCH (described in the previous embodiment).

[0052] In one implementation, an example of a possible implementation of the TS 38.331 specification is defined, the proposed modifications (marked within / ** / ) are defined in the PUCCH-ResourceSet with PUCCH-config. The IE PUCCH-Config is used to configure UE-specific PUCCH parameters applicable to a specific BWP.

[0070]

[0071] In an example embodiment, transmission of one or more physical uplink control channels using one or more precoders associated with SDM / SFN based STxMP PUSCH is based on the configuration, with or without repetition. In an example embodiment, the UE receives the configuration from the network.

[0072] It is worth noting that PUCCH resources may have the same or different periodicities, and various PUCCH formats may be defined according to physical resource allocation, number of bits, etc.

[0073] Figure 4 An example of simultaneous multi-panel PUCCH transmission with follow-PUSCH in PUCCH-ResourceSet configured is shown. When follow-PUSCH-STxMP-Prec in PUCCH-ResourceSet and multipanelSfnScheme in PUCCH-Config are configured, the UE shall apply the same precoder associated with the 1st TPMI and 2nd TPMI (codebook) with rank 1 restriction (1st layer of 1st TPMI and 1st layer of 2nd TPMI codebook) as in the most recent STxMP PUSCH transmission triggered by DCI 0_1 / 0_2.

[0074] like Figure 4 As shown, the joint UL and DL states are indicated at 402 via downlink control information (S-DCI 1_1 / 1_2), and the states are 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 shown at 410. Item 408 shows the transition to the newly indicated UL TCI states, namely 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, namely TCI state #1 and TCI state #2. At 416, the UE applies the same precoding to the STxMP PUCCH as the STxMP PUSCH with rank 1 restriction. Figure 4 The legend shows a UL SRS resource set (418) with using a "codebook", a PDCCH with DL or UL DCI (420), an STxMP PUSCH with codebook-based precoding and multiple TX antenna panels (422), an STxMP PUCCH with codebook-based precoding and multiple TX antenna panels (424), and an STxMP DMRS (426) with codebook-based precoding and multiple TX antenna panels.

[0075] In one implementation, upon receiving an SRI for simultaneous PUSCH transmission based on SDM or SFN, the UE stores the first column (first layer) of the corresponding precoder matrix in a memory. For the next PUCCH transmission, the UE retrieves the precoder from the memory and applies the precoding vector to the corresponding PUCCH transmission.

[0076] When a PUSCH TXConfig is configured with "nonCodebook" and a PUCCH-Config with multipanelsfnScheme "configured" and DCI 1_1 / 1_2 has been detected, the UE separately determines its antenna panel specific precoder for PUCCH transmission based on the calculated channel estimate associated with the downlink reference signal resources (e.g. NZP-CSI-RS or SSB) associated with the indicated TCI state. Due to UE-specific implementation defects, channel reciprocity between downlink and uplink does not fully hold. The received signal experiences equal signal strength on different RF RX paths associated with each antenna panel. However, this is not the case in the case of simultaneous uplink transmissions 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) may share a PA. Due to the different physical distances between the outputs of the PA and the RF TX antenna connectors, there may be different insertions (simply due to wiring) and / or other implementation-specific losses, causing power imbalances between the signals sent via different antenna panels. In order to compensate for this imbalance in simultaneous uplink transmissions, the UE should apply additional antenna panel-specific TX powers to compensate for the implementation-specific insertion losses 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 the path loss estimation used in the standardized uplink TX power control method. In addition, the network assumes that power imbalance does not exist and it is not known by the network in any way or signaling. Therefore, in order 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 between different antenna panels. Of course, the actual applied output power of each antenna may be different from the different path loss gains associated between different TX antenna panels and the target TRP / RX panel on the network side (i.e., the reference signal resources associated with the indicated TCI state). In order to apply implementation specific TX power compensation / equalization between different antenna panels used for simultaneous PUCCH transmission, the following UE steps need to be performed (steps 1-6):

[0077] Step 1: The UE has an understanding of the implementation specific power / insertion loss between different TX antenna panels. These values ​​have been obtained, for example during the manufacturing phase of the UE / device, or there are some UE implementation specific measurements inside the UE. Once these values ​​are known by the UE, they are stored in the UE's memory.

[0078] Step 2: The UE determines different TX antenna panel pair combinations from all TX antenna panels, and selects an "anchor / main" antenna panel and an auxiliary antenna panel for each antenna panel 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 main panel and antenna panel 2 is the auxiliary panel, where panel 2 has a 3dB loss relative to panel 1. For each antenna panel pair, the UE also calculates the power difference among all antenna panels relative to the best antenna panel. Alternatively, the UE selects a main antenna panel among all antenna panels, which has the smallest implementation / insertion loss among all antenna panels. Then, for each antenna panel pair, the power difference for the two antenna panels within the pair relative to the main antenna panel is calculated. In both cases, these values ​​are stored in the UE's memory for each pair.

[0079] Step 3: The UE computes path loss estimates 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.

[0080] Step 4: When two different TCI states are indicated and the UE is configured to apply PUSCH precoding for STxMP PUCCH, the UE applies the same TX antenna panel as for SDM / SFN based STxMP PUSCH transmission for a single PUCCH resource. Before applying a different rank 1 restricted precoder for STxMP PUSCH to each antenna panel, the UE calculates a new path loss estimate, adding the antenna panel specific implementation loss relative to the main antenna panel (global loss for all antenna panels or local loss within a 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]).

[0081] Typically, when two different TCI states are indicated and the UE is configured to apply PUSCH precoding for simultaneous transmission of PUCCH transmissions across multiple antenna arrangements, the UE will apply the same TX antenna arrangement as the SDM / SFN-based PUSCH transmissions across multiple antenna arrangements for a single PUCCH resource. The antenna arrangements (including those for simultaneous transmission of PUSCH transmissions across multiple antenna arrangements and those for simultaneous transmission of PUCCH transmissions across multiple antenna arrangements) may include one or more antenna panels, or the antenna arrangements (including those for simultaneous transmission of PUSCH transmissions across multiple antenna arrangements and those for simultaneous transmission of PUCCH transmissions across multiple antenna arrangements) may include one or more transmission configuration indicator states.

[0082] 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 PUCCH (also taking into account the PRBs associated with PUCCH). This step is calculated for both antenna panels associated with an antenna panel pair.

[0083] Step 6: The UE calculates the total PUCCH TX power by adding the two antenna panel specific power values ​​(calculated in step 5) and checks that the total TX power of PUCCH on both antenna panels does not exceed the total uplink power budget for PUCCH transmissions. If the calculated total power is less than the total TX power budget for PUCCH transmissions, the UE shall apply the calculated uplink power control value to the indicated TCI state and the single PUCCH transmission, otherwise the UE shall apply only the first indicated TCI state and the corresponding calculated uplink power control value to the single antenna panel PUCCH transmission in step 5.

[0084] In an alternative implementation method, the UE scales the elements of the antenna panel specific precoder vector by antenna panel specific implementation values ​​(ie scalar values) instead of equalizing / correcting the uplink power control.

[0085] The examples described herein have multiple technical effects. The methods described herein enable the network to have full control over whether to use precoding and its precoding type (codebook / non-codebook) for STxMP for S-DCI and M-DCI deployments. For codebook-based PUCCH, the method is able to know exactly which precoding vector to apply to PUCCH precoding. Therefore, this enables greater flexibility for the network scheduler to pair different UEs with the same time and frequency resources. From the UE's perspective, the ideas described herein simplifies STxMP PUCCH operations. The methods described herein are applicable to both S-DCI and M-DCI deployments.
