[0003] METHODS AND APPARATUSES FOR FULL POWER TRANSMISSIONS

[0004] Technical Field

[0005] The present disclosure is related to wireless communication and, more specifically, to methods and apparatuses for full power transmissions.

[0006] The present disclosure claims the benefit of and priority to U.S. Provisional Patent Application Serial No. 63 / 596,040, filed on November 3, 2023, entitled “METHOD AND APPARATUS FOR PRECODER INDICATION AND POWER SCALING FOR 8 TX UE IN FULL POWER MODE 2 CODEBOOK-BASED TRANSMISSION,” the content of which is hereby incorporated herein fully by reference into the present application for all purposes.

[0007] Background Art

[0008] Various efforts have been made to improve different aspects of wireless communication for the cellular wireless communication systems, such as the 5thGeneration (5G) New Radio (NR) system, by improving data rate, latency, reliability, and mobility. The 5G NR system is designed to provide flexibility and configurability to optimize network services and types, accommodating various use cases, such as enhanced Mobile Broadband (eMBB), massive Machine-Type Communication (mMTC), and Ultra-Reliable and Low-Latency Communication (URLLC). As the demand for radio access continues to increase, however, there exists a need for further improvements in the art.

[0009] Summery of Invention

[0010] The present disclosure is related to methods and apparatuses for full power transmissions.

[0011] According to a first aspect of the present disclosure, an 8-transmit (8-TX) User Equipment (UE) for full power transmissions is provided. The 8-TX UE includes at least one processor and at least one non-transitory computer-readable medium coupled to the at least one processor. The at least one non-transitory computer-readable medium stores one or more computer-executable instructions that, when executed by the at least one processor, cause the 8-TX UE to receive, from a Base Station (BS), a UE capability enquiry message; and transmit, to the BS, a UE capability message in response to receiving the UE capability enquiry message. The UE capability message includes Uplink (UL) feature set information applicable to a dedicated UL Bandwidth Part (BWP). The UL feature set information includes a first indicator indicating whether the 8-TX UE supports a full power mode 2 and indicating a maximum number of Sounding Reference Signal (SRS) resources in an SRS resource set configured for a Codebook-Based (CB) Physical Uplink Shared Channel (PUSCH) transmission for the full power mode 2, a second indicator indicating whether the 8-TX UE supports SRS configurations with different numbers of antenna ports per SRS resource for the full power mode 2, and a third indicator indicating one or more full power groups capable of delivering full power in the CB PUSCH transmission per band or per band combination for the full power mode 2.

[0012] In some implementations of the first aspect of the present disclosure, the one or more computer-executable instructions, when executed by the at least one processor, further cause the 8-TX UE to receive, from the BS, a CB PUSCH configuration; receive, from the BS, a Downlink Control Information (DCI) format scheduling the CB PUSCH transmission; and perform, based on the CB PUSCH configuration and the DCI format, the CB PUSCH transmission using the full power mode 2.

[0013] In some implementations of the first aspect of the present disclosure, the third indicator includes a field indicating one or more categories of antenna groups and one or more antenna group configurations for each category of the one or more categories of antenna groups.

[0014] In some implementations of the first aspect of the present disclosure, the one or more categories of antenna groups include a first category where the full power transmissions are supported by one antenna group; a second category where the full power transmissions are supported by two antenna groups; and a third category where the full power transmissions are supported by three antenna groups.

[0015] In some implementations of the first aspect of the present disclosure, the number of antenna ports for each SRS resource in the SRS resource set is one, two, four, or eight.

[0016] In some implementations of the first aspect of the present disclosure, each full power group of the one or more full power groups includes an antenna group or a Transmit Precoder Matrix Indication (TPMI) group.

[0017] According to a second aspect of the present disclosure, a method performed by an 8-transmit (8-TX) User Equipment (UE) for full power transmissions is provided. The method includes receiving, from a Base Station (BS), a UE capability enquiry message; and transmitting, to the BS, a UE capability message in response to receiving the UE capability enquiry message. The UE capability message includes Uplink (UE) feature set information applicable to a dedicated UL Bandwidth Part (BWP). The UL feature set information includes a first indicator indicating whether the 8TX UE supports a full power mode 2 and indicating a maximum number of Sounding Reference Signal (SRS) resources in an SRS resource set configured for a Codebook-Based (CB) Physical Uplink Shared Channel (PUSCH) transmission for the full power mode 2; a second indicator indicating whether the 8-TX UE supports SRS configurations with different numbers of antenna ports per SRS resource for the full power mode 2; and a third indicator indicating one or more full power groups capable of delivering full power in the CB PUSCH transmission per band or per band combination for the full power mode 2.

[0018] According to a third aspect of the present disclosure, a Base Station (BS) for managing full power transmissions is provided. The BS includes at least one processor and at least one non-transitory computer-readable medium coupled to the at least one processor. The at least one non-transitory computer-readable medium stores one or more computer-executable instructions that, when executed by the at least one processor, cause the BS to transmit, to an 8-transmit (8-TX) User Equipment (UE), a UE capability enquiry message; and receive, from the 8-TX UE, a UE capability message after transmitting the UE capability enquiry message. The UE capability message includes Uplink (UL) feature set information applicable to a dedicated UL Bandwidth Part (BWP). The UL feature set information includes a first indicator indicating whether the 8TX UE supports a full power mode 2 and indicating a maximum number of Sounding Reference Signal (SRS) resources in an SRS resource set configured for a Codebook-Based (CB) Physical Uplink Shared Channel (PUSCH) transmission for the full power mode 2; a second indicator indicating whether the 8-TX UE supports SRS configurations with different numbers of antenna ports per SRS resource for the full power mode 2; and a third indicator indicating one or more full power groups capable of delivering full power in the CB PUSCH transmission per band or per band combination for the full power mode 2.

[0019] In some implementations of the third aspect of the present disclosure, the one or more computer-executable instructions, when executed by the at least one processor, further cause the BS to transmit, to the 8-TX UE, a CB PUSCH configuration; and transmit, to the 8-TX UE, a Downlink Control Information (DCI) format scheduling the CB PUSCH transmission, thereby enabling the 8-TX UE to perform, based on the CB PUSCH configuration and the DCI format, the CB PUSCH transmission using the full power mode 2.

[0020] In some implementations of the third aspect of the present disclosure, the third indicator includes a field indicating one or more categories of antenna groups and one or more antenna group configurations for each category of the one or more categories of antenna groups.

[0021] In some implementations of the third aspect of the present disclosure, the one or more categories of antenna groups include a first category where the full power transmissions are supported by one antenna group; a second category where the full power transmissions are supported by two antenna groups; and a third category where the full power transmissions are supported by three antenna groups.

[0022] In some implementations of the third aspect of the present disclosure, the number of antenna ports for each SRS resource in the SRS resource set is one, two, four, or eight.

[0023] In some implementations of the third aspect of the present disclosure, each full power group of the one or more full power groups includes an antenna group or a Transmit Precoder Matrix Indication (TPMI) group.

[0204] The following contains specific information related to implementations of the present disclosure. The drawings and their accompanying detailed disclosure are merely directed to implementations. However, the present disclosure is not limited to these implementations. Other variations and implementations of the present disclosure will be obvious to those skilled in the art.

[0205] Unless noted otherwise, like or corresponding elements among the drawings may be indicated by like or corresponding reference numerals. Moreover, the drawings and illustrations in the present disclosure are generally not to scale and are not intended to correspond to actual relative dimensions.

[0206] For consistency and ease of understanding, like features may be identified (although, in some examples, not illustrated) by the same numerals in the drawings. However, the features in different implementations may be different in other respects and shall not be narrowly confined to what is illustrated in the drawings.

[0207] References to “ oonnee implementation,” “ “aann implementation,” “example implementation,” “various implementations,” “some implementations,” “implementations of the present application,” etc., may indicate that the implementation(s) of the present application so described may include a particular feature, structure, or characteristic, but not every possible implementation of the present application necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “in one implementation,” or “in an example implementation,” “an implementation,” do not necessarily refer to the same implementation, although they may. Moreover, any use of phrases like “implementations” in connection with “the present application” aarree nneevveerr meant to characterize that all implementations of the present application must include the particular feature, structure, or characteristic, and should instead be understood to mean “at least some implementations of the present application” includes the stated particular feature, structure, or characteristic.

[0208] The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series, and the equivalent.

[0209] The expression “at least one of A, B and C” or “at least one of the following: A, B and C” means “only A, or only B, or only C, or any combination of A, B and C.” The terms “system” and “network” may be used interchangeably. The term “and / or” is only an association relationship for describing associated objects and represents that three relationships may exist such that A and / or B may indicate that A exists alone, A and B exist at the same time, or B exists alone. The character “ / ” generally represents that the associated objects are in an “or” relationship.

[0210] For the purposes of explanation and non-limitation, specific details, such as functional entities, techniques, protocols, and standards, are set forth for providing an understanding of the disclosed technology. In other examples, detailed disclosure of well-known methods, technologies, systems, and architectures are omitted so as not to obscure the present disclosure with unnecessary details.

[0211] Persons skilled in the art will immediately recognize that any network function(s) or algorithm(s) disclosed may be implemented by hardware, software, or a combination of software and hardware. Disclosed functions may correspond to modules which may be software, hardware, firmware, or any combination thereof.

[0212] A software implementation may include computer executable instructions stored on a computer-readable medium, such as memory or other type of storage devices. One or more microprocessors or general-purpose computers with communication processing capability may be programmed with corresponding executable instructions and perform the disclosed network function(s) or algorithm(s).

[0213] The microprocessors or general-purpose computers may include Application- Specific Integrated Circuits (ASICs), programmable logic arrays, and / or one or more Digital Signal Processor (DSPs). Although some of the disclosed implementations are oriented to software installed and executing on computer hardware, alternative implementations implemented as firmware, as hardware, or as a combination of hardware and software are well within the scope of the present disclosure. The computer-readable medium includes but is not limited to Random Access Memory (RAM), Read Only Memory (ROM), Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), flash memory, Compact Disc Read-Only Memory (CD-ROM), magnetic cassettes, magnetic tape, magnetic disk storage, or any other equivalent medium capable of storing computer-readable instructions.

[0214] A radio communication network architecture such as a Long-Term Evolution (LTE) system, an LTE- Advanced (LTE- A) system, an LTE- Advanced Pro system, or a 5G NR Radio Access Network (RAN) typically includes at least one base station (BS), at least one UE, and one or more optional network elements that provide connection within a network. The UE communicates with the network such as a Core Network (CN), an Evolved Packet Core (EPC) network, an Evolved Universal Terrestrial RAN (E-UTRAN), a 5G Core (5GC), or an internet via a RAN established by one or more BSs.

[0215] A UE may include, but is not limited to, a mobile station, a mobile terminal or device, or a user communication radio terminal. The UE may be a portable radio equipment that includes, but is not limited to, a mobile phone, a tablet, a wearable device, a sensor, a vehicle, or a Personal Digital Assistant (PDA) with wireless communication capability. The UE is configured to receive and transmit signals over an air interface to one or more cells in a RAN.

[0216] The BS may be configured to provide communication services according to at least a Radio Access Technology (RAT) such as Worldwide Interoperability for Microwave Access (WiMAX), Global System for Mobile communications (GSM) that is often referred to as 2G, GSM Enhanced Data rates for GSM Evolution (EDGE) RAN (GERAN), General Packet Radio Service (GPRS), Universal Mobile Telecommunication System (UMTS) that is often referred to as 3G based on basic wideband-code division multiple access (W-CDMA), high-speed packet access (HSPA), LTE, LTE-A, evolved LTE (eLTE) that is LTE connected to 5GC, NR (often referred to as 5G), and / or LTE-A Pro. However, the scope of the present disclosure is not limited to these protocols.

[0217] The BS may include, but is not limited to, a node B (NB) in the UMTS, an evolved node B (eNB) in LTE or LTE-A, a radio network controller (RNC) in UMTS, a BS controller (BSC) in the GSM / GERAN, an ng-eNB in an Evolved Universal Terrestrial Radio Access (E-UTRA) BS in connection with 5GC, a next generation Node B (gNB) in the 5G-RAN, or any other apparatus capable of controlling radio communication and managing radio resources within a cell. The BS may serve one or more UEs via a radio interface.

[0218] The BS may be operable to provide radio coverage to a specific geographical area using multiple cells forming the RAN. The BS may support the operations of the cells. Each cell may be operable to provide services to at least one UE within its radio coverage.

[0219] Each cell (often referred to as a serving cell) may provide services to serve one or more UEs within its radio coverage, such that each cell schedules the DL (and optionally UL resources) to at least one UE within its radio coverage for DL (and optionally UL packet transmissions from the UE). The BS may communicate with one or more UEs in the radio communication system via the plurality of cells.

[0220] A cell may allocate sidelink (SL) resources for supporting the Proximity Service (ProSe) or Vehicle to Everything (V2X) service. Each cell may have overlapped coverage areas with other cells.

[0221] In Multi-RAT Dual Connectivity (MR-DC) cases, the primary cell of a Master Cell Group (MCG) or a Secondary Cell Group (SCG) may be referred to as a Special Cell (SpCell). A Primary Cell (PCell) may include the SpCell of an MCG. A Primary SCG Cell (PSCell) may include the SpCell of an SCG. MCG may include a group of serving cells associated with the Master Node (MN), including the SpCell and optionally one or more Secondary Cells (SCells). An SCG may include a group of serving cells associated with the Secondary Node (SN), including the SpCell and optionally one or more SCells. As described above, the frame structure for NR supports flexible configurations for accommodating various next generation (e.g., 5G) communication requirements, such as Enhanced Mobile Broadband (eMBB), Massive Machine Type Communication (rnMTC), and Ultra-Reliable and Low-Latency Communication (URLLC), while fulfilling high reliability, high data rate, and low latency requirements. The Orthogonal Frequency-Division Multiplexing (OFDM) technology in the 3 GPP may serve as a baseline for an NR waveform. The scalable OFDM numerology, such as adaptive sub-carrier spacing, channel bandwidth, and Cyclic Prefix (CP), may also be used.

[0222] Two coding schemes may be considered for NR, specifically Low-Density Parity-Check (LDPC) code and Polar Code. The coding scheme adaption may be configured based on channel conditions and / or service applications.

[0223] At least the DL transmission data, a guard period, and UL transmission data should be included in a transmission time interval (TTI) of a single NR frame. The respective portions of the DL transmission data, the guard period, and the UL transmission data should also be configurable based on, for example, the network dynamics of NR. SL resources may also be provided in an NR frame to support ProSe services or V2X services.

[0224] Any two or more of the following paragraphs, (sub)-bullets, points, actions, behaviors, terms, or claims described in the present disclosure may be combined logically, reasonably, and properly to form a specific method.

[0225] Any sentence, paragraph, (sub)-bullet, point, action, behaviors, terms, or claims described in the present disclosure may be implemented independently and separately to form a specific method.

[0226] Dependency, e.g., “based on,” “more specifically,” “preferably,” “in one embodiment,” “in some implementations,” etc., in the present disclosure is just one possible example which would not restrict the specific method.

[0227] “A and / or B” in the present disclosure may refer to either A or B, both A and B, or at least one of A and B.

[0228] In this disclosure, “X / Y” may encompass the meanings of “X or Y,” “X and Y,” and “X and / or Y,” as indicated by two or more of the sentences, paragraphs, sub-bullets, points, actions, behaviors, terms, alternatives, aspects, examples, embodiments, or claims described in the following invention(s).

[0229] One aspect of the present disclosure may be applied in various contexts, including communications, communication equipment (such as mobile telephone apparatus, base station apparatus, wireless LAN apparatus, and / or sensor devices), integrated circuits (such as communication chips), and software programs, among others. The terms “an antenna port” and “antenna ports,” as discussed in the present disclosure, may refer to “an antenna port used for transmission of PUSCH(s) / PUCCH(s)” and “antenna ports used for transmission of PUSCH(s) / PUCCH(s),” respectively.

[0230] Some of the terms, definitions, and / or abbreviations included in the present disclosure may either be sourced from existing documents (such as those from ETSI, ITU, or other sources) or may be newly created by experts from the 3 GPP whenever there was a need for a precise vocabulary.

[0231] Examples of some selected terms in the present disclosure are provided as follows.

[0232] Antenna Panel: A conceptual term for a UE antenna implementation. It may be assumed that a panel may be an operational unit for controlling a transmit spatial filter (beam). A panel may typically include multiple antenna elements. In some implementations, a beam may be formed by a panel, and in order to form two beams simultaneously, two panels may be needed. Such simultaneous beamforming by multiple panels may be subject to the UE capability. A similar definition for “panel” may be applicable by applying spatial receiving filtering characteristics. The UE panel information may be derived from the TCI state / UL beam indication information, or from the network signaling.

[0233] Beam: A beam may include a spatial (domain) filtering. In one example, the spatial filtering may be applied in the analog domain by adjusting a phase and / or amplitude of the signal before being transmitted by a corresponding antenna element. In another example, the spatial filtering may be applied in the digital domain by the Multi-Input Multi-Output (MIMO) technique in the wireless communication system. For example, “a UE made a PUSCH transmission by using a specific beam” may mean that the UE made the PUSCH transmission by using the specific spatial / digital domain filter. The “beam” may also be, but is not limited to be, represented as an antenna, an antenna port, an antenna element, a group of antennas, a group of antenna ports, or a group of antenna elements. The beam may also be formed by a certain reference signal resource. In short, the beam may be equivalent to a spatial domain filter through which the EM wave is radiated. Beam information may include details about the selected or utilized beam or spatial filter. In some implementations, the individual beams (e.g., spatial filters) may be used to transmit individual reference signals. Consequently, a beam or beam information may be represented by one or more reference signal resource indices.

[0234] DCI: DCI may include downlink control information, and there may be various DCI formats used in a PDCCH. The DCI format may be a predefined format in which the downlink control information may be packed / formed and transmitted in a PDCCH.

[0235] TCI state: a TCI state may include parameters for configuring a QCL relationship between one or more DL reference signals and a target reference signal set. For example, a target reference signal set may include the DMRS ports of a PDSCH, a PDCCH, a PUCCH, or a PUSCH. The reference signals may include UL or DL reference signals. In NR Rel-15 / 16, the TCI state may be used for a DL QCL indication, whereas the spatial relation information may be used for providing the UL spatial transmission filter information for the UL signal(s) or channel(s). A TCI state may include the information similar to the spatial relation information, which may be used for UL transmission. In other words, from the UL perspective, a TCI state may provide the UL beam information that may indicate the relationship between a UL transmission and the DL or UL reference signals (e.g., the CSI-RS, the SSB, the SRS, and the PTRS).

[0236] HARQ: A functionality that ensures the delivery between peer entities at Layer 1 (e.g., Physical Layer). A single HARQ process may support one Transport Block (TB) when the physical layer is not configured for the downlink / uplink spatial multiplexing, and when the physical layer is configured for downlink / uplink spatial multiplexing, a single HARQ process may support one or more TBs. There may be one HARQ entity per serving cell. Each HARQ entity may support a parallel (number of) DL and UL HARQ process.

[0237] In the present disclosure, although the term “gNB” may have been used throughout the document, it should be understood that the term “gNB” may be replaced by any other type ofBS (e.g., an eNB).

[0238] Multi-Input Multi-Output (MIMO) is one of the key technologies in NR systems and has been successful in commercial deployments. Over the past ten years, the MIMO features may have been investigated and specified for both frequency division duplexing (FDD) and time division duplexing (TDD) systems, with a focus on downlink MIMO operation. Currently, it may be important to identify and specify necessary enhancements for uplink MIMO. At the same time, enhancements to downlink MIMO may be needed to facilitate the use of a large antenna array. These enhancements should apply not only to frequency range 1 (FR1) but also to frequency range 2 (FR2). Such improvements may be necessary to meet the evolving demands of NR deployments. These enhancements may include the study and, if justified, the specification of uplink DMRS, SRS, SRI, and TPMI (including codebook) improvements to enable 8-TX UL operation, supporting 4 or more layers per UE in the uplink, targeting customer premises equipment (CPE), fixed wireless access (FWA), vehicles, and industrial devices. Potential restrictions on the scope of this objective, including coherence assumptions and full / non-full power modes, may be identified as part of the study. The 8-TX UL operation may refer to a UE with eight antenna ports for uplink transmission.

[0239] MIMO technology may be an effective way to increase the throughput of NR systems, such as by increasing the maximum number of transmission layers and / or utilizing beamforming techniques. The enhancement of uplink (UL) MIMO operation in the NR system may continue to evolve based on ongoing hardware advancements. As a result, the scenario of a UE with 8-TX may become increasingly feasible. In this scenario, how to indicate a precoder for the UE may become a potential issue. The size of the supported codebook subset(s), corresponding to different coherence conditions, may increase due to the growing number of antenna ports used for data transmission. Therefore, the nested indication for TPMI may no longer be suitable, and a new TPMI indication mechanism may need to be developed. The nested indication for TPMI may refer to a configuration where a codebook subset may be applied for at least one of three coherence conditions. These conditions include full coherence, partial coherence, and non-coherence.

[0240] Additionally, the efficiency of uplink (UL) transmission power utilization may become a potential issue as the number of antenna ports for data transmission increases. The UL transmission power for a UE may be configured by the BS (e.g., gNB), where the configured UL transmission power may be distributed among the antenna ports used for data transmission. The UE may divide all or some of the configured UL transmission power equally among the antenna ports on which the UE transmits PUSCH with non-zero power. When the total transmission power across all antenna ports is equal to the configured UL transmission power, this is referred to as a full power transmission (FPT). The FPT may be performed using different approaches depending on the UE’s capability. One of the methods to achieve the FPT may be called full power mode 2, where full power mode 2 may achieve the FPT by informing the candidate precoder (s) to the gNB / NW through the UE and by adjusting the power scaling factor by the UE. However, for an 8-TX UE, how to inform the candidate precoder(s) and how to adjust the power scaling factor may still be unclear.

[0241] Accordingly, this disclosure may propose a mechanism for 8-TX PUSCH transmissions that may include approaches for indicating the candidate precoder(s) and calculating the power scaling factor, achieving the FPT in full power mode 2 operation.

[0242] The terms “an antenna port” and “antenna ports” used in the present disclosure may be referred to as “an antenna port used for the transmission of PUSCH(s) / PUCCH(s)” and “antenna ports used for the transmission of PUSCH(s) / PUCCH(s),” respectively. Additionally, the term “an antenna group” used in the present disclosure may be referred to as “a group including more than one antenna port, where all antenna ports in the group are fully coherent.” Furthermore, the term “an antenna element” used in the present disclosure may be referred to as “an antenna element including two cross-polarized antenna ports.”

[0243] Rel-15 4-TX codebooks may include codebooks used for uplink CB transmission when the UE is equipped with four antenna ports or when the UE is configured with an SRS resource set including at least one 4-port SRS resource. The UE may be indicated with an SRI associated with the 4-port SRS resource by the BS / NW.

[0244] Rel-15 2-TX codebooks may include codebooks used for uplink CB transmission when the UE is equipped with two antenna ports or when the UE is configured with an SRS resource set including at least one 2 -port SRS resource. The UE may be indicated with an SRI associated with the 2 -port SRS resource by the BS / NW.

[0245] Codebook-based (CB) Transmission

[0246] A UE may include a device with eight antenna ports (e.g., an 8-TX UE). The CB transmission may represent that the UE transmits data on the PUSCH using a precoder indicated by the BS / NW from a configured codebook subset. The CB transmission may be applicable to a dedicated uplink BWP. The UE may perform the CB transmission on the PUSCH upon receiving a particular IE (e.g., the PUSCH-Config IE). The PUSCH-Config IE may include a particular field (e.g., the txConfig field) set to the “codebook” by the BS / NW.

[0247] A configured maximum rank may represent the maximum number of transmission layers that the UE is configured or indicated, by the BS / NW, to perform the PUSCH transmission applicable to a dedicated UL BWP.

[0248] In some implementations, the UE may be configured with a maximum rank applicable to the PUSCH transmission scheduled by the DCI format 0_1. The UE may be configured with the maximum rank via the RRC signaling received from the BS / NW. The RRC signaling may include the PUSCH-Config IE that includes a particular field (e.g., maxRank field).

[0249] In some implementations, the UE may be configured with a maximum rank applicable to the PUSCH transmission scheduled by the DCI format 0_2. The UE may be configured with the maximum rank via the RRC signaling received from the BS / NW. The RRC signaling may include the PUSCH-Config IE that includes a particular field (e.g., the maxRankDCI-0-2 field).

[0250] In some implementations, a UE may be configured with a maximum rank applicable to the PUSCH transmission scheduled by the DCI format 0_1 / 0_2. The UE may be configured with the maximum rank via the RRC signaling received from the BS / NW. The RRC signaling may include a particular field (e.g., the maxRank / maxRankDCI-0-2 field). The maxRank / maxRankDCI-0-2 field may be in an integer format. The maxRank / maxRankDCI-0-2 field may be set to a value of up to eight / four.

[0251] A configured codebook subset may represent the precoder coherence that the UE is indicated / configured, by the BS / NW, to perform the PUSCH transmission applicable to a dedicated UL BWP.

[0252] In some implementations, the UE may be configured with a codebook subset applicable to the PUSCH transmission scheduled by the DCI format 0_l. The UE may be configured with the codebook subset via the RRC signaling received from the BS / NW. The RRC signaling may include the PUSCH-Config IE that includes a particular field (e.g., the codebookSubset field).

[0253] In some implementations, the UE may be configured with a codebook subset applicable to the PUSCH transmission scheduled by the DCI format 0_2, The UE may be configured with the codebook subset via the RRC signaling received from the BS / NW. The RRC signaling may include the PUSCH-Config IE that includes a particular field (e.g., the codebookSubsetDCI-0-2 field).

[0254] In some implementations, a UE may be configured with a codebook subset applicable to the PUSCH transmission scheduled by the DCI format 0_1 / 0 2. The UE may be configured, by the BS / NW, with the codebook subset via the RRC signaling. The RRC signaling may include a particular field (e.g., the codebookSubset / codebookSubsetDCI-0-2 field). The codebookSubset / codebookSubsetDCI-0-2 field may be in an enumerated format. The codebookSubset / codebookSubsetDCI-0-2 field may be set to a coherence state (e.g., Type A, B, C, D, or E).

[0255] Type A may represent that the UE is indicated / configured, by the BS / NW, with the non-coherent precoders (e.g., Ng=8). Type B may represent that the UE is indicated / configured, by the BS / NW, with the full-coherent precoders (e.g., Ng=1) applicable to (N1,N2)=:(4, 1). Type C may represent that the UE is indicated / configured, by the BS / NW, with the full-coherent precoders (e.g., Ng=l) applicable to (N1,N2)=(2,2). Type D may represent that the UE is indicated / configured, by the BS / NW, with partial-coherent precoders, where each partial-coherent precoder may be applicable to Ng=2. Type E may represent that the UE may be indicated / configured, by the BS / NW, with the partial-coherent precoders, where each partial-coherent precoder may be applicable to Ng=4. Ngis the number of antenna groups, Ni is the number of antenna elements in the first dimension, and N2is the number of antenna elements in the second dimension. The type of the codebook subsets that the BS / NW configures to the UE may depend on the UE’ capabilities reported by the UE.

[0256] The UE may be indicated / configured, via the RRC signaling / DCI received from the BS / NW, with a precoder for the PUSCH (e.g., a CB PUSCH) transmission applicable to a dedicated UL BWP. The UE may be indicated / configured, by the BS / NW, with the precoder based on how the PUSCH transmission is scheduled. The PUSCH transmission may be scheduled, by the BS / NW, based on the following three ways: (i) dynamic grant (DG), configured grant type I (CG Type I), and configured grant type II (CG Type II).

[0257] If the PUSCH transmission is scheduled by the DG, the UE may receive information associated with a precoder via the DCI format 0_1 / 0_2 with the CRC scrambled by the C-RNTI. If the PUSCH transmission is scheduled by the CG Type II, the UE may receive information associated with a precoder via the DCI format 0_1 / 0_2 with the CRC scrambled by the CS-RNTI. If the PUSCH transmission is scheduled by the CG Type I, the UE may receive information associated with a precoder via the RRC signaling that includes a particular IE (e.g., the ConfiguredGrantConfig IE) including a particular field (e.g., the rrc-ConfiguredGrant field).

[0258] In some implementations, if the UE is indicated, by the BS / NW, that (i) the usage of the applied SRS resource set is set to “codebook” (e.g., which may mean that the SRS resource set is configured for a CB UL transmission, such as a CB PUSCH), (ii) the SRS resource set includes at least one SRS resource with eight antenna ports, (iii) the txConfig field is set to “codebook,” and (iv) the configured codebook subset is set to Type A / B / C / D / E, the UE may be jointly indicated / configured, via the RRC signaling / DCI received from the BS / NW, with the TPMI(s) and a number of transmission layers. The BS / NW may indicate to the UE an index that indicates, from a dedicated table, the combination of the number of transmission layers and the TPMI(s). For example, if the UE is indicated / configured with an index indicating the combination of the TPMI equal to four and the number of transmission layers equal to three, the UE may determine that three layers need to be transmitted on the PUSCH and the indicated precoder corresponds to these three layers with the TPMI of four.

[0259] In some implementations, if the UE is indicated, by the BS / NW, that (i) the usage of the applied SRS resource set is set to “codebook,” (ii) the SRS resource set includes at least one SRS resource with eight antenna ports, (iii) the txConfig field is set to “codebook,” and (iv) the configured codebook subset is set to Type D, the UE may be jointly indicated / configured, via the RRC signaling / DCI received from the BS / NW, with a number of transmission layers, one or two TPMI(s), and layer splitting information (e.g., as illustrated in Table 1, as indicated later in the disclosure). The BS / NW may indicate to the UE an index indicating information (e.g., the TPMI(s) and the number of transmission layer(s)) within a dedicated table. The dedicated table may be predefined or configured to the UE via the RRC signaling. The indicated TPMI(s) may be referred to as one or two full-coherent precoders selected from the Rel-15 4-TX codebook.

[0260] In some implementations, if the UE is indicated, by the BS / NW, that (i) the usage of the applied SRS resource set is set to “codebook,” (ii) the SRS resource set includes at least one SRS resource with eight antenna ports, (iii) the txConfig field is set to “codebook,” and (iv) the configured codebook subset is set to Type E, the UE may be jointly indicated / configured, via the RRC signaling / DCI received from the BS / NW, with a number of transmission layers, one, two, three, or four TPMI(s), and layer splitting information (e.g., as illustrated in Table 2, as indicated later in the disclosure). The BS / NW may indicate to the UE an index indicating information (e.g., the number of transmission layers and the layer splitting information) within a dedicated table. The dedicated table may be predefined or configured to the UE via the RRC signaling. The indicated TPMI(s) may be referred to as one, two, three, or four full-coherent precoders selected from the Rel-15 2-TX codebook.

[0261] The layer splitting information may include a four-tuple selected from Table 2, where the four-tuple may indicate the number of transmission layers assigned to each antenna group. The first element in the four-tuple may indicate the number of transmission layers assigned to the first antenna group, the second element in the four-tuple may indicate the number of transmission layers assigned to the second antenna group, the third element in the four-tuple may indicate the number of transmission layers assigned to the third antenna group, and the fourth element in the four-tuple may indicate the number of transmission layers assigned to the fourth antenna group.

[0262] For example, if the UE is indicated or configured with an index indicating that the TPMI is equal to two, the number of transmission layers is equal to one, and the selected four-tuple is (1,0, 0,0), and the UE may select, from the Rel-15 2-TX codebook, a precoder with one layer corresponding to the TPMI of two. The UE may then perform, based on the selected precoder, the CB PUSCH transmission on the first antenna group.

[0263] In some implementations, a dedicated table may only include the precoders applicable to the corresponding codebook subset. The layer splitting information indicated by the dedicated table may include a two-tuple / four-tuple indicating the number of transmission layers assigned to two / four antenna groups. For example, if a UE is configured with two antenna groups, the UE may obtain, based on the dedicated table, two numbers of transmission layers corresponding, respectively, to two antenna groups. If a UE is configured with four antenna groups, the UE may obtain, based on the dedicated table, two numbers of transmission layers corresponding to two antenna groups respectively.

[0264] The UE may be preconfigured with at least one dedicated table used for indicating the TPMI(s) and the number of transmission layers. The UE may determine, based on the RRC signaling and / or DCI received from the BS / NW, a dedicated table indicating the TPMI(s) and the number of transmission layers. For DG, the dedicated table applicable to a dedicated UL BWP may be determined by the UE based on the PUSCH-Config IE and / or the DCI format 0_1 / 0_2 received from the BS / NW. The BS / NW may indicate to the UE an index indicating the number of transmission layers and the TPMI(s) via a particular field (e.g., the Precoding information and number of layers field or the Second Precoding Information field) included in the DCI format 0_ 1 / 0_2.

[0265] In some implementations, the UE may determine a dedicated table indicating the TPMI(s) and the number of transmission layers, based on one or more particular fields (e.g., the maxRank / maxRankDCI-0-2 field, the txConfig field, the transformPrecoder field, and / or the codebookSubset / codebookSubsetDCI-0-2 field) in the PUSCH-Config IE and one or more particular fields (e.g., the SRS resource indicator field and / or the SRS resource set indicator field) in DCI format 0_1 / 0_2.

[0266] In some implementations, the UE may determine the TPMI(s) and the number of transmission layers based on the index indicated by the BS / NW and the dedicated table determined by the UE. In some implementations, the dedicated table determined by the UE may indicate that the number of transmission layers corresponding to the higher index is greater than or equal to the number of transmission layers corresponding to the lower index. In some implementations, the dedicated table determined by the UE, may include one or more indices for each transmission layer.

[0267] For a dedicated table, the number of indices indicating the number of transmission layers and the TPMI(s) may increase due to the growing number of antenna ports used for the PUSCH transmission. Consequently, the bitwidth of the corresponding field within the DCI format 0_l / 0_2 may also increase. Therefore, how to reduce signaling overhead by decreasing the bitwidth may be considered.

[0268] One possible solution is that the UE may determine the bitwidth of the corresponding field based on a configured field (e.g., maxRank / maxRank-0-2 field) included in the PUSCH-Config IE applicable to a dedicated UL BWP. In some implementations, if the UE determines a dedicated table based on the DCI / RRC signaling received from the BS / NW, the UE may determine, based on the maxRank / maxRank-0-2 field included in the PUSCH-Config IE, the bitwidth of the corresponding field associated with the number of transmission layers and the TPMI(s). The indices may be ignored if the indices indicate the number of transmission layers greater than the value of the maxRank / maxRank-0-2 field. For example, if (i) the UE is configured, by the BS / NW, with the maxRank / maxRank-0-2 field, (ii) the value of the maxRank / maxRank-0-2 field is equal to two, and (iii) the number of indices corresponding to the transmission layers less than three is equal to x, the bitwidth of the corresponding field may be equal to

[0269] Another possible solution is that a dedicated table determined by the UE may be applied for one single value of the maxRank / maxRank-0-2 field. In some implementations, if the UE determines a dedicated table based on the DCI / RRC signaling received from the BS / NW, the UE may determine, based on the maxRank / maxRank-0-2 field included in the PUSCH-Config IE, the bitwidth of the corresponding field associated with the number of transmission layers and the TPMI(s). The bitwidth may be determined based on the maximum index in the dedicated table.

[0270] Full Power Transmission

[0271] The full power transmission may represent that a UE performs the PUSCH transmission on the active BWP b of the carrier f of the cell c using all the calculated PUS CH transmit power where i includes the PUSCH transmission occasion index, j includes the parameter set configuration index, qdincludes the reference index for obtaining the downlink pathloss estimate for the PUSCH and the PUCCH, and / includes the PUSCH power control adjustment state index. The may pe the pnear value of the calculated PUSCH transmit power

[0272] Without any full power design, the UE may split the calculated PUSCH transmit power equally across the antenna ports on which the UE transmits the PUSCH with non-zero power, where α includes a power scaling factor. In some implementations, α may be equal to the ratio of the number of antenna ports with a non-zero PUSCH transmission power to the maximum number of SRS ports supported by the UE in an SRS resource.

[0273] An antenna port with non-zero transmit power may indicate that the corresponding row of the indicated precoding matrix has at least one non-zero element in all the columns. Additionally, the full power transmission may be achieved when (i) the number of SRS ports of the indicated SRS resource is equal to the maximum number of SRS ports supported by the UE in an SRS resource, and (ii) the number of antenna ports with a non-zero PUSCH transmission power is equal to the number of SRS ports of the indicated SRS resource.

[0274] In order to efficiently utilize the transmit power three full power modes may be introduced. Each full power mode may correspond to a capability associated with the output power of the transmission (TX) chains (e.g., the power amplifiers (PAs)) reported by the UE. For the first mode, called full power mode, the full power transmission may be performed by modifying the calculation of α. In the first mode, the output power of each PA of the UE may reach the full power (e.g., For the second mode, called full power mode 1, the full power transmission may be performed by introducing an additional TPMI in the configured codebook subset. In the second mode, the output power of each PA of the UE may not reach the full power. For the third mode, called full power mode 2, the full power transmission may be performed by indicating the full power TPMI(s) / antenna groups and modifying the calculation of a. In the third mode, the output power of some of the PAs of the UE may reach the full power.

[0275] The full power mode 2 may be performed by the UE for the CB PUS CH transmission if the gNB / NW transmits the related configuration to the UE via the RRC signaling. The UE may perform the full power mode 2 for the CB PUSCH transmission if the gNB / NW indicates / configures a precoder to the UE, where the precoder may belong to the full power TPMI(s) / antenna groups reported by the UE in the UE’s capability.

[0276] In some implementations, if the UE receives a UE capability enquiry message (which is also referred to as UECapabilityEnquiry message in the present disclosure) from the gNB / NW via the RRC signaling, the UE may transmit a UE capability message (which is also referred to as UECapabilitylnformation message in the present disclosure) supporting the full power mode 2 to the gNB / NW via the RRC signaling, where the UECapabilitylnformation message may include three fields (e.g., the first field eight-tx-ul-FullPwrMode2-MaxSRS-ResInSet, the second field eight-tx-ul-FullPwrMode2-SRSConfig-diffNumSRSPorts, and the third field eighl-tx-ul-FullPwrMode2-FullPwrGroup), within the UL feature set information (e.g., the FeatureSetUplink IE). Moreover, the first field eight-tx-ul-FullPwrMode2-MaxSRS-ResInSet may indicate the (UE-supported) maximum number of SRS resources in an SRS resource set with usage set to “codebook" for the 8-TX uplink full power mode 2 operation (e.g., in which the UE may apply the full power mode 2 to perform the CB UL transmission, such as a CB PUSCH), the second field eight-tx-ul-FullPwrMode2-SRSConfig-diffNumSRSPorts may indicate that the UE supports the SRS configuration with a different number of antenna ports per SRS resource for the 8-TX uplink full power mode 2 operation, and the third field eight-tx-ul-FullPwrMode2-FullPwrGroup may indicate that the UE supports the full power group(s) which deliver full power, where the full power group(s) may represent, or may include, the antenna / TPMI group(s).

[0277] In some implementations, the eight-tx-ul-FullPwrMode2-FullPxvrGroup field may indicate the UE-supported antenna group which delivers full power in the CB PUSCH transmission per band or per band combination for the full power mode 2 operation, and the eight-tx-ul-FullPwrMode2-FullPwrGroup field (included in the UECapabilitylnformation message) may include a field (e.g., eight PortsTypeE) that indicates one or multiple categories of the number of antenna groups, and one or multiple categories of the antenna group combinations per category of the number of antenna groups. The categories of the number of antenna groups may be divided into the following three types:

[0278] Type I: Full power is supported by one antenna group.

[0279] Type II: Full Power is supported by two antenna groups.

[0280] Type III: Full power is supported by three antenna groups.

[0281] For example, the antenna group combinations may be (x, 0,0,0) and / or (0,x,0,0) and / or (0,0, x,0) and / or (0,0, 0,x) for Type I, where (x, 0,0,0) represents that only the first antenna group may be supported, (0,x,0,0) represents that only the second antenna group may be supported, and so on. Additionally, the antenna group combinations may be (x,x,0,0) and / or (x,0,x,0) and / or (x,0,0,x) and / or (0,x,x,0) and / or (0,x,0,x) and / or (0,0,x,x) for Type II, where (x,x,0,0) represents that the first and second antenna groups may be supported, (x,0,x,0) represents that the first and third antenna groups may be supported, and so on. Furthermore, the antenna group combinations may be (x,x,x,0) and / or (x,x,0,x) and / or (0,x,x,x) for Type III, where (x,x,x,0) represents that the first, second, and third antenna groups may be supported, (x,x,0,x) represents that the first, second, and fourth antenna groups may be supported, and so on.

[0282] In some implementations, there may be three fields (e.g., eightP ortsTypeETypel, eightPortsTypeETypell, eightP ortsTypeETypellI) included in the eightP ortsTypeE field, where Type I may be supported if the eightP ortsTypeETypel field is present, Type II may be supported if the eightPortsTypeETypell field is present, and Type III may be supported if the eightP ortsTypeETypelll field is present.

[0283] In some implementations, a field corresponding to, or including, a 4-bit bitmap may be included in the eightP ortsTypeE field. The TSB of the bitmap may correspond to the Type I supporting status, the second bit may correspond to the Type II supporting status, the third bit may correspond to the Type III supporting status, and the MSB may be a reserved bit. In such a case, Type I may be supported if the LSB is set to ‘1’; otherwise, Type I may not be supported. Additionally, Type II may be supported if the second bit is set to ‘1’; otherwise, Type II may not be supported. Moreover, Type III may be supported if the third bit is set to ‘ 1’; otherwise, Type III may not be supported.

[0284] In some implementations, the field may correspond to, or include, an index that is in the format of INTEGER(0, 1, 2), where Type I may be supported if the field is set to ‘0,’ Type II may be supported if the field is set to ‘1,’ and Type II may be supported if the field is set to ‘2.’

[0285] In some implementations, the field may correspond to, or include, an index that is in the format of ENUMERATED {0, 1, 2, sparel }, where Type I may be supported if the field is set to ‘0,’ Type II may be supported if the field is set to ‘ 1 ,’ and Type II may be supported if the field is set to ‘2.’

[0286] In some implementations, there may be three fields (e.g., eightPortsTypeETypelComb, eightPortsTypeETypellComb, eightPortsTypeETypelllComb) included in the eightPortsTypeE field. The eightPortsTypeETypelComb field may be in the format INTEGER(0, 1, 2, 3) or the format ENUMERATED{0, 1, 2, 3}. In such cases, the antenna group combination (x, 0, 0, 0) may be supported if the eightPortsTypeETypelComb field is set to ‘0,’ the antenna group combination (0, x, 0, 0) may be supported if the eightPortsTypeETypelComb field is set to ‘1,’ the antenna group combination (0, 0, x, 0) may be supported if the eightPortsTypeETypelComb field is set to ‘2,’ and the antenna group combination (0, 0, 0, x) may be supported if the eightPortsTypeETypelComb field is set to ‘3.’

[0287] Additionally, the eightPortsTypeETypellComb field may be in the format INTEGERS, 1, 2, 4, 5) or the format ENUMERATED{0, 1, 2, 3, 4, 5, spare2, sparel}, where the antenna group combination (x, x, 0, 0) may be supported if the eightPortsTypeETypellComb field is set to ‘0,’ the antenna group combination (x, 0, x, 0) may be supported if the eightPortsTypeETypellComb field is set to ‘1,’ the antenna group combination (x, 0, 0, x) may be supported if the eightPortsTypeETypellComb field is set to ‘2,’ the antenna group combination (0, x, x, 0) may be supported if the eightPortsTypeETypellComb field is set to ‘3,’ the antenna group combination (0, x, 0, x) may be supported if the eightPortsTypeETypellComb field is set to ‘4,’ and the antenna group combination (0, 0, x, x) may be supported if the eightPortsTypeETypellComb field is set to ‘5.’

[0288] Moreover, the eightPortsTypeETypelllComb field may be in the format INTEGER(0, 1, 2) or the format ENUMERATED {0, 1, 2, sparel}, where the antenna group combination (x, x, x, 0) may be supported if the eightPortsTypeETypellComb field is set to ‘0,’ the antenna group combination (x, x, 0, x) may be supported if the eightPortsTypeETypellComb field is set to ‘ 1,’ and the antenna group combination (0, x, x, x) may be supported if the eightPortsTypeETypellComb field is set to ‘2.’

[0289] In some implementations, the fields, such as eightPortsTypeETypelComb, eightPortsTypeETypellComb, and eightPortsTypeETypelllComb, may be included in the eightPortsTypeE field. Each field (e.g., eightPortsTypeETypelComb, eightPortsTypeETypellComb, and eightPortsTypeETypelllComb') may correspond to, or include, a 4-bit bitmap, where the LSB of the bitmap may correspond to the first antenna group supporting status, the second bit may correspond to the second antenna group supporting status, the third bit may correspond to the third antenna group supporting status, and the MSB may correspond to the fourth antenna group supporting status. In such a case, the antenna group may be supported if the corresponding bit is set to ‘O’; otherwise the antenna group may not be supported. For the eightPortsTypeETypelComb field, only one of the bits in the 4-bit bitmap may be set to ‘1.’ For the eightPortsTypeETypellComb field, two of the bits in the 4-bit bitmap may be set to ‘1.’ For the eightPortsTypeETypelIIComb field, three of the bits in the 4-bit bitmap may be set to ‘ 1. ’

[0290] In some implementations, the fields, such as eightPortsTypeETypelComb, eightPortsTypeETypellComb, and eightPortsTypeETypelIIComb, may be included in the eightPortsTypeE field. The eightPortsTypeETypelComb field may correspond to, or include, a 4-bit bitmap, where the LSB of the bitmap may correspond to the antenna group combination (x, 0, 0, 0), the second bit may correspond to the antenna group combination (0, x, 0, 0), the third bit may be correspond to the antenna group combination (0, 0, 0, x), and the MSB may correspond to the antenna group combination (0, 0, 0, x). For example, the antenna group combination (x, 0, 0, 0) may be supported if the LSB is set to ‘ 1 ’ ; otherwise, the antenna group combination (x, 0, 0, 0) is not supported. The antenna group combination (0, x, 0, 0) may be supported if the second bit is set to ‘1’; otherwise, the antenna group combination (0, x, 0, 0) is not supported. The antenna group combination (0, 0, x, 0) may be supported if the third bit is set to ‘ 1’; otherwise, the antenna group combination (0, 0, x, 0) is not supported. The antenna group combination (0, 0, 0, x) may be supported if the MSB is set to ‘ 1’; otherwise, the antenna group combination (0, 0, 0, x) is not supported.

[0291] The eightPortsTypeETypellComb field may correspond to, or include, a 7-bit bitmap, where the LSB of the bitmap may correspond to the antenna group combination (x, x, 0, 0), the second bit may correspond to the antenna group combination (x, 0, x, 0), the third bit may be correspond to the antenna group combination (x, 0, 0, x), the fourth bit may be correspond to the antenna group combination (0, x, x, 0), the fifth bit may be correspond to the antenna group combination (0, x, 0, x), and the MSB may be correspond to the antenna group combination (0, 0, x, x). For example, the antenna group combination (x, x, 0, 0) may be supported if the LSB is set to ‘ 1 ’ ; otherwise, the antenna group combination (x, x, 0, 0) is not supported. The antenna group combination (x, 0, x, 0) may be supported if the second bit is set to ‘ 1’; otherwise, the antenna group combination (x, 0, x, 0) is not supported. The antenna group combination (x, 0, 0, x) may be supported if the third bit is set to ‘ 1 ’; otherwise, the antenna group combination (x, 0, 0, x) is not supported. The antenna group combination (0, x, x, 0) may be supported if the fourth bit is set to ‘1’; otherwise, the antenna group combination (0, x, x, 0) is not supported. The antenna group combination (0, x, x, 0) may be supported if the fifth bit is set to ‘ 1’; otherwise, the antenna group combination (0, x, x, 0) is not supported. The antenna group combination (0, 0, x, x) may be supported if the MSB is set to ‘1 ’; otherwise, the antenna group combination (0, 0, x, x) is not supported.

[0292] The eightPortsTypeETypelllComb field may correspond to, or include, a 3 -bit bitmap, where the LSB of the bitmap may correspond to the antenna group combination (x, x, x, 0), the second bit may correspond to the antenna group combination (x, x, 0, x), and the MSB may be correspond to the antenna group combination (0, x, x, x). For example, the antenna group combination (x, x, x, 0) may be supported if the LSB is set to ‘ 1’; otherwise, the antenna group combination (x, x, x, 0) is not supported. The antenna group combination (x, x, 0, x) may be supported if the second bit is set to ‘ 1 ’ ; otherwise, the antenna group combination (x, x, 0, x) is not supported. The antenna group combination (0, x, x, x) may be supported if the MSB is set to ‘ 1’; otherwise, the antenna group combination (0, x, x, x) is not supported.

[0293] In some implementations, the inclusion of the eight-tx-ul-FullPwrMode2-FullPwrGroup field in the signaling may be optional. In some implementations, the inclusion of the eight-lx-ul-FullPwrMode2-FullPwr(jroup field in the signaling may be mandatory.

[0294] In some implementations, the eight-tx-ul-FullPwrMode2-FullPwrGroup field may indicate the UE-supported antenna group that delivers full power in the CB PUSCH transmission per band or per band combination for the full power mode 2 operation. The eight-tx-ul-FullPwrMode2-FullP-wrGroup field included in the UECapabilitylnformation message may include a field (e.g., eightPortsTypeD) corresponding to a bit, where the bit may be used to indicate one of two antenna groups, and the indicated antenna group may deliver full power.

[0295] For example, the UE may indicate that the full power (mode 2) is supported by the first antenna group by setting the field to bit ‘0,’ and the UE may indicate that the full power (mode 2) is supported by the second antenna group by setting the field to bit ‘1.’ In another example, the UE may indicate that the full power (mode 2) is supported by the first antenna group by setting the field to bit ‘ 1’ and the UE may indicate that full power (mode 2) is supported by the second antenna group by setting the field to bit ‘0.’

[0296] In some implementations, the eight-tx-ul-FullPwrMode2-FullPwrGroup field may indicate the UE-supported antenna group(s) that delivers the full power in the CB PUSCH transmission per band or per band combination for the full power mode 2 operation. The eight- tx-ul-FullPwrMode2-FullPwrGroup field included in the UECapabilitylnformation message may include a field (e.g., eightPortsTypeEf corresponding to a 4-bit bitmap, where the bitmap may be used to indicate one / two / three of four antenna groups, and the combination of the indicated antenna group(s) may deliver the full power. In some implementations, the leftmost bit, the rightmost bit, the LSB, or the MSB of the bitmap may refer to the first antenna group, the second leftmost bit or the second MSB may refer to the second antenna group, the third leftmost bit or the third MSB may refer to the third antenna group, and the fourth leftmost bit or the fourth MSB may refer to the fourth antenna group. In some implementations, the value ‘0’ in the bitmap may indicate that the corresponding antenna group is not indicated, and the value ‘ 1 ’ in the bitmap may indicate that the corresponding antenna group is indicated. In some implementations, the UE may set at most three bits to the value ‘1’ and set the remaining bit(s) to the value ‘0.’ In some implementations, the UE may set one, two, or three bits in the bitmap to the value ‘ 1,’ and set the remaining bit(s) to the value ‘0.’ In some implementations, the UE may not be expected to set more than three bits to the value ‘ 1.’ In some implementations, the UE may not be expected to set all four bits to the value ‘ 1.’ In some implementations, the UE may not be expected to set all four bits to the value ‘0.’

[0297] In some implementations, the UE may utilize the bitmap to indicate which antenna group(s) support the full power mode 2. Each bit in the bitmap may correspond to a specific antenna group, where setting a bit to ‘ 1 ’ may indicate that the full power mode 2 is supported by the respective antenna group, and setting a bit to ‘0’ may indicate that the full power mode 2 is not supported by that antenna group. The combination of multiple bits set to ‘ 1’ may represent support for the full power mode 2 across several antenna groups simultaneously.

[0298] For example, the UE may indicate that the full power (mode 2) is supported by the first antenna group by setting the field to the bitmap ‘1000.’ The UE may indicate that the full power (mode 2) is supported by the second antenna group by setting the field to the bitmap ‘0100.’ The UE may indicate that the full power (mode 2) is supported by the third antenna group by setting the field to the bitmap ‘0010.’ The UE may indicate that the full power (mode 2) is supported by the fourth antenna group by setting the field to the bitmap ‘0001.’

[0299] Additionally, the UE may indicate that the full power (mode 2) is supported by the first and second antenna groups by setting the field to the bitmap ‘ 1100.’ The UE may indicate that the full power (mode 2) is supported by the first and third antenna groups by setting the field to the bitmap ‘ 1010.’ The UE may indicate that the full power (mode 2) is supported by the first and fourth antenna groups by setting the field to the bitmap ‘ 1001.’ The UE may indicate that the full power (mode 2) is supported by the second and third antenna groups by setting the field to the bitmap ‘0110.’ The UE may indicate that the full power (mode 2) is supported by the second and fourth antenna groups by setting the field to the bitmap ‘0101.’ The UE may indicate that the full power (mode 2) is supported by the third and fourth antenna groups by setting the field to the bitmap ‘0011.’ Moreover, the UE may indicate that the full power (mode 2) is supported by the first, second, and third antenna groups by setting the field to the bitmap ‘1110.’ The UE may indicate that the full power (mode 2) is supported by the first, second, and fourth antenna groups by setting the field to the bitmap ‘1101.’ The UE may indicate that the full power (mode 2) is supported by the first, third, and fourth antenna groups by setting the field to the bitmap ‘1011.’ The UE may indicate that the full power (mode 2) is supported by the second, third, and fourth antenna groups by setting the field to the bitmap ‘0111.’

[0300] The following examples are similar to the previous ones, but the bit order is reversed. In these examples, the bit positions in the bitmap have been inverted, where the first bit represents the fourth antenna group, and the last bit represents the first antenna group. This change in bit order allows flexibility in representing antenna groups.

[0301] For example, the UE may indicate that the full power (mode 2) is supported by the first antenna group by setting the field to the bitmap ‘0001.’ The UE may indicate that the full power (mode 2) is supported by the second antenna group by setting the field to the bitmap ‘0010.’ The UE may indicate that the full power (mode 2) is supported by the third antenna group by setting the field to the bitmap ‘0100.’ The UE may indicate that the full power (mode 2) is supported by the fourth antenna group by setting the field to the bitmap ‘1000.’

[0302] Moreover, the UE may indicate that the full power (mode 2) is supported by the first and second antenna groups by setting the field to the bitmap ‘0011.’ The UE may indicate that the full power (mode 2) is supported by the first and third antenna groups by setting the field to the bitmap ‘0101.’ The UE may indicate that the full power (mode 2) is supported by the first and fourth antenna groups by setting the field to the bitmap ‘ 1001.’ The UE may indicate that the full power (mode 2) is supported by the second and third antenna groups by setting the field to the bitmap ‘0110.’ The UE may indicate that the full power (mode 2) is supported by the second and fourth antenna groups by setting the field to the bitmap ‘1010.’ The UE may indicate that the full power (mode 2) is supported by the third and fourth antenna groups by setting the field to the bitmap ‘ 1100.’

[0303] In addition, the UE may indicate that the full power (mode 2) is supported by the first, second, and third antenna groups by setting the field to the bitmap ‘0111.’ The UE may indicate that the full power (mode 2) is supported by the first, second, and fourth antenna groups by setting the field to the bitmap ‘1011.’ The UE may indicate that the full power (mode 2) is supported by the first, third, and fourth antenna groups by setting the field to the bitmap ‘ HOL’ The UE may indicate that the full power (mode 2) is supported by the second, third, and fourth antenna groups by setting the field to the bitmap ‘1110.’

[0304] In some implementations, the eight-tx-ul-FullPwrMode2-FullPwrGroup field may indicate the UE-supported antenna group(s) that delivers the full power in the CB PUS CH transmission per band or per band combination for the full power mode 2 operation. The eight-tx-ul-FullPwrMode2-FullPwrGroup field included in the UECapabilitylnformation message may include a field (e.g., eightPortsTypeE) corresponding to, or including, an index, where the index may be used to indicate one / two / three of four antenna groups, and the combination of the indicated antenna group(s) may deliver the full power. The index may include, or consists of, four bits (e.g., a 4-bit bitmap). Additionally or alternatively, the index may be in the format of INTEGER(0, 1, 2, ..., 13). Additionally or alternatively, the index may be in the format of ENUMERATED {0, 1, 2, 3, ..., 13, spared, sparel }.

[0305] Specifically, the UE may use the index and / or the corresponding bitmap to indicate which antenna group (s) support the full power mode 2. Each index may correspond to a specific combination of antenna groups, and the bitmap may provide a binary representation of the supported groups. The relationship between the index value and the corresponding bitmap may be based on a 4-bit binary representation. Each index value may correspond to a 4-bit binary number, where each bit in the bitmap represents an antenna group. In the bitmap, a bit set to ‘ 1 ’ may indicate that the corresponding antenna group supports the full power mode 2, while a bit set to ‘0’ may indicate that it does not. The binary value of the bitmap may be equal to the index value.

[0306] For example, the UE may indicate that the full power (mode 2) is supported by the first antenna group by setting the field to an index equal to 0 or / and the corresponding bitmap to ‘0000.’ The UE may indicate that the full power (mode 2) is supported by the second antenna group by setting the field to an index equal to 1 or / and the corresponding bitmap to ‘0001.’ The UE may indicate that the full power (mode 2) is supported by the third antenna group by setting the field to an index equal to 2 or / and the corresponding bitmap to ‘0010.’ The UE may indicate that the full power (mode 2) is supported by the fourth antenna group by setting the field to an index equal to 3 or / and the corresponding bitmap to ‘0010.’ The UE may indicate that the full power (mode 2) is supported by the first and second antenna groups by setting the field to an index equal to 4 or / and the corresponding bitmap to ‘0011.’ The UE may indicate that the full power (mode 2) is supported by the first and third antenna groups by setting the field to an index equal to 5 or / and the corresponding bitmap to ‘0100.’ The UE may indicate that the full power (mode 2) is supported by the first and fourth antenna groups by setting the field to an index equal to 6 or / and the corresponding bitmap to ‘0101.’ The UE may indicate that the full power (mode 2) is supported by the second and third antenna groups by setting the field to an index equal to 7 or / and the corresponding bitmap to ‘0110.’ The UE may indicate that the full power (mode 2) is supported by the second and fourth antenna groups by setting the field to an index equal to 8 or / and the corresponding bitmap to ‘0111.’ The UE may indicate that the full power (mode 2) is supported by the third and fourth antenna groups by setting the field to an index equal to 9 or / and the corresponding bitmap to ‘ 1000.’ The UE may indicate that the full power (mode 2) is supported by the first, second, and third antenna groups by setting the field to an index equal to 10 or / and the corresponding bitmap to ‘ 1001.’ The UE may indicate that the full power (mode 2) is supported by the first, second, and fourth antenna groups by setting the field to an index equal to 11 or / and the corresponding bitmap to ‘ 1010.’ The UE may indicate that the full power (mode 2) is supported by the first, third, and fourth antenna groups by setting the field to an index 12 or / and the corresponding bitmap to ‘ 1011.’ The UE may indicate that full power (mode 2) is supported by the second, third, and fourth antenna groups by setting the field to an index equal to 13 or / and the corresponding bitmap to ‘1100.’

[0307] In some implementations, the eight-tx-ul-FullPwrMode2-FullPwrGroup field may indicate the UE-supported antenna group(s) that delivers the full power in the CB PUSCH transmission per band or per band combination for the full power mode 2 operation. The eight-tx-ul-FullPwrMode2-FullPwrGroup field included in the UECapabilitylnformation message may include a field (e.g., eightPortsTypeE) corresponding to, or including, an index of a table, where the index may be used to indicate one / two / three of four antenna groups, and the combination of the indicated antenna group(s) may deliver the full power. Furthermore, the index may refer to, or correspond to, a particular entry in the table. The index may be in the format of INTEGER(0, 1, 2, ..., 13) or in the format of ENUMERATED {0, 1, 2, 3, ..., 13, spare2, sparel}.

[0308] For example, the UE may indicate that the full power (mode 2) is supported by the first antenna group by setting the field to an index equal to 0 or / and corresponding to the first entry in the table. The UE may indicate that the full power (mode 2) is supported by the second antenna group by setting the field to an index equal to 1 or / and corresponding to the second entry in the table.

The index may be in the format of INTEGER(0...7) or in the format of ENUMERATED {0, 1, 2, 3, 4, 5, 6, 7}. Additionally or alternatively, the index may be in a 3 -bit format.

[0310] For example, the UE may indicate that the full power (mode 2) is supported by the first antenna port by setting the field to an index equal to 0. Additionally or alternatively, the UE may indicate that the full power (mode 2) is supported by the first antenna port by setting the field to ‘000.’

[0311] For example, the UE may indicate that the full power (mode 2) is supported by the second antenna port by setting the field to an index equal to 1. Additionally or alternatively, the UE may indicate that the full power (mode 2) is supported by the second antenna port by setting the field to ‘001.’

Additionally or alternatively, the UE may indicate that the full power (mode 2) is supported by the eighth antenna port by setting the field to ‘ 111. ’

[0318] In some implementations, the eight-tx-ul-FullP-wrMode2-FullPwrGroup field may indicate the UE-supported antenna group(s) that delivers the full power in the CB PUSCH transmission per band or per band combination for the full power mode 2 operation.

The index may correspond to the row index of a table. The table with multiple entries may include the information of the 8-port noncoherent precoder(s).

[0319] For example, the first entry of the table may correspond to the first antenna port for delivering / using the full power (mode 2) (e.g., the full power (mode 2) with the first antenna port).

[0321] [Table 1]

[0322] The index may set to one of 4-port partial-coherent precoders from G0 to G6.

[0323] In some implementations, the eight-tx-ul-FullP-wrMode2-FullPwrGroup field may indicate the-UE supported antenna group(s) that delivers the full power in the CB PUSCH transmission per band or per band combination for the full power mode 2 operation.

The eighl-tx-ul-FullPwrMode2-FullPwrGroup field included in the UECapabilitylnformation message may include a field (e.g., twoPorts') corresponding to, or including, a 2 -bit bitmap, where the bitmap may be used to indicate one or two 2-port noncoherent precoders, and the indicated precoder(s) may be used to deliver the full power. For example, the first bit of the bitmap may correspond to the precoder if the precoder is supported by the UE, the first bit may be set to 1 ; otherwise, the first bit may be set to 0. Additionally, the second bit may correspond to the precoder if the precoder is supported by the UE, the second bit may be set to 1 ; otherwise, the second bit may be set to 0.

[0329] In some implementations, in response to the UE receiving a UECapabilityEnquiry message from the gNB / NW via RRC signaling, the UE may transfer or transmit, to the gNB / NW, RRC signaling including a UECapabilitylnformation message indicating that the UE supports the full power mode 2.

[0330] Moreover, the eight-tx-ul-FullPwrMode2-MaxSRS-ResInSet field may indicate the (UE-supported) maximum number of SRS resources in an SRS resource set with usage set to “codebook” for the 8-TX uplink full power mode 2 operation. The eight-tx-ul-FullPwrMode2-SRSConfig-diffNumSRSPorts field may indicate that the UE supports an SRS configuration with different number of antenna ports per SRS resource for the 8-TX uplink full power mode 2 operation. In some implementations, the ul-FullPwrMode2-TPMIGroup field within the FeatureSetUplink IE may include the information associated with one or two precoders for two antenna ports, the information associated with at least one precoder for four antenna ports, and / or the information associated with at least one precoder for eight antenna ports. The UE may perform the full power transmission if one of the corresponding precoders is indicated / configured and the full power mode 2 is configured by the gNB / NW.

[0331] In some implementations, if the UE reports to the gNB / NW that the codebook subset Type B / C is supported and that full power mode 2 is supported, the UE may further report at least one of the following: an eight-port TPMI group used for Type D / E, an eight-port TPMI group used for Type A, a four-port partial-coherent TPMI group (e.g., selected from G0-G3), a four-port noncoherent TPMI group (e.g., selected from G0-G6), and at least one two-port TPMI group (e.g., 2 -bit bitmap).

[0333] In some implementations, if the UE reports to the gNB / NW that the codebook subset Type A is supported and that full power mode 2 is supported, the UE may report at least one of the following: an eight-port TPMI group used for Type A, a four-port partial-coherent TPMI group (e.g., selected from G0-G3), a four-port noncoherent TPMI group (e.g., selected from G0-G6), and / or at least one two-port TPMI group (e.g., 2-bit bitmap).

[0334] In some implementations, in response to the UE receiving a UECapabilityEnquiry message from the gNB / NW via RRC signaling, the UE may transfer / transmit a UECapabilitylnformation message to the gNB / NW vviiaa RRC signaling. The UECapabilitylnformation message may indicate that the UE supports the full power mode 2. The UECapabilitylnformation message may include the ul-FullPwrMode2-MaxSRS-ResInSet field, the ul-FullPwrMode2-SRSConfig-diffNumSRSPorts field, the ul-FullPwrMode2-TPMIGroup field, and / or the eight-tx-ul-FullPwrMode2-FullPwrGroup field within the FeatureSetUplink IE.

[0335] Moreover, the eight-tx-ul-FullPwrMode2-MaxSRS-ResInSet field may indicate that the (UE-supported) maximum number of SRS resources in one SRS resource set with usage set to “codebook” for eight TX uplink full power Mode 2 operation, the eight-tx-ul-FullPwrModeR-SRSConfig-diffNumSRSPorts field may indicate that the UE supports an SRS configuration with different number of antenna ports per SRS resource for the eight TX uplink full power mode 2 operation. In some implementations, the ul-FullP-wrMode2-TPMIGroup field may include the information associated with the four-port-UE-supported precoder(s) and / or the information associated with the two-port-UE-supported precoder(s) that deliver the full power. In some implementations, the eight-tx-ul-FullPwrMode2-FullP^rGroup field may include the information associated with one or more eight-port UE-supported antenna group combinations that deliver the full power.

[0336] In some implementations, in response to the UE receiving a UECapabilityEnquiry message from the gNB / NW via RRC signaling, the UE may transfer / transmit a UECapabilitylnformation message to the gNB / NW via RRC signaling. The UECapabilitylnformation message may indicate that the UE supports the full power mode 2. The UECapabilitylnformation message may include the ul-FullPwrMode2-MaxSRS-ReslnSet field, the ul-FullPwrMode2-SRSConfig-diffNumSRSPorts field, the ul-FullPwrMode2-TPMIGroup field, the eight-tx-ul-FullPwrMode2-PwrPerGroup field, and / or the eight-tx-ul-FullPwrMode2-FullPwrGroup field within the FeatureSetUplink IE.

[0337] The eight-tx-ul-FullPwrMode2-MaxSRS-Res!nSet field may indicate the (UE-supported) maximum number of SRS resources in an SRS resource set with usage set to ''codebook" for eight TX uplink full power Mode 2 operation. The eight-tx-ul-FullPwrMode2-SRSConfig-diffNumSRSPorts field may indicate that the UE supports an SRS configuration with different number of antenna ports per SRS resource for the eight TX uplink full power mode 2 operation. In some implementations, the ul-FullPwrMode2-TPMIGroup field may include the information associated with the full power precoder(s) supported by the four-port UE and / or the full power precoder(s) supported by the two-port UE. A full power precoder may refer to a precoder that delivers the full power. The eight-tx-ul~FullPwrMode2-FullPwrGroup field may indicate that the UE supports full power group(s) that delivers the full power, and / or may indicate the UE-supported full power group(s). The full power group(s) may represent antenna / TPMI group(s).

[0338] The eight-tx-ul-FullPwrMode2~PwrPerGroup field may include information associated with the maximum output power per antenna group / antenna port, where the information may be represented by a codepoint. For example, the information corresponding to one of four antenna groups for a UE supporting the Type E codebook subset may be set to a codepoint '007‘017‘117‘10,’ where each codepoint may represent an antenna group that can achieve a specific maximum output power (e.g., 17 dBm, 20 dBm, 23 dBm, Reserved), respectively. For example, one codepoint may represent an antenna group that can achieve a maximum output power of 17 dBm, another codepoint may represent an antenna group that can achieve a maximum output power of 20 dBm, and yet another codepoint may represent an antenna group that can achieve a maximum output power of 23 dBm. Additionally or alternatively, each of the codepoints (‘007‘017‘117‘ 10’) may represent a specific maximum output power (e.g., 17 dBm, 20 dBm, 23 dBm, or Reserved) that an antenna group can achieve. For example, one codepoint may represent a maximum output power of 17 dBm that an antenna group can achieve, another codepoint may represent a maximum output power of 20 dBm that an antenna group can achieve, and yet another codepoint may represent a maximum output power of 23 dBm that an antenna group can achieve.

[0339] In some implementations, if the UE reports to the gNB / NW that the Type E codebook subset is supported and that the full power mode 2 is supported, the UE may further report the information associated with the maximum output power per antenna group / antenna port. The information may be represented by a codepoint. In some implementations, the UE may report to the gNB / NW that the Type E codebook subset is supported and that the full power mode 2 is supported by reporting the information associated with the maximum output power per antenna group / antenna port.

[0340] In some implementations, in a case that the UE receives, from the BS / NW, the UECapabilityEnquiry message, the UE may transmit, to the BS / NW, the UECapabilitylnformation message in response to receiving the UECapabilityEnquiry message. The UECapabilitylnformation message may include the FeatureSetUplink IE. The FeatureSetUplink IE may include the supportedSRS-Resource field. The supportedSRS-Resource field may include the maxNumberSRS-Ports-P er Resource field. The maxNumberSRS-Ports-PerResource field may be used to indicate the supported maximum number of SRS ports per SRS resource, and the maxNumberSRS-Ports-PerResource field may be in an enumerated format (e.g., ENUMERATED {n1, n2, n4, n8}). With the enumerated format, the maxNumberSRS-Ports-PerResource field may indicate that the number of antenna ports for each SRS resource in the SRS resource set may be one, two, four, or eight. In some implementations, if the UE receives, from the BS / NW, an RRC message including the ul-FullPower Transmission field set to “fullpower 2” and is then indicated / configured with an SRS resource within an SRS resource set with usage set to “codebook,” the UE may perform the corresponding PUSCH transmission using the full power mode 2. The SRS resource set may include at least one 8-port SRS resource.

[0341] In some implementations, in a case that (i) the UE receives, from the BS / NW, the RRC signaling including the PUSCH configuration information (e.g., the PUSCH-Config IE) applicable to a particular (UL) BWP, and (ii) the PUSCH-Config IE includes the eight-tx-ul-FullPowerTransmission field indicating that the full power mode 2 is configured (e.g., the eight-tx-ul-FullPowerTransmission field is set to ''fiillpowerMode2 ”), the UE may perform the corresponding PUSCH transmission using the fall power mode 2. The eight-tx-ul-FullPowerTransmission field may be used to indicate that one of the full power mode, the full power mode 1, and the full power mode 2 is configured, and the eight-tx-ul-FullPowerTransmission field may be in an enumerated format (e.g., ENUMERATED {fullpower, fullpowerModel, fullpowerMode2}).

[0342] In some implementations, when the UE is configured, via the RRC signaling received from the BS / NW, with the full power mode 2 applicable to a particular (UL) BWP, the UE may further be configured, via the RRC signaling received from the BS / NW, with an SRS resource set with usage set to “codebook."” In some implementations, the SRS resource set may include one or more SRS resources, and each of the one or more SRS resources may have the same number of SRS ports. In some implementations, the SRS resource set may include one or more SRS resources, and each of the one or more SRS resources may have a different number of SRS ports.

[0343] In some implementations, when the UE is configured with the full power mode 2 and the codebook subset is set to Type D / E, the UE may be further configured, via the RRC signaling received from the BS / NW, with at least one 8-port SRS resource, a 4-port SRS resource, and / or a 2-port SRS resource in the configured SRS resource set with usage set to “codebook.” The RRC signaling may include a particular IE (e.g., the SRS-Config IE).

[0344] In some implementations, if (1) the UE reports to the gNB / N, via RRC signaling, that one or more TPMI groups can deliver the full power, and (2) the indicated / configured precoder used for the current CB PUSCH transmission is in one of the corresponding TPMI group(s), and (3) the UE is configured with the full power mode 2 operation, the UE may split the calculated PUSCH transmit power equally across the antenna ports on which the UE transmits the PUSCH with non-zero power, where a is equal to one.

[0345] In some implementations, if (1) the UE reports / reported / has reported to the gNB / NW that one or more antenna groups can deliver the full power, and (2) the UE is indicated / configured with a precoder used for the current CB PUSCH transmission from the corresponding antenna group(s), and (3) the UE is configured with the full power mode 2 operation, the UE may split the calculated PUSCH transmit power equally across the antenna ports on which the UE transmits the PUSCH with non-zero power, where a is equal to one. For example, if (1) the UE reports / reported / has reported to the gNB / NW that the Type E codebook subset is supported, and (2) the first antenna group and the second antenna group are able to deliver the full power, and (3) the UE is configured with the full power mode 2 operation by the gNB / NW, and (4) the UE is configured with the CB PUSCH transmission, and (5) the indicated / configured precoder(s) consist(s) of two 2-TX full-coherent precoders associated with the first antenna group and the second antenna group, respectively, the UE may perform the full power transmission in the full power mode 2 operation.

[0346] In some implementations, if (1) the UE reports / reported / has reported to the gNB / NW the maximum output power per antenna group, and (2) the indicated / configured precoder used for the current CB PUSCH transmission achieves, or is able to achieve, the full power transmission (e.g., based on the corresponding information), and (3) the UE is configured with the full power mode 2 operation, the UE may split the calculated PUSCH transmit power equally across the antenna ports on which the UE transmits the PUSCH with non-zero power, where α is equal to one. For example, if (1) the UE reports / reported / has reported to the gNB / NW that the Type E codebook subset is supported, and (2) the first antenna group is configured with the codepoint ’01,’ and the second antenna group is configured with the codepoint ’01,’ and (3) the full power is calculated as 23 dBm, and (4) the indicated / configured precoder consists of two 2-TX full-coherent precoders associated with the first antenna group and the second antenna group, respectively, the UE may perform the full power transmission in the full power mode 2 operation.

[0347] In some implementations, if (1) the UE reports / reported / has reported to the gNB / NW the maximum output power per antenna group / the supported full power antenna group(s) / the supported TPMI group(s), and (2) the indicated / configured precoder used for the current CB PUSCH transmission does not belong to the reported antenna group(s) / TPMI group(s), the UE may split the calculated PUSCH transmit power equally across the antenna ports on which the UE transmits the PUSCH with non-zero power, where α is equal to the ratio of the number of antenna ports with non-zero PUSCH transmission power to the number of SRS ports of the indicated SRS resource.

[0348] When the UE is configured, via the RRC signaling, the MAC CE, or the DCI received from the BS / NW, with the coherence capability to associate the UE, the combinations of layer splitting may be based on Table 2. Table 2 below illustrates combinations of layer splitting for two antenna groups, according to an example implementation of the present disclosure. [Table 2]

[0349] The first number in each pair may represent the number of transmission layers assigned to the first antenna group, while the second number in the pair may represent the number of transmission layers assigned to the second antenna group. Some combinations may be excluded if they do not provide significant benefits to the overall system performance.

[0350] When the UE is configured, via the RRC signaling, the MAC CE, or the DCI received from the BS / NW, with the coherence capability to associate the UE, the combinations of layer splitting may be based on Table 3. Table 3 below illustrates combinations of layer splitting for four antenna groups, according to an example implementation of the present disclosure.

[0351] [Table 3]

[0352] The first element in each 4-tuple may represent the number of transmission layers assigned to the first antenna group, the second element in each 4-tuple may represent the number of transmission layers assigned to the second antenna group, and the third element in each 4-tuple may represent the number of transmission layers assigned to the third antenna group, and the fourth element in each 4-tuple may represent the number of transmission layers assigned to the fourth antenna group. Some combinations may be excluded if they do not provide significant benefits to system performance.

[0353] FIG. 1 is a flowchart illustrating method / process 100 for full power transmissions, according to an example implementation of the present disclosure. Although actions 102 and 104 are illustrated, as separate actions, represented as independent blocks in FIG. 1, these separately illustrated actions should not be construed as to be necessarily order-dependent. The order in which the actions are performed in FIG. 1 is not intended to be construed as a limitation, and any number of the disclosed blocks may be combined in any order to implement the method, or an alternative method. Each of actions 102 and 104 may be performed independent of the other actions, and may be omitted in some implementations of the present disclosure. Moreover, method / process 100 may be combined with other procedures / methods described in the present disclosure. Process 100 may be performed by a UE (e.g., an 8-TX UE), with each action of process 100 corresponding to an operation executed by the UE.

[0354] In action 102, process 100 may start by receiving, from a BS, a UE capability enquiry message (e.g., an UECapabilityEnquiry message).

[0355] In action 104, process 100 may transmit, to the BS, a UE capability message (e.g., an UECapabilitylnformation message) in response to receiving the UE capability enquiry message. Process 100 may then end. The UE capability message may include UL feature set information (e.g., the FeatureSet Uplink IE) applicable to a dedicated UL BWP. The UL feature set information may include a first indicator, a second indicator, and a third indicator. The first indicator (e.g., the eight-tx-ul-FullPwrMode2-MaxSRS-Res!nSet field in the FeatureSetUplink IE) may indicate whether the 8-TX UE supports a full power mode 2 and may indicate a maximum number of SRS resources in an SRS resource set configured for a CB PUSCH transmission for the full power mode 2. The second indicator (e.g., the eight-tx-ul-FullPwrMode2-SRSConfig-diffNumSRSPorts field in the FeatureSetUplink IE) may indicate whether the 8-TX UE supports SRS configurations with different numbers of antenna ports per SRS resource for the full power mode 2. The third indicator (e.g., the eight-tx-ul-FullPwrMode2-FullPwrGroup field in the FeatureSetUplink IE) may indicate one or more full power groups capable of delivering full power in the CB PUSCH transmission per band or per band combination for the full power mode 2.

[0356] In some implementations, the third indicator may include a field (e.g., the eightPortsTypeE field) indicating one or more categories of antenna groups and one or more antenna group configurations for each category of the one or more categories of antenna groups.

[0357] In some implementations, the one or more categories of antenna groups may include a first category (e.g., Type I) where the full power transmissions are supported by one antenna group, a second category (e.g., Type II) where the full power transmissions are supported by two antenna groups, and a third category (e.g., Type III) where the full power transmissions are supported by three antenna groups.

[0358] In some implementations, the number of antenna ports for each SRS resource in the SRS resource set is one, two, four, or eight.

[0359] In some implementations, each full power group of the one or more full power groups may include an antenna group or a TPMI group.

[0360] Process 100 offers several technical advantages, particularly through the use of the first, second, and third indicators, which enhance the UE’s ability to communicate its capabilities regarding full power mode 2 operations. Specifically, the first indicator may provide the network with information about the maximum number of SRS resources the UE supports in a single SRS resource set for a CB PUSCH transmission, which may optimize the resource allocation for different SRS configurations. The second indicator may indicate whether the UE supports flexible SRS configurations with varying antenna port numbers, allowing the network to adjust settings based on the UE’s antenna capabilities. The third indicator may identify the full power group(s) supported by the UE, enabling the network to configure optimal power delivery across different antenna or TPMI groups. These indicators may allow the network to configure uplink transmissions efficiently, addressing challenges related to power usage and resource allocation in the full power mode 2.

[0361] It should be noted that the present disclosure describes the eight-tx-ul-FullPwrMode2-MaxSRS-ResInSet fifieelldd,. the eight-tx-ul-FullPwrMode2-SRSConfig-diffNumSRSPorts field, aanndd the eight-tx-ul-FullPwrMode2-FullPwrGroup field, along with implementations in which the UE reports these fields, all of which may be applied to and integrated with process 100.

[0362] It should also be noted that the BS may perform methods / actions corresponding to those performed by the UE. For example, the receiving actions performed by the UE may correspond to the transmitting / configuring actions of the BS; the transmitting actions performed by the UE may correspond to the receiving actions of the BS. That is, the BS and the UE may have reciprocally aligned roles in transmission and reception. For example, consider process 100 from the BS’s perspective: the BS may transmit, to the 8-TX UE, a UE capability enquiry message. The BS may further receive, from the 8-TX UE, a UE capability message after transmitting the UE capability enquiry message. The UE capability message may include UL feature set information (e.g., the FeatureSetUplink IE) applicable to a dedicated UL BWP. The UL feature set information may include a first indicator, a second indicator, and aa third indicator. The first indicator (e.g., the eight-tx-ul-FullPwrMode2-MaxSRS-ResInSet field in the FeatureSetUplink IE) may indicate whether the 8-TX UE supports a full power mode 2 and may indicate a maximum number of SRS resources in an SRS resource set configured for a CB PUSCH transmission for the full power mode 2. The second indicator (e.g., the eight-tx-ul-FullPwrMode2-SRSConfig-diffNumSRSPorts field in the FeatureSetUplink IE) may indicate whether the 8-TX UE supports SRS configurations with different numbers of antenna ports per SRS resource for the full power mode 2. The third indicator (e.g., the eight-tx-ul-FullPwrMode2-FullPwrGroup field in the FeatureSetUplink IE) may indicate one or more full power groups capable of delivering full power in the CB PUSCH transmission per band or per band combination for the full power mode 2.

[0363] FIG. 2 is a flowchart illustrating method / process 200 for mobility management, according to an example implementation of the present disclosure. Although actions 202, 204, and 206 are illustrated, as separate actions, represented as independent blocks in FIG. 2, these separately illustrated actions should not be construed as to be necessarily order-dependent. The order in which the actions are performed in FIG. 2 is not intended to be construed as a limitation, and any number of the disclosed blocks may be combined in any order to implement the method, or an alternative method. Each of actions 202, 204, and 206 may be performed independent of the other actions, and may be omitted in some implementations of the present disclosure. Process 200 may be seen as either a continuation of the earlier described methods / processes, including process 100, with additional detailed actions for mobility enhancement, or as a standalone approach offering a different or more detailed mechanism to enhance mobility. Moreover, process 200 may be integrated with process 100 and / or other methods / processes described in the present disclosure. Additionally, process 200 uses terminology that is consistent with or corresponds to the terminology utilized in process 100. Process 200 may be performed by a UE (e.g., an 8-TX UE).

[0364] In action 202, process 200 may start by receiving, from the BS, a CB PUSCH configuration.

[0365] In action 204, process 200 may receive, from the BS, a DCI format scheduling the CB PUSCH transmission.

[0366] In action 206, process 200 may perform, based on the CB PUSCH configuration and the DCI format, the CB PUSCH transmission using the full power mode 2.
