Uplink power control for improving the reliability of physical uplink channels

Abstract

The present application relates to devices and components, including apparatus, systems, and methods, for uplink power control for channels having repetition.

Description

[Background technology]

[0001] The 3rd Generation Partnership Project (3GPP) provides uplink power control to provide efficient uplink communications while limiting interference and power consumption in a user equipment (UE). To control uplink power, power control parameters may be provided to the UE. In 3GPP Release 15 and Release 16, the power control parameters are derived as follows: If a spatial relationship is configured, the power control parameters are set in the spatial relationship configuration. The spatial relationship is only applicable to frequency range 2 (FR2), i.e., 24,250 megahertz (MHz) to 52,600 MHz. If a spatial relationship is not configured, a default power control parameter may be selected from the first power control parameter in each power control parameter list configured by radio resource control (RRC) signaling.

[0025] 1 illustrates a network environment 100, according to some embodiments. The network environment 100 may include a UE 104 and one or more base station(s) 108. The base station 108 may provide one or more wireless serving cells, e.g., 3GPP New Radio (NR) cells, through which the UE 104 may communicate with the base station 108.

[0026] The UE 104 and base station(s) 108 may communicate over an air interface that conforms to 3GPP technical specifications, such as those defining the Fifth Generation (5G) NR system standard. The base station(s) 108 may include a Next Generation Radio Access Network (NG-RAN) node coupled to a 5G core network. The NG-RAN node may be either a gNB, which provides NR user plane and control plane protocol terminations toward the UE 104, or an ng-eNB, which provides Evolved Universal Terrestrial Radio Access (E-UTRA) user plane and control plane protocol terminations toward the UE 104.

[0027] The base station(s) 108 may be coupled with one or more distributed antenna panels (APs), e.g., AP 116 and AP 120. The distributed APs 116 / 120 may be implemented in transmit / receive points (TRPs) or other devices. In general, the base station(s) 108 may perform most of the operations of the communication protocol stack, including scheduling, while the APs 116 / 120 may function as distributed antennas. In some embodiments, the APs 116 / 120 may perform some lower-level operations of the communication protocol stack (e.g., analog physical (PHY) layer operations).

[0028] The base station(s) 108 may use the APs 116 / 120 to geographically separate multiple points from which signals can be transmitted to or received from the UE 104. This may increase the flexibility of using multiple-input, multiple-output, and beamforming enhancements to communicate with the UE 104. The APs 116 / 120 may be used to transmit downlink transmissions to the UE 104 and receive uplink transmissions from the UE 104. In some embodiments, the distributed transmit / receive capabilities provided by the APs 116 and 120 may be used for coordinated multipoint or carrier aggregation systems from one or more base stations.

[0029] Although the network environment 100 depicts a base station(s) 108 communicating with the UE 104 through the APs 116 / 120, in various embodiments, the network environment 100 may include several other network elements (e.g., base stations, TRPs, eNBs, etc.) that facilitate wireless access network connectivity for the UE 104.

[0030] The base station(s) 108 may transmit information (e.g., data and control signaling) in the downlink direction by mapping logical channels onto transport channels and mapping transport channels onto physical channels. Logical channels may transfer data between the Radio Link Control (RLC) layer and the Medium Access Control (MAC) layer. Transport channels may transfer data between the MAC layer and the PHY layer, and physical channels may transfer information over the air interface.

[0031] The AP 116 and one or more antenna panels on the UE 104 may include arrays of antenna elements that enable receive or transmit beamforming. Beamforming can improve uplink and downlink budgets by determining and using uplink and downlink beams that increase antenna gain and overall system performance. The UE 104 and base station 108 may determine desired uplink-downlink beam pairs using beam management operations based on reference signal measurements and channel symmetry assumptions.

[0032] In the downlink direction, the base station 108 may transmit synchronization signal blocks (SSBs) and channel state information reference signals (CSI-RSs), which are measured by the UE 104 to determine a desired downlink beam pair for transmitting / receiving physical downlink control channel (PDCCH) and physical downlink shared channel (PDSCH) transmissions. In some embodiments, the network element may assume uplink / downlink beam coincidence and use the desired downlink beam pair as the desired uplink beam pair for physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) transmissions. In some embodiments, the beam pair may be determined independently for the uplink direction based on a sounding reference signal (SRS) transmitted by the UE 104. In various embodiments, beam management may include different stages, such as initial acquisition of uplink and downlink beams and subsequent refinement of the uplink and downlink beams.

[0033] To improve the reliability and coverage of a PUCCH transmission, the UE 104 may transmit multiple repetitions of the PUCCH transmission. The repetitions may be transmitted in the same slot or in different slots. As used herein, each PUCCH transmission containing the same information may be referred to as a repetition, even if the PUCCH transmission is the original or initial PUCCH transmission.

[0034] The base station(s) 108 may control the uplink transmit power of the uplink channels by providing power control configuration information to the UE 104 using any combination of RRC signaling, MAC control element (CE) signaling, and downlink control information (DCI). The power control configuration information may set power control parameters such as, but not limited to, P0 (uplink power value in dBm), alpha (possible values ​​of path loss compensation factor for uplink power control), path loss reference signal (RS), and closed-loop index. The base station(s) 108 may separately control uplink power control parameters for different uplink channels, including, for example, the PUSCH, PUCCH, physical random access channel (PRACH), and sounding reference signal (SRS).

[0035] Power control for the PUSCH may be performed in an open-loop or closed-loop manner and may be similar to that described in Section 7.1 of 3GPP Technical Specification (TS) 38.213 v16.3.0 (2020-09) except as otherwise described herein. Power control for the PUCCH may be performed using a closed-loop manner and may be similar to that described in Section 7.2 of 3GPP TS 38.213 except as otherwise described herein. The closed-loop power control process may be based on feedback received from the base station(s) 108 in the form of transmit power control (TPC) commands. The TPC commands may be transmitted to the UE 104 through DCI on the PDCCH.

[0036] In some embodiments, the base station(s) 108 may transmit TPC commands using DCI format 2_2. The DCI payload may signal the adjustment state to which the TPC command should be applied. As described in section 7.2.1 of 3GPP TS 38.213, the closed-loop power control process for the PUCCH then calculates the TPC command accumulation g b,f,c It may work by determining (i,l) as follows:

number

[0037] In some embodiments, the base station v 108 may send a PUCCH Power Control information element (IE) to the UE 104 to configure UE-specific parameters for power control of the PUCCH. The PUCCH-PowerControl IE may be as follows:

number

[0038] The fields of the PUCCH-PowerControl IE may be similar to those described in 3GPP TS 38.331 v16.2.0(2020-09). The P0-PUCCH-Value field may contain the uplink transmit power value (P0) for the PUCCH with a step size of 1 decibel (dB). The deltaF-PUCCH-f0 field may contain the UE transmit power offset (deltaF) value for PUCCH format 0 (and other deltaF fields may similarly contain deltaF values ​​for the corresponding PUCCH formats). The p0-Set field may contain a set (e.g., P01, P02, ...) with dedicated P0 values ​​for the PUCCH. The pathlossReferenceRSs provides a set of reference signals (e.g., channel state information reference signals (CSI-RS) or synchronization signal blocks (SSBs)) from which the UE 104 should measure path loss estimates for PUCCH power control.

[0039] If the UE 104 is not configured with a spatial relationship setting (e.g., the PUCCH-SpatialRelationInfo IE shown below), the UE 104 may select the first instance of P0-PUCCH, e.g., the instance with identification "0".

[0040] As mentioned above, the spatial relationship may be configured within FR2. The spatial relationship configuration and PUCCH power control parameters for a given PUCCH transmission may be configured by the base station(s) 108 sending a PUCCH-SpatialRelationInfo IE to the UE 104. The PUCCH-SpatialRelationInfo IE may be as follows:

number

[0041] The fields of the PUCCH-SpatialRelationInfo IE may be similar to those described in 3GPP TS 38.331. The pucch-PathlossReferenceRS-ID and p0-PUCCH Id may point to specific instances of the PUCCH-PathlossReferenceRS and P0-PUCCH defined in the PUCCH-PowerControl IE. The closedLoopIndex may identify the closed loop power control process.

[0042] The base station(s) 108 may configure a list of spatial relationships using the PUCCH-SpatialRelationInfo IE for each PUCCH resource. The base station(s) 108 may then select one or two of the configured spatial relationships using the MAC CE. To support PUCCH reliability extensions for FR2, two spatial relationships may be considered in Release 17. This may allow the UE 104 to apply different beams for transmitting different PUCCH repetitions on the same TRP or different TRPs.

[0043] The current state of the art has several challenges with regard to efficiently controlling uplink transmit power control for PUCCH transmissions with multiple repetitions that may be carried by more than one beam and transmitted to more than one TRP. Generally, at least three problems are not adequately addressed in the current state of the art:

[0044] For the first problem, since the spatial relationship is not applicable to FR1, it may be necessary to define support for different power control parameters for different PUCCH repetitions.

[0045] Second, if beam hopping is provided to support intra-slot multi-beam operation, different beams may be applied to different hops for PUCCH transmission within the same slot. Therefore, it may be necessary to define how to perform uplink power control in this scenario for communication in both FR1 and FR2.

[0046] A third issue may relate to updating the closed-loop power control coefficients based on the TPC commands indicated by the DCI. For PUCCH / PUSCH reliability improvement through iterations, it may be necessary to address how to apply the TPC commands at each iteration for communication in both FR1 and FR2.

[0047] For example, to provide PUCCH power control enhancement for FR1 as described in the first problem, the following options are provided:

[0048] In the first option, Option 1, different default power control parameters may be applied to different PUCCH repetitions. As mentioned above, different PUCCH repetitions may be transmitted in different TRPs. Therefore, it may be advantageous to provide the system with the flexibility to control the uplink transmission power separately for these different PUCCH repetitions. Option 1 may include at least two sub-options that may be used independently or in conjunction with each other.

[0049] In the first sub-option, Option 1-1, first parameters of a set may be applied to a first beam, while second parameters of the set may be applied to a second beam. For example, the P0-set configured by the PUCCH-PowerControl IE may include multiple P0s including a first P0 and a second P0, and multiple pathlossReferenceRSs including a first path loss RS and a second path loss RS. In Option 1-1, the first P0 in the P0-set may be applied to the first beam, and the second P0 in the P0-set may be applied to the second beam. Similarly, the first path loss RS of the multiple pathlossReferenceRSs may be applied to the first beam, and the second path loss RS of the multiple pathlossReferenceRSs may be applied to the second beam.

[0050] In the second sub-option, Option 1-2, the base station(s) may configure additional sets of parameters, with the first parameter of each set applying to each beam. For example, the PUCCH-Power-Control IE may configure multiple P0 sets and multiple pathlossReferenceRS sets. The first P0 in the first P0 set may apply to a first beam, while the first P0 in the second P0 set may apply to a second beam.

[0051] In some embodiments, when two closed-loop power control processes are enabled for the PUCCH, different closed-loop power control process indices may be applied to different iterations. This provides the base station(s) 108 with flexibility as to whether different loops are desired for different PUCCH iterations. In some cases, when multiple power control parameter sets apply to a PUCCH iteration, the base station(s) 108 may enable two closed-loop power control processes (e.g., enable two adjustment states). For example, with respect to Equation 1, which is the closed-loop power control equation, the value of l may be different for the two power control parameter sets. Thus, different g will be applied to different iterations corresponding to each PUCCH parameter set.

[0052] In other embodiments, the first closed-loop power control process may be applied regardless of whether a closed-loop power control process is enabled for the PUCCH, for example, the first closed-loop power control process may be applied to all PUCCH repetitions even if more than one closed-loop power control process is enabled.

[0053] In some embodiments, option 1-2 may be enabled by updating the PUCCH-PowerControl IE as follows:

number

[0054] As can be seen with reference to the previous PUCCH-PowerControl IE, this PUCCH-PowerControl IE is updated to configure additional sets, such as P0-Set1 and pathlossReferenceRSs1. Thus, the first P0 from P0-Set can be applied to the PUCCH repetition of the first beam, and the first P0 from P0-Set1 can be applied to the PUCCH repetition of the second beam. Similarly, the pathloss RS from pathlossReferenceRS can be applied to the PUCCH repetition of the first beam, and the pathloss RS from pathlossReferenceRS can be applied to the PUCCH repetition of the second beam. In other embodiments, additional / alternative power control (PC) parameter sets may be provided.

[0055] In some embodiments, the base station(s) 108 may configure the UE 104 with a mapping between PC parameter sets (e.g., including P0, path loss RS, and closed-loop index) and PUCCH repetitions. The mapping may be configured by RRC signaling, MAC CE, or DCI. In some embodiments, the mapping may be predefined, for example, in a 3GPP TS.

[0056] 2 illustrates two mapping schemes that may be used to map two parameter sets to four PUCCH repetitions, according to some embodiments. Specifically, cyclic mapping 204 indicates that the parameter sets rotate for successive PUCCH repetitions. For example, PC parameter set 1 is applied to repetition 1, PC parameter set 2 is applied to the next PUCCH repetition, repetition 2, PC parameter set 1 is applied to the next PUCCH repetition, repetition 3, and PC parameter set 2 is applied to the last PUCCH repetition of the set.

[0057] In sequential mapping 208, separate parameter sets may be mapped to successive PUCCH repetitions. For example, PC parameter set 1 may be mapped to PUCCH repetitions 1 and 2, and then PC parameter set 2 may be mapped to PUCCH repetitions 3 and 4.

[0058] In various embodiments, other numbers of PUCCH repetitions and PC parameter sets may be used by applying similar concepts.

[0059] In a second option, Option 2, power control parameters for PUCCH resources (e.g., in FR1) that do not have a PUCCH-SpatialRelation IE may be configured by higher layer signaling. For example, base station(s) 108 may send configuration information via RRC signaling or MAC CE to configure the PUCCH power control parameters. Option 2 may include at least two sub-options that can be used independently or in conjunction with each other.

[0060] In the first sub-option, option 2-1, one or two sets of power control parameters for PUCCH resources may be configured by RRC. For example, base station(s) may generate a PUCCH resource IE to configure resources with one or more sets of power control parameters. A PUCCH resource IE with one set of power control parameters is shown as follows:

number

[0061] The PUCCH-Resource IE may be a component of the PUCCH-Config IE. The fields of the PUCCH-Resource IE may be similar to those described in 3GPP TS 38.331. However, according to this embodiment, the PUCCH-Resource IE may also include a PUCCH path loss RS ID, a P0-PUCCH ID, and a PC parameter set with a closed-loop index, as shown.

[0062] The PUCCH resource IE with two sets of power control parameters is shown below:

number

[0063] This PUCCH resource IE may be similar to that shown and described above, except that this PUCCH resource IE may also include PUCCH path loss RS ID1, P0-PUCCH ID1, and a second PC parameter set having closed-loop index 1.

[0064] In this way, the PUCCH resource may be used to configure one or two sets of power control parameters outside of the PUCCH spatial relationship, which may provide more flexibility to the base station(s) 108 to select different power control parameters for different PUCCH resources.

[0065] In a second sub-option, sub-option 2-2, some or all of the power control parameters for a PUCCH resource or group of PUCCH resources may be configured by the MAC CE.

[0066] In some embodiments, sub-option 2-1 may be used to provide power control parameters before the MAC CE is received as additional configuration, which may update the originally configured power control parameters or select one of multiple PC parameter sets to use for a particular resource.

[0067] In some embodiments, the MAC CE may update power control parameters for PUCCH resources in one or more serving cells. In some embodiments, the power control parameters may be updated for the serving cell transmitting the MAC CE or another serving cell. In embodiments in which the MAC CE updates power control parameters for PUCCH resources in multiple serving cells, the MAC CE may do so by using a serving cell list that resides in the MAC CE itself or that was previously configured by RRC signaling.

[0068] In either sub-option 2-1 or sub-option 2-2, one or two sets of power control parameters may be applied to the PUCCH resources.

[0069] If a set of power control parameters is applied to a particular PUCCH resource, the base station(s) 108 may Uplink control information ( UCI ) , N PUCCH resources (where N>1, e.g., N=2) may be triggered to report the target TRP. Each of the N PUCCH resources may then be associated with its own set of power control parameters. In this way, different PUCCH resources carrying different PUCCH repetitions may have power control parameters appropriate for the intended target TRP.

[0070] When two sets of power control parameters apply to a particular PUCCH resource, the mapping of PC parameter sets to PUCCH repetitions may be predefined or configured using RRC signaling, MAC CE, or DCI by base station(s) 108. For example, PC parameter sets may be mapped to PUCCH repetitions using cyclic or sequential mapping, similar to that described above with respect to FIG.

[0071] In a third option, Option 3, M PC parameter sets for PUCCH resources without PUCCH-SpatialRelation may be configured by higher layer signaling, e.g., RRC signaling, or MAC CE, where M >= 2. DCI may then be used to select one or two sets from the M PC parameter sets for PUCCH transmission.

[0072] 3 illustrates two scenarios for signaling PC parameter sets, according to some embodiments. In scenario 304, the PC parameter set(s) may be provided by a combination of RRC, MAC CE, and DCI signaling. For example, base station(s) 108 may configure UE 104 with PC parameter sets (0-7) using RRC signaling (e.g., M=8). After some time, base station(s) 108 may send a MAC CE to UE 104 to activate multiple PC parameter sets. One or more activated PC parameter sets may correspond to each of multiple DCI code points. As shown, the PC parameter sets 0 and 1may correspond to the first DCI codepoint (e.g., codepoint=0). PC parameter set 0 may correspond to the second DCI codepoint (e.g., codepoint=1). PC parameter sets 3 and 4 may correspond to the third DCI codepoint (e.g., codepoint=2). PC parameter sets 1 and 2 may correspond to the fourth DCI codepoint (e.g., codepoint=3). At some later time, the base station(s) 108 may transmit a DCI with a DCI codepoint value corresponding to the PC parameter set to apply to the subsequent uplink transmission. As shown, DCI codepoint=2 may be transmitted to select PC parameter sets 3 and 4.

[0073] In scenario 308, the PC parameter set(s) may be provided by RRC and MAC CE signaling. For example, base station(s) 108 may configure UE 104 with multiple PC parameter sets using RRC signaling similar to that described above. However, instead of base station(s) 108 using MAC CE to activate PC parameter sets corresponding to multiple code points as described above, the MAC CE may activate only one or two PC parameter sets corresponding to one code point. Thus, in this embodiment, DCI signaling is not required to indicate the PC parameter sets to apply to subsequent transmissions.

[0074] If more than one PC parameter set is selected for application, the mapping of parameter sets to PUCCH repetitions may be similar to that described above. For example, the mapping may be predefined or provided by configuration signaling. The mapping may include cyclic or sequential mapping.

[0075] 4 shows a signaling diagram 400 illustrating PUCCH reliability enhancement using intra-slot beam hopping, according to some embodiments. The signaling diagram 400 includes a first PUCCH repetition 404 transmitted using beam 1 as the first hop for PUCCH resource 1 and a second PUCCH repetition 408 transmitted using beam 2 as the second hop for PUCCH resource 1. The first hop and second hop may be transmitted within the same slot on the same or different TRPs.

[0076] Power control may be applied differently to hops carrying PUCCH repetitions 404 and 408 based on whether a spatial relationship setting is provided for the PUCCH resource.

[0077] In a first option for embodiments in which spatial relationship settings are provided for PUCCH resources, different power control parameters corresponding to different PUCCH spatial relationship settings may be applied to each hop. For example, power control parameters from a first spatial relationship setting may be applied to PUCCH repetition 404 (hop 1), and power control parameters from a second spatial relationship setting may be applied to PUCCH repetition 408 (hop 2). Power control may be performed for every N symbols within one transmission opportunity (e.g., per hop).

[0078] In some embodiments, gaps may be provided between hops to facilitate uplink power adjustment at the UE 104. The gaps may be based on power conversion delays associated with the UE 104, either specifically or generally. In some embodiments, the gaps may be predefined or set by the base station(s) 108, or may be reported by the UE 104. For example, the UE 104 may report its capabilities, and the base station(s) 108 may set the gaps accordingly.

[0079] In a second option for an embodiment in which spatial relationship settings are provided for PUCCH resources, power control parameters corresponding to one of the PUCCH spatial relationship settings may be applied to both hops. In this embodiment, both PUCCH repetitions 404 and 408 may be transmitted at the same power on the same TRP, even if they are transmitted by different beams. Power control may still be performed per transmission opportunity (e.g., per hop). The PUCCH spatial relationship setting to apply to a hop may be predefined. For example, the PUCCH spatial relationship setting with the lowest or highest ID may be applied. In other embodiments, the PUCCH spatial relationship setting to apply to a hop may be configured by the base station(s) 108 using RRC signaling or MAC CE.

[0080] In a third option, for embodiments where spatial relationship configuration is provided for PUCCH resources, a common set of power control parameters may be applied to both hops. The common set of power control parameters, which may be configured by RRC, MAC CE, or DCI, may override any PC parameters in the spatial relationship.

[0081] In a first option, for embodiments where no spatial relationship settings are provided for PUCCH resources (e.g., within FR1), a different set of power control parameters may be applied to each hop. In some embodiments, the different sets of power control parameters are ,above The PC parameter sets may be configured for the PUCCH resources in a manner similar to that described above: a first set of PC parameter sets may be applied to a first hop with PUCCH repetitions 404, and a second set of PC parameter sets may be applied to a second hop with PUCCH repetitions 408.

[0082] If more than one hop is supported, the mapping of PC parameter sets to hops may be similar to that described above for the mapping of PC parameter sets to repetitions. For example, the hop-to-set mapping may be predefined or configured by RRC signaling, MAC CE, or DCI. In some embodiments, the hop-to-set mapping may be based on a cyclic or sequential mapping similar to that shown and described with respect to FIG. 2.

[0083] Power control may be performed on a hop-by-hop basis. In some embodiments, gaps may be predefined or set by the base station(s) 108 to accommodate power conversion delays of the UE 104. In some embodiments, gaps may be based on UE reports requesting or indicating a desired gap size to accommodate power conversion.

[0084] In a second option, for embodiments where no spatial relationship configuration is provided for PUCCH resources, a common set of power control parameters may be applied to multiple hops, including, for example, a first hop with PUCCH repetition 404 and a second hop with PUCCH repetition 408. The common set of power control parameters may be configured by RRC signaling, MAC CE, or DCI.

[0085] To address the third problem mentioned above, the TPC commands in the DCI may be applied for the PUCCH in repetitions with corresponding power control processes, where the PUCCH repetitions may be based on the same or different closed-loop PC processes.

[0086] If the PUCCH repetitions are based on the same closed-loop PC process, the TPC command may be applied to all PUCCH repetitions for that configured closed-loop PC process. In some embodiments, as a further enhancement, a common closed-loop PC process may be applied to the PUCCH resources with repetitions.

[0087] If PUCCH repetitions correspond to different closed-loop PC processes, one of at least four options may be used: To illustrate these options, consider an example in which PUCCH repetition 1 is associated with a PC parameter set having a first closed-loop index, and PUCCH repetition 2 is associated with a PC parameter set having a second closed-loop index.

[0088] In a first option, the TPC command may be applied to one of the closed-loop PC processes. The closed-loop PC process to which the TPC command may be applied may be predefined or configured by RRC signaling, MAC CE, or DCI. Thus, if the received TPC command is associated with a closed-loop PC process having a second closed-loop index, the UE 104 may apply the power control factor indicated by the TPC command to PUCCH repetition 2.

[0089] In a second option, the TPC commands may be applied to both closed-loop PC processes using the same indicated value, so the UE 104 may apply the power control factor indicated by the TPC commands to both PUCCH repetitions 1 and 2.

[0090] In a third option, the indication of the TPC command may be set by higher layer signaling, such as RRC signaling or MAC CE. In one example, one MAC CE can set the closed-loop PC process(es) to be applied or the value of the closed-loop PC coefficients for each TPC command. For example, in the case of a 2-bit TPC command, the MAC CE can select one of four states, e.g., {0 dB, 0 dB}, {1 dB, 3 dB}, {3 dB, 3 dB}, and {-1 dB}. ,0 dB}. The first value of the value pair may be set to correspond to the first closed-loop PC process, and the second value of the value pair may correspond to the second closed-loop PC process. These four states set by the MAC CE may correspond to TPC commands 0, 1, 2, and 3. If the base station(s) 108 send a TPC command of "1," the UE 104 may apply a 1 dB adjustment to the first PUCCH repetition associated with the first closed-loop PC process and a 3 dB adjustment to the second PUCCH repetition associated with the second closed-loop PC process.

[0091] In some embodiments, the MAC CE may support inter-serving cell configuration, for example, a MAC CE may be received in a first serving cell to configure TPC commands in a second serving cell.

[0092] In a fourth option, the TPC command indications may be predefined. For example, in some embodiments, the TPC command indications may be predefined as shown in Table 1. [Table 1]

[0093] In this way, the base station(s) may send a TPC command value of, for example, 2 to instruct the UE to apply a 1 dB adjustment to PUCCH repetition 1 and a 0 dB adjustment to PUCCH repetition 2.

[0094] In some embodiments, for example, the TPC command indications predefined by Table 1 may be default values, which may be overridden by subsequent MAC CE configurations such as those described above with respect to the third option.

[0095] In other embodiments, additional bits may be added for the TPC commands for the fourth option, and an RRC parameter may be introduced to allow the DCI format to accommodate such TPC commands.

[0096] 5 illustrates an operational flow / algorithm structure 500 according to some embodiments. The operational flow / algorithm structure 500 may be executed or implemented by a UE, such as UE 104 or UE 900, or a component of that UE, such as baseband processor 904A.

[0097] The operational flow / algorithm structure 500 may include receiving PC configuration information for FR1 communication at 504. In some embodiments, the PC configuration information may be received in one or more PUCCH resource configurations, e.g., a PUCCH-Resource IE, or one or more PUCCH power control configurations, e.g., a PUCCH-PowerControl. In various embodiments, the PC configuration information may be received via one or more control signaling layers. For example, the PC configuration information may be transmitted by RRC signaling, MAC CE, or DCI. As described elsewhere herein, some embodiments include transmitting the PC configuration information using a combination of different control signals. For example, RRC signaling may be used to initially configure the PC parameters, while MAC CE or DCI may be used to update the PC parameters or to provide more detailed instructions regarding which of the configured PC parameters to use for uplink transmissions.

[0098] The PC configuration information may be configured for one PUCCH resource or for a group of PUCCH resources, and the PUCCH resource(s) may be in the same serving cell in which the PC configuration information is transmitted or in different serving cells.

[0099] The PC configuration information may configure multiple PC parameters, including, for example, P0, a path loss RS, and a closed-loop index. These parameters may be configured in one or more sets or subsets. For example, in one embodiment, the PC parameters may include a P0 set and multiple path loss RSs. In another embodiment, multiple PC parameter sets may be configured, with each PC parameter set including a P0 set and a list of path loss RSs.

[0100] The operational flow / algorithm structure 500 may further include selecting, at 508, a first PC parameter to use for a first repetition of the PUCCH transmission and selecting, at 512, a second PC parameter to use for a second repetition of the PUCCH transmission. Determining which PC parameters to apply to different repetitions may be accomplished as described with respect to any of the embodiments described herein. For example, a first P0 of the P0 set may be applied to the first repetition, a second P0 of the P0 set may be applied to the second repetition, a first P0 of the P0 set of the first PC parameter list may be applied to the first repetition, a first P0 of the P0 set of the second PC parameter list may be applied to the second repetition, etc. The path loss RS to apply to different repetitions may also be selected in a manner similar to the P0 values.

[0101] In some embodiments, when more than one PC parameter set is configured, each PC parameter set may be mapped to each repetition using a cyclic or sequential mapping pattern. In some embodiments, the mapping of PC parameter sets to PUCCH repetitions may be predefined or based on gNB signaling (e.g., RRC signaling, MAC CE, or DCI).

[0102] The operational flow / algorithm structure 500 may further include transmitting a first iteration applying a first PC parameter to a first beam and a second iteration applying a second PC parameter to a second beam at 516. In some embodiments, the first iteration may be transmitted to a first TRP using the first beam, and the second iteration may be transmitted to a second TRP using the second beam. Providing flexibility to adapt the power control parameters applied to each of these iterations can increase both the reliability and efficiency of transmissions.

[0103] 6 illustrates an operational flow / algorithm structure 600 according to some embodiments. The operational flow / algorithm structure 600 may be executed or implemented by a UE, such as, for example, the UE 104 or the UE 900, or a component thereof, for example, the baseband processor 904A.

[0104] The operational flow / algorithm structure 600 may include encoding UCI to be transmitted in one slot over multiple hops for a PUCCH resource at 604. In some embodiments, a time gap may be provided between successive hops to accommodate power conversion that may be performed by the UE, for example, if the uplink transmit power is different for different hops. This gap may be predefined or configured by the gNB.

[0105] The same UCI may be transmitted in each of multiple hops in a slot. This intra-slot beam hopping may improve the reliability of the UCI carried in the PUCCH resource.

[0106] In some embodiments, spatial relationship setting information may be provided. This setting information may be provided, for example, if the PUCCH resource is within FR2. One or more spatial relationship settings may provide one or more PC parameters.

[0107] In other embodiments, spatial relationship setting information may not be provided, which may be the case when the PUCCH resource is within FR1. In various embodiments, one or more power control parameters may be configured for each PUCCH resource.

[0108] In some embodiments, a common set of power control parameters may be configured regardless of whether spatial relationship configuration information is provided.

[0109] The operational flow / algorithm structure 600 may further include transmitting the first hop using the first PC parameters, at 608, and transmitting the second hop using the first or second PC parameters, at 612. If a common set of power control parameters is provided, the first PC parameters may be considered the common set and may apply to both the first and second hops.

[0110] In some embodiments, the PC parameters may be received in first and second spatial relationship settings provided for the PUCCH resources. The UE may apply the PC parameter provided by one of the spatial relationship settings (the "first power control parameter" described at 608 and 612) to both the first and second hops, or may apply the first PC parameter provided by the first spatial relationship setting to the first hop and the second PC parameter provided by the second spatial relationship setting to the second hop.

[0111] In embodiments where spatial relationships are not configured, the UE may be configured with multiple sets of PC parameters for PUCCH resources with repetition, in some embodiments, the first PC parameter may be from the first set of PC parameters and the second PC parameter may be from the second set of PC parameters.

The operational flow / algorithm structure 700 may be implemented, for example, by a base station(s) 108 Alternatively, it may be performed or implemented by a base station such as the gNB 1000, or a component thereof, such as the baseband processor 1004A.

[0113] The operational flow / algorithm structure 700 may include generating 704 one or more DCIs to schedule PUCCH repetitions and to provide TPC commands. In some embodiments, one DCI may both schedule PUCCH repetitions and provide TPC commands. In other embodiments, a first DCI may schedule PUCCH repetitions and a second DCI may provide TPC commands.

[0114] A PUCCH repetition may be associated with one or more closed-loop PC processes. A TPC command may be an instruction to adjust uplink power associated with the closed-loop PC process. If multiple repetitions are associated with one closed-loop PC process, the TPC command may apply to all of the repetitions. If each repetition is associated with a closed-loop PC process, the TPC command may provide a coefficient to be applied to one of the multiple processes / iterations, a coefficient to be applied to all (or a subset) of the processes, or multiple coefficients to be applied to each of the multiple processes / iterations. In some embodiments, to provide multiple coefficients to be applied to each of the multiple processes / iterations, the TPC command may be a one-bit or two-bit command that references a configured codepoint corresponding to a pair of values ​​of closed-loop power control coefficients. The correspondence may be predefined, for example, by 3GPP TS or configured by RRC or MAC CE.

[0115] The operational flow / algorithm structure 700 may further include transmitting one or more DCIs to the UE, at 708. The DCIs may be transmitted from one or more TRPs within one PDCCH.

[0116] The operational flow / algorithm structure 700 may further include receiving at least one PUCCH repetition, at 712. The PUCCH repetition may be transmitted from the UE at an uplink transmit power based on the TPC command. In some embodiments, multiple PUCCH repetitions may be received by one or more TRPs. These repetitions may be transmitted to different TRPs using different beams.
