Description

Methods, devices, and communication systems for sending and receiving power margin reports Technical Field

[0001] This application relates to the field of communication technology. Background Technology

[0002] A Power Headroom Report (PHR) is a process by which a terminal device reports its uplink power headroom to network equipment (such as a base station). The main purpose of a PHR is to provide network equipment with information about the uplink power usage of the terminal device, enabling effective resource scheduling and power control. Power headroom, for example, refers to the difference between the terminal device's maximum transmit power and its uplink transmission power.

[0003] Power headroom reports can be triggered in the following ways:

[0004] Periodic triggering: Triggered and periodically reported via a timer (such as phr-PeriodicTimer) configured by RRC (Radio Resource Control).

[0005] Event triggering: When the path loss (path loss) changes beyond the configured threshold (such as phr-Tx-PowerFactorChange), when the PHR function is configured or reconfigured, or when the secondary cell (SCell) is activated, the terminal device will trigger a power margin report.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0007] For different time-domain resources, the power control parameters that should be used may differ due to differences in antenna configuration and channel conditions (such as interference).

[0008] For example, in traditional technologies, uplink transmission can only occur during uplink time slots in Time Division Duplex (TDD) bands. When limited or few uplink time slots are allocated, problems arise such as small uplink coverage, limited capacity, and high latency. To improve uplink capacity and coverage, and reduce uplink latency, network devices in TDD bands can operate in full-duplex mode at certain time points. For instance, at these time points, the network device simultaneously receives and transmits on different frequency domain resources within the corresponding carrier of the TDD band. This operating mode is, for example, called Subband Non-overlapping Full Duplex (SBFD), but is not limited to this. Under this operating mode, the power control parameters used for different time domain resources may differ.

[0009] For example, in order to improve network capacity, multiple antennas may be deployed in the same cell, and different antennas transmit in a time-division manner. Under this working mode, the power control parameters that should be used for different time domain resources may be different.

[0010] However, there is currently no solution for configuring power control parameters for different time-domain resources and supporting power margin reporting when different power control parameters are required for different time-domain resources.

[0011] To address at least one of the above-mentioned problems, embodiments of this application provide a method, apparatus, and communication system for transmitting and receiving power margin reports.

[0012] According to one aspect of the embodiments of this application, a method for transmitting a power margin report is provided, including:

The uplink power control information element can include two sets of power control parameters for PUSCH. The two sets of power control parameters include a first power control parameter set and a second power control parameter set. Each power control parameter set includes a target power and / or a path loss compensation factor and / or a closed-loop index.

[0014] The terminal device sends one or two power margins for the cell, wherein the one or two power margins include: a first power margin associated with the first power control parameter set, and / or a second power margin associated with the second power control parameter set.

Each power control parameter set includes a target power and / or a path loss compensation factor and / or a closed-loop index.

[0020] The network device receives one or two power margins from the cell, wherein the one or two power margins include: a first power margin associated with the first power control parameter set, and / or a second power margin associated with the second power control parameter set.

[0023] A receiver that receives one or two power margins of the cell, wherein the one or two power margins include: a first power margin associated with the first power control parameter set, and / or a second power margin associated with the second power control parameter set.

For example, the power control parameter sets for PUSCH, PUCCH, and SRS are provided by different (higher-layer) parameters in the uplink power control information element. As another example, the power control parameter sets for at least two of PUSCH, PUCCH, and SRS are provided by the same (higher-layer) parameters in the uplink power control information element.

[0086] In some embodiments, for a specific cell, the first power control parameter set, the third power control parameter set, and the fifth power control parameter set are mandatory in the uplink power control information element, or the first power control parameter set, the third power control parameter set, and the fifth power control parameter set are optional in the uplink power control information element.

[0087] In some embodiments, for a specific cell, the second power control parameter set / fourth power control parameter set / sixth power control parameter set is mandatory in the uplink power control information element, or the second power control parameter set / fourth power control parameter set / sixth power control parameter set is optional in the uplink power control information element.

[0088] In some embodiments, for cells other than the specific cell, the first power control parameter set / the third power control parameter set / the fifth power control parameter set may be present in the uplink power control information element, and / or the second power control parameter set / the fourth power control parameter set / the sixth power control parameter set may not be present in the uplink power control information element.

[0089] In some embodiments, (for the specific cell) there are constraints on the sets of power control parameters present in different uplink power control information elements. For example, each uplink power control information element may (must) contain or may not contain the first power control parameter set / third power control parameter set / fifth power control parameter set and / or the second power control parameter set / fourth power control parameter set / sixth power control parameter set, and / or, the number of power control parameter set parameters (for PUSCH / PUCCH / SRS) present in each uplink power control information element is the same.

[0090] For example, only two configurations are allowed: either all uplink power control information elements contain the second power control parameter set / fourth power control parameter set / sixth power control parameter set, or none of them contain the second power control parameter set / fourth power control parameter set / sixth power control parameter set. The following configurations are not allowed: some uplink power control information elements contain the second power control parameter set / fourth power control parameter set / sixth power control parameter set, or another part of the uplink power control information elements does not contain the second power control parameter set / fourth power control parameter set / sixth power control parameter set.

[0091] For example, only two configurations are allowed: either each uplink power control information element contains two sets of power control parameters for PUSCH / PUCCH / SRS, or each contains only one set of power control parameters for PUSCH / PUCCH / SRS (e.g., a first power control parameter set / a third power control parameter set / a fifth power control parameter set exists, but a second power control parameter set / a fourth power control parameter set / a sixth power control parameter set does not exist). The following configuration is not allowed: some uplink power control information elements contain two sets of power control parameters for PUSCH / PUCCH / SRS, while other uplink power control information elements contain only one set of power control parameters for PUSCH / PUCCH / SRS (a first power control parameter set / a third power control parameter set / a fifth power control parameter set).

[0092] For example, if one uplink power control information element in a cell contains a second set of power control parameters for PUSCH, then other uplink power control information elements in that cell will also contain a second set of power control parameters for PUSCH. Similarly, if one uplink power control information element in a cell contains two sets of power control parameters for PUSCH, then other uplink power control information elements in that cell will also contain two sets of power control parameters for PUSCH. This example uses PUSCH; the same applies to PUCCH / SRS.

[0093] In some embodiments (for the specific cell), the number of power control parameter sets for PUSCH / PUCCH / SRS present in an uplink power control information element is the same. For example, when there are two power control parameter sets for PUSCH in an uplink power control information element, the uplink power control information element also contains two power control parameter sets for PUCCH and / or two power control parameter sets for SRS.

[0094] In some embodiments (for the specific cell), an uplink power control information element must simultaneously contain or not contain two or three of the following: the second power control parameter set, the fourth power control parameter set, and the sixth power control parameter set. For example, if the uplink power control information element contains the first power control parameter set for the PUSCH, it may also contain the fourth power control parameter set for the PUCCH and / or the sixth power control parameter set for the SRS.

[0095] In some embodiments, (for the specific cell) each uplink power control information element independently contains the first power control parameter set / the third power control parameter set / the fifth power control parameter set and / or the second power control parameter set / the fourth power control parameter set / the sixth power control parameter set.

[0096] In some embodiments, (for the specific cell) the first power control parameter set / third power control parameter set / fifth power control parameter set and / or the second power control parameter set / fourth power control parameter set / sixth power control parameter set are independently absent in each uplink power control information element.

[0097] For example, the following configurations are allowed: a portion of the uplink power control information elements of the cell contains a second power control parameter set / a fourth power control parameter set / a sixth power control parameter set, or a portion of the uplink power control information elements does not contain a second power control parameter set / a fourth power control parameter set / a sixth power control parameter set; and / or a portion of the uplink power control information elements of the cell contains two power control parameter sets for PUSCH / PUCCH / SRS, and a portion of the uplink power control information elements contains only one power control parameter set for PUSCH / PUCCH / SRS (a first power control parameter set / a third power control parameter set / a fifth power control parameter set).

[0098] Table 1 provides examples of how the serving cell configuration includes one or more uplink power control information elements and how the uplink power control information elements include a set of power control parameters. Here, 'Cond SBFD' indicates that the corresponding power control parameter set (second power control parameter set / fourth power control parameter set / sixth power control parameter set) is optional when the corresponding serving cell is a specific cell; otherwise, it does not exist. Alternatively, 'Cond SBFD' indicates that the corresponding power control parameter set (second power control parameter set / fourth power control parameter set / sixth power control parameter set) is mandatory when the corresponding serving cell is a specific cell; otherwise, it does not exist.

[0099] Table 1

[0100] In some embodiments, the specific cell includes a cell configured with a first time domain resource and / or a second time domain resource; however, this application is not limited thereto, and for example, the specific cell may also include other cells.

[0101] The following describes the first time domain resources and / or the second time domain resources.

[0102] In some embodiments, the frequency domain resources used for uplink are different in the first time domain resources and the second time domain resources, and / or the beams corresponding to the first time domain resources and the second time domain resources are different.

[0103] For example, in the second time domain resources, the frequency domain resources used for uplink include the first frequency domain resources and / or the third frequency domain resources, and the frequency domain resources used for downlink include the second frequency domain resources and / or the fourth frequency domain resources. However, in the first time domain resources, the frequency domain resources are not divided in the above way. That is, at the same time, all frequency domain resources (PRBs) of the carrier / (active) UL BWP are used for uplink, or all frequency domain resources (PRBs) of the carrier / (active) UL BWP are used for downlink.

[0104] For example, a beam refers to the beam used by the UE to receive or transmit signals. For downlink, the beam is used to receive downlink signals, or the beam is either a downlink beam or a receive beam. For uplink, the beam is used to transmit uplink signals, or the beam is either an uplink beam or a transmit beam. The beams corresponding to the first time-domain resource and the second time-domain resource are different, including that their corresponding uplink and / or downlink beams are different. For example, the beam corresponding to the SBFD symbol is used to transmit the SRS resource associated with the SBFD symbol, and the beam corresponding to the non-SBFD symbol is used to transmit the SRS resource associated with the non-SBFD symbol.

[0105] In some embodiments, the beam may be replaced by TCI state (TCI-State), and / or UL TCI state (TCI-UL-State), and / or QCL information (QCL-Info), and / or QCL parameters (for QCL Type A / B / C / D), and / or QCL sources (for QCL Type A / B / C / D), and / or (QCL Type A / B / C / D) (QCL / spatial filter) reference signals (e.g., SSB (available for downlink and / or uplink), (NZP) CSI-RS (available for downlink and / or uplink), SRS (available for downlink and / or uplink, or, available only for uplink), and / or spatial relationship info), and / or reference signal information, and / or spatial filter.

[0106] For downlink and uplink, the beam can be replaced with the same or different terms mentioned above. For example, for downlink, the (downlink) beam is replaced with TCI state, and for uplink, the (uplink) beam is replaced with UL TCI state. For example, for both uplink and downlink, the beam is replaced with TCI state. Yet another example is that for downlink, the beam is replaced with QCL information or QCL parameters, and for uplink, the beam is replaced with spatial relationship information, reference signal information, or spatial filters, and so on. Other combinations are not listed here.

[0107] For example, the first time-domain resource and the second time-domain resource correspond to different QCL information and / or QCL parameters.

[0108] For example, the same TCI state may include different (QCL Type A / B / C / D) (QCL information and / or (QCL Type A / B / C / D) QCL reference signals and / or (QCL Type A / B / C / D) QCL parameters, with different QCL information and / or QCL parameters corresponding to / applied to the first time domain resource and the second time domain resource, respectively. For example, suppose the same TCI state includes two sets of (QCL Type A / B / C / D) QCL information and / or QCL parameters, one set applied to the first time domain resource and the other set used for the second time domain resource. One set of QCL information may include one or two sets of QCL information, for example, two sets of QCL information corresponding to or included in qcl-Type1 and qcl-Type2, respectively. This TCI state may be configured, for example, by dl-OrJointTCI-StateList(-17), but is not limited thereto.

[0109] For example, the first time-domain resource and the second time-domain resource correspond to different reference signal information and / or spatial filters. For example, the same UL TCI state includes different reference signal information and / or reference signals and / or spatial filters, which correspond to / are applied to the first time-domain resource and the second time-domain resource, respectively. For example, suppose the same UL TCI state includes two reference signal information and / or reference signals and / or spatial filters, one applied to the first time-domain resource and the other to the second time-domain resource. This UL TCI state is configured, for example, by ul-TCI-StateList(-r17), but is not limited to this.

[0110] In some embodiments, for a cell or carrier, in the second time domain resources, different frequency domain resources are respectively (only) used for (network device receiving) uplink (e.g., corresponding to the first frequency domain resources described below) and (only) used for (network device transmitting) downlink (e.g., corresponding to the second frequency domain resources described below). For example, the network device can simultaneously receive (uplink signals) in the frequency domain resources (only) used for uplink and transmit (downlink signals) in the frequency domain resources (only) used for downlink. The first time domain resources are outside the second time domain resources. For example, in the first time domain resources, different frequency domain resources are all used for uplink or all used for downlink. That is, the frequency domain resources are not divided into frequency domain resources (only) used for uplink and (only) used for downlink, and the network device does not receive and transmit at the same time.

[0111] In some embodiments, the first time-domain resource and the second time-domain resource may also be referred to as the first symbol and the second symbol, respectively, that is, the symbol type includes the first symbol and the second symbol. For example, SBFD symbol (second symbol) and non-SBFD symbol (first symbol). However, this application is not limited to this and can also be applied to other scenarios. For example, the first time-domain resource and the second time-domain resource may respectively refer to different time-domain resources defined in other ways. For convenience, the symbols "SBFD symbol" and "non-SBFD symbol" will be used in the following description.

[0112] In some embodiments, information for configuring SBFD symbols and / or non-SBFD symbols is provided by higher-layer signaling. For example, higher-layer parameters for configuring SBFD symbols may optionally exist in SIB1 and / or the SIB ServingCellConfigCommonSIB IE and / or the ServingCellConfigCommon IE (within the ServingTDD-UL-DL-ConfigCommon IE, which contains the TDD-UL-DL-Pattern IE), and / or, higher-layer parameters for configuring SBFD symbols may optionally exist in the ServingCellConfig.

[0113] In some embodiments, a cell / carrier can be configured with one or more (e.g., two) TDD uplink / downlink patterns. When multiple patterns are configured, different patterns may or may not have corresponding SBFD symbols, and different patterns are independently configured with corresponding SBFD symbols.

[0114] For example, for each pattern with SBFD symbols, the configured SBFD symbols are continuous within the corresponding period of the pattern. The high-level parameters for configuring SBFD symbols mentioned above include, for example, one or more parameters for configuring SBFD symbols in that period, such as: start slot index, start symbol index (in the start slot), end slot index, and end symbol index (in the end slot).

[0115] For example, the start and end slots are the first and last slots containing SBFD symbols, respectively. The start and end symbols are the first and last SBFD symbols in the start slot and the last SBFD symbol in the end slot, respectively. All symbols from the start symbol of the start slot to the end symbol of the end slot are SBFD symbols. The slot index is the number of the slots included in the period, which increments by 1, for example, starting from 0 or 1. For example, when the start slot index is 0, the start slot is the first slot in the period; when the start slot index is 1, the start slot is the second slot in the period, and so on. Similarly, the symbol index is the number of the symbols within a slot. The aforementioned slots / symbols use the SCS configured in the reference subcarrier spacing field of the Common TDD Uplink / Downlink Configuration (TDD-UL-DL-Config Common) IE.

[0116] For example, each / different pattern is configured with a period independently, for example, by the corresponding ((TDD-UL-DL-Pattern)IE)dl-UL-TransmissionPeriodicity. When only one pattern is configured, the period of the SBFD symbol is the same as the period corresponding to that pattern; when multiple patterns (e.g., two) are configured, the period of the SBFD symbol is the same as the sum of the periods corresponding to all patterns.

[0117] In some embodiments, a downlink symbol is, for example, a symbol indicated as downlink by the first uplink / downlink configuration, an uplink symbol is, for example, a symbol indicated as uplink by the first uplink / downlink configuration, and a flexible symbol is, for example, a symbol that is neither indicated as downlink nor as uplink by the first uplink / downlink configuration, or a symbol indicated as flexible by the configuration. The first uplink / downlink configuration is used to provide cell-specific uplink / downlink configurations, such as tdd-UL-DL-ConfigurationCommon, or the common TDD uplink / downlink configuration (TDD-UL-DL-ConfigCommon)IE or (TDD-UL-DL-Pattern)IE, but is not limited thereto.

[0118] In some embodiments, the UE determines the DL / UL / Flexible symbol corresponding to the BWP based on the DL / UL / Flexible symbol configured according to the aforementioned reference Subcarrier Spacing (and assuming NCP). For example, it determines the DL / UL / Flexible symbol corresponding to the BWP based on the reference Subcarrier Spacing and the SCS and / or CP type (NCP or ECP) ​​of the BWP.

[0119] In some embodiments, the DL / UL / Flexible symbol refers to the DL / UL / Flexible symbol configured based on the reference SubcarrierSpacing or the DL / UL / Flexible symbol corresponding to the BWP.

[0120] In some embodiments, the UE determines the SBFD / non-SBFD symbol corresponding to the BWP based on the SBFD / non-SBFD symbol configured based on the aforementioned reference Subcarrier Spacing (and assuming NCP). For example, it determines the SBFD / non-SBFD symbol corresponding to the BWP based on the reference Subcarrier Spacing and the SCS and / or CP type (NCP or ECP) ​​of the BWP.

[0121] In some embodiments, SBFD / non-SBFD symbols refer to SBFD / non-SBFD symbols configured based on reference SubcarrierSpacing or SBFD / non-SBFD symbols corresponding to BWP.

[0122] In some embodiments, the UE does not expect the CP type of the BWP to be ECP.

[0123] In some embodiments, the UE does not expect the SBFD symbols configured (as described above by the higher-layer parameters) to overlap with the uplink symbols, or if the SBFD symbols configured (as described above by the higher-layer parameters) overlap with the uplink symbols, the UE considers the SBFD symbols overlapping with the uplink symbols to be non-SBFD symbols.

[0124] In some embodiments, the SBFD symbol overlaps with the downlink symbol or the flexible symbol, or in other words, the SBFD symbol is configured within the scope of the downlink symbol and / or the flexible symbol.

[0125] In some embodiments, SBFD symbols include DL SBFD symbols and / or Flexible SBFD symbols, and non-SBFD symbols include Full-DL symbols and / or Full-Flexible symbols and / or Full-UL symbols (or UL symbols). Other representations may also be used for these symbols, and are not limited thereto.

[0126] Figure 3 is an example diagram of the time-domain resources of an embodiment of this application. As shown in Figure 3, a period (e.g., the period corresponding to a pattern) may include multiple different symbols. Among them, the SBFD symbol falls within the range of downlink symbols and flexible symbols. SBFD symbols overlapping with DL symbols are represented as DL SBFD symbols, SBFD symbols overlapping with flexible symbols are represented as Flexible SBFD symbols, downlink symbols not overlapping with SBFD symbols are represented as Full-DL symbols, flexible symbols not overlapping with SBFD symbols are represented as Full-Flexible symbols, and UL symbols not overlapping with SBFD symbols are represented as Full-UL symbols (assuming that UL symbols cannot be used as SBFD symbols, Full-UL symbols are equivalent to UL symbols). Figure 3 exemplarily illustrates the time-domain resources of an embodiment of this application, but is not limited thereto.

[0127] The frequency domain resources involved in the embodiments of this application are illustrated below.

[0128] For a cell and / or carrier, in the second time domain resources, the first frequency domain resources are used (only) for uplink and the second frequency domain resources are used (only) for downlink. That is, the frequency domain resources are divided into first frequency domain resources (only) used for uplink and second frequency domain resources (only) used for downlink. The first time domain resources are outside the second time domain resources; that is, in the first time domain resources, the frequency domain resources are not divided in the above manner.

[0129] For example, the first frequency domain resource includes the uplink subband (UL subband), and the second frequency domain resource includes the downlink subband (DL subband). Other names may also be used, and this is not a limitation. For convenience, the following descriptions will use UL subband and DL subband.

[0130] In some embodiments, the UE receives information for configuring the UL subband and DL subband. For example, the uplink subband and downlink subband each include an integer number of PRBs, and the information for configuring the UL subband and DL subband includes information indicating the corresponding starting PRB and bandwidth / size (including the number of PRBs).

[0131] In some embodiments, information for configuring the UL subband and DL subband is provided by higher-level signaling.

[0132] For example, higher-layer parameters used to configure the DL subband may optionally exist in SIB1 (the SIB ServingCellConfigCommonSIB IE, the SIB DownlinkConfigCommonSIB IE, the SIB DownlinkFrequencyInfoDL-SIB IE, and the SCS-SpecificCarrier IE), and the inclusion relationship of the above parameters can be expressed as: SIB1 > ServingCellConfigCommonSIB > DownlinkConfigCommonSIB > FrequencyInfoDL-SIB > SCS-SpecificCarrier; and / or,

[0133] The higher-layer parameters used to configure the DL subband may optionally exist in the ServingCellConfigCommon IE (which contains the DownlinkConfigCommon IE, which contains the DownlinkFrequencyInfoDL IE, which contains the SCS-SpecificCarrier IE)). For example, the inclusion relationship of the above parameters can be represented as: ServingCellConfigCommon > DownlinkConfigCommon > FrequencyInfoDL > SCS-SpecificCarrier, and / or, optionally, in the ServingCellConfig. That is, the higher-layer parameters used to configure the DL subband may optionally exist in one or more of the above parameters.

[0134] For example, the higher-layer parameters used to configure the UL subband may optionally exist in SIB1 (the SIB ServingCellConfigCommonSIB IE, the SIB UplinkConfigCommonSIB IE, the SIB UplinkFrequencyInfoUL-SIB IE, and the SCS-SpecificCarrier IE). For instance, the inclusion relationship of these parameters can be expressed as: SIB1 > ServingCellConfigCommonSIB > UplinkConfigCommonSIB > FrequencyInfoUL-SIB > SCS-SpecificCarrier, and / or...

[0135] The higher-layer parameters used to configure the UL subband may optionally exist in the ServingCellConfigCommon IE (which contains the CommonUplinkConfigCommon IE, which contains the UplinkFrequencyInfoUL IE, which contains the SCS-SpecificCarrier IE)). For example, the inclusion relationship of the above parameters can be represented as: ServingCellConfigCommon > UplinkConfigCommon > FrequencyInfoUL > SCS-SpecificCarrier, and / or, optionally, in the ServingCellConfig. That is, the higher-layer parameters used to configure the UL subband may optionally exist in one or more of the above parameters.

[0136] In some embodiments, the high-level parameters for configuring the UL subband and the high-level parameters for configuring the DL subband include one or more parameters for providing the RIV (resource indication value) and / or (the SCS corresponding to the UL / DL subband), that is, indicating the starting RB (RB) of the UL subband and the DL subband respectively based on the RIV. start ) and bandwidth (including the number of RBs, L RBs )).

[0137] For example, resource indicator values ​​can be defined as shown in Table 2 below.

[0138] Table 2

[0139] For example, for DL / UL subband: assuming the following in Table 2 In addition, the first PRB (RB) start The minimum value (0 or 1) corresponding to the PRB can be determined as follows: The first PRB is the PRB determined by the corresponding subcarrierSpacing and offsetToCarrier in ServingCellConfigCommon / ServingCellConfigCommonSIB (configured in the corresponding SCS-Specific Carrier in FrequencyInfoDL (for DL ​​subband) / FrequencyInfoUL (for UL subband) / FrequencyInfoUL-SIB (for UL subband) / FrequencyInfoDL-SIB (for DL ​​subband)).

[0140] In some embodiments, within a cell, the scs-SpecificCarrierList of UL and DL may each include one or more SCS-SpecificCarrier IEs, and each SCS-SpecificCarrier IE corresponds to / includes one SCS configuration (subcarrierSpacing). That is, the scs-SpecificCarrierList of UL and DL may each include one or more SCS configurations.

[0141] For example, each SCS configuration in the UL scs-SpecificCarrierList is configured with a UL subband, or each corresponds to a UL subband, for example, each corresponds to an independent high-level parameter mentioned above for configuring the UL subband. Each SCS configuration in the DL scs-SpecificCarrierList is configured with one or more (e.g., two) DL subbands, or each corresponds to one or more DL subbands, for example, each corresponds to an independent high-level parameter mentioned above for configuring the DL subband. If an SCS configuration is configured with multiple DL subbands, the corresponding high-level parameter for configuring the DL subband includes multiple RIVs mentioned above.

[0142] In some embodiments, the UE does not expect the DL subband and UL subband (in the frequency domain) to overlap (for the same SCS (configuration), or the UE expects the DL subband and UL subband (in the frequency domain) not to overlap (for the same SCS (configuration)).

[0143] In some embodiments, in the second time domain resource, the first frequency domain resource and / or the third frequency domain resource (UL usable PRBs for the active UL BWP) are used for uplink and the second frequency domain resource and / or the fourth frequency domain resource (DL usable PRBs for the active DL BWP) are used for downlink, and the first time domain resource is outside the second time domain resource. For convenience, UL usable PRBs and DL usable PRBs will be used in the following description.

[0144] In some embodiments, for a UL BWP, its UL usable PRBs include / are determined as (in the SBFD symbol / corresponding to the SBFD symbol,) the intersection of (PRBs in the UL subband) and (PRBs in the uplink BWP) with (the SCS configured for the uplink BWP, or, corresponding to the SCS of the UL BWP), or, the PRBs in the intersection are referred to as UL usable PRBs.

[0145] For example, for a UL BWP, the intersection is determined based on the uplink subband corresponding to the SCS of that UL BWP. For instance, if the SCS of a UL BWP is 15kHz, then its corresponding UL available PRB is the intersection of that UL BWP and the corresponding uplink subband with SCS = 15kHz. If the SCS of a UL BWP is 30kHz, then its corresponding UL available PRB is the intersection of that UL BWP and the corresponding uplink subband with SCS = 15kHz.

[0146] In some embodiments, the UE does not expect the UL usable PRBs of the activated UL BWP and the DL usable PRBs of the activated DL BWP to overlap or their frequency domain spacing to be less than or greater than a specific value; or, the UE expects the UL usable PRBs of the activated UL BWP and the DL usable PRBs of the activated DL BWP to not overlap or their frequency domain spacing to be not less than or greater than a specific value.

[0147] In some embodiments, for a UL BWP, if the PRBs in the UL subband (configured for the SCS of the uplink BWP, or corresponding to the SCS of the UL BWP) have no intersection with the PRBs in the uplink BWP, or if the intersection of the PRBs in the UL subband (configured for the SCS of the uplink BWP, or corresponding to the SCS of the UL BWP) with the PRBs in the uplink BWP includes 0 PRBs, then the UL BWP does not have UL usable PRBs; otherwise, if there is an intersection or the intersection includes at least 1 PRB or more than 0 PRBs, the UL BWP has UL usable PRBs.

[0148] Figure 4 is an example diagram of uplink usable PRBs according to an embodiment of this application. As shown in Figure 4, the UL BWP and UL subband overlap, and the UL usable PRBs are the intersection between them. The UL subband, for example, represents the uplink subband corresponding to the SCS of the UL BWP, but this application is not limited to this.

[0149] In some embodiments, for a DL BWP, its DL usable PRBs include / are determined as (in SBFD symbols / corresponding to SBFD symbols,) the intersection of (PRBs in the DL subband) and (PRBs in the downlink BWP) with (the SCS configured for the downlink BWP, or, corresponding to the SCS of the DL BWP), or, the PRBs in the intersection are referred to as DL usable PRBs.

[0150] For example, for a DL BWP, the intersection is determined based on the downlink subband corresponding to the SCS of that DL BWP. For instance, if the SCS of a DL BWP is 15kHz, then its corresponding DL can be represented by the PRB as the intersection of the DL BWP with the corresponding downlink subband of SCS = 15kHz. If the SCS of a DL BWP is 30kHz, then its corresponding DL can be represented by the PRB as the intersection of the DL BWP with the corresponding uplink subband of SCS = 15kHz.

[0151] Figure 5 is an example diagram of downlink usable PRBs according to an embodiment of this application. As shown in Figure 5, DL BWP and DL subband overlap, and DL usable PRBs are the intersection of the two. The DL subband, for example, represents the downlink subband corresponding to the SCS of the DL BWP, but this application is not limited thereto.

[0152] In the embodiments of this application, overlap with the SBFD symbol includes partial overlap (i.e., the part is within the SBFD symbol and a part is within the non-SBFD symbol) and / or complete overlap (also, it can be said that it is within the SBFD symbol). Overlap with the non-SBFD symbol includes partial overlap (i.e., the part is within the non-SBFD symbol and a part is within the SBFD symbol) and / or complete overlap (also, it can be said that it is within the non-SBFD symbol).

[0153] In some embodiments, overlap with SBFD symbols and overlap with non-SBFD symbols do not both include the aforementioned partial overlap. For example, if overlap with SBFD symbols includes partial overlap, then overlap with non-SBFD symbols does not include partial overlap, and vice versa; this application is not limited thereto.

[0154] The above provides an illustrative description of time and frequency resources. The following provides a further illustrative description of the embodiments of this application.

[0155] Figure 6 is an example diagram of a power headroom report according to an embodiment of this application, illustrated using the interaction between the gNB and the UE as an example. As shown in Figure 6, the gNB can send configuration information (as shown in 601) via RRC signaling. This configuration information includes, for example:

[0156] - For a cell group or MAC entity: PHR-Config, etc.;

[0157] - For a single cell: TDD configuration, SBFD symbol / non-SBFD symbol configuration, DL / UL subband configuration, BWP configuration, unified TCI state type (unifiedTCI-StateType), uplink power control configuration (uplink-PowerControlToAddModList), etc.

[0158] The UE can calculate a first power margin and / or a second power margin for the cell (as shown in 602). For details on how to calculate this, please refer to the following methods. The UE can send the first power margin and / or the second power margin for the cell to the gNB (as shown in 603), for example, by carrying the PHR via MAC CE.

[0159] It is worth noting that Figure 6 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 6 above.

[0160] In this embodiment of the application, the terminal device may send one (Type 1) power margin of the cell, or it may send two (Type 1) power margins of the cell. The power margin includes: a first (Type 1) power margin associated with the first power control parameter set (or, power margin report PHR), and / or a second (Type 1) power margin associated with the second power control parameter set.

[0161] In some embodiments, the cell is a specific cell, and / or the cell is a Pcell / PScell / SpCell / PUCCH-Scell / Scell / primary cell / serving cell, and / or the cell has a configured uplink (or may also be referred to as having an uplink configuration), and / or the cell is an active serving cell, and / or the active DL BWP of the cell is not a dormant BWP.

[0162] In some embodiments, the first power margin associated with the first power control parameter set includes: the first power margin associated with the first power control parameter set associated with the indicated TCI state or UL TCI state; the second power margin associated with the second power control parameter set includes: the second power margin associated with the second power control parameter set associated with the indicated TCI state or UL TCI state.

[0163] For example, the terminal device sends one or two power margins of the cell, wherein the one or two power margins include: a first power margin associated with the first set of power control parameters associated with the indicated TCI state or UL TCI state, and / or a second power margin associated with the second set of power control parameters associated with the indicated TCI state or UL TCI state.

[0164] In some embodiments, the indicated TCI state and / or UL TCI state is one of the cell's (active DL BWP) TCI state and / or (NUL / non-SUL) (carrier) (active UL BWP) UL TCI state.

[0165] In some embodiments, the TCI state can be configured, for example, through TCI-State (IE), and the TCI state can also be referred to as TCI-State (IE). Similarly, the UL TCI state can be configured, for example, through TCI-UL-State (IE), and the UL TCI state can be referred to as TCI-UL-State (IE).

[0166] In some embodiments, the TCI state of a cell is configured separately for each DL BWP, and the UL TCI state is configured separately for each UL BWP. For example, the configuration information of the DL BWP (in the PDSCH-Config) may include dl-OrJointTCI-StateList(-r17), which may include one or more TCI-States (IEs). Similarly, the configuration information of the UL BWP may include ul-TCI-StateList(-r17), which may include one or more TCI-UL-States (IEs). The TCI state and / or UL TCI state of a cell includes all TCI states and / or UL TCI states configured for (all) DL BWPs / UL BWPs of that cell.

[0167] In some embodiments, if the serving cell configuration of a cell includes a unified TCI state type (unifiedTCI-StateType-r17), it indicates that the cell is configured with a unified TCI state, and unifiedTCI-StateType-r17 can be configured as either separate or joint. When configured as separate, the TCI state applies to downlink, and the UL TCI state applies to uplink. For example, the configuration information of the DL BWP (in its PDSCH-Config) may include dl-OrJointTCI-StateList-r17, and the configuration information of the UL BWP may include ul-TCI-StateList-r17. When configured as joint, the TCI state applies to both downlink and uplink. For example, the configuration information of the DL BWP (in its PDSCH-Config) may include dl-OrJointTCI-StateList-r17, and its configured TCI state also applies to the UL BWP paired with it. The configuration information of the UL BWP does not include ul-TCI-StateList (-r17).

[0168] In some embodiments, DL BWPs and UL BWPs with the same BWP ID are paired. For example, each DL BWP includes a higher-layer parameter bwp-Id for configuring its BWP ID, which uniquely identifies a DL BWP within a cell, and each UL BWP's configuration information includes a higher-layer parameter bwp-Id for configuring its BWP ID, which uniquely identifies a UL BWP within a cell. If a DL BWP and a UL BWP have the same configured BWP ID value, they are paired. For example, a DL BWP with bwp-Id = 0 is paired with a UL BWP with bwp-Id = 0, a DL BWP with bwp-Id = 1 is paired with a UL BWP with bwp-Id = 1, and so on.

[0169] In some embodiments, the TCI-State IE and TCI-UL-State IE may each include parameters such as pathlossReferenceRS-Id-r17 (configuring the first path loss reference signal), pathlossReferenceRS-Id-r19 / pathlossReferenceRS-Id-SBFD / (configuring the second path loss reference signal)ul-powerControl-r17. Specifically, when the unified TCI state type is independent, the TCI-State IE does not include / does not contain pathlossReferenceRS-Id-r17 (and pathlossReferenceRS-Id-r19), while the TCI-UL-State IE includes pathlossReferenceRS-Id-r17 (optionally present). When the unified TCI state type is joint, the TCI-State IE includes (forces to exist) pathlossReferenceRS-Id-r17 (optionally present) pathlossReferenceRS-Id-r19.

[0170] In some embodiments, the indicated TCI state and / or UL TCI state refers to the TCI state or UL TCI state indicated by RRC signaling, MAC CE, or DCI. For example, when dlOrJointTCI-StateList-r17 includes only one TCI-State, that TCI-State can be used as the indicated TCI-State; when ul-TCI-StateList-r17 includes only one TCI-UL-State, that TCI-UL-State can be used as the indicated TCI-UL-State. For example, (when dlOrJointTCI-StateList includes multiple TCI-States, and / or ul-TCI-StateList-r17 includes multiple TCI-UL-States), when the activation command (MAC CE) maps the TCI-State and / or TCI-UL-State to only one TCI codepoint (or only one TCI-State and / or TCI-UL-State is activated), that TCI-State and / or TCI-UL-State is used as the indicated TCI-State and / or TCI-UL-State. For example, (when dlOrJointTCI-StateList-r17 includes multiple TCI-States, and / or ul-TCI-StateList-r17 includes multiple TCI-UL-States, and / or when the activation command (MAC CE) maps TCI-States and / or TCI-UL-States to multiple TCI codepoints (or multiple TCI-States and / or TCI-UL-States are activated, and / or the DCI includes information fields for indicating TCI-States and / or TCI-UL-States),) the TCI-States and / or TCI-UL-States indicated by the DCI (format 1_1 / 1_2 / 1_3) can be used as the indicated TCI-States and / or TCI-UL-States.

[0171] In some embodiments, the TCI state or UL TCI state may be associated with a set of power control parameters.

[0172] In some embodiments, all TCI states of the cell (active DL BWP) or all UL TCI states of the carrier (active UL BWP) are associated with two sets of power control parameters for PUSCH (including a first set of power control parameters and a second set of power control parameters) and / or two sets of power control parameters for PUCCH (including a third set of power control parameters and a fourth set of power control parameters) and / or two sets of power control parameters for SRS (including a fifth set of power control parameters and a sixth set of power control parameters).

[0173] In some embodiments, a portion of the TCI state (of the active DL BWP) or a portion of the UL TCI state (of the carrier) (of the active UL BWP) of the cell is associated with two sets of power control parameters for the PUSCH (including a first power control parameter set and a second power control parameter set) and / or two sets of power control parameters for the PUCCH (including a third power control parameter set and a fourth power control parameter set) and / or two sets of power control parameters for the SRS (including a fifth power control parameter set and a sixth power control parameter set), and another portion of the TCI state (of the active DL BWP) or another portion of the UL TCI state (of the carrier) (of the active UL BWP) of the cell is associated with one set of power control parameters for the PUSCH (including a first power control parameter set or a second power control parameter set) and / or one set of power control parameters for the PUCCH (including a third power control parameter set or a fourth power control parameter set) and / or one set of power control parameters for the SRS (including a fifth power control parameter set or a sixth power control parameter set).

[0174] In some embodiments, all TCI states of the cell (active UL BWP) or all UL TCI states of the carrier (active UL BWP) are associated with a power control parameter set for the PUSCH (including a first power control parameter set or a second power control parameter set) and / or a power control parameter set for the PUCCH (including a third power control parameter set or a fourth power control parameter set) and / or a power control parameter set for the SRS (including a fifth power control parameter set or a sixth power control parameter set).

[0175] In some embodiments, the set of power control parameters associated with a TCI state (for PUSCH) includes: a set of power control parameters (for PUSCH) corresponding to the uplink power control identifier in the UL BWP that is paired with the DL BWP where the TCI state is located; or, a set of power control parameters (for PUSCH) corresponding to the uplink power control identifier in the TCI state.

[0176] In some embodiments, the set of power control parameters associated with a TCI state (for PUSCH) includes: the set of power control parameters (for PUSCH) corresponding to the uplink power control identifier in the UL BWP where the UL TCI state is located, or the set of power control parameters (for PUSCH) corresponding to the uplink power control identifier in the UL TCI state.

[0177] For example, there are two ways to configure the set of power control parameters associated with TCI state or UL TCI state.

[0178] Method 1: The configuration information of the UL BWP includes a higher-layer parameter ul-powerControl-r17 that indicates the power control parameters for PUSCH / PUCCH / SRS of the UL BWP. The uplink power control identifier provided by this higher-layer parameter points to the uplink power control information element with the same uplink power control identifier in the uplink-PowerControlToAddModList-r17 of the corresponding cell and / or the set of power control parameters for PUSCH / PUCCH / SRS included in the uplink power control information element.

[0179] Therefore, when the unified TCI state type is independent, all UL TCI states of this UL BWP are associated with the power control parameter set for PUSCH / PUCCH / SRS pointed to / corresponding to by the uplink power control identifier. When the unified TCI state type is joint, all TCI states of the DL BWP paired with this UL BWP are associated with the power control parameter set for PUSCH / PUCCH / SRS pointed to / corresponding to by the uplink power control identifier.

[0180] Method 2: The configuration information of the UL BWP does not include the high-level parameter ul-powerControl-r17, which is used to indicate the power control parameters for PUSCH / PUCCH / SRS of the UL BWP.

[0181] When the unified TCI state type is independent, the TCI-UL-State(IE) includes the higher-layer parameter ul-powerControl-r17 of the power control parameters for PUSCH / PUCCH / SRS in that (UL) TCI state. The uplink power control identifier provided by this higher-layer parameter points to the uplink power control information element with the same uplink power control identifier in the corresponding cell's uplink-PowerControlToAddModList-r17 and / or the set of power control parameters for PUSCH / PUCCH / SRS included in that uplink power control information element. Therefore, the UL TCI state is associated with the set of power control parameters for PUSCH / PUCCH / SRS pointed to / corresponding to by the uplink power control identifier.

[0182] When the unified TCI state type is joint, the TCI-State (IE) includes the higher-layer parameter ul-powerControl-r17, which contains the power control parameters for PUSCH / PUCCH / SRS for that TCI state. The uplink power control identifier provided by this higher-layer parameter points to the uplink power control information element with the same uplink power control identifier in the corresponding cell's uplink-PowerControlToAddModList-r17 and / or the set of power control parameters for PUSCH / PUCCH / SRS included in that uplink power control information element. Therefore, this TCI state is associated with the set of power control parameters for PUSCH / PUCCH / SRS pointed to / corresponding to by the uplink power control identifier.

[0183] In some embodiments, the indicated TCI state or UL TCI state is associated with two sets of power control parameters for the PUSCH (including a first power control parameter set and a second power control parameter set) and / or two sets of power control parameters for the PUCCH (including a third power control parameter set and a fourth power control parameter set) and / or two sets of power control parameters for the SRS (including a fifth power control parameter set and a sixth power control parameter set). Alternatively, it can be described as (equivalent to) that the TCI state or UL TCI state is associated with a second power control parameter set and / or a fourth power control parameter set and / or a sixth power control parameter set.

[0184] In some embodiments, the indicated TCI state or UL TCI state is associated with a set of power control parameters for the PUSCH (including a first set of power control parameters or a second set of power control parameters) and / or a set of power control parameters for the PUCCH (including a third set of power control parameters or a fourth set of power control parameters) and / or a set of power control parameters for the SRS (including a fifth set of power control parameters or a sixth set of power control parameters). Alternatively, it can be described as (equivalent to) that the TCI state or UL TCI state is not associated with the second set of power control parameters and / or the fourth set of power control parameters and / or the sixth set of power control parameters.

[0185] The following explains how terminal equipment calculates the transmit power of PUSCH / PUCCH / SRS.

[0186] Table 3 illustrates how to calculate PUSCH transmit power, Table 4 illustrates how to calculate PUCCH transmit power, and Table 5 illustrates how to calculate SRS transmit power. Wherein, P... CMAX,f,c (i) represents the maximum transmit / output power (configured by the UE), α b,f,c (j) / α SRS,b,f,c (q s ) represent the road loss compensation factors for PUSCH and SRS, respectively, PL b,f,c (q d ) represents road loss, and l represents the PUSCH power control adjustment state index (i.e., the closed-loop index of PUSCH).

[0187] For PUSCH, P O_PUSCH,b,f,c (j)is a parameter composed of the sum of a component P O_NOMINAL,PUSCH,f,c (j) (cell-specific target power) and a component P O_UE_PUSCH,b,f,c (j)(UE-specific target power). For PUCCH, P O_PUCCH,b,f,c (q u )is a parameter composed of the sum of a component P O_NOMINAL,PUCCH (Cell-specific target power) and a component P O_UE_PUCCH (q u (UE-specific target power). For SRS, P O_SRS,b,f,c (q s)is the sum of the component P O_UE_SRS,b,f,c (q s )and a component p0 provided by SRS-ResourceSet corresponding to the SRS resource set.

[0188] Table 3

[0189] Table 4

[0190] Table 5

[0191] In some embodiments, the terminal device may calculate the PUSCH / PUCCH / SRS transmit power based on the set of power control parameters (for PUSCH / PUCCH / SRS) associated with the indicated TCI state or UL TCI state and / or the path loss reference signal.

[0192] For example, when the unified TCI state type is joint, the PUSCH / PUCCH / SRS transmit power is calculated based on the power control parameter set (for PUSCH / PUCCH / SRS) associated with the indicated TCI state and / or the path loss reference signal; when the unified TCI state type is independent, the PUSCH / PUCCH / SRS transmit power is calculated based on the power control parameter set (for PUSCH / PUCCH / SRS) associated with the indicated UL TCI state and / or the path loss reference signal.

[0193] In some embodiments, the cell is configured with a first time-domain resource and / or a second time-domain resource, (the cell's (NUL / non-SUL) (carrier-activated UL BWP has UL usable PRBs,)

[0194] When the indicated TCI state or UL TCI state is associated with a set of power control parameters for the PUSCH, the terminal device uses the power control parameter set associated with the indicated TCI state or UL TCI state to determine the transmit power of the PUSCH in the first time domain resource and the PUSCH in the second time domain resource; and / or,

[0195] When the indicated TCI state or UL TCI state is associated with two sets of power control parameters for the PUSCH, the terminal device uses the first set of power control parameters associated with the indicated TCI state or UL TCI state to determine the transmission power of the PUSCH in the first time domain resource, and uses the second set of power control parameters associated with the indicated TCI state or UL TCI state to determine the transmission power of the PUSCH in the second time domain resource.

[0196] Table 6 provides illustrative examples using SBFD and non-SBFD symbols.

[0197] Table 6

[0198] In some embodiments, for PUSCH / PUCCH / SRS in the first time domain resource, the transmission power is calculated using the first maximum transmission power, and for PUSCH / PUCCH / SRS in the second time domain resource, the transmission power is calculated using either the first maximum transmission power (when the second maximum transmission power is not configured) or the second maximum transmission power (when the second maximum transmission power is configured).

[0199] In some embodiments, for PUSCH / PUCCH / SRS in the first time domain resource, path loss is determined and transmission power is calculated based on a first path loss reference signal. For PUSCH / PUCCH / SRS in the second time domain resource, path loss is determined and transmission power is calculated using either the first path loss reference signal (when no second path loss reference signal is configured, or when the indicated TCI state or UL TCI state does not have an associated second path loss reference signal) or the second path loss reference signal (when a second path loss reference signal is configured, or when the indicated TCI state or UL TCI state has an associated second path loss reference signal).

[0200] In some embodiments, TCI-State or UL-TCI-State includes higher-level parameters for configuring the second path loss reference signal.

[0201] In some embodiments, "PUSCH in the first time domain resource", "PUSCH associated with the first power control parameter set", and "PUSCH associated with the first SRS resource set" can be interchanged. "PUSCH in the second time domain resource", "PUSCH associated with the second power control parameter set", and "PUSCH associated with the second SRS resource set" can be interchanged.

[0202] In some embodiments, the first SRS resource set and the second SRS resource set are used as codebooks or non-versioned. The PUSCH in the first time-domain resource and / or associated with the first power control parameter set is associated / related to the first SRS resource set (of the SRS resources), or the first SRS resource set (of the SRS resources) is associated / applied to the first time-domain resource (of the PUSCH). The PUSCH in the second time-domain resource and / or associated with the second power control parameter set is associated / related to the second SRS resource set (of the SRS resources), or the second SRS resource set (of the SRS resources) is associated / applied to the second time-domain resource (of the PUSCH). For example, the first SRS resource set and the second SRS resource set are configured with the same or different higher-level parameters. For example, the first SRS resource set is configured with first higher-level parameters, and the second SRS resource set is configured with second higher-level parameters, where the first higher-level parameters and the second higher-level parameters are the same or different.

[0203] The above explains how to calculate the transmit power of PUSCH / PUCCH / SRS. The following will further explain how to calculate / determine the (Type 1) power margin.

[0204] In some embodiments, the first power margin is associated with a first maximum transmit power, a first path loss reference signal, and a first set of power control parameters. For example, the first power margin is calculated based on the first maximum transmit power, the first path loss reference signal (or path loss determined / acquired based on the first path loss reference signal), and the first set of power control parameters. The second power margin is associated with either the first maximum transmit power or the second maximum transmit power and the first path loss reference signal or the second path loss reference signal and the second set of power control parameters. For example, (when no second maximum transmit power or second path loss reference signal is configured), the second power margin is calculated based on the first maximum transmit power, the first path loss reference signal (or path loss determined / acquired based on the first path loss reference signal), and the second set of power control parameters. Similarly, (when the second maximum transmit power is configured but no second path loss reference signal is configured), the second power margin is calculated based on the second maximum transmit power, the first path loss reference signal (or path loss determined / acquired based on the first path loss reference signal), and the second set of power control parameters.

[0205] In some embodiments, the terminal device determines the first power margin based on actual PUSCH transmission or reference PUSCH transmission, and / or, the terminal device determines the second power margin based on actual PUSCH transmission or reference PUSCH transmission.

[0206] For example, referring to Table 7, a first power margin and / or a second power margin can be calculated based on the actual / real PUSCH transmit power. As another example, referring to Table 8, a first power margin and / or a second power margin can be calculated based on a referenced PUSCH transmit power.

[0207] For example, in the calculation of the first power margin, the value of P CMAX,f,c (i) is provided by the first maximum transmit power, PL b,f,c (q d )is obtained by PL-RS(provided by pathlossReferenceRS-Id-r17)associated with the indicated TCI-State or TCI-UL-State, and / or, the values ​​of P O_UE_PUSCH,b,f,c (j),α b,f,c (j), and the PUSCH power control adjustment state l are provided by p0AlphaSetforPUSCH (first power control parameter set) associated with or included in the indicated TCI-State or TCI-UL-State.

[0208] For example, regarding the calculation of the second power margin, the value of P CMAX,f,c (i) is provided by the first maximum transmit power / the second maximum transmit power, PL b,f,c (q d )is obtained by PL-RS(provided by pathlossReferenceRS-Id-r17 / pathlossReferenceRS-Id-r19)associated with the indicated TCI-State or TCI-UL-State, and / or, values ​​of P O_UE_PUSCH,b,f,c (j),α b,f,c(j), and the PUSCH power control adjustment state l are provided by p0AlphaSetforPUSCH-SBFD (second power control parameter set) associated with or included in the indicated TCI-State or TCI-UL-State.

[0209] Table 7

[0210] Table 8

[0211] The above explains how to calculate (Type 1) power margin. The following further explains how to transmit power margin.

[0212] In some embodiments, when a first condition is met, the terminal device (simultaneously / in a MAC CE) transmits two power margins for the cell; otherwise (when a second condition is met), the terminal device (in a MAC CE) transmits one power margin for the cell.

[0213] For example, the first condition includes at least:

[0215] The terminal device is configured to transmit two power margins (including a first power margin / a second power margin) (simultaneously / in one MAC CE) (for the cell) (e.g., (higher-layer) parameters are provided to indicate the transmission of two power margins (for the cell) simultaneously / in one MAC CE); and / or,

[0216] The terminal device is not configured to send a power margin (for the cell); and / or,

[0217] The terminal device is not configured to determine whether to send a first power margin or a second power margin (e.g., to prioritize sending either the first or second power margin); and / or,

[0218] (The terminal device or the cell) is configured with a unified TCI status (type); and / or,

[0219] (The terminal device or the cell (the active UL BWP)) is configured with two sets of power control parameters (for PUSCH) (e.g., one / at least one / each uplink power control information of the cell includes two sets of power control parameters (for PUSCH), for example, the uplink power control identifier in the active UL BWP corresponds to two sets of power control parameters (for PUSCH)); and / or,

[0220] (The indicated TCI state or UL TCI state of the cell (the active UL BWP) is associated with two sets of power control parameters (for PUSCH); and / or,

[0221] The (NUL / non-SUL) (carrier) activated UL BWP of the cell has UL usable PRBs; and / or,

[0222] The terminal device or the cell or the (NUL / non-SUL) carrier of the cell or the (NUL / non-SUL) (carrier) of the cell is configured with two SRS resource sets (first SRS resource set and second SRS resource set) used as codebooks or two SRS resource sets (first SRS resource set and second SRS resource set) used as non-codebooks.

[0223] For example, the second condition includes at least:

[0224] The terminal device does not support (simultaneously / in one MAC CE) transmitting two power margins (including a first power margin / a second power margin) (for the cell); and / or,

[0225] The terminal device is not configured to transmit two power margins (including a first power margin / a second power margin) (simultaneously / in a MAC CE) for the cell (e.g., no (higher-layer) parameters are provided to indicate the transmission of two power margins (for the cell simultaneously / in a MAC CE); and / or,

[0226] The terminal device is configured to send a power margin (for the cell); and / or,

[0227] The terminal device is configured to determine whether to send a first power margin or a second power margin (e.g., to prioritize sending the first power margin or the second power margin); and / or,

[0228] (The terminal device or the cell) is not configured with a unified TCI status; and / or

[0229] (The terminal device or the cell (the active UL BWP)) is not configured with two sets of power control parameters (for PUSCH) (e.g., one / at least one / each uplink power control information of the cell does not include two sets of power control parameters (for PUSCH), for example, the uplink power control identifier in the active UL BWP does not correspond to two sets of power control parameters (for PUSCH)); and / or,

[0230] The indicated TCI state or UL TCI state of the cell (the active UL BWP) is associated with only one set of power control parameters (for PUSCH); and / or,

[0231] The (NUL / non-SUL) (carrier) activated UL BWP of the cell does not have UL usable PRBs; and / or,

[0232] The terminal device or the cell or the cell's (NUL / non-SUL) carrier or the cell's (NUL / non-SUL) (carrier) active UL BWP) is not configured with two SRS resource sets (first SRS resource set and second SRS resource set) used as codebooks or two SRS resource sets (first SRS resource set and second SRS resource set) used as non-codebooks.

[0233] In some embodiments, the terminal device receives one or more (higher-level) parameters indicating one or more of the following:

[0234] (Simultaneously / within a MAC CE) send two power margins (including a first power margin / a second power margin) (for the cell).

[0235] (In a MAC CE) send a power margin (for the cell).

[0236] How to determine (within a MAC CE) whether to send the first power margin or the second power margin (for the cell) (e.g., prioritize sending the first power margin or the second power margin).

[0237] For example, the (higher-layer) parameters used to indicate the transmission of two power margins (for the cell) simultaneously / in a MAC CE include twoPHRmode, or parameters different from twoPHRmode.

[0238] For example, one or more of the (high-level) parameters may be optional and may exist in the Power Headroom Report Configuration (PHR-Config) information element.

[0239] In some embodiments, when transmitting two power margins of the cell, the two power margins include the first power margin and the second power margin, or two of the first power margin, or two of the second power margin.

[0240] In some embodiments, when the indicated TCI state or UL TCI state is associated with two sets of power control parameters (for PUSCH), the two power margins include the first power margin and the second power margin.

[0241] In some embodiments, when the indicated TCI state or UL TCI state is associated with a power control parameter set (for PUSCH) and the power control parameter set is the first power control parameter set, the two power margins include two of the first power margins.

[0242] In some embodiments, when the indicated TCI state or UL TCI state is associated with a power control parameter set (for PUSCH) and the power control parameter set is the second power control parameter set, the two power margins include two second power margins.

[0243] In some embodiments, when the two power margins include two first power margins or two second power margins:

[0244] If the reference timeslot includes (one or more) actual PUSCH transmissions, the terminal device determines one of the two first power margins or two second power margins based on the (first) actual PUSCH transmission in the reference timeslot, and determines the other first power margin or second power margin based on the referenced PUSCH transmission.

[0245] And / or, if the reference timeslot includes more than one actual PUSCH transmission, the terminal device determines two first power margins or two second power margins based on the same actual PUSCH transmission in the reference timeslot, or determines two first power margins or two second power margins based on different actual PUSCH transmissions in the reference timeslot.

[0246] In some embodiments, the power margin of a cell is transmitted in the cell's PUSCH, or in the PUSCH of another cell.

[0247] In some embodiments, for the cell where the PUSCH for transmitting the MAC CE including the power margin resides, the reference timeslot is the timeslot in which the UE transmits / provides the power margin (i.e., the timeslot in which the PUSCH for transmitting the MAC CE including the power margin resides). For other cells, the reference timeslot is the timeslot in that other cell that overlaps with the timeslot in which the UE transmits / provides the power margin (in the cell where the PUSCH for transmitting the MAC CE including the power margin resides), or the first overlapping timeslot. The reference timeslot is, for example, referred to as slot n.

[0248] In some embodiments, when the two power margins include the first power margin and the second power margin,

[0249] If the reference time slot includes an actual PUSCH transmission associated with the first power control parameter set (equal to the (actual) PUSCH transmission in the first time domain resource, or equal to the (actual) PUSCH transmission associated with the first SRS resource set), the terminal device sends the first power margin based on the first actual PUSCH transmission associated with the first power control parameter set in the reference time slot (determined); otherwise, it sends the first power margin based on the reference PUSCH transmission (determined).

[0250] If the reference time slot includes an actual PUSCH transmission associated with the second power control parameter set (equal to the (actual) PUSCH transmission in the second time domain resource, or equal to the (actual) PUSCH transmission associated with the second SRS resource set), the terminal device sends the first power margin based on the first actual PUSCH transmission associated with the second power control parameter set in the reference time slot (determined); otherwise, it sends the second power margin based on the reference PUSCH transmission (determined).

[0251] In some embodiments, when the terminal device sends a power margin for the cell, the power margin includes either the first power margin or the second power margin.

[0252] In some embodiments, the terminal device determines whether to send the first power margin or the second power margin based on a set of power control parameters (for PUSCH) associated with the indicated TCI state or UL TCI state.

[0253] In some embodiments, when the indicated TCI state or UL TCI state is associated with a set of power control parameters (for PUSCH) and the set of power control parameters is the first set of power control parameters, the power margin includes the first power margin.

[0254] In some embodiments, when the indicated TCI state or UL TCI state is associated with a set of power control parameters (for PUSCH) and the set of power control parameters is the second set of power control parameters, the power margin includes the second power margin.

[0255] In some embodiments, the terminal device determines whether to send the first power margin or the second power margin based on a reference time slot.

[0256] For example, if there is no actual PUSCH transmission in the reference time slot, the terminal device (predefined) sends the first power margin (determined based on the reference PUSCH transmission), or the terminal device sends the second power margin (determined based on the reference PUSCH transmission).

[0257] For example, if there is an actual PUSCH transmission in the reference time slot:

[0258] If a specific (e.g., first / last) actual PUSCH transmission in the reference time slot is associated with the first power control parameter set (in the first time domain resource, or associated with the first SRS resource set), the terminal device sends (based on the specific (e.g., first / last) actual PUSCH transmission) the first power margin; otherwise (if a specific (e.g., first / last) PUSCH transmission in the reference time slot is associated with the second power control parameter set in the second time domain resource, or associated with the second SRS resource set), the terminal device sends (based on the specific (e.g., first / last) actual PUSCH transmission) the second power margin.

[0259] For example, if there is an actual PUSCH transmission in the reference time slot:

[0260] If at least one actual PUSCH transmission in the reference time slot is associated with the first power control parameter set, the terminal device sends (based on a specific (e.g., first / last) actual PUSCH transmission in that at least one actual PUSCH transmission) the first power margin; otherwise (if all PUSCH transmissions in the reference time slot are associated with the second power control parameter set), the terminal device sends (based on a specific (e.g., first / last) actual PUSCH transmission in that reference time slot) the second power margin; and / or,

[0261] If at least one actual PUSCH transmission in the reference time slot is associated with the second power control parameter set, the terminal device sends the second power margin (determined based on a specific (e.g., first / last) actual PUSCH transmission in the at least one actual PUSCH transmission); otherwise (if all PUSCH transmissions in the reference time slot are associated with the first power control parameter set), the terminal device sends the first power margin (determined based on a specific (e.g., first / last) actual PUSCH transmission in the reference time slot).

[0262] In some embodiments, the terminal device does not expect the cell to be configured with a SUL carrier.

[0263] In some embodiments, the terminal device transmits one or two power margins of the cell in a MAC CE, wherein the MAC CE is used to transmit the power margin of one cell (Pcell), or the MAC CE is used to transmit the power margin of one or more cells (Pcell and / or other cells).

[0264] The following examples further illustrate the dual power headroom reporting and single power headroom reporting.

[0265] (For cells that have been configured with first time domain resources and / or second time domain resources:)

[0266] For example, if a UE, cell, or MAC entity is configured (simultaneously / in a MAC CE) to transmit two power margins for a cell (e.g., if the UE is provided with twoPHR mode), (and is configured / provided with a second SRS resource set and / or a second power control parameter set and / or two power control parameter sets for PUSCH), (and the indicated TCI state and UL TCI state are associated with the second power control parameter set and / or associated with the two power control parameter sets for PUSCH), the UE (in the reference time slot) (in a MAC CE) provides / transmits two (Type 1) PHRs for the cell: including a first power margin and a second power margin.

[0267] For example, if the UE, cell, or MAC entity is configured (simultaneously / in one MAC CE) to transmit two power margins for a cell (e.g., if the UE is provided with twoPHR mode), and if a second SRS resource set and / or a second power control parameter set and / or two power control parameter sets for the PUSCH are not configured / provided, the UE (in the reference slot) (in one MAC CE) provides / transmits one (Type 1) PHR for the cell: including the power margin (first power margin or second power margin) associated with the power control parameter set associated with the indicated TCI state and UL TCI state.

[0268] For example, if a UE or cell or MAC entity is configured (simultaneously / in a MAC CE) to transmit two power margins for a cell (e.g., if the UE is provided with twoPHR mode), and is configured / provided with a second SRS resource set and / or a second power control parameter set and / or two power control parameter sets for PUSCH, if the indicated TCI state and UL TCI state are not associated with the second power control parameter set and / or only one power control parameter set associated with PUSCH, the UE (in the reference slot) (in a MAC CE) provides / transmits one (Type 1) PHR for the cell: including the power margin (first power margin or second power margin) associated with the power control parameter set associated with the indicated TCI state and UL TCI state.

[0269] For example, if the UE, cell, or MAC entity is not configured (simultaneously / in a MAC CE) to transmit two power margins for a cell (e.g., if the UE is not provided with twoPHR mode), (and is configured / provided with a second SRS resource set and / or a second power control parameter set and / or two power control parameter sets for the PUSCH), (and the indicated TCI state and UL TCI state are associated with the second power control parameter set and / or associated with the two power control parameter sets for the PUSCH), the UE (in the reference time slot) (in a MAC CE) provides / transmits one (Type 1) PHR for the serving cell: including either a first power margin or a second power margin. For example, whether to transmit the first or second power margin is predefined, i.e., the first power margin is transmitted by default, or the second power margin is transmitted by default.

[0270] For example, the transmission of a first power margin or a second power margin is determined based on a reference timeslot. For instance, if there is at least one actual PUSCH transmission in the reference timeslot, a power margin determined based on a specific (e.g., the first / last) actual PUSCH transmission is transmitted. This power margin is the first power margin determined based on that specific (e.g., the first / last) actual PUSCH transmission if that specific actual PUSCH transmission is associated with a first set of power control parameters; otherwise, it is the second power margin determined based on that specific (e.g., the first / last) actual PUSCH transmission. Otherwise (if there is no actual PUSCH transmission in the reference timeslot), the transmission of either the first or second power margin is predefined; for example, the first power margin determined based on the reference PUSCH transmission is transmitted by default, or the second power margin determined based on the reference PUSCH transmission is transmitted by default.

[0271] In some embodiments, the terminal device may be an SBFD-aware device; however, this application is not limited thereto. For example, during the initial access procedure (from RRC_IDLE to RRC_Connected state, including CBRA) and / or the random access procedure (e.g., CBRA) and / or the RRCSetupComplete message and / or in the capability information, the terminal device indicates to the network device that the terminal device is an SBFD-aware device (SBFD-aware UE).

[0272] For example, during random access, the terminal device is indicated to be an SBFD-aware device via the RO / PRACH and / or Msg3 used to send the preamble. For instance, some ROs (first ROs) are not limited to use by SBFD-aware UEs (other UEs can also use them), while some ROs (second ROs) are limited to use by SBFD-aware devices. Therefore, when a UE uses a second RO to send the preamble / PRACH, the base station knows that the UE is an SBFD-aware device (and consequently, the subsequent Msg3 and / or RRCSetupComplete message and / or capability information may include / not include information indicating that the UE is an SBFD-aware device). For example, (when the UE uses a first RO to send the preamble / PRACH), the Msg3 and / or RRCSetupComplete message and / or capability information include information indicating that the UE is an SBFD-aware device.

[0273] For example, an SBFD-aware UE has capabilities related to SBFD operation, including one or more of the following: being able to know the SBFD configuration, such as the configuration of the first time domain resources and / or the second time domain resources and / or the first frequency domain resources and / or the second frequency domain resources described below; being able to configure transmit and receive signals according to the SBFD; and being able to transmit uplink signals on (DL)SBFD symbols.

[0274] In some embodiments, for a specific terminal device, such as an SBFD-aware UE that supports independent (uplink) power control for a first time domain resource (non-SBFD) and a second time domain resource (SBFD), it is mandatory to support the simultaneous transmission of the two power margins.

[0275] In some embodiments, the specific terminal device indicates support for the independent (uplink) power control via a (same) information field (in the capability message / information), and / or indicates support for simultaneously transmitting two power margins, and / or indicates support for SBFD operation.

[0276] In some embodiments, if a (specific) terminal device supports the simultaneous transmission of the two power margins, the terminal device sends information indicating support for the simultaneous transmission of the first power margin and the second power margin.

[0277] In some embodiments, the terminal device does not send information indicating support for simultaneously sending the first power margin and the second power margin, and it is assumed that it does not support this.

[0278] In some embodiments, if a (specific) terminal device does not support simultaneously transmitting the first power margin and the second power margin, the terminal device sends information indicating that it does not support simultaneously transmitting the first power margin and the second power margin.

[0279] In some embodiments, the terminal device does not send information indicating that it does not support sending the first power margin and the second power margin simultaneously, but assumes that it does.

[0280] The above description only covers the steps or processes relevant to this application, but this application is not limited thereto. The methods in the embodiments of this application may also include other steps or processes, and for details of these steps or processes, please refer to related technologies.

[0281] The above embodiments are merely illustrative examples of embodiments of this application, but this application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0282] As can be seen from the above embodiments, when different power control parameters should be used for different time domain resources, the serving cell configuration includes at least one uplink power control information element. This uplink power control information element can include two sets of power control parameters for PUSCH / PUCCH / SRS. Then, the terminal device sends the power margin associated with the power control parameter set, thereby enabling the configuration of power control parameters for different time domain resources and the corresponding power margin report when there are different time domain resources that should use different power control parameters.

[0283] Second aspect of the embodiments

[0284] This application provides a method for receiving power margin reports, which will be described from the perspective of the network device. The content that is the same as that in the first aspect of the embodiment will not be repeated.
