Description

Methods and devices for determining power control parameters Technical Field

[0001] The embodiments of this application relate to the field of communication technology. Background Technology

[0002] In Rel-19 (Version 19), Subband Non-Overlapping Full Duplex (SBFD) will be formally standardized as a Work Item (WI). With SBFD, terminal devices can be configured with non-overlapping downlink and uplink subbands within existing downlink symbols (or time slots) or flexible symbols (or time slots), thus making that symbol (or time slot) an SBFD symbol (or time slot). Within an SBFD symbol, the terminal device can transmit uplink information on the uplink subband, or receive downlink information on the downlink subband; that is, the terminal device operates in half-duplex mode (receiving or transmitting only at the same time), while the network device can operate in full-duplex mode (receiving and transmitting simultaneously). Through SBFD, terminal devices can perform uplink transmission within existing downlink symbols or flexible symbols, effectively increasing the time-frequency resources available for uplink transmission, thereby improving uplink capacity and coverage, and reducing uplink latency.

[0003] 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

[0004] The inventors discovered that, within a unified transmission configuration indication (TCI) state framework, once a terminal device begins applying the TCI state, its uplink transmissions (including the Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), and Sound Reference Signal (SRS)) utilize power control parameters (including at least one of the target received power, path loss compensation factor, and closed-loop power control state index) from the TCI state IE. In SBFD scenarios, a TCI state IE can include two sets of power control parameters, one for uplink transmissions on non-SBFD symbols and the other for uplink transmissions on SBFD symbols. However, the terminal device can also perform uplink transmissions before applying the TCI state. In this case, determining the appropriate power control parameters for uplink transmissions on non-SBFD symbols and SBFD symbols is a problem that needs to be solved.

[0005] To address at least one of the above-mentioned problems or other similar issues, embodiments of this application provide a method and apparatus for determining power control parameters to determine power control parameters for uplink transmissions on non-SBFD symbols and on SBFD symbols before applying TCI state.

[0012] According to another aspect of the embodiments of this application, a method for determining power control parameters is provided, which is applied to a terminal device, wherein the method includes:

[0013] Send PUCCH on non-SBFD symbols and / or SBFD symbols before applying the TCI state;

[0014] The target received power is determined for PUCCH transmitted on non-SBFD symbols based on the eleventh parameter p0-nominal and / or the twelfth parameter p0-PUCCH-Value; the target received power is determined for PUCCH transmitted on SBFD symbols based on the thirteenth parameter p0-nominal-SBFD and / or the fourteenth parameter p0-PUCCH-Value-SBFD; and / or, the closed-loop power control state index is determined for PUCCH transmitted on non-SBFD symbols based on the fifteenth parameter l2; and the closed-loop power control state index is determined for PUCCH transmitted on SBFD symbols based on the sixteenth parameter l3.

[0018] According to another aspect of the embodiments of this application, a method for determining power control parameters is provided, which is applied to a terminal device, wherein the method includes:

[0019] Send SRS on non-SBFD symbols and / or SBFD symbols before applying the TCI state;

[0024] One of the beneficial effects of this application's embodiments is that, for the two types of uplink transmissions—on non-SBFD symbols and on SBFD symbols—conducted before the application of the TCI state, the terminal device does not use the two sets of power control parameters included in the TCI state, but instead uses the two sets of power control parameters configured by the SIB message or RRC signaling. Therefore, even before applying the TCI state, the terminal device can use appropriate power control parameters for uplink transmissions in different interference environments for non-SBFD symbols and SBFD symbols, which helps ensure the reliability of uplink transmissions and avoids interference to other devices.

[0053] The following examples illustrate the scenarios of embodiments of this application, but this application is not limited thereto.

[0054] Figure 1 is a schematic diagram of a communication system according to an embodiment of this application, illustrating the case of a terminal device and a network device as examples. As shown in Figure 1, the communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, Figure 1 only illustrates the case of two terminal devices and one network device, but the embodiments of this application are not limited to this.

[0055] In this embodiment of the application, network device 101 and terminal devices 102 and 103 can transmit existing services or services that can be implemented in the future. For example, these services may include, but are not limited to: enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0056] It is worth noting that Figure 1 shows that both terminal devices 102 and 103 are within the coverage area of ​​network device 101, but this application is not limited to this. Both terminal devices 102 and 103 may be outside the coverage area of ​​network device 101, or one terminal device 102 may be within the coverage area of ​​network device 101 while the other terminal device 103 may be outside the coverage area of ​​network device 101.

[0057] Figure 2 is a schematic diagram of time-frequency domain resources configured with SBFD subbands. As shown in Figure 2, the terminal device is configured with SBFD subbands. SBFD subbands include downlink subbands and uplink subbands; for example, the uplink subband is located between two downlink subbands in the frequency domain. The symbol containing the SBFD subband is called an SBFD symbol, and other symbols are called non-SBFD symbols. In the example of Figure 2, a time slot may include only SBFD symbols (SBFD time slot) or only non-SBFD symbols (non-SBFD time slot), or it may include both SBFD and non-SBFD symbols, etc. By configuring SBFD subbands in some symbols, some additional symbols can be used for uplink transmission, thereby enhancing uplink coverage, increasing uplink capacity, and reducing uplink transmission latency.

[0058] In the embodiments of this application, "SBFD symbol" can be replaced with "SBFD time slot", and "non-SBFD symbol" can be replaced with "non-SBFD time slot".

[0059] In this embodiment, the terminal device receives configuration information from the network device. This configuration information is used to configure the time-domain and / or frequency-domain positions of the SBFD sub-band. Therefore, the terminal device can determine which symbols are SBFD symbols and which are non-SBFD symbols based on the configuration information.

[0060] The interference environments of SBFD symbols and non-SBFD symbols are different. For example, inter-subband interference (ISI) exists within SBFD symbols, where downlink subbands leak into uplink subbands, and vice versa. In contrast, such ISI does not exist within non-SBFD symbols. Therefore, transmission on SBFD symbols and transmission on non-SBFD symbols require independent power control. Uplink transmission on both non-SBFD and SBFD symbols can have its transmit power determined according to the following formula, where the power control parameters used to determine the transmit power can be independent.

[0061] Specifically, the terminal device uses the parameter set with index j and the closed-loop power control state with index l to transmit PUSCH on the active uplink BWP (Bandwidth Part) b of the carrier f of the serving cell c, and the PUSCH transmission power P at PUSCH transmission occasion i. PUSCH,b,f,c (i,j,q d ,l) can be determined according to formula (1).

[0062] Among them, P CMAX,f,c (i) represents the maximum transmit power; PO_PUSCH,b,f,c (j)=P O_NOMINAL,PUSCH,f,c (j)+P O_UE_PUSCH,b,f,c (j) represents the power target value (i.e., the target received power), where P O_NOMINAL,PUSCH,f,c (j) represents the cell-specific target received power, P O_UE_PUSCH,b,f,c (j) represents the UE-specific target received power; α b,f,c (j) represents the road loss compensation factor; PL b,f,c (q d ) represents the road loss value, q d Indicates the index of the path loss reference signal; f b,f,c (i,l) represents the closed-loop power control adjustment state, where l represents the index of the closed-loop power control state, which can also be called the power control adjustment state; Δ TF,b,f,c (i) represents the power offset determined by the MCS (Modulation and Coding Scheme); This indicates the number of Resource Blocks (RBs) occupied by PUSCH.

[0063] Furthermore, the terminal device uses the closed-loop power control state with index l to transmit PUCCH on the active uplink BWP b of carrier f in serving cell c, and the PUCCH transmission power P at PUCCH transmission opportunity i. PUCCH,b,f,c (i,q u ,q d ,l) can be determined according to formula (2).

[0064] Among them, P CMAX,f,c (i) represents the maximum transmit power; P O_PUCCH,b,f,c (q u ) = P O_NOMINAL,PUCCH +P O_UE_PUCCH (q u ) represents the target power value, where P O_NOMINAL,PUCCH P represents the target received power specific to the cell. O_UE_PUCCH (q u ) represents the UE-specific target received power; PL b,f,c (q d ) represents the road loss value, q d Indicates the index of the path loss reference signal; g b,f,c (i,l) represents the closed-loop power control adjustment state, and l represents the index of the closed-loop power control state; Δ F_PUCCH (F) and Δ TF,b,f,c (i) indicates the power offset associated with the PUCCH format; This indicates the number of RBs occupied by PUCCH.

[0065] Additionally, the terminal device uses the closed-loop power control state with index l to transmit SRS on the active uplink BWP b of carrier f in serving cell c, and the SRS transmission power P at SRS transmission opportunity i. SRS,b,f,c (i,q s ,l) can be determined according to formula (3).

[0066] Among them, P CMAX,f,c (i) represents the maximum transmit power; P O_SRS,b,f,c (q s ) represents the target power value; α SRS,b,f,c (q s ) represents the road loss compensation factor; PL b,f,c (q d ) represents the road loss value, q d Indicates the index of the path loss reference signal; h b,f,c (i,l) represents the closed-loop power control adjustment state, and l represents the index of the closed-loop power control state; M SRS,b,f,c (i) represents the number of RBs occupied by SRS.

[0067] Rel-17 standardizes the unified transmission configuration indication (TCI) state. The Rel-17 unified TCI state is designed for sTRP scenarios, where the TCI field of DCI format 1_1 or DCI format 1_2 indicates one or more TCI states. DCI format 1_1 or DCI format 1_2 can schedule downlink data (referred to as DCI format 1_1 / 1_2 with DL assignment) or not schedule downlink data (referred to as DCI format 1_1 / 1_2 without DL assignment).

[0068] The indication or update of the TCI state includes the indication or update of the beam used by the terminal equipment. For the unified TCI state, the higher-layer parameter "unifiedTCI-StateType" can be configured to use a joint TCI state or a separate TCI state. When the "unifiedTCI-StateType" parameter is set to 'joint', the TCI state is a joint TCI state; when the "unifiedTCI-StateType" parameter is set to 'separate', the TCI state is a downlink TCI state and / or an uplink TCI state. The uplink beam is also called the uplink transmit spatial filter. For Rel-17 unified TCI, a TCI field indicates a joint TCI state, or indicates a downlink TCI state, or indicates an uplink TCI state, or indicates a downlink TCI state and an uplink TCI state. If a cell is configured with unifiedTCI-StateType, the cell uses the unified TCI state.

[0069] Furthermore, the indication or update of the TCI state also includes the indication or update of the power control parameters used by the terminal equipment. For a unified TCI state, the TCI state IE includes power control parameters (including at least one of the target received power, path loss compensation factor, and closed-loop power control state index). For uplink transmission, the terminal equipment also applies the power control parameters in the TCI state when applying the TCI state.

[0070] Figure 3 illustrates the application of TCI state by a terminal device within the unified TCI state framework. As shown in Figure 3, the terminal device receives DCI 1 indicating TCI state 1 and sends ACK 1 to the network device. The terminal device begins applying TCI state 1 at a certain time t1 after ACK 1. Subsequently, the terminal device receives DCI 2 indicating TCI state 2 (TCI state 2 is different from TCI state 1) and sends ACK 2 to the network device. The terminal device begins applying TCI state 2 at a certain time t2 after ACK 2. Therefore, the terminal device applies TCI state 1 during the time period from t1 to t2, and applies the two sets of power control parameters from TCI state 1 to uplink transmissions on non-SBFD symbols and SBFD symbols respectively during this time period. Similarly, the terminal device applies TCI state 2 during the time period from t2 to t3, and applies the two sets of power control parameters from TCI state 2 to uplink transmissions on non-SBFD symbols and SBFD symbols respectively during this time period, and so on. Once the terminal device begins applying the TCI state, it can use the power control parameters within the TCI state. However, for uplink transmissions prior to t1, the terminal device cannot apply any power control parameters from the TCI state. Therefore, determining the appropriate power control parameters for uplink transmissions on non-SBFD symbols and those on SBFD symbols is a problem that needs to be solved.

[0071] In the embodiments of this application, the signaling may be, for example, Radio Resource Control (RRC) signaling; for example, referred to as an RRC message, including MIB, system information, dedicated RRC messages; or referred to as an RRC information element. The signaling may also be, for example, Medium Access Control (MAC) signaling; or referred to as a MAC control element. However, this application is not limited to these.

[0072] Furthermore, in this embodiment, the parameters, modules, or components shown in the figures are not limited to appearing simultaneously; the presence of only some parameters, modules, or components is also permitted. For power control parameters not covered in this embodiment, this embodiment does not restrict how their values ​​are determined; for example, they can be determined based on existing technology.

[0073] In the following description, without causing confusion, the terms "PUSCH" and "Physical Uplink Data Channel," "Physical Uplink Shared Channel," or "Uplink Data" are used interchangeably. Furthermore, sending or receiving a PUSCH can be understood as sending or receiving uplink data carried by the PUSCH. Additionally, expressions such as "when," "if," and "under certain circumstances" have the same meaning and are used interchangeably.

[0074] This application uses the example of a terminal device using a unified TCI state for illustration, but the application is not limited thereto.

[0075] The embodiments of this application will now be described with reference to the accompanying drawings.

[0076] First aspect of the embodiments

[0077] This application provides a method for determining power control parameters, which is applied to a terminal device. Figure 4 is a schematic diagram of the method for determining power control parameters according to an embodiment of this application. As shown in Figure 4, the method includes:

[0078] 401. Before the application Transmission Configuration Indication (TCI) state, the terminal device transmits the Physical Uplink Shared Channel (PUSCH) on non-subband full-duplex (SBFD) symbols and / or SBFD symbols.

[0079] 402, the terminal device determines the target received power for PUSCH transmitted on non-SBFD symbols based on at least one of the first parameter preambleReceivedTargetPower, the second parameter msg3-DeltaPreamble, and the third parameter deltaPreamble; and determines the target received power for PUSCH transmitted on SBFD symbols based on at least one of the fourth parameter preambleReceivedTargetPower-SBFD, the fifth parameter msg3-DeltaPreamble-SBFD, and the sixth parameter deltaPreamble-SBFD; and / or, the terminal device determines the path loss compensation factor for PUSCH transmitted on non-SBFD symbols based on the seventh parameter msg3-Alpha; and determines the path loss compensation factor for PUSCH transmitted on SBFD symbols based on the eighth parameter msg3-Alpha-SBFD.

[0080] It is worth noting that Figure 4 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 4 above.

[0081] According to the above embodiments, for the two types of uplink transmissions (PUSCH transmitted on non-SBFD symbols and SBFD symbols) performed before the application of the TCI state, the terminal device does not use the two sets of power control parameters included in the TCI state, but instead uses the two sets of configured power control parameters. Therefore, even before applying the TCI state, the terminal device can use appropriate power control parameters for uplink transmission in different interference environments for non-SBFD symbols and SBFD symbols, which helps ensure the reliability of uplink transmission and avoids interference to other devices.

[0082] For example, under the unified TCI state framework, the power control parameters are determined by the indicated TCI state, that is, the power control parameters are included in the TCI state IE. However, the terminal device cannot use the power control parameters in the TCI state IE before the terminal device applies the indicated TCI state. Therefore, the terminal device needs to obtain the power control parameters through other means besides the TCI state so that it can perform uplink transmission before applying the TCI state.

[0083] In the example above, the terminal device can still transmit PUSCH before applying the TCI state. PUSCH can be located only on non-SBFD symbols, only on SBFD symbols, or across both non-SBFD and SBFD symbols. For example, PUSCH spans multiple time slots, located on non-SBFD symbols in some time slots and on SBFD symbols in others. The terminal device determines independent power control parameters for PUSCH transmitted on non-SBFD symbols and PUSCH transmitted on SBFD symbols, including target received power and / or path loss compensation factor.

[0084] The target received power is denoted as P. O_PUSCH,b,f,c (j), P O_PUSCH,b,f,c (j)=P O_NOMINAL,PUSCH,f,c (j)+P O_UE_PUSCH,b,f,c (j), where P O_NOMINAL,PUSCH,f,c (j)=P O_PRE +Δ PREAMBLE,Msg3 The road loss compensation factor is denoted as α. b,f,c (j).

[0085] For the above parameter P O_PRE For example, for a PUSCH transmitted on a non-SBFD symbol, P O_PRE Configured by preambleReceivedTargetPower, for PUSCH sent on SBFD symbols, P O_PREConfigured by preambleReceivedTargetPower-SBFD.

[0086] For the above parameter Δ PREAMBLE,Msg3 For example, for a PUSCH transmitted on a non-SBFD symbol, Δ PREAMBLE,Msg3 Configured by msg3-DeltaPreamble or deltaPreamble, for PUSCH sent on SBFD symbols, Δ PREAMBLE,Msg3 Configured by msg3-DeltaPreamble-SBFD or deltaPreamble-SBFD.

[0087] For the above parameter P O_UE_PUSCH,b,f,c (j), for example, for PUSCH transmitted on non-SBFD symbols and on SBFD symbols, P O_UE_PUSCH,b,f,c (j) = 0. That is, regardless of whether it is a non-SBFD symbol or an SBFD symbol, P O_UE_PUSCH,b,f,c (j) takes the value 0.

[0088] For the above parameter α b,f,c (j), for example, for a PUSCH transmitted on a non-SBFD symbol, α b,f,c (j) Configured by msg3-Alpha, for PUSCH transmitted on SBFD symbols, α b,f,c (j) Configured by msg3-Alpha-SBFD.

[0089] In some possible implementations, for example, for PUSCH transmitted on a non-SBFD symbol, P O_PRE Configured by preambleReceivedTargetPower, Δ PREAMBLE,Msg3 Configured by msg3-DeltaPreamble or deltaPreamble, α b,f,c (j) Configured by msg3-Alpha; for PUSCH transmitted on SBFD symbols, P O_PRE Δ PREAMBLE,Msg3 and α b,f,c At least one of the parameters in (j) is configured differently from the parameters of the PUSCH transmitted on a non-SBFD symbol, and the rest are configured with the same parameters as the PUSCH transmitted on a non-SBFD symbol. For example, for the PUSCH transmitted on an SBFD symbol, P O_PRE Configured by preambleReceivedTargetPower-SBFD, Δ PREAMBLE,Msg3 Configured by msg3-DeltaPreamble-SBFD or deltaPreamble-SBFD, α b,f,c(j) Configured by msg3-Alpha.

[0090] In the above embodiments, it is assumed that the terminal device establishes an RRC connection through Type-1 random access (i.e., four-step random access). This application is not limited to this. The method of the above embodiments can be extended to the case where the terminal device establishes an RRC connection through Type-2 random access (i.e., two-step random access). In this case, some of the parameters mentioned above can be replaced with parameters related to two-step random access. For example, preambleReceivedTargetPower can be replaced with msgA-preambleReceivedTargetPower, msg3-DeltaPreamble can be replaced with msgA-DeltaPreamble, Δ PREAMBLE,Msg3 It can be replaced with Δ MsgA_PUSCH msg3-Alpha can be replaced with msgA-Alpha, and parameters with the SBFD suffix can also be extended in the same way, which will not be elaborated here.

[0091] In some embodiments of this application, the first to eighth parameters can be configured by SIB messages or RRC signaling.

[0092] For example, preambleReceivedTargetPower is configured by System Information Block (SIB) messages or Radio Resource Control (RRC) signaling; preambleReceivedTargetPower-SBFD is configured by SIB messages or RRC signaling, or preambleReceivedTargetPower-SBFD is the sum of preambleReceivedTargetPower and offset0, where offset0 can also be configured by SIB messages or RRC signaling.

[0093] For example, msg3-DeltaPreamble is configured by SIB messages or RRC signaling; msg3-DeltaPreamble-SBFD is configured by SIB messages or RRC signaling, or msg3-DeltaPreamble-SBFD is the sum of msg3-DeltaPreamble and offset1, where offset1 can also be configured by SIB messages or RRC signaling.

[0094] For example, deltaPreamble is configured by SIB messages or RRC signaling; deltaPreamble-SBFD is configured by SIB messages or RRC signaling, or deltaPreamble-SBFD is the sum of deltaPreamble and offset2, where offset2 can also be configured by SIB messages or RRC signaling;

[0095] For example, msg3-Alpha is configured by SIB messages or RRC signaling; msg3-Alpha-SBFD is configured by SIB messages or RRC signaling, or msg3-Alpha-SBFD is the sum of msg3-Alpha and offset3, where offset3 can also be configured by SIB messages or RRC signaling.

[0096] For the first and fourth parameters, in some possible implementations, `preambleReceivedTargetPower` and `preambleReceivedTargetPower-SBFD` can be configured in `RACH-ConfigGeneric`. `RACH-ConfigGeneric` can be configured via SIB1 messages or dedicated RRC signaling, and can be configured per BWP. For example, some BWPs have an SBFD subband, while others do not. For BWPs without an SBFD subband, `preambleReceivedTargetPower-SBFD` does not need to be configured. Similarly, this can be extended to other parameters with `SBFD` as a suffix. For example, `preambleReceivedTargetPower-SBFD` is cell-specific, and its value is the same within a single cell.

[0097] Below is an example of RACH-ConfigGeneric:

[0098] In some other possible implementations, preambleReceivedTargetPower and offset0 can be configured in RACH-ConfigGeneric, where preambleReceivedTargetPower-SBFD is the sum of preambleReceivedTargetPower and offset0.

[0099] For the second and fifth parameters, in some possible implementations, msg3-DeltaPreamble and msg3-DeltaPreamble-SBFD can be configured in PUSCH-ConfigCommon. PUSCH-ConfigCommon can be configured via SIB1 messages or dedicated RRC signaling, and can be configured per BWP. For example, msg3-DeltaPreamble-SBFD is cell-specific, and its value is the same within a cell.

[0100] Below is an example of PUSCH-ConfigCommon:

[0101] In some other possible implementations, msg3-DeltaPreamble and offset1 can be configured in PUSCH-ConfigCommon, where msg3-DeltaPreamble-SBFD is the sum of msg3-DeltaPreamble and offset1.

[0102] For the third and sixth parameters, in some possible implementations, deltaPreamble and deltaPreamble-SBFD can be configured in FeatureCombinationPreambles. FeatureCombinationPreambles can be configured via SIB1 messages or dedicated RRC signaling, and can be configured per BWP. For example, deltaPreamble-SBFD is cell-specific, and its value is the same within a cell.

[0103] Below is an example of FeatureCombinationPreambles:

[0104] In some other possible implementations, deltaPreamble and offset2 are configured in FeatureCombinationPreambles, where deltaPreamble-SBFD is the sum of deltaPreamble and offset2.

[0105] For the seventh and eighth parameters, in some possible implementations, msg3-Alpha and msg3-Alpha-SBFD can be configured in PUSCH-PowerControl. PUSCH-PowerControl can be configured via dedicated RRC signaling, and can be configured per BWP.

[0106] Below is an example of PUSCH-PowerControl:

[0107] In some other possible implementations, msg3-Alpha and offset3 can be configured in PUSCH-PowerControl, where msg3-Alpha-SBFD is the sum of msg3-Alpha and offset3.

[0108] In some embodiments of this application, if preambleReceivedTargetPower-SBFD does not exist, the terminal device determines the target received power based on the PUSCH transmitted on the SBFD symbol according to preambleReceivedTargetPower; and / or, if deltaPreamble-SBFD does not exist and msg3-DeltaPreamble-SBFD does not exist, the terminal device determines the target received power based on deltaPreamble or msg3-DeltaPreamble for the PUSCH transmitted on the SBFD symbol; and / or, if msg3-Alpha-SBFD does not exist, the terminal device determines the path loss compensation factor based on msg3-Alpha for the PUSCH transmitted on the SBFD symbol.

[0109] For example, for a PUSCH transmitted on an SBFD symbol, if preambleReceivedTargetPower-SBFD exists, the end device uses preambleReceivedTargetPower-SBFD to determine the PUSCH signal. O_PRE If preambleReceivedTargetPower-SBFD does not exist (e.g., preambleReceivedTargetPower-SBFD is not configured, or offset0 is not configured), the terminal device uses preambleReceivedTargetPower, or the terminal device considers P... O_PRE=0. For example, if the terminal device uses preambleReceivedTargetPower for PUSCH transmitted on SBFD symbols, and preambleReceivedTargetPower does not exist, then P... O_PRE =0. In the embodiments of this application, "does not exist" can also be replaced with "not configured".

[0110] For example, for a PUSCH transmitted on a non-SBFD symbol, if deltaPreamble exists, the terminal device uses deltaPreamble (e.g., to determine Δ) PREAMBLE,Msg3 If deltaPreamble does not exist but msg3-DeltaPreamble exists, the terminal device uses msg3-DeltaPreamble; if neither deltaPreamble nor msg3-DeltaPreamble exists, then Δ... PREAMBLE,Msg3 =0, meaning the default value of 0 is used.

[0111] For example, for a PUSCH transmitted on an SBFD symbol, if deltaPreamble-SBFD exists, the terminal device uses deltaPreamble-SBFD and ignores msg3-DeltaPreamble-SBFD; if deltaPreamble-SBFD does not exist but msg3-DeltaPreamble-SBFD exists, the terminal device uses msg3-DeltaPreamble-SBFD; if neither deltaPreamble-SBFD nor msg3-DeltaPreamble-SBFD exists, then Δ... PREAMBLE,Msg3 =0, or the terminal device uses deltaPreamble or msg3-DeltaPreamble. For example, when the terminal device uses deltaPreamble or msg3-DeltaPreamble for PUSCH transmitted on SBFD symbols, the order of use is the same as when the terminal device uses deltaPreamble or msg3-DeltaPreamble for PUSCH transmitted on non-SBFD symbols, as described above.

[0112] For example, for a PUSCH transmitted on an SBFD symbol, if msg3-DeltaPreamble-SBFD exists, the terminal device uses msg3-DeltaPreamble-SBFD; if msg3-DeltaPreamble-SBFD does not exist, then ΔPREAMBLE,Msg3 =0, or the terminal device uses msg3-DeltaPreamble. For example, when the terminal device uses msg3-DeltaPreamble for PUSCH transmitted on SBFD symbols, if msg3-DeltaPreamble does not exist, then Δ PREAMBLE,Msg3 =0.

[0113] For example, for a PUSCH sent on a non-SBFD symbol, if msg3-Alpha does not exist, then α b,f,c (j) = 1.

[0114] For example, for a PUSCH transmitted on an SBFD symbol, if msg3-Alpha-SBFD exists, the terminal device uses msg3-Alpha-SBFD (e.g., to determine α) b,f,c (j)); If msg3-Alpha-SBFD does not exist, then α b,f,c (j) = 1, or the terminal device uses msg3-Alpha; if msg3-Alpha does not exist, then α b,f,c (j) = 1.

[0115] In some embodiments of this application, the PUSCH is either a first PUSCH or a second PUSCH, wherein the first PUSCH is Msg3, and the second PUSCH is any PUSCH other than Msg3. For the definition of Msg3, please refer to related technologies.

[0116] For example, before applying the TCI state, the PUSCH sent by the terminal device can be divided into a first PUSCH and a second PUSCH, where the first PUSCH is Msg3 and the second PUSCH is any PUSCH other than Msg3.

[0117] In the above embodiments, it is assumed that the terminal device establishes an RRC connection through Type-1 random access. This application is not limited to this, and the method of the above embodiments can be extended to the case where the terminal device establishes an RRC connection through Type-2 random access. In this case, the first PUSCH is MsgA PUSCH, and the second PUSCH is a PUSCH other than MsgA PUSCH. For the definition of MsgA, please refer to related technologies.

[0118] In the above embodiments, in some possible implementations, the terminal device can determine the target received power based on the same set of parameters for the first PUSCH and the second PUSCH transmitted on non-SBFD symbols, and determine the target received power based on the same set of parameters for the first PUSCH and the second PUSCH transmitted on SBFD symbols; and / or, the terminal device can determine the path loss compensation factor based on the same set of parameters for the first PUSCH and the second PUSCH transmitted on non-SBFD symbols, and determine the path loss compensation factor based on the same set of parameters for the first PUSCH and the second PUSCH transmitted on SBFD symbols.

[0119] For example, within a BWP, if the first PUSCH is Msg3 and the second PUSCH is a PUSCH other than Msg3, the terminal device determines the target receive power for the first and second PUSCHs transmitted on non-SBFD symbols based on at least one of preambleReceivedTargetPower, msg3-DeltaPreamble, and deltaPreamble, and determines the target receive power for the first and second PUSCHs transmitted on SBFD symbols based on at least one of preambleReceivedTargetPower-SBFD, msg3-DeltaPreamble-SBFD, and deltaPreamble-SBFD; and / or, the terminal device determines the path loss compensation factor for the first and second PUSCHs transmitted on non-SBFD symbols based on msg3-Alpha, and determines the path loss compensation factor for the first and second PUSCHs transmitted on SBFD symbols based on msg3-Alpha-SBFD.

[0120] Figure 5 is a schematic diagram of determining power control parameters for PUSCH according to an embodiment of this application.

[0121] As shown in Figure 5, within a BWP, for the second PUSCH on a non-SBFD symbol, the terminal device uses the same PUSCH as the first PUSCH on a non-SBFD symbol. O_NOMINAL,PUSCH,f,c (j)(P0-nominal); For the second PUSCH on the SBFD symbol, the terminal device uses the same P for it as for the first PUSCH on the SBFD symbol. O_NOMINAL,PUSCH,f,c (j). How to determine P for the first PUSCH on non-SBFD symbols and on SBFD symbols. O_NOMINAL,PUSCH,f,c (j) This application does not impose any limitations; for example, P can be determined by any of the methods described above. O_NOMINAL,PUSCH,f,c (j).

[0122] Furthermore, for both the second and first PUSCH on non-SBFD symbols and on SBFD symbols, P... O_UE_PUSCH,b,f,c (j) = 0 (P0-UE is 0).

[0123] Additionally, for the second PUSCH on a non-SBFD symbol, the terminal device uses the same α as for the first PUSCH on a non-SBFD symbol. b,f,c (j)(alpha); For the second PUSCH on the SBFD symbol, the terminal device uses the same alpha as for the first PUSCH on the SBFD symbol. b,f,c (j). How to determine α for the first PUSCH on non-SBFD symbols and on SBFD symbols. b,f,c (j) This application does not impose any limitations; for example, α can be determined by any of the methods described above. b,f,c (j).

[0124] In some embodiments of this application, the terminal device determines the closed-loop power control status index for PUSCH transmitted on non-SBFD symbols based on the ninth parameter l0, and determines the closed-loop power control status index for PUSCH transmitted on SBFD symbols based on the tenth parameter l1.

[0125] For example, power control parameters also include a closed-loop power control state index l, with separate l used for PUSCH transmitted on non-SBFD symbols and on SBFD symbols. For f b,f,c The closed-loop power control state index l in (i,l) takes values ​​l0 and l1, which correspond to PUSCH transmitted on non-SBFD symbols and SBFD symbols, respectively.

[0126] In the example above, l0 and l1 can be configured via RRC signaling, for example, configured as (l0=0, l1=1) or (l0=1, l1=0); or, l0 and l1 can be predefined, for example, predefined as (l0=0, l1=1) or (l0=1, l1=0).

[0127] In the above embodiments, the determination of power control parameters for PUSCH transmitted on non-SBFD symbols and SBFD symbols has been described. The following will describe the determination of power control parameters for PUCCH and SRS transmitted on non-SBFD symbols and SBFD symbols respectively.

[0128] Figure 6 is another schematic diagram of the method for determining power control parameters according to an embodiment of this application. As shown in Figure 6, the method further includes:

[0129] 601. Transmit the Physical Uplink Control Channel (PUCCH) on non-SBFD symbols and / or SBFD symbols before applying the TCI state;

[0130] 602, determine the target receive power for PUCCH transmitted on non-SBFD symbols based on the eleventh parameter p0-nominal and / or the twelfth parameter p0-PUCCH-Value, and determine the target receive power for PUCCH transmitted on SBFD symbols based on the thirteenth parameter p0-nominal-SBFD and / or the fourteenth parameter p0-PUCCH-Value-SBFD.

[0131] 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.

[0132] According to the above embodiments, for the two types of uplink transmissions (PUCCHs transmitted on non-SBFD symbols and SBFD symbols) performed before the application of the TCI state, the terminal device does not use the two sets of power control parameters included in the TCI state, but instead uses the two sets of configured power control parameters. Therefore, even before applying the TCI state, the terminal device can use appropriate power control parameters for uplink transmission in different interference environments for non-SBFD symbols and SBFD symbols, which helps ensure the reliability of uplink transmission and avoids interference to other devices.

[0133] For example, under the unified TCI state framework, the terminal device cannot use the power control parameters in the TCI state IE before applying the TCI state indicated by the terminal device application. To transmit PUCCH, the terminal device obtains the power control parameters through methods other than the TCI state. PUCCH can reside only on non-SBFD symbols, only on SBFD symbols, or span both non-SBFD and SBFD symbols. For example, PUCCH may span multiple time slots, residing on non-SBFD symbols in some time slots and on SBFD symbols in others. The terminal device determines independent power control parameters for PUCCH transmitted on non-SBFD symbols and on SBFD symbols, respectively. These power control parameters include the target received power. The target received power is denoted as P. O_PUCCH,b,f,c (q u ), P O_PUCCH,b,f,c (q u ) = P O_NOMINAL,PUCCH +P O_UE_PUCCH (qu ).

[0134] For the above parameter P O_NOMINAL,PUCCH For example, for a PUCCH transmitted on a non-SBFD symbol, P O_NOMINAL,PUCCH Configured by p0-nominal, for PUCCH transmitted on SBFD symbols, P O_NOMINAL,PUCCH Configured by p0-nominal-SBFD.

[0135] For the above parameter P O_UE_PUCCH (q u For example, for a PUCCH transmitted on a non-SBFD symbol, P O_UE_PUCCH (q u Configured by p0-PUCCH-Value, for PUCCHs transmitted on SBFD symbols, P... O_UE_PUCCH (q u Configured by p0-PUCCH-Value-SBFD.

[0136] In some possible implementations, for example, for a PUCCH transmitted on a non-SBFD symbol, P O_NOMINAL,PUCCH Configured by p0-nominal, P O_UE_PUCCH (q u ) is configured by p0-PUCCH-Value; for PUCCHs transmitted on SBFD symbols, P O_NOMINAL,PUCCH and P O_UE_PUCCH (q u At least one of the parameters in the PUCCH is configured differently from that of a PUCCH transmitted on a non-SBFD symbol, while the rest are configured with the same parameters as a PUCCH transmitted on a non-SBFD symbol. For example, for a PUCCH transmitted on an SBFD symbol, P... O_NOMINAL,PUCCH Configured by p0-nominal-SBFD, P O_UE_PUCCH (q u Configured by p0-PUCCH-Value.

[0137] In other possible implementations, for example, for PUCCH transmitted on non-SBFD symbols, P O_NOMINAL,PUCCH Configured by p0-nominal, P O_UE_PUCCH (q u ) = 0; for PUCCH transmitted on SBFD symbols, P O_NOMINAL,PUCCH Configured by p0-nominal-SBFD, P O_UE_PUCCH (q u P = 0. That is, regardless of whether the symbol is non-SBFD or SBFD, P O_UE_PUCCH (q uThe value is 0.

[0138] In some other possible implementations, for example, for PUCCH transmitted on non-SBFD symbols, P O_NOMINAL,PUCCH Configured by p0-nominal, P O_UE_PUCCH (q u The p0-PUCCH-Value is configured by the smallest p0-PUCCH-Id associated with it; for PUCCHs transmitted on SBFD symbols, P... O_NOMINAL,PUCCH Configured by p0-nominal-SBFD, P O_UE_PUCCH (q u The p0-PUCCH-Value configuration is associated with the smallest p0-PUCCH-Id.

[0139] In some embodiments of this application, the eleventh to fourteenth parameters described above can be configured by SIB messages or RRC signaling.

[0140] For example, p0-nominal is configured by SIB messages or RRC signaling; p0-nominal-SBFD is configured by SIB messages or RRC signaling, or p0-nominal-SBFD is the sum of p0-nominal and offset4, where offset4 can also be configured by SIB messages or RRC signaling.

[0141] For example, p0-PUCCH-Value is configured by SIB messages or RRC signaling; p0-PUCCH-Value-SBFD is configured by SIB messages or RRC signaling, or p0-PUCCH-Value-SBFD is the sum of p0-PUCCH-Value and offset5, where offset5 can also be configured by SIB messages or RRC signaling.

[0142] For the eleventh and thirteenth parameters, in some possible implementations, p0-nominal and p0-nominal-SBFD can be configured in PUCCH-ConfigCommon. PUCCH-ConfigCommon can be configured via SIB1 messages or dedicated RRC signaling, and can be configured per BWP. For example, p0-nominal-SBFD is cell-specific, and its value is the same within a cell.

[0143] Below is an example of PUCCH-ConfigCommon:

[0144] In some other possible implementations, p0-nominal and offset4 can be configured in PUCCH-ConfigCommon, where p0-nominal-SBFD is the sum of p0-nominal and offset4.

[0145] For the twelfth and fourteenth parameters, in some possible implementations, p0-PUCCH-Value and p0-PUCCH-Value-SBFD can be configured in P0-PUCCH. P0-PUCCH can be configured via dedicated RRC signaling and can be configured per BWP.

[0146] Below is an example of P0-PUCCH:

[0147] In some other possible implementations, p0-PUCCH-Value and offset5 can be configured in P0-PUCCH, and p0-PUCCH-Value-SBFD is the sum of p0-PUCCH-Value and offset5.

[0148] In some other possible implementations, each P0-PUCCH is configured with a p0-PUCCH-Value, which is the p0-PUCCH-Value in the P0-PUCCH with the first P0-PUCCH-Id, and p0-PUCCH-Value-SBFD is the p0-PUCCH-Value in the P0-PUCCH with the second P0-PUCCH-Id. The P0-PUCCH can be configured via dedicated RRC signaling and can be configured per BWP.

[0149] Below is another example of P0-PUCCH:

[0150] In some embodiments of this application, p0-PUCCH-Value is associated with the smallest p0-PUCCH-Id, and p0-PUCCH-Value-SBFD is associated with the smallest p0-PUCCH-Id; or, p0-PUCCH-Value is associated with the smallest p0-PUCCH-Id, and p0-PUCCH-Value-SBFD is associated with the second smallest p0-PUCCH-Id.

[0151] For example, a terminal device can be configured with one or more P0-PUCCHs. Each P0-PUCCH is identified by a P0-PUCCH-Id. The P0-PUCCH with the smallest P0-PUCCH-Id includes a p0-PUCCH-Value and a p0-PUCCH-Value-SBFD (see the previous P0-PUCCH IE section). That is, the smallest P0-PUCCH-Id is associated with a p0-PUCCH-Value and a p0-PUCCH-Value-SBFD. The p0-PUCCH-Value is the p0-PUCCH-Value associated with the smallest P0-PUCCH-Id, and the p0-PUCCH-Value-SBFD is the p0-PUCCH-Value-SBFD associated with the smallest P0-PUCCH-Id.

[0152] For example, a terminal device can be configured with one or more P0-PUCCHs, each P0-PUCCH being identified by a P0-PUCCH-Id, and each P0-PUCCH containing only one p0-PUCCH-Value; that is, each P0-PUCCH-Id is associated with one p0-PUCCH-Value. The p0-PUCCH-Value is the p0-PUCCH-Value associated with the smallest P0-PUCCH-Id, and p0-PUCCH-Value-SBFD is the p0-PUCCH-Value associated with the second smallest P0-PUCCH-Id. Without loss of generality, "smallest P0-PUCCH-Id" can be replaced with "P0-PUCCH-Id with a first specific value," and "second smallest P0-PUCCH-Id" can be replaced with "P0-PUCCH-Id with a second specific value."

[0153] In some embodiments of this application, if p0-nominal-SBFD does not exist, the target receive power is determined based on p0-nominal for the PUCCH transmitted on the SBFD symbol; and / or, if p0-PUCCH-Value-SBFD does not exist, the target receive power is determined based on p0-PUCCH-Value for the PUCCH transmitted on the SBFD symbol.

[0154] For example, for a PUCCH transmitted on an SBFD symbol, if p0-nominal-SBFD exists, the terminal device uses p0-nominal-SBFD (e.g., to determine P) O_NOMINAL,PUCCH If p0-nominal-SBFD does not exist, for example, p0-nominal-SBFD is not configured, or offset4 is not configured, then P O_NOMINAL,PUCCH=0, or the terminal device uses p0-nominal. For example, if the terminal device uses p0-nominal for PUCCH transmitted on SBFD symbols, then if p0-nominal does not exist, then P O_NOMINAL,PUCCH =0.

[0155] For example, for a PUCCH transmitted on an SBFD symbol, if p0-PUCCH-Value-SBFD exists, the terminal device uses p0-PUCCH-Value-SBFD (for example, to determine P) O_UE_PUCCH (q u If p0-PUCCH-Value-SBFD does not exist, for example, p0-PUCCH-Value-SBFD is not configured, or offset5 is not configured, then P O_UE_PUCCH (q u ) = 0, or the terminal device uses p0-PUCCH-Value. For example, if the terminal device uses p0-PUCCH-Value for PUCCH transmitted on an SBFD symbol, and p0-PUCCH-Value does not exist, then P O_UE_PUCCH (q u ) = 0.

[0156] In some embodiments of this application, PUCCH is either a first PUCCH or a second PUCCH. The first PUCCH is a PUCCH for Msg4, and the second PUCCH is a PUCCH other than the one for Msg4. For a definition of Msg4, please refer to related technologies.

[0157] For example, before applying the TCI state, the PUCCH sent by the terminal device can be divided into a first PUCCH and a second PUCCH, where the first PUCCH is the PUCCH for Msg4 and the second PUCCH is the PUCCH other than the PUCCH for Msg4.

[0158] In the above embodiments, in some possible implementations, the terminal device can determine the target receive power based on the same set of parameters for the first PUCCH and the second PUCCH transmitted on non-SBFD symbols, and determine the target receive power based on the same set of parameters for the first PUCCH and the second PUCCH transmitted on SBFD symbols.

[0159] For example, within a BWP, if the first PUCCH is a PUCCH for Msg4 and the second PUCCH is a PUSCH other than the PUCCH for Msg4, the terminal device determines the target receive power for the first and second PUCCHs transmitted on non-SBFD symbols based on p0-nominal and / or p0-PUCCH-Value, and determines the target receive power for the first and second PUCCHs transmitted on SBFD symbols based on p0-nominal-SBFD and / or p0-PUCCH-Value-SBFD.

[0160] For example, within a BWP, for a second PUCCH on a non-SBFD symbol, the terminal device uses the same PUCCH for it as for the first PUCCH on a non-SBFD symbol. O_NOMINAL,PUCCH and / or P O_UE_PUCCH (q u For the second PUCCH on the SBFD symbol, the terminal device uses the same PUCCH for it as for the first PUCCH on the SBFD symbol. O_NOMINAL,PUCCH and / or P O_UE_PUCCH (q u ).

[0161] In some embodiments of this application, the terminal device determines the closed-loop power control state index for PUCCH transmitted on non-SBFD symbols based on the fifteenth parameter l2, and determines the closed-loop power control state index for PUCCH transmitted on SBFD symbols based on the sixteenth parameter l3.

[0162] For example, power control parameters also include a closed-loop power control state index l, with separate l used for PUCCHs transmitted on non-SBFD symbols and those transmitted on SBFD symbols. For g b,f,c The closed-loop power control state index l in (i,l) takes values ​​l2 and l3, which correspond to the PUCCH transmitted on non-SBFD symbols and SBFD symbols, respectively.

[0163] In the example above, l2 and l3 can be configured via RRC signaling, for example, configured as (l2=0, l3=1) or (l2=1, l3=0); or, l2 and l3 can be predefined, for example, predefined as (l2=0, l3=1) or (l2=1, l3=0).

[0164] In the above embodiments, the determination of power control parameters for PUSCH and PUCCH transmitted on non-SBFD symbols and SBFD symbols has been described respectively. The following will describe the determination of power control parameters for SRS transmitted on non-SBFD symbols and SBFD symbols respectively.

[0165] Figure 7 is another schematic diagram of the method for determining power control parameters according to an embodiment of this application. As shown in Figure 7, the method further includes:

[0166] 701, Transmit a sounding reference signal (SRS) on non-SBFD symbols and / or SBFD symbols before applying the TCI state;

[0167] 702, determine the target received power for SRS transmitted on non-SBFD symbols according to the seventeenth parameter p0, and determine the target received power for SRS transmitted on SBFD symbols according to the eighteenth parameter p0-SBFD; and / or, determine the path loss compensation factor for SRS transmitted on non-SBFD symbols according to the nineteenth parameter alpha, and determine the path loss compensation factor for SRS transmitted on SBFD symbols according to the twentieth parameter alpha-SBFD.

[0168] It is worth noting that Figure 7 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 7 above.

[0169] According to the above embodiments, for the two types of uplink transmissions (SRS transmitted on non-SBFD symbols and SBFD symbols) performed before the application of the TCI state, the terminal device does not use the two sets of power control parameters included in the TCI state, but instead uses the two sets of configured power control parameters. Therefore, even before applying the TCI state, the terminal device can use appropriate power control parameters for uplink transmission in different interference environments for non-SBFD symbols and SBFD symbols, which helps ensure the reliability of uplink transmission and avoids interference to other devices.

[0170] For example, under the unified TCI state framework, before the terminal device applies the indicated TCI state, it obtains the power control parameters for SRS transmission through methods other than the TCI state. Here, the SRS is the SRS applying the unified TCI state, meaning the SRS resource set to which this SRS resource resides is configured to follow UnifiedTCI-StateSRS. The SRS can reside only on non-SBFD symbols, only on SBFD symbols, or span both non-SBFD and SBFD symbols. For example, the SRS may span multiple time slots, residing on non-SBFD symbols in some time slots and on SBFD symbols in others. The terminal device determines independent power control parameters for SRS transmitted on non-SBFD symbols and on SBFD symbols, respectively. These power control parameters include the target received power and / or path loss compensation factor. The target received power is denoted as P. O_SRS,b,f,c (q s The road loss compensation factor is denoted as α. SRS,b,f,c (q s ).

[0171] For the above parameter P O_SRS,b,f,c (q s For example, for SRS transmitted on non-SBFD symbols, P O_SRS,b,f,c (q s Configured by p0, for SRS transmitted on SBFD symbols, P O_SRS,b,f,c (q s Configured by p0-SBFD.

[0172] For the above parameter α SRS,b,f,c (q s For example, for SRS transmitted on non-SBFD symbols, α SRS,b,f,c (q s ) is configured by alpha, for SRS transmitted on SBFD symbols, alpha SRS,b,f,c (q s Configured by alpha-SBFD.

[0173] In some possible implementations, for example, for SRS transmitted on non-SBFD symbols, P O_SRS,b,f,c (q s Configured by p0, α SRS,b,f,c (q s ) is configured by alpha; for SRS transmitted on SBFD symbols, P O_SRS,b,f,c (q s ) and α SRS,b,f,c (q sAt least one of the parameters in the SRS is configured differently from that of the SRS transmitted on non-SBFD symbols, while the rest are configured with the same parameters as the SRS transmitted on non-SBFD symbols. For example, for the SRS transmitted on SBFD symbols, P O_SRS,b,f,c (q s Configured by p0-SBFD, α SRS,b,f,c (q s Configured by alpha.

[0174] In some other possible implementations, for example, for SRS transmitted on non-SBFD symbols, P O_SRS,b,f,c (q s Configured by p0, α SRS,b,f,c (q s ) = 1; For SRS transmitted on SBFD symbols, P O_SRS,b,f,c (q s Configured by p0-SBFD, α SRS,b,f,c (q s ) = 1.

[0175] In some embodiments of this application, the seventeenth to twentieth parameters described above can be configured by RRC signaling.

[0176] For example, p0 is configured by RRC signaling; p0-SBFD is configured by RRC signaling, or p0-SBFD is the sum of p0 and offset6, where offset6 can be configured by RRC signaling. p0 and p0-SBFD can be associated with the same SRS resource set, or p0 and p0-SBFD can be associated with the first SRS resource set and the second SRS resource set, respectively.

[0177] For example, alpha is configured by RRC signaling; alpha-SBFD is configured by RRC signaling, or alpha-SBFD is the sum of alpha and offset7, where offset7 is configured by RRC signaling. alpha and alpha-SBFD can be associated with the same SRS resource set, or alpha and alpha-SBFD can be associated with the first SRS resource set and the second SRS resource set, respectively.

[0178] For the seventeenth and nineteenth parameters, in some possible implementations, p0 and p0-SBFD can be configured in the SRS-ResourceSet. The SRS-ResourceSet can be configured via dedicated RRC signaling, and can be configured per BWP.

[0179] Below is an example of an SRS-ResourceSet:

[0180] In some other possible implementations, p0 and offset6 can be configured in SRS-ResourceSet, where p0-SBFD is the sum of p0 and offset6.

[0181] For example, a terminal device is configured to use a first SRS-ResourceSet for transmitting SRS on non-SBFD symbols and a second SRS-ResourceSet for transmitting SRS on SBFD symbols. In each SRS-ResourceSet, a p0-s is configured, where p0 is ps in the first SRS-ResourceSet and p0-SBFD is p0-s in the second SRS-ResourceSet.

[0182] For the eighteenth and twentieth parameters, in some possible implementations, alpha and alpha-SBFD can be configured in the SRS-ResourceSet. The SRS-ResourceSet can be configured via dedicated RRC signaling and can be configured per BWP.

[0183] Below is an example of an SRS-ResourceSet:

[0184] In some other possible implementations, alpha and offset7 can be configured in SRS-ResourceSet, where alpha-SBFD is the sum of alpha and offset7.

[0185] For example, a terminal device is configured to use a first SRS-ResourceSet for transmitting SRS on non-SBFD symbols and a second SRS-ResourceSet for transmitting SRS on SBFD symbols. If an alpha-s is configured in each SRS-ResourceSet, then alpha is the alpha-s in the first SRS-ResourceSet and alpha-SBFD is the alpha-s in the second SRS-ResourceSet.

[0186] In some embodiments of this application, if p0-SBFD does not exist, the target receive power is determined based on the SRS transmitted on the SBFD symbol by p0; and / or, if alpha-SBFD does not exist, the target receive power is determined based on the SRS transmitted on the SBFD symbol by alpha.

[0187] For example, for an SRS transmitted on an SBFD symbol, if p0-SBFD exists, the terminal device uses p0-SBFD (e.g., to determine P) O_SRS,b,f,c (q s If p0-SBFD does not exist, for example, if p0-SBFD is not configured, or if offset6 is not configured, then P O_SRS,b,f,c (q s ) = 0, or the terminal device uses p0. For example, if the terminal device uses p0 for SRS transmitted on SBFD symbols, and p0 does not exist, then P O_SRS,b,f,c (q s ) = 0.

[0188] For example, for an SRS transmitted on an SBFD symbol, if alpha-SBFD exists, the terminal device uses alpha-SBFD (e.g., to determine α) SRS,b,f,c (q s If alpha-SBFD does not exist, for example, if alpha-SBFD is not configured, or if offset7 is not configured, then α SRS,b,f,c (q s α = 1, or the terminal device uses alpha. For example, if the terminal device uses alpha for SRS transmitted on SBFD symbols, then if alpha does not exist, then α SRS,b,f,c (q s ) = 1.

[0189] In some embodiments of this application, the terminal device determines the closed-loop power control state index for the SRS transmitted on non-SBFD symbols according to the twenty-first parameter l4, and determines the closed-loop power control state index for the SRS transmitted on SBFD symbols according to the twenty-second parameter l5.

[0190] For example, power control parameters also include a closed-loop power control state index l, with separate l used for SRS transmitted on non-SBFD symbols and on SBFD symbols. For h b,f,c The closed-loop power control state index l in (i,l) takes values ​​l4 and l5, which correspond to the SRS transmitted on non-SBFD symbols and SBFD symbols, respectively.

[0191] In the example above, l4 and l5 can be configured via RRC signaling, for example, configured as (l4=0, l5=1) or (l4=1, l5=0); or, l4 and l5 can be predefined, for example, predefined as (l4=0, l5=1) or (l4=1, l5=0).

[0192] 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 individually (the embodiments of FIG4, FIG6 and FIG7 are implemented individually), or one or more of the above embodiments can be combined (the embodiments of FIG4, FIG6 and FIG7 are implemented in combination or in any combination).

[0193] In the various embodiments described above, "before applying the TCI state" includes "after multiple TCI states are initially configured and before applying one of the TCI states," or "after multiple TCI states are configured in a reconfiguration with a synchronization process and before applying one of the TCI states." For example, "before applying the TCI state" can also be replaced with "after multiple TCI states are initially configured and before applying one of the TCI states," or "after multiple TCI states are configured in a reconfiguration with a synchronization process and before applying one of the TCI states," or others.

[0194] For example, a terminal device may initially be configured with multiple TCI states by higher-layer signaling, and these TCI states can be applied by the terminal device subsequently. The terminal device can still perform uplink transmissions before applying any of the TCI states. Embodiments of this application can determine power control parameters for uplink transmissions during this period.

[0195] For example, during cell handover reconfiguration (or reconfiguration with synchronization), the terminal device is configured with multiple TCI states by higher-layer signaling. These TCI states can be applied by the terminal device afterwards. Before the terminal device applies one of the TCI states, it can still perform uplink transmission. Embodiments of this application can determine power control parameters for uplink transmission during this period.

[0196] In the above embodiments, "before applying TCI state" can also be replaced with "before the first application of TCI state", which means before the terminal device applies TCI state for the first time in a new cell. The new cell can be a cell that the terminal device actively accesses, or it can be a cell that the terminal device is instructed to switch to during cell handover.

[0197] In the above embodiments, the terminal device can determine the first maximum transmit power P. CMAX To determine the transmit power for PUSCH, PUCCH, or SRS transmitted on non-SBFD symbols, the second maximum transmit power P is used.CMAX -SBFD determines the transmit power for PUSCH, PUCCH, or SRS transmitted on SBFD symbols.

[0198] For example, maximum transmit power P CMAX,f,c,1 (i)(P CMAX ) and P CMAX,f,c,2 (i)(P CMAX -SBFD) is used for PUSCH, PUCCH, or SRS transmitted on non-SBFD symbols and SBFD symbols, respectively. For example, the maximum transmit power P CMAX,f,c,PUSCH,1 (i) and P CMAX,f,c,PUSCH,2 (i) PUSCHs transmitted on non-SBFD symbols and SBFD symbols respectively; for example, maximum transmit power P CMAX,f,c,PUCCH,1 (i) and P CMAX,f,c,PUCCH,2 (i) PUCCHs transmitted on non-SBFD symbols and SBFD symbols respectively; for example, the maximum transmit power P CMAX,f,c,SRS,1 (i) and P CMAX,f,c,SRS,2 (i) SRS transmitted on non-SBFD symbols and SBFD symbols, respectively. For example, for P applied to non-SBFD symbols or SBFD symbols... CMAX,f,c (i) Different transmission opportunities i can use different (or independent) P CMAX,f,c (i).

[0199] 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.

[0200] Through the embodiments of this application, for both types of uplink transmissions on non-SBFD symbols and on SBFD symbols performed before the application of the TCI state, the terminal device does not use the two sets of power control parameters included in the TCI state, but instead uses two sets of power control parameters configured by the SIB message or RRC signaling. Therefore, even before applying the TCI state, the terminal device can use appropriate power control parameters for uplink transmissions in different interference environments for non-SBFD symbols and SBFD symbols, which helps ensure the reliability of uplink transmissions and avoids interference to other devices.
