Description

Method, device, terminal and readable storage medium for determining transmission power

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on November 24, 2023, with application number 202311583520.5 and application name “Method, device, terminal and readable storage medium for determining transmission power”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application belongs to the field of communication technology, and specifically relates to a method, device, terminal and readable storage medium for determining transmission power. Background Art

[0003] Currently, in the New Radio (NR) system, when a terminal performs full-duplex transmission and is in a connected state, the network-side device can send a Transmit Power Control (TPC) command to the terminal, so that the terminal can determine the transmit power of the Sounding Reference Signal (SRS) according to the TPC command to ensure the coverage of the SRS without affecting other downlink transmissions of the terminal.

[0004] However, since the terminal may be in a non-connected state (i.e., idle or inactive), the network-side device may not be able to send a TPC command to the terminal. This may cause the terminal to transmit SRS with inaccurate transmission power. Therefore, it may affect the terminal's other downlink transmissions, or cause the SRS coverage range to be smaller, thereby reducing the reliability of the terminal's other downlink transmissions, or causing the network-side device to be unable to receive the SRS, thus resulting in poor communication performance of the terminal. Summary of the Invention

[0005] The embodiments of the present application provide a method, apparatus, terminal, and readable storage medium for determining transmission power, which can solve the problem of reducing the interference to other downlink transmissions caused by transmitting SRS when the terminal is performing full-duplex transmission, while reducing the probability that the network-side device cannot receive SRS.

[0006] In a first aspect, a method for determining transmission power is provided, which is executed by a terminal. The method includes: when the terminal performs full-duplex transmission, determining the transmission power of transmitting a first SRS when the terminal is in a non-connected state based on a first object, the first object including at least one of the following: a resource type corresponding to the first reference signal; a reference signal set corresponding to the first reference signal; and a resource type corresponding to the first SRS.

[0007] According to a second aspect, a transmission power determination device is provided, which includes: a determination module for determining, in the case of full-duplex transmission, the transmission power of transmitting a first SRS when the transmission power determination device is in a non-connected state according to a first object, wherein the first object includes at least one of the following: a resource type corresponding to the first reference signal; a reference signal set corresponding to the first reference signal; and a resource type corresponding to the first SRS.

[0008] In a third aspect, a terminal is provided, comprising a processor and a memory, wherein the memory stores a program or instruction that can be run on the processor, and when the program or instruction is executed by the processor, the steps of the method described in the first aspect are implemented.

[0009] In a fourth aspect, a terminal is provided, comprising a processor and a communication interface, wherein the processor is used to determine, in the case of full-duplex transmission, the transmission power of a first SRS transmitted when the terminal is in a non-connected state according to a first object, and the first object includes at least one of the following: a resource type corresponding to the first reference signal; a reference signal set corresponding to the first reference signal; and a resource type corresponding to the first SRS.

[0010] In a fifth aspect, a readable storage medium is provided, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the method described in the first aspect are implemented.

[0011] In a sixth aspect, a chip is provided, comprising a processor and a communication interface, wherein the communication interface is coupled to the processor, and the processor is configured to run a program or instruction to implement the steps of the method described in the first aspect.

[0012] In a seventh aspect, a computer program / program product is provided, wherein the computer program / program product is stored in a storage medium, and the program / program product is executed by at least one processor to implement the steps of the method described in the first aspect.

[0013] In an embodiment of the present application, when the terminal performs full-duplex transmission, the transmit power of the first SRS transmitted when the terminal is in a non-connected state can be determined based on the first object, wherein the first object includes at least one of the resource type corresponding to the first reference signal, the reference signal set corresponding to the first reference signal, and the resource type corresponding to the first SRS. Since, when the terminal performs full-duplex transmission, the terminal can accurately determine the transmit power of the first SRS transmitted when the terminal is in a non-connected state based on the resource type corresponding to the first reference signal, the reference signal set corresponding to the first reference signal, and the resource type corresponding to the first SRS, without having to determine it based on the TPC command sent by the network device, it can avoid the situation where the terminal is affected in performing other downlink transmissions, or can avoid the coverage range of the SRS being small, thereby improving the reliability of the terminal in performing other downlink transmissions, or enabling the network-side device to receive the SRS, thereby improving the communication performance of the terminal.

[0023] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0024] The following describes the terms involved in the embodiments of the present application.

[0025] 1. TPC Command

[0026] TPC commands can be used to compensate for channel variations caused by fast fading. With respect to current Long Term Evolution (LTE) systems, the Physical Uplink Control Channel (PUCCH) power can be adjusted by TPC commands signaled in the downlink control information (DCI), while the Physical Uplink Shared Channel (PUSCH) or SRS power can be adjusted by TPC commands signaled in the uplink grant DCI. In addition, for uplink transmissions without associated DCI, such as Semi-Persistent Scheduling (SPS), periodic channel state information (CSI) or SRS, TPC commands can be signaled to a specific terminal group (UE group) by using DCI format 3 / 3A. There are two types of TPC commands used to update the uplink transmit power; one is a cumulative TPC command and the other is an absolute TPC command. Cumulative TPC commands are well-suited for fine-tuning a terminal's transmit power using relatively small steps of TPC values. Absolute TPC commands, on the other hand, can be used to instantly increase a terminal's transmit power using relatively large steps of TPC values.

[0027] 2. Uplink SRS resources

[0028] Currently, NR supports uplink beam training through SRS. However, in the initial access phase, there is no uplink beam management because the terminal does not send SRS. The uplink beam used by the terminal when sending the preamble and message 3 (Msg3), or message A (MsgA) depends on the implementation method of the terminal. However, in NR's four-step random access (4-step RACH), there is a requirement for the consistency of the uplink beam used to send Msg3 and the uplink beam of the PUCCH carrying the Hybrid Automatic Repeat request-Acknowledgement (HARQ-ACK) of message 4 (Msg4). That is, the terminal needs to ensure that the uplink beam used when sending Msg3 is the same as the uplink beam used to send the PUCCH carrying the HARQ-ACK of Msg4. Similarly, for two-step random access (2-step RACH), the terminal must ensure that the uplink beam used to send Msg A is the same as the uplink beam used to send the PUCCH carrying the HARQ-ACK for Msg B. In the Radio Resource Control (RRC) connected state, the SRS-based uplink beam training results can be used for subsequent uplink transmissions.

[0029] Subsequent communication systems may introduce SRS signals for uplink beam management or uplink capacity enhancement when the terminal is in idle / inactive state. For example, the association of synchronization signal / physical broadcast channel block (SS) / (PBCH) block (SSB) / channel state information reference signal (CSI-RS) with SRS can be introduced to enable the terminal to perform uplink beam training before cell access, such as determining a more appropriate physical random access channel (PRACH) transmission beam, thereby improving PRACH reception reliability. On the other hand, for example, the association of PRACH resources / MsgA resources / MsgA PUSCH resources with multiple SRS resources can be introduced to enable different terminals to use different associated SRS beams to send the same PRACH preamble, thereby improving PRACH capacity. Alternatively, for example, multiple PRACH / MsgA resources / MsgA PUSCH resources may be associated with the SRS, thereby supporting multiple repetitions of PRACH / MsgA resources / MsgA PUSCH resources using the same SRS resource, thereby improving the reliability of PRACH / MsgA resources / MsgA PUSCH resource transmission.

[0030] In addition, in the current NR system, when the UE is in an inactive state, SRS resources can be configured to send SRS signals for terminal positioning in the inactive state.

[0035] The following, in conjunction with the accompanying drawings, describes in detail the transmit power determination method, device, terminal, and readable storage medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0036] FIG2 is a flow chart showing a method for determining transmit power according to an embodiment of the present application. As shown in FIG2 , a method for determining transmit power according to an embodiment of the present application may include the following step 101 .

[0037] Step 101: When a terminal performs full-duplex transmission, the terminal determines, according to a first object, a transmit power for transmitting a first SRS when the terminal is in a non-connected state.

[0038] In some embodiments of the present application, the terminal can receive configuration information from a network side device, where the configuration information is used to configure the terminal to send a first SRS, and determine the first SRS based on the configuration information, so that the terminal can determine the transmission power of the first SRS when the terminal is in a non-connected state based on the first object when performing full-duplex transmission.

[0039] In the embodiment of the present application, the first object includes at least one of the following:

[0040] The resource type corresponding to the first reference signal;

[0041] a reference signal set corresponding to the first reference signal;

[0042] The resource type corresponding to the first SRS.

[0043] In some embodiments of the present application, the first reference signal is a reference signal associated with the first SRS.

[0044] It should be noted that the above-mentioned “reference signal associated with the first SRS” can be understood as: a reference signal that matches the spatial attribute information of the first SRS.

[0045] In some embodiments of the present application, the above configuration information also includes spatial attribute information of the first SRS, so that the terminal can determine the first reference signal according to the spatial attribute information of the first SRS.

[0046] In some embodiments of the present application, the first reference signal may be a downlink reference signal, which may include at least one of the following: a synchronization signal / physical broadcast channel block (Synchronization Signal and PBCH block, SSB), a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), and a phase tracking reference signal (PTRS). Of course, the first reference signal may also include other reference signals, which are not limited in the embodiments of the present application.

[0047] In some embodiments of the present application, the resource type corresponding to the first reference signal may be understood as: the resource type of the time domain resources and / or frequency domain resources occupied by the first reference signal.

[0048] In some embodiments of the present application, the first object includes a resource type corresponding to the first reference signal, and the resource type corresponding to the first reference signal includes at least one of the following:

[0049] A first resource type, where the first resource type is used to represent a type of time domain resource whose time domain format is downlink;

[0050] The second resource type is used to represent a type of time domain resources whose time domain format is the first format.

[0051] In some embodiments of the present application, the above-mentioned time domain format may also be a time domain type. The time domain format (time domain type) corresponding to the first reference signal may be indicated by a full-duplex subband configuration or a full-duplex subband. For example, the time domain format indicated by TDD-UL-DL-Configuration may be, for example, downlink (DL), uplink (UL), and flexible; or, the time domain type indicated by xdd-UL-DL-Configuration may be, for example, full downlink (Full DL), full uplink (Full UL), and full-duplex subband (Sub-Band Full Duplex, SBFD) x; or, the frequency domain format (Frequency Format) indicated by the full-duplex subband configuration may be, for example, downlink subband (DL Subband), uplink subband (UL Subband), guard subband (Guard Band), downlink bandwidth part (DL Band Width Part, DL BWP), and uplink bandwidth part (UL BWP).

[0052] In the embodiment of the present application, the first format is a time domain format for full-duplex transmission, and the frequency domain resources corresponding to the time domain resources of the first format include an uplink sub-band and a downlink sub-band.

[0053] In some embodiments of the present application, the entire bandwidth corresponding to the time domain resources in the first format includes both uplink sub-bands and downlink sub-bands.

[0054] In this way, it can be seen that the terminal can determine the transmission power of the first SRS from different transmission powers when the resource type corresponding to the first reference signal includes different resource types, that is, when the resource types of the time-frequency domain resources occupied by the first reference signal are different. Therefore, the accuracy of the determined transmission power of the first SRS can be improved, so that when full-duplex transmission is performed, that is, when receiving downlink transmission (for example, downlink transmission received by the terminal from the network side device, or downlink transmission received by the terminal from other devices) and sending the first SRS according to the determined transmission power of the first SRS, the interference to the downlink transmission caused by sending the first SRS can be reduced, thereby improving the performance of the downlink transmission, and the coverage range of the first SRS can be guaranteed; and, when the subsequent terminal performs half-duplex transmission, that is, when the first SRS is sent only according to the determined transmission power of the first SRS, the coverage range of the first SRS can be guaranteed.

[0055] In some embodiments of the present application, the second resource type includes at least one of the following:

[0056] A third resource type, where the third resource type is used to represent a type of time domain resource whose time domain format is the first format and whose interval between the corresponding uplink subband and the corresponding downlink subband is greater than or equal to a first preset value;

[0057] The fourth resource type is used to represent a type of time domain resource whose time domain format is the first format and whose interval between the corresponding uplink subband and the corresponding downlink subband is less than or equal to the second preset value.

[0058] It can be understood that the above-mentioned third resource type is used to characterize a type of time domain resource in which the frequency domain resource corresponding to the time domain resource includes an uplink subband and a downlink subband, and the interval between the corresponding uplink subband and the corresponding downlink subband is greater than or equal to a first preset value; the above-mentioned fourth resource type is used to characterize a type of time domain resource in which the frequency domain resource corresponding to the time domain resource includes an uplink subband and a downlink subband, and the interval between the corresponding uplink subband and the corresponding downlink subband is less than or equal to a second preset value.

[0059] In some embodiments of the present application, the first preset value and the second preset value may be the same or different.

[0060] It can be seen that since the second resource type can also be divided into a third resource type and a fourth resource type, when the resource types of the time-frequency domain resources occupied by the first reference signal are different, the terminal can determine the transmission power of the first SRS from more different transmission powers, thereby further improving the accuracy of the determined transmission power of the first SRS.

[0061] In some embodiments of the present application, the reference signal set corresponding to the first reference signal may be understood as: the reference signal set to which the first reference signal belongs.

[0062] In some embodiments of the present application, the first object includes a reference signal set corresponding to the first reference signal, and the reference signal set corresponding to the first reference signal includes at least one of the following:

[0063] A first reference signal set, where the first reference signal set includes a reference signal whose time domain format is downlink of a corresponding time domain resource;

[0064] a second reference signal set, the second reference signal set including reference signals whose time domain format of corresponding time domain resources is a first format;

[0065] a third reference signal set, the third reference signal set including reference signals whose time domain format of corresponding time domain resources is the first format and whose interval between the corresponding uplink subband and the corresponding downlink subband is greater than or equal to a third preset value;

[0066] A fourth reference signal set includes reference signals whose time domain format of corresponding time domain resources is the first format and whose interval between the corresponding uplink subband and the corresponding downlink subband is less than or equal to a fourth preset value.

[0067] In the embodiment of the present application, the first format is a time domain format for full-duplex transmission, and the frequency domain resources corresponding to the time domain resources of the first format include an uplink sub-band and a downlink sub-band.

[0068] In some embodiments of the present application, the third preset value and the fourth preset value may be the same or different, and the third preset value and the first preset value may be the same or different.

[0069] In some embodiments of the present application, the resource type corresponding to the reference signals included in the first reference signal set is the above-mentioned first resource type, the resource type corresponding to the reference signals included in the second reference signal set is the above-mentioned second resource type, the resource type corresponding to the reference signals included in the third reference signal set is the above-mentioned third resource type, and the resource type corresponding to the reference signals included in the fourth reference signal set is the above-mentioned fourth resource type.

[0070] In this way, it can be seen that the terminal can determine the transmission power of the first SRS from different transmission powers when the reference signal set corresponding to the first reference signal includes different reference signal sets, that is, when the resource types of the time-frequency domain resources occupied by the first reference signal are different. Therefore, the accuracy of the determined transmission power of the first SRS can be improved, so that when full-duplex transmission is performed, that is, when receiving downlink transmission and sending the first SRS according to the determined transmission power of the first SRS, the interference to the downlink transmission caused by sending the first SRS can be reduced, thereby improving the performance of the downlink transmission, and the coverage range of the first SRS can be guaranteed; and, when the subsequent terminal performs half-duplex transmission, that is, when the first SRS is sent only according to the determined transmission power of the first SRS, the coverage range of the first SRS can be guaranteed.

[0071] In some embodiments of the present application, the first object includes a resource type corresponding to a first SRS, and the resource type corresponding to the first SRS includes at least one of the following:

[0072] A fifth resource type, where the fifth resource type is used to represent a type of time domain resource whose time domain format is downlink;

[0073] a sixth resource type, where the sixth resource type is used to represent a type of time domain resource whose time domain format is the first format and whose corresponding reference signal does not include the second reference signal;

[0074] a seventh resource type, where the seventh resource type is used to represent a type of time domain resource whose time domain format is the first format and whose corresponding reference signal includes the second reference signal;

[0075] An eighth resource type is used to represent a type of time domain resources whose time domain format is the first format and whose interval between time domain resources corresponding to the first reference signal is greater than or equal to a fifth preset value.

[0076] In the embodiment of the present application, the first format is a time domain format for full-duplex transmission, and the frequency domain resources corresponding to the time domain resources of the first format include an uplink sub-band and a downlink sub-band.

[0077] In some embodiments of the present application, the second reference signal may include at least one of the following: a common signal and a broadcast signal. The broadcast signal may include at least one of the following: an SSB, a system information block (SIB), a master information block (MIB), a paging signal, etc.

[0078] In this way, it can be seen that the terminal can determine the transmission power of the first SRS from different transmission powers when the resource type corresponding to the first SRS includes different resource types, that is, when the resource types of the time-frequency domain resources occupied by the first SRS are different. Therefore, the accuracy of the determined transmission power of the first SRS can be improved, so that when full-duplex transmission is performed, that is, when receiving downlink transmission and sending the first SRS according to the determined transmission power of the first SRS, the interference to the downlink transmission caused by sending the first SRS can be reduced, thereby improving the performance of the downlink transmission, and the coverage range of the first SRS can be guaranteed; and, when the subsequent terminal performs half-duplex transmission, that is, when the first SRS is sent only according to the determined transmission power of the first SRS, the coverage range of the first SRS can be guaranteed.

[0079] An embodiment of the present application provides a method for determining transmit power. When a terminal performs full-duplex transmission, the transmit power of a first SRS transmitted when the terminal is in a non-connected state can be determined based on a first object, wherein the first object includes at least one of a resource type corresponding to a first reference signal, a reference signal set corresponding to the first reference signal, and a resource type corresponding to the first SRS. Since, when the terminal performs full-duplex transmission, the terminal can accurately determine the transmit power of the first SRS transmitted when the terminal is in a non-connected state based on at least one of the resource type corresponding to the first reference signal, the reference signal set corresponding to the first reference signal, and the resource type corresponding to the first SRS, without having to determine the transmit power based on a TPC command sent by a network device, it is possible to avoid situations that affect the terminal's downlink transmission, or to avoid a small coverage range of the SRS, thereby improving the reliability of the terminal's downlink transmission, or enabling the network-side device to receive the SRS, thereby improving the communication performance of the terminal.

[0080] The following is an example to illustrate a specific solution in which the terminal determines the transmit power for transmitting the first SRS.

[0081] Example 1:

[0082] In some embodiments of the present application, the first object includes at least one of the following: a resource type corresponding to the first reference signal, and a reference signal set corresponding to the first reference signal. Optionally, in conjunction with FIG2 , as shown in FIG3 , step 101 can be specifically implemented by the following steps 101a and 101b.

[0083] Step 101a: When performing full-duplex transmission, the terminal obtains a target power parameter according to at least one of a resource type corresponding to the first reference signal and a reference signal set corresponding to the first reference signal.

[0084] In some embodiments of the present application, the target power parameter includes at least one of the following:

[0085] Target received power;

[0086] Power offset value;

[0087] Path loss compensation factor;

[0088] TPC command;

[0089] Power compensation factor;

[0090] Maximum transmit power;

[0091] Path loss parameter.

[0092] In some embodiments of the present application, the power offset value may be a positive number, a negative number, or 0.

[0093] In some embodiments of the present application, the above-mentioned path loss parameters may include a path loss estimation value, a reference signal corresponding to the path loss estimation, etc.

[0094] In some embodiments of the present application, the network side device may pre-configure corresponding power parameters for the resource type corresponding to the first reference signal and / or the reference signal set corresponding to the first reference signal, so that the terminal can directly determine the power parameter corresponding to the resource type corresponding to the first reference signal as at least part of the power parameter of the target power parameter, and / or can directly determine the power parameter corresponding to the reference signal set corresponding to the first reference signal as at least part of the power parameter of the target power parameter.

[0095] In some embodiments of the present application, in combination with Figure 3, as shown in Figure 4, before the above step 101a, the transmission power determination method provided in the embodiment of the present application may further include the following step 201, and the above step 101a can be specifically implemented through the following step 101a1.

[0096] Step 201: A terminal receives first power configuration information related to a first reference signal.

[0097] In an embodiment of the present application, the first power configuration information includes at least one of the following: at least one power parameter corresponding to at least one reference signal set, and at least one power parameter corresponding to at least one resource type.

[0098] In some embodiments of the present application, when the first power configuration information includes at least one power parameter corresponding to at least one reference signal set, the above-mentioned first object includes the reference signal set corresponding to the first reference signal; and / or, when the first power configuration information includes at least one power parameter corresponding to at least one resource type, the above-mentioned first object includes the resource type corresponding to the first reference signal.

[0099] In some embodiments of the present application, each of the at least one power parameter includes at least one of the following:

[0100] Target received power;

[0101] Power offset value;

[0102] Path loss compensation factor;

[0103] TPC command;

[0104] Power compensation factor;

[0105] Maximum transmit power;

[0106] Path loss parameter.

[0107] It can be understood that since the target power parameter is one of at least one power parameter, the target power parameter also includes at least one of the target receiving power, power offset value, path loss compensation factor, TPC command, power compensation factor, maximum transmit power, and path loss parameter.

[0108] In some embodiments of the present application, the power offset value may be a positive number, a negative number, or 0.

[0109] In some embodiments of the present application, the above-mentioned path loss parameters may include a path loss estimation value, a reference signal corresponding to the path loss estimation, etc.

[0110] In some embodiments of the present application, the terminal may receive first power configuration information from a network-side device.

[0111] Step 101a1: The terminal determines, from at least one power parameter, a target power parameter corresponding to at least one of a resource type corresponding to a first reference signal and a reference signal set corresponding to the first reference signal.

[0112] In some embodiments of the present application, the terminal may first determine, from at least one reference signal set, a reference signal set that is identical to the reference signal set corresponding to the first reference signal, and then determine the power parameter corresponding to the reference signal set as at least part of the power parameter of the target power parameter; and / or, the terminal may first determine, from at least one resource type, a resource type that is identical to the resource type corresponding to the first reference signal, and then determine the power parameter corresponding to the resource type as at least part of the power parameter of the target power parameter.

[0113] It can be seen that the terminal can receive first power configuration information including at least one power parameter corresponding to at least one reference signal set and / or at least one power parameter corresponding to at least one resource type, so that the terminal can directly determine the target power parameter based on at least one of the resource type corresponding to the first reference signal and the reference signal set corresponding to the first reference signal.

[0114] Step 101b: The terminal determines, according to the target power parameter, the transmit power for transmitting the first SRS when the terminal is in the unconnected state.

[0115] In some embodiments of the present application, when the target power parameters include at least one of the target receiving power, the path loss compensation factor, the power compensation factor, the maximum transmitting power and the path loss parameter, the terminal can determine the transmitting power corresponding to the target receiving power as the transmitting power for transmitting the first SRS.

[0116] In some embodiments of the present application, when the target power parameter includes a power offset value, the terminal may use a first algorithm to calculate the transmit power for transmitting the first SRS based on the power offset value. Optionally, the target power parameter includes the first power offset value. Step 101b may be implemented through steps 101b1 and 101b2 described below.

[0117] Step 101b1: The terminal determines a first transmit power based on a first power offset value.

[0118] In some embodiments of the present application, the terminal may first use the third transmit power obtained by uplink power control calculation, and then determine the first transmit power according to the third transmit power and the first power offset value.

[0119] Step 101b2: The terminal determines, based on the first transmit power and the second transmit power, the transmit power for transmitting the first SRS when the terminal is in the unconnected state.

[0120] In this embodiment of the present application, the second transmission power is the maximum transmission power of the terminal.

[0121] In some embodiments of the present application, the above-mentioned maximum transmit power may be understood as: the maximum transmit power allowed by the cell where the terminal resides.

[0122] In some embodiments of the present application, the terminal may determine the minimum transmit power between the first transmit power and the second transmit power as the transmit power for transmitting the first SRS when the terminal is in a non-connected state.

[0123] It can be understood that the terminal can adopt the first algorithm to calculate according to the first power offset value to obtain the transmit power for transmitting the first SRS when the terminal is in the unconnected state.

[0124] The first algorithm may specifically be: SRS =min{P CMAX , P UL PC,SRS +offset};

[0125] Among them, the P SRS is the transmission power of the first SRS, the P CMAX is the maximum transmit power of the terminal (i.e., the second transmit power), P UL_PC,SRS The third transmit power is obtained by the terminal through uplink power control calculation, and offset is the first power offset value.

[0126] It should be noted that, for the description of how the terminal determines the maximum transmit power of the terminal, reference may be made to the specific description in the relevant technology, and the embodiments of the present application will not be elaborated here.

[0127] In some examples, the terminal may use the second algorithm to calculate the third transmit power P UL_PC,SRS .

[0128] The second algorithm may specifically be: P = min{P CMAX ,[p0(j)+α(k)*PL(q)±f(l)+[10lgM+Δ]};

[0129] Among them, P CMAX is the configured transmit power of the terminal on the uplink carrier (the maximum transmit power allowed for the uplink carrier), and p0(j) is the open-loop receiver power target value, which is related to the target signal-to-noise interference ratio (SINR) and interference strength expected by the network-side device. The larger the target SINR value, the higher the uplink transmit power and the higher the SINR at the receiver. PL(q) is the path loss estimate, where q is the index, and one path loss estimate is selected from a set of path loss estimates maintained by the terminal. For the same terminal, different reference signals in the same serving cell may also experience different path losses. For example, a wider SSB beamwidth results in lower beamforming gain, resulting in a larger path loss estimate; while a narrower CSI-RS beam results in higher beamforming gain, resulting in a smaller path loss estimate. Therefore, the same terminal needs to maintain multiple path loss estimates and retrieve a path loss estimate based on the index configured or indicated by the network to calculate the transmit power. The closed-loop portion, f(l), is the lth power control offset (adjustment) state value, which can quickly adjust the transmission power of a terminal for a specific transmission. The adjustment is based on the performance of the previous transmission, and the adjustment information is quickly adjusted through physical layer signaling (such as DCI) (the relevant parameters are still quasi-statically configured by RRC high-level signaling). This type of adjustment is called closed-loop adjustment. For example, if the network side equipment finds that the terminal's transmission power is too high, the network side equipment can use DCI to notify the terminal to reduce the transmission power by 1 decibel (dB) when scheduling the next uplink transmission of the same type. The closed-loop power control information carried in the DCI is called TPC and is expressed as δ(l).

[0130] In this way, it can be seen that since the terminal can first determine the first transmission power based on the first power offset value, and then determine the transmission power of transmitting the first SRS when the terminal is in a non-connected state based on the maximum transmission power of the terminal and the first transmission power, that is, the determined transmission power for transmitting the first SRS takes into account the maximum transmission power of the terminal. Therefore, it can avoid the situation where the determined transmission power for transmitting the first SRS is greater than the maximum transmission power of the terminal.

[0131] In some embodiments of the present application, when the target power parameter includes a TPC command, the terminal may determine the transmit power indicated by the TPC command as the transmit power for transmitting the first SRS.

[0132] It can be seen that since the terminal can directly obtain the corresponding target power parameter based on the resource type corresponding to the first reference signal and at least one of the reference signal sets corresponding to the first reference signal, the terminal can accurately determine the transmission power of the first SRS based on the target power parameter.

[0133] For example, assuming that the target power parameter includes a first power offset value and the first reference signal is SSB, the terminal can first receive first power configuration information related to SSB, where the first power configuration information includes a power offset value (power offset) corresponding to SSB set 1 (for example, the first reference signal set in the above embodiment), for example, power offset 1 = X, and a power offset value (power offset) corresponding to SSB set 2 (for example, the second reference signal set in the above embodiment), for example, power offset 2 = Y.

[0134] Thus, when the terminal operates in full-duplex transmission mode, in the idle / inactive state, the terminal initiates the transmission of the first SRS, and can obtain the first power offset value power offset 1 (i.e., X) according to the SSB set (e.g., SSB set 1) corresponding to the first SSB associated with the first SRS, and adopt the first algorithm to calculate the transmit power of the first SRS according to power offset 1; wherein the first algorithm is: P SRS =min{P CMAX , P UL PC,SRS +offset 1}, the P SRS is the transmission power of the first SRS, the P CMAX is the maximum transmit power of the terminal (i.e., the second transmit power), P UL_PC,SRS is the third transmit power calculated by the terminal using uplink power control, and offset 1 is the above power offset 1 (ie, X). Or,

[0135] When the terminal operates in full-duplex transmission mode, in the idle / inactive state, the terminal initiates transmission of a first SRS, and can obtain a first power offset value power offset 2 (i.e., Y) according to an SSB set (e.g., SSB set 2) corresponding to a first SSB associated with the first SRS, and adopt a first algorithm to calculate the transmit power of the first SRS according to power offset 2; wherein the first algorithm is: P SRS =min{P CMAX , P UL PC,SRS +offset 2}, the P SRSis the transmission power of the first SRS, the P CMAX is the maximum transmit power of the terminal (i.e., the second transmit power), P UL_PC,SRS is the third transmit power calculated by the terminal using uplink power control, and offset 2 is the above power offset 2 (ie, Y).

[0136] Example 2:

[0137] In some embodiments of the present application, the first object includes a resource type corresponding to the first SRS. Optionally, in combination with Figure 2 , as shown in Figure 5 , the step 101 can be specifically implemented through the following steps 101c and 101d.

[0138] Step 101c: When performing full-duplex transmission, the terminal obtains a target power parameter according to the resource type corresponding to the first SRS.

[0139] In some embodiments of the present application, the target power parameter includes at least one of the following:

[0140] Target received power;

[0141] Power offset value;

[0142] Path loss compensation factor;

[0143] Transmit power control TPC command;

[0144] Power compensation factor;

[0145] Maximum transmit power;

[0146] Path loss parameter.

[0147] In some embodiments of the present application, the network side device may pre-configure the corresponding power parameter for the resource type corresponding to the first SRS, so that the terminal may directly determine the power parameter corresponding to the resource type corresponding to the first SRS as the target power parameter.

[0148] In some embodiments of the present application, in combination with Figure 5, as shown in Figure 6, before the above-mentioned step 101c, the transmission power determination method provided in the embodiment of the present application may further include the following step 301, and the above-mentioned step 101c can be specifically implemented through the following step 101c1.

[0149] Step 301: A terminal receives second power configuration information related to a first SRS.

[0150] In an embodiment of the present application, the second power configuration information includes at least one power parameter corresponding to at least one resource type.

[0151] In some embodiments of the present application, each of the at least one power parameter includes at least one of the following:

[0152] Target received power;

[0153] Power offset value;

[0154] Path loss compensation factor;

[0155] TPC command;

[0156] Power compensation factor;

[0157] Maximum transmit power;

[0158] Path loss parameter.

[0159] In some embodiments of the present application, the terminal may receive the second power configuration information from the network side device.

[0160] Step 101c1: The terminal determines a target power parameter corresponding to the resource type corresponding to the first SRS from at least one power parameter.

[0161] In some embodiments of the present application, the terminal may first determine a resource type that is the same as the resource type corresponding to the first SRS from at least one resource type, and then determine the power parameter corresponding to the resource type as the target power parameter.

[0162] As can be seen, the terminal can receive the second power configuration information including at least one power parameter corresponding to at least one resource type, so that the terminal can directly determine the target power parameter accurately according to the resource type corresponding to the first SRS.

[0163] Step 101d: The terminal determines, according to the target power parameter, the transmit power for transmitting the first SRS when the terminal is in the unconnected state.

[0164] It should be noted that, for the description of the terminal determining the transmit power of the first SRS when the terminal is in a non-connected state according to the target power parameter, reference may be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0165] As can be seen, since the terminal can directly obtain the corresponding target power parameter according to the resource type corresponding to the first SRS, the terminal can accurately determine the transmit power for transmitting the first SRS according to the target power parameter.

[0166] In some embodiments of the present application, the target power parameter includes a first power offset value. The step 101d can be implemented by the following steps 101d1 and 101d2.

[0167] Step 101d1: The terminal determines a first transmit power based on a first power offset value.

[0168] Step 101d2: The terminal determines, based on the first transmit power and the second transmit power, the transmit power for transmitting the first SRS when the terminal is in the unconnected state.

[0169] In this embodiment of the present application, the second transmission power is the maximum transmission power of the terminal.

[0170] In this way, it can be seen that since the terminal can first determine the first transmission power based on the first power offset value, and then determine the transmission power of transmitting the first SRS when the terminal is in a non-connected state based on the maximum transmission power of the terminal and the first transmission power, that is, the determined transmission power for transmitting the first SRS takes into account the maximum transmission power of the terminal. Therefore, it can avoid the situation where the determined transmission power for transmitting the first SRS is greater than the maximum transmission power of the terminal.

[0171] For example, assuming that the target power parameter includes a power offset value and the first reference signal is SSB, the terminal can first receive second power configuration information related to the first SRS, where the second power configuration information includes a power offset value (power offset) corresponding to type 1 (for example, the fifth resource type in the above embodiment), for example, power offset 1 = 0, a power offset value (power offset) corresponding to type 2 (for example, the sixth resource type in the above embodiment), for example, power offset 2 = X, a power offset value (power offset) corresponding to type 3 (for example, the seventh resource type in the above embodiment), for example, power offset 3 = Y, and a power offset value (power offset) corresponding to type 4 (for example, the eighth resource type in the above embodiment), for example, power offset 4 = Z.

[0172] Thus, when the terminal operates in full-duplex transmission mode, in the idle / inactive state, the terminal initiates the transmission of the first SRS, and can obtain the first power offset value power offset 1 (i.e., 0) according to the resource type (e.g., type 1) corresponding to the first SRS, and adopt the first algorithm to calculate the transmit power of the first SRS according to power offset 1; wherein, the first algorithm is: P SRS =min{P CMAX , P UL PC,SRS}, the P SRS is the transmission power of the first SRS, the P CMAX is the maximum transmit power of the terminal (i.e., the second transmit power), P UL_PC,SRSis the third transmit power calculated by the terminal using uplink power control. Since power offset 1 is 0, power offset 1 is not reflected in the first algorithm. Alternatively, when the terminal operates in full-duplex transmission mode, in the idle / inactive state, the terminal initiates transmission of the first SRS. The first power offset value power offset 2 (i.e., X) can be obtained according to the resource type corresponding to the first SRS (e.g., type 2), and the first algorithm is used to calculate the transmit power of the first SRS according to power offset 2; wherein the first algorithm is: P SRS =min{P CMAX , P UL PC,SRS +offset2}, the P SRS is the transmission power of the first SRS, the P CMAX is the maximum transmit power of the terminal (i.e., the second transmit power), P UL_PC,SRS is the third transmit power calculated by the terminal using uplink power control, and the offset2 is the above-mentioned power offset 2 (i.e., X). Alternatively, when the terminal operates in full-duplex transmission mode, in the idle / inactive state, the terminal initiates transmission of the first SRS, and can obtain power offset 3 (i.e., Y) according to the resource type corresponding to the first SRS (e.g., type 3), and adopt a first algorithm to calculate the transmit power of the first SRS according to power offset 3; wherein the first algorithm is: P SRS =min{P CMAX , P UL PC,SRS +offset3}, the P SRS is the transmission power of the first SRS, the P CMAX is the maximum transmit power of the terminal (i.e., the second transmit power), P UL_PC,SRS is the third transmit power calculated by the terminal using uplink power control, and the offset3 is the above-mentioned power offset 3 (i.e., Y). Alternatively, when the terminal operates in full-duplex transmission mode, in the idle / inactive state, the terminal initiates the transmission of the first SRS, and can obtain power offset 4 (i.e., Z) according to the resource type corresponding to the first SRS (e.g., type 4), and adopt a first algorithm to calculate the transmit power of the first SRS according to power offset 4; wherein the first algorithm is: P SRS =min{P CMAX , P UL PC,SRS +offset4}, the P SRS is the transmission power of the first SRS, the P CMAXis the maximum transmit power of the terminal (i.e., the second transmit power), P UL_PC,SRS It is the third transmit power calculated by the terminal using uplink power control, and the offset4 is the power offset 4 (ie, Z).

[0173] Example 3:

[0174] Assuming that the target power parameter includes a first power offset value and the first reference signal resource is an SSB, the terminal can first receive first power configuration information and second power configuration information related to the SSB, where the first power configuration includes a power offset value (power offset) corresponding to SSB set 1 (for example, the first reference signal set in the above embodiment), for example, power offset 1, and a power offset value (power offset) corresponding to SSB set 2 (for example, the second reference signal set in the above embodiment), for example, power offset 2. The second power configuration information includes a power offset value (power offset) corresponding to type 1 (for example, the fifth resource type in the above embodiment), for example, power offset 1, a power offset value (power offset) corresponding to type 2 (for example, the sixth resource type in the above embodiment), for example, power offset 2, a power offset value (power offset) corresponding to type 3 (for example, the seventh resource type in the above embodiment), for example, power offset 3, and a power offset value (power offset) corresponding to type 4 (for example, the eighth resource type in the above embodiment), for example, power offset 4.

[0175] When the terminal selects an SRS transmission opportunity (the seventh resource type) on a time domain resource with a time domain format of UL to initiate transmission of the first SRS, the first SSB associated with the first SRS is included in SSB set 1, and the transmission power of the first SRS is determined according to the following formula: SRS =min{P CMAX , P UL PC,SRS +offset1}, where P UL_PC,SRS The third transmit power determined by uplink power control, P CMAX represents the maximum transmit power of the terminal (ie, the second transmit power), and offset1 is the first power offset value power offset 3. Or,

[0176] When the terminal selects an SRS transmission opportunity (i.e., the sixth resource type) located on a time domain resource whose time domain format is the first format and does not include a downlink common or broadcast signal to initiate transmission of the first SRS, the first SSB associated with the first SRS is included in SSB set 1, and the transmission power of the first SRS is determined according to the following formula: P SRS =min{P CMAX , P UL PC,SRS +offsetX}, wherein "offsetX" (i.e., the first power offset value) in the above formula may be a power offset determined based on power offset 1 and power offset 4, for example, "offsetX" in the formula = power offset 1 + power offset 4.

[0177] When the terminal selects an SRS transmission opportunity (i.e., the seventh resource type) located on a time domain resource whose time domain format is the first format and contains a downlink common or broadcast signal to initiate transmission of the first SRS, the first SSB associated with the first SRS is included in SSB set 2, and the transmission power of the first SRS is determined according to the following formula: P SRS =min{P CMAX , P UL PC,SRS +offsetY}, wherein "offsetY" (i.e., the first power offset value) in the above formula may be a power offset determined based on power offset 2 and power offset 5, for example, "offsetY" in the formula = power offset 2 + power offset 5.

[0178] The transmit power determination method provided in the embodiment of the present application may be executed by a transmit power determination device. In the embodiment of the present application, the transmit power determination device performing the transmit power determination method is used as an example to illustrate the transmit power determination device provided in the embodiment of the present application.

As shown in FIG7 , the transmit power determination apparatus 50 may include: a determination module 51 configured to, in the case of full-duplex transmission, determine the transmit power for transmitting a first SRS when the transmit power determination apparatus 50 is in a non-connected state based on a first object, wherein the first object includes at least one of the following: a resource type corresponding to the first reference signal; a reference signal set corresponding to the first reference signal; and a resource type corresponding to the first SRS.

[0180] An embodiment of the present application provides a transmission power determination device. Since, when the transmission power determination device performs full-duplex transmission, the transmission power determination device can accurately determine the transmission power of the first SRS transmitted when the transmission power determination device is in a non-connected state based on the resource type corresponding to the first reference signal, the reference signal set corresponding to the first reference signal, and at least one of the resource types corresponding to the first SRS, without having to determine it based on the TPC command sent by the network device. Therefore, it can avoid situations that affect the downlink transmission of the transmission power determination device, or it can avoid the coverage range of the SRS being small, thereby improving the reliability of the downlink transmission of the transmission power determination device, or enabling the network side device to receive the SRS. In this way, the communication performance of the transmission power determination device can be improved.
