Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a method, apparatus, terminal, and readable storage medium for determining transmit power. Background Art

[0002] Currently, in a New Radio (NR) system, when a terminal performs full-duplex transmission, if the terminal is in the connected state, the network-side device can send a Transmit Power Control (TPC) command to the terminal. Thus, the terminal can determine the transmit power of the Sounding Reference Signal (SRS) according to the TPC command, so as to ensure the coverage range of the SRS while not affecting other downlink transmissions of the terminal.

[0003] However, since the terminal may be in a non-connected state (i.e., idle or inactive), in this case, the network-side device may not be able to send a TPC command to the terminal, which may lead to inaccurate transmit power of the terminal transmitting the SRS. Therefore, it may affect other downlink transmissions of the terminal, or may result in a small coverage range of the SRS, thereby reducing the reliability of other downlink transmissions of the terminal, or causing the network-side device to be unable to receive the SRS. Thus, the communication performance of the terminal is poor. Summary of the Invention

[0022] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0023] The following will explain the terms related to the embodiments of the present application.

[0024] 1. TPC command

[0025] TPC commands can be used to compensate for channel variations caused by fast fading. Regarding the current Long Term Evolution (LTE) system, the power of the Physical Uplink Control Channel (PUCCH) can be adjusted by the TPC commands signaled in the Downlink Control Information (DCI) of the downlink allocation, while the power of the Physical Uplink Shared Channel (PUSCH) or SRS can be adjusted by the TPC commands signaled in the DCI of the uplink grant. In addition, for uplink transmissions without relevant DCI, such as

[0026] Semi-Persistent Scheduling (SPS), periodic Channel State Information (CSI), or SRS, the TPC commands can be signaled to a specific UE group by using DCI format 3 / 3A. There are two types of TPC commands for updating the uplink transmit power; one is the accumulative TPC command, and the other is the absolute TPC command. The accumulative TPC command is well-suited for fine-tuning the transmit power of the terminal by using a relatively small step size of the TPC value. On the other hand, by using a relatively large step size of the TPC value, the absolute TPC command can be used to immediately increase the transmit power of the terminal.

[0027] 2. Uplink SRS Resources

[0028] Currently, uplink beam training is supported in NR through SRS. However, in the initial access phase, since the terminal does not transmit SRS, there is no uplink beam management. The uplink beam used by the terminal when transmitting the preamble and Msg3, or MsgA, depends on the implementation method of the terminal. However, in the 4-step random access (4-step RACH) in NR, there is a requirement for the consistency of the uplink beam for transmitting Msg3 and the uplink beam of the physical uplink control channel (PUCCH) carrying the hybrid automatic repeat request-acknowledgement (HARQ-ACK) of Msg4, that is, the terminal needs to ensure that the uplink beam used for transmitting Msg3 is the same as the uplink beam of the PUCCH carrying the HARQ-ACK of Msg4. Similarly, for the 2-step random access (2-step RACH), the terminal needs to ensure that the uplink beam used for transmitting MsgA is the same as the uplink beam of the PUCCH carrying the HARQ-ACK of MsgB. In the radio resource control (RRC) connected state, the uplink beam training results based on SRS 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 the idle / inactive state. For example, the association between the Synchronization Signal, SS) / (Physical Broadcast Channel, PBCH) Block, SSB) / Channel State Information Reference Signal, CSI-RS) and SRS can be introduced so that the terminal can perform uplink beam training before cell access and determine, for example, a more suitable Physical Random Access Channel, PRACH) transmission beam to improve PRACH reception reliability. On the other hand, for example, the association between PRACH resources / MsgA resources / MsgA PUSCH resources and multiple SRS resources is introduced, so that different terminals can use different associated SRS beams to send the same PRACH preamble, improving the capacity of the PRACH. Or, for example, multiple PRACH / MsgA resources / MsgA PUSCH resources are introduced into the association with SRS, which can support the repetition of multiple 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 the inactive state, SRS resources can be configured to send SRS signals for terminal positioning in the inactive state.

[0035] Next, with reference to the accompanying drawings, the method, apparatus, terminal, and readable storage medium for determining transmission power provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0036] Figure 2 The flowchart of a method for determining transmission power provided by an embodiment of the present application is shown. As Figure 2 shown, a method for determining transmission power provided by an embodiment of the present application may include step 101 described below.

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

[0038] In some embodiments of the present application, the terminal may receive configuration information from the network-side device, where the configuration information is used to configure the terminal to send the first SRS, and according to the configuration information, determine the first SRS. Thus, when the terminal performs full-duplex transmission, the transmission power of the first SRS when the terminal is in the non-connected state can be determined according to the first object.

[0039] In the embodiments of the present application, the above-mentioned first object includes at least one of the following:

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

[0041] The set of reference signals corresponding to the first reference signal;

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

[0043] In some embodiments of the present application, the above-mentioned 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 configuration information further includes the 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 above-mentioned first reference signal may be a downlink reference signal, and the first reference signal may include at least one of the following: Synchronization Signal and PBCH block (SSB), Channel State Information Reference Signal (CSI-RS), Tracking Reference Signal (TRS), 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 above-mentioned first reference signal can be understood as: the resource type of the time domain resource and / or frequency domain resource occupied by the first reference signal.

[0048] In some embodiments of the present application, the above-mentioned first object includes the 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] The first resource type, which is used to characterize a type of time domain resource with a downlink time domain format;

[0050] The second resource type, which is used to characterize a type of time domain resource with a first time domain format.

[0051] In some embodiments of the present application, the above time domain format may also be a time domain type. Among them, the time domain format (time domain type) corresponding to the first reference signal may be indicated by a full-duplex sub-band configuration or a full-duplex sub-band indication. For example, the time domain format indicated by TDD-UL-DL-Configuration, such as downlink (DL), uplink (UL), flexible; or, the time domain type indicated by xdd-UL-DL-Configuration, such as full downlink (FullDL), full uplink (Full UL), sub-band full duplex (SBFD)x; or, the frequency domain format indicated by a full-duplex sub-band configuration, such as a downlink sub-band (DL Subband), an uplink sub-band (ULSubband), a guard band, a downlink bandwidth part (DL BWP), an uplink bandwidth part (UL BWP).

[0052] In an embodiment of the present application, the above 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, both an uplink sub-band and a downlink sub-band are included simultaneously on the entire bandwidth corresponding to the time domain resources of the first format.

[0054] Thus, it can be seen that the terminal can determine the transmission power of the first SRS from different transmission powers when the resource types included in the resource type corresponding to the first reference signal are different, 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. Thus, when performing full-duplex transmission, that is, when receiving downlink transmission (for example, downlink transmission received by the terminal from a 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 ensured; and, when the terminal performs half-duplex transmission subsequently, that is, when only sending the first SRS according to the determined transmission power of the first SRS, the coverage range of the first SRS can be ensured.

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

[0056] The third resource type is used to represent a type of time-domain resource whose time-domain format is the first format and the interval between the corresponding uplink sub-band and the corresponding downlink sub-band 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 the interval between the corresponding uplink sub-band and the corresponding downlink sub-band is less than or equal to a second preset value.

[0058] It can be understood that the above-mentioned third resource type is used to represent a type of time-domain resource whose corresponding frequency-domain resource of the time-domain resource includes an uplink sub-band and a downlink sub-band, and the interval between the corresponding uplink sub-band and the corresponding downlink sub-band is greater than or equal to a first preset value; the above-mentioned fourth resource type is used to represent a type of time-domain resource whose corresponding frequency-domain resource of the time-domain resource includes an uplink sub-band and a downlink sub-band, and the interval between the corresponding uplink sub-band and the corresponding downlink sub-band 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] Thus, it can be seen that since the second resource type can also be divided into a third resource type and a fourth resource type, so that in the case where 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. Therefore, the accuracy of the determined transmission power of the first SRS can be further improved.

[0061] In some embodiments of the present application, the reference signal set corresponding to the first reference signal can 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 the 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] The first reference signal set, which includes reference signals whose time-domain format of the corresponding time-domain resource is downlink;

[0064] The second reference signal set, which includes reference signals whose time-domain format of the corresponding time-domain resource is the first format;

[0065] The third reference signal set, which includes reference signals whose time-domain format of the corresponding time-domain resource is the first format and the interval between the corresponding uplink sub-band and the corresponding downlink sub-band is greater than or equal to a third preset value;

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

[0067] In the embodiments of the present application, the above-mentioned 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 subband and a downlink subband.

[0068] In some embodiments of the present application, the above-mentioned third preset value and the fourth preset value may be the same or different, and the above-mentioned 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 set of reference signals is the above-mentioned first resource type, the resource type corresponding to the reference signals included in the second set of reference signals is the above-mentioned second resource type, the resource type corresponding to the reference signals included in the third set of reference signals is the above-mentioned third resource type, and the resource type corresponding to the reference signals included in the fourth set of reference signals is the above-mentioned fourth resource type.

[0070] Thus, it can be seen that the terminal can determine the transmission power of the first SRS from different transmission powers when the set of reference signals corresponding to the first reference signal includes different sets of reference signals, 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. Thus, when performing full-duplex transmission, that is, when receiving downlink transmission and transmitting the first SRS according to the determined transmission power of the first SRS, the interference to the downlink transmission caused by transmitting the first SRS can be reduced, thereby improving the performance of the downlink transmission, and the coverage range of the first SRS can be ensured; moreover, when the terminal performs half-duplex transmission subsequently, that is, when only transmitting the first SRS according to the determined transmission power of the first SRS, the coverage range of the first SRS can be ensured.

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

[0072] A fifth resource type, which is used to represent a type of time domain resources with a downlink time domain format;

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

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

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

[0076] In the embodiments 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, a broadcast signal. Wherein, the broadcast signal may include at least one of the following: SSB, System Information Block (SIB), Master Information Block (MIB), Paging signal, etc.

[0078] Thus, it can be seen that the terminal can determine the transmission power of the first SRS from different transmission powers when the resource types included in the resource type corresponding to the first SRS are different, 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. Thus, when performing full-duplex transmission, that is, when receiving downlink transmission and transmitting the first SRS according to the determined transmission power of the first SRS, the interference to the downlink transmission caused by transmitting the first SRS can be reduced, thereby improving the performance of the downlink transmission, and the coverage range of the first SRS can be ensured; moreover, when the terminal performs half-duplex transmission subsequently, that is, when only transmitting the first SRS according to the determined transmission power of the first SRS, the coverage range of the first SRS can be ensured.

[0079] An embodiment of the present application provides a method for determining transmission power. When a terminal performs full-duplex transmission, it can determine the transmission power of transmitting a first SRS when the terminal is in a non-connected state according to a first object, where 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 transmission power of transmitting the first SRS when the terminal is in a non-connected state according to 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 determining it according to a TPC command sent by a network device, it is possible to avoid a situation that affects the terminal's downlink transmission, or 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. In this way, the communication performance of the terminal can be improved.

[0080] The following will illustrate a specific solution for the terminal to determine the transmission power of the first SRS by way of examples.

[0081] Example 1

[0082] In some embodiments of the present application, the above-mentioned first object includes at least one of the following: a resource type corresponding to a first reference signal, a reference signal set corresponding to the first reference signal. Optionally, combined with Figure 2 , as Figure 3 shown, the above-mentioned step 101 can be specifically implemented by the following step 101a and step 101b.

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

[0084] In some embodiments of the present application, the above-mentioned 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 transmission power;

[0091] Path loss parameter.

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

[0093] In some embodiments of the present application, the above path loss parameter may include a path loss estimated value, a reference signal corresponding to the path loss estimation, and the like.

[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 Figure 3 , such as Figure 4 shown, before the above step 101a, the transmission power determination method provided by the embodiments of the present application may further include the following step 201, and the above step 101a may be specifically implemented by the following step 101a1.

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

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

[0099] In some embodiments of the present application, each of the above 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 receive 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 above power offset value can be a positive number, a negative number, or 0.

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

[0110] In some embodiments of the present application, the terminal can 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 the resource type corresponding to the first reference signal and the reference signal set corresponding to the first reference signal.

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

[0113] Thus, 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 accurately determine the target power parameter directly according to 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 the transmit power for transmitting the first SRS when the terminal is in a non-connected state according to the target power parameter.

[0115] In some embodiments of the present application, when the target power parameter includes at least one of a target received power, a path loss compensation factor, a power compensation factor, a maximum transmit power, and a path loss parameter, the terminal may determine the transmit power corresponding to the target received power as the transmit 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 according to the power offset value. Optionally, the above target power parameter includes a first power offset value. The above step 101b may be specifically implemented by the following steps 101b1 and 101b2.

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

[0118] In some embodiments of the present application, the terminal may first calculate a third transmit power using uplink power control, 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 the transmit power for transmitting the first SRS when the terminal is in a disconnected state according to the first transmit power and the second transmit power.

[0120] In the embodiments of the present application, the above second transmit power is the maximum transmit power of the terminal.

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

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

[0123] It can be understood that the terminal may use a first algorithm to calculate the transmit power for transmitting the first SRS when the terminal is in a disconnected state according to the first power offset value.

[0124] Among them, the first algorithm may specifically be:

[0125] P SRS =min{P CMAX ,P UL_PC,SRS +offset};

[0126] Among them, the P SRS is the transmit power for transmitting the first SRS, the P CMAX is the maximum transmit power of the terminal (i.e., the second transmit power), PUL_PC,SRS P is the third transmission power calculated by the terminal using uplink power control, and offset is the first power offset value.

[0127] It should be noted that for the description of determining the maximum transmission power of the terminal, reference can be made to the specific description in the related art, and the embodiments of the present application will not elaborate herein.

[0128] In some examples, the terminal can adopt a second algorithm to calculate the above-mentioned third transmission power P UL_PC,SRS 。

[0129] Among them, the second algorithm can specifically be:

[0130] P = min{P CMAX , [p 0 (j) + α(k) * PL(q) ± f(l) + [10lgM + Δ]};

[0131] Among them, P CMAX is the configured transmission power of the terminal on this uplink carrier (the maximum transmission power allowed by this uplink carrier), p 0 (j) is the open-loop receiver power target value, which is related to the target signal-to-noise interference ratio (SINR) and interference intensity expected by the network-side device. The larger the value of this target SINR, the higher the usually uplink transmission power, and the higher the SINR of the receiver. PL(q) is the path loss estimation, and q is an index, and one is selected from a group of path loss estimation values maintained by the terminal. For the same terminal, different reference signals of the same serving cell may also experience different path losses. For example, the SSB beam width is relatively wide, the beamforming gain is low, and the path loss estimation is large; while the CSI-RS beam is relatively narrow, the beamforming gain is high, and the path loss estimation is small. Therefore, the same terminal needs to maintain multiple path loss estimation values and take out a certain path loss estimation value according to the index configured or indicated by the network side to calculate the transmission power. The closed-loop part f(l) is the l-th power control offset (adjustment) state value, which can quickly adjust the transmission power for a certain transmission of a certain terminal. The adjustment basis is the effect of the previous transmission, and the adjustment information is quickly adjusted through physical layer signaling (DCI) (the relevant parameters are still quasi-statically configured by RRC high-layer signaling). Such adjustment is called closed-loop adjustment. For example, if the network-side device finds that the transmission power of a certain terminal is too high, the network-side device 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 DCI is called TPC and is denoted as δ(l).

[0132] 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 the first SRS when the terminal is in the non-connected state according to the maximum transmission power of the terminal and the first transmission power, that is, the determined transmission power of the first SRS takes into account the maximum transmission power of the terminal. Therefore, the situation where the determined transmission power of the first SRS is greater than the maximum transmission power of the terminal can be avoided.

[0133] In some embodiments of the present application, when the target power parameter includes a TPC command, the terminal can determine the transmission power indicated by the TPC command as the transmission power of the first SRS.

[0134] It can be seen that since the terminal can directly obtain the corresponding target power parameter according to at least one of the resource type corresponding to the first reference signal and the reference signal set corresponding to the first reference signal, the terminal can accurately determine the transmission power of the first SRS according to the target power parameter.

[0135] For example, assume that the target power parameter includes a first power offset value and the first reference signal is an SSB. Then the terminal can first receive the first power configuration information related to the SSB. The first power configuration information includes the power offset value (power offset) corresponding to SSB set 1 (for example, the first reference signal set in the above embodiment), such as power offset1 = X, and the power offset value (power offset) corresponding to SSB set 2 (for example, the second reference signal set in the above embodiment), such as power offset 2 = Y.

[0136] Thus, when the terminal operates in the full-duplex transmission mode and initiates the transmission of the first SRS in the Idle / inactive state, it can obtain the first power offset value power offset 1 (i.e., X) according to the SSB set (such as SSB set 1) corresponding to the first SSB associated with the first SRS, and use the first algorithm to calculate the transmission power of the first SRS according to power offset 1; where the first algorithm is: P SRS = min{P CMAX , P UL_PC,SRS + offset 1}, this P SRS is the transmission power of the first SRS, this P CMAX is the maximum transmission power of the terminal (i.e., the second transmission power), P UL_PC,SRS is the third transmission power calculated by the terminal using uplink power control, and offset 1 is the above power offset 1 (i.e., X). Or,

[0137] When the terminal operates in the full-duplex transmission mode and is in the Idle / inactive state, the terminal initiates the transmission of the first SRS. It can obtain the first power offset value power offset 2 (i.e., Y) according to the SSB set corresponding to the first SSB associated with the first SRS (such as SSB set 2), and use the first algorithm to calculate the transmission power of the first SRS based on power offset 2; where, the first algorithm is: P SRS = min{P CMAX , P UL PC,SRS + offset 2}, and this P SRS is the transmission power of the first SRS, this P CMAX is the maximum transmission power of the terminal (i.e., the second transmission power), P UL_PC,SRS is the third transmission power calculated by the terminal using uplink power control, and offset 2 is the above-mentioned power offset 2 (i.e., Y).

[0138] Example two

[0139] In some embodiments of the present application, the above first object includes the resource type corresponding to the first SRS. Optionally, in combination Figure 2 , as Figure 5 shown, step 101 above can be specifically implemented by the following step 101c and step 101d.

[0140] Step 101c: When the terminal performs full-duplex transmission, obtain the target power parameter according to the resource type corresponding to the first SRS.

[0141] In some embodiments of the present application, the above target power parameter includes at least one of the following:

[0142] Target received power

[0143] Power offset value

[0144] Path loss compensation factor

[0145] Transmission power control TPC command

[0146] Power compensation factor

[0147] Maximum transmission power

[0148] Path loss parameter

[0149] 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 SRS, so that the terminal can directly determine the power parameters corresponding to the resource type corresponding to the first SRS as the target power parameters.

[0150] In some embodiments of the present application, in combination with Figure 5 , such as Figure 6 shown, before the above step 101c, the transmit power determination method provided by the embodiments of the present application may further include the following step 301, and the above step 101c may be specifically implemented by the following step 101c1.

[0151] Step 301: The terminal receives second power configuration information related to the first SRS.

[0152] In the embodiments of the present application, the above second power configuration information includes at least one power parameter corresponding to at least one resource type.

[0153] In some embodiments of the present application, each of the at least one power parameter includes at least one of the following:

[0154] Target receive power;

[0155] Power offset value;

[0156] Path loss compensation factor;

[0157] TPC command;

[0158] Power compensation factor;

[0159] Maximum transmit power;

[0160] Path loss parameter.

[0161] In some embodiments of the present application, the terminal may receive the second power configuration information from the network-side device.

[0162] Step 101c1: The terminal determines, from the at least one power parameter, the target power parameter corresponding to the resource type corresponding to the first SRS.

[0163] In some embodiments of the present application, the terminal may first determine, from the at least one resource type, a resource type that is the same as the resource type corresponding to the first SRS, and then determine the power parameter corresponding to the one resource type as the target power parameter.

[0164] Thus, it can be seen that 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 and accurately determine the target power parameter according to the resource type corresponding to the first SRS.

[0165] Step 101d: The terminal determines the transmission power of the first SRS when the terminal is in the disconnected state according to the target power parameter.

[0166] It should be noted that for the description of the terminal determining the transmission power of the first SRS when the terminal is in the disconnected state according to the target power parameter, reference can be made to the specific description in the above embodiments, and the embodiments of the present application will not elaborate here.

[0167] Thus, it can be seen that 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 transmission power of the first SRS according to this target power parameter.

[0168] In some embodiments of the present application, the above target power parameter includes a first power offset value. The above step 101d can be specifically implemented by the following step 101d1 and step 101d2.

[0169] Step 101d1: The terminal determines a first transmission power based on the first power offset value.

[0170] Step 101d2: The terminal determines the transmission power of the first SRS when the terminal is in the disconnected state according to the first transmission power and the second transmission power.

[0171] In the embodiments of the present application, the above second transmission power is the maximum transmission power of the terminal.

[0172] Thus, 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 the first SRS when the terminal is in the disconnected state according to the maximum transmission power of the terminal and this first transmission power, that is, the determined transmission power of the first SRS takes into account the maximum transmission power of the terminal, so the situation where the determined transmission power of the first SRS is greater than the maximum transmission power of the terminal can be avoided.

[0173] For example, assume that the target power parameter includes a power offset value and the first reference signal is an SSB. Then, the terminal can first receive the second power configuration information related to the first SRS. The second power configuration information includes the power offset values corresponding to type 1 (such as the fifth resource type in the above embodiment), for example, power offset 1 = 0; the power offset values corresponding to type 2 (such as the sixth resource type in the above embodiment), for example, power offset 2 = X; the power offset values corresponding to type 3 (such as the seventh resource type in the above embodiment), for example, power offset 3 = Y; and the power offset values corresponding to type 4 (such as the eighth resource type in the above embodiment), for example, power offset 4 = Z.

[0174] Thus, when the terminal operates in the full-duplex transmission mode and is in the Idle / inactive state, when the terminal initiates the transmission of the first SRS, it can obtain the first power offset value power offset 1 (i.e., 0) according to the resource type corresponding to the first SRS (such as type 1), and use the first algorithm to calculate the transmission power of the first SRS based on power offset 1. Among them, the first algorithm is: P SRS = min{P CMAX , P UL_PC,SRS}, where this P SRS is the transmission power of the first SRS, this P CMAX is the maximum transmission power of the terminal (i.e., the second transmission power), and P UL_PC,SRS is the third transmission 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. Or,

[0175] When the terminal operates in the full-duplex transmission mode and is in the Idle / inactive state, when the terminal initiates the transmission of the first SRS, it can obtain the first power offset value power offset 2 (i.e., X) according to the resource type corresponding to the first SRS (such as type 2), and use the first algorithm to calculate the transmission power of the first SRS based on power offset 2. Among them, the first algorithm is: P SRS = min{P CMAX , P UL PC,SRS + offset2}, where this P SRS is the transmission power of the first SRS, this P CMAX is the maximum transmission power of the terminal (i.e., the second transmission power), PUL_PC,SRS The third transmission power calculated by the terminal using uplink power control, where the offset2 is the above-mentioned power offset 2 (i.e., X). Or,

[0176] When the terminal operates in the full-duplex transmission mode and is in the Idle / inactive state, the terminal initiates the transmission of the first SRS. It can obtain the power offset 3 (i.e., Y) according to the resource type corresponding to the first SRS (such as type 3), and use the first algorithm to calculate the transmission power of the first SRS based on the power offset 3; where the first algorithm is: P SRS = min{P CMAX , P UL PC,SRS + offset3}, where the P SRS is the transmission power of the first SRS, the P CMAX is the maximum transmission power of the terminal (i.e., the second transmission power), P UL_PC,SRS is the third transmission power calculated by the terminal using uplink power control, and the offset3 is the above-mentioned power offset 3 (i.e., Y). Or,

[0177] When the terminal operates in the full-duplex transmission mode and is in the Idle / inactive state, the terminal initiates the transmission of the first SRS. It can obtain the power offset 4 (i.e., Z) according to the resource type corresponding to the first SRS (such as type 4), and use the first algorithm to calculate the transmission power of the first SRS based on the power offset 4; where the first algorithm is: P SRS = min{P CMAX , P UL PC,SRS + offset 4}, where the P SRS is the transmission power of the first SRS, the P CMAX is the maximum transmission power of the terminal (i.e., the second transmission power), P UL_PC,SRS is the third transmission power calculated by the terminal using uplink power control, and the offset4 is the above-mentioned power offset 4 (i.e., Z).

[0178] Example 3.

[0179] Assume that the target power parameter includes a first power offset value, and the first reference signal resource is an SSB. Then the terminal can first receive the first power configuration information and the second power configuration information related to the SSB. The first power configuration includes the power offset values (power offset) corresponding to SSB set 1 (such as the first reference signal set in the above embodiments), for example, poweroffset 1, and the power offset values (power offset) corresponding to SSB set 2 (such as the second reference signal set in the above embodiments), for example, power offset 2. The second power configuration information includes the power offset values (power offset) corresponding to type 1 (such as the fifth resource type in the above embodiments), for example, power offset 1, the power offset values (power offset) corresponding to type 2 (such as the sixth resource type in the above embodiments), for example, power offset 2, the power offset values (power offset) corresponding to type 3 (such as the seventh resource type in the above embodiments), for example, poweroffset3, and the power offset values (power offset) corresponding to type 4 (such as the eighth resource type in the above embodiments), for example, power offset 4.

[0180] When the terminal selects an SRS transmission opportunity (seventh resource type) on a time-domain resource with a UL time-domain format to initiate the transmission of the first SRS, and the first SSB associated with the first SRS is included in SSB set 1, the transmission power of the first SRS is determined according to the following formula: P SRS = min{P CMAX , P UL_PC,SRS + offset1}, where P UL_PC,SRS is the third transmission power determined for uplink power control, P CMAX represents the maximum transmission power of the terminal (i.e., the second transmission power), and offset1 is the first power offset value power offset 3. Or,

[0181] When the terminal selects an SRS transmission opportunity (i.e., the sixth resource type) on a time-domain resource in the first format and not including downlink common or broadcast signals to initiate the transmission of the first SRS, and the first SSB associated with the first SRS is included in SSB set 1, the transmission power of the first SRS is determined according to the following formula: P SRS = min{P CMAX , P UL PC,SRS+ offsetX}, where the "offsetX" (i.e., the first power offset value) in the above formula can be a power offset determined based on power offest1 and power offset 4. For example, "offsetX" in the formula = power offest 1 + power offest 4.

[0182] When the terminal selects to initiate the transmission of the first SRS at the SRS transmission opportunity (i.e., the seventh resource type) located in the time domain resource with the first format and including the downlink common or broadcast signal, the first SSB associated with the first SRS is included in the 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}, where the "offsetY" (i.e., the first power offset value) in the above formula can be a power offset determined based on power offest 2 and power offset 5. For example, "offsetY" in the formula = power offest 2 + power offest 5.

[0183] In the method for determining the transmission power provided by the embodiments of the present application, the execution subject can be a transmission power determination device. In the embodiments of the present application, taking the transmission power determination device as an example to execute the method for determining the transmission power, the transmission power determination device provided by the embodiments of the present application is described.

As Figure 7 shown, the transmission power determination device 50 may include: a determination module 51, configured to, in the case of full-duplex transmission, determine the transmission power of transmitting the first SRS when the transmission power determination device 50 is in a non-connected state according to the first object, where the first object includes at least one of the following: the resource type corresponding to the first reference signal; the reference signal set corresponding to the first reference signal; the resource type corresponding to the first SRS.

[0185] An embodiment of the present application provides a transmission power determination device. When the transmission power determination device performs full-duplex transmission, the transmission power determination device can accurately determine the transmission power for transmitting the first SRS when it is in a non-connected state according to 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 determining it according to the TPC command sent by the network device. Therefore, it is possible to avoid a situation that affects the downlink transmission of the transmission power determination device, or to avoid a small coverage range of the SRS, 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.

Wherein, the above-mentioned 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.
