Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method, device, apparatus and storage medium for determining SRS transmission power. Background Technology

[0002] In the 3rd Generation Partnership Project (3GPP) New Radio (NR) system, in order to better acquire downlink channel state information (DL CSI), the terminal can report its supported Sounding Reference Signal (SRS) antenna switching capabilities (in the NR system protocol, this can be reported through terminal capability signaling srs-TxSwitch, etc.). The antenna switching capabilities reported by the terminal are used to indicate the xTyR capabilities supported by the terminal (where xTyR can be one or more of 1T1R, 1T2R, 1T4R, 2T2R, 2T4R, 1T6R, 1T8R, 2T6R, 2T8R, 4T6R, and 4T8R, and its candidate values ​​may continue to increase as the protocol is further improved).

[0003] Network devices (e.g., base stations) can configure one or more SRS resource sets for DL ​​CSI acquisition for a terminal based on the antenna switching capabilities reported by the terminal. Each SRS resource set includes one or more SRS resources. In the current system, the base station can configure corresponding power control parameters for each SRS resource set. The terminal uses the power control parameters corresponding to the SRS resource set to determine the transmission power corresponding to the SRS resource, and then distributes this transmission power evenly across all antenna ports configured for the SRS resource. In the NR system Rel-16 protocol, the transmission power corresponding to the SRS resource is calculated using the following formula: the transmission capacity of the SRS cannot exceed the maximum transmit power P. CMAX,f,c (i) (For an explanation of each parameter, please refer to section 7.3.1 of 3GPP protocol TS38.213 V16.7.0 (2021-09):

[0004]

[0005] Accordingly, when determining the DL CSI quality, the base station compares the relative channel quality between downlink receiving antennas based on the same transmit power corresponding to each SRS resource, in order to guide downlink scheduling.

[0006] However, for terminals with antenna switching capabilities such as 4T6R or 4T8R, the existing SRS power control mechanism may not work well due to the structure of their RF chain. For example, for a terminal supporting 4T6R, if all four RF chains are 17dBm power amplifiers (PAs), the maximum output power corresponding to the terminal's power level is 23dBm. If the base station configures an SRS resource set with usage "antennaSwitching" for the terminal, including one 4-port SRS resource and one 2-port SRS resource, then according to the existing SRS power control mechanism, when the SRS transmission power calculated according to the power control parameters has not reached the maximum transmit power, the total transmit power of the two SRS resources is the same; when the SRS transmission power calculated according to the power control parameters reaches the maximum transmit power P... CMAX,f,c When (i) = 23dBm, for a 4-port SRS resource, the transmit power of each port should be one-quarter of 23dBm, i.e., 17dBm. For a 2-port SRS resource, the transmit power of each port should be half of 23dBm, i.e., 20dBm. Since the terminal's PA cannot reach 20dBm, the terminal can only transmit at 17dBm to each antenna port of the 2-port SRS resource. However, the base station always determines the DL CSI quality based on the total transmit power of the 2-port SRS resource being the same as the total transmit power of the 4-port SRS resource. This will cause the base station to make an incorrect prediction of the DL CSI quality when the SRS transmission power calculated by the terminal based on the power control parameters is near the maximum transmit power, thus failing to perform optimal downlink scheduling.

[0153] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0154] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0155] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0156] Figure 1 This is one of the flowcharts illustrating the SRS transmission power determination method provided in this application embodiment. This method can be applied to terminals, such as... Figure 1 As shown, the method includes the following steps:

[0157] Step 100: Determine the transmission power of the antenna port corresponding to the target SRS based on the configuration of each SRS resource in one or more SRS resource sets. The target SRS is the SRS corresponding to the target SRS resource in one or more SRS resource sets.

[0158] Specifically, network devices (such as base stations) can configure one or more SRS resource sets for terminals, each SRS resource set including one or more SRS resources.

[0159] In existing SRS power control mechanisms, the terminal always determines the transmission power of the antenna port configured for each SRS resource based on its own configuration. This may lead to inconsistencies between the network device's understanding of the relative transmission power of different SRSs and the actual transmission power of the SRS sent by the terminal in certain RF chain structures, resulting in incorrect judgments. For example, when SRS resources are used for DL ​​CSI acquisition, it will cause the network device to make incorrect predictions about the DL CSI quality, thus failing to perform optimal downlink scheduling.

[0160] To avoid the above problems, in this embodiment of the application, the terminal can determine the transmission power of the antenna port corresponding to the target SRS based on the configuration of each SRS resource in one or more SRS resource sets. The target SRS is the SRS corresponding to the target SRS resource in one or more SRS resource sets. The transmission power of the antenna port corresponding to the target SRS can be understood as the transmission power corresponding to the antenna port configured for the target SRS resource.

[0161] For example, if a network device configures an SRS resource set for a terminal, the terminal determines the transmission power of the antenna port corresponding to the target SRS based on the configuration of all SRS resources in this SRS resource set; or, if a network device configures multiple SRS resource sets for a terminal, the terminal determines the transmission power of the antenna port corresponding to the target SRS based on the configuration of all SRS resources in these multiple SRS resource sets.

[0162] Therefore, regardless of the RF chain structure of the terminal, the terminal can guarantee the relative power relationship between different SRS resources, so that the network device's understanding of the SRS transmission power can be consistent with the actual transmission power of the SRS sent by the terminal.

[0163] It should be understood that the technical solutions of the embodiments of this application are not only applicable to SRS resources for DL ​​CSI acquisition, but also to SRS resources for other purposes, and are not specifically limited herein. For example, SRS resources may be SRS resources for a certain purpose in a Multi-Transmit Receive Point (M-TRP) scenario, or SRS resources for uplink CSI acquisition (e.g., SRS resources in a set of SRS resources where the higher-layer parameter usage is configured as "codebook", or SRS resources in a set of SRS resources where the higher-layer parameter usage is configured as "nonCodebook"), or SRS resources for interference measurement, or SRS resources for beam management, etc. For the convenience of subsequent discussion, each embodiment of this application will be described using SRS resources for DL ​​CSI acquisition as an example.

[0164] Optionally, each SRS resource in one or more SRS resource sets can be an SRS resource used for the same purpose. For example, each SRS resource in one or more SRS resource sets can be an SRS resource used for DL ​​CSI acquisition, such as an SRS resource whose higher-layer signaling usage is configured as "antennaSwitching".

[0165] Optionally, each SRS resource in one or more SRS resource sets can be an SRS resource used for the same purpose and configured with the same time domain type. For example, each SRS resource in one or more SRS resource sets can be an SRS resource configured with the same time domain type among SRS resources used for DLCSI acquisition. Some examples of time domain types include: periodic, aperiodic, and semi-persistent. For example, an SRS resource whose higher-layer signaling resourceType is configured as "aperiodic" and whose higher-layer signaling usage is configured as "antennaSwitching". Another example is an SRS resource whose higher-layer signaling resourceType is configured as "periodic" and whose higher-layer signaling usage is configured as "antennaSwitching". Yet another example is an SRS resource whose higher-layer signaling resourceType is configured as "semi-persistent" and whose higher-layer signaling usage is configured as "antennaSwitching".

[0166] Optionally, each SRS resource in one or more SRS resource sets can be a specific type of SRS resource. For example, each SRS resource in one or more SRS resource sets is an SRS resource used for a specific SRS transmission port switching pattern (in some embodiments, it can be described as "SRS antenna switching pattern", "antenna switching pattern obtained by DL CSI", "SRS antenna switching mode", "antenna switching mode obtained by DL CSI", etc.), for example, an SRS resource for which the higher-layer signaling usage is configured as "antennaSwitching" and the SRS transmission port switching pattern is 4T6R.

[0167] Step 101: Send the target SRS according to the transmission power.

[0168] Specifically, after determining the transmission power of the antenna port corresponding to the target SRS based on the configuration of each SRS resource in one or more SRS resource sets, the terminal can send the target SRS to the network device according to the determined transmission power of the antenna port corresponding to the target SRS.

[0169] The SRS transmission power determination method provided in this application embodiment allows the terminal to determine the transmission power of the antenna port corresponding to the target SRS based on the configuration of each SRS resource in one or more SRS resource sets. Thus, regardless of the RFchain structure of the terminal, the terminal can ensure the relative power relationship between different SRS resources, so that the network device's understanding of the SRS transmission power can be consistent with the actual transmission power of the SRS sent by the terminal.

[0170] Optionally, the transmission power of the antenna port corresponding to the target SRS is determined based on the configuration of each SRS resource in one or more SRS resource sets, including:

[0171] The transmission power of the antenna port corresponding to the target SRS is determined based on the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets.

[0172] Specifically, in this embodiment, the terminal can determine the transmission power of the antenna port corresponding to the target SRS based on the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets. For example, if the network device configures an SRS resource set for the terminal, the terminal determines the transmission power of the antenna port corresponding to the target SRS based on the number of antenna ports configured for each SRS resource in this SRS resource set; or, for another example, if the network device configures multiple SRS resource sets for the terminal, the terminal determines the transmission power of the antenna port corresponding to the target SRS based on the number of antenna ports configured for each SRS resource in these multiple SRS resource sets.

[0173] Optionally, the transmission power of the antenna port corresponding to the target SRS is determined based on the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets, including:

[0174] Based on the number of antenna ports in the first antenna, determine the transmission power of the antenna port corresponding to the target SRS;

[0175] Wherein, the first antenna port number is the maximum value among the antenna port numbers corresponding to each SRS resource in one or more SRS resource sets, or the first antenna port number is the minimum value among the antenna port numbers corresponding to each SRS resource in one or more SRS resource sets.

[0176] Specifically, in this embodiment of the application, the terminal can determine the maximum or minimum value of each antenna port number, i.e., the first antenna port number, based on the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets configured by the network device, and determine the transmission power of the antenna port corresponding to the target SRS based on the first antenna port number.

[0177] Optionally, the transmission power of the antenna port corresponding to the target SRS is determined based on the number of first antenna ports, including:

[0178] The first transmission power corresponding to the target SRS is evenly divided using the number of first antenna ports, and the result of the equalization is taken as the transmission power of the antenna port corresponding to the target SRS; or,

[0179] Divide the first transmission power corresponding to the target SRS by the number of first antenna ports, and use the result of the division as the transmission power of the antenna port corresponding to the target SRS.

[0180] Specifically, in this embodiment, the terminal can first determine the first transmission power corresponding to the target SRS, and then divide the first transmission power equally using the number of first antenna ports, using the result of the division as the transmission power of the antenna port corresponding to the target SRS; or, the terminal can divide the first transmission power corresponding to the target SRS by the number of first antenna ports, and use the result of the division as the transmission power of the antenna port corresponding to the target SRS. For example, if the terminal determines that the first transmission power corresponding to the target SRS is P1, the number of antenna ports corresponding to the target SRS is 2, and the number of first antenna ports is 4, then (1 / 4)*P1 can be used as the transmission power of each antenna port corresponding to the target SRS.

[0181] Optionally, the first transmission power can be determined based on one or more of the following:

[0182] (1) Power control parameters corresponding to the target SRS resource. The power control parameters corresponding to the target SRS resource can be understood as the power control parameters corresponding to the SRS resource set to which the target SRS resource is located. The power control parameters may include one or more of the following: path loss reference signal parameters; target received power parameters; partial path loss compensation parameters; closed-loop power control parameters; and open-loop power control parameters.

[0185] (4) Target received power corresponding to the target SRS resource. The target received power corresponding to the target SRS resource can be understood as the target received power corresponding to the set of SRS resources to which the target SRS resource is located.

[0186] (5) Partial road loss compensation factor corresponding to the target SRS resource. The partial road loss compensation factor corresponding to the target SRS resource can be understood as the partial road loss compensation factor corresponding to the SRS resource set to which the target SRS resource is located.

The spatial relation Info corresponding to the target SRS resource can be understood as the spatial relation Info corresponding to the SRS resource set to which the target SRS resource is located. For example, it can be the transmission spatial relation Info indicated by the Transmission Configuration Indication (TCI) state corresponding to the target SRS resource or SRS resource set; for example, it can be the Quasi-Co-Location (QCL) parameter corresponding to the target SRS resource or SRS resource set.

[0189] (8) The maximum output power of the terminal.

[0190] For example, the first transmission power can be the transmission power P corresponding to the SRS, calculated using the following formula based on the power control parameters. SRS,b,f,c (i,q s (For an explanation of the parameters in this formula, please refer to section 7.3.1 of 3GPP protocol TS38.213 V16.7.0 (2021-09):)

[0191]

[0192] Optionally, the transmission power of the antenna port corresponding to the target SRS is determined based on the number of first antenna ports, including:

[0193] Based on the first transmission power and the first coefficient corresponding to the target SRS, determine the transmission power of the antenna port corresponding to the target SRS;

[0197] The first transmission power is scaled using a first coefficient, and the scaled transmission power is evenly distributed across the antenna port corresponding to the target SRS. The result of the even distribution is taken as the transmission power of the antenna port corresponding to the target SRS.

[0198] Specifically, the terminal determines the transmission power of the antenna port corresponding to the target SRS based on the first transmission power and the first coefficient. This can be achieved by scaling the first transmission power using the first coefficient, then evenly distributing the scaled transmission power across the antenna ports corresponding to the target SRS, and finally using the result as the transmission power of each antenna port corresponding to the target SRS. For example, if the terminal determines that the first transmission power corresponding to the target SRS is P1, the number of antenna ports corresponding to the target SRS is 2, and the first coefficient is 1 / 2, then the terminal can scale the first transmission power P1 using the first coefficient 1 / 2 to obtain the scaled transmission power (1 / 2)*P1. Then, it can evenly distribute (1 / 2)*P1 across the antenna ports corresponding to the target SRS by dividing (1 / 2)*P1 by the number of antenna ports corresponding to the target SRS (2), and use the result (1 / 4)*P1 as the transmission power of each antenna port corresponding to the target SRS.

[0199] Optionally, the transmission power of the antenna port corresponding to the target SRS is determined based on the number of first antenna ports, including:

[0200] The second transmission power corresponding to the target SRS is determined based on the first coefficient, and the transmission power of the antenna port corresponding to the target SRS is determined based on the second transmission power.

[0201] The first coefficient is determined based on the number of antenna ports corresponding to the target SRS and the number of first antenna ports.

[0202] Specifically, in this embodiment of the application, the terminal can first determine the second transmission power corresponding to the target SRS based on the first coefficient, and then determine the transmission power of the antenna port corresponding to the target SRS based on the second transmission power.

[0203] Optionally, the second transmission power can be determined based on the first coefficient and one or more of the following:

[0204] (1) Power control parameters corresponding to the target SRS resource. The power control parameters corresponding to the target SRS resource can be understood as the power control parameters corresponding to the SRS resource set to which the target SRS resource is located.

[0210] (7) Spatial Relation Info corresponding to the target SRS resource. The spatial relation Info corresponding to the target SRS resource can be understood as the spatial relation Info corresponding to the SRS resource set to which the target SRS resource is located. For example, it can be the transmission spatial relation Info indicated by the Transmission Configuration Indication (TCI) state corresponding to the target SRS resource or SRS resource set; for example, it can be the Quasi-Co-Location (QCL) parameter corresponding to the target SRS resource or SRS resource set.

[0211] (8) The maximum output power of the terminal. For example, the second transmission power can be the transmission power P' corresponding to the SRS, calculated using the following formula based on the first coefficient and power control parameters. SRS,b,f,c (i,q s (For an explanation of the parameters in this formula, please refer to section 7.3.1 of 3GPP protocol TS38.213 V16.7.0 (2021-09), where k1 represents the first coefficient):

[0213] The second transmission power is evenly distributed across the antenna port corresponding to the target SRS, and the result of the even distribution is taken as the transmission power of the antenna port corresponding to the target SRS.

[0214] Specifically, the terminal determines the transmission power of the antenna port corresponding to the target SRS based on the second transmission power corresponding to the target SRS. This can be achieved by equally dividing the second transmission power across the antenna ports corresponding to the target SRS, and then using the result of the equalization as the transmission power of the antenna port corresponding to the target SRS. For example, if the terminal determines that the second transmission power corresponding to the target SRS is P2 and the number of antenna ports corresponding to the target SRS is 2, then the terminal can equally divide the second transmission power P2 across the antenna ports corresponding to the target SRS, that is, divide P2 by the number of antenna ports corresponding to the target SRS, 2, and use the result (1 / 2)*P2 as the transmission power of each antenna port corresponding to the target SRS.

[0217] If the configuration of each SRS resource in one or more SRS resource sets meets the first condition, perform one or more of the following:

[0218] The first transmission power corresponding to the target SRS is divided equally according to the number of first antenna ports, and the result of the equal division is taken as the transmission power of the antenna port corresponding to the target SRS.

[0219] Divide the first transmission power corresponding to the target SRS by the number of first antenna ports, and use the result of the division as the transmission power of the antenna port corresponding to the target SRS.

[0220] The first transmission power corresponding to the target SRS is evenly distributed across the antenna port corresponding to the target SRS.

[0224] Determine the first transmission power corresponding to the target SRS, and scale the first transmission power so that the ratio of the transmission power of the target SRS to the transmission power of the first SRS is a predefined fixed value, or the ratio of the transmission power of the SRS resource corresponding to the target SRS to the transmission power of the SRS resource corresponding to the first SRS is a predefined fixed value, or the ratio of the transmission power of the antenna port of the target SRS to the transmission power of the antenna port of the first SRS is a predefined fixed value.

[0225] Wherein, the first number of antenna ports is the maximum or minimum number of antenna ports corresponding to each SRS resource in one or more SRS resource sets; the second coefficient is a preset value or a coefficient determined based on the number of antenna ports corresponding to the target SRS and the first number of antenna ports; the third coefficient is a coefficient determined based on the maximum output power that the SRS or SRS resource with the corresponding number of antenna ports equal to the first number of antenna ports can achieve, and the first transmission power corresponding to the SRS or SRS resource with the corresponding number of ports equal to the first number of antenna ports; or the third coefficient is a coefficient determined based on the maximum output power of the terminal and the first transmission power corresponding to the SRS resource with the corresponding number of antenna ports equal to the first number of antenna ports.

[0226] Specifically, in this embodiment of the application, after the network device configures one or more SRS resource sets for the terminal, the terminal can determine the transmission power of the antenna port corresponding to the target SRS based on whether the configuration of each SRS resource in the one or more SRS resource sets meets the first condition.

[0227] Specifically, if the terminal determines that the configuration of each SRS resource in one or more SRS resource sets meets the first condition, the terminal may use one or more of the following methods to determine the transmission power of the antenna port corresponding to the target SRS.

[0228] Method 1: The terminal can divide the first transmission power corresponding to the target SRS equally according to the number of first antenna ports, and then use the result of the equalization as the transmission power of the antenna port corresponding to the target SRS. For example, the first transmission power can be divided by the number of first antenna ports, and the result can be used as the transmission power of each antenna port corresponding to the target SRS.

[0229] Method 2: The terminal can evenly distribute the first transmission power corresponding to the target SRS across the antenna ports corresponding to the target SRS. For example, the first transmission power can be divided by the number of antenna ports corresponding to the target SRS, and the result can be used as the transmission power of each antenna port corresponding to the target SRS.

[0230] Method 3: The terminal can determine the transmission power of the antenna port corresponding to the target SRS based on the first transmission power and the second coefficient. For example, the first transmission power can be scaled using the second coefficient, and the scaled transmission power can be evenly distributed across the antenna port corresponding to the target SRS.

[0231] The second coefficient can be a preset value (any preset value, such as 0.5), or a coefficient determined based on the number of antenna ports corresponding to the target SRS and the number of antenna ports of the first antenna. Optionally, the second coefficient can be determined based on the ratio of the number of antenna ports corresponding to the target SRS to the number of antenna ports of the first antenna. For example, the second coefficient can be the ratio of the number of antenna ports corresponding to the target SRS to the number of antenna ports of the first antenna, or a coefficient related to that ratio.

[0232] Method 4: The terminal can determine the third transmission power corresponding to the target SRS based on the second coefficient, and determine the transmission power of the antenna port corresponding to the target SRS based on the third transmission power.

[0233] Alternatively, the third transmission power can be determined based on the second coefficient and one or more of the following:

[0234] (1) Power control parameters corresponding to the target SRS resource. The power control parameters corresponding to the target SRS resource can be understood as the power control parameters corresponding to the SRS resource set to which the target SRS resource is located. The power control parameters may include one or more of the following: path loss reference signal parameters; target received power parameters; partial path loss compensation parameters; closed-loop power control parameters; and open-loop power control parameters.

[0235] (2) Bandwidth corresponding to the target SRS resource. The bandwidth corresponding to the target SRS resource can be understood as the bandwidth corresponding to the set of SRS resources to which the target SRS resource is located.

[0236] (3) Road loss reference signal corresponding to the target SRS resource. The road loss reference signal corresponding to the target SRS resource can be understood as the road loss reference signal corresponding to the SRS resource set to which the target SRS resource is located.

[0237] (4) Target received power corresponding to the target SRS resource. The target received power corresponding to the target SRS resource can be understood as the target received power corresponding to the set of SRS resources to which the target SRS resource is located.

[0238] (5) Partial road loss compensation factor corresponding to the target SRS resource. The partial road loss compensation factor corresponding to the target SRS resource can be understood as the partial road loss compensation factor corresponding to the SRS resource set to which the target SRS resource is located.

[0239] (6) Closed-loop power control parameters corresponding to the target SRS resource. The closed-loop power control parameters corresponding to the target SRS resource can be understood as the closed-loop power control parameters corresponding to the SRS resource set to which the target SRS resource is located.

[0240] (7) Spatial Relation Info corresponding to the target SRS resource. The spatial relation Info corresponding to the target SRS resource can be understood as the spatial relation Info corresponding to the SRS resource set to which the target SRS resource is located. For example, it can be the transmission spatial relation Info indicated by the Transmission Configuration Indication (TCI) state corresponding to the target SRS resource or SRS resource set; for example, it can be the Quasi-Co-Location (QCL) parameter corresponding to the target SRS resource or SRS resource set.

[0241] (8) The maximum output power of the terminal.

[0242] For example, the third transmission power can be the transmission power P'' corresponding to the SRS, calculated using the second coefficient and power control parameters according to the following formula. SRS,b,f,c (i,q s (For an explanation of the parameters in this formula, please refer to Section 7.3.1 of 3GPP Protocol TS38.213 V16.7.0 (2021-09), where k2 represents the second coefficient):

[0243]

[0244] The transmission power of the antenna port corresponding to the target SRS can be determined by the third transmission power, which can be achieved by evenly distributing the third transmission power across the antenna port corresponding to the target SRS.

[0245] Method 5: The terminal can determine the transmission power of the antenna port corresponding to the target SRS based on the first transmission power and the third coefficient corresponding to the target SRS.

[0246] The third coefficient can be a coefficient determined based on the maximum output power that the SRS or SRS resource with the number of corresponding antenna ports equal to the number of first antenna ports, and the first transmission power corresponding to the SRS or SRS resource with the number of corresponding antenna ports equal to the number of first antenna ports; or the third coefficient can be a coefficient determined based on the maximum output power of the terminal and the first transmission power corresponding to the SRS resource with the number of corresponding antenna ports equal to the number of first antenna ports.

[0247] Optionally, the third coefficient may be determined based on the ratio of the maximum output power achievable by the SRS or SRS resource with the corresponding number of antenna ports equal to the first number of antenna ports to the first transmission power of the SRS or SRS resource with the corresponding number of ports equal to the first number of antenna ports. For example, the third coefficient may be the ratio of the maximum output power achievable by the SRS or SRS resource with the corresponding number of antenna ports equal to the first number of antenna ports to the first transmission power of the SRS or SRS resource with the corresponding number of ports equal to the first number of antenna ports, or a coefficient related to this ratio.

[0248] Optionally, the third coefficient may be determined based on the ratio of the terminal's maximum output power to the first transmission power corresponding to the SRS resource with the number of antenna ports equal to ...

[0249] Optionally, the terminal's maximum output power can be the maximum output power that the terminal can achieve; or, it can be the maximum output power calculated by the terminal based on the terminal's power level and / or parameters indicated by the network device. For example, the terminal's maximum output power can refer to P... CMAX,f,c (i).

[0250] Optionally, the terminal determines the transmission power of the antenna port corresponding to the target SRS based on the first transmission power and the third coefficient. This can be achieved by scaling the first transmission power using the third coefficient and then distributing the scaled transmission power equally across the antenna port corresponding to the target SRS.

[0251] For example, in a 4T6R system, the base station configures a terminal with one 4-port SRS resource and one 2-port SRS resource. When the terminal transmits using the 2-port SRS resource, its maximum supported output power is Pm. If the terminal's calculated first transmission power P1 for the 2-port SRS resource is greater than Pm, the terminal cannot actually transmit the 2-port SRS at P1; it can only transmit at Pm. In this case, the transmission power of the 4-port SRS can be adjusted by scaling it using a third coefficient s. For example, the transmission power of the 4-port SRS can be multiplied by s, where s = Pm / P1. This ensures that the transmission power of the 2-port and 4-port SRS remains constant.

[0252] For example, in 4T6R, the base station configures a 4-port SRS resource and a 2-port SRS resource for the terminal. The terminal can always use the third coefficient s = Pm / P1 for scaling of the 4-port SRS resource, without needing to determine whether the transmission power of the 2-port SRS resource is greater than Pm, where P1 is the first transmission power of the 2-port SRS resource.

[0253] Method Six: The terminal can first determine the first transmission power corresponding to the target SRS, and then scale the first transmission power so that the ratio of the transmission power of the target SRS to the transmission power of the first SRS is a predefined fixed value, or the ratio of the transmission power of the SRS resource corresponding to the target SRS to the transmission power of the SRS resource corresponding to the first SRS is a predefined fixed value, or the ratio of the transmission power of the antenna port of the target SRS to the transmission power of the antenna port of the first SRS is a predefined fixed value.

[0254] Here, the target SRS is the SRS with the first number of antenna ports, and the first SRS is the SRS with the second number of antenna ports. That is to say, the target SRS and the first SRS can be two SRS with different numbers of antenna ports. For example, the target SRS can be an SRS with 4 antenna ports, and the first SRS can be an SRS with 2 antenna ports.

[0255] The transmission power of the target SRS is determined by scaling the first transmission power corresponding to a certain proportion and then evenly distributing the scaled transmission power across the antenna ports corresponding to the target SRS. It should be noted that the scaling ratio is not specifically limited, as long as the ratio of the transmission power of the target SRS to the transmission power of the first SRS is a predefined fixed value, or the ratio of the transmission power of the SRS resource corresponding to the target SRS to the transmission power of the SRS resource corresponding to the first SRS is a predefined fixed value, or the ratio of the transmission power of the antenna port of the target SRS to the transmission power of the first SRS is a predefined fixed value.

[0256] Optionally, the first condition may include one or more of the following conditions:

[0257] (1) Each SRS resource in one or more SRS resource sets is an SRS resource in the SRS resource set corresponding to the first switching mode.

[0258] For example, if the first switching mode is the 4T6R antenna switching mode, and one or more SRS resource sets are SRS resource sets corresponding to the 4T6R antenna switching mode, the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to one or more of the above methods one to six.

[0259] (2) At least two SRS resources in one or more SRS resource sets have different numbers of antenna ports.

[0260] For example, if there is a 4-port SRS resource and a 2-port SRS resource in one or more SRS resource sets, the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to one or more of the methods one to six above.

[0261] (3) Each SRS resource in one or more SRS resource sets includes at least one SRS resource with the number of antenna ports equal to a first specified value and at least one SRS resource with the number of antenna ports equal to a second specified value.

[0262] For example, if the first specified value is 4 and the second specified value is 2, then if there is a 4-port SRS resource and a 2-port SRS resource in one or more SRS resource sets, the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to one or more of the methods one to six above.

[0263] (4) The number of antenna ports corresponding to each SRS resource in one or more SRS resource sets is equal to the third specified value.

[0264] For example, if the third specified value is 2, then if the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets is equal to 2, that is, each SRS resource is a 2-port SRS resource, then the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to one or more of the above methods one to six.

[0265] (5) Each SRS resource in one or more SRS resource sets includes at least one SRS resource with 4 antenna ports and at least one SRS resource with 2 antenna ports.

[0266] For example, if there is a 4-port SRS resource and a 2-port SRS resource in one or more SRS resource sets, the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to one or more of the methods one to six above.

[0267] (6) The number of antenna ports corresponding to each SRS resource in one or more SRS resource sets is equal to 2;

[0268] For example, if the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets is equal to 2, that is, each SRS resource is a 2-port SRS resource, then the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to one or more of the methods one to six above.

[0269] (7) The number of antenna ports corresponding to each SRS resource in one or more SRS resource sets is less than the maximum number of SRS antenna ports supported by the terminal.

[0270] For example, if the maximum number of SRS antenna ports supported by the terminal is 4, then if the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets is less than 4, such as each SRS resource being a 2-port SRS resource, then the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to one or more of the methods one to six above.

[0271] (8) The first transmission power of each SRS corresponding to each SRS resource in one or more SRS resource sets is greater than the maximum output power supported by each SRS resource.

[0272] For example, if there is an SRS resource in one or more SRS resource sets whose first transmission power is greater than the maximum output power supported by the SRS resource, the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to one or more of the methods one to six above.

[0273] (9) The first transmission power of the SRS corresponding to the SRS resource with the specified number of antenna ports in one or more SRS resource sets is greater than the maximum output power supported by the SRS resource with the specified number of antenna ports.

[0274] For example, if the specified number of antenna ports is 2, then if there is a 2-port SRS resource in one or more SRS resource sets, and the first transmission power of the SRS corresponding to the 2-port SRS resource is greater than the maximum output power supported by the 2-port SRS resource, then the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to one or more of the methods one to six above.

[0275] The SRS transmission power determination method provided in this application embodiment allows the terminal to determine the transmission power of the antenna port corresponding to the target SRS only for the target SRS corresponding to the target SRS in the SRS resource set that meets the first condition, using one or more of the methods one to six described above. For other SRS corresponding to SRS in the SRS resource set that do not meet the first condition, the existing SRS power control mechanism can still be used to determine the transmission power of the antenna port corresponding to the SRS, thereby improving the flexibility of SRS power control.

[0276] Optionally, the method further includes:

[0277] Determine the first transmission power corresponding to the target SRS, and scale the first transmission power so that the ratio of the transmission power of the target SRS to the transmission power of the first SRS is a predefined fixed value, or the ratio of the transmission power of the SRS resource corresponding to the target SRS to the transmission power of the SRS resource corresponding to the first SRS is a predefined fixed value, or the ratio of the transmission power of the antenna port corresponding to the target SRS to the transmission power of the antenna port corresponding to the first SRS is a predefined fixed value.

[0278] Wherein, the target SRS is the SRS with the specified first number of antenna ports, and the first SRS is the SRS with the specified second number of antenna ports.

[0279] Specifically, the terminal can first determine the first transmission power corresponding to the target SRS, and then scale the first transmission power so that the ratio of the transmission power of the target SRS to the transmission power of the first SRS is a predefined fixed value, or the ratio of the transmission power of the SRS resource corresponding to the target SRS to the transmission power of the SRS resource corresponding to the first SRS is a predefined fixed value, or the ratio of the transmission power of the antenna port of the target SRS to the transmission power of the antenna port of the first SRS is a predefined fixed value.

[0280] Here, the target SRS is the SRS with the first number of antenna ports, and the first SRS is the SRS with the second number of antenna ports. That is to say, the target SRS and the first SRS can be two SRS with different numbers of antenna ports. For example, the target SRS can be an SRS with 4 antenna ports, and the first SRS can be an SRS with 2 antenna ports.

[0281] The transmission power of the target SRS is determined by scaling the first transmission power corresponding to a certain proportion and then evenly distributing the scaled transmission power across the antenna ports corresponding to the target SRS. It should be noted that the scaling ratio is not specifically limited, as long as the ratio of the transmission power of the target SRS to the transmission power of the first SRS is a predefined fixed value, or the ratio of the transmission power of the SRS resource corresponding to the target SRS to the transmission power of the SRS resource corresponding to the first SRS is a predefined fixed value, or the ratio of the transmission power of the antenna port of the target SRS to the transmission power of the first SRS is a predefined fixed value.

[0282] Optionally, the method further includes:

[0283] Receive the first signaling sent by the network device. The first signaling is used to indicate the method for determining the SRS transmission power.

[0284] Specifically, in this embodiment, the network device can send a first signaling message to the terminal. This first signaling message is used to indicate the method for determining the SRS transmission power. That is, the terminal can determine, according to the instruction of the network device, which method to use to determine the transmission power of the antenna port corresponding to the SRS. For example, the network device can instruct the terminal to determine the transmission power of the antenna port corresponding to the target SRS based on the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets configured by the network device.

[0285] The aforementioned first signaling can be Radio Resource Control (RRC) signaling, or any other signaling that can be used by network devices to send instruction information to terminals, without any specific restrictions.

[0286] The SRS transmission power determination method provided in this application embodiment allows the terminal to determine the transmission power of the antenna port corresponding to the SRS in different ways according to different instructions sent by the network device, thereby improving the flexibility of SRS power control.

[0287] Figure 2 This is a second flowchart illustrating the SRS transmission power determination method provided in this application embodiment. This method can be applied to network devices (e.g., base stations), such as... Figure 2 As shown, the method includes the following steps:

[0288] Step 200: The method for determining the transmission power of the antenna port corresponding to the target SRS is to determine the transmission power of the antenna port corresponding to the target SRS based on the configuration of each SRS resource in one or more SRS resource sets; the target SRS is the SRS corresponding to the target SRS resource in one or more SRS resource sets.

[0289] Step 201: Based on the configuration of each SRS resource in one or more SRS resource sets, determine the relative relationship between the transmission power of the antenna port corresponding to the target SRS and the transmission power of the antenna ports corresponding to other SRSs.

[0290] Specifically, network devices can configure one or more SRS resource sets for terminals, and each SRS resource set includes one or more SRS resources.

[0291] In this embodiment of the application, after the terminal determines the transmission power of the antenna port corresponding to the target SRS based on the configuration of each SRS resource in one or more SRS resource sets, it can send the target SRS to the network device according to the determined transmission power of the antenna port corresponding to the target SRS.

[0292] After receiving a target SRS, the network device determines the transmission power of the antenna port corresponding to the target SRS by determining the transmission power of the antenna port corresponding to the target SRS based on the configuration of each SRS resource in one or more SRS resource sets. Then, based on the configuration of each SRS resource in one or more SRS resource sets, the relative relationship between the transmission power of the antenna port corresponding to the target SRS and the transmission power of the antenna ports corresponding to other SRSs can be determined. Optionally, this relative relationship can be the ratio between the transmission power of the antenna port corresponding to the target SRS and the transmission power of the antenna ports corresponding to other SRSs. Other SRSs refer to the SRSs corresponding to other SRS resources in the one or more SRS resource sets besides the target SRS resource.

[0293] For example, the SRS resource set configured by the network device for the terminal includes 2-port SRS resources and 4-port SRS resources. After the terminal sends SRS to the network device, the network device can determine the ratio between the transmission power of the antenna port corresponding to the 2-port SRS and the transmission power of the antenna port corresponding to the 4-port SRS when determining DL CSI, based on the configuration of each SRS resource in the SRS resource set. This allows the network device to obtain the relative channel quality between downlink receiving antennas and guide downlink scheduling.

[0294] Optionally, the relative relationship between the transmission power of the antenna port corresponding to the target SRS and the transmission power of the antenna ports corresponding to other SRSs can be a ratio determined based on the number of antenna ports corresponding to each SRS resource in the one or more SRS resource sets, or it can be a predefined fixed value.

[0295] For example, network devices can determine downlink channel / downlink signal scheduling information based on a predefined fixed value of the ratio of the transmission power of the target SRS to the transmission power of the first SRS; or, based on a predefined fixed value of the ratio of the transmission power of the SRS resource corresponding to the target SRS to the transmission power of the SRS resource corresponding to the first SRS; or, based on a predefined fixed value of the ratio of the transmission power of the antenna port of the target SRS to the transmission power of the antenna port of the first SRS. Optionally, the downlink channel is a Physical Downlink Shared Channel (PDSCH).

[0296] The SRS transmission power determination method provided in this application embodiment allows a network device to determine the relative relationship between the transmission power of the antenna port corresponding to the target SRS and the transmission power of the antenna ports corresponding to other SRSs based on the configuration of each SRS resource in one or more SRS resource sets. Thus, regardless of the RF chain structure of the terminal, the network device's understanding of the SRS transmission power can be consistent with the actual transmission power of the SRS sent by the terminal.

[0297] Optionally, based on the configuration of each SRS resource in one or more SRS resource sets, the relative relationship between the transmission power of the antenna port corresponding to the target SRS and the transmission power of the antenna ports corresponding to other SRSs is determined, including:

[0298] Based on the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets, determine the relative relationship between the transmission power of the antenna port corresponding to the target SRS and the transmission power of the antenna ports corresponding to other SRSs.

[0299] Specifically, in this embodiment, the network device can determine the relative relationship between the transmission power of the antenna port corresponding to the target SRS and the transmission power of the antenna ports corresponding to other SRSs based on the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets. For example, the ratio between the transmission powers of the antenna ports corresponding to each SRS can be determined based on the ratio (direct or inverse) of the number of antenna ports corresponding to each SRS resource. For instance, when determining DLCSI, the network device can determine that the transmission power of the antenna port corresponding to a 2-port SRS is 1 / 2 or 2 times the transmission power of the antenna port corresponding to a 4-port SRS based on the number of antenna ports, thereby obtaining the relative channel quality between downlink receiving antennas and guiding downlink scheduling.

[0300] Optionally, the method further includes:

[0301] Send a first signaling message to the terminal. The first signaling message is used to indicate the method for determining the SRS transmission power.

[0302] Specifically, in this embodiment, the network device can send a first signaling message to the terminal. This first signaling message is used to indicate the method for determining the SRS transmission power, so that the terminal can determine, according to the instruction of the network device, which method to use to determine the transmission power of the antenna port corresponding to the SRS. For example, the network device can instruct the terminal to determine the transmission power of the antenna port corresponding to the target SRS based on the number of antenna ports corresponding to each SRS resource in one or more SRS resource sets configured by the network device.

[0303] The aforementioned first signaling can be RRC signaling, or any other signaling that can be used by network devices to send instruction information to terminals, without any specific restrictions.

[0304] The SRS transmission power determination method provided in this application embodiment allows the terminal to determine the transmission power of the antenna port corresponding to the SRS in different ways according to different instructions sent by the network device, thereby improving the flexibility of SRS power control.

[0305] The above SRS transmission power determination method will be illustrated below with specific examples.

[0306] Example 1: Determine the SRS transmission power based on the maximum number of antenna ports configured across multiple SRS resources. The specific steps are as follows:

[0307] Step 1-1: Obtain the configuration parameters of multiple SRS resources sent by the network device;

[0308] Step 1-2: Determine the SRS transmission power based on the maximum number of antenna ports configured for multiple SRS resources.

[0309] For the core step (step 2):

[0310] Consider K SRS resources, where the number of antenna ports for these K SRS resources are p1, p2, ..., p1, p2, ..., p3, p4, p5, p6, p7, p8, p9, p1, p1, p1, p2, p1, p2, p1, p2, p1, p2, p3, p1 ...2, p1, p2, p3, p1, p1 K Then, according to max(p1,p2,…,p K Determine the transmission power of the SRS ports corresponding to these SRS resources.

[0311] Optionally, for any one of the SRS resources, the transmission power calculated based on the power control parameters will be set according to max(p1,p2,…,p...). K The power of each SRS antenna port corresponding to this SRS resource is obtained by dividing the ports equally.

[0312] Example 1: For the SRS antenna switching pattern 4T6R, the base station configures one 4-port SRS resource and one 2-port SRS resource for the terminal. For any given SRS resource, the transmission power corresponding to that SRS resource is calculated based on the power control parameters, and then evenly divided among the 4 ports to obtain the transmission power for each SRS antenna port corresponding to that SRS resource.

[0313] Optionally, the transmission power of other SRS resources can be determined based on the transmission power of the SRS resource with the largest number of configured antenna ports among multiple SRS resources.

[0314] Example 2: Taking a base station as the terminal, an SRS resource set with usage "antennaSwitching" is configured. This SRS resource set includes a 4-port SRS resource and a 2-port SRS resource. The transmission power of each antenna port of the SRS resource with the largest number of antenna ports (the 4-port SRS resource) calculated according to the power control parameters is used as the transmission power of each SRS antenna port of the other SRS resource (the 2-port SRS resource).

[0315] Example 2: Determine the SRS transmission power based on the relative number of antenna ports configured for multiple SRS resources. The specific steps are as follows:

[0316] Step 2-1: Obtain the configuration parameters of multiple SRS resources sent by the network device;

[0317] Step 2-2: Determine the transmission power of SRS based on the relative relationship of the number of antenna ports configured for multiple SRS resources.

[0318] Optionally, the relative relationship is the ratio of the number of antenna ports. For example, for any SRS resource, it is the ratio m / n of the number of antenna ports configured for that SRS resource and the maximum number of antenna ports configured for multiple SRS resources, where m is the number of SRS ports configured for that SRS resource and n is the maximum number of antenna ports configured for multiple SRS resources.

[0319] Optionally, for a given SRS resource, the specific method for determining the SRS transmission power based on the relative number of antenna ports configured in multiple SRS resources is as follows: determine the transmission power of the SRS resource according to the power control parameters, and then scale the transmission power using m / n, distributing the scaled power evenly to each SRS port corresponding to the SRS resource. Optionally, scaling using m / n is not used for the SRS resource with the most SRS antenna ports.

[0320] Example 3: Consider multiple SRS resources configured with the same time-domain type for DL ​​CSI acquisition. For instance, multiple SRS resources have their higher-layer signaling resourceType configured as "aperiodic" and their higher-layer signaling usage configured as "antennaSwitching". Assume these multiple SRS resources are one 4-port SRS resource and one 2-port SRS resource. For the 4-port SRS resource, the transmission power corresponding to the SRS resource is calculated based on the power control parameters, evenly distributed across the 4 ports, and used as the transmission power for each configured antenna port. For the 2-port SRS resource, the transmission power corresponding to the SRS resource is calculated based on the power control parameters, scaled by 2 / 4 (i.e., 1 / 2), and then evenly distributed across its two SRS antenna ports. Optionally, the transmission power corresponding to the SRS can be calculated based on the power control parameters using the following method (for an explanation of each parameter in this formula, please refer to section 7.3.1 of 3GPP protocol TS38.213V16.7.0 (2021-09)):

[0321]

[0322] Optionally, for a given SRS resource, the specific method for determining the SRS transmission power based on the relative number of antenna ports configured in multiple SRS resources is as follows: The transmission power of the SRS resource, determined based on power control parameters and scaling factors, is then evenly distributed across the corresponding SRS antenna ports. The formula for calculating the transmission power of the SRS resource using power control parameters and scaling factors includes a scaling factor of m / n. Optionally, scaling using m / n is not applied to the SRS resource with the most SRS antenna ports.

[0323] Example 4: The transmission power of the SRS resource is calculated using the following formula with power control parameters and scaling factor (where m is the number of SRS ports configured for the SRS resource, n is the maximum number of antenna ports configured for multiple SRS resources, and the explanation of other parameters can be found in Section 7.3.1 of 3GPP protocol TS38.213 V16.7.0 (2021-09):

[0324]

[0325] The terminal will distribute the transmission power of the SRS resource calculated according to the above formula equally across all antenna ports configured for the SRS resource.
