This application claims the priority of the Chinese patent application with the application number 2021113088665 filed on November 05, 2021, and the title of the invention is "SRS transmission power determination method, device, device and storage medium", which is incorporated herein by reference in its entirety .

technical field

The present disclosure relates to the technical field of wireless communication, and in particular to a method, device, device and storage medium for determining SRS transmission power.

Background technique

In the 3rd Generation Partnership Project (3GPP) New Radio (NR) system, in order to better obtain downlink channel state information (Downlink Channel State Information, DL CSI), the terminal can Report its supported Sounding Reference Signal (SRS) antenna switching capability (in the NR system protocol, it can be reported through the terminal capability signaling srs-TxSwitch, etc.), and the antenna switching capability reported by the terminal is used to indicate the terminal supported xTyR capability (where xTyR can be one or more of 1T1R, 1T2R, 1T4R, 2T2R, 2T4R, 1T6R, 1T8R, 2T6R, 2T8R, 4T6R, and 4T8R, and with the further improvement of the protocol, its candidate values are also may continue to increase).

A network device (such as a base station) may configure one or more SRS resource sets for acquiring DL CSI for the terminal according to the antenna switching capability reported by the terminal, and 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, and the terminal uses the power control parameters corresponding to the SRS resource set where the SRS resource is located to determine the transmission power corresponding to the SRS resource, and then set the The transmission power is equally divided on all antenna ports where SRS resources are configured. In the NR system Rel-16 protocol, the following formula is used to calculate the transmission power corresponding to the SRS resource, that is, the transmission capability of the SRS cannot be greater than the maximum transmission power P _CMAX,f,c (i) (for the explanation of each parameter, please refer to the 3GPP protocol TS38. Section 7.3.1 of 213V16.7.0 (2021-09):

Correspondingly, when determining the DL CSI quality, the base station compares the relative channel quality between the downlink receiving antennas according to the same transmission power corresponding to each SRS resource, so as to guide the downlink scheduling.

However, for terminals capable of switching antennas such as 4T6R or 4T8R, the existing SRS power control mechanism may not work well due to the structure of its transmit channel (RF chain). For example, for a terminal supporting 4T6R, if its four RF chains are all 17dBm power amplifiers (Power Amplifier, PA), the maximum output power corresponding to the power level of the terminal is 23dBm, if the base station configures a usage for the terminal An SRS resource set for antennaSwitching, including a 4-port SRS resource and a 2-port SRS resource, according to the existing SRS power control mechanism, when the SRS transmission power calculated according to the power control parameters does not reach the maximum transmission power, the total transmission power of the two SRS resources is the same; when the transmission power of the SRS calculated according to the power control parameters reaches the maximum transmission power P _CMAX,f,c (i)=23dBm, for the SRS resources of 4 ports, each The transmit power of each port should be a quarter of 23dBm, that is, 17dBm. For a 2-port SRS resource, the transmit power of each port should be one-half of 23dBm, that is, 20dBm. Since the terminal’s PA cannot reach 20dBm, The terminal can only use 17dBm to send each antenna port of the 2-port SRS resource. However, the base station always determines the DL CSI quality according to the total transmission power of 2-port SRS resources and the total transmission power of 4-port SRS resources, which will cause the SRS transmission power calculated by the terminal according to the power control parameters to be near the maximum transmission power The base station wrongly predicts the quality of DL CSI, so that optimal downlink scheduling cannot be performed.

Detailed ways

The term "and/or" in the embodiments of the present disclosure describes the association relationship of associated objects, indicating that there may be three relationships, for example, A and/or B, which may mean: A exists alone, A and B exist simultaneously, and B exists alone These three situations. The character "/" generally indicates that the contextual objects are an "or" relationship.

The term "plurality" in the embodiments of the present disclosure refers to two or more, and other quantifiers are similar.

The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

FIG. 1 is one of the schematic flowcharts of the method for determining SRS transmission power provided by an embodiment of the present disclosure. The method can be applied to a terminal. As shown in FIG. 1 , the method includes the following steps:

Step 100: Determine the transmission power of the antenna port corresponding to the target SRS according to the configuration of at least one SRS resource in the one or more SRS resource sets, where the target SRS is the SRS corresponding to the target SRS resource in the one or more SRS resource sets.

Optionally, the configuration of at least one SRS resource in the one or more SRS resource sets includes the configuration of all or part of the SRS resources in the one or more SRS resource sets.

Optionally, the configuration of all SRS resources in one or more SRS resource sets is the configuration of each SRS resource in the one or more SRS resource sets.

Specifically, a network device (such as a base station) may configure one or more SRS resource sets for the terminal, and each SRS resource set includes one or more SRS resources.

In the existing SRS power control mechanism, the terminal always determines the transmission power of the antenna port where each SRS resource is configured according to the respective configuration of each SRS resource, which may cause network equipment to fail in certain RF chain structures The understanding of the relative relationship between the transmission power of different SRSs is inconsistent with the actual transmission power of the SRS sent by the terminal, thus making a wrong judgment. For example, when the SRS resources are used for DL CSI acquisition, the network device will make a wrong judgment on the quality of the DL CSI. Therefore, optimal downlink scheduling cannot be performed.

In order to avoid the above problems, in the embodiments of the present disclosure, the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to the configuration of at least one SRS resource in one or more SRS resource sets, and the target SRS is corresponding to one or more For the SRS of the target SRS resource in the SRS resource set, the transmission power of the antenna port corresponding to the target SRS can be understood as the transmission power corresponding to the antenna port where the target SRS resource is configured.

For example, the network device configures an SRS resource set for the terminal, and the terminal determines the transmission power of the antenna port corresponding to the target SRS according to the configuration of at least one SRS resource in the SRS resource set; Multiple SRS resource sets, the terminal determines the transmission power of the antenna port corresponding to the target SRS according to the configuration of at least one SRS resource in the multiple SRS resource sets.

Therefore, regardless of the structure of the terminal's RF chain, 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 terminal's actual SRS transmission power.

It should be understood that the technical solutions of the embodiments of the present disclosure are not only applicable to SRS resources for DL CSI acquisition, but also applicable to SRS resources for other purposes, which are not specifically limited here. For example, the SRS resource may be an SRS resource of a certain purpose type used in a coordinated multi-point (Multi-Transmit Receive Point, M-TRP) scenario, or an SRS resource used for uplink CSI acquisition (for example, the high-layer parameter usage is configured as The SRS resource in the SRS resource set of "codebook", or the high-level parameter usage is configured as the SRS resource in the SRS resource set of "nonCodebook", or the SRS resource used for interference measurement, or the SRS resource used for beam management ,etc. For the convenience of subsequent discussion, each embodiment of the present disclosure is introduced by taking the SRS resource used for DL CSI acquisition as an example.

Optionally, at least one SRS resource in one or more sets of SRS resources may be an SRS resource used for the same purpose. For example, at least one SRS resource in one or more SRS resource sets may be an SRS resource used for DL CSI acquisition, such as an SRS resource whose high-layer signaling usage is configured as "antennaSwitching".

Optionally, at least one SRS resource in the one or more SRS resource sets may be an SRS resource used for the same purpose and configured as the same time domain type. For example, at least one SRS resource in one or more SRS resource sets may be an SRS resource configured as the same time domain type among the SRS resources used for DL CSI acquisition. Some examples of time domain types include: periodic, aperiodic, semi-persistent. For example, the high-layer signaling resourceType is configured as "aperiodic", and the high-layer signaling usage is configured as an SRS resource of "antennaSwitching". For another example, the high-layer signaling resourceType is configured as "periodic", and the high-layer signaling usage is configured as an SRS resource of "antennaSwitching". For another example, the high-layer signaling resourceType is configured as "semi-persistent", and the high-layer signaling usage is configured as an SRS resource of "antennaSwitching".

Optionally, at least one SRS resource in one or more SRS resource sets may be a specific type of SRS resource. For example, at least one SRS resource in one or more SRS resource sets is used for a specific SRS transmission port switching pattern (in some embodiments, it can be expressed as "SRS antenna switching pattern", "DL CSI acquired Antenna Switching Pattern", "SRS Antenna Switching Mode", "DL CSI Obtaining Antenna Switching Mode", etc.) SRS resources. resource.

Optionally, at least one SRS resource in the one or more SRS resource sets includes all or part of the SRS resources in the one or more SRS resource sets.

Optionally, all the SRS resources in the one or more SRS resource sets, that is, each SRS resource in the one or more SRS resource sets.

Step 101. Send the target SRS according to the transmission power.

Specifically, after the terminal determines the transmission power of the antenna port corresponding to the target SRS according to the configuration of at least one SRS resource in one or more SRS resource sets, it can transmit to the network according to the determined transmission power of the antenna port corresponding to the target SRS. The device sends the target SRS.

In the SRS transmission power determination method provided by the embodiments of the present disclosure, the terminal can determine the transmission power of the antenna port corresponding to the target SRS according to the configuration of at least one SRS resource in one or more SRS resource sets, so that no matter what structure the RF chain of the terminal is , 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 transmission power of the terminal actually sending the 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 each transmission power corresponding to the target SRS The transmit power of the antenna port.

Optionally, the second The coefficient may be determined according to the ratio of the number of antenna ports corresponding to the target SRS to the number of first antenna ports, for example, the second coefficient may be the ratio of the number of antenna ports corresponding to the target SRS to the number of first antenna ports, or may be related to the ratio coefficient.

For example, the third coefficient may be the terminal's A ratio of the maximum output power to the first transmission power corresponding to the SRS resource corresponding to the first number of antenna ports, or a coefficient related to the ratio.

Optionally, the maximum output power of the terminal may be the maximum output power that the terminal can achieve; or, it may be the maximum output power calculated by the terminal according to the power level of the terminal and/or parameters indicated by the network device.

When the terminal transmits on 2-port SRS resources, the maximum output power it supports is Pm, and when the first transmission power P1 calculated by the terminal for 2-port SRS resources is greater than Pm, the terminal cannot actually transmit 2-port SRS with P1 , can only transmit 2-port SRS in Pm. Then, in this case, the transmission power of the 4-port SRS can be adjusted, and the transmission power of the 4-port SRS can be scaled by the third coefficient s, for example, the transmission power of the 4-port SRS is multiplied by s, s=Pm/P1 . In this way, the transmission power of the 2-port SRS and the 4-port SRS is always constant.

Wherein, the target SRS is an SRS whose number of antenna ports is a first value, and the first SRS is an SRS whose number of antenna ports is a second value. That is to say, the target SRS and the first SRS may be two SRSs corresponding to different numbers of antenna ports. For example, the target SRS may be an SRS with 4 antenna ports, and the first SRS may be an SRS with 2 antenna ports.

The transmission power of the antenna port corresponding to the target SRS is determined by scaling the first transmission power corresponding to the target SRS by a certain ratio, and then equally dividing the scaled transmission power on the antenna ports corresponding to the target SRS. It should be noted that the scaling ratio is not specifically limited here, 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 transmission of the SRS resource corresponding to the target SRS The ratio of the power 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.
