Description

Method, device and storage medium for determining transmission power of detection reference signal

The present invention belongs to the field of communication technology, and particularly relates to a method, device and storage medium for determining the transmission power of a sounding reference signal (SRS).

In the current system, the network equipment can configure the relative power control parameters for each SRS resource set. The terminal/user equipment (UE) 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 divides the transmission power equally among all antenna ports where the SRS resource is configured.

Since the network equipment does not know when the transmit power of the SRS resource reaches the maximum output power, the network equipment always determines the downlink (DL) channel state information (CSI) quality according to the total transmit power of the 2-port SRS resources being the same as the total transmit power of the 4-port SRS resources. This will cause the network equipment to make an incorrect prediction of the DL CSI quality when the SRS transmit power calculated by the UE based on the power control parameters is near the maximum output power, making it impossible to perform the optimal downlink scheduling.

The SRS transmission power determination method, device and storage medium provided by the present invention determine the transmission power of the target SRS by using the transmission capability and/or configuration information, thereby increasing the flexibility of system scheduling so that the network equipment can correctly judge the DL CSI or UL CSL quality, thereby achieving the optimal downlink scheduling or uplink scheduling.

In current systems, such as the New Radio (NR) system of the 3rd Generation Partnership Project (3GPP), in order to better obtain DL CSI, the terminal can report its supported transmission capabilities to the network equipment.

The network equipment configures one or more SRS resource sets for obtaining DL CSI for the UE according to the transmission capability reported by the UE. Each SRS resource set includes one or more SRS resources. The network equipment configures the corresponding power control parameters for each SRS resource set. The UE 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. The transmission power is evenly distributed on all antenna ports where the SRS resources are configured.

The transmission power corresponding to the SRS resource determined by the UE cannot exceed the maximum output power limit of the UE. If the transmission power determined by the UE using the power control parameter corresponding to the SRS resource set where the SRS resource is located is greater than the maximum output power, the UE sets the transmission power to the maximum output power and then divides it equally among all antenna ports where the SRS resource is configured.

In the existing system, the number of SRS antenna ports corresponding to the SRS resources used to obtain DL CSI is the same. By configuring all SRS resources in the same SRS resource set, or configuring multiple SRS resource sets used for DL CSI acquisition with the same power control parameters, the relative transmission power of the antenna ports of each SRS resource can be made the same, so that the network equipment can obtain the relative channel quality between the downlink receiving antennas and better perform downlink scheduling.

For UEs with 4T6R and other transmission capabilities, the existing SRS power control mechanism may not work well. The maximum output power of the UE uplink signal is related to the UE's radio frequency chain (RF chain) structure. For example, if the UE's transmission capability is 4T6R, there may be multiple RF chain structures.

For example, there are 2 RF chains that can each switch between 2 Rx antennas, and each of the 2 RF chains is only connected to one Rx antenna; for another example, 4 RF chains can each switch between 2 Rx antennas, etc. The power amplifier (PA) capabilities of the UE may also be different, for example, the maximum transmit power of all 4 PAs may be 23dBm, or the maximum transmit power of all 4 PAs may be 17dBm, or the maximum transmit power of 2 PAs may be 20dBm, and the maximum transmit power of 2 PAs may be 17dBm, etc.

If the existing SRS power control mechanism is still used, in some scenarios, the UE's transmit power at the SRS port will be inconsistent with the network equipment's expectations, causing the network equipment to make incorrect predictions about the DL CSI quality, affecting downlink performance.

For example, for a UE supporting 4T6R, if its four RF chains are all 17dBm PAs, the maximum output power corresponding to the UE's power level is 23dBm. If the network equipment configures an SRS resource set for the UE with the usage of antenna switching, 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 output power, the total transmission power of the two SRS resources is the same; when the SRS transmission power calculated according to the power control parameters reaches the maximum output power P_(CMAX, f, c) (i) equal to 23dBm, for the 4-port SRS resources, the transmission power of each port should be one-fourth of 23dBm, that is, 17dBm, and for the 2-port SRS resources, the transmission power of each port should be one-half of 23dBm, that is, 20dBm. Since the UE's PA cannot reach 20dBm, the UE can only use 17dBm to transmit each antenna port of the 2-port SRS resources.

Since the network equipment does not know when the transmit power of the SRS resources reaches the maximum output power, the network equipment always determines the DL CSI quality according to the total transmit power of the 2-port SRS resources being the same as the total transmit power of the 4-port SRS resources. This will cause the network equipment to make an incorrect prediction of the DL CSI quality when the SRS transmit power calculated by the UE based on the power control parameters is near the maximum output power, making it impossible to perform the optimal downlink scheduling.

In view of the above technical problems, the embodiment of the present invention determines the transmission power of SRS by using the transmission capability and/or configuration information to solve the technical problem that the optimal downlink scheduling cannot be performed in the prior art.

For example, the transmission capability includes the power capability of SRS transmission supported by the terminal, the maximum number of transmit antennas supported by the terminal, and the SRS transmission port switching pattern supported by the terminal.

For example, the transmission capability includes the power capability of SRS transmission supported by the terminal, the maximum number of transmit antennas supported by the terminal, the full power transmission mode supported by the terminal, and the SRS transmission port switching pattern supported by the terminal.

In some embodiments, the power capability of SRS transmission supported by the terminal includes one or more of the following: whether the SRS corresponding to the SRS resources with a specified number of antenna ports can achieve the maximum output power capability; whether the SRS corresponding to all SRS resources corresponding to the specified SRS transmission port switching pattern can achieve the maximum output power capability; whether the SRS corresponding to the SRS resources with a number of antenna ports less than the maximum number of transmitting antennas supported by the terminal can achieve the maximum output power capability.

For example, the maximum output power of the terminal is 23dBm, the number of antenna ports is specified as 2 ports, and the transmission power of the target SRS corresponding to the SRS resources of port 2 is 25dBm. Then the transmission power of the target SRS corresponding to the SRS resources of port 2 can reach the maximum output power of the terminal, that is, the power capability of SRS transmission supported by the terminal has the ability that the transmission power of the target SRS corresponding to the SRS resources of port 2 can reach the maximum output power of the terminal.
