Problems solved by technology

[0006] In the prior art, since the total power of the PUSCH is evenly distributed among all ports configured on the network side corresponding to the corresponding transmission mode, when the terminal equipment (User Equipment, UE) only uses some ports to transmit the PUSCH (for example, only When using a non-zero port to transmit PUSCH), it will cause the uplink power allocated to other ports to be wasted, so that the total uplink power of PUSCH is not fully utilized, affecting the uplink coverage and uplink transmission rate of PUSCH

Abstract

The invention provides an uplink power control method and equipment. The method comprises the following steps of tRANSMITTING DOWNLINK CONTROL INFORMATION DCI, wherein the DCI comprises related parameters of uplink signal power control, the related parameters are related to the number of target ports of terminal equipment, or the related parameters are related to the number of the target ports ofthe terminal equipment and the total number of the ports, and the target ports are ports, used for transmitting the uplink signals, of the terminal equipment, wherein the uplink signal comprises at least one of a physical uplink shared channel (PUSCH) and a sounding reference signal (SRS). According to the embodiment of the invention, as related parameters of uplink signal power control included in DCI is related to the number of target ports practically used for transmitting the uplink signal in the terminal equipment, the uplink power can be controlled more accurately and reasonably, and theactual uplink total power of the uplink signal is increased, so that the uplink coverage and the uplink transmission rate of the uplink signal are improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and more particularly to an uplink power control method and device. Background technique [0002] Power control is an important technology in the wireless communication system, and the power control can make the wireless signal reach the receiver with reasonable power. [0003] In the fifth generation (5 th -Generation, 5G) mobile communication system, the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) supports two transmission modes based on codebook and non-codebook. In any of the two transmission modes, for a PUSCH, its uplink power is evenly distributed among all antenna ports (hereinafter referred to as ports) corresponding to the transmission mode, wherein the ports corresponding to the transmission mode may include Zero ports and non-zero ports. And for an uplink partial bandwidth b on a carrier f of a serving cell c, the uplink power (total uplink...
