Abstract

The invention provides a power control method, a network equipment and a terminal. The power control method comprises the following steps of: configuring power control parameters for resources in a set of uplink beam management resources for an uplink beam management procedure; and transmitting the power control parameters to a terminal to cause the terminal to transmit the resources in the set ofuplink beam management resources according to the power control parameters. According to the power control method, the power control of resources in the set of uplink beam management resources for the uplink beam management procedure is achieved, and the signaling overhead of power control of the uplink beam management resources for the uplink beam management procedure can be controlled.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a power control method, network equipment and a terminal. Background technique [0002] In traditional fourth generation mobile communication technology (4th Generation, 4G) mobile communication systems, Sounding Reference Signal (Sounding Reference Signal, SRS) is mainly used for uplink or downlink channel state information (Channel State Information, CSI) acquisition. Specifically, the terminal, such as user equipment (UserEquipment, UE), transmits the SRS power on subframe i as: [0003] P SRS (i)=min{P CMAX ,P SRS_OFFSET +10log 10 (M SRS )+P O_PUSCH (j)+α(j)·PL+f(i)} [0004] Among them, P CMAX Indicates the maximum transmission power configured by the UE; [0005] P SRS_OFFSE Indicates the semi-static UE parameters configured by the upper layer, divided into two cases, if K S =1.25,P SRS_OFFSE The range is [-3,12]db, the step size is 1db; if K ...
