15 Claims

1. A power control method, comprising:

configuring, by a first communication node, an association between at least one first power control parameter for uplink transmission and sounding reference signal information; and

sending, by the first communication node, an indication indicating a sounding reference signal of the uplink transmission to a second communication node,

wherein the indication and the association are used by the second communication node to determine at least one second power control parameter for the uplink transmission, and

wherein for a non codebook based transmission, the association is between the first power control parameter and combinations of a plurality of sounding reference signal resource resources, and

wherein the at least one first power control parameter comprises an open-loop power control parameter, a path loss measurement parameter, and a closed-loop power control process index.
