Abstract

A method for determining a power control parameter and a terminal. The method includes: in a case that no target parameter has been configured in power control parameters of a target object, determining a target parameter of the target object in any one of the following manners: determining, based on a target parameter of another object configured by a network device, the target parameter of the target object, where the another object is different from the target object; determining, based on a historical configuration, the target parameter of the target object; and determining, based on protocol specification, the target parameter of the target object; where the target object and the another object are selected from a physical uplink control channel PUCCH, a physical uplink shared channel PUSCH, and a sounding reference signal SRS.

Claims18

Dependent claims

A method for determining a power control parameter, applied to a terminal and comprising:

in a case that no pathloss reference reference signal of a sounding reference signal (SRS) has been configured,
determining, based on protocol specification, the pathloss reference reference signal of the SRS;
wherein the determining, based on protocol specification, the pathloss reference reference signal of the SRS comprises:
determining a first RS from configured downlink reference signals RSs as the pathloss reference reference signal;
wherein the first RS is a downlink RS in quasi co-location (QCL) information associated with the SRS;
wherein the SRS is located in a first carrier, and the downlink RS in the quasi co-location (QCL) information associated with the SRS comprises:
in a case that the first carrier is configured with no CORESET, and that an active bandwidth part (BWP) of the first carrier is configured with M transmission configuration indicators (TCIs) for PDSCH, a downlink RS in a first TCI, wherein the first TCI is a TCI with the lowest identification number in the M TCIs, the M TCIs are in an active state, wherein M is a positive integer.
