Abstract
This application discloses a power control method and apparatus, and user equipment. The method includes: receiving, by UE, DCI, where the DCI is used to schedule PUSCH transmission; the PUSCH transmission is associated with different target resources; and the target resource includes: an SRS resource or an SRS resource group; and determining, based on the DCI, a target power control parameter corresponding to the PUSCH transmission. Embodiments of this application are applied to power adjustment scenarios.
Claims20
A power adjustment method, wherein the method comprises:
- receiving, by user equipment (UE), downlink control information (DCI), wherein the DCI is used to schedule physical uplink shared channel (PUSCH) transmission;
- the PUSCH transmission is associated with different target resources;
- and the target resource comprises a plurality of sounding reference signal (SRS) resources, wherein the plurality of SRS resources come from different SRS resource sets;
- determining at least one set of first power control parameters in a case that the DCI contains no SRS resource indicator SRI field, the at least one set of first power control parameters comprises a parameter indicating at least one set of pathloss reference signals, the at least one set of pathloss reference signals is determined based on multiple sets of pathloss reference signals indicated by a plurality of consecutive indexes starting from a first preset index;
- and
- determining, based on the DCI, a target power control parameter corresponding to the PUSCH transmission, wherein the target power control parameter is a power control parameter in the at least one set of first power control parameters.
UE, comprising a processor, a memory, and a program or instructions stored in the memory and capable of running on the processor, wherein when the program or instructions are executed by the processor, the following steps are implemented:
- receiving DCI, wherein the DCI is used to schedule PUSCH transmission;
- the PUSCH transmission is associated with different target resources;
- and the target resource comprises a plurality of SRS resources, wherein the plurality of SRS resources come from different SRS resource sets;
- determining at least one set of first power control parameters in a case that the DCI contains no SRS resource indicator SRI field, the at least one set of first power control parameters comprises a parameter indicating at least one set of pathloss reference signals, the at least one set of pathloss reference signals is determined based on multiple sets of pathloss reference signals indicated by a plurality of consecutive indexes starting from a first preset index;
- and
- determining, based on the DCI, a target power control parameter corresponding to the PUSCH transmission, wherein the target power control parameter is a power control parameter in the at least one set of first power control parameters.
