Abstract
Various aspects of the present disclosure generally relate to wireless communication. Some techniques and apparatuses described herein provide resolution of ambiguity with regard to determination of an open loop power control value (e.g., a P0 value) for a user equipment that is configured with at least two downlink control information formats, of which one is configured with a sounding reference signal resource indicator (SRI) field and another is not configured with an SRI field. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving downlink control information (DCI) for a physical uplink shared channel (PUSCH), wherein the DCI includes an indication of an open loop power level associated with the PUSCH,
- wherein the DCI includes a single-bit indication field for the open loop power level and a sounding reference signal resource indicator (SRI) field based at least in part on a DCI format of the DCI, and wherein the SRI field indicates a power parameter set including multiple open loop power levels;
- determining a lowest-indexed power level of the multiple open loop power levels as the open loop power level based at least in part on the single-bit indication field and the SRI field, wherein the lowest-indexed power level is configured to be associated with a power level larger than another power level of the multiple open loop power levels;
- and
- transmitting on the PUSCH using the open loop power level.

A method of wireless communication performed by a network entity, comprising:
- transmitting downlink control information (DCI) for a physical uplink shared channel (PUSCH), wherein the DCI includes an indication of an open loop power level associated with the PUSCH,
- wherein the DCI includes a single-bit indication field for the open loop power level and a sounding reference signal resource indicator (SRI) field based at least in part on a DCI format of the DCI, and wherein the SRI field indicates a power parameter set including multiple open loop power levels;
- and
- receiving on the PUSCH, wherein the open loop power level of the PUSCH uses a lowest-indexed power level of the multiple open loop power levels, wherein the lowest-indexed power level is configured to be associated with a power level larger than another power level of the multiple open loop power levels.
1 more element
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- receive downlink control information (DCI) for a physical uplink shared channel (PUSCH), wherein the DCI includes an indication of an open loop power level associated with the PUSCH,
- wherein the DCI includes a single-bit indication field for the open loop power level and a sounding reference signal resource indicator (SRI) field based at least in part on a DCI format of the DCI, and wherein the SRI field indicates a power parameter set including multiple open loop power levels;
- determine a lowest-indexed power level of the multiple open loop power levels as the open loop power level based at least in part on the single-bit indication field and the SRI field, wherein the lowest-indexed power level is configured to be associated with a power level larger than another power level of the multiple open loop power levels;
- and
- transmit on the PUSCH using the open loop power level.
5 more elements
A network entity for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- transmit, via downlink control information (DCI), scheduling information for a physical uplink shared channel (PUSCH), wherein the scheduling information indicates an indication of an open loop power level associated with the PUSCH,
- wherein a DCI format of the DCI includes a single-bit indication field for the open loop power level and a sounding reference signal resource indicator (SRI) field, and wherein multiple open loop power levels are configured for a power parameter set indicated by the SRI field;
- and
- receive on the PUSCH, wherein the open loop power level of the PUSCH uses a lowest-indexed power level of the multiple open loop power levels, and wherein the lowest-indexed power level is configured to be associated with a power level larger than another power level of the multiple open loop power levels.
