US 2026/0239221 A1 · OPEN LOOP POWER CONTROL ENHANCEMENTS FOR SINGLE DOWNLINK CONTROL INFORMATION BASED SIMULTANEOUS PHYSICAL UPLINK SHARED CHANNEL TRANSMISSIONS

Abstract

Power control enhancements for cases using a single downlink control information (DCI) to schedule simultaneous physical uplink shared channels (PUSCHs) sent on separate antenna panels of a user equipment (UE) are discussed herein. In some embodiments, a DCI includes one or more sounding reference signal (SRS) resource indicators (SRIs) that are applied with respect to one or more SRI-indexed power control lists for the antenna panels to determine an open loop transmit power factor for each of two simultaneous PUSCHs. In some embodiments, a DCI includes one or more transmit power control (TPC) commands that are applied with respect to stored closed loop transmit power factors for the antenna panels to determine a closed loop transmit power factor for each of two simultaneous PUSCHs. Dynamic point selection (DPS) use in these contexts is also discussed. Power scaling for simultaneous PUSCHs is also discussed.

Dependent claims

A method of a user equipment (UE) having a first antenna panel and a second antenna panel, comprising:

receiving, from a network, one or more sounding reference signal (SRS) resource indicator (SRI)-indexed power control lists;
receiving, from the network, a downlink control information (DCI) scheduling a first physical uplink shared channel (PUSCH) on the first antenna panel and a second PUSCH on the second antenna panel that is simultaneous with the first PUSCH, the DCI comprising one or more SRIs;
determining a first open loop transmit power factor for the first PUSCH and a second open loop transmit power factor for the second PUSCH by applying the one or more SRIs to the one or more SRI-indexed power control lists;
and
simultaneously transmitting, to the network, the first PUSCH on the first antenna panel using a first transmit power that is based on the first open loop transmit power factor and the second PUSCH on the second antenna panel using a second transmit power that is based on the second open loop transmit power factor.
