Abstract

Certain aspects of the present disclosure provide techniques for scaling transmission power across transmit chains for physical uplink shared channel (PUSCH) transmissions. In some cases, a UE may determine a transmit power budget, receiving signaling indicating how to allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, and transmitting the PUSCH using the transmit chains according to the determined transmit power allocation.
