Abstract

Certain aspects of the present disclosure provide techniques for handling collisions between PUSCH and sounding reference signal (SRS) on additional SRS symbols in an uplink subframe using carrier aggregation. The techniques provide rules that a user equipment (UE) may apply to decide if and when to drop or apply power scaling to SRS or PUSCH transmissions scheduled on overlapping time resources.
