SOUNDING REFERENCE SIGNALS IN ASYMMETRIC CARRIER AGGREGATION

摘要

Sounding reference signal (SRS) transmission is disclosed for asymmetric carrier aggregation, where the carrier aggregation occurs using multiple component carriers that include both paired and at least one non-paired component carrier. A user equipment (UE) determines whether to transmit SRS over at least one of the non-paired component carriers. The UE transmits the SRS over the non-paired component carrier when the determination is made. The UE maintains a single component carrier transmission at a time with a single carrier waveform SRS transmission by transmitting the SRS on a different component carrier at different subframes.
