APERIODIC SRS FOR CARRIER AGGREGATION

摘要

A method of wireless communication includes receiving overlapping information triggering aperiodic sounding reference signal (SRS) transmission. The method also includes processing the overlapping information in accordance with the received triggering information. The overlapping information can be comprises consistent configuration information for the aperiodic SRS transmission, in which case the processing includes transmitting an aperiodic SRS in accordance with the configuration information. When the overlapping information has dissimilar configurations for the aperiodic SRS transmission; the processing includes treating the overlapping information as an error event. The overlapping information can be a trigger received in an uplink grant and a trigger received in a downlink grant. The wireless system can be a multicarrier system including multiple component carriers.
