Aperiodic SRS for carrier aggregation
First Claim
1. A method of wireless communication for a single device in a wireless system, comprising:
- receiving overlapping triggers, the overlapping triggers each comprising information triggering an aperiodic sounding reference signal (SRS) transmission on a particular component carrier, the information received from different grants received from at least one serving base station; and
processing the overlapping triggers in accordance with the information, wherein processing the overlapping triggers comprises interpreting the overlapping triggers as an error event such that no aperiodic SRS transmission occurs.

Abstract
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 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.
