Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may determine a number of uplink timing groups configured for a plurality of component carriers, and determine whether to transmit at least one of data or control information on one or more first component carriers of the plurality of component carriers concurrently with sounding reference signals (SRS) on one or more second component carriers of the plurality of component carriers based at least in part on the number of uplink timing groups. When only one uplink timing group is determined, the SRS is transmitted in a symbol on the one or more second component carriers if the data and control information is not transmitted in the symbol. When two uplink timing groups are determined SRS may be transmitted on the second component carriers concurrently with data or control information on the component carriers.
