The UE may adjust the uplink transmission by shortening the uplink transmission on the second CC at 1222 to a subset of uplink symbols of the subframe or a subset of subframes when the SRS transmission in the uplink portion of the first CC would at least partially collide with the uplink transmission on the second CC and when the interruption time meets a threshold. The UE may then transmit the SRS at 1216 and transmit the adjusted/limited uplink transmission at 1212. The UE may puncture the uplink transmission on the second CC at 1228 with the SRS transmission in the uplink portion of the first CC when the interruption time meets the threshold. The uplink transmission on the second CC at 1212 may comprise a shortened uplink format to accommodate the puncturing transmission of the SRS in the subframe. The uplink transmission may comprise a PUSCH, so that the PUSCH transmission is limited to a subset of the uplink symbols of the subframe. A PUSCH may also be adjusted based, at least in part, on subframe configuration, or restriction, of the second CC. Thus, the PUSCH may be restricted to selected, configured, subframes of the second CC, or the PUSCH may use a shortened UCI format when the interruption time is below a threshold.

The UE may refrain from switching to the first CC to transmit the SRS when the SRS would at least partially collide with the uplink transmission on the second CC, wherein the performing comprises transmitting the uplink transmission on the second CC.

The UE may adjust reception of the downlink transmission by refraining from receiving at least a portion of the downlink transmission on the second CC at 1224 when the downlink transmission would at least partially collide with the SRS. The UE may then transmit the SRS in the uplink portion of the first CC at 1216.
