Sounding reference signals with collisions in asymmetric carrier aggregation
摘要
說明書
When the UE determines that the transmission of the SRS in the uplink portion of the first CC would at least partially collide with the uplink transmission or reception of the downlink transmission, the UE determines at 1210 to adjust at least one of the uplink transmission, the SRS transmission, or reception of the downlink transmission based on the determination of the collision and an interruption time to transmit the SRS in the uplink portion of the first CC. The interruption time may comprise, e.g., an amount of time required to switch from the second CC to the first CC in order transmit the SRS.
After determining the adjustment to be made, the UE then performs at least one of transmitting the uplink transmission on the second CC at 1212, receiving the downlink transmission on the second CC at 1214, or transmitting the SRS at 1216 in the uplink portion of the first CC based on the determination to adjust. The transmission of the SRS in the uplink portion of the first CC, at 1216, may include switching, at 1218, from the second CC to the first CC. Thus, the interruption time may be based on the interruption time due to switching from the second CC to the first CC to transmit the SRS.
The UE may adjust the transmission of the SRS in the uplink portion of the first CC by dropping the transmission of the SRS at 1220 when the SRS would at least partially collide with the uplink transmission on the second CC. The UE may then transmit the uplink transmission on the second CC.
