Sounding reference signals with collisions in asymmetric carrier aggregation
摘要
說明書
In a second option, the UE may determine whether to interrupt the uplink transmission on CC1 or CC3 based on the channel or the information being sent. The UE may apply a prioritization rule similar to those presented in determining whether to transmit the uplink transmission or SRS. However, the prioritization rule may be applied to determine what information has a higher priority and therefore should not be interrupted to transmit the SRS. The CC having the lower priority information may then be selected for switching to CC2 to transmit the SRS. For example, if an ACK is going to be transmitted in CC1 and PUSCH will be transmitted in CC3, the UE may determine to interrupt the PUSCH of CC3 in order to transmit the SRS on CC2. If the same type of information is being transmitted on both CCs, the UE may then select between the two CCs based on the carrier number, as described in the first option. For example, if both CC1 and CC3 will transmit PUSCH, the UE may interrupt the carrier with a higher index number.
