Sounding reference signals with collisions in asymmetric carrier aggregation
摘要
說明書
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus receives a CA configuration for a first CC and a second CC, the first CC being a TDD CC, the CA configuration including downlink portions and excluding uplink portions of the first CC for data transmission by the UE to transmit uplink data, e.g., PUSCH. The apparatus determines to transmit an uplink transmission on the second CC in a subframe or to receive a downlink transmission in the subframe on the second CC and determines that a transmission of a SRS in an uplink portion of the first CC would at least partially collide in the subframe with either the uplink transmission or the downlink transmission. The apparatus then determines 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 based on an interruption time to transmit the SRS in the uplink portion of the first CC. Based on the determination to adjust, the apparatus performs at least one of transmitting the uplink transmission on the second CC, receiving the downlink transmission on the second CC, or transmitting the SRS in the uplink portion of the first CC.
