Systems and methods for handling of an uplink transmission collision with an ACK/NACK signal are provided. The scheduled uplink transmission is refrained due to the collision. Subsequent non-adaptive retransmission for the scheduled uplink transmission may be refrained by delivering an ACK for the scheduled uplink transmission to high layers. Alternatively, subsequent non-adaptive retransmission for the scheduled uplink transmission may be refrained by setting the HARQ feedback for the scheduled transmission to ACK. In some implementations, a subsequent non-adaptive retransmission for the scheduled uplink transmission may be transmitted. If a subsequent non-adaptive retransmission is to be transmitted, the HARQ redundancy version for the subsequent non-adaptive retransmission is refrained from incrementing from the original redundancy version for the scheduled uplink transmission.
