Abstract: The invention relates to a user equipment for being scheduled with uplink radio resources. The user equipment receives from a radio base station a first-stage uplink resource scheduling message, indicating uplink radio resources usable by the UE to perform an uplink transmission via an unlicensed cell. The receiver further receives a second-stage uplink resource scheduling message, which is related to the first-stage uplink resource scheduling message. Upon reception of the second-stage uplink resource scheduling message, a processor of the UE determines that an uplink transmission is scheduled in case the first-stage uplink resource scheduling message is valid. The first-stage uplink resource scheduling message is determined valid based on a determination as to whether an uplink transmission has been triggered by another second-stage uplink resource scheduling message within a predetermined time period prior to reception of the second-stage uplink resource scheduling message.

Abstract: Methods, systems, and devices for wireless communications are described. Some systems may support the transmission of a predicted negative acknowledgment (NACK) indication for a downlink data message. In some cases, a base station may transmit a downlink data message to a user equipment (UE). The UE may perform a decoding process for the message. The UE may determine whether the decoding process is likely to fail during a first portion of the decoding process prior to completion of the decoding process. The UE may transmit a predicted NACK message to the base station prior to a feedback opportunity configured for the UE to transmit feedback based on a result of the completed decoding process. The base station may determine whether to retransmit the downlink data message based on the predicted NACK message, such that the predicted NACK message may reduce the latency associated with retransmission of downlink data messages.
