Abstract: Methods and apparatus are provided for fast transmission by a UE of scheduling requests for low latency data transmission. When transmit data for transmission on an uplink shared channel arrives, the UE determines whether the scheduling request to be sent by the user equipment to request uplink resources for transmission of the data will overlap a scheduled data transmission. If it is determined that the scheduling request will overlap the scheduled data transmission, the UE may preempt the scheduled data transmission to transmit the scheduling request. Preemption may be based on one or more predetermined criteria including the priority of the new transmit data, the periodicity of the scheduling request interval, and the remaining duration of the ongoing data transmission.
