1. A method for use in a user equipment (UE) of managing a listen-before-talk (LBT) contention window size, the method comprising:
receiving scheduling for a current burst of contiguous uplink subframes, the scheduling comprising, for each subframe of the burst of contiguous uplink subframes, an associated hybrid automatic repeat request (HARQ) process identifier and an associated new data indicator (NDI);
determining a reference subframe based on a previously-scheduled burst of contiguous uplink subframes, the reference subframe associated with a reference HARQ process identifier; and
when the UE determines the HARQ process identifier associated with at least one of the subframes of the current scheduled burst of contiguous uplink subframes matches the reference HARQ process identifier and the associated NDI indicates new data, resetting the LBT contention window size to a minimum value.
