HARQ ID for consecutive uplink subframes in a wireless device

Abstract:

A wireless device receives an uplink grant for consecutive subframes. The uplink grant indicates: a number of the consecutive subframes comprising a starting subframe and an ending subframe; and a hybrid automatic repeat request process number (HARQ ID). LBT(s) are performed for transmitting via the consecutive subframes. A packet is transmitted via a first subframe of the consecutive subframes according to a first HARQ ID. The first HARQ ID is equal to ((the HARQ ID plus i) modulo a first pre-configured number). i indicates a subframe position of the first subframe in the consecutive subframes. i is equal to zero for the starting subframe and i is equal to the number minus one for the ending subframe, regardless of an outcome of the LBT(s) for any subframe of the consecutive subframes before the first subframe.
