Abstract:
Licensed assisted access (LAA) uplink (UL) transmissions can be performed using UL scheduling, enhanced node B (eNB) listen before talk (LBT), and user equipment (UE) LBT. A scheduling of a UE for UL transmission can include different procedures for a UE to perform LBT before UL transmission. These procedures can be classified as: i) a scheduled UE performing no LBT for UL transmission, ii) a scheduled UE performing fast LBT (as compared to the eNB) with a more aggressive choice of parameters than the eNB and iii) a scheduled UE performing LBT using parameters as used by the eNB for LBT. In some embodiments, the UL grant transmission by the eNB occurs in the unlicensed band after a successful LBT procedure at the eNB.

Claim (Index 1):
An apparatus of a user equipment (UE) for scheduling uplink channel access using a licensed assisted access (LAA) cell, comprising:\n a memory configured to store a counter value; a baseband processing unit configured to:\n receive a uplink grant scheduling a transmission and indicating a channel access procedure using the LAA cell; \n set the counter value to a random number between zero and a contention window value; \n sense the uplink channel of the LAA cell for a duration based at least in part on the counter value and an additional sensing duration, the additional sensing duration based at least in part on whether the uplink channel is idle during the sensing, \n detect the uplink channel of the LAA cell to be busy during the sensing the uplink channel; \n in response to detecting the uplink channel of the LAA cell to be busy, sense the uplink channel for the additional sensing duration; and \n enable access to the uplink channel of the LAA cell for the transmission using the LAA cell.
