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 26):
A computer program product comprising a computer-readable storage medium that stores instructions for execution by a processor to perform operations of a User Equipment (UE) for uplink channel access procedure of a licensed assisted access (LAA) cell, the operations, when executed by the processor, to perform a method, the method comprising:\n receive an uplink grant scheduling a physical uplink shared channel (PUSCH) transmission that indicates a channel transmission procedure using a carrier of a LAA channel of the LAA cell; set a decrementing counter value to a random number between zero and a contention window value; determine, based on input from RF circuitry, the LAA channel to be idle during slot durations of a duration indicated by the decrementing counter value; detect that the decrementing counter value has reached zero; generate the PUSCH transmission for transmission on the carrier of the LAA cell.
