Abstract:
A method for performing listen-before-talk (LBT) on multiple unlicensed carrier includes: performing, by a station, an individual LBT mechanism on each of unlicensed carriers to be aggregated to obtain a right to use the each of the unlicensed carriers; or configuring, by the station, a same LBT mechanism for the unlicensed carriers to be aggregated, performing a unified LBT mechanism on each of the unlicensed carriers to be aggregated to obtain the right to use each of the unlicensed carriers; or grouping, by the station, the unlicensed carriers to be aggregated, performing a corresponding LBT mechanism on each group of unlicensed carriers to obtain a right to use the each group of unlicensed carriers.

Claim (Index 3):
The method according to  claim 1 , wherein performing, by a station, an individual LBT mechanism on each of unlicensed carriers to be aggregated to obtain a right to use the each of the unlicensed carriers comprises one of:\n in response to determining that the station performs the LBT mechanism on unlicensed carriers to be preempted and planned to be aggregated, using, by the station, a same random number N in random back-off of the unlicensed carriers to be aggregated preempted; in response to determining that extended Clear Channel Assessment (eCCA) detections of a plurality of unlicensed carriers simultaneously indicate idle, decrementing a value of N; and in response to determining that the value of N is 0, the plurality of unlicensed carriers are preempted by the station simultaneously; or determining, by the station, the unlicensed carriers to be preempted and planned to be aggregated, and performing LBT on the plurality of unlicensed carriers separately, and generating an independent random value N for each of the plurality of unlicensed carriers; in response to determining that the station successfully contends for one unlicensed carrier of the plurality of unlicensed carriers, the station including a priority in the preemption of an unlicensed carrier at a frequency point within a first preset range around the one unlicensed carrier for which the station successfully contended until the plurality of unlicensed carriers are preempted by the station; or in response to determining that the station already includes a right to use an unlicensed carrier and the station aggregates unlicensed carriers at a frequency point within a second preset range around the unlicensed carrier, the station including a priority in the preemption for aggregating the unlicensed carriers at the frequency point within the second preset range, until the plurality of unlicensed carriers are preempted by the station; or in response to determining that the station performs the LBT on the unlicensed carriers to be preempted and planned to be aggregated and an interval from preempting one unlicensed carrier of the unlicensed carriers to be preempted by the station to a moment of successful preemption is less than or equal to a third preset range, initiating, by the station, clear channel assessment (CCA) detections on other unlicensed carriers to be aggregated, in response to determining that consecutive eCCA detections within the third preset range all indicate idle, the station including the right to use the one unlicensed carrier; proceeding to perform by the station the eCCA detections on the unlicensed carrier which includes an interval of being preempted successfully within the third preset range, and in response to determining that consecutive eCCA detections within the third preset range all indicate idle, the station including the right to use the unlicensed carrier.
