The embodiments of the present disclosure provide a method for processing an LBT parameter, a method for adjusting a contention window and associated apparatuses. The method for processing an LBT parameter includes: generating, by a first station, an LBT parameter comprising a parameter used by the first station to perform LBT for unlicensed carriers and/or indicating a parameter used by a second station receiving the LBT parameter to perform LBT for the unlicensed carriers; and transmitting, by the first station, the LBT parameter. With the embodiments of the present disclosure, the problem associated with interference due to unlicensed carrier contention by neighboring stations can be solved, such that the interference between the neighboring stations due to unlicensed carrier contention by the neighboring stations can be avoided.
