Abstract

Embodiments of this disclosure provide a contention window adjustment method and apparatus and a communication system. The method includes: transmitting first data by a transmitting device on a carrier, the carrier including two or more bandwidth units; and adjusting a contention window (CW) associated with a bandwidth unit to which the first data correspond by the transmitting device. With the method of the embodiment of this disclosure, in a case where data (referred to as first data) are transmitted on a carrier including two or more bandwidth units (such as a BWP / LBT sub-band / LBT channel), by adjusting the CW associated with the bandwidth unit to which the data correspond, a problem that the existing CW adjustment method is inapplicable to a scenario where a carrier corresponds to two or more bandwidth units may be solved.
