Abstract: Embodiments of the present disclosure provide a backoff window adjustment method, and an apparatus. In downlink transmission, a base station obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the base station on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel. In uplink transmission, a user equipment (UE) obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the UE on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel.

Abstract: Embodiments of the present invention provide an unlicensed spectrum-based wireless communication method, a base station, and a terminal device. The method includes: occupying, by a base station, a first carrier on an unlicensed spectrum by using a first clear channel assessment CCA, where the first CCA is a single-slot CCA; sending, by the base station, first indication information to a terminal device, where the first indication information is used to instruct the terminal device to send uplink information to the base station on the first carrier; and receiving, by the base station on the first carrier, the uplink information from the terminal device. In the embodiments of the present invention, utilization of an unlicensed spectrum resource can be improved.
