Abstract
The present application discloses an uplink LBT channel detection method, an uplink data sending method, and a device. The method includes: before transmitting a UL grant, determining, by a base station, based on a service priority in a BSR of user equipment scheduled in a self-contained subframe, a contention window required for performing LBT; and performing, by the base station, the LBT based on the contention window, and after detecting that a channel is idle, transmitting, in the self-contained subframe through the channel, a UL grant corresponding to the user equipment; or after detecting, by using the LBT, that a channel is idle, transmitting, by the base station in the self-contained subframe through the channel, a UL grant corresponding to the user equipment, where the UL grant carries information about the contention window, so that the user equipment performs the LBT based on the information about the contention window.
