DATA TRANSMISSION METHOD AND APPARATUS

摘要

The present invention discloses a data transmission method and apparatus. A first access point determines a current working uplink receiving beam, and broadcasts an identifier of the current working uplink receiving beam of the first access point, so that when a first station associated with the first access point determines, according to the identifier of the current working uplink receiving beam of the first access point, that a first transmitting beam at which the first station is currently working is the current working uplink receiving beam of the first access point, the first station performs data transmission with the first access point by using the first transmitting beam. The current working uplink receiving beam of the first access point and a current working uplink receiving beam of a second access point do not overlap in space, thereby reducing interference during data transmission and improving spectral usage efficiency.
