Abstract: Embodiments provide a method for accessing an access point by a station device, a device, and a system. A station device selects a master access point from multiple access points according to channel quality and accesses the master access point, and sends information about remaining access points to the master access point, so that the master access point selects a slave access point according to the information about the remaining access points. In this way, the master access point coordinates with the slave access point to perform data transmission with the station device.

Abstract: 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.
