Data Transmission Method and Apparatus

A data transmission method, comprising:

• receiving, by a first station, an identifier of a current working uplink receiving beam of a first access point, the identifier being broadcast by a first access point, wherein the first station is associated with the first access point;
• and
• performing, by the first station, data transmission with the first access point by using a first transmitting beam when the first station determines, according to the identifier of the current working uplink receiving beam of the first access point, that the first transmitting beam at which the first station is currently working is the current working uplink receiving beam of the first access point;
• wherein 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;
• wherein a reception area of the first access point comprises at least two reception subareas, and each reception subarea serves as one uplink receiving beam;
• and
• wherein a signal coverage area of the first access point and a signal coverage area of the second access point have an overlapping part.

A data transmission apparatus, wherein the apparatus is a first access point and comprises:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
• determine a current working uplink receiving beam of the first access point, wherein 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, wherein a reception area of the first access point comprises at least two reception subareas, and each reception subarea serves as one uplink receiving beam, and wherein a signal coverage area of the first access point and a signal coverage area of the second access point have an overlapping part;
• and
• broadcast an identifier of the current working uplink receiving beam of the first access point, so that when a first station that is 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.

A data transmission apparatus, the apparatus being first station, wherein the apparatus comprises:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to
• receive an identifier, which is broadcast by a first access point, of a current working uplink receiving beam of the first access point, wherein the first station is associated with the first access point;
• determine, 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;
• and
• perform data transmission with the first access point by using the first transmitting beam;
• wherein 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;
• wherein a reception area of the first access point comprises at least two reception subareas, and each reception subarea serves as one uplink receiving beam;
• and
• wherein a signal coverage area of the first access point and a signal coverage area of the second access point have an overlapping part.
