Communication method, access point, and station

A communication apparatus comprising:

• a processor and;
• a memory for storing instructions which, when executed by the processor, cause the communication apparatus to:
• broadcast a sending request to a first station, wherein the sending request comprises a first bandwidth parameter, the first bandwidth parameter indicates an available bandwidth of the communication apparatus;
• receive a clear to send information from the first station in response to the sending request, wherein the clear to send information comprises a second bandwidth parameter, the second bandwidth parameter corresponds to a bandwidth required by the first station;
• allocate, in response to the available bandwidth being greater than the required bandwidth, the required bandwidth to the first station and remaining bandwidth in the available bandwidth to a second station;
• send trigger information to the first station on the required bandwidth;
• and
• send the trigger information to the second station on the remaining bandwidth.

A non-transitory computer readable storage medium, comprising computer-executable instructions which, when executed by a processor of a communication apparatus, cause the communication apparatus to:

• broadcast a sending request to a first station, wherein the sending request comprises a first bandwidth parameter, the first bandwidth parameter indicates an available bandwidth of the communication apparatus;
• receive a clear to send information from the first station in response to the sending request, wherein the clear to send information comprises a second bandwidth parameter, the second bandwidth parameter is corresponding to a bandwidth required by the first station;
• allocate, in response that the available bandwidth is greater than the required bandwidth, the required bandwidth to the first station and remaining bandwidth in the available bandwidth to a second station;
• send trigger information to the first station on the required bandwidth;
• and
• send the trigger information to the second station on the remaining bandwidth.
