Method for Obtaining Request of Station, Access Point, and Station

A method, wherein the method comprises:

• receiving, by a station from an access point, a control frame, wherein the control frame comprises device indication information and allocation information of available channels, wherein the device indication information indicates a to-be-scheduled station, and wherein the allocation information comprises information about a used-for-scheduling channel allocated to each to-be-scheduled station and information about a random competition channel allocated to a non-to-be-scheduled station;
• determining, by the station according to the device indication information, whether the station is the to-be-scheduled station;
• determining, by the station, a corresponding used-for-scheduling channel according to the allocation information of the available channels and sending a request to send frame using the used-for-scheduling channel, in response to determining that the station is the to-be-scheduled station;
• and
• selecting, by the station, at least one idle channel or idle sub-channel from the random competition channel according to the allocation information of the available channels and sending a request to send frame using the at least one idle channel or idle sub-channel, in response to determining that the station is not the to-be-scheduled station.

An access point, wherein the access point comprises:

• a processor;
• and
• a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to:
• construct a control frame, wherein the control frame comprises device indication information and allocation information of available channels, wherein the device indication information indicates a to-be-scheduled station of to-be-scheduled stations, and wherein the allocation information comprises information about a used-for-scheduling channel allocated to the to-be-scheduled station and information about a random competition channel allocated to a not-to-be-scheduled station;
• and
• send the control frame to a station.

A station, wherein the station comprises:

• a processor;
• and
• a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to:
• receive, from an access point, a control frame, wherein the control frame comprises device indication information and allocation information of available channels, wherein the device indication information indicates a to-be-scheduled station of to-be-scheduled stations, and wherein the allocation information comprises information about a used-for-scheduling channel allocated to the to-be-scheduled station and information about a random competition channel allocated to a non-to-be-scheduled station;
• determine, according to device indication information, whether the station is the to-be-scheduled station;
• determine a corresponding used-for-scheduling channel according to the allocation information of the available channels, in response to that the station is the to-be-scheduled station;
• and
• select at least one idle channel or idle sub-channel from the random competition channel according to the allocation information of the available channels, in response to determining that the station is a not-to-be-scheduled station.
