Abstract
Provided is a transmission scheduling method based on station grouping, including performing physical grouping on stations into sectors based on positions of the stations, performing logical grouping of each physical group into logical groups based on a common characteristic of the stations in each physical group, transmitting, to the stations, access scheduling information used to enable each logical group to access an access point at different time intervals, and controlling a station access based on the access scheduling information.
Claims15
An operation method of an access point, the method comprising:
- performing physical grouping on stations into sectors based on positions of the stations;
- performing logical grouping on each physical group into logical groups, based on a common characteristic of the stations in each physical group;
- transmitting, to the stations, access scheduling information used to enable each logical group to access the access point at different time intervals;
- and
- controlling a station access based on the access scheduling information.
An operation method of an access point, the method comprising:
- grouping stations based on a common characteristic of the stations;
- dividing, into segments, each group in which the stations are grouped;
- transmitting, to the stations, access scheduling information used to enable the stations in sectors corresponding to the segments to access the access point at different time intervals;
- and
- controlling a station access based on the access scheduling information.
An operation method of a station, the method comprising:
- receiving access scheduling information from an access point;
- and
- accessing the access point based on the access scheduling information, and
- wherein the access scheduling information is used to enable the access point to group stations based on a common characteristic of the stations and divide, into segments, each group in which the stations are grouped, and enable the stations in sectors corresponding to the segments to access the access point at different time intervals.
