First Claim
Patent Images
1. Method for coordinating access to a shared transmission medium in a Wireless Local Area Network (WLAN), comprising the steps of:
- identifying a station associated with a first basic service set (BSS);
determining a priority level dependent on a traffic pattern of the station based on a predetermined rule;
assigning sets of time slots dependent on the priority level, including;
a first set of time slots for a first priority level, anda second set of time slots for a second priority level, the second priority level being lower than the first priority level, the second set of time slots not including time slots of the first set of time slots; and
providing stations of the first priority level access opportunity in time slots within the first set and the second set of time slots, while denying access opportunity to stations of the second priority level within the first set of time slots.

Abstract
A method and apparatus for coordinating access to a shared transmission medium in a Wireless Local Area Network (WLAN), in order to minimize the risk for collisions. The method includes identifying a station associated with a first basic service set (BSS), and providing access opportunity to the station on the shared transmission medium in one or more time slots, which time slots are assigned dependent on a traffic pattern of the station.

8. Apparatus for coordinating access to a shared transmission medium in a Wireless Local Area Network (WLAN), the apparatus comprising:
-
an access point (AP) configured to provide radio communication with stations in basic service sets (BSS); a processor configured to execute program code; and a memory comprising instructions that when executed by the processor cause the apparatus to; determine a priority level dependent on a traffic pattern of the station based on a predetermined rule, assign sets of time slots dependent on the priority level, including; a first set of time slots for a first priority level, and a second set of time slots for a second priority level, the second priority level being lower than the first priority level, the second set of time slots not including time slots of the first set of time slots; and provide stations of the first priority level access opportunity in time slots within the first set and the second set of time slots, while denying access opportunity to stations of the second priority level within the first set of time slots. - View Dependent Claims (9, 10)

11. A computer program product for coordinating access to a shared transmission medium in a Wireless Local Area Network (WLAN), the computer program product comprising:
-
a non-transitory computer-readable medium comprising a set of codes for causing a computer to; determine a priority level dependent on a traffic pattern of the station based on a predetermined rule; assign sets of time slots dependent on the priority level, including; a first set of time slots for a first priority level, and a second set of time slots for a second priority level, the second priority level being lower than the first priority level, the second set of time slots not including time slots of the first set of time slots; and provide stations of the first priority level access opportunity in time slots within the first set and the second set of time slots, while denying access opportunity to stations of the second priority level within the first set of time slots.
