HYBRID COORDINATION FUNCTION (HCF) ACCESS THROUGH TIERED CONTENTION AND OVERLAPPED WIRELESS CELL MITIGATION

摘要

A method and system reduce interference between overlapping first and second wireless LAN cells in a medium. Each cell includes a respective plurality of member stations and there is at least one overlapped station occupying both cells. An inter-cell contention-free period value is assigned to a first access point station in the first cell, associated with an accessing order in the medium for member stations in the first and second cells. The access point transmits a beacon packet containing the inter-cell contention-free period value, which is intercepted at the overlapped station. The overlapped station forwards the inter-cell contention-free period value to member stations in the second cell. A second access point in the second cell can then delay transmissions by member stations in the second cell until after the inter-cell contention-free period expires.

1. A method for reducing an interference between overlapping first and second wireless cells in a medium, each wireless cell including a respective plurality of member stations and an overlapped station occupying both wireless cells, comprising:
assigning an inter-cell contention-free period having a value to a first access point station of the plurality of member stations in the first wireless cell, wherein the value is associated with an accessing order in the medium for member stations in the first and second wireless cells; and transmitting by the first access point station in the first wireless cell, a beacon packet containing the value, wherein the beacon packet is transmitted to the overlapped station for allowing the overlapped station to forward the value to a second access point station of the member stations in the second wireless cell.
