Abstract
There is provided access to a communications channel in a wireless communications network. Stations (STAs) associated with an access point (AP) are grouped in at least two groups of STAs, each group being associated with a minimum transmission power level needed by the AP to communicate with the STAs in that group. A first time interval is allocated for a first group of STAs associated with highest minimum transmission power to access the communications channel concurrently with a third time interval being allocated by another AP for a third group of STAs associated with lowest minimum transmission power level needed by said another AP to communicate with the third group of STAs to access the communications channel. A second time interval, non-overlapping with the first time interval, is allocated for a second group of STAs associated with lowest minimum transmission power to access the communications channel concurrently with a fourth time interval being allocated by said another AP for a fourth group of STAs associated with highest minimum transmission power level needed by said another AP to communicate with the fourth group of STAs to access the communications channel.
