An access point (AP) for basic service set (BSS) coverage scaling, providing scaled coverage, comprises: determining BSS overlap 405, causing operation in a reduced coverage mode with power reduction 415, generating a beacon comprising an indication of a reduced coverage mode in a capability field and one or more coverage scaling parameters (CSP) in an information element 420, and causing the beacon to be provided to one or more stations (STA) 430. A station receiving the beacon will cause transmission of uplink (UL) communications in accordance with the CSP. An indication of a calculated power transmission reduction is provided in the CSP, wherein the CSP comprise one or more of a relative transmission (TX) power reduction, an indication of whether a current frame is transmitted with a maximum or current power, an indication of whether stations (STAs) are required to scale TX power, or an indication of which tower or sector identification (ID) to which the parameter set applies 425. An indication of the duration of the coverage scaling is also provided in the CSP. Invention may be applied to an Overlapping Basic Service Set (OBSS) situation to reduce or eliminate the overlapping coverage by scaling coverage, through coordination of coverage areas between APs. |
