Abstract
A method is carried out on a device capable of utilizing a high efficiency wireless local area network (HEW) communication protocol and a legacy communication protocol, and includes wirelessly receiving a communication frame; when the measured energy level of the frame exceeds a static clear channel assessment (CCA) energy level, identifying the BSS to which the frame corresponds, wherein identifying the BSS to which the frame corresponds comprises utilizing a BSS identifier included in the frame when the frame is an HEW frame or utilizing a MAC address included in the frame when the frame is a legacy frame; when the frame corresponds to the same BSS as the device, processing the frame utilizing the static CCA energy level; and when the frame corresponds to an overlapping OBSS, processing the frame utilizing a dynamic CCA energy level.
