摘要： A wireless device is described that may selectively include resource allocation information in a frame to be transmitted to one or more other wireless devices. The resource allocation may indicate channel/sub-channel assignment for each wireless device. The wireless devices may each utilize this received resource allocation information to determine the appropriate segment/sub-band of the transmission that is intended for their receipt/consumption. A first signaling field (e.g., HE-SIG-A) may indicate whether the resource allocation information is present in a second signaling field (e.g., HE-SIG-B) of the frame. For example, a single bit may be toggled to indicate the presence of the second signaling field and therefore the presence of the resource allocation information. Alternatively, multiple bits may be used to indicate the length of the second signaling field (e.g., a length of zero indicates the absence of the second signaling field and accordingly the absence of the resource allocation information).

摘要： A method implemented by a first network device where the method provides an adaptive clear channel assessment (CCA) by collecting a neighboring network device set for a wireless local area network (WLAN). The method detects a wireless signal from a second network device on a wireless medium. A signal quality of the wireless signal is then determined. An identity of the second network device is also determined. The second network device is then added to the neighboring network device set of the first network device, in response to determining that the second network device is a neighbor based on the signal quality of the wireless signal.
