Abstract: Enhanced spatial reuse of radio spectrum in WLAN operation is described. An example of a storage medium includes instructions for connecting with multiple client devices at an access point in a basic service set (BSS) for transmission over a channel in a network environment; estimating a communication quality value for each of the client devices based at least in part on received signal strength values at the access point and at the client device; prioritizing spatial reuse operation based on the estimated communication quality values for the client devices; establishing a clear channel assessment (CCA) threshold for a spatial reuse operation in a transmission to a first client device, the first client device being selected based on an estimated communication quality value; and dynamically adjusting the CCA threshold based at least in part on success or failure of data transmission between the access point and the first client device.

Abstract: Examples described herein provide method and systems for high spatial reuse for mmWave Wi-Fi. Examples may include identifying, by a network device, a plurality of millimeter-wave (mmWave) propagation paths between the network device and a set of neighboring devices including a target neighboring device, based on power delay profiles (PDPs) of beam training frames received by the network device from each of the neighboring devices using a plurality of mmWave beams, and determining, by the network device for each of neighboring devices in the set, an estimated angle of arrival (AoA) of each identified mmWave propagation path between the network device and the neighboring device, based on the PDPs of the received beam training frames from the neighboring device. Examples may include selecting, by the network device, one of the mmWave beams that maximizes a signal to interference and noise ratio (SINR) along the estimated AoA of each identified mmWave propagation path between the network device and the target neighboring device, and communicating, by the network device, with the target neighboring device using the selected mmWave beam.
