Abstract

Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable for multi-band operation in a plurality of frequency bands, each frequency band comprising one or more channels. The AP may select a subset of the frequency bands for which the AP is to request per-band channel availability information from the STA. The AP may transmit a Trigger Frame (TF) for a multi-band bandwidth query report polling (MB-BQRP) to request the per-band channel availability information. The AP may receive an uplink frame that includes a multi-band bandwidth query report (MB-BQR) that indicates the per-band channel availability information. The AP may determine, based on the MB-BQR, for an uplink transmission by the STA: one or more frequency bands of the subset of frequency bands, and one or more corresponding channels.
