Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for passive beamforming for Wi-Fi. A first wireless device communicating in an active session via a first bandwidth with a second wireless device may use a passive beamforming technique to identify a transmission sector of the second wireless device and/or a receive sector for communications on a second bandwidth, while the first wireless device is in an inactive session state for the second bandwidth. The second wireless device may transmit beacons in the second bandwidth via directional transmission sectors while the first wireless device is in the inactive session state for the second bandwidth. The first wireless device may receive the beacons and may select a transmission sector based on the beacons. The first wireless device may indicate the selected transmission sector to the second wireless device. The first wireless device may select a receive sector based on the beacons.

Abstract: Certain aspects of the present disclosure provide techniques for sending a retransmission of codewords of a data packet to a receiver node, that were not previously successfully received by the receiver node, in a manner compatible with a receive capability constraint of the receiver node.
