Abstract: Methods, systems, and devices are described for wireless communication at an access point (AP). A scheduling procedure for using a full duplex wireless local area network (WLAN) AP with legacy station (STA) compatibility (e.g., half duplex) may be implemented. For example, a system may include a full duplex AP and have half duplex STAs with two antennas each. The scheduling procedure may involve dynamic grouping of STAs into half duplex sets, for example, based at least in part on location information of the STAs. The STAs may be grouped such that the AP is able to transmit to one of the half duplex sets while concurrently receiving from another of the half-duplex sets. The AP may employ beamforming, via the STAs, to reduce interference between full duplex in-band communications.

Abstract: Certain aspects of the present disclosure generally relate to position tracking of user equipment (UEs) using physical random access channel (PRACH) signals. According to certain aspects, a method is provided for wireless communications which may be performed, for example, by a base station (BS). The method generally includes communicating resources allocated for a physical random access channel (PRACH), a preamble sequence to be transmitted by a user equipment (UE) in the PRACH, and frame reference timings to neighboring cells; using a template based detector for PRACH to compute a timing advance using a shifted sequence that is closest to a profile of the preamble sequence received in the PRACH, and computing a first distance to the UE based on the computed timing advance.

Abstract: Systems and methods are disclosed for dynamically determining whether to sound a channel to determine new beamforming weights for use in MU-MIMO communication systems. A wireless station may receive a beamformed data communication from a wireless device such as a beamformer. The station may determine an indication of channel throughput from the beamformed data communication, and compare the indication of channel throughput to a threshold. If the indication of channel throughput is below the threshold, this may indicate that the beamforming weights are stale, and the wireless device may transmit a notification of stale beamforming weights to the beamformer. The beamformer may then determine whether to sound the channel to determine new beamforming weights.
