Abstract: Embodiments of a station (STA) and method for communication in accordance with phase noise compensation are generally described herein. The STA may determine, based at least partly on one or more operational parameters, whether to perform phase noise compensation of data symbols of a received protocol data unit (PDU). For instance, the STA may compare the operational parameters with one or more thresholds. The STA may further determine a method of phase noise compensation based at least partly on one or more operational parameters. As an example, the STA may determine a type of interpolation to be used for an interpolation of phase noise estimates of pilot symbols to determine phase noise estimates of data symbols. Example operational parameters may include a signal quality metric, a carrier frequency offset (CFO) measurement and/or modulation and coding scheme (MCS).

Abstract: In a radio-access network utilizing beam-formed communications, beam direction for uplink or downlink communications is determined based on learned beam directions applicable to a current location of user equipment (UE) in lieu of a sector scan when prior transmission performance measures are available for the current location. A beam-finding map that associates a plurality of locations with corresponding beam directions previously determined to be operative to direct transmission from those locations to a recipient device is used.

Abstract: Embodiments of a WLAN sensing frame exchange protocol are generally described herein. In some embodiments, a wireless communication device is configured to perform a WLAN sensing protocol within a basic service set (BSS) comprising one or more stations (STAs) (STA1 and STA2) including an access point station (AP STA). The WLAN sensing protocol comprises a discovery phase, a negotiation phase, a measurement phase, and a reporting phase. To perform the WLAN sensing protocol, the wireless communication device is configured to operate as either a sensing initiator or a sensing responder, and to operate as a sensing transmitter and/or a sensing receiver. Some 60 GHz embodiments relate to WLAN sensing in a PBSS or IBSS with DMG STAs.
