Abstract: Sector sweeps are described for establishing two-way data communications with directional antennas. Some examples receive a sequence of base station transmit sector sweep signals from a base station (BS) at the UE, each signal being transmitted to a different transmit sector from a multiple antenna array of the BS, select a best transmitted signal at the UE from among the received signals, send a sequence of UE transmit sector sweep signals to the base station from the UE, each signal being transmitted to a different transmit sector from a multiple antenna array of the UE, send an identification of the selected best base station transmit sector sweep signal to the base station, receive an identification of a selected best UE transmit sector sweep signal from the base station, and send data to the BS using the identified best UE transmit sector.

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: A radio communication device includes a plurality of antenna arrays each configured to generate a steerable antenna beam according to a respective beamforming codeword, wherein each of the plurality of antenna arrays is configured to obtain the respective beamforming codeword from a single-antenna-array steering codebook that is reused by each of the plurality of antenna arrays, and a beamforming circuit configured to weight signals for the plurality of antenna arrays to coordinate the steerable antenna beams from a subset of the plurality of antenna arrays to form a combined antenna beam in a first steering direction.
