Abstract: Devices for and methods of synchronous beam refinement using a beam refinement reference signal (BRRS) are generally described. In one example embodiment, a UE receives BRRS information indicating switching of a Tx beam. The UE then uses this information to switch an associated Rx beam. In some embodiments, timing information is used to match the switching times. In some embodiments. DCI and CSI-RS operations are used to determine switching for the synchronous beam refinement.

Abstract: A user equipment (UE) may receive, from a base station (BS) configured to support activation of a secondary cell (SCell), a request to provide a measurement report. In response to the request, the UE may perform one or more measurements on the SCell using one or more reference signals (RSs). Additionally or alternatively, the UE may generate the measurement report based on the one or more measurements and further transmit the measurement report to the BS. In some embodiments, the UE may further determine a pathloss estimation based on the one or more measurements.

Abstract: A network may transmit either beam deployment information or beam number information to a user equipment (UE) carried on a train and configured for operation in the millimeter wave band. The deployment information may include deployment related distance parameters or azimuth angle spread parameters. The beam number information may indicate a number of network beams associated with a current cell. The UE may determine a number of UE receive beams based on deployment information or the network-indicated number of network beams. The UE may transmit feedback to the network, indicating the number of UE receive beams. Alternatively, the network may send a configuration message indicating a first number of UE receive beams to the UE, which the UE may treat as an upper bound or lower bound in its determination of a desired number of UE receive beams. The UE may transmit the desired number to the network.

Abstract: This disclosure relates to techniques for a wireless device to initiate channel occupancy in unlicensed spectrum in a wireless communication system. The wireless device may establish a wireless link with a cellular base station. The wireless device may determine to perform an uplink transmission to the cellular base station on an unlicensed frequency channel. The wireless device may determine whether the cellular base station has channel occupancy of the unlicensed frequency channel. The wireless device may determine whether to initiate channel occupancy of the unlicensed frequency channel. The decision whether to initiate channel occupancy may be based at least in part on whether the cellular base station has channel occupancy of the unlicensed frequency channel.
