    • An apparatus is configured to be employed within one or more nodes. The apparatus includes control circuitry and a transceiver. The control circuitry is configured identify a set of beam sector pairs using a sector level sweep (SLS), rank the set of beam sector pairs to generate a ranked set of beam sector pairs based on beam ranking criteria, and provide the ranked set of beam sector pairs to a second node. The transceiver is configured to communicate with the second node using a primary beam pair of the ranked set of beam sector pairs. The control circuitry of the nodes is further configured to detect blockage on the primary beam pair and to switch to alternative beam pairs according to the ranking exchanged between the communicating nodes upon blockage detection.
    • 一个装置被配置为在一个或多个节点内使用。 该设备包括控制电路和收发器。 控制电路被配置为使用扇区级扫描(SLS)来识别一组波束扇区对,对该组波束扇区对进行排序以基于波束排名标准来生成波束扇区对的排序集合,并且提供经排名的波束集合 扇区对到第二个节点。 收发器被配置为使用排序的波束扇区对的主波束对与第二节点通信。 节点的控制电路还被配置为检测主波束对上的阻塞并根据在阻塞检测时在通信节点之间交换的排名切换到替代波束对。

    • For cell acquisition a UE receives concurrently from a base station (BS), during a single time symbol, a cell ID via a plurality of electromagnetic beams that include data signals and spatial-frequency multiplexed orthogonal synchronization signals, the beams having different angles of arrival. The UE processes the beams to determine the identity of the beam that was received with maximum signal strength and the angle of arrival of the beam, and transmits the identity and the angle of arrival to the BS. For beam tracking the UE similarly receives a plurality of the same beams but including reference signals, each beam transmitted at the same power and received at different angles of arrival. The plurality of beams comprise a central beam and pairs of beams on either side of the central beam, the pairs respectively arranged at differing equal angles of arrival from the central beam. The UE processes the beams in parallel to track movement of the UE by determining the identity of the beam received with maximum signal strength and the angle of arrival of the beam, by using the central beam and the pairs of beams. The UE transmits the identity and the angle of arrival to the BS.
    • 为了小区捕获,UE经由包括数据信号和空间频率复用正交同步信号的多个电磁波束在单个时间符号期间从基站(BS)同时接收小区ID ,梁具有不同的到达角度。 UE处理波束以确定以最大信号强度和波束到达角度接收到的波束的身份,并将身份和到达角度发送到BS。 对于波束追踪,UE类似地接收多个相同的波束,但包括参考信号,每个波束以相同的功率发射并以不同的到达角度接收。 多个光束包括中心光束和在中心光束任一侧的光束对,这些光束对分别以不同的相同中心光束到达的角度布置。 UE通过使用中心波束和波束对确定以最大信号强度和波束到达角度接收的波束的身份,并行处理波束以跟踪UE的移动。 UE将身份和到达角度发送给BS。
