Title
(EN) MOBILITY FOR RADIO DEVICES USING BEAMFORMING AND SELECTION
(ZH) 使用波束成形和选择的无线电设备的移动性
Abstract
(EN)
Multiple mobility sets are maintained for nodes of radio networks. The sets comprise information such as: transmit and receive point identities; cell identities; beam identities; frequency channels; channel bandwidth; and black lists. The sets may be defined at different levels, such as network and physical (PHY) level. A network mobility set, e.g., a new-radio (NR) mobility set may, be determinedby the gNB, the cell, the UE, or another device. Multiple radio access network nodes and UEs may exchange mobility set information to achieve a distributed mobility solution. A UE may monitor its orientation relative to a TRP, e.g., via use of an onboard MEMS gyroscope, and alter its beamforming parameters in response to changes in orientation and/or changes in TRP connection strength. Cell selection and reselection for beam based networks may use Single Frequency Network (SFN) broadcast of initial access signals without beam sweeping.

为无线电网络的节点维护多个移动性集合。这些集合包括诸如以下信息:发送和接收点身份;小区身份;波束身份;频率信道;信道带宽;以及黑名单。可以在不同级别定义集合,诸如网络和物理(PHY)级别。网络移动性集合,例如新无线电(NR)移动性集合,可以由gNB、小区、UE或另一个设备确定。多个无线电接入网络节点和UE可以交换移动性集合信息以实现分布式移动性解决方案。UE可以例如经由使用板载MEMS陀螺仪来监视其相对于TRP的朝向,并且响应于朝向的改变和/或TRP连接强度的改变而改变其波束成形参数。用于基于波束的网络的小区选择和重选可以使用初始接入信号的单频网络(SFN)广播而不进行波束扫掠。
