MOBILITY-AWARE ANTENNA BEAM TRACKING FOR MOVING COMMUNICATION DEVICES

Title:

MOBILITY-AWARE ANTENNA BEAM TRACKING FOR MOVING COMMUNICATION DEVICES

Document Type and Number:

WIPO Patent Application WO/2022/062829

Kind Code:

A1

Abstract:

Moving communication devices present challenges for conventional antenna beam sweeping techniques. According to embodiments of mobility-aware antenna beam tracking as disclosed herein signaling is communicatedbetween a User Equipment (UE) and a moving communication device in a wireless communication network. The signaling is indicative of a beam trajectory along which an antenna beam, that is associated with the moving communication device, is moving. The moving communication device itself is also moving, along a device trajectory that may or may not be the same as the beam trajectory. The antenna beam is used for subsequent directional communications between the UE and the moving communication device.
