METHOD AND SYSTEM FOR SENSOR-BASED BEAM MANAGEMENT BY USER EQUIPMENT

Title:

METHOD AND SYSTEM FOR SENSOR-BASED BEAM MANAGEMENT BY USER EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2019/194659

Kind Code:

A1

Abstract:

A method and system are provided for sensor-based beam management by user equipment (UE). The method includes obtaining, by the UE, a reference beam pair and a first set of neighbor beam pairs in a first reception direction for connecting with a network; determining, by the UE, a change in the first reception direction, based on sensor data; identifying, by the UE, a second set of neighbor beam pairs in the changed first reception direction; measuring, by the UE, a plurality of beam parameters for neighbor beam pairs in the second set of neighbor beam pairs; determining, by the UE, an optimal beam pair from the identified second set of neighbor beam pairs based on the plurality of measured beam parameters; and configuring, by the UE, an optimal beam pair for connecting with the network.
