AI Technical Summary

Technical Problem

In sideline communication, the sending node cannot perform initial beam pairing because the receiving node has multiple synchronous reference sources, resulting in a synchronization priority rule that needs to be redesigned and optimized.

Method used

By receiving one or more sideline synchronization signal blocks, the synchronization reference is selected according to the first priority group order, ensuring initial beam pairing is performed before the sideline unicast link is established. The order of the priority group is related to initial beam pairing, side-line unicast link establishment, beam management, and identification and resource occupation of side-line synchronization signal blocks.

Benefits of technology

Effective initial beam pairing is realized, synchronization priority rules are optimized, synchronization priority of sending nodes is increased, resource waste is reduced, and the scope of communication links is expanded.

Abstract

The present application provides a method and apparatus in a node for wireless communication to implement initial beam pairing based on a sidewalk synchronization signal block. The method includes: receiving one or more sidewalk synchronization signal blocks, wherein the one or more sidewalk synchronization signal blocks include a first sidewalk synchronization signal block, wherein the first sidewalk synchronization signal block is configured for a first operation, and / or the first sidewalk synchronization signal block carries a first type of identifier, and / or the first sidewalk synchronization signal block occupies a first type of resource; selecting a synchronization reference according to a first priority group order; wherein the first operation includes at least one of initial beam pairing, sidewalk unicast link establishment, and sidewalk beam management; the first priority group order is related to the first operation and / or the sidewalk synchronization signal block carrying the first type of identifier and / or the sidewalk synchronization signal block occupying the first type of resource.
