Title:
BEAM MANAGEMENT METHOD, RELAY TRANSCEIVING NODE, TERMINAL AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2019/206168
Kind Code:
A1
Abstract:
Disclosed are a beam management method, a relay transceiving node, a terminal and a base station. The method comprises: a relay transceiving node determining a first resource group and a second resource group, and sending a beam in a first beam group according to a correlation between a resource unit comprised in the first resource group and the beam in the first beam group; and sending a beam in a second beam group according to a correlation between a resource unit comprised in the second resource group and the beam in the second beam group, wherein when resource units comprised in the first resource group and resource units comprised in the second resource group comprise the same resource unit, a beam sent on the same resource unit is a shared beam for an access link and a backhaul link. Using the same resource unit to send a shared beam of an access link and a backhaul link is beneficial to reduce resource overheads of managing the beam, and reduce the total time delay of a beam management process.
