Title:
METHOD FOR TRANSMITTING SYNCHRONIZATION SIGNAL USING CODEBOOK IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/034169
Kind Code:
A1
Abstract:
Disclosed are a synchronization signal transmission method and a base station, in which beamforming of synchronization signals is performed in the following manner: a codebook is configured by defining a plurality of third precoders by connecting basic precoders which respectively correspond to a plurality of antenna subarrays, the synchronization signals are repeatedly transmitted to a terminal by applying the third precoders selected from the codebook to a synchronization sequence across a plurality of time intervals, and the plurality of antenna subarrays are independently controlled by first precoders respectively corresponding thereto.
