Title:
METHOD AND APPARATUS FOR MEASURING DOWNLINK SYNCHRONIZATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/213375
Kind Code:
A1
Abstract:
Provided are a method and an apparatus for obtaining a downlink synchronization in a wireless communication system. A proposed wireless communication system has an environment in which a resource position of a downlink synchronization signal is changed as multi-numerology is applied thereto. Specifically, a terminal transmits a preamble for requesting a synchronization signal transmission resource to a base station. The terminal receives a response signal to the preamble from the base station. Here, the terminal does not have linkage to the base station, and is downlink synchronized with the base station. The response signal includes position information of a synchronization signal transmission resource of a neighboring base station.
