METHOD FOR TRANSMITTING SYNCHRONIZATION SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2018/164414

Kind Code:

A1

Abstract:

The present invention discloses a method of transmitting an SSS (secondary synchronization signal), which is transmitted by a base station, in a wireless communication system. The method includes the steps of determining a first shift based on a first and a second cell identifiers for identifying a cell, and determining a second shift index based on the first cell identifier and transmitting the SSS using a first sequence which is generated based on the first shift index and a second sequence which is generated based on the second shift index. In this case, the first shift index can be determined as K times a value determined based on the first and second cell identifiers, where K is an integer equal to or greater than 3.
