Title:
METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING SECONDARY SYNCHRONIZATION SIGNAL IN WIRELESS ACCESS SYSTEM SUPPORTING NARROWBAND INTERNET OF THINGS
Document Type and Number:
WIPO Patent Application WO/2017/057986
Kind Code:
A9
Abstract:
The present invention provides a method and devices for transmitting and receiving a synchronization signal and a method for generating a synchronization signal in a wireless access system supporting narrowband Internet of Things (NB-IoT). A method for transmitting a narrowband secondary synchronization signal (N-SSS) by a base station in a wireless access system supporting narrowband Internet of Things (NB-IoT), according to an embodiment of the present invention, can comprise the steps of: generating a first sequence having a size M so as to generate an N-SSS; generating a second sequence having a size M so as to generate an N-SSS; generating an N-SSS by means of the first sequence and second sequence; and transmitting the N-SSS by means of n OFDM symbols. The size of a bandwidth used in the wireless access system supporting NB-IoT is the size of one physical resource block (PRB), and one PRB can comprise twelve subcarriers in a frequency domain.
