Title:

METHODS AND SYSTEMS FOR DETECTING PRIMARY SYNCHRONIZATION SIGNAL (PSS) IN A WIRELESS NETWORK

Document Type and Number:

WIPO Patent Application WO/2020/204608

Kind Code:

A1

Abstract:

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long-term evolution (LTE). Methods and devices are provided for detecting a synchronized primary synchronization signal (PSS) sequence in a wireless network is provided. A device receives a synchronization signal including a PSS sequence. The device determines a plurality of peak correlation values by correlating a plurality of predefined PSS sequences with time-shifted variants of the received synchronization signal. The device detects the synchronized PSS sequence from the plurality of predefined PSS sequences by analyzing the plurality of peak correlation values using at least one of probability detection values, a sliding window method, weight assignments, and a rewarding-based method.
