Title:
METHOD AND APPARATUS FOR TRANSMISSION OF DOWNLINK SIGNAL FOR INITIAL ACCESS IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/221468
Kind Code:
A1
Abstract:
The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). According to embodiments of the disclosure, a synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH) may be transmitted using first and second beams. One or more symbols adjoining the first and second synchronization signals may be configured to accommodate a beam switching time.
