Title:
SYSTEM AND METHOD FOR BEAMFORMED BROADCAST AND SYNCHRONIZATION SIGNALS IN MASSIVE MULTIPLE INPUT MULTIPLE OUTPUT COMMUNICATIONS SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2018/019096
Kind Code:
A1
Abstract:
A method for transmitting beamformed signals includes beamforming a synchronization signal in accordance with a first set of spatially separated transmission beams, thereby producing first beamformed synchronization signals, transmitting the first beamformed synchronization signals, determining if a first synchronization cycle is complete, and when the first synchronization cycle is not complete, rotating the first set of spatially separated transmission beams, and repeating the beamforming, the transmitting, and the determining until the first synchronization cycle is complete.
