SSB transmission for improving low SINR across network
Disclosed is a method of transmitting Synchronization Signal Blocks (SSBs) in a Fifth-Generation (5G) New Radio (NR) cellular telecommunication Radio Access Network (RAN). The method is performed by a Radio Unit (RU) device and includes: transmitting first symbols from a first antenna in a first sector, two or more of the first symbols including a first SSB; transmitting second symbols from a second antenna in a second sector, two or more of the second symbols including a second SSB; and transmitting third symbols from a third antenna in a third sector, two or more of the third symbols including a third SSB. The transmitting is performed during a first time slot and a second time slot. The symbols including the first SSB, the symbols including the second SSB, and the symbols including the third SSB are transmitted during different time periods.
