A 5G
wireless communication
system to transmit a beam ID or part of a beam ID by joint design of a secondary synchronization sequence (
SSS) and Physical Broadcast Channel (PBCH). In 5G during the initial access procedure a terminal will try to obtain fundamental
system information / identifiers which are required for future
signal transmission / reception activities. Due to the extensive usage of
beamforming techniques in 5G, besides identifying a
cell ID and obtaining time / frequency synchronization, the terminal may identify a beam ID during the initial access procedure. Therefore, a beam ID is transmitted as part of synchronization signals (SS) broadcast by a gNB, more particularly as part of
SSS or as part of PBCH. The synchronization signals may be transmitted as a set of SS blocks, each having an index, which may be a
time index, for facilitating identification.
