(EN) Design For Initial Access In New Radio Unlicensed Spectrum
Abrégé
(EN)

Techniques and examples of design for initial access in New Radio (NR) unlicensed spectrum (NR-U) are described. An apparatus receives from a base station of a wireless network which transmits one or multiple synchronization signal and PBCH blocks (SS/PBCH blocks) whose indices are indicated in a cyclic-wrapped order subject to a result of listen-before-talk (LBT) in NR-U. The apparatus also transmits a random access request on random access channel (RACH) resources allocated by the base station.
