(EN) Design for initial access in new radio unlicensed spectrum
(ZH) 新无线电未授权频谱的初始接入设计
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 ormultiple 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.
(ZH) 本发明描述了新无线电未授权频谱中用于初始接入设计的技术和示例。装置从无线网络的基站接收一个或多个同步信号和物理广播信道块(SS/PBCH块),其索引由取决于对话前监听(LBT)结果的循环围绕顺序表示。该装置还在该基站分配的随机接入信道(RACH)资源上发送随机接入请求。
