Techniques for NR cell/beam identification
Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for cell identification (ID) and beam ID detections in new radio (NR). The detections comprise NR primary synchronization signal (PSS)/secondary synchronization signal (SSS) detection, PBCH DMRS detection, SS reference signal received power (RSRP) measurement, and slot/SS burst boundary timing acquiring. Various embodiments describe how to detect a cell ID and a beam ID in millimeter wave (mmWave) operation. Other embodiments describe further details regarding how to detect NR cell and beam ID during intra-frequency measurements.
