Cell search is the procedure by which a UE acquires time and frequency synchronization with a cell and decode the Cell ID of that cell . In 5G NR, Cell search concept is similar to what it is in LTE in terms of decoding Primary Sync Signal (PSS) and Secondary Sync Signal (SSS) to the Physical Cell ID (PCI).28 Tem 2019

Channel raster is the distance between neighboring channels in a frequency band .18 May 2018
Read moreWhat is sync raster?
The synchronization raster indicates the frequency positions of the synchronization block that can be used by the UE for system acquisition when explicit signaling of the synchronization block position is not present .
Read moreWhat is LTE Earfcn?
EARFCN stands for E-UTRA Absolute Radio Frequency Channel Number .In LTE, the carrier frequency in the uplink and downlink is designated by EARFCN, which ranges between 0-65535. EARFCN uniquely identify the LTE band and carrier frequency.

A resource block (RB ) is the smallest unit of resources that can be allocated to a user . The resource block is 180 kHz. wide in frequency and 1 slot long in time.
