Resource Element(RE) : The smallest unit made up of 1 symbol x 1 subcarrier. RB (Resource Block) : I think everybody would know what this is. This is a unit of 84 resource elements which is 12 subcarrier by 7 symbols (This is with normal Cylic Prefix which is used in most of the LTE deployment.

5G NR retains the concept of 10 millisecond frame divided into 10 one-millisecond subframes.
Read moreWhat is the channel bandwidth of 5G?
In comparison, 5G NR maximum carrier bandwidth is up to 100 MHz in frequency range 1 (FR1: 450 MHz to 6 GHz), or up to 400 MHz in frequency range 2 (FR2: 24.25 GHz to 52.6 GHz) that can be aggregated with a maximum bandwidth of 800 MHz.
Read moreWhat is a carrier bandwidth?
According to 38.211 4.4. 5, A carrier bandwidth part is defined as follows : Carrier Bandwidth Part is a contiguous set of physical resource blocks,selected from a contiguous subset of the common resource blocks for a given numerology(u) on a given carrier .
Read moreWhat is CRB 5G?
CRB refer to common resource block , i.e. BW of 5G divided into multiple CRB used for BWP. PRB refer to block assigned to user by scheduler. In 5G we have VRB to PRB mapping which depends on Downlink resource allocation type, it can be interleaved or non inter leaved.
Read moreWhat is BWP in 5G?
One of the basic concepts in 5G NR is bandwidth part (BWP), which is, at a high level, a set of contiguous resource blocks configured inside a channel bandwidth .
Read moreHow many bandwidth parts can be active anytime for each UE?
A UE can be configured with up to four bandwidth parts in the downlink, with a single downlink bandwidth part being active at one time.
