In 5G, One NR Resource Block (RB) contains 12 sub-carriers in frequency domain similar to LTE . In LTE resource block bandwidth is fixed to 180 KHz but in NR it is not fixed and depend on sub-carrier spacing.
Read moreWhat is resource allocation type in 5G?
Resource Allocation Type specifies the way in which the scheduler allocate resource blocks for each transmission . Just in terms of flexibility, the way to give the maximum flexibility of resource block allocation would be to use a string of a bit map (bit stream), each bit of which represent each resource block.

– A resource grid is characterized by one subframe in time domain and full carrier bandwidth in the frequency domain . … – There are a set of resource grids per transmission direction (uplink or downlink).

Read moreWhat is PRB in 5G NR?
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 5G resource grid?
It is the smallest unit of the resource grid made up of one subcarrier in frequency domain and one OFDM symbol in time domain. … There is one resource grid for a given antenna port p , subcarrier spacing configuration u, and transmission direction (downlink or uplink).
Read moreWhat is RRC setup in 5G?
The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station . This protocol is specified by 3GPP in TS 25.331 for UMTS, in TS 36.331 for LTE and in TS 38.331 for 5G New Radio.
