Abstract: In LTE (Long Term Evolution) systems, the PRB (Physical Resource Block ) usage ratio is considered importantly to manage the QoS (Quality of Service) of LTE traffic. As the PRB usage ratio increases, the resource may not be allocated in a timely and reliable manner to the users of the cell.
Read moreHow many Re is one PRB?
The RE is the smallest physical channel unit, each uniquely identifiable by its subcarrier index k and symbol index l within the PRB. A PRB spans 12 subcarriers over 7 OFDM symbols and in total 12 × 7 = 84 REs .

Physical Resource Block . A E-UTRA PRB (Physical Resource Block) is defined as consisting of 12 consecutive subcarriers for one slot (0.5 ms). A PRB is the smallest element of resource allocation assigned by the eNB scheduler.
Read moreWhat is resource block group?
First it divides resource blocks into multiples of groups. This resource block group is RBG(Resource Block Group) called. The number of resource block in each group varies depending on the system band width. It means RBG size gets different depending on the system bandwidth. … Resource Allocation Type.

Read moreWhat is RBG LTE?
In Resource Allocation Type 0, Resource Block assignment information includes a bitmap indicating a set of Resource Block Groups (RBGs) to the scheduled UE. An RBG is a set of consecutive PRBs .
Read moreWhat is RB and PRB in 5G?
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.
