RBG is the resource block group size when PDSCH has resource allocation type 0 . Type 0 resource allocation has distributed PRB allocation for UE. This distribution is based on the PRB group. PRB group size depends on BW.
Read moreWhat are resource blocks?
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.
Read moreWhat are resource blocks 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.24 Nis 2019
Read moreHow are resource blocks allocated in 5G?
In 5G NR, similar to 4G the resource allocation is done in Time domain and frequency domain . Time domain resource allocation defines which symbols are allocated to UE and frequency domain allocation defines which RBs are allocated to the UE.
Read moreWhat is frequency raster in LTE?
The center frequency of an LTE carrier is assumed to be on a 100 kHz channel raster (known also as carrier grid) in order to allow the LTE UEs to search a limited number of carrier frequencies in the frequency bands they support and synchronize within a reasonable amount of time after being activated.18 May 2018
Read moreWhat is sync raster in 5G?
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 channel raster?
The channel raster for LTE is 100 kHz for all bands and the center frequency must therefore be a whole number multiple of 100 kHz.
