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 moreWhat is LTE transport block?
The data from the upper layer (or MAC) given to the physical layer in LTE system is basically referred as transport block. For single antenna transmission mode viz. SISO , there will be 1 transport block which will be generated for each TTI(Transmission Time Interval).
Read moreWhat is common resource block?
Common Resource Blocks (CRBs) Common resource blocks are numbered from 0 and upwards in the frequency domain for each subcarrier spacing configuration ‘µ’ . The CRBs associated with each and every SCS are aligned at Point A i.e., the center of subcarrier#0 of CRB#0 for each subcarrier spacing coincides with Point A.
Read moreWhat is the resource block in LTE?
A resource block (RB ) is the smallest unit of resources that can be allocated to a user . The resource block is 180 kHz. … The 89600 VSA LTE demodulator currently only supports resource blocks that are 12 subcarriers wide. Frequency units can be expressed in number of subcarriers or resource blocks.
Read moreHow are resource blocks allocated in LTE?
In LTE, radio resources are divided into time and frequency resource elements. Resource elements in time axis are divided into number of OFDM symbols and in frequency axis are divided into number of sub-carriers . Resource element (RE) is a smallest resource unit, which occupies a single sub-carrier and an OFDM symbol.
Read moreHow are resource blocks calculated?
For 50 Mbls one has to assign x blocks= (50/100.8)x total no. of resource blocks(100)= one has to assign 50 resource blocks, and in case of 60 Mbls the number of assigned RBs= (60/100.8) 100=60. In one second the transmitted bits will be 50Mbits and 60 Mbits respectively.
