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.
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 resource block and resource element?
A Resource Element is one 15 kHz subcarrier by one symbol. Resource Elements aggregate into Resource Blocks . A Resource Block has dimensions of subcarriers by symbols. Twelve consecutive subcarriers in the frequency domain and six or seven symbols in the time domain form each Resource Block.
Read moreWhat are physical resource blocks?
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 moreHow many slots are present in 5G subframe?
In this configuration, a subframe has 16 slots in it, it means a radio frame contains 160 slots in it. The number of OFDM symbols within a slot is 14.
Read moreWhat is resource grid in 5G?
– 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).
