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 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 moreWhat is resource block allocation?
A resource block (RB) is a minimum resource allocation unit to any single user . One resource block occupies 12 sub-carriers and 6/7 OFDM symbols. Therefore, a resource block can have total 72/84 resource elements. The technology supports flexible bandwidths such as 1.4MHz, 3MHz, 5MHZ, 10MHz, 15MHz and 20MHz.

FR2. 24250 MHz – 52600 MHz .
Read moreWhat is the maximum Tx bandwidth configuration?
Maximum transmission bandwidth configuration 2-1 . Note: SCS of 60kHz can be used for both FR1 and FR2. … FR1 may use channel bandwidth of up to 50MHz when using 15kHz subcarrier spacing, and up to 100MHz when using 30 or 60kHz subcarrier spacings.
