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.

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.

In multi-user MIMO (MU-MIMO), which is shown in the bottom right quadrant of Figure 1, the AAS simultaneously sends different layers in separate beams to different users using the same time and frequency resource , thereby increasing the network capacity.
