operational bandwidths in LTE scale are
1.4, 3, 5, 10, 15, and 20MHz, in paired and unpaired frequency bands. e LTE-A capabilities
enable the scaling of bandwidth beyond 20MHz, through the aggregation of the building-block
bandwidths of 1.4, 3, 5, 10, 15, and 20MHz. Arrangement of dierent bandwidths to allow ...
