Signal Studio for LTE/LTE-Advanced FDD currently supports only FDD with frame structure type 1.
Figure 1 illustrates an uplink resource block made up of resource elements. Each resource element corresponds to an SC-FDMA symbol. An index pair (k,l) defines a resource element, where k represents the resource element position in the frequency domain and l represents the resource element position in the time domain.
An uplink resource block is defined as 
consecutive SC-FDMA symbols in the time domain,
and 
consecutive subcarriers in the frequency domain. This corresponds
to one slot in the time domain and 180 kHz (12 subcarriers x 15 kHz per
subcarrier) in the frequency domain. The number of SC-FDMA symbols in
a slot () depends on the cyclic prefix as shown in the table below.
Refer to the 3GPPTS 36.211 document for more information about resource blocks.
