efficiency over 5G NR. The 12 Panel S-MIMO performance
meets/exceeds this target.

Coverage: The Link Budget Table illustrates the coverage
in an Urban Macro scenario, where a 384-antenna element
panel is utilized. The DL coverage is shown in Figures 11
(Urban Macro) and 12 (Rural Macro) for 7 GHz frequency
band (with 250MHz allocated bandwidth), indicating the
feasibility of achieving coverage comparable to midband
using S-MIMO concepts. However, it is important to note
that UL coverage faces limitations due to the constrained
availability of antennas and power at the UE as shown in
Figures 13 and 14 for Urban Macro and Rural Macro
respectively.
Peak Data Rate: The value of this parameter relies on the
system's employed bandwidth. In the upper midband, where
1GHz is assumed to be available in a region with four
operators, a minimum bandwidth of 250 MHz can be Figure 11 – DL Link Budget for indoor UEs (UMa)
allocated to each operator. This increase in bandwidth alone
leads to a remarkable enhancement of at least 2.5 times in
average, cell-edge, and peak data rates. The comprehensive
analysis and ensuing results conclusively demonstrate that
the amalgamation of OTFDM and S-MIMO technologies
exhibits the potential to fulfill the targeted requirements set
by ITU.
