% This function computes the uncoded rate per second for a coded rate. It
|
|
% basically caps the rate to the one given in the table below.
|
|
%
|
|
% The maximum uncoded throughput is derived as follows. Each DL subframe
|
|
% contains 3600 REs out of which 400 REs are used for pilots and 800 for
|
|
% the PDCCH, leaving 2400 REs for the DLSCH. Each UL subframe has 3600 RE,
|
|
% out of which 600 are used for pilots and 300 for the SRS, leving 2700 REs
|
|
% for the ULSCH. Assuming TDD frame configuration 3 (6 DL subframes, 3 UL
|
|
% subframes, 1 special subframe), this results in a maximum throughput of
|
|
%
|
|
% DL UL
|
|
% QPSK: 2.88 Mbps 1.62 Mbps
|
|
% 16QAM: 5.76 Mbps 3.24 Mbps

% 64QAM: 8.64 Mbps 4.86 Mbps
