UCI and data multiplexing are transmitted on Pusch (Part 4) --small block lengths

Block length encoding

There are three kinds of codes with small and fast coding length , The first is the length 1, The second is the length 2, The third is the length 3~11. There are different ways to deal with .

1. The length is 1 perhaps 2 The coding

x,y It's a placeholder , When scrambling , Placeholder and normal data processing are different .
This is right with Qm And the corresponding relationship between modulation mode

 % Encode, with placeholder bits
    x = -1;
    y = -2;
    if length(uciBits)==1 % A=1
        if Qm==1
            out = uciBits;
        else
            out = [uciBits; y; repmat(x,Qm-2,1)];
        end
    else % A=2
        c2 = xor(uciBits(1),uciBits(2));
        if Qm==1
            out = [uciBits; c2];
        else
            ib = reshape(repmat([uciBits; c2],2,1),2,3);
            xb = repmat(x,Qm-2,3);
            out = reshape([ib;xb],[],1);
        end
    end

2. The length is 3~11 Use RM code
