4.2.4 Radio frame size equalisation

25.2123GPPMultiplexing and channel coding (FDD)Release 17TS

Radio frame size equalisation is padding the input bit sequence in order to ensure that the output can be segmented in F_i data segments of same size as described in subclause 4.2.7. Radio frame size equalisation is only performed in the UL.

The input bit sequence to the radio frame size equalisation is denoted by, where i is TrCH number and E_i the number of bits. The output bit sequence is denoted by, where T_i is the number of bits. The output bit sequence is derived as follows:

– t_ik = c_ik, for k = 1… E_i; and

– t_ik = {0, 1} for k= E_i +1… T_i, if E_i < T_i;

where

– T_i = F_i * N_i; and

– is the number of bits per segment after size equalisation.
