38、ave been obtained with a transmission time reduction method. The transmission gap can be contained in one or two consecutive radio frames. TGL: Transmission Gap Length is the number of consecutive empty slots that have been obtained with a transmission time reduction method. O STGLS 14. The CFNs of

40、mpty slots of the transmission gaps, and the transmission gap lengths can be calculated with the compressed mode parameters described in 5. TrCH number: The transport channel number identifies a TrCH in the context of L1. The L3 transport channel identity (TrCH ID) maps onto the L1 transport channel
41、 number. The mapping between the transport channel number and the TrCH ID is as follows: TrCH 1 corresponds to the TrCH with the lowest TrCH ID, TrCH 2 corresponds to the TrCH with the next lowest TrCH ID and so on. 3.2 Symbols For the purposes of the present document, the following symbols apply: /

The code blocks after segmentation are of the same
43、 size. The number of code blocks on TrCH i is denoted by Ci. If the number of bits input to the segmentation, Xi, is not a multiple of Ci, filler bits are added to the beginning of the first block. If turbo coding is selected andXi K, the dummy bits are padded such that y, = Oorl for k = K + 1, K +

These dummy bits are pruned away from the output of the rectangular matrix after intra-row and inter- row permutations. 4.2.3.2.3.2 Intra-row and inter-row permutations After the bits-input to the R X C rectangular matrix, the intra-row and inter-row permutations for the R X C recta
45、ngular matrix are performed stepwise by using the following algorithm with steps (1) - (6): (1) Select a primitive root v from table 2 in section 4.2.3.2.3.1, which is indicated on the right side of the prime number P. (2) Construct the base sequence (j), , p-21 for intra-row permutation as: s(j) =
46、(v x s(j - 1)modp , j = 1, 2,. . ., (p - 2), and s(0) = 1. (3) Assign qo = 1 to be the first prime integer in the sequence (qj)jEo,l,R-ll, and determine the prime integer qi in the sequence (qi)jEo,l ,., R-1) to be a least prime integer such that g.c.d(q, p - 1) = 1, qi 6, and qi qg . for each i = 1
