ork and Radio Access Technology 4.6.13.1 Blind Transport Format Detection In the absence of TFCI explicit blind detection or guided detection takes place on all TrCHs within the CCTrCH that have more than one transport format. However accord- ing to [10], the UE will support blind transport format detection only if all of the following conditions apply: 1. the number of CCTrCH bits received per radio frame < 600; 2. the number of transport format combinations of the CCTrCH 64; 3. the CCTrCH under detection use fixed positions of the transport channels; 4. all explicitly detected TrCHs use convolutional coding; 5. we append CRC to all transport blocks on all explicitly detected TrCHs; 6. the number of explicitly detected TrCHs < 3; 7. for all explicitly detected TrCHs i, the number of code blocks in one TTI (Cj) does not exceed 1; 8. the sum of the transport format set sizes of all explicitly detected TrCHs, 16.; 9. there is at least one usable TrCH in guiding a transport channel for all transport channels using guided detection. See examples in [10]. 4.6.13.2 Transport Format Detection Based on TFCI When a TFCI exists, TFCI based detection applies to all TrCHs within the CCTrCH, where the TFCI informs the receiver about the transport format combination of the CCTrCHs. Right after the TFCI detection we know the transport format combination as well as the transport formats of the individual transport channels. TFCI coding. As illustrated in Figure 4.52, we encode TFCI bits using a (32,10) sub- code of the second order Reed-Muller code.

If the TFCI < 10 bits, we pad it with zeros to 10 bits, by setting the most significant bits to zero. The length of the TFCI code word = 32 bits. The code words of the (32,10) sub-code of second order Reed-Muller code has a linear combination of 10 basis sequences. If we define the TFCI information bits as ao,a1,a2,a3,a4,a5,a6,a7,ag,ag, where ao = LSB and a9 = MSB,
