TFRI Transport Format and Resource Indicator
This includes information about the dynamic part of the HS-DSCH transport format, including transport block set size and modulation scheme. The TFRI also includes information about the set of channelization codes onto which HS-DSCH is mapped in the corresponding HS-DSCH transmission. The number of bits defined are: - Channelization-code set -7 bits. - Modulation scheme - 1 bit. - Transport-block size - 6 bits.
