9.3 Peak L1 throughput Peak L1 throughput values confirm Flexi System Module as compliant with 3GPP Release 8. Refer to the tables below for the maximum Transport Block Sizes, which can be set for 2x2MIMO (dual-stream transmission) with all available frequency resources.

3GPP Release 8 specifies QPSK, 16QAM and 64QAM for PUSCH. In RL30/RL25TD there is no support for 64QAM transmission however it is possible to extend MCS range for 16QAM from MCS index 20 to 24. Flexi Rel.2 and Rel.3 are fully capable of handling the largest possible Transport Blocks. It means that the HW architecture (processing power of DSP boards) does not limit peak data rates.

9.4 Supported cell range Maximum cell range is physically limited by supported RA preamble formats which are listed below. Table 67
