= -6dB, 
= -6dB, σ = 3dBThe UE capability for 1024QAM is signalled per band or per band combination, hence the SDR tests with the mixed modulation orders and the mixed receiver antenna numbers across CC-s are specified.
For UE not supporting CA and supporting 1024QAM, the TB success rate shall be higher than 85% when PDSCH is scheduled with FRC in Table 8.7.16-4 according the UE capability. The maximum supported channel bandwidth and MIMO layer are configured during the test.
For UE supporting CA and supporting 1024QAM at least on one CC for a supported CA configuration, the SDR requirements are specified as follows:
– If UE is capable of supporting 256QAM, the TB success rate shall be higher than 85% on each CC when PDSCH-s are scheduled with FRC-s in Table 8.7.16-3 for the transmission with 256QAM and Table 8.7.16-4 for the transmission with 1024QAM according to the reported capability of supported modulation order for the determined CA configuration.
– If UE is not capable of supporting 256QAM, the TB success rate shall be higher than 85% on each CC when PDSCH-s are scheduled with FRC-s in Table 8.7.16-2 for the transmission with 64QAM and Table 8.7.16-4 for the transmission with 1024QAM according to the reported capability of supported modulation order for the determined CA configuration.
For UE supporting 1024 QAM, the SDR requirement with 64QAM and 256QAM only is not applicable.
The CA configuration or band for single carrier, bandwidth combination or bandwidth for single carrier, modulation order on each CC and MIMO layer on each CC are determined by the following procedure.
– Among all the supported CA configurations which support 1024QAM at least on one CC, select one set of {CA configuration or a band, bandwidth combination or bandwidth, modulation order on each CC, MIMO layer on each CC}, which leads to the largest equivalent aggregated bandwidth. The equivalent aggregated bandwidth is defined as
Where N is the number of CCs, 
represents the MIMO layer, 
represents the bandwidths on each CC, [
is the scaling factor according to the supported modulation order on each CC, where Mi = 0.75 is used if the maximum modulation order of CC i is 64QAM, Mi = 1 is used if the maximum modulation order of CC i is 256QAM, and Mi = 1.25 is used if the maximum modulation order of CC i is 1024QAM.]
– When there are multiple sets of {CA configuration or a band, bandwidth combination or bandwidth, modulation order on each CC, MIMO layer on each CC} which can reach the same equivalent aggregated bandwidth, select one among the sets with the largest number of CCs supporting 1024QAM.
– When there are multiple sets of {CA configuration or a band, bandwidth combination or bandwidth, modulation order on each CC, MIMO layer on each CC} which can reach the same equivalent aggregated bandwidth with the same number of CCs supporting 1024QAM, select one among the sets with the largest number of CCs supporting 4 layer.
– The procedure applies also for the single carrier operating band instead of CA configuration, and bandwidth instead of bandwidth combination.
The TB success rate for single carrier or on each CC for CA is defined as 100%*NDL_correct_rx/ (NDL_newtx + NDL_retx), where NDL_newtx is the number of newly transmitted DL transport blocks, NDL_retx is the number of retransmitted DL transport blocks, and NDL_correct_rx is the number of correctly received DL transport blocks. The TB success rate shall be sustained during at least 300 frames.
