Note 1: Note 2: 50 resource blocks are allocated in sub-frames 4,9 and 41 resource blocks (RB0–RB20 and RB30–RB49) are allocated in sub-frame 0 and the DwPTS portion of sub-frames 1,6. Note 3: The precoder in clause B.4.3 follows UE recommended PMI. Note 4: If the UE reports in an available uplink reporting instance at subrame SF#n based on PMI estimation at a downlink SF not later than SF#(n-4), this reported PMI cannot be applied at the eNB downlink before SF#(n+4). |

.For UE not supporting 256QAM, the TB success rate shall be higher than 85% when PDSCH are scheduled with FRC in Table 8.7.19-2 with the downlink physical channel setup according to Annex C.3.2.
For UE supporting 256QAM, the TB success rate shall be higher than 85% when PDSCH are scheduled with FRC in Table 8.7.19-3 with the downlink physical channel setup according to Annex C.3.2. For UE supporting 256QAM, the requirement with 64QAM is not applicable.
The TB success rate 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.

CA configuration, bandwidth combination and MIMO layer on each CC is determined by following procedure.
- Select the set(s) of {CA configuration, bandwidth combination, MIMO layer} among all the supported CA configurations that leads to the largest equivalent aggregated bandwidth which does not cause the transport block bits within a TTI to exceed the capability of the category of UE under test when the defined reference channel applies on each CC. The equivalent aggregated bandwidth is defined as
Where 
is the number of CCs, 
and 
are MIMO layer and bandwidth of CC 
. And 
for 
and 
for 
– The procedure applies also for single carrier using operating band instead of CA configuration, and bandwidth instead of bandwidth combination.
