– Table 7.1.7.2.1-1 when the transport block is mapped to one spatial layer,

– The union of Table 7.1.7.2.1-1 and Table 7.1.7.2.5-1 when the transport block is mapped to four spatial layers.

If the scaled TBS is closest to two valid transport block sizes, it is rounded to the larger transport block size.

NOTE 1: In the rounding procedure, and for a given serving cell:

– For UEs configured with neither altCQI-Table1024QAM-STTI nor altCQI-TableSTTI, the UE shall only include in the rounding procedure the TBS entries present in Table 7.1.7.2.1-1 with , and the entries in 7.1.7.2.2-1, 7.1.7.2.4-1, 7.1.7.2.5-1 for which the TBS_L1 is present in Table 7.1.7.2.1-1 with .

The UE may skip decoding a transport block in an initial transmission if the effective channel code rate is higher than 0.932, where the effective channel code rate is defined as the number of downlink information bits (including CRC bits) divided by the number of physical channel bits on PDSCH. If the UE skips decoding, the physical layer indicates to higher layer that the transport block is not successfully decoded. For the special subframe configurations 0 and 5 with normal downlink CP or configurations 0 and 4 with extended downlink CP in frame structure type 2, or for subframes with the same duration as the DwPTS duration of the special subframe configuration 0 and 5 in frame structure type 3, with the special subframe configurations shown in Table 4.2-1 of [3], or for the special subframe configuration 10 configured by the higher layer signalling ssp10-CRS-LessDwPTS, a non-BL/CE UE shall assume there is no PDSCH transmission in DwPTS of the special subframe.

7.1.7.2.2 Transport blocks mapped to two-layer spatial multiplexing

For, the TBS is given by the (,) entry of Table 7.1.7.2.1-1.

For, a baseline TBS_L1 is taken from the (,) entry of Table 7.1.7.2.1-1, which is then translated into TBS_L2 using the mapping rule shown in Table 7.1.7.2.2-1. The TBS is given by TBS_L2.

7.1.7.2.5 Transport blocks mapped to four-layer spatial multiplexing

For , the TBS is given by the (,) entry of Table 7.1.7.2.1-1.

For , a baseline TBS_L1 is taken from the (,) entry of Table 7.1.7.2.1-1, which is then translated into TBS_L4 using the mapping rule shown in Table 7.1.7.2.5-1. The TBS is given by TBS_L4.

7.1.7.3 Redundancy Version determination for Format 1C

If the DCI Format 1C CRC is scrambled by P-RNTI or RA-RNTI, then

– the UE shall set the Redundancy Version to 0

Else if the DCI Format 1C CRC is scrambled by SI-RNTI, then

– the UE shall set the Redundancy Version as defined in [8].
