8.6 Modulation order, redundancy version and transport block size determination
36.2133GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Physical layer proceduresRelease 17TS
To determine the modulation order, redundancy version and transport block size for the physical uplink shared channel, the UE shall first
– for a cell that is
– a LAA SCell or,
– configured with higher layer parameter shortProcessingTime and the PDCCH with CRC scrambled by C-RNTI corresponding to the PUSCH is in the UE-specific search space, or
– configured with higher layer parameter shortTTI and the associated DCI is of format 7-0A/7-0B,
– read the "modulation and coding scheme" field () and "redundancy version" field (),
– otherwise
– if the UE is a non-BL/CE UE,
– read the "modulation and coding scheme and redundancy version" field ()
– elseif the UE is a BL/CE UE,
– for transmission using preconfigured uplink resources,
– read the higher layer parameter mcs-r16 in PUR-Config
– otherwise
– read the "modulation and coding scheme" field ()
and
– check the "CSI request" bit field, and
– compute the total number of allocated PRBs () based on the procedure defined in Clause 8.1, and
– compute the number of coded symbols for control information.
