NOTE 1: If more than one Code Block is present, an additional CRC sequence of L = 24 Bits is attached to each Code Block (otherwise L = 0 Bit)

NOTE 2: Parameters related to NPUSCH format 1 scheduling are defined in Table A.2.4-2.

NOTE 3: NPDCCH is not transmitted in the subframes used for transmission of SI messages.

NOTE 4: SI messages transmission should be prioritized over NPDCCH transmission in case of collision. NPDCCH transmission is postponed until the next NB-IoT downlink subframe in case NPDCCH transmission occurs in a non NB-IoT downlink subframe, where an NB-IoT downlink subframe is a subframe that does not contain NPSS/NSSS/NPBCH/SIB1-NB transmission.

NOTE 5: Number of repetition N_Rep as defined in table 16.5.1.1-3 in TS 36.213 [6].
