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 NRep as defined in table 16.5.1.1-3 in TS 36.213 [6]. |

Following NOTEs are included in TS 36.521-1 as an addition to TS 36.101, to define examples of UL scheduling patterns based on Table A.2.4-1 and Table A.2.4-2. Overall period of UL scheduling pattern corresponds with Si-periodicity and it consists of two different patterns with dependencies on SI transmission.
– One pattern applies for period containing SI messages transmission. This pattern has a period with same duration as SI windows length (time period where SI messages are transmitted).
– Another pattern for period where there is no transmission of SI messages. This pattern is repeated during SI periodicity.
Figure A.2.4-1: NPDCCH scheduling based on SI transmission
NOTE 1: For 3.75kHz, 1 tone, and π/2 BPSK modulation. NPDCCH transmission is scheduled at the 18th subframe (starting from the 0th subframe) every 80ms and its corresponding NPUSCH format 1 is scheduled 9 subframes after NPDCCH transmission. NPUSCH format 1 transmission has a duration of 64 consecutive ms. This pattern applies for both periods containing and not containing SI messages transmission.
NOTE 2: For 3.75kHz, 1 tone, and π/4 QPSK modulation. NPDCCH transmissions are scheduled at the 18th, 66th and 114th subframe (starting from the 0th subframe) every 160ms for periods containing SI messages transmission and at the 2nd, 51th, 98th, 146th and 194th subframe (starting from the 0th subframe) every 240ms for periods where there is no transmission of SI messages. The corresponding NPUSCH format 1 are scheduled 9 subframes after each NPDCCH transmission. NPUSCH format 1 transmission has a duration of 32 consecutive ms.
NOTE 3: For 15kHz, 1 tone, and π/2 BPSK modulation. NPDCCH transmissions are scheduled at the 18th, 51th, 98th and 131th subframe (starting from the 0th subframe) every 160ms for periods containing SI messages transmission and at the 2nd, 34th, 66th, 98th and 131th subframe (starting from the 0th subframe) every 160ms for periods where there is no transmission of SI messages. The corresponding NPUSCH format 1 are scheduled 9 subframes after each NPDCCH transmission. NPUSCH format 1 transmission has a duration of 16 consecutive ms.
NOTE 4: For 15kHz, 1 tone, and π/4 QPSK modulation. NPDCCH transmissions are scheduled at the 18th, 42th, 66th, 98th, 122th and 146th subframe (starting from the 0th subframe) every 160ms for periods containing SI messages transmission and at the 11th, 34th, 58th, 82th and 106th subframe (starting from the 0th subframe) every 120ms for periods where there is no transmission of SI messages. The corresponding NPUSCH format 1 are scheduled 9 subframes after each NPDCCH transmission. NPUSCH format 1 transmission has a duration of 8 consecutive ms.
NOTE 5: For 15kHz, 3 tones, and QPSK modulation. NPDCCH transmissions are scheduled at the 18th, 34th, 51th, 74th, 98th, 114th, 131th and 154th subframe (starting from the 0th subframe) every 160ms for periods containing SI messages transmission and at the 11th and 34th subframe (starting from the 0th subframe) every 40ms for periods where there is no transmission of SI messages. The corresponding NPUSCH format 1 are scheduled 9 subframes after each NPDCCH transmission. NPUSCH format 1 transmission has a duration of 4 consecutive ms.
NOTE 6: For 15kHz, 6 tones, and QPSK modulation. NPDCCH transmissions are scheduled at the 18th, 34th, 51th, 66th, 98th, 114th, 131th and 146th subframe (starting from the 0th subframe) every 160ms for periods containing SI messages transmission and at the 2nd, 18th, 34th, 51th and 66th subframe (starting from the 0th subframe) every 80ms for periods where there is no transmission of SI messages. The corresponding NPUSCH format 1 are scheduled 9 subframes after each NPDCCH transmission. NPUSCH format 1 transmission has a duration of 2 consecutive ms.
NOTE 7: For 15kHz, 12 tones, and QPSK modulation. NPDCCH transmissions are scheduled at the 18th, 34th, 51th, 66th, 98th, 114th, 131th and 146th subframe (starting from the 0th subframe) every 160ms for periods containing SI messages transmission and at the 2nd, 18th, 34th, 51th and 66th subframe (starting from the 0th subframe) every 80ms for periods where there is no transmission of SI messages. The corresponding NPUSCH format 1 are scheduled 9 subframes after each NPDCCH transmission. NPUSCH format 1 transmission has a duration of 1 ms.
