Section: 5.5.2.1A.4 Mapping to physical resources
Content: The sequence shall be multiplied with the amplitude scaling factor and mapped in sequence starting with to the sub-carriers. The set of sub-carriers used in the mapping process shall be identical to the corresponding PUSCH transmissions using sub-PRB allocations for BL/CE UEs as defined in clause 5.3.4. The mapping to resource elements shall be in increasing order of first, then , and finally the slot number. The value of the symbol index in a slot is 3. For BL/CE UEs, if uplink resource reservation is enabled for the UE as specified in [9], and the Resource reservation field in the DCI is set to 1, then in case of PUSCH transmission with associated with C-RNTI or SPS C-RNTI using UE-specific MPDCCH search space including PUSCH transmission without a corresponding MPDCCH, - In a subframe that is fully reserved as defined in clause 8.0 in [4], the demodulation reference signal transmission is postponed until the next BL/CE uplink subframe that is not fully reserved. - In a subframe that is partially reserved, the demodulation reference signal transmission in a SC-FDMA symbol that is reserved is dropped.
