Section: 5.5.2.2.2 Mapping to physical resources
Content: The sequence shall be multiplied with the amplitude scaling factor and mapped in sequence starting with to resource elements on antenna port . The mapping shall be in increasing order of first, then and finally the slot number. The set of values for and the relation between the index and the antenna port number shall be identical to the values used for the corresponding PUCCH transmission. The values of the symbol index in a slot are given by Table 5.5.2.2.2-1. Table 5.5.2.2.2-1: Demodulation reference signal location for different PUCCH formats. For BL/CE UEs, if uplink resource reservation is enabled for the UE as specified in [9], then in case of PUCCH transmission with associated with C-RNTI or SPS C-RNTI using UE-specific MPDCCH search space including PUCCH 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.
