Section: 5.4.3 Mapping to physical resources
Content: The block of complex-valued symbols shall be multiplied with the amplitude scaling factor in order to conform to the transmit power specified in Clause 5.1.2.1 in TS 36.213[ Evolved Universal Terrestrial Radio Access (E-UTRA); Physical layer procedures ]  [4], and mapped in sequence starting with to resource elements. PUCCH uses one or more resource block in each of the two slots in a subframe. Within the physical resource block(s) used for transmission, the mapping of to resource elements on antenna port and not used for transmission of reference signals shall be in increasing order of first , then and finally the slot number, starting with the first slot in the subframe. The relation between the index and the antenna port number is given by Table 5.2.1-1. For non-BL/CE UEs, except for PUCCH format 4, the physical resource blocks to be used for transmission of PUCCH in slot are given by For BL/CE UEs, PUCCH is transmitted with repetitions. - The BL/CE UE is not expected to transmit with when ce-PDSCH-14HARQ-Config is configured. The PUCCH transmission spans consecutive subframes, including subframes that are not BL/CE UL subframes where the UE postpones the PUCCH transmission if . If the BL/CE UE is configured with ce-HARQ-AckDelay-r17 indicating Alt-2e, the UE does not postpone the PUCCH transmission. - The quantity is given - by the higher layer parameter pucch-NumRepetitionCE-Format1 for PUCCH format 1/1a and pucch-NumRepetitionCE-Format2 for PUCCH format 2/2a/2b, if configured. Otherwise - by the higher-layer parameter pucch-NumRepetitionCE-Msg4-Level0-r13, pucch-NumRepetitionCE-Msg4-Level1-r13, pucch-NumRepetitionCE-Msg4-Level2-r13 or pucch-NumRepetitionCE-Msg4-Level3-r13. - 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 PUCCH transmission is postponed until the next BL/CE uplink subframe that is not fully reserved. - In a subframe that is partially reserved, the reserved SC-FDMA symbols shall be counted in the PUCCH mapping but not used for transmission of the PUCCH. The physical resource blocks to be used for transmission of PUCCH in subframe within the consecutive subframes are given by where is the absolute subframe number of the first uplink subframe intended for PUCCH. The variable depends on the PUCCH format. - Formats 1, 1a and 1b: - Formats 2, 2a and 2b: - Format 3: - Format 5 (non-BL/CE UEs only): For non-BL/CE UEs, for PUCCH format 4, the physical resource blocks to be used for transmission of PUCCH in slot are given by where is obtained from [4]. Mapping of modulation symbols for the physical uplink control channel for PUCCH formats 1 – 3 is illustrated in Figure 5.4.3-1. In case of simultaneous transmission of sounding reference signal and PUCCH format 1, 1a, 1b, 3, 4 or 5 when there is one serving cell configured, the shortened PUCCH format shall be used where the last SC-FDMA symbol in the second slot of a subframe shall be left empty. In case of guard period for narrowband or wideband retuning for BL/CE UEs, if an SC-FDMA symbol is left empty due to guard period, the SC-FDMA symbol shall be counted in the PUCCH mapping but not used for transmission of the PUCCH. The SC-FDMA symbol affected by the guard period can be the first SC-FDMA symbol in the first slot of a subframe and/or the last SC-FDMA symbol in the second slot of a subframe. For BL/CE UEs communicating over NTN, for PUCCH transmission, for frame structure type 1, after a transmission duration of time units (which may include subframes that are not BL/CE UL subframes), a transmission gap of time units shall be counted for the PUCCH resource mapping but not used for transmission of the PUCCH, according to the single UE capability ntn-SegmentedPrecompensationGaps-r17, as specified in 3GPP TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [9]. The quantity is provided by higher layers, and the quantity is configured by higher layers based on the UE capability, if signalled.
