Section: 6.10.3.1 Sequence generation
Content: For antenna port 5, the UE-specific reference-signal sequence is defined by where denotes the assigned bandwidth in resource blocks of the corresponding PDSCH transmission. The pseudo-random sequence is defined in clause 7.2. The pseudo-random sequence generator shall be initialised with at the start of each subframe where is as described in clause 7.1 TS 36.213[ Evolved Universal Terrestrial Radio Access (E-UTRA); Physical layer procedures ]  [4]. For any of the antenna ports , the reference-signal sequence is defined by . The pseudo-random sequence is defined in clause 7.2. The pseudo-random sequence generator shall be initialised with at the start of each subframe. For BL/CE UEs, the same scrambling sequence is applied per subframe to the UE-specific reference-signal sequence for a given block of subframes. The subframe number of the first subframe in each block of consecutive subframes, denoted as , satisfies . For the block of subframes, the scrambling sequence generator shall be initialised with where and is the absolute subframe number of the first downlink subframe intended for PDSCH. The PDSCH transmissions span consecutive subframes, including subframes that are not BL/CE DL subframes where the PDSCH transmission is postponed. For a BL/CE UE configured in CEModeA, . For a BL/CE UE configured with CEModeB, for frame structure type 1 and for frame structure type 2. The quantities , , are given by - if no value for is provided by higher layers or if DCI format 1A, 2B or 2C is used for the DCI associated with the PDSCH transmission - otherwise The value of is zero unless specified otherwise. For a PDSCH transmission on ports 7 or 8, is given by the DCI format 2B, 2C, 2D, 6-1A, 7-1E, 7-1F and 7-1G in TS 36.212[ Evolved Universal Terrestrial Radio Access (E-UTRA); Multiplexing and channel coding ]  [3] associated with the PDSCH transmission. In the case of DCI format 2B or 7-1E, is indicated by the scrambling identity field according to Table 6.10.3.1-1. In the case of DCI format 2C or 2D, is given by Table 5.3.3.1.5C-1, Table 5.3.3.1.5C-2 or Table 5.3.3.1.5C-6 in TS 36.212[ Evolved Universal Terrestrial Radio Access (E-UTRA); Multiplexing and channel coding ]  [3]. In the case of DCI format 7-1F or 7-1G, is given by Table 5.3.3.1.22-1, Table 5.3.3.1.22-2, Table 5.3.3.1.22-3 or Table 5.3.3.1.5C-6 in TS 36.212[ Evolved Universal Terrestrial Radio Access (E-UTRA); Multiplexing and channel coding ]  [3]. For a PDSCH transmission on ports 11 or 13, is given by the DCI format 2C or 2D in TS 36.212[ Evolved Universal Terrestrial Radio Access (E-UTRA); Multiplexing and channel coding ]  [3] associated with the PDSCH transmission where is given by Table 5.3.3.1.5C-2 in TS 36.212[ Evolved Universal Terrestrial Radio Access (E-UTRA); Multiplexing and channel coding ]  [3].
