Section: 6.8B.2 Scrambling
Content: Scrambling shall be perfomed according to Clause 6.8A.2 with EPDCCH replaced by MPDCCH except that the same scrambling sequence is applied per subframe to MPDCCH for a given block of subframes and is the MPDCCH set number. For an MPDCCH associated with a 2+4 PRB set as defined in [4], is used to generate the scrambling sequence for mapping to REs in 6 PRBs as well as 2 PRBs and 4 PRBs. 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 the MPDCCH. The MPDCCH transmission spans consecutive subframes, including subframes that are not BL/CE DL subframes where the MPDCCH transmission is postponed. For BL/CE UEs, - if the MPDCCH transmission is associated with P-RNTI or SC-RNTI: - for frame structure type 1 and for frame structure type 2 - otherwise - for UEs assuming CEModeA (according to the definition in Clause 12 of [4]) or configured with CEModeA: - for frame structure type 1 and for frame structure type 2 for UEs assuming CEModeB (according to the definition in Clause 12 of [4]) or configured with CEModeB.
