Section: 6.5 Physical multicast channel
Content: The physical multicast channel shall be processed and mapped to resource elements as described in clause 6.3 with the following exceptions: - No transmit diversity scheme is specified. - Layer mapping and precoding shall be done assuming a single antenna port and the transmission shall use antenna port 4. - The PMCH can only be transmitted in the MBSFN region. For PMCH with Δf = 15 kHz, the index in the first slot in the MBSFN subframe fulfils where is equal to the value given by the higher layer parameter non-MBSFNregionLength [9]. - The PMCH shall use extended cyclic prefix. - The PMCH is not mapped to resource elements used for transmission of MBSFN reference signals. - In clause 6.3.1, for Δf = 1.25 kHz and Δf ≈ 0.37 kHz, the scrambling generator shall be initialised at the start of each slot. - For the following exception applies to clause 6.3.5: - The text "which meet all of the following criteria in the current subframe" shall be replaced by "which meet all of the following criteria in the current slot" - The mapping to resource elements on antenna port not reserved for other purposes shall be in increasing order of first the index over the assigned physical resource blocks and then the index . - For PMCH symbols belonging to an MBSFN area with configured, shall be replaced by in clauses 6.3, 6.10.2, and 6.12.
