PMCH - Physical Multicast Channel

• For transmission of multicast and broadcast information
• Format is similar to the PDSCH but it is for reception by several mobiles
• Sub-channel spacing is 7.5 kHz and symbol length is doubled
• Modulation QPSK, 16 QAM or 64 QAM

The longer symbol length means a longer cyclic prefix permitting good reception over large cells or for combination of signals broadcast simultaneously over a set of cells.
