Transmission of MBMS in an OFDM communication system

摘要

The invention provides for a method of identifying a cyclic prefix to UEs in an OFDM communication system. The cyclic prefix has a dynamically variable length. The method includes, within an OFDM cell, transmitting MCCH scheduling information in a system information block in an OFDM broadcast channel, and using the MCCH scheduling information to receive the MCCH, wherein the MCCH contains MTCH scheduling information to indicate to the UE which sub-frame carries MTCH.

1. A method, in a mobile communication system, of orthogonal frequency division multiplexing (OFDM) data transmission, the method comprising:
a transmitter transmitting a plurality of sub-frames, in which the cyclic prefix length of each symbol can vary dynamically, and including a normal-length cyclic prefix in a first n OFDM symbols in each of the plurality of sub-frames, n being an integer having a value less m, where m is a number of OFDM symbols in each of the plurality of sub-frames, and including an extended-length cyclic prefix in the remaining m-n OFDM symbols, wherein MBMS signals are transmitted in the remaining m-n OFDM symbols; wherein n is 2 or 3.
