Patent ID: 8451765

Claim:
A method for transmitting a multimedia broadcast/multicast service in a single frequency network, comprising: A. sending, by a Radio Network Controller, broadcast/multicast service data to base stations of target cells or sectors, allocating the same time and frequency resources, scrambling code and midamble to the cells or sectors to transmit the broadcast/multicast service data, and distributing information of the allocated resources, the scrambling code and midamble to the base stations of the target cells or sectors and UEs; and B. rotating, by each of the base stations, a broadcast/multicast service burst signal to be sent by a random phase, and sending the rotated signal to the UE using the time and frequency resources allocated by the Radio Network Controller; wherein, the rotation of the broadcast/multicast service burst signal by the random phase is implemented by multiplying the broadcast/multicast service burst complex signal in baseband form, intermediate frequency form or radio frequency form by a complex signal cos(θ)+j*sin(θ), where θ is a phase rotating factor and is a random number or pseudo random number evenly distributed in a range of 0˜2π.
