Patent ID: 8446851

Claim:
A method for transmitting a multimedia broadcast multicast service, comprising the following steps: step one, encoding and modulating, by one or more base stations, original multimedia broadcast multicast service data to be transmitted, and transmitting, by one or more base stations, the encoded and modulated multimedia broadcast multicast service data to one or more transparent relay stations belonging to the one of more base stations via a specified same time and frequency resource; step two, performing, by the one or more transparent relay stations, a relay process for the received multimedia broadcast multicast service data, so as to guarantee that the format of data transmitted by the one or more transparent relay stations is identical to that of the multimedia broadcast multicast service data transmitted by the one or more base stations; step three, after performing the relay process for the multimedia broadcast multicast service data by the one or more transparent relay stations, transmitting, by the one or more transparent relay stations and the one or more base stations, the multimedia broadcast multicast service data via the specified same time and frequency resource simultaneously; and step four, receiving, by a terminal, the multimedia broadcast multicast service data, and processing, by the terminal, the received multimedia broadcast multicast service data to acquire the original multimedia broadcast multicast service data; wherein the step one further comprises the following steps: receiving, by the one or more transparent relay stations, the multimedia broadcast multicast data from the one or more base stations via the specified same time and frequency resource; wherein the terminal performs the following processes to the received multimedia broadcast multicast service data: performing an inverse orthogonal frequency division multiplexing operation, a channel estimation, a detecting process to obtain a constellation symbol level data of the estimated multimedia broadcast multicast service data, and demodulating and decoding the symbol level data of the estimated multimedia broadcast multicast service data.
