The present invention provides a cooperative spatial multiplexing transmission method between a television broadcasting network and a mobile communication network. The cooperative spatial multiplexing transmission method includes: a television broadcasting base station sends a broadcast signal for reception by a user terminal and a mobile communication base station; And / or the closest mobile communication base station feeds back channel quality information; the mobile communication base station sends a cooperative multiplexing transmission request to the TV broadcasting base station when judging that the received feedback information indicates that the multiplexing transmission condition is met; the TV broadcasting base station sends a request to the mobile communication The base station sends the information of the confirmation response; the mobile communication base station coordinates with the TV broadcasting base station to send data to the user terminal on the same frequency point and at the same time. Compared with the prior art, the present invention combines the advantages of the TV broadcasting network and the mobile communication network, and can effectively improve the throughput of the system in the TV broadcasting and mobile communication hybrid network through the collaborative space multiplexing transmission technology scheme of the two. and spectral efficiency.
Description
technical field [0001] The invention relates to a communication technology, in particular to a space multiplexing transmission method coordinated by a television broadcasting network and a mobile communication network. Background technique [0002] With the rapid development of the world's economy and culture, mobile users' demand for information services is increasing rapidly; in wireless networks, more than 66% of users' total demand for mobile information services comes from video services, and more than 90% of users' video service needs are concentrated 10% of certain video content. [0003] In order to cope with the rapid growth of demand for information services, the optimal transmission of mobile information services cannot be achieved by relying solely on traditional broadcast networks or traditional two-way communication networks. The traditional broadcasting network adopts a large-area network, which has a large coverage area and high efficiency of one-way broadca...
