Abstract

The invention discloses a multi-antenna data transmission method based on graded service, and a system and a device thereof. The graded transmission is realized through the graded MIMO design, a relay station equipped by multiple antennas can be utilized for transferring enhanced layer data to coverage range edge users by graded MIMO or simultaneously transferring two-layer data of both the basiclayer and the enhanced layer, and the high-quality receiving of the edge users can be realized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a multi-antenna data transmission method, system and device based on hierarchical broadcast services. Background technique [0002] With the rapid development of mobile communication technology, the requirements for the performance indicators of broadband wireless communication are getting higher and higher. Many advanced technologies such as multiple input multiple output (Multiple Input Multiple Output, MIMO) technology and relay technology are widely used in new In the wireless communication network, at the same time, the research on the multimedia broadcasting service in the wireless cellular network has also received extensive attention. Among them, the multi-antenna technology can effectively improve the spectrum utilization rate of the system through different space-time coding schemes, and increase the capacity without increasing the transmission po...
