Method and apparatus for transmitting and receiving layered modulation data

Abstract

The embodiment of the invention discloses a hierarchical modulated data transmitting and receiving method and a device thereof; wherein the hierarchical modulation signal transmitting method includes the following steps: receiving the base-hierarchy data and the reinforced-hierarchy data formed after hierarchical modulation by a base station from a base station; picking up the reinforced-hierarchy data from the base-hierarchy data and the reinforced-hierarchy data formed after the hierarchical modulation by the base station; and sending the picked reinforced-hierarchy data to a terminal. The terminal far from the base station within the coverage of the base station receives the reinforced-hierarchy data formed after the hierarchical modulation by the base station from a relay station, and receives base-hierarchy data formed after the hierarchical modulation by the base station from the base station. Therefore, the hierarchical modulation signal transmitting and receiving method and the device can realize that the terminal far from the base station within the coverage of the base station can receive the base-hierarchy data and the reinforced-hierarchy data formed after the hierarchical modulation by the base station from the base station at the same time while saving frequency spectrum resources.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a layered modulation data transmission and reception method and equipment. Background technique [0002] With the increasing maturity and commercialization of wireless communication technology. Cellular mobile communication, wireless local area network, wireless metropolitan area network and other wireless communication means have been widely used in various fields of people's production and life, providing people with more and more convenient means of communication and exchange anytime and anywhere. Mobile communication technology has experienced the first generation of analog mobile communication (1G), the second generation of digital mobile communication system (2G), and the third generation of multimedia mobile communication system (3G), which is currently growing at a high speed, is moving beyond 3G and 4G broadband mobile communication system development.

Problems solved by technology

In this prior art, remote users can enjoy high-quality services by forwarding data through a relay station installed between the base station and the terminal. The basic layer data sent from the base station can be directly received, while in the existing technical solution, the terminal only receives the data of the relay station, resulting in the waste of this part of the basic layer data of the base station, resulting in a waste of spectrum resources
