By the proposal provided by the embodimeansmission according to an LTE TDD wireless frame; and the LTE TDD wireless frame comprises different zones, wherein each zone occupies one or more sub-frames. By the proposal provided by the embodiment of the invention, when the communication equipment carries out data transmission, the LTE TDD wireless frame comprises different zones and each zone occupies one or more sub-frames, namely, the subnt of the invention, when the communication equipment carries out data transmission, the LTE TDD wireless frame comprises different zones and each zone occupies one or more sub-frames, namely, the sub-frame is taken as cycle, thus realizing the compatibility with the LTE TDD frame structure of the existing LTE system and supporting relay transmission. The LTE TDD frame structure (10ms) provided by-frame is taken as cycle, thus realizing the compatibility with the LTE TDD frame structure of the existing LTE system and supporting relay transmission. The LTE TDD frame structure (10ms) provided bythe embodiment of the invention considers the compatibility with the LTE system and also meets the flexibility of the relay application. the embodiment of the invention considers the compatibility with the LTE system and also meets the flexibility of the relay application.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and communication equipment for supporting relay transmission. Background technique [0002] With the rapid development of high-speed network technology and multimedia technology, the development of wireless network is extremely rapid. The development trend of wireless network gradually evolves from circuit switching to packet switching, and various wireless broadband access technologies emerge in endlessly. The relay technology is one of the key technologies of the B3G / 4G system. Through the relay station, the throughput of the cell can be improved, the coverage of the cell can be increased, and the cost of building a wireless network and operating cost of the operator can be reduced. As shown in FIG. 1 , the existing wireless access network includes three types of devices, namely, a base station controller, a traditional base station, and a traditional t...
