Problems solved by technology

Digital relay stations need to access the network first to participate in data relay. At present, there is no negotiation mechanism on how digital relay stations can access the network and perform relay functions. There is also the problem that the base station cannot control the work of relay stations.

Embodiment Construction

[0077] For the convenience of explaining the present invention, Fig. 2 and Fig. 3 show two kinds of frame structure diagrams that can be used in the communication of the wireless communication system in the present invention, but the actual system is not limited to these two frame structures. In addition, these two embodiments only provide the situation that the data sent between the base station and the relay station only passes through two hops, but not forwarded by other stations. In the actual application system, the data sent between the base station and the relay station may pass through two hops. The above multi-hop transmission, but there is no substantial change when using the method of the present invention in the case of multi-hop transmission. As shown in FIG. 2 or FIG. 3 , the shaded box part in the figure indicates transmitting data, the white box part indicates receiving data, and the dashed box part indicates an idle state. As shown in FIG. 2 , the base station...

Abstract

The present invention discloses a method to start and stop relay functions of wireless relay stations in wireless communication systems. In the method, a relay station and a base station can initiate a request for starting or stopping relay functions of the relay station. Firstly, the relay station and the base station negotiate to start or stop relay functions of the relay station. The relay station determines to arrange its operating mode into relay or terminal mode according to negotiation results. Moreover, the present invention discloses a relay station, which arranges its operating mode according to received request information on starting or stopping relay functions. The present invention fulfills remote control over relay station operating state and facilitates users to control their relay stations.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a method for starting and stopping the relay function of a wireless relay station in the wireless communication system, and a wireless relay station based on the method. Background technique [0002] In a wireless communication system, base stations and mobile terminals communicate wirelessly through electromagnetic wave signals. Because electromagnetic wave signals are affected by factors such as path attenuation, building occlusion, and the environment, the wireless signal strength becomes weaker in some places, and the communication quality of mobile terminals located in these areas will decline. As people's demand for broadband communication and wireless bandwidth increases, higher and higher carrier frequencies are used in new protocols and systems. However, since the attenuation during electromagnetic wave transmission increases with the increase of its frequency,...
