Radio relay system and communication method for radio relay system

Abstract

The embodiment of the invention discloses a radio relay system. The system comprises a radio resource control (RRC) layer having a first control device used for coordinating a radio relay station to communicate with user equipment (UE) and a base station. The embodiment of the invention also provides a communication method based on the system at the same time. Through the configuration of relatedrelay functions in the RRC layer of an air interface protocol stack in the embodiment of the invention, radio relay stations can control and regulate radio resources according to the network status while transferring uplink and downlink data so as to rationally utilize the radio network resources and improve the efficiency of data transmission. Meanwhile, the embodiment of the invention also discloses the radio relay system which is also used for realizing the technical effect.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, relates to a wireless relay system and a communication method of the wireless relay system. Background technique [0002] With the rapid development of high-speed network technology and multimedia technology, the development of wireless networks is extremely rapid. In wireless networks, the transmission media for communication between terminals mainly include radio waves and infrared rays. Due to the attenuation of radio waves and the higher the frequency, Radio waves attenuate faster with distance, so high operating frequency will lead to very limited coverage of base stations in the network. In view of this, the existing technology adds wireless relay stations to the network to increase the coverage of the system. [0003] The wireless relay station communicates with the base station through the air interface and forwards the data of the terminal. ...

Problems solved by technology

[0004] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: wireless networks such as LTE cannot support the relay function, and the existing wireless relay station is applied to this type of network, and cannot coordinate between the terminal and the base station. communication between

[0005] In many cases, it is simply to control the relay station to transfer the data between the mobile terminal and the base station. With the rapid development of the wireless network, the complexity of the wireless network is getting higher and higher, and the amount of data exchanged between the networks is also increasing. How to use The reasonable scheduling of wireless network resources by wireless relay stations has become an urgent problem to be solved
