Radio relay communication method, radio relay station, and radio communication system

Abstract

The invention provides a radio relay communication method, a radio relay station, and a radio communication system. The radio communication system has a radio base station, a mobile station and a radio relay station relaying communication between the radio base station and the mobile station. The radio relay communication method comprises the following steps: a reception step, where a radio frame transmitted by the radio base station, another radio relay station or the mobile station is received; a detection step, where a frame number of the radio frame received in the reception step is detected; a frame generation step, where a radio frame to which the frame number detected in the detection step is set is generated; and a relay transmitting step, where the relay transmitting of the radio frame generated in the frame generation step is performed.

Description

[0001] This application is a divisional application of the application submitted on May 23, 2007, with the application number 200710104861.4, and the title of the invention is "Radio relay communication method, base station and relay station in radio communication system". technical field [0002] The invention relates to a radio relay communication method in a radio communication system, a radio relay station and a radio communication system. Background technique [0003] In recent years, as a radio communication technology, a technology called WiMAX (Worldwide Interoperability for Microwave Access) has attracted attention. WiMAX was developed as a technology for constructing a wireless MAN by enabling communication carriers and user households to be connected by radio instead of telephone lines or optical fiber lines, and enabling MAN (Metropolitan Area Network) of LAN (Local Area Network) interconnected WAN is wireless, and WiMAX can cover an area with a radius of about 5...

Problems solved by technology

In such a case, the planned reception timing at the MS 300 assumed by the BS 100 and the planned reception timing calculated by the MS 300 based on an instruction from the BS 100 represent a point in time that is greatly different, resulting in reception errors of messages and data

[0018] If such a reception error occurs, transmission / reception of redundant control messages, etc., by retransmission control such as HARQ (Hybrid Automatic Repeat Request) increases, resulting in a reduction in the utilization of radio resources and resulting in reductions in throughput such as The communication quality of the
