Problems solved by technology

[0004] However, in the WiMAX system, due to the high-frequency transmission, the attenuation of electromagnetic waves is serious, so the coverage of the system is small, and in the initial stage of networking, due to the small number of users and the low load, the coverage of the system is limited. Time-frequency resources are likely to be underutilized

Embodiment 1

[0096]The basic frame structure of the base station in the present invention is shown in Figure 8, and the frame structure of the relay station is shown in Figure 9, wherein, RSTTG represents the time required for the relay station to change from the sending state to the receiving state process, and RSRTG represents the time required for the relay station to switch from the receiving state For the time required in the process of sending the state, the base station frame includes the base station uplink subframe and the base station downlink subframe, and the base station downlink subframe is divided into two parts, one part is used for the base station to provide services to the terminals within its coverage, called the downlink terminal The subframe, the other part is used to provide services for the relay station, which is called the downlink relay subframe; similarly, the uplink subframe of the base station is also divided into two parts, one of which is used to provide servi...

Embodiment 2

[0102] The time sequence of the uplink terminal subframe and the uplink relay subframe in the uplink subframe of the base station in Figure 8 can be interchanged. You need to switch the sending and receiving state twice.

Embodiment 3

[0104] In addition to the methods shown in Fig. 8 and Fig. 9 for accessing sub-channels, the method shown in Fig. 10 can also be used, in Fig. 10 (a) is a base station frame, (b) is a relay station frame. Similarly, access sub-channels may also be located in other locations.

The method of utilizing relay station to realize mobile communication is also disclosed.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a device and method for realizing mobile communication by using a relay station. Background technique [0002] With the gradual improvement of people's demand for wireless communication, Broadband Wireless Access (BWA) technology is gradually becoming one of the hotspots in the current communication technology development. Orthogonal Frequency Division Multiplexing Access (OFDMA) has been adopted by more and more broadband wireless access standards due to its unique advantages, such as the Global Interoperability for Microwave Access based on the IEEE 802.16 protocol ( The Worldwide Interoperability for Microwave Access (WiMAX) system uses OFDMA as one of its multiple access methods. [0003] The air interface of the WiMAX system adopts the IEEE 802.16 standard, and the structure of the base station frame and the corresponding terminal frame using OFDMA in the Time Division Dup...
