Embodiment Construction

[0127] The present invention provides a wireless relay communication system and method. In the wireless relay communication system, the communication system models of RS, BS, and MS / SS are shown in Fig. 4, Fig. 5 and Fig. 6, and Fig. 4 is the downlink single RS Figure 5 shows the case of an uplink single RS, and Figure 6 shows the case of multiple RSs. In this communication system model, RS and BS, MS / SS adopt FDD / TDM (time division multiplexing) / TDMA (time division multiplexing access) to communicate.

[0128] BS downlink and RS uplink use frequency f1, BS uplink and RS downlink use frequency f2; RS accesses BS as a MS / SS, and MS / SS accesses BS through wireless transfer through RS. In the FDD mode, there are four situations of mutual interference in network system communication as shown in Figure 7(a)-(d). Wherein, TX represents a transmitting module, and RX represents a receiving module.

[0129] For the convenience of subsequent description, in the above three communicati...

Abstract

The related wireless transfer communication method comprises: in down and up subframe of BS physical layer frame structure, setting down and up transfer areas; setting down / up transfer area on down / up subframe of BS physical layer frame structure to define and receive the transfer data time slot of BS down / up transfer area; among BS, RS and UE, using the said set BS and up-down physical layer frame of RS for wireless transfer communication by FDD way. This invention can ensure the transfer communication without interface.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless relay communication system and method. Background technique [0002] IEEE 802.16 is the first broadband wireless access standard, which mainly includes two versions: one is the broadband fixed wireless access version 802.16-2004 of the 802.16 standard, and the other is the broadband mobile wireless access version 802.16e of the 802.16 standard. Only two network elements are defined in the 802.16-2004 standard, specifically BS (base station) and SS (subscriber station); in the 802.16e standard, only two network elements are also defined, specifically BS and MSS (mobile subscriber station). stand). [0003] At present, the 802.16 Multihop Relay SG (802.16 Multihop Relay Research Group) only proposed the concept of RS (Relay Station) for WiMAX (Global Interoperability of Microwave Access). The relay communication entity of the BS, thereby expandin...
