Abstract

Disclosed are a message transmission method, a base station, a terminal and a multi-standard communication system in the present invention. The method includes: according to a coexistence configuration of a multi-standard communication system, generating super-frame configuration information and sub-frame configuration information, wherein the coexistence configuration is a frame structure configuration supporting the coexistence of the multi-standard communication system; according to the super-frame configuration information, configuring part or all of unit frames in super-frames of wireless frames in the multi-standard communication system, wherein the super-frame configuration information is used for indicating the configuration attribute of the unit frames; according to the sub-frame configuration information, configuring sub-frames in the unit frames, wherein the sub-frame configuration information is used for indicating the distribution attribute of the sub-frames; and transmitting a message using the wireless frames. The present invention can solve the problem of message transmission interference caused by disunity of the frame structure when multiple communication systems coexist with each other, and improve the utilization ratio of resources.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for transmitting messages, a base station, a terminal and a multi-communication standard system. Background technique [0002] OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing), as a multi-carrier transmission mode, converts high-speed transmission data streams into low-speed parallel transmission data streams, making the system sensitive to frequency selectivity of multipath fading channels degree is greatly reduced. [0003] Worldwide Interoperability for Microwave Access (WiMAX for short) and Long Term Evolution (Long Term Evolution, WiMAX for short) are two highlights of communication technologies in recent years. The WiMAX system based on OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access) is a system using OFDM technology. From the perspective of frequency domain, differe...
