A method for processing control information and data between a base station and terminals in a system supporting a plurality of multiple access technologies, comprising the following steps: the base station sending a downlink frame to the terminals, wherein the downlink frame comprises at least one downlink multiple access zone, each downlink multiple access zone supports one downlink multiple access technology and associates with one or more uplink multiple access zones in an uplink frame divided into at least two uplink multiple access zones supporting different uplink multiple access technologies, and each downlink multiple access zone comprises a downlink control information and an uplink control message, the uplink control message comprises information of an uplink multiple access technology supported by the associated uplink multiple access zone and allocation information of a corresponding initial access zone; each of the terminals scanning downlink channels, searching a synchronization signal of the downlink multiple access technology supported by the terminal itself, and after establishing synchronization with the base station according to the synchronization signal, obtaining the uplink control message from the downlink multiple access zone corresponding to the downlink multiple access technology supported by the terminal, and according to the information of the uplink multiple access technology supported by the associated uplink multiple access zone within the uplink control message, determining that there is the uplink multiple access technology supported by the terminal, and performing initial network access according to the allocation information of the initial access zone indicated in the uplink control message, otherwise rescanning the channels. the base station sending a downlink frame to the terminals, wherein the downlink frame comprises at least one downlink multiple access zone, each downlink multiple access zone supports one downlink multiple access technology and associates with one or more uplink multiple access zones in an uplink frame divided into at least two uplink multiple access zones supporting different uplink multiple access technologies, and each downlink multiple access zone comprises a downlink control information and an uplink control message, the uplink control message comprises information of an uplink multiple access technology supported by the associated uplink multiple access zone and allocation information of a corresponding initial access zone; each of the terminals scanning downlink channels, searching a synchronization signal of the downlink multiple access technology supported by the terminal itself, and after establishing synchronization with the base station according to the synchronization signal, obtaining the uplink control message from the downlink multiple access zone corresponding to the downlink multiple access technology supported by the terminal, and according to the information of the uplink multiple access technology supported by the associated uplink multiple access zone within the uplink control message, determining that there is the uplink multiple access technology supported by the terminal, and performing initial network access according to the allocation information of the initial access zone indicated in the uplink control message, otherwise rescanning the channels.
