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