摘要
A remote base station system comprising remote radio units and a controller is described. Each of the remote radio units comprises one or more radio frequency (RF) units to exchange RF signals with mobile devices. At least some of the RF signals comprise information destined for, or originating from, a mobile device. The controller comprises one or more modems and is connected to an external network. At least one of the modems is a baseband modem and is configured to pass first data from the external network corresponding to the information. The at least one of the modems is configured to perform real-time scheduling and baseband processing of the first data corresponding to the information to generate second data. The controller is separated from the remote radio units by an intermediate network. The intermediate network comprises a switched Ethernet network over which the second data corresponding to the information is carried in frames between the controller and the remote radio units. The second data may be frequency compressed. The remote radio units are synchronised through the intermediate network with the controller. Cells may be defined comprising one or more of the remote radio units.
