Data transmitting method for use in e.g. global system for mobile communication system, involves evaluating two subsets of symbol of two receiver devices of two classes, respectively, and transmitting subsets of symbol

摘要

The method involves evaluating two subsets of a symbol of two receiver devices i.e. global system for mobile communication (GSM) mobile stations, of two classes i.e. terminals, respectively. The subsets of the symbol are transmitted by two transmitting modules, respectively, and the symbol is adjusted to one of the receiver devices of one of the two classes. The subsets of the symbol are used for transmitting signaling data and user data to the receiver devices of the classes, respectively. An independent claim is also included for communication system comprising a receiving device and a sending device.
