Method and apparatus for testing mobile terminals in an OFDM system

A test apparatus for testing mobile terminals in an Orthogonal Frequency Division Multiplexing (OFDM) system, said test apparatus comprising:

• a processing circuit configured to split radio resources in an OFDMA cell into contiguous unities in the frequency domain;
• wherein the radio resources of one or more of said contiguous unities in the center of an available cell bandwidth are allocated to one or more mobile terminals being tested;
• and
• wherein the radio resources of at least one of said contiguous unities are allocated to virtual users, said virtual users emulating a load of a cell to create a realistic test environment for the mobile terminals being tested;
• a transmitter operatively connected to the processing circuit, the transmitter configured to transmit test signals to the one or more mobile terminals being tested on the radio resources allocated to the mobile terminals being tested, and to transmit test signals to the virtual users on the radio resources allocated to the virtual users to verify performance requirements in an OFDM system for the one or more mobile terminals being tested under the emulated load.
