Abstract
The present invention relates to a method and apparatus for testing mobile terminals in an OFDMA system, in which all or part of available downlink radio resources in a cell are transmitted. A processing unit in a test apparatus splits the resources used for transmission into contiguous unities in the frequency domain such that one or more of said unities comprise resources allocated to one or more mobile terminals under test, and at least one of said unities comprise resources allocated to virtual users.
Claims22
A method for testing OFDM mobile terminals, said method comprising:
- splitting radio resources available in a cell of an OFDM system into contiguous unities in the frequency domain, wherein one or more of said unities comprises radio resources allocated to one or more mobile terminals being tested and wherein at least one of said unities comprises radio resources allocated to virtual users;
- and
- transmitting test signals to said one or more mobile terminals on radio resources allocated to the mobile terminals and to the virtual users on radio resources allocated to said virtual users.
A test apparatus for testing mobile terminals in an OFDMA system, said test apparatus comprising:
- a processing unit configured to split radio resources in an OFDMA cell into contiguous unities in the frequency domain, wherein one or more of said unities comprise radio resources allocated to one or more mobile terminals being tested and wherein at least one of said unities comprise radio resources allocated to virtual users;
- and
- a transmitter operatively connected to said processing unit for transmitting test signals to said one or more mobile terminals on radio resources allocated to the mobile terminals and to the virtual users on radio resources allocated to said virtual users.
