In a method for configuring a Software Defined Radio (SDR) capable user equipment, the SDR capable user equipment wirelessly loads an SDR program from a radio access network. The SDR capable user equipment executes the loaded SDR program, the SDR program on execution configuring the SDR capable user equipment to support a desired wireless communication technology. The SDR capable user equipment loads the SDR program using a dedicated SDR configuration channel, the dedicated SDR configuration channel being disjoint with any communication channel defined by the desired wireless communication technology. The SDR capable user equipment scans a predetermined frequency spectrum searching a broadcasted beacon. The SDR capable user equipment receives the broadcasted beacon and tunes to the dedicated SDR configuration channel or a subchannel thereof pointed to by a pointer for loading the SDR program.

Configuring an SDR capable user equipment

A method for transmitting payload and/or control data in downlink and/or uplink directions between a base station entity and a user equipment of a mobile communication network includes: in a first step, the user equipment detects the at least one downlink control signal and the specific downlink radio transmission frequency as an initial downlink radio transmission resource; and in a second step, subsequent to the first step, the user equipment receives downlink control information from the base station entity. The content or value of the downlink control information indicates or defines an initial uplink radio transmission resource.
