Abstract: A method for communication to/from a multimode terminal operable to communicate via multiple alternative communication technologies. Each region definition indicates a region name and one or more of the communication technologies and/or operating modes plus an activation range and a deactivation range for the communication technologies and/or operating modes. The multimode terminal determines its position and retrieves a stored region definition relating to the region closest to the multimode terminal's determined position. It then compares its determined position with the activation range and a deactivation range of the retrieved region definition. Based on said comparison, the multimode terminal activates and deactivates the multiple alternative communication technologies and/or operating modes indicated by the retrieved region definition.

Abstract: A transmitter of a cognitive radio comprises a selector for selecting from a memory a channel which is determined free, for a power measurement. A power meter measures the received power from the selected channel. Detection selector compares the measured power and a power of the same channel saved in the memory and selects the channel for detection if the power in the channel is within a predetermined range from the power saved in the memory. A detector performs detection of the channel as a response to the selection for detection. A channel selector selects the channel for communication if the channel is detected unoccupied on the basis of detection. The transmitter communicates in the channel as a response to the selection for communication.

A controller in the transmitter forms and transmits receiver-specific instructions based on data to be delivered and the information on the computing architecture. The controller in the receiver controls processing of the data on the basis of the instructions.

Abstract: The invention relates to a method, a base station and a computer program for selecting a spatial transmission method for a next downlink transmission in a base station. The base station can be a WiMAX, a UMTS or a 3 GPP LTE base station. According to the invention the base station makes a selection between beamforming (BF), space-time coding (STC) or MIMO for a next downlink frame. The selection is based on uplink measurements and feedback information from a particular mobile station whereto the next downlink frame is to be transmitted.

Abstract: The network system of an orthogonal frequency division multiplexing radio system measures a quality of a signal from a user terminal. At least one compared property of the signal is compared with a predetermined threshold. The comparison includes a comparison involving the measured quality. A number of sub-channels for the user terminal is decreased if each comparison operation indicates that a compared property is at the predetermined threshold or within a predetermined range of the threshold. A control signal about a decrease is transmitted to the user terminal. The user terminal transmits with the decreased number of sub-channels as a response to the control signal.
