The invention comprises: receiving from a user an uplink signal using multiple narrow antenna beams; measuring beam-specific pilot signal powers from the uplink signal for all the beams; and using the measured pilot signal powers to determine which one or ones of the downlink beams is to be used for a downlink signal for the user. | 10-20-2011 |
20110188418 | ANTENNA BEAM - A fixed phase shift for each of a plurality of radio frequency signal components directed to or received from a plurality of antenna elements is formed in a phase shifter. A desired antenna beam pattern with at least one grating lobe is formed on the basis of the phase-shifted radio frequency signal components of the antenna elements in a predefined antenna structure. | 08-04-2011 |
20110159827 | Monitoring Channels - 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. | 06-30-2011 |
20110039579 | Position-Dependent Connectivity Management - 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. | 02-17-2011 |
20110022885 | Methods and Equipment for Fault Tolerant IP Service - An Internet Protocol (IP) terminal, comprises communication means for communicating via an IP network, a processor and memory. The memory contains an operating software for the IP terminal and the processor is configured to execute the operating software. The operating software comprises a normal mode logic for implementing a normal mode operation and a restricted mode logic for implementing a restricted mode operation. The normal mode logic comprises program code for initiating a call of a first type under control of instructions from one or more dedicated servers. The restricted mode logic comprises program code for collecting connection information of other IP terminals and for initiating a call of a second type without instructions from the one or more dedicated servers. | 01-27-2011 |

20100189055 | Apparatus of Multi-Antenna Telecommunication System - An apparatus of a multi-antenna telecommunication system includes a beam forming unit configured to form at least two antenna beams, and a signal feeding unit connected to the beam forming unit and configured to feed beam-specific data streams to the beam forming unit. The beam-specific data streams are allocated to one and the same transceiver of the wireless telecommunication system, and each data stream includes independently and separately encoded data signals. | 07-29-2010 |
20100164759 | Input Arrangement - The invention provides an input device of an electric apparatus and a method of manufacturing an input device, wherein the input device comprises: a key member ( | 07-01-2010 |
20100118763 | Data Transfer - A radio system comprises a transmitter, an intermediate station, and a receiver for data transfer from the transmitter to the receiver. The intermediate station receives at least one data packet addressed to the receiver from the transmitter, transmits each data packet to the receiver, and performs signaling of the receiver to the transmitter in conjunction with the data transfer. | 05-13-2010 |
20090268625 | Communication Method and a Radio System - 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. | 10-29-2009 |
20090247090 | Data Transmission - The transmitter receives information on a computing architecture of a receiver. 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. | 10-01-2009 |
20090154374 | COMMUNICATION OF CONFIGURATION MANAGEMENT NOTIFICATIONS IN A PACKET-SWITCHED NETWORK - A method and devices are provided for communicating configuration management notifications from a network element to a network manager in a packet-switched network. The configuration information of the network element is stored at different time instants having a time interval therebetween. Two sets of configuration information are compared in order to determine changes between the two time instants. The changes are then transmitted to the network manager through a communication connection by using a file-based configuration protocol. | 06-18-2009 |
20090005120 | TRANSMISSION METHOD FOR COMMON CHANNELS - A method and base station arrangement by which broadcast info messages can be transmitted using cyclic delays and a beamformer to the whole cell simultaneously. In the method during the broadcast info transmission cyclic delays are introduced to the transmitted symbols before the symbols are fed to a beamformer. The delayed symbols are transmitted using antennas connected to the beamformer. By utilizing cyclic delays dead zones can be avoided in the cell or sector. The method can be utilized for example in WiMAX, WiFi, UMTS or 3 | 01-01-2009 |
