Abstract: A simulation method for the resolution of the power control convergence problem. The power to be transmitted by each mobile station and each base station to assure a proper Qos in the system are computed in an iterative way. At each iterative step, the powers to be received are derived from the level of interference received at the previous iterative step by each network element. Once this is done for each network element, the interference levels are then refreshed. The iterations stop when the biggest gap between estimated and observed interference levels is below a given threshold. One embodiment includes deriving in one step all the power levels to be transmitted by one base station towards many users, assuming a given stable extra cell interference level. In addition, the invention includes a method for taking the dynamic range of power control in both uplink and downlink, and a method for simulation of power control while in the soft handover.

Abstract: A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency band search schedule. Initially, the communications device registers with a less preferred service provider in a first frequency band. While remaining registered with the less preferred service provider, the device examines several frequency bands in the order specified by the frequency band search schedule. A frequency band is examined by dividing the frequency band into many sub-bands, and by locating the strongest signal above a threshold within the sub-band being examined. The examination continues until a second frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider. The category of service provider may be identified and displayed on the communication device.

Abstract: Even when data are transmitted between communication apparatuses, the data time intervals can be synchronized between the transmitting and receiving sides. Information that pertains to the interval of data transmitted from an information apparatus is appended to data, and that data is transmitted. A communication apparatus on the side of a communication partner that receives the data transmits data to an information apparatus on the basis of the received information that pertains to the interval of data. Variations of data intervals can be suppressed, and the data intervals can be synchronized between the transmitting and receiving sides.

Abstract: A receiver generates two metrics, one that is used to control the gain of an amplifier and the other that is used to determine the presence of narrowband interference, such as IMD. The two metrics may represent analog-to-digital converter (A/D) saturation and average signal strength, either of which may be used to control gain or to detect the presence of narrowband interference.

Abstract: To enable a use of a two-band type mobile telephone with a dual radiation circuit, a selector switch is placed between this dual radiation circuit and transmission channels in each of these bands. Given the emergence of the second harmonic resulting from the presence of the selector switch, the undesirable components are filtered with a filter. A part of the reactive components of this filter is between the radiating circuit and the selector switch, while the other part is in the channel to be filtered. Depending on the nature of the channel, the other part in the channel to be filtered has different values.

Abstract: An apparatus for coupling signals to a transmission line, such as a power line (120). The apparatus comprises an input for receiving a wanted signal; a first coupler for coupling the wanted signal (Vmain) onto the line at a first position (Y); a cancelling means (WB, WR, WY), coupled to the input, for deriving a cancelling signal (Vaux) from the wanted signal; a second coupler for coupling the cancelling signal onto the line at a second position (X), spaced from the first position; wherein the wanted signal and the cancelling signal destructively combine in a single direction of propagation along the line while enabling the wanted signal to propagate in the other direction along the line. The apparatus can be used to minimise radiation from an unshielded part of an electricity distribution network, such as substation (100), or to allow re-use of a frequency band on other power lines.

Abstract: A wireless base station includes a determining unit, a first calculation unit and a control unit. The determining unit determines a direction in which a specified mobile station that is to be spatially-multiplexed is located. Then, the first calculating unit calculates a first parameter group, used to form a first directional pattern for each already connected mobile station that should be spatially-multiplexed with the specified mobile station. The first directional pattern is such that a null point is formed in the determined direction. After a link channel allocation has been transmitted to the specified mobile station, the control unit performs control, so that transmission is performed to each already connected mobile station by forming the corresponding first directional pattern and further by reducing transmission power uniformly in all directions.
