摘要： Method and arrangements for scheduling transmission resources in a first node in a cell comprised within a wireless communication network. The first node is arranged to communicate over a communication channel with at least one user equipment within the cell. The communication is made by using a frame comprising uplink resources and downlink resources with a switching point between the downlink resources and the uplink resources. The method comprises the step of obtaining a parameter referring to the expected transmission quality of the communication and/or the expected coherence properties of the communication channel. The method also comprises scheduling a transmission on an uplink or downlink resource. The resource is located on a time distance from the switching point. The time distance is based on the obtained parameter.

摘要： The presence of spread spectrum signals in a given frequency range is detected in a receiver by receiving a signal; determining for a measurement frequency an indication signal; and using it as an indication of the presence of spread spectrum signals having a carrier frequency equal to the measurement frequency. An in-phase signal and a quadrature signal are provided by mixing the received signal with an oscillator signal having the measurement frequency; at least one of these signals is phase shifted; a sum signal and a difference signal are generated; and the sum signal is multiplied by the difference signal and low pass filtered. In this way a method and a circuit of detecting the presence of spread spectrum signals in a given frequency range are provided, which are simple and fast enough to be used in low-cost cognitive radios.

摘要： Methods and apparatus are provided for establishing a connection between a scanner device and a pager device over a sequence of hop channels. The scanner device is repetitively activated and a hop channel is selected from the sequence of hop channels as a function of a present phase. A determination is made as to whether the selected hop channel is a forbidden hop channel. A substitute hop channel is selected from the sequence of hop channels as the selected hop channel if the selected hop channel is a forbidden hop channel. The selected hop channel is monitored for receipt of a paging message during the present phase.

摘要： An apparatus in a wideband radio transceiver for mitigating interference between a wideband radio operating in a wide frequency band and a narrowband radio operating in a narrow frequency band within the wide frequency band. The effects of transmissions by the wideband radio on the narrowband radio are reduced by creating by the wideband radio, a transmitter notch of decreased transmit power centered at a frequency in the wide frequency band that is fixed in relation to the wideband carrier frequency. The wideband carrier frequency is then adjusted so that the transmitter notch is aligned with the second radio's narrow frequency band. The effects of transmissions by the narrowband radio on the wideband radio are reduced by creating by the wideband radio, a fixed receiver notch of decreased receiver gain in the wideband receiver, and aligning the narrowband signal with the fixed receiver notch.

摘要： A method and apparatus for managing traffic in a network to and from a remote communications device with limited power supply resources. A controller determines the existing power level of the device and uses the determination to control data transmission to and from the device. Data may be transmitted and received by the device by determining the power required to complete a transmission or reception. The controller then determines whether to send the data, redirect the data, cancel the data transmission, or transmit only a portion of the data. The decision is made as to which option to choose based on the amount of power available to complete the data transmission.

摘要： A terminal that is capable of communicating on a first system that is an ad-hoc communication system, and a second system that is a mobile communication system is operated by receiving one or more dynamically changing values from a network part of the second system; and using the one or more dynamically changing values to determine one or more parameters that characterize one or more ad-hoc communication operations in the first system. The ad-hoc communication operations may, for example, be an inquiry operation, a paging operation, and a scanning operation. The one or more parameters that characterize these operations may include when the operation will occur, and on what frequency it will be carried out. The dynamically changing values may include a clock value and/or a frame counter value. In this way, timing and/or frequency uncertainty may be eliminated when performing the operations in the first system.

摘要： A dual-radio communication apparatus has a first radio device, such as a Bluetooth radio, for use in a first frequency band, and a second radio device, such as a Globalstar satellite radio, for use in a second frequency band, which is proximate to the first frequency band. The communication apparatus also has a controller coupled to the first and second radio devices. The first radio device may comprise a frequency-hopping spread-spectrum transmitter. Moreover, the first radio device has a first operating mode employing a first frequency range. The first radio device also has a second operating mode employing a second frequency range, which is smaller than the first frequency range. The controller is adapted to set the first radio device in its second operating mode, when the second radio device is in operation, and otherwise set the first radio device in its first operating mode.

摘要： A system and method for resource management and traffic control in time division duplex communication systems is discloses. A multi-radio base station maintains communication links with a plurality of remote terminals, each of which requests a specific bandwidth ratio. A controller analyzes the requested bandwidth ratios and allocates slots in the base station radios according to a packing scheme that synchronizes the transmission and receive timing of the multiple base station radios communication links. The resource management and traffic control techniques may be applied to a variety of communication devices communicating over a variety of interfaces, such as WLAN or BLUETOOTH. Furthermore, the techniques can be employed with devices communicating with two or more remote devices via different interfaces.
