Abstract: A method of operating a Time Division Multiple Access (TDMA) communication system is disclosed. The system includes a multi-carrier power amplifier. The method includes the steps of logging call activity on each timeslot of each carrier associated with the multi-carrier power amplifier; logging total transmit power of the multi-carrier power amplifier for each timeslot; and logging the data rate of any data calls being carried by the multi-carrier power amplifier. Transmission power is made available for a new call by reducing the transmission power of a data call.

Abstract: The invention relates to a power control device and method for calibrating the power of a transmitter or receiver in a mobile communication network comprising an antenna array, wherein burst signals are transmitted to, or received by, the antenna array. The calibration of the transmission or receiving power of the transmitter or receiver includes a summing step for summing transmission or reception signals of the antenna array, and a common calibrating step for commonly calibrating the summed signals.

Abstract: A receiver comprising means for receiving a first plurality of signals at different frequencies at substantially the same time; and means for comparing a wanted signal at a first frequency with at least one other signal at a frequency similar to that of said wanted signal to provide a measure of interference provided by said at least one other signal.

Abstract: A transmit power control system and method is provided which utilizes an efficient allocation of average output power of a multi-carrier power amplifier (MCPA), the average output power being a weighted average of the actual power over multiple time slots. Periodically, using the efficient allocation system and method, there will he short periods where the desired average output power will exceed the maximum tolerable power of the MCPA, PMCPA. These short periods in which the desired output power will exceed PMCPA, are handled by a system and method which produces a reduced margin between the total power per time slot and PMCPA. This reduced margin allows the MCPA to serve a larger number of users per time slot than conventional MCPAs. Alternatively, the MCPA can serve the same number of users as a conventional MCPA, but with higher demands on output power for each user and/or more efficient use of the MCPA's resources.

Abstract: A dynamic channel allocation method is described in which traffic types are assigned by reference to an acceptable carrier to interference ratio for that traffic type. Where a multiple layer re-use scheme is operative, the allocation takes place on layer basis with traffic being assigned to a layer exhibiting a suitable carrier to interference ratio.
