摘要： A method includes receiving a signal including a two-dimensional signal pattern in a time-frequency representation, wherein the two-dimensional signal pattern includes a first reference signal at a predetermined first position in the two-dimensional signal pattern and at least one second reference signal at a predetermined second position in the two-dimensional signal pattern. The first reference signal includes cell identification information of a target cell of a cellular radio system and the at least one second reference signal includes cell identification information of at least one interfering cell of the cellular radio system. The method further includes determining a first noise covariance measure based on the first reference signal, determining at least one second noise covariance measure based on the at least one second reference signal, and mitigating an interference included in the received signal based on the first noise covariance measure and the at least one second noise covariance measure.

摘要： Described devices and techniques provide noise whitening in a communication device. The noise whitening is performed by a noise whitening unit that receives signals on a first path associated with a first antenna and signals on a second path associated with a second antenna. The received signals may include radio signals and channel coefficient signals. The noise whitening unit may perform noise whitening of the received signals in consideration of a covariance of the interference and noise associated with the received radio signals.

摘要： A method for controlling a transmit power in a radio communications system includes receiving a request to increase a transmit power of an uplink channel and determining whether the transmit power was at a maximum upon receipt of a previous request to increase the transmit power preceding the received request. If the transmit power was not at the maximum upon receipt of the previous request, the transmit power is increased by a first step size and if the transmit power was at the maximum upon receipt of the previous request, the transmit power is increased by a second step size greater than the first step size.
