Abstract: A radio receiver apparatus of a cellular network includes a channel estimator configured to calculate channel estimates on the basis of a common pilot channel. The apparatus further includes a weight calculation unit configured to calculate a weighting factor on the basis of a signal power of the common pilot channel and control data depending on a transmit signal power of a dedicated data channel. The control data is signaled by the cellular network to the radio receiver apparatus. The radio receiver apparatus further comprises a combiner that combines the signals from multiple cells by using the channel estimates and the weighting factor.

Abstract: A method of operating a Rake receiver circuit includes determining a first property of a first signal received over a dedicated channel and over a first transmission path. The method further includes determining a delay profile of a second signal and determining, on the basis of the delay profile and the first property, if the first transmission path is to be assigned to a Rake finger of the Rake receiver circuit.

Abstract: A method codes data in a transmitted signal. The transmitted signal comprises multiple subcarriers with orthogonal frequencies. The signals are modulated corresponding to a given subset of the subcarriers of the transmitted signal in order to encode information. The signal is modulated corresponding to least one reserved subcarrier depending on at least one optimization criterion relating to a quality of the overall transmitted signal. In order to enhance the quality of the transmitted signal, the optimization criterion depends on at least one first quantity relating to a peak-to-average-power ratio of the transmitted signal and on at least one second quantity relating to an out-of-band power of the transmitted signal.

Abstract: At least one radiation pattern is rotated at a first radio station for the purpose of sampling a predefined angular range. At a first time of rotation, a second radio station is detected with a first angular position within the angular range corresponding to the first time. The second radio station determines a first quality value which can be assigned to the first angular position and reports the first quality value back to the first radio station. The first quality value is available for evaluation at the first radio station at a second time corresponding to a second angular position of the radiation pattern. The first radio station controls the speed of rotation of the at least one radiation pattern for subsequent rotations so that the first angular position corresponds to the second angular position.
