Abstract: The present invention relates to a method for operating a base station transceiver of a cellular radio communication system in controlling transmission of a radio signal to a user equipment, the method comprising determining frequency-hopping control information that is indicative of a hopping-frequency set of frequency sub-bands of a downlink frequency band of a downlink channel of the cellular radio communication system, which are to be used for transmission of consecutive radio signal segments of the radio signal to the user equipment, and that is indicative of a hopping time order of the frequency sub-bands of the hopping frequency set, which is to be used for the transmission of the consecutive radio signal segments of the radio signal to the user equipment; wherein determining the frequency-hopping control information comprises ascertaining user-equipment hopping-limitation information that is indicative of one or more of the frequency sub-bands of the downlink frequency band that are to be excluded fro

Abstract: An arrangement including a first circuit board having a contact surface for contacting of a connecting element, a second circuit board, and a connecting element. The contact surface has a central contact point and a concentric ring surrounding the central contact point. The connecting element which is electrically contacted at a first side with the second circuit board and which at a second side in opposite relationship to the first side includes a first spring element at least one second spring element. The first spring element is electrically contacted with the central contact point of the first circuit board and the at least one second spring element is electrically contacted with the concentric ring of the first circuit board.

Abstract: The invention relates to a portable computer unit, in particular a PDA, with an integrated radio unit, at least one antenna and a housing for the radio unit with a lower housing piece and a cover, whereby the at least one antenna is integrated in the housing.
