The subject matter relates to a method for transmitting data in packets in a radio communications system, according to which the receipt of data packets from at least two terminals is confirmed by a base station of the radio communications. The confirmation of receipt takes place without an overlap in time, using identical resources.

Method for transmitting data in packets in a radio communications system

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.

Method for controlling a radio transmission

The invention provides an amplifier arrangement which is of multistage design. The output transistor in the output stage has a coupling path between its control input and its controlled path. The coupling path comprises a series circuit comprising a Miller compensation capacitance and a resistance with a controllable resistance value. It is thus possible to ensure stable operation of the amplifier regardless of bias and load conditions while simultaneously reducing the quiescent current drawn.
