摘要： The invention relates to a reception method and a receiver used in a TDMA radio system. The receiver receives signals placed in time slots allowing the receiver to establish connections. The receiver receives the signals, which are placed in time slots and vary in strength. The receiver comprises amplification means amplifying the received signals with an amplification coefficient of a particular size. The receiver is arranged to receive connection establishing signals from time slots and to form at least two sets of time slots from the time slots, and the amplification means amplify the signals in different sets of time slots with an amplification coefficient of a different size. The amplification means amplify the signals in the same set of time slots with an amplification coefficient of the same size. The receiver comprises measurement means for measuring the strength of the signal received by the receiver, and placing means for placing the connection establishing signal into the set of time slots based on the strength measurement performed for the received signal.

摘要： The invention relates to a radio system and a method of determining the transmission direction. The radio system comprises at least one base station communicating with terminals within its area by emitting a radiation pattern extending over the whole cell area and directional radiation patterns covering only part of the cell area. The base station transmits base-station-related information on a common control channel to the terminals. In the solution of the invention, the base-station-related information transmitted by the base station comprises a general part and a beam-specific part. The base station uses the radiation pattern extending over the whole cell area when transmitting the general part. Each beam-specific part is transmitted by using a specific radiation pattern. The terminal detects one of more beam-specific parts from the information received from the base station and transmits information about the detection result to the base station, on the basis of which the base station decides which directional radiation pattern to use when communicating with the terminal. The invention enables fast determination of the terminal direction with respect to the base station.
