Abstract: The method comprises setting a threshold value, dividing the combined signal into blocks, comparing the values of each block with the set threshold value and if the threshold value is exceeded, decorrelating the block where the threshold value was exceeded and a pre-determined number of channelization codes, which have a pre-determined spreading factor. The decorrelation result is normalized to determine first weighting coefficients. The method also comprises comparing each combination of a first weighting coefficient and a related channelization code with the set objectives and determining second weighting coefficients for the downlink transmissions selected as a result of the comparison. The examined block is re-formed using combinations of the channelization codes and the weighting coefficients that were determined.

Abstract: A packet transmission method and apparatus for transmitting data packets via a telecommunication network are described, wherein the quality of a received data packet is judged and the data packet is tagged in response to the result of the quality judgment. The tagging is performed by adding a dropping information, wherein a tagged cell is dropped on the basis of the dropping information and a predetermined dropping condition such as a transmission congestion situation and/or an overuse of a contract of a particular connection. In the uplink direction, the quality judgment can be based on an error check or a comparison of a quality base likelihood parameter with a threshold value. In the downlink direction, the quality judgment can be performed on the basis of an uplink quality parameter and/or a downlink power control status. Accordingly, in case of a congestion and/or an overuse of a particular connection, low quality transmission packets are dropped first to thereby reduce traffic.

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.

Abstract: A base station receiver and a reception method in a CDMA cellular radio system includes, in each cell, at least one base station communicating with a plurality of mobile stations situated within its area. The base stations measure the direction angle of a signal arriving from each mobile station with respect to the base station, and communicate with the mobile stations using antenna beams that change in time. The angles of the greatest gain of the beams are adjusted according to signal components arriving from the mobile station. In order to provide detection of good quality without a great deal of calculation, the detection of the desired signal utilizes simultaneously several signals received from different mobile stations taking into account the incoming direction of the signals when selecting the signals.

Abstract: The coverage area of the base station of a cellular radio system is expanded in a very simple and easily implementable way by utilizing the cabling present in a community antenna system, so that the community antenna system and a repeater connected thereto are used for transmitting telecommunication signals between the base station and a subscriber unit served by the system. The base station can also transmit on the control channel to the repeater information as to which radio channel and which power level the repeater should at each time repeat the signals it receives, to ensure that the signals intended for a specific subscriber unit are repeated on a traffic channel and power level suitable for the purpose. The base station can reduce the power level used by the repeater to such a level that a plurality of repeaters utilizing the same traffic channel can be placed close to one another without disturbing one another.
