The present invention relates to a method in a CDMA-based communication system for power allocation and control of the downlink channels of a base station having a fixed maximum permitted downlink power level. The method includes the steps of estimating the total needed downlink power for a subsequent time interval and, if necessary, restricting the downlink power for selected subsets of user equipments by means of rejecting their requests for a downlink power increase. Admission and congestion control is done by means of analyzing and evaluating the number of rejected power requests from said user equipments.

Method for allocating and controlling downlink power in a telecommunication system

A method and arrangement for testing circuit boards (60) by creating one or several reference patterns to be compared with a test pattern. The arrangement is provided with at least one measuring probe (50), which cooperates with the circuit board (60), for measuring at least one reference signal or test signal on a reference circuit board and a test circuit board (60) respectively. Further, the arrangement is provided with an analyzer (10,30), which cooperates with the measuring probe (50), to pass on the reference signal or the test signal, whereby the analyzer (10,30) first analyzes the reference signal or the test signal at one frequency and then transforms the reference signal or the test signal to a reference pattern and test pattern respectively. Furthermore, the arrangement is provided with at least one memory (20) which cooperates with said analyzer (10,30) to register said reference pattern or test pattern. The memory (20) is provided with two or several reference patterns when testing a circuit board (60).
