Abstract:
1. A method of optimizing scheduling in a communications network of CDMA type comprising one or more base stations and one or more mobile users, the signals exchanged being composed of one or of several frames consisting of slots s, comprising the following steps: a) positioning an analysis device comprising one or more reception pathways suitable for detecting the base stations received at a measurement point by means of multisensor synchronization, b) for each detected base station, estimating the propagation channel, h(0, s), . . . , h(L−1, s), between the measurement point and the device, with L the length of the propagation channel, c) on the basis of the power of the paths returned by the channel estimation, estimating the received powers Pi for all the detected base stations, d) determining the base station or stations of highest levels which define a group of active stations {Gsa}, e) on the basis of the results obtained in steps a) to d), estimating for each base station of the group of active stations {Gsa}, the reception filter g (0, s, a) implemented by a mobile situated at the measurement point for the reception of the station considered, f) estimating, for each slot s and each antenna configuration a of the mobile, the ratio E g) determining the services that can be ensured at the measurement point and compare the value of the interference factor IF obtained in step f) with the threshold values dependent on each type of service.
