Method Of Optimizing Scheduling In A Communications System Of Cdma Type

摘要

Method of optimizing scheduling in a communications network of CDMA type comprising at least the following steps:;detect the base stations received at a measurement point by means of multisensor synchronization, and for each of them estimate the propagation channel, h(0, s), . . . , h(L−1, s), estimate the received powers Pi,;determine the base station or stations of highest levels which define a group of active stations {Gsa},;on the basis of the results obtained in the preceding steps, estimate 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,;estimate, for each slot s and each antenna configuration a of the mobile, the ratio E_s/I₀, on the basis of the estimates of the propagation channel, and deduce therefrom the interference factor IF associated with the mobile placed at the measurement point.
