The present invention discloses a method for resource allocation and rate
control of dedicated channels in a Wideband Code Division Multiple Access
(WCDMA) communication system, the method being characterized by
comprising: a) the step of determining channel states of downlink DCH
channels for non-realtime data services; b) the step of determining
states of the users using said downlink DCH channels; and the step of
correlating the channel states determined in step a) with the user states
determined in step b), and dynamically allocating the DCH channels with
certain rates to the users in the different User states according to a
wireless measurement result measured by a current transmission channel
and based on the priority and fairness requirements. According to the
present invention, the method effectively realizes the bandwidth resource
allocation and rate control, improves the radio resource availability and
provides users, to the maximum extent, with a data service bandwidth as
high as possible.
