Abstract:
In a wireless communication system having a base station and at least one mobile station, said base station operative to establish a communications link with at least one mobile station, said communication link having a plurality of channels, including a low speed channel operative to transmit control commands and traffic data, and one or more of said plurality of channels in combination defining ones of a plurality of data rate modes, a method for managing capacity allocation for a given user comprising the steps of:a. causing a data communications stream transmitted via a forward channel of said communications link to be initiated via said low speed channel; b. gauging a rate of data transmission over said communications link for said given user based on a measure of data in a transmit data buffer for said forward channel; c. for said given user, selecting a data rate mode from said plurality of data rate modes, said selected data rate mode providing sufficient capacity to support said gauged communications link data rate: d. monitoring a receive data buffer associated with a reverse channel for said given user in respect to a degree of fill for said receive buffer; and e. providing a signal to a mobile station of said given user indicative of a reverse channel data rate to be used by said mobile station, said reverse channel data rate being determined as a function of the degree of fill for said receive data buffer.
