Abstract
A system and method for controlling a data rate of a next reverse packet data frame in a mobile communication system for transmitting a reverse packet data frame from a mobile station to a base station over a reverse packet data channel at a data rate selected from a plurality of data rates. The mobile station receives reverse control information for the data rate of the reverse packet data frame, and transmits the next reverse packet data frame at a data rate that is determined according to the reverse control information.
Claims34
A method for controlling a data rate of a reverse packet data frame in a mobile station of mobile communication system, comprising the steps of:
- receiving a reverse control information for a data rate of a next transmission reverse packet data frame;
- determining the data rate of the next transmission reverse packet data frame by the reverse control information and a data rate of a previously transmitted reverse packet data frame determined by a predetermined rate control delay;
- and
- transmitting the reverse packet data frame at the determined data rate.
A method for controlling a data rate of a reverse packet data frame in a mobile station of mobile communication system, comprising the steps of:
- receiving an acknowledgement from the base station, indicating whether reception of the reverse packet data frame is successful;
- if the reception of the reverse packet data frame is successful, receiving a reverse control information for a data rate of a next transmission reverse packet data frame;
- determining a data rate of the next transmission reverse packet data frame based on a predetermined rate control delay;
- and
- transmitting the reverse packet data frame at the determined data rate.
An apparatus for controlling a data rate of a reverse packet data frame in a mobile station of a mobile communication system, comprising:
- a receiver for receiving reverse control information for a data rate of a next transmission reverse packet data frame;
- a controller for determining the data rate of the next transmission reverse packet data frame by the reverse control information and a data rate of previously transmitted reverse packet data frame determined by a predetermined rate control delay;
- and
- a transmitter for transmitting the next transmission reverse packet data frame to the base station according to the determined data rate.
A method for controlling a data rate of a reverse packet data frame in a mobile station of mobile communication system, comprising the steps of:
- receiving a rate control command from the base station over a forward rate control channel;
- determining a data rate of a next transmission packet data frame by the received rate control command and a data rate of a previously transmitted packet data frame corresponding to a same ACID (ARQ (Automatic Repeat reQuest) Channel Indicator);
- and
- transmitting a packet data frame over the reverse packet data channel at the determined data rate.
A mobile station apparatus for controlling a data rate of a reverse packet data frame in a mobile station of mobile communication system, comprising:
- a forward rate control channel (F-RCCH) receiver for receiving a rate control command from the base station over a forward rate control channel;
- a rate controller for determining a data rate of a next transmission packet data frame by the received rate control command and a data rate of a previously transmitted packet data frame corresponding to a same ACID (ARQ (Automatic Repeat reQuest) Channel Indicator);
- and
- a reverse packet data channel (R-PDCH)transmitter for transmitting a packet data frame over the reverse packet data channel at the data rate determined by the rate controller.
33 The mobile station apparatus of claim 32, wherein the rate controller determines whether the received rate control command indicates one of an increase, a decrease, and a hold of a data rate.
