Abstract
A wireless communications network includes a base station to communicate with plural mobile stations over a wireless link. A broadcast message is sent to the plural mobile stations, with the broadcast message containing an indication for indicating to the plural mobile stations that the mobile stations are to change data rates for transmissions over a reverse wireless link.
Claims9
A method performed by a mobile station, comprising:
- receiving a broadcast message from a base station transmitted to a plurality of mobile stations, the message including an indication that the plurality of mobile stations are to adjust respective maximum autonomous data rates by an incrementing or decrementing step;
- and
- adjusting a maximum autonomous data rate specified for the mobile station by the incrementing or decrementing step, wherein the maximum autonomous data rate specifies the maximum allowable transmission rate during an autonomous mode operation by the mobile station on a reverse packet data channel.
A mobile station comprising:
- an interface for receiving a broadcast message from a base station transmitted to a plurality of mobile stations, the message including an indication that the plurality of mobile stations are to adjust respective maximum autonomous data rates by an incrementing or decrementing step;
- and
- a controller for adjusting a maximum autonomous data rate specified for the mobile station by the incrementing or decrementing step, wherein the maximum autonomous data rate specifies the maximum allowable transmission rate during an autonomous mode operation by the mobile station on a reverse packet data channel.
A method for use in a wireless communications network, comprising:
- communicating data to a plurality of mobile stations over a wireless link;
- and
- sending a broadcast message to the plurality of mobile stations, wherein the broadcast message includes an indicator that can be set to a first value or a second value;
- wherein, when the indicator is set to a first value, the broadcast message indicates to a particular mobile station identified by the first value that this particular mobile station is to change to a data rate specified in the broadcast message, and wherein, when the indicator is set to a second value, the broadcast message indicates to the plurality of mobile stations that the plurality of mobile stations are to change respective data rates to be less than or equal to an autonomous data rate of each of the plurality of mobile stations.
