Bandwidth is allocated in a radio packet data system by sending achievable data rate estimate information from an access terminal to an access network. The achievable data rate estimate information is associated with scenarios corresponding to state combinations of a plurality of transmitters in the access network in which each transmitter is in either a serving, active, or idle state and one or more of the plurality of transmitters is in the idle state in one or more of the scenarios.
