Abstract
By controlling reverse rates among mobile stations to reduce reverse-link interference, reverse-link throughput can be increased.
Claims52
A method comprising
- determining a forward-link data rate at a mobile device at which the mobile device desires to receive its forward-link data packets from a base station,
- transmitting information conveying the forward-link data rate from the mobile station to the base station,
- determining a maximum reverse data rate at the base station based on the forward-link data rate,
- transmitting information conveying the maximum reverse data rate from the base station to the mobile device,
- determining at the mobile station its operational reverse rate between zero and the maximum reverse data rate, and
- transmitting data packets by the mobile station at the determined operational reverse rate.
3 more elements
A method comprising
- determining a maximum reverse data rate based on an estimated amount of interference a mobile device is causing to one or more sectors other than the sectors serving the mobile device,
- transmitting reverse rate information conveying the maximum reverse data rate between a base station and the mobile device, the base station including one or more sectors, and
- transmitting sector rate control information from the one or more sectors to all mobile devices in that respective sector,
- determining an operational reverse rate at the mobile station between zero and the maximum rate based on the sector rate control information, and
- transmitting data packets by the mobile station at the determined operational reverse rate without further consulting the base station.
2 more elements
A method comprising,
- determining a forward-link data rate at a mobile device at which the mobile device desires to receive its forward-link data packets from a base station,
- determining a requested reverse data rate at the mobile station at which the mobile device desires to transmit its reverse-link data packets to the base station,
- transmitting information conveying the forward-link data rate and the requested reverse data rate from the mobile station to the base station,
- determining at the base station a reverse data rate between zero and the requested reverse data rate based on the forward-link data rate information,
- transmitting information conveying the determined reverse data rate from the base station to the mobile device, and
- transmitting data packets by the mobile station at the determined reverse rate.
3 more elements
A method comprising
- determining a forward-link data rate at a mobile device at which the mobile device desires to receive its forward-link data packets from a base station,
- transmitting information conveying the desired forward-link data rate from the mobile station to the base station,
- determining at the base station a reverse data rate based on the desired forward-link data rate information,
- transmitting information conveying the determined reverse data rate from the base station to the mobile device, and
- transmitting data packets by the mobile station at the determined rate.
