Distributed multi-radio transmission diversity

1. A method of communicating using multi-radio transmission diversity, comprising the steps of:

receiving, at a base station, downlink measurement reports from a mobile station regarding each of a plurality of downlinks between the mobile station and a plurality of base stations;

determining, at the base station, which of the base stations will transmit a selected transmission to the mobile station responsive to the received downlink measurement reports; and

receiving an acknowledgement from the mobile station indicating the mobile station received the selected transmission.

2. The method of claim 1 , comprising

receiving the downlink measurement reports at each of the plurality of base stations; and

determining which of the base stations will transmit the selected transmission at each of the base stations, independent of the other base stations.

3. The method of claim 1 , comprising

receiving the downlink measurements from each of a plurality of mobile stations, respectively; and

determining, at each of the base stations, which of the base stations will transmit a selected transmission to each of the mobile stations, respectively.

4. The method of claim 1 , comprising

determining whether there is an error associated with the received downlink measurements at each of the base stations; and

at least temporarily removing a base station from an active set for the mobile station responsive to determining that there is an error.

5. The method of claim 1 , comprising

receiving the acknowledgement at each of the plurality of base stations subsequent to the mobile station receiving the selected transmission from the determined base station.

6. The method of claim 1 , comprising

removing data corresponding to the selected transmission from a buffer at any one of the base stations that successfully receives the acknowledgement.

7. The method of claim 1 , comprising

determining whether there is an error associated with the received acknowledgement; and

at least temporarily removing a base station from an active set for the mobile station responsive to determining that there is an error.

8. The method of claim 1 , comprising

repeatedly receiving the acknowledgement at least until a next subsequent transmission is scheduled for the mobile station.

9. The method of claim 8 , comprising

receiving the acknowledgement with the received downlink measurement reports.

10. A method of communicating using multi-radio transmission diversity, comprising the steps of:

transmitting a collective downlink measurement report regarding each of a plurality of downlink measurements from a mobile station to each of a plurality of base stations;

receiving a transmission from at least one of the plurality of base stations; and

transmitting an acknowledgement of the received transmission to each of the plurality of base stations.

11. The method of claim 10 , comprising

repeatedly determining a quality of the downlink channel of each of the plurality of base stations; and

transmitting each determined quality as the collective downlink measurement report.

12. The method of claim 10 , comprising

repeatedly transmitting the acknowledgement to each of the plurality of base stations at least until receiving a next transmission from at least one of the base stations.

13. The method of claim 12 , comprising

transmitting the acknowledgement with the transmitted collective downlink measurement report.

14. The method of claim 10 , wherein a number of downlinks in the collective downlink measurement report equals a number of base stations in the plurality of base stations.
