Abstract

A controller (101, 103) provides forward links (109) and reverse links (111a, 111b, 111c) for use in communication with communication devices (107). The controller (101, 103) has receivers including a first receiver and a second receiver, and transmitters. A processor of the controller (101) assigns one of transmitters as a forward link (109) and the first receiver (111a) as a reverse link, together forming at least one duplex link. Also, the processor assigns the second receiver as another reverse link (111b), independent of an assignment of a transmitter, to form a simplex reverse link.

Claims

1. A controller providing forward links and reverse links for use in communication with communication devices, comprising:

a plurality of receivers including at least one first receiver and at least one second receiver, and a plurality of transmitters including at least one transmitter;

a processor, the processing being configured to facilitate;

first assigning the at least one transmitter as at least one forward link and the at least one first receiver as at least one first reverse link, together forming at least one duplex link; and

second assigning the at least one second receiver as at least one second reverse link, independent of an assignment of a transmitter, to form at least one simplex reverse link.

2. The controller of claim 1, wherein the processor is further configured for combining signals received from a communication device on the at least one first receiver of the at least one duplex link and the at least one second receiver of the at least one simplex reverse link.

3. The controller of claim 1, wherein the processor is further configured for determining the at least one second receiver of the plurality of receivers to be assigned as the at least one second reverse link, wherein the second assigning is performed responsive to the determining.

4. The controller of claim 3, wherein the determining includes performing a determination of a quality of a signal received from a communication device, judging whether the quality is acceptable, and performing the second assigning if the quality is acceptable.

5. The controller of claim 4, further comprising a scanner to measure the quality, where the communication device is not in an active set sector.

6. The controller of claim 4, wherein the quality is determined from information representative of a plurality of communication devices retrieved from storage.

7. The controller of claim 3, wherein the plurality of receivers and the plurality of transmitters form a plurality of sectors;

wherein the at least one duplex link is utilized in communication with a communication device in at least one of the plurality of sectors; and

wherein the determining includes judging one of the sectors from which the at least one second receiver is to be assigned.

8. The controller of claim 3, wherein the determining includes performing a determination of a communication device with a signal of acceptable quality in a local area, and the at least one second reverse link is further assigned to the at least one communication device.

9. The controller of claim 1, wherein the processor is further configured to facilitate determining at least one other receiver to be assigned to form at least a second simplex reverse link, wherein the at least one other receiver is determined to be on a base station, and to facilitate transmitting a reverse link request to the base station.

10. The controller of claim 1, wherein the assigning is responsive to a receipt of a reverse link request from a base station.

11. The controller of claim 1, wherein the processor is further configured to facilitate transmitting a notification about an availability of the at least one second reverse link to a base station.

12. The controller of claim 1, the plurality of transmitters including at least one second transmitter, the at least one second transmitter being assigned as at least one second forward link;

wherein the processor is further configured to facilitate transmitting a notification about an availability of the at least one second forward link and the at least one second reverse link.

13. The controller of claim 1, wherein the at least one duplex link is utilized in communication with a communication device, wherein the processor is further configured to facilitate continuing to communicate with the communication device utilizing the at least one duplex link and the at least one simplex reverse link.

14. The controller of claim 1, wherein the processor is further configured to facilitate, responsive to a handoff, forming at least a second duplex link utilizing the at least one second receiver.

15. A method of providing forward links and reverse links for use in communication with a communication device, comprising:

first assigning at least one transmitter of a plurality of transmitters on at least one base station as at least one forward link, and at least one first receiver of a plurality of receivers on the at least one base station as at least one first reverse link, together forming at least one duplex link in communication with a communication device;

determining at least one second receiver of the plurality of receivers to be assigned as at least one second reverse link, including performing a determination of a quality of a signal received from the communication device, and judging whether the quality is acceptable; and

second assigning, if the quality is acceptable, the at least one second receiver 13 as the at least one second reverse link, independent of an assignment of a transmitter, to form at least one simplex reverse link in communication with the communication device.

16. The method of claim 15, wherein the determining further includes retrieving information representative of the quality from storage, where the communication device is in communication with at least one receiver that is not in an active set sector.

17. The method of claim 15, wherein the determining further comprises scanning the communication device to measure the quality, where the communication device is in communication with at least one receiver that is not in an active set sector.

18. The method of claim 15, further comprising forming at least one second duplex link to communicate with the communication device, the second duplex link utilizing the at least one simplex reverse link.

19. The method of claim 15, further comprising signaling at least a second base station to indicate an availability of the at least one simplex reverse link.

20. The method of claim 15, further comprising signaling at least a second base station to request an assignment of at least a second simplex reverse link on the second base station.

21. A computer-readable medium comprising instructions being executed by a computer, the instructions including a computer-implemented method for managing a communication environment for communicating with communication devices utilizing duplex links, where a duplex link includes a forward link corresponding to a transmitter and a reverse link corresponding to a receiver, the instructions for implementing the steps of:

(A) first assigning at least one receiver of a plurality of receivers as at least one simplex reverse link;

(B) second assigning the at least one simplex reverse link to a communication device;

(C) transmitting a communication to the communication device on a duplex link; and

(D) receiving a signal from the communication device on the at least one simplex reverse link.

22. The medium of claim 21, wherein the signal is further received on the at least one simplex reverse link and the reverse link of the duplex link, further comprising instructions for implementing the step of combining the signals received from the communication device on the at least one simplex reverse link and the reverse link of the duplex link.

23. The medium of claim 21, further comprising instructions for implementing a step of providing the duplex link, including assigning at least one transmitter of a plurality of transmitters as at least one forward link, and assigning at least one other receiver of the plurality of receivers as a duplex reverse link.

24. The medium of claim 21, further comprising instructions for implementing a step of determining a quality of a signal from the communication device, wherein the second assigning is responsive to the quality.

25. The medium of claim 21, further comprising instructions for implementing a step of adding, responsive to a handoff of the communication device, a forward link to the at least one simplex reverse link, to form a second duplex link to the communication device.
