Abstract

A method of managing antenna usage within a communication device can include determining selected transceivers of a plurality of transceivers requiring a connection with an antenna (410) and identifying diversity requirements for the selected transceivers (420). A plurality of antennas can be allocated among the selected transceivers according to the diversity requirements (425, 430).

Claims

1. Within a communication device, a method of managing antenna usage comprising:

determining selected transceivers of a plurality of transceivers requiring a connection with an antenna;

identifying diversity requirements for the selected transceivers; and

allocating a plurality of antennas among the selected transceivers according to the diversity requirements.

2. The method of claim 1, further comprising connecting allocated antennas with the selected transceivers.

3. The method of claim 1, wherein allocating the plurality of antennas further comprises assigning at least two antennas to each selected transceiver having a diversity requirement.

4. The method of claim 1, wherein allocating the plurality of antennas further comprises assigning at least one antenna to each transceiver requiring an antenna.

5. The method of claim 1, wherein allocating the plurality of antennas further comprises assigning antennas to selected transceivers according to a priority associated with each transceiver.

6. The method of claim 5, further comprising varying the priority for at least one transceiver according to an operating state of the communication device.

7. The method of claim 1, further comprising:

disabling one of the plurality of transceivers;

selecting an alternate transceiver to be used in lieu of the disabled transceiver; and

disconnecting at least one antenna from the disabled transceiver and connecting the at least one antenna to the alternate transceiver.

8. The method of claim 1, further comprising selectively connecting baseband modules with different ones of the plurality of transceivers according to the diversity requirements.

9. A communication device comprising:

a plurality of antennas;

a plurality of transceivers; and

a controller determining an allocation of the plurality of antennas among different ones of the plurality of transceivers according, at least in part, to diversity requirements of the plurality of transceivers.

10. The communication device of claim 9, wherein the controller connects the plurality of antennas with the plurality of transceivers according to the allocation.

11. The communication device of claim 9, wherein the controller connects unallocated antennas to transceivers of the plurality of transceivers that do not have a diversity requirement.

12. The communication device of claim 9, wherein the controller allocates at least one antenna to each transceiver requiring an antenna.

13. The communication device of claim 9, wherein the controller allocates at least two antennas to each transceiver requiring an antenna and having a diversity requirement.

14. The communication device of claim 9, wherein the controller further determines the allocation according to a priority associated with each of the plurality of transceivers.

15. The communication device of claim 14, wherein the controller dynamically varies the priority of at least one transceiver according to an operating state of the communication device.

16. The communication device of claim 9, further comprising:

a plurality of baseband modules; and

a baseband controller connecting selected baseband modules with selected ones of the plurality of transceivers.

17. The communication device of claim 16, wherein the baseband controller connects a selected baseband module with at least two of the plurality of transceivers, wherein each of the at least two transceivers is connected by the controller with at least one antenna of the plurality of antennas.

18. The communication device of claim 17, wherein the baseband controller connects the selected baseband module with a transmitter channel and a receiver channel of a first of the at least two transceivers and connects the selected baseband module with the receiver channel of the second of the at least two transceivers.

19. A communication device comprising:

a plurality of antennas;

a plurality of transceivers;

a plurality of baseband modules;

a diversity controller selectively connecting different ones of the plurality of transceivers with different ones of the plurality of antennas according, at least in part, to diversity requirements of the plurality of transceivers; and

a baseband controller connecting selected baseband modules with selected ones of the plurality of transceivers.

20. The communication device of claim 19, wherein the baseband controller connects one of the plurality of baseband modules to at least two transceivers according to the diversity requirements.
