Abstract

A method for disabling multiple-input and multiple-output operation in a communication device includes communicating data using multiple-input and multiple-output operation, wherein the data is communicated using multiple transceiver paths. Further, the method includes receiving position sensor input and disabling at least a portion of one or more transceiver paths, of the multiple transceiver paths, based on the position sensor input.

First claim

What is claimed is:

1. A method for disabling multiple-input and multiple-output operation in a communication device, the method comprising:
communicating data using multiple-input and multiple-output operation, wherein the data is communicated using multiple transceiver paths;
receiving position sensor input;
determining receiver sensitivity for the multiple transceiver paths;
disabling at least a portion of one or more transceiver paths, of the multiple transceiver paths, based on the position sensor input and the receiver sensitivity for the multiple transceiver paths.

2. The method of claim 1 , wherein the position sensor input comprises input that indicates a user's hand position on the communication device.

3. The method of claim 1 , wherein the position sensor input comprises input that indicates left-handed or right-handed operation of the communication device.

4. The method of claim 1 , wherein the position sensor input comprises input that indicates a display orientation of the communication device.

5. The method of claim 1 , wherein the position sensor input comprises input that indicates an orientation of the communication device.

6. The method of claim 1 , wherein disabling a portion of one or more transceiver paths is further based on at least one of: receiver sensitivity, cellular performance, and cellular band of operation.

7. The method of claim 1 , wherein each transceiver path is coupled to a different antenna, the method further comprising determining an impedance value for each antenna, wherein the disabling of the at least a portion of the one or more transceiver paths is based on the impedance value determined for each antenna.

8. The method of claim 1 , wherein the multiple transceiver paths comprises a primary transceiver path and a secondary transceiver path having a lower maximum performance rating than the primary transceiver path, wherein at least a portion of the primary transceiver path is disabled based on the position sensor input.

9. The method of claim 1 , wherein the position sensor input comprises at least two of: first input that indicates a user's hand position on the communication device; second input that indicates left-handed or right-handed operation of the communication device; third input that indicates a display orientation of the communication device; or fourth input that indicates an orientation of the communication device, wherein at least a portion of a first transceiver path is disabled based on the position sensor input.

10. The method of claim 9 further comprising:
continuing to monitor the position sensor input;
detecting a change in at least one of the first, second, third, or fourth inputs;
re-enabling the at least a portion of the first transceiver path while disabling at least a portion of a second transceiver path based on the change in the at least one of the first, second, third, or fourth inputs.

11. The method of claim 9 , wherein at least two of the first, second, third, or fourth inputs indicate different transceiver paths to disable, the method further comprising determining receiver sensitivity for the multiple transceiver paths, wherein selecting the at least a portion of the first transceiver path to disable is based on the receiver sensitivity.

12. A communication device configured for disabling multiple-input and multiple-output operation based on position sensor data, the communication device comprising:
a transceiver component having multiple transceiver paths and configured to communicate data using multiple-input and multiple-output operation;
at least one sensor configured to generate position sensor data;
at least one processor coupled to the transceiver component and the at least one sensor, wherein the at least one processor is configured to:
receive the position sensor data;
determine receiver sensitivity for the multiple transceiver paths;
initiate disabling of at least a portion of one or more transceiver paths, of the multiple transceiver paths, based on the position sensor data and the receiver sensitivity for the multiple transceiver paths.

13. The communication device of claim 12 , wherein the at least one sensor comprises at least one of:
a first sensor that generates position sensor data that indicates a user's hand position on the communication device;
a second sensor that generates position sensor data that indicates left-handed or right-handed operation of the communication device;
a third sensor that generates position sensor data that indicates a display orientation of the communication device; or
a fourth sensor that generates position sensor data that indicates an orientation of the communication device.

14. A method for disabling multiple-input and multiple-output operation in a communication device, the method comprising:
communicating data using multiple-input and multiple-output operation, wherein the data is communicated using multiple transceiver paths;
receiving position input relative to the communication device;
determining receiver sensitivity for the multiple transceiver paths;
disabling at least a portion of one or more transceiver paths, of the multiple transceiver paths, based on the position input and the receiver sensitivity for the multiple transceiver paths.

15. The method of claim 14 , wherein the position input indicates a position of a user's hand relative to the communication device.

16. The method of claim 15 , wherein the position input indicates the user's hand is impacting an impedance of an antenna coupled to the disabled transceiver path or transceiver path portion.

17. The method of claim 14 , wherein the position input indicates right-hand or left-hand grip on the communication device.

18. The method of claim 14 , wherein the position input indicates a position of a display of the communication device.

19. The method of claim 14 , wherein the position input indicates a position of the communication device.

20. The method of claim 14 further comprising:
continuing to monitor the position input;
detecting a change in the position input;
changing which one of the one or more transceiver paths is at least in part disabled based on the change in the position input.
