Abstract

A method for controlling multiple-input and multiple-output operation in a communication device when the communication device is attached to a battery charger includes determining that a battery level of a communication device is below a first battery level threshold. The method further includes determining that the communication device is attached to a battery char and determining whether to disable multiple-input and multiple-output operation of the communication device while it is attached to the battery charger.

First claim

1 . A method for controlling multiple-input and multiple-output operation of a communication device when the communication device is attached to a battery charger, the method comprising:
determining that a battery level of the communication device is below a first battery level threshold; determining that the communication device is attached to a battery charger; and determining whether to disable multiple-input and multiple-output operation of the communication device while the device is attached to the battery charger.

2 . The method of claim 1 , wherein determining whether to disable the multiple-input and multiple-output operation comprises:
monitoring a type of charger to which the communication device is attached; and disabling the multiple-input and multiple-output operation upon determining that the type of battery charger is a turbo charger.

3 . The method of claim 2 further comprising determining whether to re-enable multiple-input and multiple-output operation of the communication device while it is attached to the turbo charger.

4 . The method of claim 3 , wherein determining whether to re-enable the multiple-input and multiple-output operation comprises:
monitoring the battery level of the communication device; and determining to re-enable the multiple-input and multiple-output operation upon determining that the battery level exceeds a second battery level threshold.

5 . The method of claim 3 , wherein determining whether to re-enable the multiple-input and multiple-output operation comprises:
monitoring a set of parameters that indicate quality of service associated with communicating data to another device; and re-enabling the multiple-input and multiple-output operation of the communication device when at least one parameter in the set of parameters falls below a corresponding threshold.

6 . The method of claim 5 , wherein the set of parameters comprises at least one of bit error rate, packet error rate, packet loss, packet retransmission rate, or retransmission timer results.

7 . The method of claim 6 , wherein re-enabling the multiple-input and multiple-output operation of the communication device comprises partially re-enabling the multiple-input and multiple-output operation.

8 . The method of claim 7 , wherein partially re-enabling the multiple-input and multiple-output operation comprises enabling a transmit path of a first transceiver path while continuing to disable a receive path of the first transceiver path when at least one of the packet retransmission rate or the retransmission timer results falls below the corresponding threshold.

9 . The method of claim 7 , wherein partially re-enabling the multiple-input and multiple-output operation comprises enabling a receive path of a first transceiver path while continuing to disable a transmit path of the first transceiver path when at least one of the bit error rate, the packet error rate, or the packet loss falls below the corresponding threshold.

10 . The method of claim 1 , wherein determining whether to disable the multiple-input and multiple-output operation comprises:
monitoring a charging rate and a discharge rate of a battery of the communication device; and disabling the multiple-input and multiple-output operation upon determining that the discharge rate exceeds the charging rate.

11 . The method of claim 10 further comprising determining whether to re-enable multiple-input and multiple-output operation of the communication device while it is attached to the battery charger.

12 . The method of claim 11 , wherein determining whether to re-enable the multiple-input and multiple-output operation comprises:
monitoring the battery level of the communication device; determining to re-enable the multiple-input and multiple-output operation upon determining that the battery level exceeds a second battery level threshold.

13 . The method of claim 11 , wherein determining whether to re-enable the multiple-input and multiple-output operation comprises:
monitoring a set of parameters that indicate quality of service associated with communicating data to another device; re-enabling the multiple-input and multiple-output operation of the communication device when at least one parameter in the set of parameters falls below a corresponding threshold.

14 . The method of claim 13 , wherein the set of parameters comprises at least one of bit error rate, packet error rate, packet loss, packet retransmission rate, or retransmission timer results.

15 . The method of claim 14 , wherein re-enabling the multiple-input and multiple-output operation of the communication device comprises partially re-enabling the multiple-input and multiple-output operation.

16 . The method of claim 15 , wherein partially re-enabling the multiple-input and multiple-output operation comprises enabling a transmit path of a first transceiver path while continuing to disable a receive path of the first transceiver path when at least one of the packet retransmission rate or the retransmission timer results falls below the corresponding threshold.

17 . The method of claim 15 , wherein partially re-enabling the multiple-input and multiple-output operation comprises enabling a receive path of a first transceiver path while continuing to disable a transmit path of the first transceiver path when at least one of the bit error rate, the packet error rate, or the packet loss falls below the corresponding threshold.

18 . A communication device configured to control multiple-input and multiple-output operation for communicating data, the communication device comprising:
an internal battery configured to power the communication device; a charge adapter configured to charge the internal battery when the communication device is attached to a battery charger; a processor coupled to at least one of the internal battery or the charge adapter, wherein the processor is configured to:
determine that a battery level of the internal battery is below a first battery level threshold;
determine that the communication device is attached to the battery charger; and
determine whether to disable multiple-input and multiple-output operation of the communication device while the device is attached to the battery charger.

19 . The communication device of claim 18 , wherein the processor is configured to determine whether to disable the multiple-input and multiple-output operation by being configured to:
monitor a type of charger to which the communication device is attached; and disable the multiple-input and multiple-output operation upon determining that the type of battery charger is a turbo charger.

20 . The communication device of claim 18 , wherein the processor is configured to determine whether to disable the multiple-input and multiple-output operation by being configured to:
monitor a charging rate and a discharge rate of a battery of the communication device; and disable the multiple-input and multiple-output operation upon determining that the discharge rate exceeds the charging rate.
