Abstract

A method is provided for controlling operation of a wireless device, including: receiving an initial incoming signal from a remote device in a first operational mode, the initial incoming signal including information related to an initial remaining battery power in the remote device; determining that a second operational mode will be a first possible mode if the initial remaining battery power in the remote device is within a first power range; determining that the second operational mode will be a second possible mode if the initial remaining battery power in the remote device is within a second power range; and transmitting instructions to the remote device in the first operational mode to transmit and receive in the second operational mode.

Claims

1. A method for controlling operation of a wireless device, including:

receiving an initial incoming signal from a remote device in a first operational mode, the initial incoming signal including information related to an initial remaining battery power in the remote device;

determining that a second operational mode will be a first possible mode if the initial remaining battery power in the remote device is within a first power range;

determining that the second operational mode will be a second possible mode if the initial remaining battery power in the remote device is within a second power range; and

transmitting instructions to the remote device in the first operational mode to transmit and receive in the second operational mode.

2. The method for controlling the operation of the wireless device, as recited in claim 1, wherein the first possible mode is a full duplex mode and the second possible mode is a half-duplex mode.

3. The method for controlling the operation of the wireless device, as recited in claim 2, wherein the first operational mode is the half-duplex mode.

4. The method for controlling the operation of the wireless device, as recited in claim 1, further including:

receiving an operational incoming signal from a remote device in the second operational mode after transmitting the instructions to the remote device, the operational incoming signal including a request for assignment of a requested mode, and information related to a revised remaining battery power in the remote device;

determining whether the requested mode is an appropriate mode by considering the revised remaining battery power in the remote device;

setting a third operational mode to be the requested mode if the requested mode is appropriate;

setting the third operational mode to be an alternate mode if the requested mode is not appropriate; and

transmitting instructions to the remote device in the second operational mode to transmit and receive in the third operational mode.

5. The method for controlling the operation of the wireless device, as recited in claim 4, wherein the first possible mode is a full duplex mode and the second possible mode is a half-duplex mode.

6. The method for controlling the operation of the wireless device, as recited in claim 5, wherein the first operational mode is the half-duplex mode.

7. The method for controlling the operation of the wireless device, as recited in claim 4, wherein the requested mode is one of a full duplex mode and a half-duplex mode.

8. The method for controlling the operation of the wireless device, as recited in claim 4, wherein the requested mode is determined to be an appropriate mode if the revised remaining battery power in the remote device is above a power threshold.

9. A method for controlling the operation of the wireless device, including:

receiving an initial incoming signal from a remote device in a first operational mode, the initial incoming signal including information related to an initial remaining battery power in the remote device;

determining that a second operational mode will be a first possible mode if the initial remaining battery power in the remote device is within a first range;

determining that the second operational mode will be a second possible mode if the initial remaining battery power in the remote device is within a second range;

transmitting instructions to the remote device in the first operational mode to transmit and receive in the second operational mode

11. The method for controlling the operation of a remote device in a wireless network, as recited in claim 9, wherein the first possible mode is one of a full duplex mode and a half-duplex mode, and the second possible mode is another of the full duplex mode and the half-duplex mode.

12. The method for controlling the operation of the wireless device, as recited in claim 9, further including:

receiving an request incoming signal from a remote device in the third operational mode after transmitting the instructions to the remote device to transmit in the third operational mode, the request incoming signal including a request for assignment of a requested mode, and information related to a current remaining battery power in the remote device;

determining whether the requested mode is an appropriate mode by considering the current remaining battery power in the remote device;

setting a third operational mode to be the requested mode if the requested mode is appropriate;

setting the third operational mode to be an alternate mode if the requested mode is not appropriate; and
