Abstract

Device, system, and method of power saving in wireless communication. In some demonstrative embodiments a method may include, for example, receiving at a base station at least one uplink power saving message from at least one mobile communication device, respectively, wherein the power saving message includes battery level information and an indication of at least one power saving mechanism; and based on the battery level information and the indication, applying a selected power saving mechanism to communications between the base station and the at least one mobile communication device. Other embodiments are described and claimed

Claims

1. A method comprising:

receiving at a base station at least one uplink power saving message from at least one mobile communication device, respectively, wherein said power saving message includes battery level information and an indication of at least one power saving mechanism; and

based on said battery level information and said indication, applying a selected power saving mechanism to communications between said base station and said at least one mobile communication device.

2. The method of claim 1, wherein applying the selected power saving mechanism comprises adjusting one or more communication-configuration parameters between said base station and said at least one mobile communication device.

3. The method of claim 2, wherein adjusting said communication-configuration parameters comprises transmitting a downlink message from said base station to said at least one mobile communication device, wherein said downlink message includes adjustment information corresponding to said communication-configuration parameters.

4. The method of claim 2, wherein adjusting said communication configuration parameters comprises adjusting at least one of a priority scheme applied to said communications, a bandwidth aggregation for non-real-time traffic mechanism applied to said communications, a bandwidth aggregation for real-time traffic mechanism applied to said communications, a connection-identification aggregation mechanism applied to said communications, a multiple-input-multiple output scheme applied to said communications, a modulation order applied to said communications, a quality-of-service of said communications, and a bandwidth allocated to said communications.

5. The method of claim 2, wherein adjusting said communication configuration parameters comprises at least one of increasing a priority of said mobile communication device, increasing a burst allocated to said mobile communication device, aggregating transmission frames to said mobile communication device, aggregating connection-identification bursts allocated to said mobile communication device, decrease a number of reception antennas implemented at said mobile communication device, decreasing a modulation order of a communication with said mobile communication device, decreasing a quality-of-service of the communication with said mobile communication device, and increasing a bandwidth allocated to the communication with said mobile communication device.

6. The method of claim 1 comprising transmitting said uplink power saving message from said mobile communication device if a battery power level of said mobile communication device is lower than a battery power level threshold.

7. The method of claim 1, wherein said uplink power saving message comprises one or more threshold values corresponding to said power saving mechanism.

8. The method of claim 7, wherein said one or more threshold values comprise at least one of a delay threshold value and a jitter threshold value.

9. A base station capable of receiving from at least one mobile communication device at least one uplink power saving message including battery level information and an indication of at least one power saving mechanism;

and, based on said battery level information and said indication, applying a selected power saving mechanism to communications between said base station and said mobile communication device.

10. The base station of claim 9, wherein said base station is capable of adjusting one or more communication configuration parameters between said base station and said at least one mobile communication device.

11. The base station of claim 10, wherein base station is capable of transmitting a downlink message to said at least one mobile communication device, wherein said downlink message includes an indication of said communication configuration parameters.

12. The base station of claim 10, wherein said base station is capable of adjusting at least one of a priority scheme applied to said communications, a bandwidth aggregation for non-real-time traffic mechanism applied to said communications, a bandwidth aggregation for real-time traffic mechanism applied to said communications, a connection-identification aggregation mechanism applied to said communications, a multiple-input-multiple output scheme applied to said communications, a modulation order of said communications, a quality-of-service of said communications, and a bandwidth allocated to said communications.

13. The base station of claim 9, wherein said battery level information indicates a battery power level of said mobile communication device is lower than a battery power level threshold.

14. The base station of claim 9, wherein said uplink power saving message comprises one or more threshold values corresponding to said power saving mechanism.

15. The base station of claim 14, wherein said one or more threshold values comprise at least one of a delay threshold value and a jitter threshold value.
