Abstract

Systems, methods, apparatuses, and computer-readable storage media for managing power consumption of a mobile device are disclosed. The systems, method, apparatus, and computer-readable storage medium may cause the base station to identify an energy metric associated with a mobile device, and to configure the transmission between the base station and the mobile device based at least in part on the energy metric. The configuration of the transmission may reduce the power consumption of the mobile device for processing the transmission.

First claim

What is claimed is:

1. A method comprising:
identifying, at a base station, an energy metric associated with a mobile device, wherein the energy metric includes information that indicates an energy consumption by the mobile device to process a transmission of data;
identifying one or more modulation and coding schemes (MCSs) available for configuring the transmission;
evaluating the one or more available MCSs to identify an MCS that reduces energy consumption by the mobile device to process the transmission based at least in part on the energy metric; and
configuring, at the base station, a transmission between the base station and the mobile device based at least in part on the energy metric and the MCS that reduces energy consumption by the mobile device for the transmission.

2. The method of claim 1 , wherein the energy metric associated with the mobile device comprises one or more parameters associated with configuring transmissions between the base station and the mobile device, wherein the one or more parameters include at least one parameter that affects the energy consumption by the mobile device to process the transmissions between the base station and the mobile device.

3. The method of claim 1 , further comprising identifying a capability of the mobile device, wherein the transmission is configured based, at least in part, on the capability of the mobile device.

4. The method of claim 3 , further comprising receiving a message from the mobile device, wherein the message comprises information that indicates the capability of the mobile device.

5. The method of claim 4 , wherein the capability of the mobile device comprises at least one of one or more transmission modes (TMs) supported by the mobile device, one or more MCSs supported by the mobile device, one or more carrier aggregation (CA) schemes supported by the mobile device, bandwidth capabilities of the mobile device, a frame structure supported by the mobile device, a category of the mobile device, interference management techniques supported by the device, one or more duplex modes supported by the mobile device, or a combination thereof.

6. The method of claim 1 , wherein the energy metric is determined based at least in part on information stored at a database accessible to the base station.

7. The method of claim 1 , further comprising periodically determining whether to modify a configuration of a subsequent transmission between the base station and the mobile device based at least in part on the energy metric.

8. The method of claim 1 , further comprising determining an available network resource, wherein the configuration of the transmission is determined based at least in part on the available network resource.

9. The method of claim 1 , further comprising:
identifying one or more semi-dynamic parameters and one or more dynamic parameters, wherein the one or more semi-dynamic parameters correspond to parameters that are configured independent of scheduling the transmission, and wherein the one or more dynamic parameters correspond to parameters that are configured during scheduling of the transmission; and
determining the configuration of the transmission based on the one or more semi-dynamic parameters, the one or more dynamic parameters, and the energy metric.

10. The method of claim 9 , wherein the method includes:
determining whether the one or more semi-dynamic parameters impose constraints on the one or more dynamic parameters; and
determining the one or more dynamic parameters for configuring the transmission based on whether the one or more semi-dynamic parameters impose constraints on the one or more dynamic parameters.

11. The method of claim 9 , wherein the one or more dynamic parameters include an MCS to be used for the transmission, a resource block assignment to be used for the transmission, a transport block size to be used for the transmission, a coding rate to be used for the transmission, availability of network resources, channel information, or a combination thereof, and wherein the semi-dynamic parameters include a transmission mode, a quality of service associated with the transmission, a capability of the mobile device, cell loading information, service information associated with the mobile device, a target signal to noise plus interference (SINR) for the transmission, a threshold block level error rate (BLER) for the transmission, or a combination thereof.

12. The method of claim 1 , further comprising determining a quality of service (QoS) associated with the transmission between the base station and the mobile device, wherein the transmission between the base station and the mobile device is configured based, at least in part, on the determined QoS.

13. The method of claim 1 , further comprising:
determining a first energy consumption by the mobile device to process the transmission between the base station and the mobile device based at least in part on the energy metric;
determining a second energy consumption by the mobile device to process the transmission between the base station and the mobile device independent of the energy metric;
determining a difference between the first energy consumption and the second energy consumption; and
determining whether the difference between the first energy consumption and the second energy consumption satisfies a threshold.

14. The method of claim 13 , wherein the transmission between the base station and the mobile device is configured based at least in part on the energy metric when the difference between the first energy consumption and the second energy consumption satisfies the threshold.

15. The method of claim 13 , wherein the transmission between the base station and the mobile device is configured independent of the energy metric when the difference between the first energy consumption and the second energy consumption does not satisfy the threshold.

16. The method of claim 1 , wherein configuring the transmission between the base station and the mobile device further comprises scheduling the transmission using a number of resource blocks, wherein the number of resource blocks scheduled for the transmission is determined based at least in part on the energy metric.
