Abstract
Methods, systems, and devices for wireless communication are described that provide for power management of wireless devices by selecting a radio access technology (RAT) from multiple RATs for communication. A wireless device may determine power usage for a data transmission for each of multiple RATs and transmit the data based at least in part on a the determined power usages. The power usage for different RATs may be determined based at least in part on channel conditions, average power, RAT throughput, or variance, among other factors.
Claims20
A method for wireless communication, comprising:
- determining a first power usage of a first radio access technology (RAT) for transmission of a data packet based at least in part on a first estimated time to transmit a fixed amount of data associated with the data packet using the first RAT;
- determining a second power usage of a second RAT for transmission of the data packet based at least in part on a second estimated time to transmit the fixed amount of data associated with the data packet using the second RAT;
- and
- transmitting, based at least in part on the determined first power usage and the determined second power usage, the data packet according to one from the group consisting of the first RAT and the second RAT.
A communications device for wireless communication, comprising:
- a first transceiver associated with a first RAT;
- a second transceiver associated with a second RAT;
- and
- a power usage manager to determine a first power usage of a first radio access technology (RAT) for transmission of a data packet based at least in part on a first estimated time to transmit a fixed amount of data associated with the data packet using the first RAT, and determine a second power usage of a second RAT for transmission of the data packet based at least in part on a second estimated time to transmit the fixed amount of data associated with the data packet using the second RAT;
- and
- wherein the data packet is transmitted by one of the first transceiver or the second transceiver based at least in part on the determined first power usage and the determined second power usage, the data packet transmitted according to one from the group consisting of the first RAT and the second RAT.
A non-transitory computer readable medium storing code for wireless communication, the code comprising instructions executable by a processor to:
- determine a first power usage of a first radio access technology (RAT) for transmission of a data packet based at least in part on a first estimated time to transmit a fixed amount of data associated with the data packet using the first RAT;
- determine a second power usage of a second RAT for transmission of the data packet based at least in part on a second estimated time to transmit the fixed amount of data associated with the data packet using the second RAT;
- and
- transmit, based at least in part on the determined first power usage and the determined second power usage, the data packet according to one from the group consisting of the first RAT and the second RAT.
