Apparatus and method for selecting processing speed of processor and wireless network

摘要

An apparatus and method for selecting a processor clock speed and a wireless network are disclosed. The method for selecting a processing speed of a processor and/or a wireless network to be connected in a User Equipment (UE) in a wireless communication system includes detecting states of a processor-related queue and a network module-related queue, and selecting a processing speed of the processor-related queue and/or a wireless network to be connected, based on the detected states of the processor-related queue and the network module-related queue and power consumptions of a processor and a network module. The processing speed of the processor-related queue and/or the wireless network to be connected are selected to keep a difference between a length of the processor-related queue and a length of the network module-related queue at a predetermined value and minimize the power consumptions of the processor and the network module.

1. A method for selecting a processing speed of a processor and a wireless network to be connected in a mobile terminal in a wireless communication system, the method comprising:
detecting, by the mobile terminal, states of a processor-related queue and a network module-related queue; and selecting, by the mobile terminal, a processing speed of the processor-related queue and a wireless network to be connected, wherein the processing speed of the processor-related queue is selected based on an energy-delay trade-off parameter V, a power consumption of the processor Pp(s(τ)) at the processing speed s(τ) at time τ, a length of the processor-related queue Qp(τ) at the time τ, a number of cycles per bit λ that the processor can process, and a length of the network module-related queue Qn(τ) at the time τ.
