Embodiment Construction

[0014] A further understanding of the exemplary embodiments may be obtained with reference to the following description and to the drawings, wherein like elements are designated by the same reference numerals. The exemplary embodiments describe an apparatus, system, and method for managing transmit power of mobile devices in a wireless communication network. In an exemplary embodiment, mobile devices will be described as user equipment ("UE") and base stations will be described as evolved Node B ("eNB") base stations generally considered to be base stations associated with an LTE network. However, those skilled in the art will understand that UEs, base stations or access points operating according to other network standards can also implement these exemplary embodiments according to the functions and principles described herein.

[0015] figure 1 An exemplary apparatus 100 is shown for peak power management at a mobile device in a wireless network according to various exempla...

Abstract

An apparatus, system and method for determining whether a battery alarm of a UE is asserted, reducing a transmission duty cycle of the UE to zero for a first predetermined time period when the battery alarm is asserted, determining whether the battery alarm has been de-asserted after the first predetermined time period and when the battery alarm has not been de-asserted, increasing the transmission duty cycle to a first threshold level for a second predetermined time period, wherein the first threshold level is less than a full transmission duty cycle of the UE. When the battery alarm has been de-asserted, increasing the transmission duty cycle to a second threshold level for a third predetermined time period, wherein the second threshold level is less than the full transmission duty cycle of the UE, and wherein the second threshold level is greater than the first threshold level.

Description

[0001] PRIORITY INFORMATION / INCORPORATION BY REFERENCE [0002] This patent application claims priority to the following U.S. Provisional Applications: U.S. Provisional Application 62 / 161,217, filed May 13, 2015, entitled "Apparatus, Systems and Methods For Power Management in Mobile Devices" and filed May 18, 2015 U.S. Provisional Application 62 / 163,138, titled "Apparatus, Systems and Methods For Power Management in Mobile Devices," filed on 11 December 2011, both of which are incorporated herein by reference in their entirety. Background technique [0003] In wireless telecommunication networks, Long Term Evolution or "LTE" is defined as a standard for wireless communication of high-speed data for mobile phones and data terminals. The LTE standard was developed by the Third Generation Partnership Project ("3GPP") and the Institute of Electrical and Electronics Engineers ("IEEE"). An exemplary LTE access network is a wireless network of base stations or evolved Node Bs ("e...
