Patent number: 10091793Abstract: A UE controls in-device coexistence (IDC) indication message generation to mitigate potential throughput impact on UE to maintain UE performance as much as possible. Under the proposed method, FDM-based solution is always preferred by the UE. Based on the IDC indication message generated by the UE, a network applies an IDC interference mitigation solution that prioritizes FDM-based solution. Specifically, the UE first sends an IDC message requesting FDM-based solution. In case the serving eNB does not respond, the UE sends a new IDC message by alternating IDC option. Even if a TDM-based solution has been received, the UE may continue requesting FDM-based solution to gain UE performance.Type: GrantFiled: February 5, 2016Date of Patent: October 2, 2018Assignee: MEDIATEK INC.Inventors: Li-Chun Ko, Yih-Shen Chen, Yu-Ting Chen, Chung-Wei Wang, Yi-Chien Wang

Publication number: 20180013500Abstract: Concepts and examples pertaining to mitigation of coexistence interference and concurrent operations of different RF technologies are described. A processor of a network node receives a message from a user equipment (UE) using a first radio access technology (RAT). The message includes one or more information fields indicating one or more of following pieces of information regarding in-device coexistence interference experienced by the UE: an affected carrier and a range of each of one or more other RATs different from the first RAT including at least a second RAT, a suggested transmit or receive power of the UE in a first communication cell of the first RAT, and a suggested receive power of the UE in a second communication cell of the second RAT. In response to receiving the message, the processor adjusts one or more aspects of either or both of the first and the second communication cells.Type: ApplicationFiled: July 6, 2017Publication date: January 11, 2018Inventors: Shih-Chieh Liao, Chung-Wei Wang, Chi-Chen Lee

Publication number: 20150253830Abstract: A system, method, and computer-readable medium are disclosed for detecting when a lower power adapter is coupled with an information handling system having higher power requirements. More specifically, in certain embodiments, a circuit (such as an embedded controller (EC)) detects an adapter wattage when an adapter plug-in is detected. If a lower wattage power adapter is detected (e.g., a 45 W power adapter), the embedded controller activates a signal (e.g., an AC_DISABLE signal) to stop powering the information handling system from the adapter. In certain embodiments, the information handling system is powered from a battery associated with the information handling system when the power adapter power capacity does not satisfy the power requirements of the information handling system. In certain embodiments, the circuit substantially simultaneously generates a low power warning. In certain embodiments, the adapter wattage may be detected via an adapter identifier (e.g.Type: ApplicationFiled: March 10, 2014Publication date: September 10, 2015Applicant: Dell Products L.P.Inventors: Adolfo S.
