Patent number: 8913536Abstract: The present invention provides a DRX control method and system in which power consumption of a mobile station can be reduced and an increase in the load of a network can be suppressed. A source base station forwards Dormancy Context, which is information for controlling the activity level of a mobile station that performs inter base station handover, to a target base station and, immediately after the mobile station completes handover, the target base station performs DRX control of the mobile station using the Dormancy Context.Type: GrantFiled: November 8, 2012Date of Patent: December 16, 2014Assignee: NEC CorporationInventors: Hisashi Futaki, Jinsock Lee

Patent number: 8908581Abstract: Systems and methodologies are described that facilitate operating an access terminal in an LTE based wireless communication environment utilizing extended microsleep. While in non-DRX mode, an access terminal can operate in on state for a first period of time and in extended microsleep state for a second period of time. Further, the first and second periods of time can form a repeating pattern where these periods of time alternate. Thus, the access terminal can turn on its receiver for the first period of time (e.g., decode downlink information while in on state) and turn off its receiver for the second period of time (e.g., inhibit decoding of downlink information while in extended microsleep state). Further, the first period of time in the repeating pattern can be one TTI (e.g., 1 ms) and the second period of time in the repeating pattern can be a plurality of TTIs (e.g., 5 ms).Type: GrantFiled: April 30, 2008Date of Patent: December 9, 2014Assignee: QUALCOMM IncorporatedInventors: Sai Yiu Duncan Ho, Aleksandar Damnjanovic

Patent number: 8902802Abstract: Disclosed are a terminal device for receiving a signal in a wireless communication system for supporting a plurality of component carriers and a method thereof. In the terminal device for receiving the signal in the system for supporting the component carriers, a receiver receives a Physical Downlink Control Channel (PDCCH) including control information of a first type component carrier from a base station or a relay. A processor performs a decoding operation or controls an operation in a slip mode on the basis of control information included in a PDCCH in a second type component carrier after a time corresponding to a particular time offset value passes from a transmission time point of the PDCCH.Type: GrantFiled: November 30, 2010Date of Patent: December 2, 2014Assignee: LG Electronics Inc.Inventors: Kyu Jin Park, Sung Ho Moon, Jae Hoon Chung, Seung Hee Han, Yeong Hyeon Kwon, Han Gyu Cho

Patent number: 8902803Abstract: Systems, methods, and devices for reducing collisions in a wireless communications network are described herein. In some aspects, a receiver receives a paging message. The paging message includes an ordering and a multiplier. A processor determines a first wake-up time based on the ordering and the multiplier. The wireless device wakes up at the determined wake-up time. The wireless device receives data via the receiver.Type: GrantFiled: January 23, 2013Date of Patent: December 2, 2014Assignee: QUALCOMM IncorporatedInventors: Alfred Asterjadhi, Simone Merlin, Maarten Menzo Wentink, Santosh Paul Abraham, Zhi Quan

Patent number: 8902797Abstract: The present disclosure generally relates to techniques to reduce energy consumption in a multiple-input multiple-output (MIMO) system. Some example embodiments may include collecting a set of information associated with one or more of an energy consumption, a network traffic condition, an environmental condition, and/or quality of a communication link associated with the first wireless communication device and/or the MIMO system, configuring the first wireless communication device to operate at a first reduced energy consumption level based on the collected set of information, identifying operation information associated with the first wireless communication device based upon at least the configuration of the first wireless communication device, and transmitting the operation information for reception by the second wireless communication device so that the second wireless communication device can be configured to operate at a second reduced energy consumption level based on the operation information.Type: GrantFiled: August 11, 2009Date of Patent: December 2, 2014Assignee: Empire Technology Development LLCInventor: Miodrag Potkonjak
