The UE may include a first radio which supports, e.g., simultaneously, a first radio access technology (RAT) and a second RAT. The first radio may use a lesser frequency of sleep and wake-up cycles when operating according to the first RAT than when operating according to the second RAT. The UE may perform a FEE associated with the first RAT. Accordingly, the UE may skip an FEE associated with the second RAT based on performing the FEE associated with the first RAT.Type: GrantFiled: April 1, 2014Date of Patent: March 15, 2016Assignee: Apple Inc.Inventor: Li Su

Patent number: 9282519Abstract: An apparatus and a method for controlling transmission and reception control in a wireless communication system are provided. The apparatus includes at least one voltage regulator, a power source consumer, at least one capacitor, and a controller. The at least one voltage regulator provides a power source that is a regulated voltage. The power source consumer processes a Radio Frequency (RF) signal using the power source that is the regulated voltage. The at least one capacitor is connected to an output port of the at least one voltage regulator and a power source input port of the power source consumer. The controller turns off the at least one voltage regulator during a deactivation period of the communication apparatus and turns on the at least one voltage regulator during an activation period of the communication apparatus.Type: GrantFiled: July 12, 2012Date of Patent: March 8, 2016Assignee: Samsung Electronics Co., Ltd.Inventors: Bok-Ju Park, Young-Eil Kim, Jun-Seok Yang

Patent number: 9252828Abstract: In a first antenna mode in a multi-antenna port radio access node, a set of logical antenna ports and its associated resource elements are mapped to a first set of physical antenna ports. Each physical antenna port comprises at least one power amplifier. Switching from first antenna mode to a second antenna mode is initiated upon receipt of information triggering antenna mode switching at a first point of time. During a time interval from the first point of time to a second point of time, the logical antenna ports are re-mapped to a second set of physical antenna ports. At the second point of time, at the end of the time interval, the antenna mode is switched to a second antenna mode by changing supply of power to each physical antenna port represented in the first set of physical antenna ports but not in the second set of antenna ports.Type: GrantFiled: June 13, 2012Date of Patent: February 2, 2016Assignee: Telefonaktiebolaget L M EricssonInventors: Pål Frenger, Havish Koorapaty

Patent number: 9250686Abstract: An approach is provided for monitoring, assessing, and managing power source performance. Depletion of a power source of a mobile device caused by executing a plurality of activities is determined. A duration value is determined for executing each of the activities. The duration values are attributed to the depletion. Statistical data corresponding to performance of the power source is generated.Type: GrantFiled: December 17, 2009Date of Patent: February 2, 2016Assignee: Verizon Patent and Licensing Inc.Inventors: Lakshmi Nrusimhan N. V., Priyanka G. Sriraghavan

Patent number: 9247472Abstract: A method, apparatus and computer program product are provided that continue to obtain the power saving advantages provided by discontinuous reception, while obtaining the measurement samples that are desired during a sampling time period, such as during a time to trigger period, to determine of handover is appropriate. In the context of a method, a measurement sample is caused to be obtained during a discontinuous reception monitoring period. The method may determine that a sampling time period has been commenced based upon a measurement sample. During the sampling time period, one or more additional measurement samples are to be obtained. The method may also determine that the additional measurement samples will not be obtained prior to commencement of the sleep period between monitoring periods and, as a result, cause one or more additional measurement samples to be obtained at respective times that would otherwise have been in the sleep period.Type: GrantFiled: April 3, 2012Date of Patent: January 26, 2016Assignee: Nokia Technologies OyInventor: Lars Dalsgaard

Patent number: 9247500Abstract: A power control apparatus for controlling power consumption in customer premises equipment (CPE) for use in a content and data distribution network includes a detector, operative to determine an operational status of a connection between the CPE and a headend in the content and data distribution network, and a controller coupled with the detector. The controller is operative to place the CPE in a first mode of operation when the operational status is indicative of a loss of connectivity between the CPE and the headend. The apparatus further includes switching circuitry coupled with the controller. The switching circuitry is operative in the first mode to disable power to at least a portion of a first subset of functional modules in the CPE, to thereby reduce power consumption in the CPE.Type: GrantFiled: March 15, 2013Date of Patent: January 26, 2016Assignee: TIME WARNER CABLE ENTERPRISES LLCInventors: Eric D. Hybertson, Dean E. Osborne

Patent number: 9247495Abstract: The techniques discussed herein reduce the power consumption of a Wi-Fi tethering device by switching the Wi-Fi functionality of the Wi-Fi tethering device from a normal operational mode to a sleep mode during idle intervals. The techniques implement a sleep protocol where a Wi-Fi tethering device and the Wi-Fi client device coordinate and establish a sleep schedule. Moreover, the techniques describe a sleep interval adaptation algorithm to establish sleep duration intervals based on data packet exchange patterns associated with different applications executing on the Wi-Fi client device and/or different operations being performed by the Wi-Fi client device.Type: GrantFiled: November 6, 2012Date of Patent: January 26, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Yunxin Liu, Guobin Shen, Yongguang Zhang, Hao Han
