Patent number: 11184856Abstract: This disclosure relates to a method for reducing power consumption of a first device for use in a wireless communication system. The first device receives a signal within a first reference sub-frame of a radio channel. The device determines whether to use the signal for obtaining channel state information to be reported to a second device within a reporting sub-frame, or whether to receive and use a second signal within a second reference sub-frame of the radio channel for obtaining channel state information to be reported to the second device within said predetermined later sub-frame. Based on this determination, the first device reports channel state information obtained based on the signal received within said first reference sub-frame or said second signal within said second reference sub-frame to the second device within said reporting sub-frame.Type: GrantFiled: June 2, 2016Date of Patent: November 23, 2021Assignee: Apple Inc.Inventors: Sven Dortmund, Mathias Kurth, Matthias Hofmann, Sabine Roessel

Patent number: 10271374Abstract: The UE VoIP engine monitors the network pattern periodicity and implements a scalable scheduling strategy that can adapt the VoIP engine and audio driver scheduling to the current local radio configuration in one embodiment. By adapting its scheduling, the VoIP engine can reduce mouth-to-ear delay or power consumption without impacting the audio encoding quality. The UE VoIP engine sends some scheduling preference to the network base station. The network base station monitors UE preferences and decide whether to ignore or accept UE preferences and allows the UE to operate in the conditions that provides the best tradeoff between power consumption and mouth-to-ear delay.Type: GrantFiled: December 8, 2015Date of Patent: April 23, 2019Assignee: Intel CorporationInventors: David Giguet, Eric Perraud, Jerome Parron, Sven Dortmund

Patent number: 9787742Abstract: A user equipment device (UE) comprises physical layer circuitry configured to transmit and receive radio frequency electrical signals with one or more nodes of a radio access network, an audio subsystem configured to generate frames of audio data, and processing circuitry. The processing circuitry is configured to calculate a time delay from generation of an audio data frame by the audio subsystem of the UE device to transmission of an audio data packet by the physical layer circuitry during a voice call, and decrease the time delay to a delay value that preserves a specified minimum time for delivery of the generated audio data frame to the physical layer circuitry to meet a scheduled transmission time of the audio data packet.Type: GrantFiled: September 29, 2014Date of Patent: October 10, 2017Assignee: Intel CorporationInventors: Sven Dortmund, David Giguet, Benoit Guilhaumon, Eric Perraud, Philippe Weingertner, Jerome Parron
