Patent number: 11515933Abstract: Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.Type: GrantFiled: October 2, 2020Date of Patent: November 29, 2022Assignee: ViaSat, Inc.Inventors: Kenneth V.

Patent number: 10142964Abstract: A method and system signal resource allocation information in an asymmetric multicarrier communication network. A MS communicates with a BS using asymmetric carriers consisting of at least one low frequency carrier (e.g., primary carriers) in a cellular band and at least one high frequency carrier (e.g., secondary carriers) in a millimeter Wave band. In one embodiment, the BS allocates resources for one or more transmit time intervals in at least one of DL allocation interval of a secondary DL carrier and UL allocation interval of a secondary UL carrier for the MS, where the DL allocation interval spans one or more subframes of the secondary DL carrier and the UL allocation interval spans one or more subframes of the secondary UL carrier. The BS then transmits information regarding the allocated resources to the MS in a Packet Data Control Channel region of a subframe of the primary DL carrier.Type: GrantFiled: September 9, 2013Date of Patent: November 27, 2018Assignee: Samsung Electronics Co., Ltd.Inventors: Anshuman Nigam, Anil Agiwal, Young-Bin Chang

Patent number: 10121210Abstract: During operation, an electronic device monitors data associated with different power states received from another electronic device via an interface circuit. Using the monitored data, the electronic device calculates a time duration that the other electronic device is in an active operating mode. Moreover, the electronic device determines power states of the other electronic device based on the calculated time duration and/or a time duration between times when data is received. Next, the electronic device calculates the power-consumption history of the other electronic device based on the determined power states and at least a model of power consumption in different power states of the other electronic device. By calculating the power-consumption history of the other electronic device, the electronic device may significantly improve the accuracy of a power-usage model for the other electronic device.Type: GrantFiled: September 26, 2012Date of Patent: November 6, 2018Assignee: Apple Inc.Inventors: Andrew D.
