  • Patent number: 9344914
    Abstract: Aspects of the present disclosure provide wireless communication devices and methods configured to operate with multiple active connections. A user equipment establishes a first active connection associated with a first subscription. The user equipment also establishes a second active connection, simultaneous to the first active connection, associated with a second subscription. The user equipment provides modem information corresponding to connection qualities of the first active connection and second active connection, to an operating system of the user equipment. Furthermore, the user equipment mitigates contention between the first active connection and second active connection by degrading at least one of the first active connection or second active connection in accordance with a decision given by the operating system based on the modem information.

  • Publication number: 20160124411
    Abstract: Distributed energy demand management mechanisms for a distributed energy network are disclosed. In one example, a local energy controller of a local energy system determines projected energy demand information for a plurality of energy devices of the local energy system based on energy pricing information received from a central energy coordinator. The local energy controller modifies an energy consumption schedule during an energy pricing transition period based on energy access control information received from the central energy coordinator to manage a projected energy demand increase during the energy pricing transition period of the distributed energy network. In one example, the central energy coordinator determines the energy pricing information for the distributed energy network based on energy supply information and the projected energy demand information.

  • Patent number: 9332475
    Abstract: System(s) and method(s) are provided for handover of a mobile terminal in a wireless communication system. Handoff resolution relies on both a downlink channel quality indication between a serving base station and the mobile terminal, and uplink channel quality indications amongst the terminal and a measurement set of target base stations. To generate UL channel quality indicators, the mobile station conveys a narrowband or broadband sounding reference signal, and serving and target base stations measure UL and DL performance metrics (e.g., RSRP, RSSI, or RSOT). In backward handover, UL channel state information from target cells is received at the serving base station through backhaul communication, and handoff is resolved based on both UL and DL quality reports. In forward handover, the set of UL quality reports are conveyed to the mobile station to determine a target cell for handoff.

  • Publication number: 20160119804
    Abstract: Aspects described herein relate to adaptive control channel detection in wireless communications. A signal-to-interference-and-noise ratio (SINR) of a signal received by a receiver comprising multiple sub-receivers is measured, wherein the SINR is filtered according to a signal combining technology. Based at least in part on the SINR, it is determined whether to utilize the signal combining technology in combining signals related to a channel received over the multiple sub-receivers.

  • Publication number: 20160066217
    Abstract: Aspects of the present disclosure relate to a multimode user equipment (UE) that when suffering a power crunch, can intelligently reselect to another RAT to extend the battery life of the UE. The reselected RAT has a lower specified maximum transmit power relative to the currently attached RAT. Therefore, the UE may reduce its battery drain to extend its service time per charge when a call is made utilizing the reselected RAT. The UE intelligently selects the RAT that will likely consume less uplink transmit power to communicate with a base station in order to conserve battery power in a poor coverage area, when the UE is experiencing a power crunch condition.
