  • Patent number: 10746018
    Abstract: Systems and methods for identifying a likelihood that a reservoir of a geological formation received a secondary charge of hydrocarbons of relatively very different thermal maturity of composition are provided. One method includes positioning a downhole acquisition tool in a wellbore in a geological formation and testing one or more fluid properties of the formation fluid. Data processing circuitry may identify whether a relationship of the one or more fluid properties exceeds a first threshold that indicates likely asphaltene instability. When this is the case, data processing circuitry may be used to model the geological formation using a realization scenario in which multiple charges of hydrocarbons of substantially different thermal maturity or substantially different composition, or both, filled a reservoir of the geological formation over geologic time.

  • Patent number: 9930581
    Abstract: Systems and techniques for link failure management in multiple connection systems. Upon detection of a link failure with a local area base station during a dual connection mode in which the user device is connected to a macro base station and a local area base station, a user device sends a failure indication and a measurement results report for serving and neighboring base stations to its serving macro base station, and selects a response to the failure based at least in part on evaluation information received from the macro base station. Upon detection of a link failure with a macro base station, the user device determines whether to reconnect to the macro base station or a different macro base station and whether to reconnect with the original local area base station or a different local area base station.

  • Patent number: 9900815
    Abstract: Provided in one aspect is a method for handling a frequency priority performed by a terminal in a wireless communication system. The method comprises: receiving minimum priority application request information from a network; and handling a frequency priority for cell reselection on the basis of the minimum priority application request information and the supporting characteristics of the terminal. The minimum priority application request information indicates an application of the minimum priority to a current frequency of the terminal or all frequencies of current radio access technology (RAT) of a cell which the terminal camps on. The supporting characteristic of the terminal is whether the terminal supports the RAT other than the current RAT. The handling of the frequency priority is a variable application of the frequency priority for the cell reselection according to the contents of the minimum priority application request information and the supporting characteristics of the terminal.

  • Patent number: 9854496
    Abstract: A novel and efficient connected mode cell reselection procedure is proposed to improve the mobility performance for user equipments (UEs) configured with extended connected mode Discontinuous Reception (DRX) cycle in LTE systems. A UE-centric mobility mechanism with which a UE performs cell reselection in RRC connected mode is proposed. The UE is allowed to select a target cell without handover signaling in the source cell and when needed to initiate signaling with the target cell, for which signal quality is much better. In this way, handover failures due to failed signaling in the source cell can be avoided. More specifically, the proposed mobility mechanism reduces signaling overhead and is inherently robust towards different DRX cycle settings, i.e., longer DRX cycles do not cause more failures, or more overhead, or more battery consumption.

  • Patent number: 9713148
    Abstract: Provided is a communication system that can be normally and efficiently operated in the case where existing carriers and new carrier types coexist. A base station device and a communication terminal device are configured to perform communication in cells of legacy carriers LC1 to LC3 being existing carriers. When the base station device starts operating new carrier types NCT1 and NCT2, the NCT1 and NCT2 are associated with legacy carriers belonging to the same frequency band. For example, the NCT2 is associated with the LC2 or the LC3 and is not associated with the LC1. The legacy carriers LC1 to LC3 associated with the NCT1 and the NCT2 notify the communication terminal device of the information on the NCT1 and NCT2. This allows the communication terminal device to communicate with the NCT1 and the NCT2.
