  • Patent number: 9734860
    Abstract: Systems and methods are disclosed relating generally to data processing, and more particularly to applying low pass and rotation filtering in relation to data processing. For example, a system may include a phase modification value determination circuit operable to generate a phase offset value based upon an input data set derived from information sensed from a storage medium. The system may include an integrated low pass and rotation filtering circuit operable to simultaneously apply a low pass filtering function and phase rotation function to a series of digital samples derived from the information sensed from the storage medium to yield a modified output. Application of both the low pass filtering and phase rotation functions is governed at least in part based upon a selected coefficient set corresponding to a combination of the phase off set value and a boost value.

  • Publication number: 20170181016
    Abstract: The present invention provides a method and device for subscribing to an RLF report. An integration reference point manager configures a subscription condition for an RLF report for an integration reference point agent. The integration reference point manager obtains an RLF report that is sent by the integration reference point agent and satisfies the subscription condition. The present invention can avoid that a base station sends an RLF report obtained from a UE, to an IRPManager through an IRPAgent in a best-effort mode, thereby decreasing the load of information transferred between the IRPManager and the IRPAgent.

  • Patent number: 9585093
    Abstract: The present invention provides an energy-saving control method for a cell in a heterogeneous system, including: receiving, by an access control device of a serving cell, a service request of a multi-mode user equipment UE; and when a radio resource of the serving cell cannot satisfy the service request of the multi-mode UE, if the access control device of the serving cell determines that a heterogeneous-system neighboring cell of the serving cell is in an energy-saving state, sending, by the access control device of the serving cell, an exit energy-saving state request message to an access control device of the heterogeneous-system neighboring cell, where the exit energy-saving state request message is used to request the heterogeneous-system neighboring cell to exit the energy-saving state. The technical solution implements energy-saving control for a cell in a heterogeneous system.
