  • Patent number: 10080100
    Abstract: Techniques and systems are disclosed for enhancing the flexibility and resiliency of mobile social networking platforms. Techniques enable dynamic, user-defined check-in points with mobile devices so that users may define ad hoc, location-based communities. Techniques may also selectively determine an appropriate location-sensing mechanism to improve location accuracy or privacy, or to compensate for unavailable location-sensing capabilities. The techniques may assist social networking platforms to have a greater range of check-in options and to enable communication that may not rely on traditional network connectivity. In some cases, devices belonging to participators outside the member group may be used to locate a member who has moved outside the detection zone of a check-in point. In some cases, the participators' devices might not be directly connected to the lost member device but instead are connected via one or more “hops” of indirect communication with other participator devices.

  • Patent number: 10069583
    Abstract: A method and system are provided for synchronizing local clocks more quickly in a telecommunication network using IEEE 1588. A network element that receives timing signals from one or more possible parent clocks considers a measure of the reliability of the timing signals contained in Announce messages from the parent clock or clocks. The clock uses this reliability information in selecting one of the possible parent clock or clocks to use as the actual parent clock. Once the selection is made, the clock adjusts the filtering characteristics applied to timing signals received from the selected parent clock. The adjustments reflect how confident the parent clock is as to how stable the timing information it provides has become. If the indication of reliability contained in Announce messages received from the parent clock indicates that the timing information is not very reliable, then a high filter bandwidth is used in filtering the timing signals.

The UE may determine the DTX state of each serving cell from the DTX DCI format and monitor an enhanced PDCCH of each serving cell in the non-DTX state to provide a scheduling assignment for the UE, without monitoring each serving cell in the DTX state. The UE may receive higher layer signaling that indicates a repetition period and subframe offset for DTX DCI format transmissions or a bitmap of the DTX DCI format transmissions for subframes within each modification period.

As such, the two wireless devices may then establish one or more D2D connections using the negotiated compatible RAT(s).

  • Patent number: 10069524
    Abstract: The wireless communication method used for transmitting interfering resource allocation information (IRAI) comprises a step of transmitting the IRAI through L1 signaling from the serving eNB to the victim UE, wherein the IRAI indicates only interfering resource block (RB) allocation within the bandwidth of RBs allocated to the victim UE at least in the case that the resource allocation type of the interfering UE is type 0, type 1, or type 2-L. The resource allocation type of the interfering UE can be signaled from the serving eNB to the victim UE within the downlink control information (DCI) of the victim UE for allocating resource. The indication mode of the IRAI for at least one interfering UE among the multiple interfering UEs that belong to a same interfering cell can be dependent on those interfering UEs whose IRAI has been indicated among the multiple interfering UEs.

  • Patent number: 10070389
    Abstract: A relay apparatus for data relay between multiple communication lines includes a sleep relay unit, a start-up determination unit and a communication block unit. The sleep relay unit relays a sleep instruction that instructs a designated apparatus to transition to a sleep mode. The start-up determination unit determines whether or not a start-up apparatus, which is an apparatus other than the designated apparatus and is in a normal mode, exists in a designated communication line, which is a communication line connected to the designated apparatus. Communication that uses the designated communication line is blocked by the communication block unit when it is determined that the start-up apparatus does not exist in the designated communication line.

  • Patent number: 10070396
    Abstract: Network node and method therein for inter cell interference coordination. A method in a network node comprises estimating spatial properties of a radio channel between a base station and at least part of an underlay/neighboring cell based on information about spatial properties of a radio channel between the base station and a respective at least one user equipment (UE) located in a region associated with inter cell interference in relation to the underlay/neighboring cell. A transmission is adapted to a UE, served by the base station in a reduced power subframe, based on a correlation between the spatial properties of the radio channel and estimated spatial properties of a radio channel between the base station and the UE. The method enables control of interference subjected towards the underlay/neighboring cell, caused by downlink transmission to the UE.

    Abstract: The disclosure provides for reporting a channel quality indicator (CQI) in wireless communications. A user equipment (UE) may determine that a calculated CQI value to be reported in a current sub-frame is affected by a deterministic null scheduling on a downlink channel. The UE may determine a compensatory CQI value. The UE may report the lesser of the calculated CQI value and the compensatory CQI value in response to determining that the calculated CQI value is affected by the deterministic null scheduling. In an aspect, the deterministic null scheduling is associated with a compressed mode gap. The UE may determine whether the calculated CQI value is affected by the deterministic null scheduling by determining whether the current sub-frame is within a first time period before the start of the compressed mode gap or within a second time period after the end of the compressed mode gap.
