  • Patent number: 10148400
    Abstract: Embodiments of the present disclosure provide reference signal transmitting and receiving methods and devices in an active antenna system. Port virtualization to a transmit antennas may be implemented for multiple cell-specific reference signal (CRS) antenna ports and applying different vertical beamforming vectors to implement port virtualization for the different CRS antenna ports. The User Equipment (UE) reports the maximum RSRP/RSRQ value measured based on multiple CRS ports, or the UE simultaneously reports multiple RSRP/RSRQ values and the information of the multiple CRS antenna ports. Therefore, the coverage problem of the CRS signal and Physical Broadcast Channel (PBCH)/Physical Downlink Control Channel (PDCCH)/Physical Downlink Shared Channel (PDSCH) demodulated based on CRS and the problem of measurement for Radio Resource Management (RRM) in the active antenna system may be avoided. Specifically, the following problems may be solved.

  • Patent number: 10141985
    Abstract: In a wireless distribution system, a test signal(s) having a first power level is injected from a first contact point. The test signal(s) is configured to propagate from the first contact point to a second contact point over a downlink path and an uplink path, thus creating a signal loop(s). A second power level of the test signal(s) is measured at the second contact point, and an actual loop gain of the wireless distribution system is determined by subtracting the first power level from the second power level. By determining the actual loop gain of the wireless distribution system, it is possible to further determine a gain margin of the wireless distribution system. Based on the gain margin, it is possible to determine optimization possibilities for the wireless distribution system to maximize capacity and performance of the wireless distribution system.

  • Patent number: 10033594
    Abstract: Systems, apparatus, and methods are described for checkpoint summary based monitoring for an event candidate within a wireless node network of ID nodes, a master node, and a server. Such a method, for example, may have the master node receiving a first set of advertising signals broadcast by an ID node and generating a first checkpoint summary representing the first set of received signals. The master node then receives a second set of advertising signals broadcast by the ID node (after the ID node broadcasts the first set) and generates a second checkpoint summary representing the second set of received signals. The method then identifies the event candidate based upon a comparison of an observed parameter for each of the first checkpoint summary and the second checkpoint summary; and reports to the server a message about the event candidate relative to the ID node.

  • Patent number: 10015082
    Abstract: A device receives traffic; identifies an address associated with the traffic; determines whether the address is associated with an aggregate interface, the aggregate interface being associated with a first port and a second port. The first port corresponds to a first node in a first state, that indicates that the first node is available to forward the traffic, and the second port corresponds to a second node in a second state, that indicates that that the second node is not available to forward the traffic. The device transmits the traffic to the first node via the first port and to the second node, via the second port, when the address is associated with the aggregate interface. Transmitting the traffic enables the second node to forward the traffic when the first node changes from the first state to the second state.

  • Patent number: 10014970
    Abstract: Mitigation of inter-base station resynchronization loss in wireless networks including contention-based shared frequency spectrum is discussed. Aspects of such mitigation provide for base stations entering into an idle mode when a transmission opportunity occurs in a radio frame of the next resynchronization occasion. Additional aspects provide for the base station to signal a flexible listen before talk (LBT) frame length to the user equipment (UE), either with or without explicit signaling of the downlink-uplink division. Further aspects provide for the base station to signal a reset indication to UEs that will prompt the UEs to monitor for downlink channel reserving signals prior to the current LBT frame ending by the resynchronization occasion.
