  • Patent number: 10694462
    Abstract: A downlink scheduling data monitoring method, a downlink scheduling data sending method, and an apparatus are provided. The method includes: starting a timer; and after it is determined that the timer expires, monitoring, by using a first discontinuous reception DRX monitoring cycle, downlink scheduling data sent by a base station, where duration of the first DRX monitoring cycle is in a unit of minute or hour. After it is determined that the timer expires, the downlink scheduling data is monitored by using the first DRX monitoring cycle whose duration is in a unit of minute or hour. In this way, not only power consumption is reduced, but also the downlink scheduling data can be monitored.

  • Patent number: 10694477
    Abstract: Systems and methods are disclosed herein relating to beam-switching in a wireless system. In some embodiments, a method of operation of a User Equipment device (UE) that transmits and/or receives to and/or from a source Antenna Node (AN) on a source beam comprises performing a Mobility Reference Signal (MRS) search to attempt to detect MRS transmitted by one or more candidate ANs for one or more candidate beam. The method further comprises, if one or more conditions that are indicative of the MRS search being unsuccessful are met, transmitting an indication that the MRS search was unsuccessful. In this manner, one or more network nodes are informed that an action(s) (e.g., assisted beam-formed MRS transmission and/or increasing MRS transmit power at candidate AN(s)) needs to be taken to enable a successful MRS search by the UE.

The system can determine which UEs are capable of using each type of network and which services or applications that are suitable for use on each type of network. Due to differences in propagation and penetration distances of various frequency spectrums, the system can also determine which UEs have sufficient signal strength for each type of network. The system can reside on the network, on the UEs, or on both the network and the UE. The system can switch back and forth between multiple networks as conditions, applications, or other factors change.

    Abstract: A communication system capable of preventing unnecessary switching of an energy saving cell between a normal operation state and an energy saving state. An energy saving cell (ES cell) is in a dormant state that is the energy saving state. In this case, when being notified of a wake-up request message from a communication terminal device (UE), the ES cell executes access restriction control to judge whether the UE can access its own cell. If judging that the UE can access its own cell, the ES cell switches on its own cell and shifts from the dormant state to an active state that is the normal operation state.

When a base station indicates an uplink signaling reduction mechanism in first RRC signaling or second RRC signaling, a UE enables the uplink signaling reduction mechanism. The UE selects, based on macro cell uplink resources, to camp on a macro cell or to access a small cell controlled by a plurality of RSUs. The UE reports current location information through an X2 interface between the RSUs and an X2 interface between the RSU and the base station. The first RRC signaling is used for sending system information in system information broadcast.

  • Patent number: 10645622
    Abstract: A user terminal selects small cells in a radio communication system in which a macro cell and small cells are arranged to overlap each other. In the cell selection method of the present invention, a macro base station to form a macro cell carries out the steps of determining the offset value to use in cell selection in a user terminal based on transmission property information of a second carrier in the small cell, and reporting the offset value to the user terminal. Also, the user terminal carries out the steps of measuring the received quality of reference signals from the macro base station and the small base station, receiving the offset value that is reported from the macro base station, and carrying out cell selection based on the received quality that is measured and the offset value that is received.

  • Patent number: 10638387
    Abstract: A system for delaying or inhibiting data is provided in order to shorten the time required for a reselection process from a first communication protocol to a second communication protocol. Reselection from the first communication protocol to the second communication protocol (e.g., 3G to 4G) requires a period of time without data transfers to allow the reselection to complete. The system delays or inhibits data transfers on the mobile device until the reselection process completes or the mobile device is idle for a predetermined length of time. In an embodiment, the system can buffer outgoing data and then send the data once the reselection has completed. In other embodiments, the system can drop packet sessions or ignore incoming packet pages. In another embodiment, the system can delay or inhibit data based on the priority of the data.

  • Patent number: 10638337
    Abstract: Various embodiments disclosed herein provide for multi-stage segmentation of downlink control information. Downlink control information can arrive at a user equipment on more than one channel, setting up and configuring data channels for different base stations, or data channels for the same base station but where the data channels are in different frequency domains or time domains. The downlink control information segmentation system disclosed herein can determine when downlink control information for the user equipment is common across a plurality of downlink control channels, and ensure that the downlink control information is sent just one time, to avoid redundant data transmissions and increased overhead.

  • Patent number: 10638453
    Abstract: The described aspects include methods and apparatus for activating a transmitter to communicate in a wireless network. A small cell can determine to activate the transmitter to serve user equipment (UE) in a wireless network. The small cell can then broadcast a portion of a set of broadcast signals in a radio frame and broadcast a remaining portion of the set of broadcast signals along with the portion of the set of broadcast signals in a subsequent radio frame. By refraining from immediately broadcasting all broadcast signals, the small cell can mitigate interference to other small cells. In addition, a UE can determine whether to generate random access channel (RACH) sequences for proximity determination or uplink timing synchronization based on parameters received in a RACH order. Moreover, a small cell with an active transmitter can decode discovery signals from a device to facilitate handover determination.
