  • Patent number: 10244444
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive data from both a source base station and a target base station during handover. For example, the UE may refrain from resetting or reestablishing media access control (MAC) and packet data convergence protocol (PDCP) layer configurations until after a successful access procedure is performed with the target base station. In some cases, a single radio link control (RLC)/PDCP stack may be used during handover procedures. A source base station may, for example, forward data to a target base station after receiving a handover execution message. A UE may identify and resolve any duplicate data sent by both base stations during the transition. Additional signaling may be used (e.g., during the radio resource control (RRC) configuration) to indicate that a UE supports dual link handover.

    Abstract: A method and apparatus for searching for closed subscriber group (CSG) cells are described. A wireless transmit/receive unit (WTRU) transmits, to a network of CSG cells, a measurement/cell-search gap request message including a cause value having at least one bit that indicates whether the request message was transmitted due to a manual cell search command or a WTRU autonomous determination. The WTRU receives a measurement/cell-search gap allocation message from the network in response to the measurement/cell-search request message. The WTRU also may determine whether it has a discontinuous reception (DRX) gap that is long enough to read a master information block (MIB) and a system information block (SIB) of a neighboring CSG cell. If the DRX gap is not long enough, the WTRU may transmit a measurement/cell-search gap request message to the network, or autonomously tune away from a cell currently serving the WTRU to read the MIB and SIB.

    Abstract: Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) including communicating via each one of multiple available signal channels. Data packets exchanged between a tester and DUT as a normal part of a communication link initiation sequence are exchanged in such a manner that the tester transmits with varied signal power via all available channels simultaneously, thereby ensuring that a properly working DUT will transmit in response to reception of tester data packets having sufficient signal power. For example, in the case of a Bluetooth low energy transceiver, advertisement, scan request and scan response data packets can be used in such manner.

  • Patent number: 9820192
    Abstract: A handover proactive association clearing support method and system supports minimizing handover times for at least one netsurfing end system, and optimizing a given market satisfaction function (MSF0) potentially depending on Internet-applications for whichever underlying HO technique, by potentially establishing pre-HO for free x/yz-, netsurfing x/yz-, and/or Sxyzj-association, called “clearing” them. An HO of an Ayz is optimal if its HO-time is “basically zero” and it complies with MSF0. The technical innovation of the method and system comprises for an Ayz determining any time its optimal HOs. This permanent predetermination of optimal HOs implies assessing permanently all parameters. Thus, when an Ayz must perform an HO, these pre-HO operations of the method/system would have already identified at least one optimal HO for it to a sharedIADx and/or an Sxyzj available to it and established the resp. x/yz-, netsurfing x/yz-, and Sxyzj-associations.

  • Patent number: 9775054
    Abstract: A wireless communication link can include an uplink and a downlink between a wireless access point and a computer device. The uplink supports communications from the computer device to the wireless access point. The downlink supports communications from the wireless access point to the computer device. The computer device executes a downlink monitor application to monitor events occurring on the downlink. The wireless access point or other suitable resource such as a remote management resource executes an uplink monitor application to monitor events occurring on the uplink. The uplink application and the downlink application log events using the same master clock. The remote management resource can be configured to analyze the uplink status information in view of the downlink status information to perform one or more functions such as troubleshooting, optimizing network settings, etc.

  • Patent number: 9655128
    Abstract: A scheduling process handles a plurality of communication services in a collective manner, thus making a radio communications system more operable. A pilot signal sender sends pilot signals with carrier frequencies each corresponding to an N (N?1) different communication services. A scheduler collects N×n instances of propagation environment data from n (n?1) terminal devices and selects terminal devices and communication services therefor by assigning terminal devices having a better propagation environment to the plurality of different communication services in a collective manner. The pilot signals are used by a propagation environment data sender to measure and report a propagation environment of each carrier frequency. A communication function configurer automatically sets up a communication function to adapt to the communication service that the base station has assigned.
