  • Patent number: 9264968
    Abstract: Device-to-device (D2D) communications in conjunction with carrier aggregation. A base station (BS) may coordinate D2D communication between two wireless user equipment (UE) devices. A primary cell may be configured for communicating with each of the UEs. A secondary cell may be configured for D2D communication between the two UEs. The primary cell and the secondary cell may utilize different component carriers. Additionally, cross-carrier scheduling may be used, such that at least some control information for the secondary cell is communicated via the primary cell.

  • Publication number: 20150095955
    Abstract: An electronic device uses one antenna to wirelessly communicate information with two different wireless networks via concurrent connections associated with different radio access technologies. More specifically, the electronic device may receive video via a first of the connections using a multicast communication protocol. In order to maintain the second connection, the electronic device may switch, for a time interval, from the first connection to the second connection during switching events. This switching can disrupt displayed content associated with the video. To prevent this disruption, in response to a trigger that warns of an upcoming switching event, the electronic device accesses a portion of the video in a buffer during the time interval associated with the switching event. When the communication circuit switches back to the first connection after the switching event, the electronic device reverts to the video communication using the multicast communication protocol.

  • Publication number: 20150031367
    Abstract: An apparatus, system, and method for performing handover of a mobile station (MS) between a base station (BS) and an access point (AP) are described. In one embodiment, the MS may receive one or more threshold values for reporting measurements to the BS. The MS may convert the threshold values to device-specific threshold values. The MS may determine one or more network quality values associated with the AP. The MS may compare the network quality values to the device-specific threshold values. In response to the network quality values exceeding the device-specific threshold values, the MS may convert the network quality values to calibrated network quality values. The MS may provide the calibrated network quality values. The MS may perform handover from the BS to the AP based on providing the calibrated network quality values to the BS.

  • Publication number: 20140328185
    Abstract: A method and system for communicating header compression layer control messages. Header compression control messages are generated by a header compression layer (302) and are sent through at least one link layer data packet by a link transport communications protocol layer (304) to a remote receiver (104). The link transport communications protocol layer (304) monitors receipt of link layer data packet acknowledgements that are received from the link transport communications protocol layer (304) of the remote receiver (104) for the at least one link layer data packet. The link transport communications protocol layer (304) determines successful transmission of the header compression control message and provides, to the header compression layer (302), an indication of successful header compression control message transmission.

  • Publication number: 20140247811
    Abstract: A wireless communication system is presented for robust mobility management in a HetNet communication system. A source cell can prepare a macro cell and a target small cell as handover candidates during handover decision making and/or preparation. The mobile device is informed about the prepared macro cell and target small cell using radio resource control (RRC) messaging. After receiving a handover command or detecting radio frequency (RF) loss, the mobile device can try to connect with the target small cell. If the mobile device is unable to connect to the target small cell, the UE can fall back and connect to the macro cell.

  • Publication number: 20140241243
    Abstract: A method for redundant transmission of real time data is provided. The method can include an edge node in a wireless network sending a first RTP packet including a first real time data frame to a second edge node. The method can further include the edge node determining that a radio link condition is sufficient to support redundant transmission of real time data to the second edge node. The method can additionally include the edge node, in response to determining that the radio link condition is sufficient to support redundant transmission of real time data, bundling the first real time data frame with a next sequential real time data frame that has not been previously sent to the second edge node in a second RTP packet at a PDCP layer of the edge node; and sending the second RTP packet to the second edge node.

  • Publication number: 20130155918
    Abstract: A method includes, in response to a determination a received packet has information in a header of the packet that if modified with other information would allow a subsequent header compression to compress the header to a larger degree than if the information was not modified, modifying the information with the other information. The method also includes compressing at least the header and transmitting the packet including the compressed header. Another method includes, in response to a determination a received packet has a sequential identification in a header of the packet, modifying the sequential identification to a random identification; and transmitting the packet to a core network. Apparatus and program products are also disclosed.
