  • Publication number: 20140348079
    Abstract: A user equipment (UE) has established a first radio link with a serving network node and a second device-to-device (D2D) radio link directly with another user equipment (UE). In response to having D2D data to send to the other UE over the D2D radio link, the UE sends to the serving network node on the first link a request for radio resources for a layer 1 (L1) control channel; and in response to an assignment of D2D resources by the serving network node in reply to that request, the UE sends on the assigned D2D resources to the other UE the D2D data and the L1 control channel. In one example the request includes an indication of the UE's link adaptation for the L1 control channel such as format for a PDCCH or ePDCCH and/or aggregation level.

  • Publication number: 20140348082
    Abstract: A method and system is disclosed for grouping the multiple stations connected to an access point (AP). The system and method comprise sending a sounding packet to a plurality of stations, wherein the stations may be all or part of the stations that are located within the range of the AP. The stations that receive the sounding packets respond to the AP, and the AP determines the channel state information (CSI) from the responses. According to the CSI, the AP divides the multiple stations into several groups. According to an embodiment of the present invention, a confirmation step is performed to each group of stations, respectively. The AP sends a second sounding packet to each group of stations, and verifies the CSI between each station group by group. Therefore, the method and system provides for monitoring the validation of each group by periodically sending sounding packets to each group.

    Abstract: First and second receivers are used to receive respective first and second signals, to process said first and second signals and provide respective first and second measures thereof to respective first and second transmitters. The first and second transmitters are configured to launch the first and second measures, respectively, each comprising a desired component that has originated at a desired source, and an interference component that has originated at an interfering source. The first and/or second transmitters are configured to process and launch the respective first and second measures, properly conditioned, so that upon interception thereof by a receiving element the interference components thereof add destructively and substantially cancel (or at least partially cancel) each other, whereas the desired components avoid substantial cancellation owing to a phase relationship therebetween that differs relative to a phase relationship between the interference components.

    Abstract: Disclosed are a wireless communication base station device and a division number determination method that improve the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit.

    Abstract: Disclosed are a system and method for moving a connection from a localized network, e.g., a personal area network (“PAN”), to a different or larger network, e.g., a wide area network (“WAN”). In one aspect, wherein two devices are in communication on a PAN, each device uses the PAN to query the IPv6 WAN prefix assigned to each other device to which it is communicating on the PAN. The querying device then creates a globally routable IPv6 address for the desired communication and uses it to continue the connection after the device detects that the PAN is out of range. In an embodiment, one of the endpoint devices may determine that it has changed its IPv6 prefix and may transmit the new prefix to the other device through an out-of-band method such as the Short Message Service.
