  • Publication number: 20180160428
    Abstract: A mobile station receives a downlink control structure in a first carrier, where the downlink control structure indicates that control information for the mobile station is on a second, different carrier. The mobile station decodes the control information in the second carrier, where the control information specifies resource allocation of a wireless link for the mobile station. More specifically, according to some implementations, the control channel in the first carrier specifies the resource allocation for an extended control channel in the second carrier, where the extended control channel specifies the resource allocation for traffic data of a wireless link for the mobile station.

  • Publication number: 20170343642
    Abstract: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.

  • Publication number: 20170332290
    Abstract: In a wireless communications network, the presence of a wireless local area network in a cell segment is determined. An identifier of the wireless local area network in the cell segment is sent to at least one mobile station in the cell segment to enable the at least one mobile station to hand off to the wireless local area network. Optionally, information identifying geographic boundaries of cell segments and the wireless local area network can be sent to the at least one mobile station.

  • Patent number: 9788216
    Abstract: A wireless network includes a plurality of small cells. The small cells each register with the network, and an application server tracks the locations of the small cells within the network. Upon entry to the network, the small cell registers with various event packages managed by the application server. When a small cell in the network updates its configurations and/or parameters, the small cell publishes those changes to the application server. The application server determines other nearby small cells that are “interested” in those changes based on their proximity to the changed cell. The application server then notifies those proximate cells of the changes made to the changed cell so that the proximate cells can update their own configurations.

  • Patent number: 9007990
    Abstract: A packet-switched wireless communications network includes a mobile station and a radio network controller that are able to establish a radio connection therebetween. Messages are exchanges over one or more traffic channels to establish a packet-switched services session between the mobile station and the radio network controller. The radio connection is not closed until all messages for establishing the packet-switched services session have been exchanged between the mobile station and the radio network controller.
