Abstract: Disclosed is a method and system in which a PDSCH segment assigned to a UE in a particular TTI not only carries data to the UE but also carries an assignment to the UE of a PDSCH in a subsequent TTI for carrying additional data to the UE in that subsequent TTI. Such an arrangement can help make good use of possibly otherwise unused PDSCH capacity and can help to manage PDCCH capacity in the subsequent TTI.

Abstract: A system and method of scheduling communication in a wireless communication network are provided. A first access node can determine a scheduling scheme based on data addressed to wireless devices in communication with the first, second, and third access nodes. The data addressed to the wireless devices in communication with the first access node can be transmitted during a first subframe of the scheduling scheme where the first access node does not transmit data addressed to the wireless devices in communication with the first access node during a second subframe of the scheduling scheme. The second and third access nodes can be instructed to assign data addressed to wireless devices that do not meet a signal condition threshold to be transmitted during the first subframe and to assign data addressed to wireless devices that meet the signal condition threshold to be transmitted during the second subframe.

Abstract: Aspects of selecting a base station for a UE device are described. The UE device or a wireless network component (e.g., a base station) can determine RF uplink use values of a coverage area. The RF uplink use values can be received from one or more base stations and can be based on a subframe or other time segment. A processor can determine a base station having a greatest number of subframes with at least one resource block available. If the base stations have an equal number of subframes having at least one resource block available, the processor can determine which base station has a greatest number of subframes having at least two resource blocks available (or three, etc. if additional ties exist). A selection of the base station can be based on the processor's determination and whether the UE device is located within an edge of a coverage area.

Abstract: Disclosed is a method and system for managing signaling in wireless communication network. Base stations in the network will be divided into groups, but each base station's coverage area will be deemed a separate respective tracking area, and, for each group of base stations, an intermediary will manage transmission of registration and paging signaling between a paging controller and the group of base stations. In practice, when a tracking-area update (TAU) arrives from a WCD in coverage of the group of base stations, the intermediary may forward the TAU to the paging controller only if the TAU represents the WCD's movement into coverage of the group of base stations. Further, when a paging message arrives for a WCD, the intermediary may forward the paging message to the appropriate base station in the group.

Abstract: A computer-implemented method, network management system, and network clients are provided for out-of-band network security management. The network management system includes routers, firewalls, and out-of-band interfaces. The out-of-band interface of the network management system transmits access control lists to network clients connected to a trusted network. The trusted network connects the routers, firewalls, and network clients. The firewalls receive access control lists from the network management system to police communications that traverse the trusted network and an untrusted network. The routers receive access control lists from the network management system to police communications that traverse the router within the trusted network. The access control lists for the routers and firewalls are transmitted over a network interface to the trusted network and are transmitted separately from the access control lists for the network clients.

Abstract: A system and method of scheduling communication in a wireless communication network are provided. A first access node can receive an uplink scheduling request from a wireless device. The first access node can receive a first interference indicator from a second access node when the wireless device is located at the cell edge. A first scheduling scheme for the first access node and a second scheduling scheme for the second access node can be determined based on the uplink scheduling request and the interference indicator. The uplink portions of the first scheduling scheme do not overlap the uplink portions of the second scheduling scheme. The first access node can instruct the wireless device to communicate uplink data to the first access node during the uplink portions of the first scheduling scheme and to communicate uplink data to the second access node during the uplink portions of the second scheduling scheme.

Abstract: A method and apparatus to help manage communication on a wireless channel. When a neighboring node detects on a wireless channel a ready-to-send (RTS) message from a transmitting node to a receiving node, the neighboring node will set itself to avoid transmission on the channel for a time period but will then determine whether it detects in that time period a further transmission from the transmitting node to the receiving node, related to the data transmission. The further transmission may be a confirmation-to-send (CoTS) message that the transmitting node sends to the receiving node in response to a clear-to-send (CTS) from the receiving node. If the determination is affirmative, then the neighboring node will continue avoiding use of the channel. But if the determination is negative, then the neighboring node will discontinue avoiding use of the channel.

Abstract: One or more random access channel (RACH) instances may be specially designated for use by mobile terminals that are in threshold poor coverage of an intended base station. Further, one or more other base stations that provide coverage overlapping with, within, or near coverage of the intended base station may be arranged to monitor the one or more specially designated RACH instances for mobile terminal access requests and, upon detecting any such access request, to forward the access request via an inter-base station link to the intended base station. The intended base station may then respond to the mobile terminal access request through a direct downlink communication to the mobile terminal.
