  • Patent number: 10136359
    Abstract: Aspects of the disclosure relate to network management and routing protocols in communication networks, including but not limited to wireless communication networks including Integrated-Access-Backhaul (IAB) nodes within an IAB network. In some examples, one or more traffic flows between an IAB node and a remote network may be migrated from a first tunnel associated with a first network routing domain to a second tunnel associated with a second routing domain in accordance with route information pertaining to each of the network routing domains. In various examples, the migration may be performed in response to a failure of a wireless link in the IAB network, while in other examples, the migration may be performed in response to congestion or overloading of an IAB node.

  • Patent number: 10075182
    Abstract: Methods and apparatus related to message compression/decompression are described. A compressed message is generated by indicating what changes are to be made to a previous message to produce the message sought to be transmitted. The required change, in the form of at least one command and corresponding parameter, is transmitted as a compressed version of the message being communicated. This approach takes advantage of the fact that messages sent over time often include much of the same message content and only one or a few fields may have changed. The techniques are general and involve including a command in the compressed message along with at least one parameter. The command indicates processing to be performed on a previous message to generate the uncompressed message. The parameter may be, e.g., data to be inserted into the previous message or specify a location in the previous message where the change is to be made.

  • Patent number: 10009260
    Abstract: Aspects of the disclosure relate to network management in communication networks, including but not limited to wireless communication networks including integrated access and backhaul (IAB) nodes within an IAB backhaul network. For example, a network node may determine to integrate a peer node, to which the network node has physical connectivity, into a network routing domain of which the routing node is a member. In another example, a network node may determine to truncate a peer node from a network routing domain. In various examples, the decisions to propagate or truncate the network routing domain may be made based on routing messages within a network routing domain, or in a plurality of overlapping network routing domains. In further examples, the decisions may be based on information about physical links between respective nodes.

  • Patent number: 9578654
    Abstract: Methods and apparatus related to wireless terminal reporting alternative selection for a fixed bit size control information request report, e.g., a 4 bit uplink traffic channel request report, are described. A wireless terminal maintains a plurality of different request groups corresponding to uplink traffic to be transmitted. The same request report format includes a plurality of reporting alternatives, different reporting alternatives corresponding to different request groups. Backlog can and sometimes does exist simultaneously corresponding to request groups corresponding to different reporting alternatives. The wireless terminal uses priority information associated with the request groups having non-zero backlog to select a reporting alternative. In some embodiments, at least some of the request groups have priorities which are calculated by the wireless terminal and change as a function of determined transmission deadline information.

  • Patent number: 9083355
    Abstract: Methods and apparatus for using end nodes, e.g., wireless terminals, to discover base stations and communicate information about discovered access nodes, e.g., base stations, to other access nodes in a system are described. As the wireless terminal roams in the system and new access nodes are encountered, one or more physically adjacent access nodes will be informed of the presence of the new access node as a result of communications with the wireless terminal. A message indicating an access node's inability to route a message to another access node which is known to a wireless terminal may trigger the wireless terminal to begin the process of updating access node routing and neighbor information.

  • Patent number: 8929270
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives indication of a transmission scheme for decoding multicast/broadcast data transmitted from a sender, receives a reservation signal for the multicast/broadcast data from the sender, determines whether the receiver is capable of decoding the multicast/broadcast data at the indicated transmission scheme, and transmits a confirmation signal for the multicast/broadcast data to the sender after determining that the receiver is capable of decoding the multicast/broadcast data at the indicated transmission scheme. The apparatus receives the multicast/broadcast data according to the transmission scheme after the confirmation signal is transmitted. Alternatively, the apparatus suppresses transmission of the confirmation signal when it is determined that the receiver is not capable of decoding the multicast/broadcast data at the indicated transmission scheme.

  • Patent number: 8665734
    Abstract: A method and apparatus for providing uplink macro-diversity in packet-switched networks that allows packets and/or portions of packets, e.g., frames, to be selectively sent from an end node, e.g., wireless communication device or mobile terminal, over a set of multiple communication connections, e.g., physical-layer or link-layer connections, to one or more access nodes, e.g., base stations. Uplink macro-diversity is achieved in part through intelligent selective forwarding over multiple communication connections, where the forwarding decision is controlled by the end node based on a variety of factors, e.g., physical-layer channel conditions and/or higher layer policy. The forwarding decision is executed on a rapid timescale, e.g., on a per packet basis, to adapt to the dynamically varying conditions of the set of communication connections.

  • Patent number: 8565801
    Abstract: Improved group communications methods which are well suited for a wireless environment are described. End nodes request that access nodes make changes in group membership information maintained at the access node. The access node responds to the requests by a response signal indicating a grant or denial of the request. Requests may be to add or remove the end node, e.g., a mobile wireless terminal, from a particular group membership list identified in the request signal. The access node maintains a detailed list of group members and uses the information to control how signals, e.g., packets, are transmitted to the group members. Group membership information may be updated at the access node at the time of handoff and/or an end node enters the cell or otherwise changes its point of network attachment.

  • Patent number: 8488602
    Abstract: Group communications methods and apparatus are described. Multiple modes of group communications signaling are supported. In a first mode, copies of packets are separately transmitted to each group member in a sector or cell. In a second mode a copy of a packet is directed to multiple group members at the same time. Transitions between the two modes may be determined as a function of the cost of operating in each of the modes in terms of system cost and/or the number of group members in a cell or sector being serviced by a transmitter.

  • Patent number: 8165124
    Abstract: Methods and apparatus for compressing messages used to support mobile communications are described. After transmission of a first mobile IP message which may be a conventional mobile IP message, a compressed mobile IP message is transmitted. The compressed message includes a new “compressed message” indicator and information which is to replace information in the previous message or to be added to the previous message to construct a new message. In some embodiments, the compressed message includes a mask field, e.g., a sequence of bits, each bit corresponding to one field of a standard registration request message or binding update message. If the mask flag bit corresponding to a field is set, it indicates that the compressed message includes information to replace the content in the corresponding field of the previous message or to be added to the previous message as a field corresponding to the asserted bit.
