Abstract: Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.

Abstract: A conversation augmentation system can automatically augment a conversation with content items based on natural language from the conversation. The conversation augmentation system can select content items to add to the conversation based on determined user “intents” generated using machine learning models. The conversation augmentation system can generate intents for natural language from various sources, such as video chats, audio conversations, textual conversations, virtual reality environments, etc. The conversation augmentation system can identify constraints for mapping the intents to content items or context signals for selecting appropriate content items. In various implementations, the conversation augmentation system can add selected content items to a storyline the conversation describes or can augment a platform in which an unstructured conversation is occurring.

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.

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.

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.

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.

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.

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.
