Aspects relate to sidelink transmissions directed towards vehicle-to-everything (V2X) applications. A UE may determine an application-layer capability of the UE in which the application-layer capability corresponds to a V2X application implemented on the UE, and transmit an announcement including an indication of the application-layer capability via a transceiver. A UE may also receive an announcement via a transceiver that includes an indication of an application-layer capability corresponding to a second UE in which the application-layer capability corresponds to a V2X application implemented on the second UE, and engage with the second UE via the V2X application.

Announcement of vehicle-to-everything capabilities

Mechanisms for performing unicast packet addressing and communication, e.g., in a C-V2X sidelink communication scenario, are provided. In one aspect, a method for wireless communication performed by a first wireless communication device includes receiving a source identifier associated with a second wireless communication device, and determining, based on the source identifier associated with the second wireless communication device and a deterministic function, a destination identifier. The destination identifier is different from the source identifier. The method further includes generating a packet comprising the destination identifier, where the destination identifier indicates a unicast packet, and transmitting the unicast packet to the second wireless communication device.

Unicast packet addressing and communication

Apparatus, methods, and computer-readable media for facilitating identifier-based transport types of a GNLP are disclosed herein. An example method for wireless communication at a transmitting UE includes receiving a message based on a GNLP, the message including a GNLP header. The example method also includes populating the GNLP header to indicate that the message is associated with a single-hop transport type, the single-hop transport type including a unicast message, a groupcast message, or a broadcast message. The example method also includes transmitting the message via sidelink to a receiving UE. An example method for wireless communication at a receiving UE includes receiving, from a transmitting UE, a message via sidelink, the message based on a GNLP and including a GNLP header. The example method also includes using the GNLP header to determine that the message is associated with a single-hop transport type.

Techniques to facilitate V2X identifier-based transport types of a geographical network layer protocol

The claimed subject matter relates to systems and methods for processing messages in a wireless communications environment. In an aspect, a communications method is provided. The method includes initiating a registration with a network domain node and generating sequence information with respect to the registration. The sequence information is then employed to facilitate further communications with the network domain node.

Message ordering for network based mobility management systems

A configuration to allow for the suppression or delay of the changing of an ID of a first wireless device to maintain a connection with another wireless device. The apparatus establishes a connection with a second wireless device using a side link. An ID of a first wireless device is provided to the second wireless device. The apparatus determines to change the ID of the first wireless device based on a predetermined schedule. The apparatus initiates a suppression to change of the ID of the first wireless device to maintain the connection with the second wireless device.

V2X ID management for persistent connection

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured for contention-based forwarding (CBF) to relay a message toward a destination. The UE may receive signaling indicating a configuration for CBF. The CBF configuration may be associated with a maximum communication range for CBF signaling. The UE may receive a message to relay toward the destination using CBF. The message may include a first indication of a dynamic communication range for the CBF which may be less than or equal to the maximum communication range. The UE may determine a timer value to retransmit the message based on the dynamic communication range. When a timer set to the timer value expires, the UE may retransmit the message to nearby stations and include an indication of the dynamic communication range with the message.

Techniques for dynamic distance control for contention-based forwarding

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish connectivity to a local area network using cellular radio access technology (RAT). The UE may establish a signaling radio link with a cellular access node (AN) via a cellular RAT. The UE may transmit a connectivity request to a network node via the signaling radio link. The connectivity request may specify a connectivity type for establishing connectivity to a LAN. Based at least in part on an acceptance of the connectivity request, the UE may establish a data radio link with the cellular AN. In an example, the acceptance of the connectivity request may include at least one parameter for configuring the connectivity to the LAN. The UE may then establish a data flow for exchanging data link layer packets with the LAN via the data radio link.

Connectivity to a local area network via a cellular radio access technology

A user equipment (UE) may experience poor communication with a network access device, and the network access device may configure the UE to connect to, and route communications through, one or more relay nodes (e.g., which may be another UE, a network operator-deployed relay, etc.). Techniques are described whereby these relay nodes may autonomously form a wireless backhaul network. Sequential implementations are considered such that the size of the wireless backhaul network may scale efficiently. In some examples, the wireless backhaul network may form by reusing existing connectivity establishment procedures. Importantly, the proposed techniques enable a relay to possess (e.g., be configured with) functionality that may traditionally be associated with a UE, base station, and gateway. Such multi-faceted functionality may enable the described sequential formation of wireless backhaul networks with tree topology.

Autonomous formation for backhaul networks

Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.

Enhanced techniques for using core based nodes for state transfer

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish a packet data network (PDN)-connectivity session to a PDN using a cellular radio access technology (RAT) and migrate the PDN-connectivity session from a source access node (AN) to a target AN. Migration may initiate when a decision to perform a handover is made. The target AN may receive a network address and information about a first data radio link established between the UE and source AN. The target AN may establish a second data radio link with the UE based at least in part on the first data radio link information, and may transmit, to the PDN, a path update including the network address and an updated path via the target AN. In some cases, the target AN may forward packets between the UE and the PDN via the second data radio link.

Migration of local gateway function in cellular networks

Methods, systems, and devices for wireless communication are described. A serving base station may determine a handover loss metric associated with a UE that is a candidate for handover. The handover loss metric may be based on connection parameters associated with the serving base station and a target base station, respectively. The serving base station may identify, based on the handover loss metric, a type of handover procedure to perform. The serving base station may perform the handover procedure of the UE to the target base station according to the identified handover type.

Techniques for transmission control protocol aware handover type determination

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a first node. The first node receives a first packet from a second node. The first node determines that the first packet is a query packet requesting a response packet and associated with a first transaction. The first node determines that the first node is a first next hop node associated with the first packet. The first node determines that the query packet includes an indication for a local exploration. The first node delays further routing the first packet.
