Systems and techniques are described for providing optimized vehicle-to-everything (V2X) safety messages over a wide area network (Uu) interface. For example, method for wireless communications may include receiving, by a network device, one or more first messages from one or more vehicles. Each of the first message(s) includes vehicle information associated with a respective vehicle of the vehicle(s). The method may include determining, at the network device, one or more recipient vehicles for one or more second messages based on at least a portion of the vehicle information from the first message(s) and characteristics associated with a respective recipient vehicle of the recipient vehicle(s). The method may include transmitting, at the network device, the second message(s) to the recipient vehicle(s).

Optimized vehicle-to-everything (V2X) messaging

Disclosed are techniques for performing thermal mitigation for one or more devices. For instance, a temperature, humidity, amount of light, and/or other characteristic or factor associated with a vehicle can be obtained. Whether to transition one or more communication functions from the vehicle to a user device can be determined based on the temperature, humidity, etc. In response to a determination to transition the one or more communication functions, the one or more communication functions can be transitioned from a communication unit of the vehicle to a communication unit of the user device.

Thermal mitigation enhancement

Apparatus, methods, and computer-readable media for facilitating a cloud-based vehicle XR user experience are disclosed herein. An example method for wireless communication at a user equipment (UE) includes transmitting a request for a vehicle extended reality (XR) session. The vehicle XR session may be based on a first user XR stream including a vehicle XR component associated with a vehicle and a first user XR component associated with a first user. The first user may have an association with the vehicle. The example method also includes transmitting uplink information associated with the first user XR stream. The example method also includes receiving rendering information associated with the first user XR stream. The rendering information may be based on the uplink information.

Techniques to facilitate a cloud-based vehicle XR experience

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.

Techniques to facilitate LTE CV2X autonomous synchronization

Techniques described herein provide for filtering and prioritizing incoming messages, which can help reduce and smooth out the processing load on components used to process the incoming messages. Filtering techniques may comprise identifying a subset of nearby vehicles from which messages are to be processed, and further calculating remaining delay budgets with regard to the messages to prioritize them for processing. Different techniques for determining a subset of nearby vehicles can be used, and/or remaining delay budgets may be calculated and/or communicated in different ways.

C-V2X message processing timeline adaption based on contouring of remote vehicles and available delay budget

Aspects of the present disclosure describe transmitting data in wireless communications. A set of packets for transmission in a defined sequence can be received where the set of packets includes two or more packets. It can be detected that a packet, of the set of packets, is a prioritized packet type. The packet can be prioritized for transmission ahead of its order in the defined sequence based on the detection of the prioritized packet type. The packet can be transmitted ahead of its order in the defined sequence to an access point.

Prioritizing packets in wireless communications

Aspects directed towards synchronizing out of coverage (OOC) vehicle-to-everything (V2X) communications are disclosed. In one example, a scheduled entity detects a loss of a synchronization signal associated with a V2X communication by detecting when a timing uncertainty value or error value is greater than a threshold value. Packet timing information is then received in response to the loss of the synchronization signal from at least one user equipment (UE) synchronized with the synchronization signal. The scheduled entity then maintains the V2X communication by performing a timing adjustment based on the packet timing information.

In one aspect, the plurality of non-consecutive bursts is transmitted to a DVB-H receiver with a limited memory size for enabling fast channel switching. In one aspect, the channel line-up is presented in an electronic service guide (ESG).

Method and apparatus to enable fast channel switching with limited DVB receiver memory

A UE may receive, via a first communication link that uses a first radio access technology (RAT), information that identifies a threshold associated with a second communication link that uses a second RAT. The UE may monitor one or more communications on the second communication link. The UE may determine whether a parameter associated with the second communication link satisfies the threshold based at least in part on monitoring the one or more communications on the second communication link. The UE may provide a message via the first communication link when the parameter associated with the second communication link satisfies the threshold.

Techniques for managing communication links of a plurality of radio access technologies (RATs)

Certain aspects of the present disclosure relate to methods and apparatus for avoiding conflicts between evolved Multimedia Broadcast Multicast Services (eMBMS) operations and paging and/or mobile originated (MO) operations in communication systems. A method for wireless communications by a user Equipment (UE) is provided. The method generally includes identifying at least one evolved Multimedia Broadcast Multicast Service (eMBMS) session available for receiving one or more eMBMS services from a base station. The method also includes taking one or more actions to reduce a conflict between receiving the one or more eMBMS services from the base station and receiving a paging message from the base station during the eMBMS session. Numerous other aspects are provided.
