For example, a process can include establishing a path tracing session associated with path tracing (PT) probe packets from a PT source node of an IPv6 network fabric. A PT probe packet can be received with a first IPv6 Destination Options Header with Path Tracing Option (DOH-PT) header that encodes path tracing information of the PT source node and indicates respective path tracing information for each PT midpoint node along a path from the PT source node to a PT sink node of the IPv6 network fabric. The received PT probe packet can be updated to include a second DOH-PT header that encodes path tracing information of the PT sink node. An updated PT probe packet includes the first and second DOH-PT headers and can be encapsulated with an additional IPv6 header corresponding to forwarding information of a collector node.

A communication device, such as a network entity may determine a set of topologies associated with a non-linear distortion characteristic of a wireless communication at a set of devices (e.g., a user equipment (UE), a base station). For example, a single waveform may have different distortion characteristics on different frequencies. Each of one or more topologies of the set of topologies may include a frequency spectrum mask for the wireless communication. The wireless communication may include a waveform at a first frequency. The frequency spectrum mask associated with the non-linear distortion characteristic of the waveform at the first frequency may be for interference mitigation at a second frequency different than the first frequency. The network entity may transmit first control signaling indicating the set of topologies associated with the non-linear distortion characteristic of the waveform.

The data is encoded efficiently into arrays of fixed-size data blocks using a data format which can be directly consumed for ray traversal or rasterization. Vertex data in a block is pre-quantized and stored using a fixed-bit quantization grid. Mesh connectivity is encoded using a triangle strips based on control values representing triangle interconnectivity, and a compressed index buffer storing indices for vertices in each strip. Further, triangle identifiers are derived from the triangle's position in the strip. The block can further store geometry identifiers and opacity maps corresponding to primitive data.
