Abstract: Systems and techniques are provided for path tracing. 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.

Abstract: Methods, systems, and devices for wireless communication are described. 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.

Abstract: A user equipment device (UE) initiates the creation of a dedicated bearer between a local gateway (L-GW) and a packet data network gateway (P-GW). A GTP tunnel is established to connect the L-GW, a serving gateway (S-GW), and the P-GW. The L-GW and P-GW apply Network Address Translation (NAT) and/or Traffic Flow Template (TFT) to route the traffic between the LS and a Service Capacity Server/Application Server (SCS/AS). Alternatively, an SCS-initiates the bearer creation, and an SCEF manages the creation of the GTP tunnel connection. The L-GW may be co-located with an Evolved UTRAN Node B (eNB) and/or connected to multiple eNBs which are not co-located with the L-GW.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. More particularly, various aspects relate generally to power boosting a channel state information reference signal (CSI-RS) in a CSI-RS resource occasion occurring in a sub-band full duplex (SBFD) set of symbols and/or in a CSI-RS resource occasion that overlaps with an uplink sub-band and/or a guard band of the SBFD set of symbols.

The network node may transmit, and the UE may receive, in an instance of the CSI-RS resource that occurs in an SBFD set of symbols, a CSI-RS. The CSI-RS may be associated with a power-boosted energy per resource element (EPRE) as compared to an EPRE of a CSI-RS transmitted in a CSI-RS occasion occurring in a non-SBFD set of symbols.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may apply an uplink muting maximum power reduction (UM-MPR) to uplink transmissions based on receiving an activation for uplink muting (e.g., activation of a muting pattern). The UE may apply the UM-MPR to an uplink transmission associated with a first muting pattern based on the first muting pattern being from a set of muting patterns, or from a subset of the set of muting patterns. In some examples, the UE may identify a value of the UM-MPR for the uplink transmission based on the first uplink muting pattern applied to the uplink transmission, a waveform type of the uplink transmission, a modulation scheme of the uplink transmission, a type of uplink resource allocation of the uplink transmission, or any combination thereof.
