Abstract: Methods, systems, and devices for wireless communications are described. In an example ingress point of a wireless communication network, a method includes receiving a first ethernet frame comprising a precision time protocol (PTP) message at a first node and determining an ingress time for the PTP message, generating a packet data unit (PDU) for transmission to a second node of the wireless communication network based at least in part on the first ethernet frame by overwriting a field in the PTP message with a value corresponding to the ingress time, and sending the PDU to the second node. An egress point method may include receiving a PDU comprising a PTP message, determining an ingress time from a field in the PTP message overwritten with a value corresponding to the ingress time, and determining an adjustment for a timing parameter based at least in part on the ingress time.

Abstract: Methods, systems, and devices for wireless communications are described. An access node may schedule traffic with different levels of priority for communications with a user equipment. The access node may receive a time-sensitive networking time-aware schedule from a first interface via an Ethernet frame that defines a set of periodic time intervals reserved for transmitting traffic with a high-priority (e.g., hard-real time traffic). In some cases, one or more frequency resources may additionally be reserved for the high-priority traffic. Accordingly, during the reserved time intervals, if the high-priority traffic is present, the access node may transmit the high-priority traffic on the reserved frequency resource(s). Outside the reserved time intervals, the access node may schedule lower-priority traffic on the reserved frequency resource(s) in addition to the other resources.

Another example at a node includes receiving, from additional nodes of the wireless communication network, indicators of one or more timing domains supported by the additional nodes, receiving a PTP message associated with a timing domain, and sending the PTP message to a subset of the additional nodes based at least in a part on the indicators of one or more timing domains supported by the additional nodes.

Abstract: Generally, the described techniques provide for a device determining or receiving signaling including a packet delivery time window configuration that indicates delivery windows within which transmissions may be held and/or delivery opportunities within which communications are expected to be transmitted. For example, the device may identify a packet delivery time window configuration for communications with another device.

Based on the identified packet delivery time window configuration, the device may delay transmission of the data packet (e.g., for the duration of one or more configured delivery windows). At, for example, the end of the respective delivery window, the device may deliver the data packet to a network device for which the information of the data packet is to be used.
