Wireless communication enhancements for transparent and boundary clocks

A method at a first node of a wireless communication network, comprising:

• receiving, from a second node of the wireless communication network, a packet data unit (PDU) associated with first and second ethernet frames received at the second node, the first ethernet frame comprising a first precision time protocol (PTP) message, and the second ethernet frame comprising a second PTP message;
• determining an ingress time for the first PTP message received at the second node based at least in part on the PDU;
• and
• determining an adjustment for a timing parameter of the second PTP message based at least in part on the ingress time.

An apparatus, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, at a first node of a wireless communication network, a first ethernet frame comprising a first precision time protocol (PTP) message;
• determine an ingress time for the first PTP message received at the first node;
• receive a second ethernet frame comprising a second PTP message associated with the first PTP message;
• generate a packet data unit (PDU) for transmission to a second node of the wireless communication network based at least in part on the second ethernet frame, the PDU comprising a value corresponding to the ingress time for the first PTP message;
• and
• transmit the PDU to the second node.
