Techniques for synchronizing a clock of a wired connection when transmitted over a wireless channel

An apparatus for wireless communication, comprising:

• a frequency measurement module configured to measure a frequency of a source clock signal generated by the apparatus, wherein the measurement of the frequency is performed using a first reference clock signal, wherein the frequency measurement module is further configured to generate a frequency-stamp message including at least in part the measured frequency;
• a packetizer configured to encapsulate the frequency-stamp message in at least one packet, wherein the frequency-stamp message indicates the frequency of the source clock as a function of a frequency of the first reference clock signal;
• and
• a wireless transmitter configured to transmit the at least one packet to another device over a wireless channel.

An apparatus for wireless communication, comprising:

• a de-packetizer configured to extract a frequency-stamp and a time-stamp from at least one packet received from a device;
• a frequency setting unit configured to determine a frequency value based on the frequency-stamp;
• and
• a clock generation unit comprising a phase-locked loop (PLL), wherein the clock generation unit is configured to:
• synthetize a sink clock signal using the determined frequency value and a reference clock signal during a locking phase of the PLL;
• and
• synthetize the sink clock signal using the time-stamp during a tracking phase of the PLL.

A method, performed by a device, for wireless communication, comprising:

• receiving at least one packet from another device;
• extracting a frequency-stamp and a time-stamp generated by the other device from at least one packet received from the other device;
• determining a frequency value based on the frequency-stamp;
• synthetizing a sink clock signal using the determined frequency value and a reference clock signal during a locking phase of a phase-locked loop (PLL);
• and
• synthetizing the sink clock signal using the time-stamp during a tracking phase of the PLL.
