Abstract
According to one aspect of the teachings herein, a method and apparatus predict a departure time of transmit data transmitted from a first network entity to a second network entity, determine a timing difference between a detected departure time and the predicted departure time of the transmit data that is was based on an estimated path delay of data transmission circuitry, and indicate the timing difference in further transmit data, e.g., to improve synchronization at the second network entity. In one or more embodiments, the timing difference is further used to compensate one or more timing operations at the first network entity, such as adapting one or more prediction parameters used by a departure-time prediction process.
