Abstract

Communication between a Radio Equipment Control (REC) and a Radio Equipment (RE) in a wireless network uses a Common Public Radio Interface connection. When the Radio Equipment Control and the Radio Equipment are located remote from each other, and are connected by an asymmetric transport network, such as an Optical Transport Network, path delay data is transmitted in the Common Public Radio Interface data frames. This allows the CPRI end nodes to correct for path delay asymmetry using the path delay data.
