Abstract: A redundant system and a redundancy method of a fronthaul network are provided. The redundant system includes a first fronthaul multiplexer. The first fronthaul multiplexer includes a first group port, a second group port, a first cascade port, a first protect port, a first active port, and a first uplink circuit. The first uplink circuit includes a first summation circuit and a second summation circuit. A plurality of input terminals of the first summation circuit are coupled to the first group port and the second group port respectively, and an output terminal of the first summation circuit is coupled to the first protect port. A plurality of input terminals of the second summation circuit are coupled to the first cascade port and the output terminal of the first summation circuit respectively, and an output terminal of the second summation circuit is coupled to the first active port.

Abstract: A delay compensation method and device are provided. The method includes: obtaining a control plane message; obtaining a path delay of each of multiple radio units, and determining a compensation time length corresponding to each of the radio units based on a reference path delay and the path delay of each of the radio units; and sending the control plane message to each of the radio units based on the compensation time length corresponding to each of the radio units.

Abstract: A multiplexer and a method for combining radio frequency (RF) data are provided. The method is described below. The first output management circuit receives first data and second data and determines whether a first power of the first data and a second power of the second data match a default rule. The first output management circuit output first output data including the second data to a combine circuit coupled to the first output management circuit in response to the first power and the second power not matching the default rule. The combine circuit receives multiple output data from the output management circuits respectively and combines the output data to output combined RF data. The output management circuits include the first output management circuit. The output data includes the first output data.
