Abstract: A communication system comprises a clock generator configured to generate a plurality of system clock signals used to synchronize components included in each of communication nodes in the communication system based on an external clock signal provided by an external clock source located outside the communication system and a physical layer configured to transmit any one of the generated system clock signals to a small cell communicatively connected to an end communication node of the communication system.

Abstract: A synchronization method of a communication network, the synchronization method comprises monitoring a connection state of second communication nodes that are synchronized using a synchronization signal provided through a first communication node to which a synchronization source is connected, determining whether the number of the connected second communication nodes exceeds a reference value according to a result of the monitoring and switching a synchronization mode of at least one second communication node when the number of the second communication nodes exceeds a reference value.
