WIRELESS COMMUNICATION DEVICE AND METHOD THEREIN FOR TIME SYNCHRONIZATION IN A WIRELESS COMMUNICATION NETWORK

摘要

A wireless communication device and method therein for time synchronization in a wireless communication network are disclosed. The wireless communication device determines a first timing (tc) by performing a coarse time synchronization based on a synchronization signal received by the wireless communication device, wherein the received synchronization signal is sampled either in an original sampling rate or a reduced sampling rate. The wireless communication device determines a second timing (tf) by performing a fine time synchronization based on the determined first timing (tc) and the received synchronization signal.
