METHOD AND APPARATUS FOR ACQUIRING TIME SYNCHRONIZATION IN WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus for acquiring time synchronization in a wireless communication system is provided. In a convergence system of a cellular system and a Wi-Fi system, when a user equipment (UE) can perform uplink (UL) transmission to a evolved NodeB (eNB) of the cellular system but cannot perform DL reception from the eNB, the eNB acquires a time synchronization based on a first timing advance (TA) between the eNB and an access point (AP) of the Wi-Fi system, and a second TA between the AP and the UE.
