Abstract
A method is proposed for maintaining uplink synchronization with P2P communication in wireless communication networks, comprising steps of: the wireless communication system overhears the P2P communication between two UEs (user equipments), determines the SS (synchronization shift) information of said UEs according to the overheard information transferred by each UE in P2P communication, and transmits the SS information to the corresponding UE via the downlink common control channel; the UE monitors the downlink common control channel, and adjusts the TA (timing advance) for transmitting signals according to the SS information transferred via the downlink common control channel.
