UE discovery method and system in D2D network
First Claim
1. A method of a user equipment (UE) in a wireless communication network, the method comprising:
- selecting a synchronization reference UE;
identifying pre-configuration information for transmitting a synchronization signal; and
transmitting the synchronization signal in a subframe selected based on the pre-configuration information,wherein the pre-configuration information comprises a list of resource pools for a sidelink communication, andwherein a sidelink synchronization signal identity (SLSSID) of the synchronization signal is selected to be the same as a SLSSID of the selected synchronization reference UE.

Abstract
A 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as long-term evolution (LTE) is provided, including a method for performing device to device (D2D) discovery by a user equipment (UE), which is out of the coverage area serviced by a base station, in a wireless communication network. The method includes the operations of receiving pre-configuration information for transmitting a discovery message, and transmitting the discovery message in a transmission resource determined on the basis of the pre-configuration information, wherein the pre-configuration information includes a list of pools for transmitting the discovery message, and the transmission resource is determined from the list of pools.
