Method and apparatus of performing a discovery procedure

摘要

The present invention is directed to a method and an apparatus for use in a wireless communication system. Specifically, the present invention is directed to a method of performing a discovery procedure for a ProSe and an apparatus therefore, in which the method comprises: receiving first resource allocation information for plural ProSe channels from a base station via a broadcast signal; sensing the plural ProSe channels; transmitting a sensing result for the plural ProSe channels to the base station; receiving second resource allocation information indicating one of the plural ProSe channels from the base station via a unicast signal; and transmitting a discovery signal via the ProSe channel indicated by the second resource allocation information.

1. A method of performing a discovery procedure for a Proximity-Based Service (ProSe) by a User Equipment (UE) in a cellular communication system, the method comprising:
receiving first resource allocation information for plural ProSe channels from a base station via a broadcast signal; sensing one of the plural ProSe channels, the one of the plural ProSe channels being identified using least significant bits of a ProSe service identity (ID); transmitting a sensing result for one of the plural ProSe channels to the base station, when the one of the plural ProSe channels is detected as being idle and if the UE is within a coverage of the cellular network system; and transmitting a discovery signal via the one of the plural ProSe information channels to another UE, when the one of the plural ProSe channels is detected as being idle and if the UE is out of the coverage of the cellular network system.
