METHOD FOR DETECTING SEARCH SIGNAL FOR DEVICE-TO-DEVICE (D2D) COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
First Claim
1. A method for detecting a discovery signal for device-to-device (D2D) communication by a first user equipment (UE) in a wireless communication system, the method comprising:
- receiving the discovery signal from second UEs; and
acquiring control information for D2D communication by performing blind decoding of the discovery signal,wherein a search space for blind decoding includes at least one virtual resource block (VRB) set configured based on a plurality of physical resource block sets predefined to allocate the discovery signal.

Abstract
The present invention relates to a method for detecting a search signal of a first terminal for device-to-device (D2D) communication in a wireless communication system. Specifically, the method comprises the steps of: receiving search signals from second terminals; and obtaining control information for D2D communication by carrying out blind decoding of the search signals, wherein a search space for the blind decoding consists of at least one virtual resource block (VRB) set configured on the basis of multiple physical resource block sets which are predefined such that the search signals are assigned thereto.

9. A method for detecting a discovery signal for device-to-device (D2D) communication by a first user equipment (UE) in a wireless communication system, the method comprising:
-
receiving a discovery signal from second UEs; and acquiring control information for D2D communication by performing blind decoding of the discovery signal, wherein a search space for blind decoding is determined based on the number of discovery resource units (DRUs) per discovery subframe (DSF) and the number of reference resource candidates per DRU, and wherein at least one of the number of DRUs per DSF and the number of reference signal resource candidates per DRU is determined based on system bandwidth for D2D communication.
