Abstract
An embodiment of the present invention relates to a method for transmitting/receiving a signal by a device-to-device (D2D) UE in a wireless communication system, the method comprising the steps of: receiving a discovery signal; and checking a CRC of the discovery signal wherein when at least a part of the CRC is masked by a preconfigured sequence, the UE acquires, from the discovery signal, backhaul link quality information of an apparatus which has transmitted the discovery signal.
Claims8
A method of transmitting and receiving signals, which are transmitted and received by a device-to-device (D2D) user equipment (UE) in a wireless communication system, the method comprising:
- receiving a discovery signal;
- checking a Cyclic Redundancy Check (CRC) of the discovery signal,
- wherein the CRC of the discovery signal includes first bits masked with a synchronization source ID and second bits masked with a predetermined sequence;
- identifying whether the UE that transmitted the discovery signal is a relay UE or a non-relay UE based on the predetermined sequence masked in the second bits;
- and
- obtaining a backhaul link quality information from the discovery signal when the predetermined sequence is a sequence relating to the relay UE.
A device-to-device (D2D) user equipment (UE) in a wireless communication system, comprising:
- a a receiver;
- and
- a processor,
- wherein the processor receives a discovery signal and check a Cyclic Redundancy Check (CRC) of the discovery signal,
- wherein the CRC of the discovery signal includes first bits masked with a synchronization source ID and second bits masked with a predetermined sequence,
- wherein the processor identifies whether the UE that transmitted the discovery signal is a relay UE or a non-relay UE based on the predetermined sequence masked in the second bits, and
- wherein the processor obtains a backhaul link quality information from the discovery signal when the predetermined sequence is a sequence relating to the relay UE.
