Abstract
One embodiment of the present invention relates to a method for a device-to-device (D2D) user equipment to transmit a discovery signal in a wireless communication system, the method comprising the steps of: choosing a resource pool from among one or more resource pools; and transmitting a discovery signal by using the resources of the chosen resource pool, wherein the resource pool is chosen on the basis of RSRP measurement results.
Claims9
A method for transmitting a discovery signal by a Device-to-Device (D2D) terminal in a wireless communication system, the method comprising:
- selecting, by the D2D terminal, a resource pool from among resource pools configured by a network according to a Reference Signal Received Power (RSRP) measurement result for a signal of the network at the D2D terminal, wherein a RSRP range configured for the resource pools is signaled through a Radio Resource Control (RRC) signaling from the network;
- determining, by the D2D terminal, resources to repeatedly transmit a discovery signal within the selected resource pool by applying a hopping pattern;
- and
- repeatedly transmitting, by the D2D terminal, the discovery signal using the determined resources.
A Device-to-Device (D2D) terminal for transmitting a discovery signal in a wireless communication system, the D2D terminal comprising:
- a transceiver;
- and
- a processor,
- wherein the processor is configured to:
- select a resource pool from among resource pools configured by a network according to a Reference Signal Received Power (RSRP) measurement result for a signal of the network at the D2D terminal, wherein a RSRP range configured for the resource pools is signaled through a Radio Resource Control (RRC) signaling from the network;
- determine resources to repeatedly transmit a discovery signal within the selected resource pool by applying a hopping pattern;
- and
- control the transceiver to repeatedly transmit the discovery signal using the determined resources.
