Abstract
Official abstract text for this publication.
One embodiment of the present invention relates to a method whereby a device-to-device (D2D) terminal transmits signals in a wireless communication system, the D2D signal transmission method comprising the steps of: determining a resource pool from among resource pools classified in order of priority; determining resources in which to transmit D2D packets by applying the order of priority of the D2D packets to be transmitted in the determined resource pool; and transmitting the D2D packets via the determined resources.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of transmitting a signal, which is transmitted by a D2D (device to device) user equipment in a wireless communication system, comprising the steps of: determining a resource pool from among resource pools classified according to a priority; determining a resource for transmitting a D2D packet by applying a priority of the D2D packet to the determined resource pool; and transmitting the D2D packet through the determined resource. 2 . The method of claim 1 , wherein a TRP (time resource pattern) is used when the resource for transmitting the D2D packet is determined. 3 . The method of claim 2 , wherein the TRP is contained in a TRP subset which is classified according to the priority of the D2D packet. 4 . The method of claim 2 , wherein the TRP corresponds to a bitmap indicating a subframe in which transmission of a D2D signal is permitted. 5 . The method of claim 2 , wherein if the priority of the D2D packet is greater, a TRP containing more 1's is used. 6 . The method of claim 5 , wherein if the TRP containing more 1's is used, the number of repetitive transmission per MAC PDU (medium access layer protocol data unit) increases as well. 7 . The method of claim 1 , wherein if the D2D packet corresponds to an MCPTT (mission critical push to talk) packet, the D2D packet has a highest priority. 8 . A user equipment transmitting a D2D (device to device) signal in a wireless communication system, comprising: a transmitter and a receiver; and a processor, the processor configured to determine a resource pool from among resource pools classified according to a priority, the processor configured to determine a resource for transmitting a D2D packet by applying a priority of the D2D packet to the determined resource pool, the processor configured to transmit the D2D packet through the determined resource. 9 . The D2D user equipment of claim 8 , wherein a TRP (time resource pattern) is used when the resource for transmitting the D2D packet is determined. 10 . The D2D user equipment of claim 9 , wherein the TRP is contained in a TRP subset which is classified according to the priority of the D2D packet. 11 . The D2D user equipment of claim 9 , wherein the TRP corresponds to a bitmap indicating a subframe in which transmission of a D2D signal is permitted. 12 . The D2D user equipment of claim 9 , wherein if the priority of the D2D packet is higher, a TRP containing more 1's is used. 13 . The D2D user equipment of claim 12 , if the TRP containing more 1's is used, the number of repetitive transmission per MAC PDU (medium access layer protocol data unit) increases as well. 14 . The D2D user equipment of claim 8 , wherein if the D2D packet corresponds to an MCPTT (mission critical push to talk) packet, the D2D packet has a highest priority.
