Abstract
Provided is a method for transmitting resource information for device-to-device (D2D) communication of a D2D transmission terminal in a wireless communication system, the method being characterized by comprising the steps of: receiving a resource pool configuration for D2D communication; and transmitting, to a D2D reception terminal, resource information therefor indicating the resource for a first D2D signal transmission to the D2D transmission terminal.
Claims8
A method of transmitting resource information for device-to-device (D2D) communication in a wireless communication system, the method performed by a D2D transmission user equipment (UE) and comprising:
- receiving a resource pool configuration for the D2D communication;
- transmitting, to a D2D reception UE, resource information including a time resource pattern (T-RPT) indicating resources for a first D2D signal transmission from the D2D reception UE to the D2D transmission UE;
- and
- configuring to determine the D2D transmission UE as a heavy transmission (HTX) D2D UE when an amount of information to be transmitted by the D2D transmission UE is greater than a threshold value,
- wherein if the D2D transmission UE is not determined as the HTX D2D UE, resources indicated by the T-RPT are used for D2D signal transmission,
- wherein if the D2D transmission UE is determined as the HTX D2D UE, odd-numbered resources indicated by the T-RPT are used for D2D signal transmission, and even-numbered resources indicated by the T-RPT are used for D2D signal reception,
- wherein the resource information indicates first radio resources for the first D2D signal transmission,
- wherein the first radio resources are configured in a resource pool excluding second radio resources, and
- wherein the second radio resources are radio resources used for a second D2D signal transmission from the D2D transmission UE to the D2D reception UE.
A device-to-device (D2D) transmission user equipment (UE) for transmitting resource information for D2D communication in a wireless communication system, the D2D transmission UE comprising:
- a transmitter and a receiver;
- and
- a processor,
- wherein the processor is configured to:
- receive a resource pool configuration for the D2D communication;
- transmit, to a D2D reception UE, resource information including a time resource pattern (T-RPT) indicating resources for a first D2D signal transmission from the D2D reception UE to the D2D transmission UE;
- and
- configure to determine the D2D transmission UE as a heavy transmission (HTX) D2D UE when an amount of information to be transmitted by the D2D transmission UE is greater than a threshold value,
- wherein if the D2D transmission UE is not determined as the HTX D2D UE, resources indicated by the T-RPT are used for D2D signal transmission,
- wherein if the D2D transmission UE is determined as the HTX D2D UE, odd-numbered resources indicated by the T-RPT are used for D2D signal transmission, and even-numbered resources indicated by the T-RPT are used for D2D signal reception,
- wherein the resource information indicates first radio resources for the first D2D signal transmission,
- wherein the first radio resources are configured in a resource pool excluding second radio resources, and
- wherein the second radio resources are radio resources used for a second D2D signal transmission from the D2D transmission UE to the D2D reception UE.
