D2D operation method of terminal in wireless communication system and terminal using method
The present invention provides a method by which a relay terminal determines priority in a wireless communication system including a base station, the relay terminal, and a remote terminal, the method comprising: acquiring remote terminal related information; acquiring the remote terminal related information, and then determining the priority between pieces of the remote terminal related information and the priority between the remote terminal related information and relay terminal related information; and transmitting the information on the basis of the priority, wherein the relay terminal transmits, on the basis of the priority determined by the relay terminal, the information by applying different physical channel parameters.
1. A method for transmitting remote user equipment (UE) related information or relay UE related information in a wireless communication system including a base station (BS), a relay UE, and a remote UE, the method performed by the relay UE and comprising:
receiving, from the remote UE, the remote UE related information;
transmitting, to the BS, the remote UE related information or the relay UE related information based on comparing a priority of the remote UE related information and a priority of the relay UE related information after receiving the remote UE related information,
wherein the relay UE performs a transmission by applying different physical channel parameters based on the priority of the remote UE related information and the priority of the relay UE related information, and
wherein, based on the remote UE related information being wide area network (WAN) communication related control information or WAN communication related feedback information and the relay UE relate information being WAN communication related data information, the priority of the remote UE related information is higher than the priority of the relay UE related information and the relay UE transmits the WAN communication related control information of the remote UE or the WAN communication related feedback information of the remote UE to the BS.
2. The method of claim 1 , wherein
the remote UE is a UE having communication capability of a limited size band.
3. A relay user equipment (UE) in a wireless communication system including a base station (BS), the relay UE, and a remote UE, wherein the relay UE comprises:
a transceiver transmitting and receiving a wireless signal; and
a processor coupled to the transceiver,
wherein the processor is configured to:
control the transceiver to receive, from the remote UE, remote UE related information; and
control the transceiver to transmit, to the BS, the remote UE related information or relay UE related information based on comparing a priority of the remote UE related information and a priority of the relay UE related information after receiving the remote UE related information,
wherein the relay UE performs a transmission by applying different physical channel parameters based on the priority of the remote UE related information and the priority of the relay UE related information, and
wherein, based on the remote UE related information being wide area network (WAN) communication related control information or WAN communication related feedback information and the relay UE relate information being WAN communication related data information, the priority of the remote UE related information is higher than the priority of the relay UE related information and the relay UE transmits the WAN communication related control information of the remote UE or the WAN communication related feedback information of the remote UE to the BS.
