Abstract
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for determining number of retransmissions of sidelink data in wireless communication system, the method comprising: determining number of retransmissions of sidelink data when the sidelink data is available for transmission; transmitting the sidelink data via direct interface between UEs; and retransmitting the sidelink data as many as the determined number of retransmissions.
Claims12
A method for a user equipment (UE) operating in a wireless communication system, the method comprising:
- determining a number of retransmissions of sidelink data based on a sidelink status with a peer UE;
- transmitting, to the peer UE, the sidelink data via direct interface with the peer UE;
- receiving, from the peer UE, feedback information informing whether to increase or decrease the number of retransmissions;
- adjusting the number of retransmissions based on the feedback information;
- and
- retransmitting the sidelink data based on the number of retransmissions,
- wherein the feedback information is transmitted from the peer UE based on the sidelink status being above one threshold or the sidelink status being below another threshold.
A User Equipment (UE) for operating in a wireless communication system, the UE comprising:
- a Radio Frequency (RF) module;
- and
- a processor operably coupled with the RF module and configured to:
- determine a number of retransmissions of sidelink data based on a sidelink status with a peer UE;
- transmit, to the peer UE, the sidelink data via direct interface with the peer UE;
- receive, from the peer UE, feedback information informing whether to increase or decrease the number of retransmissions;
- adjust the number of retransmissions based on the feedback information;
- and
- retransmit the sidelink data based on the number of retransmissions,
- wherein the feedback information is transmitted from the peer UE based on the sidelink status being above one threshold or the sidelink status being below another threshold.
