Title:
METHOD AND DEVICE FOR TRANSMITTING SIDELINK DATA TO RECEPTION TERMINAL IN SIDELINK DRX OPERATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/043242
Kind Code:
A1
Abstract:
According to various embodiments of the present disclosure, provided is a method performed by a first terminal in order to transmit SL data to a second terminal in a sidelink discontinuous reception (SL DRX) operation in a wireless communication system, the method comprising the steps of: identifying a first trigger of a buffer status report (BSR) based on available SL data; identifying a second trigger of a scheduling request (SR) based on the first trigger of the BSR; determining a DRX active time of the second terminal for the triggered BSR based on the triggered SR; and when the DRX active time of the second terminal exists within a packet delay budget (PDB) requirement for resources to be allocated on the basis of the transmission of the triggered BSR and the transmission of the triggered SR, transmitting the triggered SR to a base station, or, when the DRX active time of the second terminal does not exist within the PDB requirement for the resources to be allocated on the basis of the transmission of the triggered BSR and the transmission of the triggered SR, cancelling the transmission of the triggered SR.
