Title:
METHOD AND DEVICE FOR FEEDING BACK SIDELINK TRANSMISSION STATE
Document Type and Number:
WIPO Patent Application WO/2021/003621
Kind Code:
A1
Abstract:
The present application provides a method for feeding back a sidelink transmission state, comprising: a terminal device obtains an uplink feedback resource, the uplink feedback resource being used for transmitting sidelink feedback information; the terminal device performs sidelink feedback processing. The solution enables a network device to determine the data transmission state on a sidelink. A network device can allocate a retransmission resource to a terminal device after determining that sidelink data transmission fails, thereby improving the sidelink transmission success rate; or the network device does not allocate a retransmission resource to the terminal device any longer after determining that sidelink data transmission succeeds, thereby improving resource utilization.
