Title:
METHODS FOR SIDELINK COMMUNICATION, TERMINAL DEVICE, AND COMPUTER READABLE MEDIA
Document Type and Number:
WIPO Patent Application WO/2022/133771
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a solution for sidelink communications. In a method for communications, in accordance with a determination that a communication between a first terminal device and a second terminal device is in a power saving mode, the first terminal device determines a first candidate resource set from a resource pool for the first terminal device. The first candidate resource set is mapped to a first feedback occasion for the second terminal device. The first terminal device transmits, to the second terminal device, first data on a first resource of the first candidate resource set. The first terminal device then receives, from the second terminal device, a first feedback message to the first data during the first feedback occasion. Embodiments of the present disclosure provide a sidelink feedback mechanism on the PSFCH, which is especially friendly to power saving terminal devices. With the proposed feedback mechanism, a tradeoff between the power consumption and the time sensitive requirements of the terminal devices can be achieved, while the conflict of power selection in the sidelink resource pool can be avoided.
