Title:
METHODS FOR COMMUNICATION, DEVICES, AND COMPUTER READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/243966
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a solution for resource reservation for a retransmission in a sidelink channel. In a method for communication, a first device generates data to be transmitted to a second device via a sidelink channel. The first device determines whether a reservation criterion for reserving a retransmission resource for a retransmission of the data is satisfied. The retransmission resource is comprised in a resource pool for sidelink communications of the first device and further devices including the second device. In response to determining that the reservation criterion is satisfied, the first device transmits to the further devices reservation information indicating that the retransmission resource is reserved. With the embodiments of the present disclosure, better resource utilization of a resource pool for sidelink communications enabling resource reservation for feedback based retransmission is achieved.
