Abstract

The present disclosure relates to a feedback method, apparatus, and storage medium, in which a geographical distance between a data receiving end and a data transmitting end is determined to exceed aquality of service (QoS) communication distance; and sending out the out-of-range feedback information, wherein the out-of-range feedback information is used for representing that the geographic distance between the data receiving end and the data sending end exceeds the QoS communication distance. And detecting the out-of-range feedback information, and determining whether to retransmit the dataaccording to the detection result of the out-of-range feedback information. By the method and the device, the fact that the geographic distance between the data receiving end and the data sending endexceeds the QoS communication distance can be determined, the probability of occurrence of the phenomenon that data are retransmitted under the condition that the data are not required to be retransmitted can be reduced, and resource waste is avoided.

Description

technical field

[0001] The present disclosure relates to the technical field of communication, and in particular to a feedback method, device and storage medium. Background technique

[0002] Recently, with the development of technologies such as automatic driving, in order to support new vehicle wireless communication technology (Vehicle to Everything, V2X) services, new requirements are put forward for the performance of V2X technology. Using 5G technology to support new V2x communication services and scenarios has been planned by 3GPP as an important content of Rel16.

[0003] In the new radio (New Radio, NR) V2X technology, the unicast and multicast services of direct communication support the use of a physical layer hybrid automatic repeat request (Hybrid automatic repeat request, HARQ) feedback retransmission mechanism. For unicast services, the data receiving end feeds back an acknowledgment (Acknowledgment, ACK) when the data is correctly received (correctly decoded...
