Problems solved by technology

However, the reason why the data sender did not receive ACK or NACK may be that the data receiver did not detect the data, or it may be that the feedback information transmission failed, or it may be the geographical distance between the data sender and the data receiver. The distance exceeds the QoS communication distance
For the data sender, it is not possible to determine the reason why neither ACK nor NACK is received, so it is likely to resend data without resending data, resulting in waste of resources

Embodiment Construction

[0094] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0095] The feedback method provided by the embodiments of the present disclosure can be applied to a communication scenario of direct communication between two devices, such as a vehicle-to-other node (V2X) vehicle wireless communication scenario, and the like. Among them, V represents the on-board device, and X represents any object that interacts with the on-board device. Currently X mainly i...

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...
