Problems solved by technology

In another mode, i.e. autonomous resource selection mode, when determining the PSFCH resource, if the PSFCH resource to be used is determined by the receiving end, the sending end needs to perform blind detection on any possible feedback channel resources, and the blind detection complexity increases with The number of blind detections increases; if the PSFCH resource used by the sender is determined, the feedback channel resource may collide with the resources to be used by other user ends, and if the receiver is in half-duplex mode when sending and receiving through the side chain, there will be At the same time, the receiving end cannot send feedback information while receiving information, that is, it cannot send Hybrid Automatic Repeat Request (HARQ, Hybrid Automatic Repeat Request) feedback information, resulting in low HARQ efficiency

Abstract

The present disclosure relates to a channel resource determination method and device, and a storage medium. The method comprises: a second user equipment selecting one PSFCH resource in a specified physical side chain feedback channel (PSFCH) resource set, the PSFCH resource set comprising one or more PSFCH resources; and the second user equipment sending side chain feedback control information (SFCI) according to the selected PSFCH resource. By adopting the method and the device, the probability of resource collision can be effectively reduced, so that the number of times of hybrid automaticrepeat request (HARQ) is reduced, and the HARQ efficiency is improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method, device and storage medium for determining information resources. Background technique [0002] At present, the 80th plenary meeting of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) has passed the 5G New Radio (NR, New Radio) vehicle networking (V2X, Vehicle to Everything) research project. [0003] NR V2X defines two kinds of control information, Sidelink Control Information (SCI, Sidelink Control Information) and Sidelink Feedback Control Information (SFCI, Sidelink Feedback Control Information), where SCI is used to carry demodulated physical sidechain shared channel (PSSCH, The necessary information required by the Physical Sidelink Shared Channel), and the sidechain feedback control information is carried by the Physical Sidelink Feedback Channel (PSFCH, Physical Sidelink Feedback Channel). [0004] In rela...
