Title:
FEEDBACK INFORMATION TRANSMISSION METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/237437
Kind Code:
A1
Abstract:
The present disclosure relates to a feedback information transmission method and apparatus, and a device and a system, belonging to the field of communications. The method comprises: selecting a basic sequence according to an information item of sidelink communication; generating feedback information of the sidelink communication according to the basic sequence; and sending the feedback information to a second terminal. According to the method, a basic sequence is selected by means of an information item of sidelink communication to transmit feedback information in a HARQ transmission mechanism; the selection of the basic sequence is randomized using the information item of the sidelink communication, so as to reduce the probability of selecting and using the same time-frequency resource between user equipments; and an orthogonal basic sequence is used to ensure that the transmission of the feedback information between the user equipments does not generate strong interference.
