Abstract

Disclosed in embodiments of the present application is a feedback information sending method and apparatus. The method comprises: when a terminal device performs sidelink (SL) sending, sending N different feedback information by means of one first interlaced resource block (IRB), wherein N is a positive integer. According to the embodiments of the present application, the N different feedback information is sent by means of the one first IRB; when the terminal device receives multiple PSCCH / PSSCH transmissions, feedback information corresponding to these PSCCH / PSSCH transmissions can be mapped onto the same IRB for transmission, so that multiple feedback information does not need to be transmitted on multiple IRBs any more, thereby avoiding interference and improving the reliability and transmission efficiency of a system.
