This application provides a scheduling request transmission method and an apparatus. The method includes: configuring, by a network device for a terminal device, a scheduling request (SR) resource carried on an uplink control channel; configuring, by the network device, a mapping relationship between the SR resource and a plurality of available uplink beam pairs for the terminal device; and receiving, by the network device, a scheduling request sent by the terminal device by using the plurality of uplink beam pairs and the corresponding SR resource. According to the scheduling request transmission method and the apparatus that are provided in this application, an SR is sent in a multi-beam communication scenario.
