1. A communication method, comprising:
receiving, by a first terminal device, a plurality of resources;
selecting, by the first terminal device, a resource from the plurality of resources as a first resource for sidelink communication with a second terminal device, wherein the first resource is an unlicensed spectrum resource;
determining, by the first terminal device, whether a quantity of times for which a channel access process, that is also a listen before talk (LBT) process, fails on the first resource is equal to a preset quantity;
in response to determining that the quantity of times for which the channel access process fails on the first resource is equal to the preset quantity, determining, by the first terminal device, first information, wherein the first information includes:
a result of the channel access process, wherein the result indicates that the first terminal device fails to perform the channel access process, and the result further indicates the first resource on which the channel access process fails; and
sending, by the first terminal device, the first information to a network device.
