1. A communication method, wherein the method comprises:
receiving, by a first terminal device, a first message from a second terminal device;
determining, by the first terminal device, a first logical channel corresponding to the first message, wherein the first logical channel comprises a dedicated logical channel, wherein the first message comprises a first parameter, and the first parameter comprises network slice capability information of the second terminal device;
determining, by the first terminal device based on the first logical channel, that the first message is a discovery message, wherein the discovery message indicates that the second terminal device is a relay terminal device; and
determining, by the first terminal device based on the network slice capability information of the second terminal device, that a slice capability of the second terminal device satisfies a slice capability requirement of the first terminal device.
