A communication processing method, wherein the method comprises: determining, by a first terminal device, that a priority of a first resource is lower than a priority of a third resource when a second condition is met; determining, by the first terminal device, to release the first resource; generating, by the first terminal device, first information; and sending, by the first terminal device, the first information to a network device, wherein the first information is used to indicate any one or more of the following content: information indicating that the first terminal device releases a first resource; the first resource released by the first terminal device; and information indicating that the first terminal device requests a second resource from the network device; wherein the first resource comprises any one or more of the following content: a resource of a sidelink, wherein the sidelink is a wireless direct communication link between the first terminal device and a second terminal device, a resource of an uplink, wherein the resource of the uplink is the resource of the uplink between the first terminal device and the network device, a resource of a downlink, wherein the resource of the downlink is the resource of the downlink between the first terminal device and the network device; and wherein the third resource comprises a second-mode resource of the sidelink. determining, by a first terminal device, that a priority of a first resource is lower than a priority of a third resource when a second condition is met; determining, by the first terminal device, to release the first resource; generating, by the first terminal device, first information; and sending, by the first terminal device, the first information to a network device, wherein the first information is used to indicate any one or more of the following content: information indicating that the first terminal device releases a first resource; the first resource released by the first terminal device; and information indicating that the first terminal device requests a second resource from the network device; wherein information indicating that the first terminal device releases a first resource; the first resource released by the first terminal device; and information indicating that the first terminal device requests a second resource from the network device; wherein the first resource comprises any one or more of the following content: a resource of a sidelink, wherein the sidelink is a wireless direct communication link between the first terminal device and a second terminal device, a resource of an uplink, wherein the resource of the uplink is the resource of the uplink between the first terminal device and the network device, a resource of a downlink, wherein the resource of the downlink is the resource of the downlink between the first terminal device and the network device; and wherein the third resource comprises a second-mode resource of the sidelink. a resource of a sidelink, wherein the sidelink is a wireless direct communication link between the first terminal device and a second terminal device, a resource of an uplink, wherein the resource of the uplink is the resource of the uplink between the first terminal device and the network device, a resource of a downlink, wherein the resource of the downlink is the resource of the downlink between the first terminal device and the network device; and wherein the third resource comprises a second-mode resource of the sidelink.
