1. A sidelink information transmission method, comprising:
sending, by a network device, first indication information to a first communications device, wherein the first indication information indicates a first resource, wherein the first resource is a resource set used to transmit sidelink information, wherein the sidelink information comprises sidelink control information and sidelink data, wherein the first resource comprises at least one time unit in a time domain and further comprises at least one subchannel in a frequency domain, wherein the time unit comprises at least one symbol, wherein the subchannel comprises at least one resource block, and wherein the first indication information indicates a time-domain resource and a frequency-domain resource of a resource that is in the first resource and that is used to transmit the sidelink control information; and
sending, by the network device, first control information to the first communications device, wherein the first control information indicates a second resource, wherein the second resource belongs to the first resource, wherein the second resource comprises a third resource and a fourth resource, wherein the third resource is used by the first communications device to send the sidelink control information to a second communications device, wherein the third resource comprises at least one symbol in the time domain and at least one resource block in the frequency domain, wherein the third resource is indicated by the first indication information, and wherein the fourth resource is used by the first communications device to send the sidelink data to the second communications device based on the sidelink control information.
