A communications method and apparatus are provided. The method includes: receiving, by a terminal device, a first message from a network device, where the first message includes first offset information, or the first message includes second offset information, or the first message includes the first offset information and the second offset information; the first offset information is used to indicate a time offset value of a random access response RAR monitoring window for monitoring a RAR; and the second offset information is used to indicate a time offset value for sending a second message, and the second message is a message sent by the terminal device based on the RAR; and randomly accessing, by the terminal device, the network device based on the first message.

Monitoring random access response

When a first sidelink channel state information CSI report is triggered, a first terminal obtains a first sidelink resource configured by a base station for the first terminal, where the first sidelink resource can be used to transmit the sidelink CSI report. The first terminal sends the first sidelink CSI report to a second terminal on the first sidelink resource, where the first sidelink CSI report is used to feed back CSI of a sidelink between the first terminal and the second terminal.

Method, apparatus, and system for sending sidelink channel state information report

According to the method, when the first terminal determines that the first terminal does not receive the acknowledgment information that is for the first data packet and that is fed back by the second terminal, if the first terminal determines that the second terminal fails to decode the first data packet, the first terminal may determine a sidelink resource used to retransmit the first data packet, so that the first data packet can be retransmitted on the re-determined sidelink resource. In this way, reliability of sidelink transmission is improved. The solution may be applied to fields including unmanned driving, automated driving, driver assistance, intelligent driving, connected driving, intelligent network driving, car sharing, and artificial intelligence.
