This application provides a sidelink communication method. The method includes: A first terminal device determines one or more pieces of first configuration information, where the one or more pieces of first configuration information correspond to one or more sidelinks, each piece of the first configuration information is used to configure a discontinuous reception DRX related parameter of a corresponding sidelink, and the first terminal device is a sending device or a receiving device on the one or more sidelinks. The first terminal device maintains, based on each piece of the first configuration information, a status of the discontinuous reception DRX corresponding to each piece of the first configuration information.

Sidelink communication method and communication apparatus

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.

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.
