Abstract: This application provides a method for communicating a modulation and coding scheme (MCS). A terminal device obtains a modulation order, a code rate, or a spectral efficiency, determines an index of a reference MCS from a mapping table based on the obtained modulation order, code rate, or spectral efficiency, and reports the index of the reference MCS to a network device. The mapping table includes one or more mapping relationships between an MCS index and a modulation order, a code rate, or a spectral efficiency. The terminal device may process uplink or downlink data based on the determined MCS, thereby improving data transmission reliability.

Abstract: 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.

Abstract: This application provides a sidelink configuration method and apparatus, a device, and a storage medium. In one example, before each sidelink transmission is performed, a terminal device at a transmit end sends SCI to a terminal device at a receive end. In this solution, transmission on information needed for sidelink transmissions is performed by using sidelink RRC, so that the terminal device at the receive end obtains a time-frequency resource configuration of sidelink transmissions, and further obtains a HARQ process identifier of each transmission.
