1. A method, performed by a first terminal or a chip applied to the first terminal, the method comprising:
receiving access stratum configuration information of a sidelink carried by a radio resource control (RRC) message from a second terminal, wherein the access stratum configuration information indicates a maximum allowed delay of first sidelink channel state information (CSI) reporting;
triggering the first sidelink CSI reporting;
in response to the first sidelink CSI reporting being triggered, starting a first timer, wherein a length of the first timer is the maximum allowed delay of the first sidelink CSI reporting; and
canceling the first sidelink CSI reporting when the first timer times out, wherein the first sidelink CSI reporting is used by the first terminal to feed back, to the second terminal, CSI of the sidelink between the first terminal and the second terminal.
