the first subchannel set is a first available subchannel set sensed by a first terminal device on a sidelink (SL); and
the first SCI is free from modulation and coding scheme (MCS) information; and
receiving second SCI sent by the second terminal device, wherein:
the second SCI comprises:
information about a second subchannel set; and
the second subchannel set is a second available subchannel set sensed by the second terminal device on the SL.
