Abstract
An information transmission method and a communication apparatus that is applied to a communication system, for example, V2X, LTE-V, MTC, IoT, LTE-M, and M2M, to perform information transmission between terminal devices in a contention-based scheduling mode. The method includes: a first terminal device sends first sidelink control information SCI to a second terminal device, where the first SCI includes information about a first subchannel set, the first subchannel set is an available subchannel set sensed by the first terminal device on a sidelink SL, and the first SCI does not include modulation and coding scheme MCS information. The first SCI does not include the MCS information. This can both reduce signaling overheads of the first terminal device, and improve efficiency of demodulating the first SCI by the second terminal device.
