Abstract
A configuration information indication method and apparatus, applicable to systems such as a vehicle to everything V2X communication system and a vehicle-to-vehicle V2V communication system, to resolve a problem that SL transmission causes interference to DL transmission due to relatively poor indication accuracy of UL transmission time in the conventional technology. The method includes: receiving an uplink-downlink time division duplex TDD configuration from a network device; determining, based on first periodicity information included in the uplink-downlink TDD configuration, a first subcarrier spacing SCS corresponding to the first periodicity information, where the first SCS is used to indicate a sidelink SL reference SCS; and sending indication information to a second terminal device based on the uplink-downlink TDD configuration and the first SCS, where the indication information is used to indicate uplink UL transmission time corresponding to the first periodicity information.
