Abstract: A method includes receiving first information from a terminal device on a first carrier, and sending second information to the terminal device. The first information is useable for determining channel information on the first carrier. The channel information on the first carrier includes a modulation and coding scheme (MCS) on the first carrier or a spectrum efficiency on the first carrier. The second information is useable for scheduling a transmission resource on a second carrier. The second information is useable to indicate channel information on the second carrier. The channel information on the second carrier includes at least one of an MCS on the second carrier or a spectrum efficiency on the second carrier. The channel information on the second carrier is determined based on the channel information on the first carrier.

Abstract: Embodiments of this application provide a synchronization signal block transmission method and a communication apparatus. In an example method, a first synchronization signal block SSB from a network device is received, where the first SSB is a first-type SSB for a first terminal device. If the first SSB is a second-type SSB for a second terminal device, a first control-resource set and/or first common search space is determined based on the first SSB. In the example method, different results may be obtained when the second terminal device and the first terminal device identify a type of the first SSB, and the second terminal device and the first terminal device may use the first SSB in different manners.
