Wireless communication method and communication apparatus

An apparatus, comprising:

• at least one processor coupled to one or more memories configured to store non-transitory instructions, the non-transitory instructions being configured to be executed by the at least one processor to thereby perform operations comprising:
• sending first information to a network device on a first carrier, wherein the first information is usable for determining channel information on the first carrier, and the channel information on the first carrier comprises at least one of a modulation and coding scheme (MCS) on the first carrier or a spectrum efficiency on the first carrier;
• and
• receiving second information from the network device, wherein the second information is usable 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 comprises at least one of an MCS on the second carrier or a spectrum efficiency on the second carrier, and the channel information on the second carrier is determined based on the channel information on the first carrier.
