Carrier aggregation capability reporting apparatus and method, and carrier measurement apparatus and method

A communication apparatus, comprising:

• a processor;
• and
• a memory storing program instructions that, when executed by the processor, cause the communication apparatus to perform operations comprising:
• sending carrier range information to a terminal, wherein the carrier range information indicates the terminal to report capability information to the communication apparatus, and wherein the carrier range information carries at least one of an aggregated carrier bandwidth upper limit of a band or a carrier quantity upper limit of the band;
• and
• receiving capability information of at least one carrier from the terminal, wherein the capability information corresponds to at least one carrier in the band, and wherein an aggregated bandwidth of the at least one carrier is less than or equal to the aggregated carrier bandwidth upper limit and/or a quantity of carriers of the least one carrier is less than or equal to the carrier quantity upper limit.
