Communications method and apparatus

A communications method applied to a communication apparatus, the method comprising:

• determining whether a first capability of a terminal device is less than or equal to a second capability of the terminal device, wherein the first capability is a capability of the terminal device working at a first frequency based on the terminal device supporting only a first radio access technology, the second capability is a capability of the terminal device corresponding to the first frequency in a first frequency combination, the first frequency combination comprises the first frequency and a second frequency, the first frequency corresponds to the first radio access technology, and the second frequency corresponds to a second radio access technology;
• and
• based on the first capability being less than or equal to the second capability, sending a first message to the terminal device, wherein the first message indicates the terminal device to measure the second frequency, the first message does not comprise a configuration of a first measurement gap, and the first measurement gap is used to measure the second frequency.

A communications method applied to a communication apparatus, the method comprising:

• determining one or more frequency combinations, wherein a capability of a terminal device corresponding to a fifth frequency in each of the one or more frequency combinations is greater than a capability of the terminal device working at the fifth frequency, based on the terminal device supporting only a first radio access technology, or the capability of the terminal device corresponding to the fifth frequency in each of the one or more frequency combinations is less than or equal to the capability of the terminal device working at the fifth frequency based on the terminal device supporting only the first radio access technology, each frequency combination comprises the fifth frequency and a sixth frequency, the fifth frequency corresponds to the first radio access technology, and the sixth frequency corresponds to a second radio access technology;
• and
• sending indication information to a network device, wherein the indication information indicates the one or more frequency combinations.

A communications apparatus, comprising a processor and a transceiver, wherein the processor and the transceiver are coupled to each other, and cooperate with each other to perform a method including:

• determining whether a first capability of a terminal device is less than or equal to a second capability of the terminal device, wherein the first capability is a capability of the terminal device working at a first frequency based on the terminal device supporting only a first radio access technology, the second capability is a capability of the terminal device corresponding to the first frequency in a first frequency combination, the first frequency combination comprises the first frequency and a second frequency, the first frequency corresponds to the first radio access technology, and the second frequency corresponds to a second radio access technology;
• and
• based on the first capability being less than or equal to the second capability, sending a first message to the terminal device, wherein the first message indicates the terminal device to measure the second frequency, the first message does not comprise a configuration of a first measurement gap, and the first measurement gap is used to measure the second frequency.

A non-transitory computer-readable storage medium, storing a computer program, which is run on a computer, and causes the computer to perform a method including:

• determining whether a first capability of a terminal device is less than or equal to a second capability of the terminal device, wherein the first capability is a capability of the terminal device working at a first frequency based on the terminal device supporting only a first radio access technology, the second capability is a capability of the terminal device corresponding to the first frequency in a first frequency combination, the first frequency combination comprises the first frequency and a second frequency, the first frequency corresponds to the first radio access technology, and the second frequency corresponds to a second radio access technology;
• and
• based on the first capability being less than or equal to the second capability, sending a first message to the terminal device, wherein the first message indicates the terminal device to measure the second frequency, the first message does not comprise a configuration of a first measurement gap, and the first measurement gap is used to measure the second frequency.
