Method for using radio interface technology, apparatus, and communications system

A method for transmitting and receiving a service, comprising:

• sending, by a base station to a terminal device, radio resource configuration information, wherein the radio resource configuration information comprises frequency band information of N frequency ranges and characteristic information of radio interface technologies corresponding to each of the N frequency ranges, wherein N≥2;
• sending, by the base station to the terminal device, indication information indicating a frequency range in which a physical layer resource is to be used by the terminal device to transmit and receive the service;
• and
• transceiving, between the base station and the terminal device, the service using a radio interface technology corresponding to the frequency range;
• wherein characteristics of the radio interface technologies comprise at least one of:
• a cyclic prefix (CP) length, a duration of an orthogonal frequency division multiplexing (OFDM) symbol, or a subcarrier spacing.

A terminal device, comprising:

• a transceiver, a processor, and a non-transitory computer-readable storage medium storing programming instructions for execution by the processor;
• wherein the programming instructions, when executed, cause the terminal device to:
• receive radio resource configuration information from a base station, wherein the radio resource configuration information comprises frequency band information of N frequency ranges and characteristic information of radio interface technologies corresponding to each of the N frequency ranges, wherein N≥2;
• receive indication information from the base station, wherein the indication information indicates a frequency range in which a physical layer resource is to be used by the terminal device to transmit and receive a service;
• and
• transceiving, between the terminal device and the base station, the service using a radio interface technology corresponding to the frequency range;
