Data transmission method and apparatus, and storage medium, terminal device and network device

A data transmission method, comprising:

• transmitting first configuration information, wherein the first configuration information is used to configure candidate frequency domain resources;
• and
• transmitting data on a first frequency domain resource based on the first configuration information and first sub-band information;
• wherein the first sub-band information indicates one or more sub-bands;
• based on that the first frequency domain resource is an uplink frequency domain resource, the first sub-band information is available sub-band information, and the candidate frequency domain resources comprise all available uplink frequency domain resources;
• and
• based on that the first frequency domain resource is a downlink frequency domain resource, the first sub-band information is unavailable sub-band information or available sub-band information, and the candidate frequency domain resources comprise-all available downlink frequency domain resources.

A terminal device, comprising a memory and a processor, wherein the memory stores one or more programs, the one or more programs comprising computer instructions, which, when executed by the processor, cause the processor to:

• receive first configuration information, wherein the first configuration information is used to configure candidate frequency domain resources;
• and
• transmit data on a first frequency domain resource based on the first configuration information and first sub-band information;
• wherein the first sub-band information indicates one or more sub-bands;
• based on that the first frequency domain resource is an uplink frequency domain resource, the first sub-band information is available sub-band information, and the candidate frequency domain resources comprise available uplink frequency domain resources;
• and
• based on that the first frequency domain resource is a downlink frequency domain resource, the first sub-band information is unavailable sub-band information or available sub-band information, and the candidate frequency domain resources comprise available downlink frequency domain resources.
