Method for indicating frequency domain resource, terminal device and network device

A terminal device, comprising:

• a transceiver, a memory, a processor, and a computer program stored on the memory and operable on the processor,
• wherein the processor, when running the computer program, is configured to:
• control the transceiver to receive first indication information sent by a network device, wherein the first indication information indicates, by using a first unit, whether a resource region in a system frequency domain resource comprises a target frequency domain resource allocated by the network device from the system frequency domain resource to the terminal device, wherein,
• the system frequency domain resource comprises multiple types of frequency domain resources, the multiple types of frequency domain resources have different sub-carrier internals, the multiple types of frequency domain resources are respectively composed of minimum frequency domain scheduling units of different sizes, a size of the resource region is the same as a size of the first unit, the size of the first unit is M times a size of a minimum frequency domain scheduling unit of a frequency domain resource having a second sub-carrier interval, M is an integer greater than or equal to 1, and the second sub-carrier interval is greater than a sub-carrier interval of the target frequency domain resource;
• and
• determine, according to the first indication information, a resource region where the target frequency domain resource is located.

A terminal device, comprising:

• a receiving module, configured to receive resource location indication information sent by a network device;
• the receiving module is further configured to receive resource type indication information sent by the terminal device;
• and
• a determining module, configured to determine, according to the resource location indication information, a location of a target frequency domain resource in a system frequency domain resource, wherein the target frequency domain resource is a frequency domain resource allocated by the network device from multiple types of frequency domain resources to the terminal device, and different types of frequency domain resources have different sub-carrier intervals;
• the determining module is further configured to determine, according to the resource type indication information, a type of a frequency domain resource comprised in the target frequency domain resource.
