Claims12
A method for determining a frequency domain resource, comprising:
- determining, by a first type of sidelink device, a target device type of a receiving device for sidelink communication:
- determining, by the first type of sidelink device, a target frequency domain resource for sidelink communication with the receiving device according to the target device type, wherein the target frequency domain resource for the sidelink communication with the receiving device is a subset of sidelink communication frequency domain resources used by the first type of sidelink device;
- wherein the method further comprises:
- determining, based on a determination that the target device type comprises a second type of sidelink device, a target frequency domain resource for sidelink communication with the second type of sidelink device,
- wherein the second type of sidelink device is the first type of sidelink device in an energy-saving state, or the second type of sidelink device is a sidelink device having a different device type from the first type of sidelink device and having high energy consumption requirements;
- wherein the method further comprises:
- determining a first frequency domain resource range adopted by the first type of sidelink device for the sidelink communication with the second type of sidelink device;
- and
- determining the target frequency domain resource within the first frequency domain resource range;
- wherein the method further comprises:
- taking a frequency domain resource overlapping with a frequency domain resource of a bandwidth part (BWP) adopted by the second type of sidelink device as the first frequency domain resource range.
