Sub-band resource determining method and apparatus, and device

A method for determining subband resources, applied to a base station, the method comprising:

• sending a subband resource indication message to a user equipment, wherein the subband resource indication message comprises frequency domain resource information of a first-type subband;
• wherein the subband resource indication message is used to indicate the user equipment to determine a starting position and/or an ending position of the first-type subband according to the frequency domain resource of the first-type subband indicated in the frequency domain resource information of the first-type subband, and to determine a starting position or an ending position of a guard subband based on the starting position and/or the ending position of the first-type subband;
• sending a configuration message of a guard subband to the user equipment, wherein the configuration message of the guard subband comprises a length of the guard subband;
• wherein the configuration message is used to indicate the user equipment to determine a guard subband resource from a Bandwidth Part (BWP) using the starting position of the guard subband and the length of the guard subband, or to determine the guard subband resource from the BWP based on the ending position of the guard subband and the length of the guard subband.

A user equipment comprising a processor and a non-transitory machine-readable storage medium, wherein the non-transitory machine-readable storage medium stores machine executable instructions that are able to be executed by the processor;

• and the processor is configured to execute the machine executable instructions to implement operations comprising:
• receiving a subband resource indication message from a base station, the subband resource indication message comprising frequency domain resource information of a first-type subband;
• determining a starting position and/or an ending position of the first-type subband based on the frequency domain resource of the first-type subband indicated in the frequency domain resource information of the first-type subband, and determining a starting position or an ending position of a guard subband based on the starting position and/or the ending position of the first-type subband;
• receiving a configuration message of the guard subband from the base station, the configuration message of the guard subband comprising a length of the guard subband;
• determining a guard subband resource from a Bandwidth Part (BWP) using the starting position of the guard subband and the length of the guard subband, or determining the guard subband resource from the BWP based on the ending position of the guard subband and the length of the guard subband.
