Method for sending and receiving assistance resource set, and storage medium

A method for receiving an assistance resource set, performed by a second device, comprising:

• receiving first stage sidelink control information from a first device;
• and
• receiving second stage sidelink control information from the first device, wherein the second stage sidelink control information comprises an information field for indicating an assistance resource set, and the second stage sidelink control information is configured to assist the second device in resource selection;
• wherein the second stage sidelink control information comprises:
• a first information field for indicating a time domain resource of the assistance resource set, wherein a first bit size corresponding to the first information field is determined based on a number of slots of the time domain resource of the assistance resource set and an indication granularity of the first information field;
• and
• a second information field for indicating a frequency domain resource of the assistance resource set, wherein a second bit size corresponding to the second information field is determined based on a number of subchannels where the frequency domain resource of the assistance resource set is located and an indication granularity of the second information field.

A device for sending an assistance resource set, comprising:

• a processor;
• a memory for storing instructions executable by the processor;
• wherein
• the processor is configured to implement a method for sending an assistance resource set, the method comprising:
• sending first stage sidelink control information to a second device;
• determining second stage sidelink control information, wherein the second stage sidelink control information comprises an information field for indicating an assistance resource set;
• and
• sending the second stage sidelink control information to the second device, wherein the second stage sidelink control information is configured to assist the second device in resource selection;
• wherein the second stage sidelink control information comprises:
• a first information field for indicating a time domain resource of the assistance resource set, wherein a first bit size corresponding to the first information field is determined based on a number of slots of the time domain resource of the assistance resource set and an indication granularity of the first information field;
• and
• a second information field for indicating a frequency domain resource of the assistance resource set, wherein a second bit size corresponding to the second information field is determined based on a number of subchannels where the frequency domain resource of the assistance resource set is located and an indication granularity of the second information field.
