Method and apparatus for sending response information, storage medium, and electronic device

A method for transmitting response information, wherein in a sidelink communication system, User Equipment (UE) communicate directly with each other through a sidelink, and the UE comprise a data transmitter transmitting user data and a data receiver receiving the user data;

• the method is applied to the data receiver in the sidelink communication system and comprises:
• receiving locations of time-frequency resources for transmission of response information indicated by the data transmitter;
• determining at least one selected location of time-frequency resource from the locations of the time-frequency resources for the transmission of the response information indicated by the data transmitter;
• and
• after receiving the user data from the data transmitter, transmitting the response information to the data transmitter on the at least one selected location of the time-frequency resource.

An electronic device, wherein in a sidelink communication system, User Equipment (UE) communicate directly with each other through a sidelink, and the UE comprise a data transmitter transmitting user data and a data receiver receiving the user data;

• the electronic device is applied to the data transmitter in the sidelink communication system and comprises:
• a processor;
• and
• memory for storing one or more instructions executable by the processor;
• wherein the processor is configured to determine a location of a time-frequency resource for response information transmitted by the data receiver of the user data, indicate the location of the time-frequency resource for the transmission of the response information to the data receiver, and receive the response information from the data receiver at the location of the time-frequency resource.
