Processing circuitry is configured to: determine at least one first positional relationship between the transmitting electronic device and at least one other transmitting electronic device located within a predetermined range of the transmitting electronic device, and a second positional relationship between the transmitting electronic device and the receiving electronic device; receive information regarding a candidate resource set corresponding to the receiving electronic device as assistance information, wherein the candidate resource set is a set consisting of time-frequency resource blocks that can be used by the receiving electronic device to receive data; and on the basis of the at least one first positional relationship, the second positional relationship, and the assistance information, select at least one time-frequency resource block for transmitting data from a resource pool so as to form a final available resource set.
