1. A receiving-side electronic device for a receiving side of a communication system, the receiving-side electronic device being capable of communicating with plural transmitting-side electronic devices of a transmitting side of the communication system, the receiving-side electronic device comprising a processing circuit configured to:
receive an initial transmission of data and other information from a first electronic device among the more than one transmitting-side electronic devices,
wherein the other information includes:
information indicating current resources used by the first electronic device for the initial transmission of the data, and
binary data indicating first reserved resources that are available for use for the retransmission of the data and second reserved resources that are not available for use for the retransmission of the data by the first electronic device, the first and second reserved resources being the resources assigned to other transmitting-side electronic devices of the plural transmitting-side electronic devices,
perform decoding on the data information in the initial transmission, and
based on data information in the initial transmission of the data not being successfully decoded the receiving-side electronic device:
decode the other information,
perform sensing on the first reserved resources to compare a corresponding energy level to a predetermined threshold so as to identify at least one resource of the first reserved resources that is not currently being used,
send auxiliary information as feedback to the first electronic device, the auxiliary information identifying the at least one resource of the first reserved resources that is not currently being used, and
based on the auxiliary information, receive the retransmission of the data via the at least one resource of the reserved resources that is not currently being used.
