User equipment, comprising: a processing module, configured to determine a sequence to be used to send at least two acknowledgement information, ACKs/NACKs, in one uplink subframe by the user equipment, wherein the sequence is determined according to a communication standard followed by both the user equipment and a network device, or by transferring signaling before the user equipment and the network device transmit data, the at least two ACKs/NACKs comprise at least one first ACK/NACK and at least one second ACK/NACK, the first ACK/NACK and the second ACK/NACK being distinguished, and the sequence to be used to send the at least two ACKs/NACKS is sorted such that the at least one first ACK/NACK being first, and the at least one second ACK/NACK being second in the determined sequence, or the at least one second ACK/NACK being first, and the at least one first ACK/NACK being second in the determined sequence, wherein the first ACK/NACK is used to feed back a receiving status of a first signal, and the first signal is transmitted on a first frequency band; the second ACK/NACK is used to feed back a receiving status of a second signal, and the second signal is transmitted on a second frequency band; the first frequency band is a frequency band used for device-to-device, D2D, transmission and/or a frequency band used for both uplink transmission and downlink transmission; and the second frequency band is a frequency band used for downlink transmission; and a sending module, configured to send the at least two ACKs/NACKs sorted by the processing module according to the determined sequence to the network device. a processing module, configured to determine a sequence to be used to send at least two acknowledgement information, ACKs/NACKs, in one uplink subframe by the user equipment, wherein the sequence is determined according to a communication standard followed by both the user equipment and a network device, or by transferring signaling before the user equipment and the network device transmit data, the at least two ACKs/NACKs comprise at least one first ACK/NACK and at least one second ACK/NACK, the first ACK/NACK and the second ACK/NACK being distinguished, and the sequence to be used to send the at least two ACKs/NACKS is sorted such that the at least one first ACK/NACK being first, and the at least one second ACK/NACK being second in the determined sequence, or the at least one second ACK/NACK being first, and the at least one first ACK/NACK being second in the determined sequence, wherein the first ACK/NACK is used to feed back a receiving status of a first signal, and the first signal is transmitted on a first frequency band; the second ACK/NACK is used to feed back a receiving status of a second signal, and the second signal is transmitted on a second frequency band; the first frequency band is a frequency band used for device-to-device, D2D, transmission and/or a frequency band used for both uplink transmission and downlink transmission; and the second frequency band is a frequency band used for downlink transmission; and a sending module, configured to send the at least two ACKs/NACKs sorted by the processing module according to the determined sequence to the network device.
