Feedback information processing method, device and system, base station and terminal

(canceled)

A feedback information receiving method, comprising:

• sending transmission blocks from a plurality of second nodes to a first node;
• and
• receiving a media access control protocol data unit (MAC PDU) sent from the first mode, wherein the MAC PDU is obtained through multiplexing feedback information for the plurality of second nodes in one MAC PDU by the first node, the feedback information is information generated after the first node correctly receives the transmission blocks, and the feedback information comprises a plurality of pieces of bit information.

A base station, comprising:

• a processor and a memory storing processor-executable instructions, wherein when the instructions are executed by the processor, the processor executes a following operation:
• multiplexing feedback information for a plurality of terminals in a media access control protocol data unit (MAC PDU), wherein the feedback information is information generated after the base station correctly receives transmission blocks from the plurality of terminals, and the feedback comprises a plurality of pieces of bit information.

A terminal, comprising:

• a processor and a memory storing processor-executable instructions, wherein when the instructions are executed by the processor, the processor executes a following operation:
• multiplexing feedback information for a plurality of base stations in a media access control protocol data unit (MAC PDU), wherein the feedback information is information generated after the terminal correctly receives transmission blocks from the plurality of base stations, and the feedback comprises a plurality of pieces of bit information.
