Method and device in communication node used for wireless communication

A second node for wireless communication, comprising:

• a third transmitter, to transmit a first signaling;
• and
• a third receiver, to receive a third signal in a third air interface resource block, the third air interface resource block is one PUCCH resource;
• wherein the first signaling includes DCI, or, the first signaling includes information in partial or all fields in one IE;
• the first signaling is used for determining a first air interface resource block, and the first air interface resource block is used for determining a second air interface resource block;
• a transmitter of the third signal transmits a first bit block set in the first air interface resource block and receives a second signal in the second air interface resource block;
• any bit block included in the first bit block set is one TB;
• the second signal indicates whether the first bit block set is correctly received;
• the second signal is used for determining the third signal, and the third signal indicates whether the first bit block set is correctly received;
• the second air interface resource block is later than the first air interface resource block in time domain, and the third air interface resource block is later than the second air interface resource block in time domain;
• the first signaling indicates a first time interval, a time interval between a slot to which the third air interface resource block belongs and a slot to which the second air interface resource block belongs is the first time interval;
• the second node is different from a transmitter of the second signal;
• the first signaling is transmitted on a PDCCH or a PDSCH, the first bit block set is transmitted on a PSSCH, the second signal is transmitted on a PSFCH, and the third signal is transmitted on a PUCCH.
