Method and device in nodes used for wireless communication

A second node for wireless communications, comprising:

• a second transmitter, transmitting a first signaling;
• and transmitting a first signal in a first time window;
• and
• a second receiver, receiving a first bit block in a first radio resource block;
• wherein the first signaling is used for indicating configuration information for the first signal;
• the first time window is one of M time windows, and any two time windows of the M time windows are orthogonal, M being a positive integer greater than 1;
• the first radio resource block belongs to a target time window in time domain, and any of the M time windows is associated with the target time window;
• the first bit block comprises a first bit sub-block, the first bit sub-block being used to indicate whether the first signal is correctly received;
• a position of the first time window in the M time windows is used to determine a size of the first bit block;
• the first bit block comprises a positive integer number of bit(s), and the first bit sub-block comprises a positive integer number of bit(s).
