    摘要: The disclosure provides a method and a device in a node used for wireless communication. A first node monitors a first-type signaling and a second-type signaling in a first time-frequency resource pool and a second time-frequency resource pool respectively, receives a first signaling, and transmits a first information block. The first signaling is used for determining the first information block; the first signaling includes a first field; when the first signaling is the first-type signaling, a value of the first field is related to a number of the first-type signalings transmitted in the first time-frequency resource pool, and is unrelated to a number of the second-type signalings transmitted in the second time-frequency resource pool. The above method improves the efficiency of HARQ feedback in sidelink transmission.
