  • Patent number: 12245058
    Abstract: The disclosure provides a method and a device in a first node for wireless communication. The first node first monitors a first signaling and a second signaling in a first time-frequency resource set, then judges whether to transmit a first radio signal according to a monitoring result of the first signaling, and finally transmits the first radio signal in a second time-frequency resource set, when judging to transmit the first radio signal; wherein the second signaling is not detected in the first time-frequency resource set, a signaling format corresponding to the second signaling is used for scheduling of a data signal. Through designing the first signaling and the second signaling, the disclosure solves the problem of missing detection of a sidelink scheduling signaling in Vehicle-to-Everything (V2X) caused when a data receiver only feeds back incorrect reception, thereby improving the overall performance of the system.
