The disclosure provides a method and a device in a node for wireless communication. A first node transmits a target radio signal, and transmits a first signaling and a first radio signal; the target radio signal includes Q index group(s), the Q index group(s) comprises(comprise) Q first-type index(es) respectively, and each of the Q index group(s) includes at least one second-type index associated with a corresponding first-type index; the first signaling schedules the first radio signal, the first signaling includes one second-type index, a first-type index included in a first index group is used for generating the first radio signal, and the first index group is one of the Q index group(s) that includes a same second-type index as the first signaling. By designing the Q index group(s) and the first index group.
