Abstract
The present disclosure provides a method and device used in wireless communication nodes. A first node receives a first radio signal; and transmits a first-type signaling on a first radio resource, the first-type signaling being used for indicating that the first radio signal is correctly received; or, transmits a second-type signaling on a second radio resource, the second-type signaling being used for indicating that the first radio signal is not correctly received; herein, time-domain resources occupied by the first radio resource and time-domain resource occupied by the second radio resources are orthogonal. Under Groupcast communication mode, the present disclosure transmits a retransmission signal to a UE that not correctly receives a radio signal through a UE that correctly receives a radio signal in the group, so as to achieve the purpose of improving signal received quality and resource utilization efficiency.
