1. A user equipment, UE, of one or more UEs for a wireless communication network comprising one or more base stations:
wherein the UE is configured to perform a grant-free, GF, transmission to a base station of the one or more base stations using a GF transmission resource, the GF transmission being performed in accordance with a GF transmission configuration including the GF transmission resource,
wherein the UE is configured to receive from the base station a signaling, the signaling holding an indication that a transmission recognized at the base station on the GF transmission resource cannot be associated with a certain UE of the one or more UEs whereby an identity of the certain UE cannot be derived from the transmission, and
wherein, responsive to the signaling from the base station, the UE is configured to retransmit the GF transmission in accordance with a GF retransmission configuration, the GF retransmission configuration being different from the GF transmission configuration.
