Various arrangements for performing uplink grant-free transmissions are presented herein. An instance of user equipment (UE) may determine data that is to be transmitted using a grant-free (GF) uplink transmission to a base station of a cellular network. The UE may select a first GF resource block and a second GF resource block. The UE may transmit a GF transmission that comprises a data payload and a first pointer at the first GF resource block. The first pointer may refer to the second GF resource block.
