1. A method performed by a user equipment (UE) comprising:
transmitting a transport block (TB) to a base station in a grant-free uplink transmission, the TB associated with a hybrid automatic repeat request (HARQ) process identifier (ID);
receiving a HARQ feedback message having a payload that includes multiple positions, wherein there is a mapping between each one of the multiple positions and a respective different HARQ process ID for the UE, wherein each one of the multiple positions includes an indication of an acknowledgement (ACK) or a negative acknowledgement (NACK) corresponding to the respective different HARQ process ID for the UE, and the HARQ feedback message includes an indication of an ACK or a NACK for the TB, and wherein an earliest time of the indication of the ACK or the NACK for the TB to be received by the UE is after a time period since an initial grant-free transmission of the TB or a last repetition of repetitions of the TB finishes, the time period being configured via radio resource control (RRC) signaling.
