1. A method for a user equipment (UE) for performing a hybrid automatic repeat request (HARQ) feedback operation for a semi-persistent scheduling (SPS) transmission, the method comprising:
receiving, from a network, a transmission configuration for a scheduled transmission, the transmission configuration indicating a first number of HARQ processes used for the scheduled transmission;
receiving, from the network, an SPS transmission configuration for an SPS transmission, the SPS transmission configuration indicating a second number of HARQ processes used for the SPS transmission;
receiving, from the network, scheduling signaling including a reserved HARQ process number for indicating that a HARQ state feedback operation for the scheduled transmission is disabled;
determining a first HARQ process number corresponding to the SPS transmission, the first HARQ process number being selected according to the second number of HARQ processes, the first HARQ process number being equivalent to the reserved HARQ process number; and
transmitting, to the network, a HARQ state feedback for the SPS transmission with a second HARQ process number derived according to the first HARQ process number.
