FIELD: wireless communication.
SUBSTANCE: invention relates to the field of wireless communication. The technical result is achieved by the fact that the network device determines in advance whether the UE should transmit a response message corresponding to the target data, adds the determination result to the indicator signals and transmits the indicator signals to the UE so that the UE can decide whether to transmit or not transmit a response message corresponding to the target data based on the data of the network device. Therefore, the UE is prevented from continuing to transmit the response message corresponding to the target data when there is no need to transmit the response message corresponding to the target data.
EFFECT: reducing UE power consumption and resource consumption of an uplink control channel in a 5G NR system, and preventing a collision of an uplink control channel with another channel in a 5G NR system.
