Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure discloses a method of a user equipment (US) for transmitting uplink control information (UCI) in a wireless communication system. The method performed by the user equipment includes: determining a hybrid automatic retransmission request (HARQ) timing or HARQ timings of a dynamically scheduled physical downlink shared channel (PDSCH) and/or a semi-persistent scheduling (SPS) PDSCH and/or a physical downlink control channel (PDCCH) that indicates SPS releasing according to information sent from a base station; and transmitting generated hybrid automatic retransmission request acknowledgement (HARQ-ACK) information according to the HARQ timing or the HARQ timings determined. By applying present disclosure, it is possible to simplify the HARQ-ACK timing determination mode and can perform HARQ-ACK information transmission in time.

The present invention relates to a method of transmitting configuration information, a method of detecting control channel resources, and devices therefor. The transmission method comprises: configuring, for each coreset, control channel resources on a time unit of a scheduling unit (SU); transmitting configuration for the resources of control channel on the time unit of the SU, wherein control channel resources belong to the coreset containing a plurality of continuous or discontinuous frequency-domain physical resource blocks available to transmit a downlink control channel. The detection method comprises: receiving configuration for the resources of control channel on a time unit of an SU; performing blind detection of a downlink control channel for a user on the time unit of the SU according to the configuration information. The present invention can flexibly configure control channel resources and reduce blind detection of a control channel by a terminal, thereby attaining reduction of power consumption caused by blind detection of the control channel by the terminal and load equalization.
