Abstract: Disclosed is a scheduling method for a communication network supporting an unlicensed band. An operation method of a user equipment (UE) may comprise obtaining a control channel from a partial subframe having a length of less than 1 millisecond in an unlicensed band; obtaining scheduling information from the control channel; and obtaining a data channel indicated by the scheduling information from the partial subframe. Therefore, performance of the communication network can be enhanced.

Abstract: Disclosed are operation methods of a communication node in a network supporting licensed and unlicensed bands. An operation method of a user equipment (UE) may comprises receiving, from a base station, a physical downlink control channel (PDCCH) including downlink control information (DCI) in a subframe n−1 of an unlicensed band; decoding the DCI using a common radio network temporary identifier (RNTI); and identifying the number of symbols of the subframe n−1 or a subframe n based on the decoded DCI. Therefore, a performance of the network can be enhanced.
