determining whether the guard band is activated based on the configuration information; and when the guard band is activated, determining whether to transmit an uplink channel according to an uplink-downlink configuration in a time domain and a frequency domain. ## Claims ### Claim 1 An operating method of a user equipment (UE) in a wireless communication system, the operating method comprising: receiving configuration information for a guard band; determining whether the guard band is activated based on the configuration information; and when the guard band is activated, determining whether to transmit an uplink channel according to an uplink-downlink configuration in a time domain and a frequency domain. ### Claim 2 (depends on 1) The operating method of claim 1, wherein the method further comprises, when the guard band is not activated, determining whether to transmit the uplink channel according to an uplink-downlink configuration of a time division duplex (TDD) system. ### Claim 3 (depends on 1) The operating method of claim 1, wherein the method further comprises: receiving scheduling information for the uplink channel through higher-layer signaling; determining whether a transmission resource for the uplink channel overlaps at least a part of a resource configured for a downlink or the guard band based on the scheduling information; and when the transmission resource overlaps at least a part of the resource configured for the downlink or the guard band, determining not to transmit the uplink channel. ### Claim 4 (depends on 3) The operating method of claim 3, wherein the method further comprises, when the transmission resource does not overlap the resource configured for the downlink or the guard band at all, transmitting the uplink channel based on an uplink-downlink configuration in the time domain and the frequency domain. ### Claim 5 (depends on 1) The operating method of claim 1, wherein the uplink-downlink configuration in the time domain and the frequency domain is performed through cell-specific information, higher-layer signaling, or a downlink control channel (DCI). ### Claim 6 A user equipment (UE) in a wireless communication system, the UE comprising: a transceiver; and at least one processor, wherein the at least one processor is configured to: receive configuration information for a guard band; determine whether the guard band is activated based on the configuration information; and when the guard band is activated, determine whether to transmit an uplink channel according to an uplink-downlink configuration in a time domain and a frequency domain. ### Claim 7 (depends on 6) The UE of claim 6, wherein the at least one processor is further configured to, when the guard band is not activated, determine whether to transmit the uplink channel according to an uplink-downlink configuration of a time division duplex (TDD) system. ### Claim 8 (depends on 6) The UE of claim 6, wherein the at least one processor is further configured to: receive scheduling information for the uplink channel through higher-layer signaling; determining whether a transmission resource for the uplink channel overlaps at least a part of a resource configured for a downlink or the guard band based on the scheduling information; and when the transmission resource overlaps at least a part of the resource configured for the downlink or the guard band, determine not to transmit the uplink channel. ### Claim 9 (depends on 8) The UE of claim 8, wherein the at least one processor is further configured to, when the transmission resource does not overlap the resource configured for the downlink or the guard band at all, transmit the uplink channel based on an uplink-downlink configuration in the time domain and the frequency domain. ### Claim 10 (depends on 6) The UE of claim 6, wherein the uplink-downlink configuration in the time domain and the frequency domain is performed through cell-specific information, higher-layer signaling, or a downlink control channel (DCI). ### Claim 11 An operating method of a base station (BS) in a wireless communication system, the operating method comprising: transmitting configuration information for a guard band to a user equipment (UE); and when the guard band is activated, receiving an uplink channel according to an uplink-downlink configuration in a time domain and a frequency domain, wherein whether the guard band is activated is determined by the UE based on the configuration information. ### Claim 12 (depends on 11) The operating method of claim 11, wherein, when the guard band is not activated, whether the uplink channel is transmitted is determined according to an uplink-downlink configuration of a time division duplex (TDD) system. ### Claim 13 (depends on 11) The operating method of claim 11, further comprising transmitting scheduling information for the uplink channel to the UE through higher-layer signaling, wherein the uplink channel is not received, when a transmission resource for the uplink channel overlaps at least a part of a resource configured for a downlink or the guard band. ### Claim 14 (depends on 13) The operating method of claim 13, wherein the uplink channel is received based on an uplink-downlink configuration in the time domain and the frequency domain, when the transmission resource does not overlap the resource configured for the downlink or the guard band at all. ### Claim 15 A base station (BS) in a wireless communication system, the BS comprising: a transceiver; and at least one processor, wherein the at least one processor is configured to: transmit configuration for a guard band to a user equipment (UE); when the guard band is activated, receive an uplink channel according to an uplink-downlink configuration in a time domain and a frequency domain; and whether the guard band is activated is determined by the UE based on the configuration information.
