A user equipment (UE) configures at least one data subband set within a carrier, and communicating with a base station by using the at least one data subband set. Each of the at least one data subband set consists of at least one data subband, and each of the at least one data subband consists of a set of consecutive physical resource blocks (PRBs). Each of the at least one data subband set may be configured per numerology. The at least one data subband may correspond to at least one bandwidth part (BWP). ## Claims ### Claim 1 A method for configuring a data subband set by a user equipment (UE) in a wireless communication system, the method comprising: configuring at least one data subband set within a carrier; and communicating with a base station using the at least one data subband set, wherein each of the at least one data subband set comprises at least one data subband, and wherein a maximum number of the at least one data subband is 4 and only one data subband among the at least one data subband is an active data subband, wherein each of the at least one data subband comprises a set of consecutive physical resource blocks (PRBs), wherein each of the at least one data subband set is configured per numerology, wherein based on at least two data subband sets and based on overlapping data subbands belonging to different overlapped data subband sets, the UE transmits UE capability information informing the base station whether the overlapping data subbands are capable of simultaneous activation by the base station, wherein based on a request that the UE report a channel state information (CSI) measurement for each of the overlapping data subbands, the UE performs the CSI measurement for one of the overlapping data subbands and reuses a result of the CSI measurement for remaining overlapping data subbands, wherein the at least one data subband includes a control resource set (CORESET) for scheduling in the at least one data subband, wherein based on the CSI measurement being requested outside of the active data subband, the UE reports a necessary retuning gap to the base station based on the request of the CSI measurement, and performs the CSI measurement within a measurement gap and does not monitor the CORESET for the active data subband during the CSI measurement, and wherein the UE receives information on the measurement gap which is determined based on the necessary retuning gap from the base station, where the measurement gap is determined per each of the at least one data subband. ### Claim 2 (depends on 1) The method of claim 1, wherein a CORESET associated with a first data subband among the at least one data subband schedules a second data subband. ### Claim 3 (depends on 1) The method of claim 1, wherein the at least one data subband set includes multiple data subband sets. ### Claim 4 (depends on 3) The method of claim 3, wherein the multiple data subband sets are multiplexed by frequency division multiplexing (FDM). ### Claim 5 (depends on 3) The method of claim 3, wherein the multiple data subband sets are partially or fully overlapped with each other. ### Claim 6 (depends on 3) The method of claim 3, wherein the multiple data subband sets are covered by a single radio frequency (RF) of the UE. ### Claim 7 (depends on 3) The method of claim 3, wherein numerologies for the multiple data subband sets are identical. ### Claim 8 (depends on 3) The method of claim 3, wherein a CORESET associated with a first data subband in a first data subband set among the multiple data subband sets schedules a second data subband in a second data subband set among the multiple data subband sets. ### Claim 9 (depends on 1) The method of claim 1, wherein the UE is in communication with at least one of a mobile device, a network, or autonomous vehicles other than the UE. ### Claim 10 A user equipment (UE) in a wireless communication system, the UE comprising: a memory; a transceiver; and a processor, operatively coupled to the memory and the transceiver, that: configures at least one data subband set within a carrier; and communicates with a base station using the at least one data subband set, wherein each of the at least one data subband set comprises at least one data subband, and wherein a maximum number of the at least one data subband is 4 and only one data subband among the at least one data subband is an active data subband, wherein each of the at least one data subband comprises a set of consecutive physical resource blocks (PRBs), wherein each of the at least one data subband set is configured per numerology, wherein based on at least two data subband sets and based on overlapping data subbands belonging to different overlapping data subband sets, the UE transmits UE capability information informing the base station whether the overlapping data subbands are capable of simultaneous activation by the base station, wherein based on a request that the UE a report channel state information (CSI) measurement for each of the overlapping data subbands, the UE performs the CSI measurement for one of the overlapping data subbands and reuses a result of the CSI measurement for remaining overlapping data subbands, wherein the at least one data subband includes a control resource set (CORESET) for scheduling in the at least one data subband, wherein based on the CSI measurement being requested outside of the active data subband, the UE reports a necessary retuning gap to the base station based on the request of the CSI measurement, and performs the CSI measurement within a measurement gap and does not monitor the CORESET for the active data subband during the CSI measurement, and wherein the UE receives information on the measurement gap which is determined based on the necessary retuning gap from the base station, where the measurement gap is determined per each of the at least one data subband.
