1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS), downlink control information (DCI) for scheduling of uplink data, wherein the DCI includes interlace allocation information and resource block (RB) set allocation information;
performing a carrier sensing on a plurality of RB sets, wherein the plurality of RB sets is identified based on the RB set allocation information included in the DCI; and
transmitting, to the BS, the uplink data on at least one RB of the plurality of RB sets, based on the interlace allocation information and a result of the carrier sensing on the plurality of RBs,
wherein the RB set allocation information indicates the plurality of RB sets is consecutive RB sets corresponding to a frequency bandwidth for the carrier sensing, and
wherein the interlace allocation information includes a bitmap indicating whether frequency domain resource allocation units is allocated to the UE, and a size of the bitmap is a number of the frequency domain resource allocation units.
