Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A base station (BS) in a wireless communication system, the BS comprising:
a transceiver; and
at least one processor configured to:
control the transceiver to transmit, to a user equipment (UE), downlink control information (DCI) for scheduling of uplink data, wherein the DCI includes interlace allocation information and resource block (RB) set allocation information; and
control the transceiver to receive, from the UE, the uplink data on RB of a plurality of RB sets,

wherein the uplink data is received from the UE, based on the interlace allocation information and a result of a carrier sensing of the UE on the plurality of RB sets,
wherein the plurality of RB sets is identified based on the RB set allocation information included in the DCI,
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.
