Classification: CPC H | IPC H

Claim 10:
11. A base station (BS) configured to transmit a downlink signal in a wireless communication system supporting an unlicensed band, the BS comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connected to the at least one processor and configured to, when executed, cause the at least one processor to perform operations comprising:
transmitting, on a cell of shared spectrum, a synchronization signal/physical broadcast channel (SS/PBCH) block including quasi-co-located (QCL) information regarding a QCL relationship between SS/PBCH blocks; and
transmitting position information regarding positions of the SS/PBCH blocks within a predetermined time window,
wherein the position information includes a first 8-bit bitmap related to a plurality of groups, each group including a plurality of SS/PBCH block indexes, and a second 8-bit bitmap related to the SS/PBCH block indexes in each group,
wherein the SS/PBCH block on the cell of shared spectrum is transmitted on a position indicated based on the first 8-bit bitmap and the second 8-bit bitmap, and
wherein, based on a value of the QCL information being 32, m-th bit in the first 8-bit bitmap is set to zero for m being greater than 4.
