Abstract

A device, method, and storage medium for beam management. The method includes receiving configuration information for enabling the device to measure a first set of downlink reference signals (DL RSs) and / or a second set of DL RSs; receiving information for enabling the device to determine a quasi co-location (QCL) assumption for a channel occupancy time (COT), wherein the QCL assumption for the COT indicates availability of at least one DL beam associated with at least one DL RS of the second set of DL RSs, and / or one or more DL beams associated with one or more DL RSs of the first set of DL RSs and QCLed with at least one DL RS of the second set of DL RSs for transmissions within the COT; and determining the QCL assumption for the COT based at least in part on the received information and the configuration information.
