A method performed by a user equipment, the method comprising: receiving first information related to a plurality of reference signal resource sets for a plurality of bandwidth parts, wherein each reference signal resource set of the plurality of reference signal resource sets corresponds to a respective bandwidth part of the plurality of bandwidth parts, and each bandwidth part of the plurality of bandwidth parts: comprises a group of contiguous physical resource blocks; is less than a size of an entire bandwidth corresponding to the user equipment; and is greater than or equal to a bandwidth of a synchronization signal/physical broadcast channel block; receiving a plurality of spatial quasi-co-location information corresponding to a plurality of reference signal resources of the plurality of reference signal resource sets; assessing a radio link quality based on the plurality of spatial quasi-co-location information; receiving a command for active bandwidth part switching, and switching an active bandwidth part from a first bandwidth part to a second bandwidth part; and if a first reference signal resource of a first reference signal resource set for the first bandwidth part is indicated to be spatially quasi-co-located with a second reference signal resource of a second reference signal resource set for the second bandwidth part, then evaluating the radio link quality on the second reference signal resource over a previous time period taking into account measurements made for the first reference signal resource. receiving first information related to a plurality of reference signal resource sets for a plurality of bandwidth parts, wherein each reference signal resource set of the plurality of reference signal resource sets corresponds to a respective bandwidth part of the plurality of bandwidth parts, and each bandwidth part of the plurality of bandwidth parts: comprises a group of contiguous physical resource blocks; is less than a size of an entire bandwidth corresponding to the user equipment; and is greater than or equal to a bandwidth of a synchronization signal/physical broadcast channel block; comprises a group of contiguous physical resource blocks; is less than a size of an entire bandwidth corresponding to the user equipment; and is greater than or equal to a bandwidth of a synchronization signal/physical broadcast channel block; receiving a plurality of spatial quasi-co-location information corresponding to a plurality of reference signal resources of the plurality of reference signal resource sets; assessing a radio link quality based on the plurality of spatial quasi-co-location information; receiving a command for active bandwidth part switching, and switching an active bandwidth part from a first bandwidth part to a second bandwidth part; and if a first reference signal resource of a first reference signal resource set for the first bandwidth part is indicated to be spatially quasi-co-located with a second reference signal resource of a second reference signal resource set for the second bandwidth part, then evaluating the radio link quality on the second reference signal resource over a previous time period taking into account measurements made for the first reference signal resource. <EOS>
