Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify a set of time instances to monitor for paging, wherein the set of time instances are identified based at least in part on a first discontinuous reception (DRX) cycle parameter set, identify a subset of time instances, of the set of time instances, for which a narrowband reference signal is to be monitored irrespective of whether paging is present on the subset of time instances, wherein the subset of time instances is identified based at least on a second DRX cycle parameter set; and communicate based at least on the set of time instances and the subset of time instances. Numerous other aspects are provided.
