    Abstract: A device may wirelessly communicate with a number of different cells used in a carrier aggregation. The device may monitor physical downlink control channels (PDCCHs) on the different cells, dynamically switching between a dormant monitoring state (DS) and an active monitoring state (AS). In the DS, the UE may not monitor any PDCCH candidates on the active secondary SCells corresponding to the DS, or it may monitor PDCCH candidates in the search space (SS) set with the largest monitoring periodicity among the multiple SS sets on the active bandwidth part (BWP). In the AS, the UE may monitor a set of PDCCH candidates in physical resources configured by higher layers on the BWPs. Switching from one monitoring state to another may be facilitated through the use of a new downlink control information (DCI) format without data scheduling, a modified existing DCI format with data scheduling, and/or use of a DS timer.

    Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for a UE to request a beam quality measurement procedure. A user equipment device may be configured to perform a method including performing transmitting a request to perform a beam quality measurement procedure for downlink receptions (e.g., a P3 procedure) to a base station/network entity, receiving instructions to perform the beam quality measurement procedure from the base station, and transmitting results of the beam quality measurement procedure to the base station. In some embodiments, transmission of the request may be response to at least one trigger condition and/or detection of a condition at the UE. The request may include an indication of a preferred timing offset. The instructions to perform the beam quality measurement procedure may include a schedule for the beam quality measurement.
