    Abstract: Systems and methods for cross layer optimization for selection of a best or most preferred cell from conditional special cell (SpCell) change candidate cells are disclosed. The conditional SpCell change may be, for example, a conditional handover (CHO) or a conditional primary cell of a secondary cell group (PSCell) change (CPC). Conditions for a conditional SpCell change may be provided to a user equipment (UE). It may be that measurements on multiple cells meet the condition(s) for a conditional SpCell change by the UE. Preferences/criteria for selecting a cell from these multiple compliant candidate cells meeting the conditional SpCell change conditions are discussed herein. These criteria may include, but are not limited to, for example, a cell quality, an inter-versus intra-frequency handover, bandwidth, component carrier (CC) use, band, carrier type, needs/criticality of the application, congestion, frequency range, multiple subscriber identity module (MSIM) considerations, etc.

    Abstract: A wireless network may include a PCELL base station, an SCELL base station, and user equipment (UE) that communicate using standalone carrier aggregation. The UE may receive PCELL signals during first measurement periods, may perform first measurements on the PCELL signals, may receive SCELL signals during second measurement periods, and may perform second measurements on the SCELL signals. When a scheduled reporting time approaches, the UE may compare a duration between a most recent of the second measurement periods and the reporting time to a threshold. If the duration is less than the threshold, the UE may include the most recent second measurement in a measurement report transmitted at the scheduled reporting time. When the duration exceeds the threshold, the receiver may perform a third measurement on the SCELL signals during an unscheduled period prior to the reporting time and may include the third measurement in the measurement report.
