Abstract: In wireless communication networks using carrier aggregation, a user equipment (UE) may monitor a downlink radio link quality of secondary cells for an event indicating failure of the communication link with the secondary cell. When a failure event is detected, the UE declares a failure state on the secondary cell. In response to the failure state, the UE may adjust operations related to the secondary component carrier in order to save power and resources.

Abstract: Systems and methods for Carrier Sense Adaptive Transmission (CSAT) communication scheme identification and mitigation in unlicensed spectrum are disclosed. The identification may comprise, for example, identifying CSAT communication based on a presence of a first signal and an absence of a second signal of a Radio Access Technology (RAT) during a period of time. The mitigation may comprise, for example, limiting transmission of at least a first signal by the RAT on a resource for a period of time associated with an adaptable duty cycle used for the CSAT communication, and transmitting a second signal by the RAT on the resource during the period of time.

Abstract: Certain aspects of the present disclosure provide techniques for adapting search, measurement, and loop tracking periodicities in new radio communications. A method that may be performed by a user equipment (UE) includes determining, based on one or more parameters, a first periodicity to perform a search to detect one or more component carriers (CCs), cells, beams, or a combination thereof; a second periodicity to perform measurement of one or more cells, beams, or both in one more detected CCs; and a third periodicity to perform loop tracking to monitor a downlink serving quality, an uplink serving beam quality, or both of a cell. The method may further includes performing the search at the determined first periodicity, measurement at the determined second periodicity, and loop tracking at the determined third periodicity.
