In wireless communication networks using carrier aggregation including a secondary component carrier in unlicensed spectrum, a user equipment (UE) may monitor a downlink radio link quality of secondary cells for an event indicating failure of a communication link in the unlicensed spectrum with a secondary cell. The UE detects one or more failure events based on the downlink radio link quality. When a designated set of failure events 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 the unlicensed spectrum in order to save power and resources.

Managing secondary cell connections in unlicensed spectrum

Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine that the wireless communication device is configured to use a primary component carrier (PCC), a first secondary component carrier (SCC), and a second SCC for carrier aggregation. A primary cell may be associated with the PCC, a first secondary cell may be associated with the first SCC, and a second secondary cell may be associated with the second SCC. The first secondary cell may provide control information for the second secondary cell. The wireless communication device may monitor at least one of the first SCC or the second SCC. The wireless communication device may perform an action associated with the second secondary cell based, at least in part, on monitoring the at least one the first SCC or the second SCC.
