Managing secondary cell connections in unlicensed spectrum

An apparatus for wireless communication on a secondary component carrier in unlicensed spectrum in a wireless communication network using carrier aggregation, the apparatus comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor,
• wherein the at least one processor is configured to:
• monitor a downlink radio link quality of a secondary cell operating in the unlicensed spectrum at a mobile device for an event indicating failure of a communication link over the secondary component carrier with the secondary cell;
• detect a first event based on the downlink radio link quality;
• and
• declare a failure state of the secondary cell in response to detecting the first event, during which the mobile device adjusts operation related to the secondary component carrier in the unlicensed spectrum.

An apparatus for wireless communication on a secondary component carrier in unlicensed spectrum in a wireless communication network using carrier aggregation, comprising:

• means for monitoring a downlink radio link quality of a secondary cell operating in the unlicensed spectrum at a mobile device for an event indicating failure of a communication link over the secondary component carrier with the secondary cell;
• means for detecting a first event based on the downlink radio link quality;
• and
• means for declaring a failure state of the secondary cell in response to detecting the event, during which the mobile device adjusts operation related to the secondary component carrier in the unlicensed spectrum.

A non-transitory computer-readable medium storing computer executable code for wireless communication on a secondary component carrier in unlicensed spectrum in a wireless communication network using carrier aggregation, comprising code for causing a computer to:

• monitor a downlink radio link quality of a secondary cell operating in the unlicensed spectrum at a mobile device for an event indicating failure of a communication link over the secondary component carrier with the secondary cell;
• detect a first event based on the downlink radio link quality;
• and
• declare a failure state of the secondary cell in response to detecting the first event, during which the mobile device adjusts operation related to the secondary component carrier in the unlicensed spectrum.
