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.
Claims30
A method for wireless communication on a secondary component carrier in a wireless communication network using carrier aggregation, comprising:
- monitoring a downlink radio link quality of a secondary cell at a mobile device for an event indicating failure of a communication link over the secondary component carrier with the secondary cell;
- and
- 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.
An apparatus for wireless communication on a secondary component carrier in a wireless communication network using carrier aggregation, comprising:
- means for monitoring a downlink radio link quality of a secondary cell at a mobile device for an event indicating failure of a communication link over the secondary component carrier with the secondary cell;
- 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.
A computer program product for wireless communications in a wireless network, comprising:
- a non-transitory computer-readable medium having program code recorded thereon, the program code including:
- program code for causing a computer to monitor a downlink radio link quality of a secondary cell at a mobile device for an event indicating failure of a communication link over the secondary component carrier with the secondary cell;
- and
- program code for causing the computer to declare 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.
An apparatus configured for wireless communication, 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 at a mobile device for an event indicating failure of a communication link over the secondary component carrier with the secondary cell;
- and
- to declare 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.
