Abstract:
1. A method, comprising: operating a user equipment (UE) to initiate monitoring of a control channel associated with a particular component carrier for determining if the user equipment is scheduled by the control channel associated with the particular component carrier for discontinuous reception; and in response to determining that the user equipment is not scheduled, terminating the monitoring of the control channel associated with the particular component carrier; where in response to on occurrence of a trigger event being detected by the user equipment, where the trigger event comprises the user equipment detecting that the user equipment has been scheduled by the control channel of the particular component carrier by an amount that exceeds a threshold amount for the discontinuous reception, the UE activates the monitoring of a physical downlink control channel (PDCCH) associated with another component carrier for the discontinuous reception; confirming that the user equipment has activated the monitoring of the PDCCH associated with the another component carrier with signaling between the user equipment and a base station that transmits the another component carrier; initiating, by the UE in response to the UE activating the monitoring of the PDCCH associated with the another component carrier for discontinuous reception, a counter;
