Abstract:
A user equipment (UE) configured to connect to a network and operate in a carrier aggregation mode and a single carrier mode performs methods to select optimal component carriers. The methods include determining that a primary component carrier is operating less optimally than a secondary component carrier, sending an indication to the network that the primary component carrier is operating less optimally than the secondary component carrier, acquiring the secondary component carrier as a target primary component carrier and operating with the secondary component carrier as the target primary carrier component. In one exemplary embodiment, the indication is declaring a radio link failure (“RLF”) between the UE and the network. In another exemplary embodiment, the indication is a measurement report send to the network that triggers a handover procedure for the UE.
