Abstract
A communication environment with carrier aggregation (CA) is disclosed in which a UE is configured for communication at a first time with a first network node via a primary component carrier (PCC) and a second network node via a secondary CC (SCC). At a second time, the UE is configured for communication with a third network node via the SCC at a second time. The UE maintains communication with the first network node via the PCC without triggering handover at the UE during the establishing communication with the third network node.
Claims80
A method for wireless communication, comprising:
- communicating at a first time, by a user equipment (UE), with a first network node via a first primary component carrier (PCC) and a second network node via a secondary CC (SCC);
- establishing communication, by the UE, with a third network node via the SCC at a second time following the first time;
- and
- maintaining communication with the first network node via the first PCC without triggering handover from the first network node via the first PCC to another network via a second PCC at the UE during the establishing communication with the third network node at the second time or between the first time and the second time.

A method for wireless communication, comprising:
- configuring a user equipment (UE) with a first primary component carrier (PCC) for communication with a first network node at a first time and a secondary CC (SCC) for communication with a second network node;
- configuring the UE with the SCC for communication with a third network node at a second time after the first time;
- and
- configuring the UE to maintain communication with the first network node via the first PCC during the configuring the UE for communication with the third network node at the second time or between the first time and the second time, wherein handover from the first network node via the first PCC to another network node via a second PCC is not performed for the UE while the UE communicates with the first network node via the first PCC.
