Abstract

Carrier aggregation and dual connectivity allow a user device to communicate with one or more base stations on multiple component carrier frequencies. When it is determined that the user device should handover to a new base station, the user device performs a substantial portion of the needed handover operations with the new base station using only one of the component carrier frequencies. Meanwhile, the user device maintains data communications with the original base station on the remaining component carrier frequencies.

First claim

What is claimed is:

1. A base station, comprising:
a first radio configured to communicate with a user equipment over a first channel;
a second radio configured to communicate with the user equipment over a second channel; and
a processor and/or one or more circuits, coupled to the first radio and the second radio, configured to:
exchange data with the user equipment over both the first channel and the second channel during a normal operation mode;
analyze the data; and
