LTE Advanced: Carrier Aggregation
More InfoLess Info
Achieving the requirements set out in IMT-Advanced is even more challenging given the fragmentation of the available cellular radio spectrum, particularly in North America. Release 10 of the 3GPP LTE specifications—LTE-Advanced—delivers IMT-Advanced within practical spectrum constraints. It does this through the carrier aggregation feature. Carrier aggregation permits an LTE base station to group several distinct channels into one logical channel, thereby enabling very high peak traffic channel data rates. In this white paper, learn more about carrier aggregation including various configurations, software and hardware implications particularly related to UE as well as UE implementation and verification challenges.
