Abstract:
LTE-Advanced extends the capabilities
originally defined in LTE within the 3GPP and Carrier
Aggregation (CA) is the most significant, although
complex, improvement provided by LTE-Advanced.
Bandwidths from various portion of spectrum are
logically concatenated or “aggregated” resulting in a
virtual block of a much larger band, enabling increased
data throughput. The aim of this paper is to present an
introduction of CA in LTE-Advanced system, including
current 3GPP status on CA technology, configuration
and deployment scenarios and Physical, MAC and RRC
(Radio Resource Control) Layers aspects of Carrier
Aggregation.
