Abstract
With the growing demand for new blend of applications,
the user’s dependency on the Internet is increasing day
by day. Mobile Internet users are giving more attention to their
own experience, especially in terms of communication reliability,
high data rate and service stability on the move. This increase
in the demand is causing saturation of existing radio frequency
bands. To address these challenges, many researchers are finding
the best approach, Carrier Aggregation (CA) is one of the newest
innovations which seems to fulfil the demands of future spectrum,
CA is one the most important feature for Long Term Evolution -
Advanced. In direction to get the upcoming International Mobile
Telecommunication Advanced (IMT-Advanced) mobile requirements
1 Gb/s peak data rate, the CA scheme is presented by 3GPP to
sustain high data rate using widespread frequency bandwidth up to
100 MHz. Technical issues containing the aggregation structure, its
implementation, deployment scenarios, control signal technique and
challenges for CA technique in LTE-Advanced, with consideration
backward compatibility are highlighted. Performance evaluation in
macrocellular scenarios through a simulation approach shows the
benefits of applying CA and low-complexity multi-band schedulers
in service quality and system capacity enhancement. The Enhanced
multi-band scheduler is less complex than the General multi-band
scheduler and performs better for cell radius longer than 1800 m (and
a PLR threshold of 2%).
