Abstract:
|
In the near future, an increase in cellular network density
is expected to be one of the main enablers for the newly introduced
challenging capacity goals. This development will lead to an increase
in the network energy consumption. In this context, we propose an
energy efficient dynamic scheme for HSDPA+ (High Speed Downlink
Packet Access-Advanced) systems aggregating several carriers. In the
proposed scheme the network adapts dynamically to the network traffic.
The scheme evaluates whether node-B deactivation is feasible without
compromising the user flow throughput. Furthermore, instead of progressive
de-activation of carriers and/or node-B switch-off, we evaluate
the approach where feasible combination of inter-site distance and number
of carriers is searched to obtain best savings. The solution exploits
the fact that re-activation of carriers might permit turning off the BSs
earlier at relatively higher load than existing policies, which provides the
highest energy saving. Remote electrical downtilt is also considered as a
means to reduce the utilization of lower modulation and coding schemes
(MCS) in the new extended cells. This approach promises significant
energy savings when compared with existing policies - not only for low
traffic hours but also for medium load scenarios. |
