Introduction
 Resent years have seen a tremendous increase in the number of mobile
users.
 Global mobile phone penetration increasing from 20 percent in
2003 to 67 percent in 2009.
 This growth has affected wireless access networks (WANs), which are
already large energy consumers within the information communication
technology (ICT) domain.
 Base stations account for up to 90 percent of a WAN’s power
consumption.
 A thorough study of a base station’s power consumption can help us to
develop guidelines for reducing these networks’ power consumption.
LTE-Advanced functionalities
 LTE-Advanced introduces three new functionalities:
 carrier aggregation,
 heterogeneous networks,
 (MIMO) support -extended multiple-input, multiple-
output.
 Note:
The first two releases (release 8/9) are known as LTE.
Release 10, also known as LTE-Advanced.
LTE And LTE Advanced
 let devices adaptively change modulation
 coding rate
 bandwidth to enhance channel quality.
 It supports bandwidths from roughly 1 to 20 MHZ
 Note:
 This bandwidth can be further extended in LTE-Advanced by carrier aggregation, which lets the base station
transmit multiple LTE carriers, each with a bandwidth of up to 20 MHz.
LTE And LTE Advanced (cont.)
 Both LTE (8/9) or LTE Advanced Supports
Heterogeneity (Macro Cells & Femto Cells )BS
 LTEAdvanced improves the handling of interference
between the different cells.
 LTE-Advanced enhances support for MIMO up to
eight transmit antennas.
Energy Efficiency in Wireless
Access Networks
 which base station type is most energy efficient (EE)
 different performance parameters: (bandwidth,
coverage, served users, and so on).
 define energy efficiency EE (∈ [0, ∞[) (in (km2
Mbps)/W) as
Energy Efficiency in Wireless
Access Networks
 Pel : the base station’s power consumption
(in watts)
 R : is the range (in km)
 B: is the physical bit rate by the base station (in Mbps)
 U is the number of served users
 The higher the EE, the more energy efficient the base
station is.
Base Stations
Base Stations Types:
Macrocell : Which is the Bigger than
the base station of Femtocell , Serve
more users and has higher Range
Femtocell :is much smaller than a
macrocell base station and is
comparable to the base station of a
Wi-Fi access point.
carrier aggregation
 We investigate how adding carrier aggregation
influences energy efficiency.
 To obtain the results in the Figure , we determine
the power consumption, range, and bit rate as
discussed earlier.
 The number of served users is fixed.
 only one bandwidth (5 MHz).
 We then calculate EE .
Results (LTE & LTE Adv.)
Curve Notes
 Carrier Aggregation Decrease the power Consumption
for Both Femtocell and Macro Cell .
 Higher modulation scheme or coding rate results in
lower EE because a higher modulation scheme and
coding rate lead to a shorter range for a higher bit rate.
Heterogeneous Deployments
 suggests that a femtocell base station is less energy
efficient than a macrocell basestation. However, this
isn’t always the case.
 compares the energy efficiency of LTE-Advanced
macrocell and femtocell base stations as a function of
attainable bit rates.
Results
Curve Notes
 which base station type is most energy efficient:
 >20 Mbps, the macrocell base station is the most
energy efficient
 due to its longer range and higher number of served
users (despite its higher power
consumption)
 5—20 Mbps Ambiguous
 < 5 Mbps femtocell is more Energy Efficient
Suggested Solution
 We can find this optimal combination by :
1 - placing macrocell base stations to cover the area
first.
2 - then femtocell base stations to provide coverage in
the coverage holes.
3 - Then we can extend the macrocell base station’s
capacity as needed using femtocell base stations in the
coverage cell of the macrocell base stations.
 financial support of the iMinds project “Green Wireless Efficient City Access Networks” (GreenWeCan).
MIMO
 We consider a bit rate of 2.8 Mbps in a 5-MHz
channel.
 We use single-input, single-output(SISO) — that is,
only one transmitting and one. receiving antenna — as
a reference scenario.
MIMO Results
Curve Results
 shows that the more transmitting and receiving
antennas, the higher the EE. For
the macrocell base station.
 EE increases up to 433 percent when using 8×8 MIMO.
 Future networks can benefit from MIMO,and should
use the highest possible MIMO mode.
Conclusion
 We saw that LTE-Advanced’s carrier aggregation and
MIMO improve networks’ energy efficiency up to 400
and 450 percent, respectively.
 Future work :
Study how the features investigated here will perform in
terms of energy efficiency when applied on an actual
network.

Editor's Notes

  • #6: Carrier Aggregation : That is, when no carrier aggregation is used, the user device will receive one carrier. When using carrier aggregation, it is possible to send not just one carrier but multiple carriers to the users, which results in a higher bit rate.6 A carrier, in this context called a component carrier, contains the data to be sent.
  • #7: Note: LTE-based heterogeneous networks are typically two-layered networks with macrocell (eNodeB) and femtocell (home-eNodeB) base stations.
  • #10: Note: A femtocell base station is much smaller than a macrocell base station and is comparable to the base station of a Wi-Fi access point. As Figure 1 shows, the power-consuming components thus differ from those of a macrocell base station.
  • #14: Note: we first defined the bit rate for the aggregation of one to five component carriers with equal bandwidths. We considered all possible bandwidths. Next, for each possible bit rate and each base station type, we chose the most energy-efficient solution.
  • #20: Note: Pel is 2 times higher, while R is 3 times higher, resulting in an EE that is 5 times higher. For the femtocell base station, EE increases up to 454.6 percent (or 5.5 times).
  • #21: MIMO: Step for :extended multiple-input, multiple-output
