Abstract
Interference coordination methods for Evolved-
Multimedia Broadcast/Multicast Service (E-MBMS) in Long-
Term Evolution Advanced (LTE-A) are presented. In this
paper, OFDM/OFDMA signals based on LTE parameters are
combined with Multipoint MIMO, Turbo codes and signal
space diversity methods. Different interference coordination
techniques, such as, Multipoint MIMO coordination, Fixed
Relay stations, adaptive frequency reuse and schedulers are
considered to evaluate the E-MBMS spectral efficiency at the
cell borders.
The system level coverage and throughput gains of
Multipoint MIMO system with hierarchical constellations and
Turbo-codes are simulated associated to the presence or not of
fixed relays and measuring the maximum spectral efficiencies
at cell borders of single cell point-to-multipoint or single
frequency network topologies. The influence of the relay
transmission power and cell radius in the performance of the
previous cellular topologies is also evaluated.
