Abstract
This paper proposes a decentralized algorithm for
interference coordination in LTE-A networks, based on the
exchange of information (pricing) at control plane level. In our
approach, every user equipment (UE) report the maximum
modulation and coding scheme (MCS) that can be used within
several sets (sub-bands) of available resource blocks, along with a
parameter (cost) that measures the MCS degradation due to the
transmission from an interfering neighbor. Through the
exchange of pricing messages, the higher costs are distributed to
the dominant interferers; and the selection of the MCS and
operational sub-band is based on the current link conditions
along with the received pricing messages. We evaluate the
algorithm in a cellular area covered by a macro base station
(MBS) and multiple active femtocells. We also measure the
degradation due to the quantization of the exchanged cost values.
The results demonstrate significantly enhanced performance as
compared to the non-coordinated case.
