Abstract :
Overload indicator (OI) and high interference indicator (HII) are two main approaches to mitigate inter-cell interference in long term evolution (LTE) system. Using OI or HII separately will incur inevitable shortcomings, therefore, in this paper, an OI&HII hybrid scheme is proposed for inter-cell interference coordination (ICIC) through signaling interaction between the two schemes. Instead of broadcasting OI message to all the neighboring cells, in the proposed scheme, the serving base stations (BS) just sends it to selected neighbors to inform them to adjust uplink transmission power. Simulation results show that this new scheme can effectively enhance the uplink throughput while reducing signaling overhead on the X2 interface at the same time.
