Abstract

In the future wireless networks, there can be many network entities with different sizes of cells with different level of transmit power to achieve different level of QoS, which we call "heterogeneous network". The object of this paper is to study on performance of MIMO-relaying scheme for the relay-based scenario in heterogeneous network. We apply the diversity set decision, which is defined as the set consisted of BS and RSs selected by MS, and PF-ZFBF with greedy algorithm for selecting MS served by BS or RS to system level simulator based on IEEE 802.16m type TDD-OFDMA downlink. The performance of MIMO-relaying scheme is evaluated in terms of cell throughput and service coverage at 64 kbps user throughput requirement. The cell throughput of cases with relay shows the maximum cell throughput of 21% compared to case without relay. The cases with relay provide higher service coverage than the case without relay.
