Abstract

In this paper, we present a coordinated multicast scheme via a relay station (RS) over a single frequency network (SFN). According to the type of feedback information delivered from the RS to the adjacent base stations (BSs) involved in the coordinated multicast, the schemes are classified into the phase coordination multicast based on the RS (PCMR) and the vector coordination multicast based on the RS (VCMR). For the performance analysis, we derive the mathematical upper bound of an achievable rate from the BSs to the RS for the coordinated multicast based on RS. Through this analysis, we demonstrate that the PCMR and the VCMR achieve more gains over the noncoordinated multicast in terms of the number of RS antennas, the number of adjacent BSs, and the number of BS antennas. Through simulation, we derive a range of distances between the home BS and the RS, the number of users, and the number of user antennas, providing evidence that the RS-based multicast outperforms the conventional multicast.
