Adaptive Transmission Scheme According to the User Location

This paper proposes an adaptive cooperative scheme in the cell boundary. The user location and the suitable cooperative transmission scheme are considered in the proposed scheme. If the user is located in the cell boundary, the quality of communication is degraded. Two base stations are used to obtain diversity in the conventional schemes. But the quality of communication is not sufficiently improved because the user is still distant from the base stations. So, the scheme is proposed that the relays and the adaptive cooperative scheme are used considering the location of the user. By the simulation, it is proved that the proposed scheme is better than the conventional scheme.
