Abstract

This paper presents a cellular reuse scheme using interference aware time division scheduling coupled with transmit power control. The proposed scheme supports a time reuse of one for interference insensitive users and a time reuse of 1/3 for interference sensitive users. Unlike traditional reuse partitioning, the proposed scheme provides a blind intercell power coordination mechanism for the interference sensitive users. Thus, when a cell transmits data to interference sensitive users, neighboring cells reduce their transmission power, which enables blind intercell coordination and aggressive time reuse. Simulations show that approximately 22% capacity increase can be achieved by the proposed scheme compared with conventional reuse planning.
