Abstract
Various hybrid division duplex (HDD) schemes have been proposed to maximize the performance of duplexing in cellular mobile communication systems. The HDD mode, however, still has problems of co-channel interference among TDD users since it can not reduce the interference from neighboring base stations (BS). We propose an extended region and time partitioning (ERTP) to mitigate the interference not only from mobile stations (MS) but also from BSs in neighboring cells. The timeslots in the whole frame are split into several minislots, and each cell is divided into as many regions as the number of minislots per timeslot. We also design an adaptive time slot allocation (TSA) scheme to assign users according to the function composed of estimated inter-cell interference. The computer simulations show our proposed ERTP architecture with the proposed TSA can enhance both the average throughput and the outage probability. © 2007 IEEE.
