Abstract:
Inter-cell interference coordination (ICIC) is considered to be a promising technique for Long Term Evolution (LTE) to increase spectral efficiency. One efficient approach for ICIC is Soft Frequency Reuse (SFR). In this paper, we consider a call admission control in SFR-based systems and derive the call blocking and forced termination probabilities using a Markov chain analysis. In addition, SFR with spectrum handoff, called S-SFR, is proposed. Numerical results show that the analytic derivations are valid, and the proposed scheme outperforms the SFR scheme without spectrum handoff for the forced termination probability.
