Performance analysis of a reuse partitioning technique for OFDM based evolved UTRA
2006 (English)In: 14th IEEE International Workshop on Quality of Service (IWQoS) / [ed] [sn], Piscataway: IEEE conference proceedings, 2006, 112-120 p.Chapter in book (Other academic)
Abstract [en]

The current 3GPP working assumption on the evolved universal terrestrial radio access (E-UTRA) physical layer is that it will be based on single carrier frequency division multiple access (SC-FDMA) for the uplink and orthogonal frequency division multiple access (OFDMA) for the downlink. According to the concept specification, inter-cell interference mitigation techniques applicable to SC-FDMA and OFDMA systems are expected to be the key radio resource management techniques for E-UTRA. In this paper we propose and analyze a simple reuse partitioning technique (assuming coordinated sub-carrier allocation in the cells) that is able to minimize inter-cell interference. We propose a model that is able to take into account that sessions dynamically enter and leave the system. Rigid sessions require a class-specific fixed number of sub-carriers, while elastic sessions can enter the system if a minimum number of sub-carriers is allocated to them. In this rather general setting we analyze the system performance in terms of the expected number of sub-carrier collisions, the session blocking probabilities and the signal-to-noise-and-interference ratio performance. We present numerical results on the various trade-offs between these measures that provide insight into the behavior of OFDM based cellular systems and help dimension the parameters of a reuse partitioned system.
