Allocation algorithms for PRIMO system

This paper proposes an architecture for the LL, MAC and PHY layers for a multicellular wireless system, which allows for a cross layer interaction. The PHY layer is assumed to implement an OFDM modulation, which is used at the MAC level to realize an hybrid FDMA/TDMA medium access. The complete reuse of the available resources among neighboring cells is the most challenging assumption, which brings the need for a smart resource allocation. Following a cross layer perspective, the radio resources are efficiently allocated to the different flows using information coming from the PHY layer. Each base station performs the allocation without explicit coordination with other cells, thus resulting in a distributed, dynamic allocation. Three different algorithms are presented and discussed. They are also compared with static FDMA, TDMA and random allocations.
