Abstract
The abundance of unlicensed frequency resources in the mm-Wave frequency range, especially round 60 GHz bands, have a great potential to fulfill the increasing demands of high speed wireless applications. In mm-Wave wireless communication systems, directional transmission technologies become an inherent feature to compensate the high pathloss. The frame aggregation scheme is designed to maximize network throughput and efficiency for packet-based systems by grouping and transmitting multiple packets in a single channel access. In this paper, by jointly considering the benefits of directional transmission and frame aggregation, we propose a paradigm of parallel directional transmission, named cross talk MAC (CTMAC), for enhancing the spatial reuse of mm-Wave directional wireless networks. Enabled by its packet level channel access algorithm, CTMAC allows parallel transmissions even under the strongest interfered topologies to enhance the performance of the mm-Wave wireless personal area network. The numeric results show that the proposed CTMAC dominates the conventional scheme in nearly all scenarios. Especially, CTMAC outperforms the conventional scheme up to 2-fold with good antenna directivity.
