We develop a new Media Access Control strategy, called Plane Cover Multiple Access (PCMA), that provides a means of allocating wireless bandwidth in a packet based cellular system. PCMA seeks to maximize the number of parallel transmissions among cells by defining virtual cells in which users transmit using a given reuse factor. By keeping the reuse factors low, system throughput can be maximiz...
Abstract In DS-CDMA cellular communications systems, the single frequency reuse is utilized and hence large co-channel interference is received from other cells. If the single frequency reuse is not utilized to reduce the other-cell interference, we will face the frequency allocation problem, similar to FDMA systems. In this paper, we divide the available wide frequency band into several narrow...
With rapid increase of smartphone shipments and increasing popularity of wireless multimedia applications cellular networks are driven to capacity limits. How to effectively increase network capacity and improve user quality of experiences (QoE) are the subjects of a large body of research. Heterogeneous network structure, small cell deployment, massive MIMO and advance frequency resource manag...
