The LTE-Advanced (LTE-A) system is currently under development to allow for significantly higher spectral efficiency and data throughput than LTE systems. In a wireless system based on orthogonal frequency division multiplexing (OFDM) with frequency reuse factor one such as LTE, the achievable cell spectral efficiency is often limited by the inter-cell interference or coverage shortage of base stations...
Cooperative joint transmission and detection algorithms have a high potential to increase the capacity of cellular radio systems. This paper investigates efficient network layer protocols to realize such cooperation over a heterogeneous, bandwidth-limited backhaul. Target systems are MIMO-OFDM cellular communication systems with flat hierarchy (no central unit), and we take 3GPP LTE as example. The...
