- W2319523818 abstract "Multicell cooperation requires much information exchange between base stations. To reduce backhaul overhead and feedback overhead, a distributed precoding method based on signal-to-leakage-and-noise-ratio maximization is proposed, which only needs the sharing of channel state information of interference channel and not the user data. It has a better performance compared with eigenbeaming and intercell interference nulling which are two extreme sides. To fully exploit feedback, we derive the expression of sum rate loss and find the optimal solution to minimize it by brute-force research. Simulation results show that the performance can be further improved through adaptively allocate bits relying on the relative strength between the desired and interfering signals within the cell." @default.
