Abstract: Allocation of CSI-RS or CSI pilot sequences among cells in a cooperative manner to reduce pilot inter-cell interference. Sequences in each cell occupy the same time slot, multiple subcarrier frequencies, and are orthogonal in time via properly chosen cyclic shifts. Sequences in multiple cells are chosen from a pool of non-orthogonal yet distinguishable sequences through their root indices. Exchanging root indices among cells allows a given cell to reconstruct sequences used in neighboring cells and to estimate interfering channels as the number of channel taps is usually limited, thus mitigating pilot contamination. Furthermore, a greedy selection algorithm to find combinations of sequences that further reduce the channel estimation mean-square-error is proposed.
Abstract: A material of alignment film, a method of fabricating a liquid crystal display panel, and a liquid crystal display panel are provided. The material of alignment film is obtained by mixing a polymerizable monomer in the polyamic acid solution, thus is easy to fabricate. The method of fabricating the liquid crystal display panel obtains an alignment film including a polyimide film and polymer protrusions located on a surface of the polyimide film by coating the material of alignment film on a substrate, and going through a series of processes; the alignment film can allow liquid crystal molecules arrange in vertical alignment and generate a pre-inclination angle, and a risk of the polymerizable monomer contaminating the liquid crystal molecules does not exist, so as to enhance quality of the liquid crystal display panel. The liquid crystal display panel has a simple structure and good alignment effect, and has excellent display quality.
