Sparsity Modulation for 6G Communications

Past decade has witnessed the tremendous increases in data throughput and the number of connected nodes, and recent studies have also foreboded these increases in next generation networks. These tremendous increases will undoubtedly result in increasingly stringent requirements of spectral efficiency and energy efficiency. To meet these two requirements, sparsity modulation, such as index modulation, media-based modulation, RIS-based/reflecting modulation, OTFS, and subcarrier number modulation, attracts researchers’ attention in recent years. Different from conventional amplitude-phase modulation schemes, sparsity modulation employs one or more modulation dimension(s) in addition to the classic amplitude-phase constellation diagram, so as to form a higher-dimensional modulation scheme, which considerably enhances the spectral efficiency under proper system configurations.
By sparsity modulation, only a subset of media resources or functional blocks will be activated to form a unique activation pattern. Consequently, the activation pattern per se can be used to modulate extra bit stream in addition to the bit stream modulated by data constellation symbols. As a paradigm in its infancy, there are still a large number of open research questions awaiting solutions and further research activities are of high importance to finally promote sparsity modulation to the practical implementation stage. Apart from theoretical research, the concerns of practical implementation are required to be addressed.
In light of the aforementioned advantages of applying sparsity modulation for 6G communications and the remaining research problems, this feature topic aims to bring together leading researchers in both academia and industry from diversified backgrounds to attract original and high-quality publications addressing the theoretical and practical issues related to sparsity modulation. Extended versions of papers published in conferences, symposiums, or workshop proceedings are encouraged for considerations.
