In this article, a novel approach for mobile radio communications is proposed and analysed, which is promising for future 6G cooperative distributed MIMO systems. The fundamental idea is a new mechanism namely start stop bit method, which transmits bit sequences as the start/stop bits of a synchronized counter instead of transmitting the full encoded bit sequence itself. In that way, theoretically, we can transmit infinitely long data messages with only one bit for starting and one bit for stopping the counter. The value of the counter, as identified by the stop bit, is then used to reconstruct and remap the one and unique transmitted bit sequence. The start stop bit method is characterized by a high signal sparsity as only two bits are transmitted, independently of the bit sequence length for the message. Among the benefits of the start stop bit method are energy efficient data transmission, and effective distributed MIMO systems, which exploit the sparse inter cooperation area interference as well as the low processing complexity for the sparse precoder calculation. Moreover, for the next mobile wireless generation, we propose an advanced scheme of the start stop bit method which enhances its resource usage. We call the resulting method a sparse dMIMO system.
