| Abstract: | With the popularity of mobile terminals in recent years, people expect more convenient and more efficient wireless networks. Today's wireless networks are committed to providing characteristics such as efficiency, fairness and quality of service. However, in the long distance wireless network environment, these requirements are difficult to meet. We propose an uplink transmission scheme of the control terminal, which can perform long distance transmission and short distance transmission at the same time to improve the bandwidth utilization of the base station. Our proposal mainly solves the following problems: (1) how to get the distance of the terminal; (2) how to schedule the transmission of each terminal to improve the bandwidth utilization rate. |
