Idle Signal Multiple Access (ISMA) system is known to obtain high throughput in the situation that a number of terminals transmit data packets to a base station over a common radio channel. In the system, the base station broadcasts signals which inform all terminals channel status of idle or busy. Each terminal is allowed to transmit a packet, only when it receives an idle signal. However, capture effect and propagation delay cause unfairness of local throughput depending on the distance from the base station. In this paper, we propose ISMA which broadcasts multiple idle signals to decrease unfairness of local throughput without power control. Performance of local throughput and total throughput are analyzed. It is shown that unfairness of local throughput due to distance decreases without decreasing total throughput.
