The efficient communication protocol of the asymmetric channel which has wider bandwidth of downlink than that of uplink has been proposed. However, this protocol was studied in an ideal environment, and an actual environment is not assumed. We are studying a method for adding uplink 1-bit error tolerance to this protocol. In this paper, we derive the effect on performance when error tolerance is added to the proposed method. The evaluation indicators are the number of transmission bits, delay, and throughput. We confirmed the effect on other indicators when any one of indicators was set to satisfy the desired performance, and that each indicator has a trade-off relationship. Furthermore, when we are setting parameter according to case of user, how much influence will occur on other indicators will be described with using an example of the network environment.
