| 摘要 | A communication device including: a processor configured to perform a wireless communication protocol including an upper layer and a lower layer, wherein the processor is configured to estimate, based on a round trip time measured at the upper layer in case of carrying out a retransmission control at the lower layer and a time taking for retransmissions at the lower layer, a first estimated round trip time, to estimate, based on the number of times of packet loss at the upper layer in case of carrying out the retransmission control at the lower layer, and the number of times of successful transmission at the upper layer being recovered by the retransmission control, a first estimated packet loss rate, and to obtain, based on the first estimated round trip time and the first estimated packet loss rate, a first estimated throughput in case of not carrying out the retransmission control. | ||

| 主权项 | 1. A communication device comprising: an antenna configured to perform a wireless communication; and a processor configured to perform a wireless communication protocol for the wireless communication, the wireless communication protocol including an upper layer and a lower layer; wherein the processor is configured to estimate, based on a round trip time measured at the upper layer in case of carrying out a retransmission control at the lower layer and a time taking for retransmissions at the lower layer, a first estimated round trip time in case of not carrying out the retransmission control, to estimate, based on the number of times of packet loss at the upper layer in case of carrying out the retransmission control at the lower layer, and the number of times of successful transmission at the upper layer being recovered by the retransmission control, a first estimated packet loss rate in case of not carrying out the retransmission control, and to obtain, based on the first estimated round trip time and the first estimated packet loss rate, a first estimated throughput in case of not carrying out the retransmission control. | ||
