Patent ID: 8717921

Claim:
A receiving apparatus configured to receive data transmitted from a transmitting apparatus by using retransmission control of a hybrid automatic repeat request scheme, the receiving apparatus comprising: a management unit configured to manage a target error rate in a target number of retransmissions; a measurement unit configured to measure an initial transmission rate of the data in the transmitting apparatus; and a calculation unit configured to calculate a target value of a reception rate of the data in the receiving apparatus by Equation 1A, where Pt denotes the target error rate and is an error rate value within a range of zero to 1, Nt denotes the target number of retransmissions and is a finite number equal to or greater than zero, TPUT init denotes the initial transmission rate of the data in the transmitting apparatus and is a positive, non-zero, finite throughput rate measured as packets transmitted per unit of time, and TPUT denotes the target value of a reception rate of the data in the receiving apparatus and is a positive, non-zero, finite throughput rate measured as packets transmitted per unit of time, TPUT = TPUT init Nt + Pt + 1 . [ Equation ⁢ ⁢ 1 ⁢ A ]
