Abstract:
1. A method for adjusting a transmission rate of a wireless communication system comprising a transmitter and a receiver, the method comprising: counting a number of first transmitted packets within a predetermined time interval, the first transmitted packets being transmitted by the transmitter at a first transmission rate; counting a number of first acknowledgement packets received by the receiver, each of the first acknowledgement packets representing a successful transmission of one of the first transmitted packets; counting a number of second transmitted packets within the predetermined time interval, the second transmitted packets being transmitted by the transmitter at a second transmission rate, the second transmission rate being lower than the first transmission rate; counting a number of second acknowledgement packets received by the receiver, each of the second acknowledgement packets representing a successful transmission of one of the second transmitted packets; judging whether a first relationship between the number of first transmitted packets and the number of first acknowledgement packets satisfies an increment criterion; judging whether the first transmission rate exceeds a maximum transmission rate; increasing the first transmission rate if the first relationship satisfies the increment criterion and the first transmission rate is not above the maximum transmission rate; judging whether a second relationship between the number of second transmitted packets and the number of second acknowledgement packets satisfies a decrement criterion; judging whether the second transmission rate is below a minimum transmission rate; and decreasing the second transmission rate if the second relationship satisfies the decrement criterion and the second transmission rate is not below the minimum transmission rate.
