1. A user equipment, comprising:
a transmitter, which in operation, transmits at least one data packet within a transmitting window having a transmitting window size, the transmitting window size determining how many data packets are transmitted;
a receiver, which in operation, receives reception feedback including positive acknowledgements and negative acknowledgements regarding the at least one transmitted data packet; and
processing circuitry, which in operation, determines, based on at least the received reception feedback, whether to change the transmitting window size for the transmitting window to be used at least for transmitting further data packets,
wherein the processing circuitry, based on a number of the negative acknowledgements received by the receiver exceeding a predetermined threshold, determines whether to decrease the transmitting window size,
wherein the processing circuitry, in response to receiving the negative acknowledgements which are evenly distributed, determines to decrease the transmitting window size, and
wherein the processing circuitry, in response to receiving the negative acknowledgements which are continuous, determines to maintain the transmitting window size.
