    Abstract: The present invention is directed to a communication terminal in a wireless communication network. The communication terminal includes a receiver configured to receive a first message comprising a media access control (MAC) frame at a first transmission rate from a communication device in the wireless communication network; a message generator configured to generate a second message in response to the received first message, the second message comprising a control response frame; and a transmitter configured to transmit the control response frame at a second transmission rate, wherein the second transmission rate is lower than or equal to the first transmission rate; and wherein the second transmission rate is dependent on a difference in qualities between downlink communication and uplink communication between the communication device and the communication terminal. Methods of modulating a message for transmission in the wireless communication network are also disclosed.
