Abstract
A media access control (MAC) filtering method is provided. The MAC filtering method includes setting a variable of condition on a target frame to be re-transmitted, with a relay control logic; receiving data from a physical layer; storing the received data in a relay buffer; determining whether to re-transmit the receive data; monitoring a transmission state of a MAC control logic and transmitting the received data while the MAC control logic is not used, to prevent data collision, when as a result of the determination that the receive data needs to be re-transmitted; and storing information that the received data is being transmitted, into a transmit state memory in the MAC control logic, when the received data is transmitted.
