Abstract: A frame transmission controlling apparatus includes: a list configuration unit managing a parameter related to a gate control; a cycle timer unit managing a start timing of a cycle; a list executing unit performing the gate control based on the parameter, wherein the list executing unit includes: a cycle executing state machine setting an expiration time of at least one section included in the cycle, checking gate operation information corresponding to a list pointer indicating the at least one section, and performing a control corresponding to the gate operation information; a delaying state machine deducting and updating the expiration time by a predetermined unit; a cycle holding state machine generating a control signal indicating stopping transmission in MAC; and a cycle releasing state machine generating a control signal indicating resuming the transmission in MAC.
