Abstract
An apparatus and method transmits data in a communication system. A buffer descriptor (BD) generator generates a BD making reference to constituent elements constituting a MAC protocol data unit (PDU), if there is a medium access control (MAC) service data unit (SDU) to be transmitted. A direct memory access (DMA) controller generates the MAC PDU from the MAC SDU according to the BD.
Claims20
A method for transmitting data in a communication system, the method comprising the steps of:
- generating a buffer descriptor (BD) making reference to constituent elements constituting second type data, if there is first type data to be transmitted;
- and
- generating the second type data from the first type data according to the BD.
A method for transmitting data in a communication system, the method comprising the steps of:
- detecting information indicating that a burst for transmitting data over a frame at a start point of the frame is allocated;
- upon detecting a need for transmitting a medium access control (MAC) service data unit (SDU) in the frame, generating a buffer descriptor (BD) making reference to constituent elements constituting a MAC protocol data unit (PDU);
- and
- generating the MAC PDU from the MAC SDU according to the BD.
