Abstract: PROBLEM TO BE SOLVED: To suppress the probability of vagueness in the case of performing intermittent packet processing by performing medium access control layer processing corresponding to the start protocol data unit transmission of a receiver. SOLUTION: A medium access control layer controller MLC 190 determines the data back logs of buffers TXB0 and TXB1 and transmits a start protocol data unit(PDU) to a receiver 167. Further, the medium access control layer processing is executed as well corresponding to the transmission of the start PDU. Besides, the determined data back log is displayed on a medium access controller by a network layer 160. After the start PDU is transmitted, data transmission is stopped and a reception notice message from the receiver 167 is waited. At such a time, the reception notice message from the receiver 167 is controlled by a sub channel controller 185. Thus, wireless link protocol and dynamic partial echo management is executed to a processing orineted packet data communication system.

Abstract: PROBLEM TO BE SOLVED: To obtain a system and a device for executing a radio link protocol by deciding a data backlog by a medium access control layer controller, transmitting a start protocol data unit including a flag to a receiver and starting medium access control layer processing in accordance with the transmission of the start protocol data unit. SOLUTION: A medium access control(MAC) layer 155 operates as an interface together with a layer 3 (network layer) 160, a physical layer (layer 1) 165 (including a MAC layer transmitter 166 and/or a MAC layer receiver 167) and a management component 170. A MAC layer controller(MLC) 190 decides data backlogs for buffers TXB0 and TXB1 and transmits a start protocol data unit (start PDU) including a flag to the MAC layer receiver 167. Further, it stops data transmission after transmitting the start PDU and waits for a reception notification message from the receiver 167.
