<p>PURPOSE:To attain efficient control so as not to cause excess/shortage in a reception side buffer by adding an accumulated length to a transmission permission capacity to form a new permissible value when confirming information is received together with the accumulation length information from a reception node and sending a value excluding the accumulated length confirmed as the new accumulated length information from the next information. CONSTITUTION:The accumulation length information LL is extracted from a return frame received in a reception buffer R1BUF via a frame reception processing section REC 1 and outputted to a transmission sequence control section SQCTL-S as information 14. Further, a check section FCSCHK applies FCS operation from an output of the frame reception processing section REC 1 and sends the result as information 15 to the section SQCTL-S. When the result of FCS operation is OK and a retransmission request bit is '0', a command 16 making the data of a transmission data memory MEM-S ineffective is sent to a table SQTBL and when the level is '1', the information of the memory MEM-S represented by the LL coincident with the accumulated information (L+1) of the reception information length or a value larger than it and closest thereto to a node B again.</p> |
