Abstract
The present invention allows efficient data compression when the contents of the control fields of packets are the same. An identity flag is substituted for a control field when the control field of an already-transmitted packet signal is identical to the control field of a packet signal which is to be newly transmitted. When non-identical, a non-identity flag is inserted to the control field. Thus, by using a larger number of small data format when identical control fields are transmitted consecutively, the data length of the control fields can be shortened.
