<p>PROBLEM TO BE SOLVED: To efficiently and smoothly communicate the information of high priority regardless of the frame length of transmission signals. SOLUTION: In a header compression part 401, only header information is compressed and the header unit of a single header is generated. Then, in an identification bit insertion part 402, an identification bit for identifying the header information and data is inserted to MAC-PDU which is the data and a data unit is generated. The identification bit is efficient when the header information and the data can be identified. In this case, it is inserted only to the MAC-PDU which is the data. Also, when the header information and the data can be identified, the identification bit can be added to the header (506) as well. Then, in a frame assembly part 403, a frame is assembled by using the header unit (506) and the data unit (508a-508d). Thus, the frame is reconstituted.</p> |
