<p>A method and system for transmitting data by enhanced media access control are provided in present invention. When multicarrier and enhanced media access control technology are applied simultaneously in a Low Chip Rate Time Division Duplex (LCR TDD) system, the enhanced media access control Protocol Data Unit (PDU) structure with an expanding transmission sequence number (TSN) field is used for transmitting data, wherein the expanding TSN field includes N bits information, N>6. Application of the present invention can increase a numbering range of the TSN field, and can solve the problem that the reception end cannot distinguish between a new reordering PDU and a retransmitted reordering PDU, without reducing a transmission window, i e a peak value velocity of data transmission is ensured.</p> |
