Abstract:
1. A data transmitting method using adaptive coding of a physical layer of an asynchronous mobile communication system where a Serving Radio Network Controller (SRNC) consisting of a media access control (MAC) layer and radio link control (RLC) for transmitting channel data and a base station, connected to the SRNC with a wired interface, consisting of the physical layer being in charge of actual data transmission are included, comprising the steps of: (a) receiving transport blocks (TBs) and their RLC sequence numbers (SNs) from the MAC layer through the wired interface, and keeping the received TBs and their RLC SNs stored for a predetermined time after discarding one or more TBs whose RLC SN is overlapped with pre-stored TBs; and (b) adjusting a puncturing rate based on information on notifying acknowledgement, received from a remote counterpart, for previously-transmitted TBs, and applying the adjusted puncturing rate to the stored TBs in the middle of a preparing process for transmitting the TBs through a physical channel.
