METHOD AND APPARATUS FOR DATA TRANSMISSION OF RADIO LINK CONTROL LAYER IN A MOBILE COMMUNICATION SYSTEM

摘要

Disclosed is a method and apparatus for transmitting data of a Radio Link Control (RLC) layer in a mobile communication system. Before an RLC SDU stored in a transmission buffer is discarded, a status report for checking a reception status of a receiving side is requested by a polling trigger either when transmission of the RLC SDU has not been completed, or when an RLC SDU discard timer for the RLC SDU approaches the expiration time, thereby enhancing the data transmission performance of the RLC layer.
