METHOD OF TRANSMITTING AND RECEIVING A CONTROL INFORMAION IN A WIRELESS SYSTEM

摘要

PURPOSE: A method for transceiving control information in a wireless communication system is provided to include masked CRC to control information through masking indicator in base station, thereby preventing a terminal to recognize control information transmitted from a terminal to the other terminal as the information is transmitted to itself. CONSTITUTION: A base station performs masking of a CRC(Cyclic Redundancy Check) through a RAID(Random Access ID) for ranging and masking indicator 0b0001. The base station transmits a CDMA(Code Division Multiple Access) allocation A-MAP(Advanced-MAP) IE(Information Element) including the 16-bit masked CRC to a terminal. After the CDMA allocation A-MAP IE decoding, the terminal calculates the 16-bit masked CRC through a cyclic generator polynomial. If 0 does not come out as a masking result of a MCRC, the terminal ignores the CDMA allocation A-MAP IE.
