Patent ID: 7486644

Claim:
A method of transmitting control information associated with uplink packet data transmission in a mobile communication system, the method comprising the steps of: generating a 16-bit user equipment identifier (UE-ID) specific cyclic redundancy check (CRC) by combining a CRC generated for detecting errors from the control information with a UE-ID for identifying a user equipment (UE) to receive the control information; generating 90 coded bits by adding the UE-ID specific CRC and 8 tails bits to 6-bit control information and encoding the added bits at a coding rate of 1/3; generating a 60-bit rate-matched block by rate-matching the coded bits according to a rate matching pattern representing positions of bits to be punctured among the coded bits; and transmitting the rate-matched block to the UE, wherein the rate matching pattern comprises {1, 2, 5, 6, 7, 11, 12, 14, 15, 17, 23, 24, 31, 37, 44, 47, 61, 63, 64, 71, 72, 75, 77, 80, 83, 84, 85, 87, 88, 90}.
