Patent ID: 7062290

Claim:
A method of transmitting a cell ID code in a mobile communication system, in which a primary cell is recognized by receiving a primary cell ID code from a terminal, comprising: receiving a plurality of temporary cell ID codes from a control center; measuring a power of a Common Pilot Channel (CPICH) of a cell; selecting a temporary cell ID code with a strongest power of the CPICH of the cell; checking whether the selected temporary cell ID code has a length of 16-bits; checking whether feedback information (FBI) bits are 2 bits, if the detected temporary cell ID code has the length of 16-bits; puncturing two ‘0’ bits in the selected temporary cell ID code to generate a primary cell ID code having one of the following bit configurations with the punctured bits indicated in parentheses: A: (0)000 (0)000 0 000 0 000 B: (0)000 (0)000 1 111 1 111 C: (0)101 (0)101 0 101 0 101 D: (0)101 (0)101 1 010 1 010 E: (0)011 (0)011 0 011 0 011 F: (0)011 (0)011 1 100 1 100 G: (0)110 (0)110 0 110 0 110 H: (0)110 (0)110 1 001 1 001; and transmitting the selected 16-bit temporary cell ID code through a 2-bit FBI field of the first 8 slots of one radio frame and transmitting the 14-bit punctured primary cell ID codes through a 2-bit FBI field of the last 7 slots of the radio frame.
