Patent ID: 7848393

Claim:
A method of transmitting pilot bit patterns for at least one of frame synchronization and channel estimation in a mobile communication system, the method comprising: transmitting at least one pair of pilot bit patterns on a physical channel having a radio frame with 15 slots, each slot including pilot bits having a length of N Pilot , where 2≦N Pilot ≦16, wherein the at least one pair of pilot bit patterns comprises any one of {C 1 , C 2 }, {C 3 , C 4 }, {C 5 , C 6 }, and {C 7 , C 8 } where C 1 =(100011110101100), C 2 =(101001101110000), C 3 =(110001001101011), C 4 =(001010000111011), C 5 =(111010110010001), C 6 =(110111000010100), C 7 =(100110101111000), and C 8 =(000011101100101).
