Patent ID: 7643540

Claim:
A communication device adapted for receiving pilot bit patterns in a mobile communication system comprising: means for receiving pilot bit patterns through a physical channel having a radio frame with 15 slots, each slot including pilot bits having a length N pilot , where 2≦N pilot ≦16, wherein pilot bit patterns included in the 15 slots of the radio frame includes at least two of the following pilot bit patterns: 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); and means for performing at least one of a frame synchronization or channel estimation based on the received pilot bit patterns.
