Patent number: 7295539Abstract: An apparatus and method for generating reference timings. Each of at least two Node Bs transmits a first channel signal for providing a reference timing and a second channel signal different from the first channel signal and a UE has a plurality of fingers for demodulating the first channel signals. A first timing generator receives an SFN of a reference Node B having a communication link established with the UE, selects a first channel FB timing from a reference finger, and generates an SFN reference timing based on the SFN and the selected first channel FB timing. A second timing generator generates a second channel FB timing to demodulate the second channel signal of the reference Node B from the selected first channel FB timing through offset control. A third timing generator generates an uplink channel FB timing having a predetermined offset from the second channel FB timing.Type: GrantFiled: April 30, 2003Date of Patent: November 13, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Sung-Chul Han, Joo-Kwang Kim, Chae-Man Lim
