Abstract
Apparatus and methods are disclosed for determining a tolerable propagation delay between a repeater and a base station in a communication system. In one embodiment, a tolerable length of fiber optic cable between a repeater and a base station is determined. More particularly, a desired search window size in time is determined. A maximum fiber optic cable delay value is determined based on the desired search window size. Also, a ratio value of fiber optic cable delay value to fiber optic cable length is then determined. The tolerable length of the fiber optic cable is then determined based on the maximum fiber optic cable delay value and the ratio value.
