Abstract:
1. A pilot power setting method for using in a femtocell which is operated in a closed mode to provide service to a user equipment (UE), wherein the pilot power setting method comprises: (a) establishing a communication link connecting the UE and the femtocell; (b) providing a command to the UE, which returns n items of path loss information to the femtocell in a pre-determined period according to the command, wherein n is a natural number which is greater than 1; (c) obtaining a maximum path loss information between the UE and the femtocell from the n items of path loss information in the pre-determined period; (d) obtaining a predicted pilot power according to the maximum path loss information; and (e) setting a pilot power of the femtocell according to the predicted pilot power; wherein before step (b) and after step (d), the pilot power setting method further comprises: (f) recording an operation time; and (g) determining whether the operation time is reached to a predetermined measuring time value, wherein if the operation time is not reached to the predetermined measuring time value, then the pilot power setting method repeats steps (b) and (c) to obtain another maximum path loss information in the next pre-determined period.
