Abstract

A method for determining threshold signal power for a switching control module of a TDD switching sub-system includes setting a threshold signal power to a first value, wherein the threshold signal power is compared to a measured signal power of a downlink path signal of a telecommunication system from a measurement receiver; determining a first downlink signal time using the first value; adjusting the threshold signal power to a second value; determining a second downlink signal time using the second value; determining a difference between the first and second downlink signal times; when difference between the first and second downlink signal times does not exceed a predetermined threshold, determining whether the second downlink signal time corresponds to a valid downlink signal time; when second downlink signal time corresponds to a valid downlink signal time, setting a fixed threshold signal power for use during online operation of the switching control module.
