The propagation delay measurement apparatus and method in a narrow band time division duplexing code division multiple access mobile communication system

摘要

In TDD mobile communication system, the present invention provides a method for measuring a propagation delay value of a frame transmitted to the Node B by the UE. Acquires synchronization with the Node B by the downlink pilot channel signal transmitted in a section of the downlink pilot time slot, the UE, the physical common channel signal transmission power of the physical common channel signal in the first time slot to determine the predicted round-trip propagation delay value T1 by comparing the received power of.
