The first step is cell search procedure for a user terminal in TD-LTE. It’s the premise of the establishment of a communication link between the user terminal and the base station. To detect PCI correctly plays a crucial role in the cell search procedure, and it also affects the mobility of the user terminal. It’s a problem that is worth studying how to determine the PCI planning in TD-LTE. This article first briefly introduces the PCI parameter and the cell research procedure, and specifies the PCI is the important parameter for LTE, and then describes the planning principles of the parameter. Finally, it specifies the suggestions and situations of the PCI planning in test network of TD-LTE.
