Problems solved by technology

[0003] The existing LTE common-mode methods all adopt a unified architecture and a deeply integrated design method, which is deeply compatible with FDD and TDD functions on the CCU and BPU. However, the existing methods will cause some problems: First, it is implemented in software and hardware ...

Embodiment Construction

[0018] The technical solution of the present invention provides a kind of LTE common mode method, see figure 1 Explain that this common mode method is to perform FDD / TDD fusion on the CCU (Central Control Unit) to realize LTE common mode, and the BPU (Baseband Processing Unit) uses existing single-mode FDD / TDD products (including software and hardware). This common mode method consists of the following steps:

[0019] Step 1: On the OAM (Operation Management and Maintenance) side, use the existing design of single-mode LTE to undertake the relevant functions of FDD / TDD respectively, and abstract an adaptation module to solve the compatibility problem in the incompatible place. The LMT (Local Maintenance Terminal) used in conjunction with OAM also uses some parameter configuration and management functions. According to the principle of integrating base station-level functions and independent cell-level functions, the configuration table items are redesigned.

[0020] Step 2: I...

Abstract

The invention provides a single mode LTE-based method and a single mode LTE-based system for realizing a common mode LTE base station. The method and the system of the invention abstract a base station-level function module on a CCU to process FDD/TDD base station-level functions on the basis of using existing LTE technology and products, and simultaneously perform the same processing on the OAM and GTPU, and add an adaptation process in a cell-level function so as to solve a compatible problem. An LMT follows a principle that base station-level tables are fused and cell-level tables are independent to classify parameter configuration tables according to the base station-level functions and the district-level functions. The BPU(FDD plus TDD) maintains the existing hardware and software design, and connects with a corresponding FDD/TDD RRU to realize a base-band processing function. By using the existing technology and the product, the method and the system of the invention realize a function of the common mode LTE base station, greatly reduce the difficulty of existing LTE common mode technology and corresponding cost.

Description

technical field [0001] The invention belongs to the communication field, and relates to a method and system for realizing a common-mode (FDD+TDD) LTE base station based on single-mode LTE. Background technique [0002] LTE is divided into two modes, FDD and TDD. TDD is the 4th generation communication system independently developed by my country and has a large market demand in China. FDD is the communication system used by many countries in Europe and America. The two modes have their own advantages in terms of coverage and capacity. FDD can expand the uplink coverage, and the TDD frequency band can increase the downlink capacity. The FDD / TDD common mode enables operators to deploy TDD economically, forming complementary advantages with the FDD network, reducing the The coverage cost of TDD ensures the effective use of spectrum and improves the coverage area and network capacity of FDD / TDD. Because of this, the demand for FDD / TDD common-mode networking is relatively strong...
