Problems solved by technology

[0005] 1. The total downlink power of the cell is equally divided by the carrier. Compared with single-carrier networking, the downlink power that can be used by various services has changed from being limited by the total downlink power of the base station to being limited by dividing the total downlink power of the base station by the number of carriers, resulting in The ability to support services with large power requirements is poor, and it is easy to cause network problems such as "fragmentation" of power resources and insufficient downlink coverage
[0006] 2. The interference of dedicated channels at the edge of the cell has not been controlled. The multi-frequency cell greatly reduces the mutual interference level of the common channel of the cell, but the mutual interference level of the dedicated channel at the edge of the cell has not been improved.
[0007] The above two reasons limit the performance potential of the multi-frequency cell networking of the TD-SCDMA system

Embodiment Construction

[0013] The method of the present invention will be described in further detail below by introducing a specific embodiment in conjunction with the accompanying drawings. Such as figure 2 Shown: the multi-frequency point cell networking method of the present invention is illustrated by taking N=3 as an example. The system implementing this method includes a network and a terminal. The network includes 3 multi-frequency cells CELL A, CELL B, and CELL C. The service channel of each cell is set up at the main frequency point and / or the secondary frequency point, and the total is F1, For F2 and F3, the adjacent multi-frequency cells select different carriers as the main frequency points, as shown in the figure: the main frequency points of CELL A, CELL B, and CELL C respectively select F1, F2 and F3, and at the same time make any multi-frequency The downlink transmit power of the primary frequency of the frequency cell is always not less than the downlink transmit power of any sec...

Abstract

The present invention relates to the wireless communication technology field, especially relates to a net method of TD-SCDMA (time-division synchronous code division multiple access) system multi frequency point district. The system includes a network and a terminal, the network includes a plurality of multi frequency point districts. A service channel of the district is built in a main frequency point and / or an assist frequency point, and adjacent multi frequency point districts select different carrier waves as the main frequency point. A downlink emission power of the main frequency of any multi frequency point district is set always not smaller than the downlink emission power of any assist frequency in the multi frequency point district. The inventive method can reduce effectively mutual interference at district peripheral dedicated channel between districts, at the same time has a strong service sustaining power for large power demand, and has wide downlink cover.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for networking a TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system multi-frequency cell. Background technique [0002] The commercial TD-SCDMA network requires the balance of capacity, coverage, service diversity and system efficiency to achieve the goal of maximizing customer investment efficiency. In the current TD-SCDMA commercial network, the technology of multi-frequency point cell is widely used. [0003] Common channels of multi-frequency cells, including Physical Random Access Channel (PRACH), Fast Physical Access Channel (FPACH), Primary Common Physical Control Channel (PCCPCH), Secondary Common Physical Control Channel (SCCPCH), Uplink Pilot Channel ( UpPCH), downlink pilot channel (DwPCH), etc. are only configured on the main frequency point. Dedicated channels can be established either on the primary frequency point or...
