Example

[0070] The first embodiment provided by the present invention, as shown in FIG. 5, includes:

[0071] Step 11. In the directional antenna mode of the multi-carrier system, the primary and secondary sub-carriers are divided by a network planning base station controller (RNC), and determined by network initialization.

[0072] When dividing the sub-carriers of each sector, the principles followed are as follows:

[0073] Divide the sub-carriers in each sector into N groups that do not overlap each other according to the number of sectors in the multi-carrier system, and in each sector, select one of them as the main sub-carrier of the sector, and the other sub-carriers The carrier is used as the sub-carrier of the sector.

[0074] In order to more effectively reduce the inter-cell interference, the principles followed also include: adjacent sectors need to select different primary subcarriers.

[0075] Assume that as shown in Figure 6, each cell is divided into three sectors, and ea...

Abstract

The related flexible FDM method on directional antenna mode comprises: the RNC divides every sector into the main carrier and sub-carrier and determines the maximal emission power for sector according to business quantity; the BS determines the emission power for carriers, and communicates with user based on relative sub-carrier. This invention has well expansion, improves frequency source utility, and adjusts conveniently.

Description

technical field [0001] The invention relates to the communication field, in particular to a soft frequency multiplexing method. Background technique [0002] The next-generation mobile communication technology needs to support a variety of business types widely used in voice, data, audio, video, and images. In order to support various types of services, the next-generation mobile communication system is required to support higher data rates, higher spectral efficiency, and a complete QOS guarantee mechanism, and provide better mobility support and seamless network coverage. Realize the goal of providing communication services for users anytime and anywhere. [0003] The second generation of mobile communication uses time division multiple access (TDMA) technology (such as global system for mobile communication (GSM)) and narrowband code division multiple access technology as the main access technology. The third-generation mobile communication uses wideband code division m...
