Problems solved by technology

[0017] The existing technology does not propose how to allocate subcarriers to users under the sector under the directional antenna mode. Therefore, for most existing multi-carrier systems based on sector deployment under the directional antenna, its practicability is limited. not suitable for expansion

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

[0071] Step 11. In the directional antenna mode of the multi-carrier system, divide the primary and secondary subcarriers through the network planning base station controller (RNC), and determine through network initialization.

[0072] When dividing the subcarriers of each sector, the following principles are followed:

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

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

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

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...
