1 Overview1.1 About This Document

This manual describes the functions, operation procedures, detailed parameter settings,

problems, and subsequent version plan of the WiMAX APUS V1.0 Beta. It does not involve

the specific algorithms of the tool. It is intended for APUS users to understand its operations,usage, parameter settings, and existing problems.

1.2 Platform FunctionsThe WiMAX APUS tool V1.0 Beta is intended for the WiMAX network and integrated with

the relatively independent functions of automatically planning the WiMAX frequencies,preambles, and neighboring cells. The WiMAX APUS V1.0 Beta does not provide the multi-

carrier planning function because the multi-carrier planning scheme requirements are to beclarified. The automatic frequency, preamble, and neighboring cell planning functions of the

tool are described as follows:

1. Frequency Planning

The frequency planning is performed by the Frequency Plan module. After engineering

parameters are imported, the frequency planning schemes in the multi-frequency, single-

frequency FFR, multi-frequency FFR, and FDD pre-planning scenarios. The multi-

carrier scenario is not supported temporarily. Only the frequency planning results aredisplayed. In the case of FFR network, frequency planning and segment planning results

are displayed, and a maximum of 18 frequency channels and six sectors are supported.The planning results can be directly exported to an EXCEL or KML file.

2. Preamble Planning

The preamble planning is performed by the Preamble Plan module. After engineeringparameters are imported, the Preamble, ULPermbase, DLPermbase, and CDMAStart

planning can be implemented in the single-frequency FFR, multi-frequency FFR, and

multi-frequency PUSC with all SC networks. The preamble planning involves the

segment and IDCELL influences. The preamble reuse planning also involvesminimization of the segment and IDCELL interference. The planning results can be

directly exported to an EXCEL or KML file.

3. Neighboring Cell Planning

The neighboring cell planning is performed by the Neighbour Plan module. After

engineering parameters are imported, the automatic planning of WiMAX neighbor cellscan be implemented. With the forced preventive measure in the neighboring cell

planning, the two cells with the same frequency and preamble cannot be neighboring

cells of the same cell.

2 Program Running2.1 Main Interface of the Program

The following figure shows the main interface of the WiMAX APUS.

Figure 1.1 Main interface of the WiMAX APUS

The running interface of the prototype tool consists of three parts: menu and shortcut icon bar,data display area, and status bar. The menu and shortcut icon bar provides function options.

You can specify the frequency, preamble, and neighboring cell planning functions here. The

data display area displays the data to be planned and the imported engineering parameters.The status bar displays the current planning status.

2.2 Input Engineering Parameters

The program can perform automatic planning only after the required engineering parametersare imported properly. The tool uses the unified engineering parameter table (see the

attachment). The engineering parameter table contains the following parameters:

1. BSID: ID of the carrier. This parameter is mandatory for neighboring cell planning.

2. SiteName: Name of the BS. This parameter is mandatory for automatic planning. The

values must be different for different BSs.

3. SectorName: Name of the cell. This parameter is mandatory for automatic planning. The

values must be different for different cells.

4. CarrierID: ID of the carrier in the multi-carrier network. This parameter is reserved for

the multi-carrier network scheme. It can be left blank.

5. Azimuth(): Azimuth of a cell. This parameter is mandatory for automatic planning. Itindicates the included angle to the north.

6. BeamWidth: Beam width of the antenna. This parameter is mandatory for automaticplanning. It indicates the half-power beam width, usually 65 on the live network.

automatic planning.

11. NeedToPlan: Whether to plan the carrier. YES: to plan the carrier; NO: not to change the

existing settings. This parameter is mandatory for automatic planning.

3 Automatic Planning3.1 Frequency Planning Procedure

Step 1 Click the frequency planning button or choose Tools > Frequency Plan. The followingwindow is displayed.

Step 2 Click the import button to import the engineering parameters required for planning. Duringimport, ensure that the engineering parameter table complies with specifications and contains

all the required information (for details, see section 2.2"Input Engineering Parameters"). Afterthe engineering parameters are imported, the frequency planning button is available, as shown

in the following figure.

Step 3 Click the frequency planning button. The Set Parameter dialog box is displayed, as shown inthe following figure.

The following describes how to set the parameters by examples:

Three continuous frequency channels are available. To implement FFR network, enter3 in

Total Frequency Numbers, and then select FFR.

Six discontinuous frequency channels (FDD frequency resources) are available. To implement

PUSC with all SC network, enter6 in Total Frequency Numbers, and then select FDD and

PUSC with all SC.

Use the planning of the FFR with three frequency channels as an example. After the planning

is completed, the optimization button is available. The following figure shows the planning

results.

WiMAX V32C03


Remarks: This version does not support multi-carrier planning. With regard to pre-planning of

FDD frequency spectrum resources, if multiple carriers and the FDD planning mode areselected, available frequency channels are evenly distributed on both sides of the FDD

frequency spectrum. Frequency planning ensures that the same BS uses the frequency

channels evenly. The current version adds the frequency bandwidth option because multiplecarriers of the same sector are in the same filter.

Step 4 Click the Export button. The Export File window is displayed, as shown in the followingfigure.

You can select the EXCEL or KML file to export data.

Step 5 (Optional): If the frequency planning results are unsatisfying, you can perform optimization.Click the Optimize button. A dialog box is displayed, as shown in the following figure. (It is

4 Existing Problems and VersionPlan

4.1 Frequency Planning Accuracy ProblemsFrequency planning consists of two steps: 1. Build a model for inter-cell potential

interferences; 2. Plan frequency channels on the existing mapping model to minimize the

interferences on the entire network. The existing frequency planning schemes still have the

following problems:

The interference matrix model is built by using engineering parameters based on the relative

topology relation. It is hard to guarantee the accuracy.

The optimization procedure depends mainly on random searches. The automatic planningoptimization speed is low in the large-scale networking mode.

It is planned to use the live network data as the basis of interference matrix establishment for

network optimization in later versions.

4.2 Automatic Planning Problem for Multi-Carrier Network

The WiMAX multi-carrier network policies still have many uncertainties. Therefore, multi-

carrier planning is temporarily unavailable and planned to be provided in the next version.

4.3 Querying the Version Number
