1 Introduction 1.1

Scope This document describes how to commission Flexi Multiradio/AirScale BTS LTE sites using the Commissioning wizard in the BTS Site Manager software. This document provides instructions on how to proceed with template commissioning when a commissioning file is available. NOTICE: Only properly trained and authorized personnel may perform installation, commissioning, or maintenance operations on any Nokia base transceiver station (BTS).

1.2

Requirements

1. Verify that the correct LTE Flexi BTS Site Manager is installed in PC. 2. Verify that all available data and work orders are available: •

HW work order named “Configuration xxxx.pdf

•

Transmission WO EIPCIxxx.xls”

•

Radio work order Rxxx.doc

•

Antenna files

3. Verify that you have all the needed documentation by installing NED libraries in PC 4. Verify that site is installed and that contact details for all people involved are known. Site Installer, RNC Engineer and Transmission Engineer have to be contacted.

2 Performing template commissioning 2.1

Purpose Template commissioning provides the option to commission an eNodeB using a given site commissioning file. This will significantly reduce the number of parameters that need to be configured as mainly only some site specific parameters need to be changed. All parameters needed to configure the BTS site are determined at the network planning stage. It is essential that the input values match the expected values in the network plan. Steps 1. Choose the View  Commissioning menu item or click the Commissioning button on the View Bar. The Commissioning – Introduction page opens.

Commissioning - Introduction page with Template option selected 2. Select the commissioning target by clicking the option BTS site.

3. Select the Template option.

4. Select a commissioning file. You can browse for the commissioning file by selecting the Browse option. The supported file formats are XML and ZIP (including the XML format commissioning files). When you selected the BTS site option, select the appropriate ZIP file containing both the BTS and TRS commissioning files.

5. Click the Next button.

2.21 Defining concurrent mode settings In the Commissioning - Concurrent Mode Settings page you can set concurrent mode setting for Multiradio BTS (Airscale does not support this feature in FL16A). This page is shown when the HW configuration includes at least one radio module supporting concurrent technology 2G in LTE-2G sharing. The page is not shown in chained RF configurations because RF sharing is not supported in chained RF configurations. Note also that the page is not shown when HW configuration includes FSMD/E and radio module supporting 2G from RF interface 4 but does not include radio modules supporting 2G from other RF interfaces. Also the page is not shown when HW configuration includes FSMF and radio module supporting 2G from RF interface 6 but does not include radio modules supporting 2G from other RF interfaces.

Example without RF sharing:

Example with RF sharing:

NOKIA Hellas 7


2.22 Defining cell resources In the Commissioning - Cell Resources page, you can create local cells, and define antennas of the Radio Modules and carrier power to the local cells. Local Cell Resource (LCR) is a concept for defining all the hardware that a global cell requires in the base station. Local cells (LCELL) are then mapped to global cells (LNCEL) on the commissioning RNW page. The information is available within the HW Work order and the RR Data as it is presented below.

In case of 2x2 MIMO, use Dynamic Open Loop Mimo.

NOKIA Hellas 8


NOKIA Hellas 9


2.23 Defining LTE carriers In the Commissioning - LTE Carriers page, the LTE carrier frequencies are defined for local cells; those are assigned then automatically to global cells (LNCEL) and shown as read-only information on the commissioning Radio Network Configuration page. The allowed E-UTRAN Absolute Radio Frequency Channel Number (EARFCN) values for frequency bands are displayed below the Carrier candidate table. LTE carrier candidates are determined at the network planning stage. It is essential that the value input matches the expected value in the radio network plan. You should not select the values arbitrarily. The Equipment view displays the selected local cell and the Radio Module assigned to it as highlighted.

3. Repeat the procedure for each antenna. 4. Click the Next button.

2.26 RET Setting (1/2) In case, that there are RET units, use the following menu to configure it. RET Commissioning is described in 2.32 and 2.33 since the BTS commissioning should be completed before the RET units be detected and configured.

NOKIA Hellas 3


2.27 RET Setting (2/2)

1)

Set the mechanical and electrical tilt according to the BTS configuration Work Order.

2)

Make sure you use the correct RET configuration file. This should be provided by CosmOTE in case of a new antenna type introduction.

2.28 System Module External Fault and Control Settings Since LTE is not used for External Alarms, leave the following page as it is.

2.30 Sending parameters to BTS site On the Commissioning - Send Parameters page send the previously entered commissioning parameters to the BTS site. You can also view the commissioning parameters and save them in an XML file.

Commissioning - Send Parameters page Wait for the site to reset and auto detect all connected antenna line devices. Then start commissioning wizard again and proceed with MHA commissioning choosing “Reconfiguration Commissioning”. Go to Antenna Line Management page and keep selected 3GPP/AISG communication and DC voltage only for the branches where MHAs and RETs have been detected:

Commissioning – Antenna Line Management page

2.31 Defining AISG MHA setting In the Commissioning - AISG MHA Settings page define AISG MHA settings for auto-detected AISG MHAs according to the work orders:

NOKIA Hellas 6


Commissioning – AISG MHA Settings page

Steps 1. Select for every auto-detected MHA the usage and the connected Antenna “This BTS” is used for own MHAs and will be also used until further notice also in case of RF shared antenna port and MHA. For MHAs referring also to LTE BTS select the correct Antenna line, that is connected to. When the option “Other BTS” is used, this antenna option is grey. The “Other BTS” option is not applicable for CosmOTE network and should never be used. 2. Repeat the procedure for every auto-detected MHA.

affects only another technology (2G or 3G). Set the antenna port only for the antenna port that detects the RET. The value is purely informative but should nevertheless be set correctly. 3. Additional data Set the correct antenna type, azimuth and other info in the relevant fields. Make sure you name the RET according to the valid Cosmote work order instructions.

This feature introduces 4-branch diversity reception per sector, with maximum ratio baseband combining of four uplink signals. Benefits The LTE72: 4-way RX diversity is transparent to used antenna structures. It can be used with one physical 4 port antenna or two cross polarized antennas. This feature provides the following benefits: • reduced site number for building the coverage. • high UL data throughput • less BTS sites for coverage Interdependencies between features

The following features can not be enabled in combination with this feature: • LTE48: Support of High Speed Users • LTE447: SW support for RF sharing GSM-LTE • RAN2126/LTE435: RF Sharing WCDMA-LTE Activating LTE72: 4-way diversity using BTS Site Manager Feature is activated by proper configuration of Cell resources settings. 4 receiving antennas are configured to one cell or all cells of the eNB by defining 4Rx antennas in the LCEL resourceList.
