ü  List of detected preambles
•        The eNB shall report a list of detected PRACH preambles to higher layers. Higher layer utilize this info for the RACH procedure
ü  Transport BLER
•        The ACK/ NACKs for each transmission of the HARQ process are reported to the MAC. Based on these ACK/NACKs the higher layers compute the BLER for RRM issues.

• What is 4g Network and evolution of 4g

If you are a greenfield or emerging operator aiming at building a competitive Broadband Wireless Access Network (such as, for example, WiMAX and LTE), you should not make the mistake of underestimating the effort you need to put in place. This is and will remain a complex undertaking, especially if your network has to stand out as a true carrier-class infrastructure delivering superior services while achieving business efficiencies.

2.     Inter-Frequency Handover Procedure

3.     Signaling Procedures for Inter-Frequency Handover

Characters of Inter-Frequency Handover:-

·       The carrier frequency of the current cell and target cell are different

·       Based on the triggering causes of handover

Inter-frequency handover can be categorized into four types:-

ü  Coverage-based

ü  QoS-based

ü  Load-based

ü  Speed-based

Why mobile system need handov

• LINK:-why handover is needed?

1.The mobility of UE

2.Load Balance

Handover is a basic function of a cellular mobile network. The purpose of handover is to ensure that a UE in CELL_DCH state is served continuously when it moves.

3G & 4G Coverage Real-Time Drive-Test & Optimization Case Study

3G Drive Test Case Study:-

Here we are highlighting few cases, which normally occur while doing the DT. It will give the idea to DT engineer regarding to the issues on the site while doing the DT.  There are many other issues which normally occur, and which we have to justify, but all such cases depends upon case by case, for example, Speech Codec issues, SQI issues, UL/OL issues.

If any other issues comes, which are other than those which are discuss below, please kindly let me know so I can provide you the reason to justify them.
