LTE Paging Mechanism
Since I got a lot of requests to explain the LTE paging mechanism and paging capacity, so I decided to write a couple of short articles on these topics. Paging is a mechanism to initiate services for UEs that are Read More
LTE Throughput Optimization: Part 2 – Spectral Efficiency
I explained the gains of optimizing the PDCCH (control part) of the LTE subframe in my previous article. Let’s have a look at the data part (PDSCH) and find out various ways to improve it’s efficiency. The spectral efficiency is Read More
KPI Optimization: LTE Call Drop Rate
One of the most important KPI is the LTE Call Drop Rate. Every network is striving to improve this KPI and it has become more important in LTE since the introduction of VoLTE. In simple words, a call drop in Read More
LTE Throughput Optimization: Part 1 – PDCCH Capacity Enhancement
There are many ways to optimize LTE throughput and I will try to cover all of them. The LTE throughput optimization procedure described in this article requires PDCCH enhancements. The general idea is that the LTE subframe is made up Read More
KPI Optimization: LTE ERAB Success Rate
The second major KPI for LTE is the LTE ERAB Success Rate which is also part of the accessibility. After the UE has completed the RRC Connection which has been explained in my previous article, LTE KPI Optimization: RRC Success Read More
LTE KPI Optimization Deep Dive: RRC Success Rate
This is the first part in LTE KPI Optimization and more related articles will be published soon. So, let us get started without wasting any further time. LTE KPI Optimization – RRC Success Rate In LTE KPI Optimization series, this Read More
PCI Planning: Facts & Myths
Physical Cell ID Planning PCI planning is one of the most important things to understand while planning an LTE network and it is usually left untouched in most of the LTE manuals and text-books. As already explained, the PCI is Read More
LTE Frame Structure Made Simple
A typical LTE frame is 10 ms (milliseconds) long. Each LTE frame has 10 sub-frames (1 ms each) while each sub-frame is further divided into 2 slots (0.5 ms each). The slots are divided into symbols – each slot has Read More
LTE Network Entry Steps
In order to understand LTE network entry steps, we must have knowledge of physical channels which you can get from my article “LTE Frame Structure Made Simple“. The first thing UE needs to do is to search for Primary Synchronization Read More
