What’s new in 2021? Spectral Efficiency Improvement
QPSK Based Overlap Category
The spectral efficiency is simply the number of bits transmitted over a frequency
bandwidth in a specific time and is measured in bits/s/Hz.
Far
𝐷𝐿_𝑃𝑎𝑦𝑙𝑜𝑎𝑑 𝑏𝑖𝑡 /3600𝑠𝑒𝑐𝑜𝑛𝑑
𝐷𝐿 𝑆𝑝𝑒𝑐𝑡𝑟𝑢𝑚 𝐸𝑓𝑓𝑖𝑐𝑖𝑒𝑛𝑐𝑦 =
𝑈𝑠𝑒𝑑 𝑅𝑒𝑠𝑜𝑢𝑟𝑐𝑒 𝐵𝑙𝑜𝑐𝑘 𝐵𝑎𝑛𝑑𝑤𝑖𝑑𝑡ℎ (𝐻𝑧)
So any root causes that make Low DL Cell Throughput will direct impact to low SE :
1. Transport congestion will choke capability to get higher cell throughput even in
good radio condition with high MCS index
2. Bad radio condition, the most basic and common factor that controls the spectral
efficiency and throughput is the radio quality. If the quality network is bad, then
that puts a limit on the throughput gain that it can achieve. A higher quality will
result in a higher CQI value and consequently, a higher MCS index (more
efficient).

1. Near site overlap
2. Mid site overlap
3. Far site overlap
4. End cell overlap
• Based on location of Overlap can be divided to :
•
Nearby cell : CEU distributed nearer than average TA distribution
•
Far : CEU distributed after 1st tier site
•
Middle : CEU distributed within TA distribution but still in between 1st tier site

Average of DL Spectrum Efficiency (bits/s/Hz)

The spectral efficiency is simply the number of bits
transmitted over a frequency bandwidth in a specific time
and is measured in bits/s/Hz.

*)Troubleshooting procedure: Sleeping Cells
1. Check the status of the RNC cells
Run the DSP UCELL command in the RNC LMT and query the execution result. If the cell status is abnormal, it
indicates that the Sleeping Cell problem does not occur. If the cell status is normal, proceed to the next step.
2. Check whether the cell is barred
Run the LST UCELLACCESSSTRICT command in the RNC LMT and query the execution result. If the cell is barred, it
indicates that the Sleeping Cell problem does not occur. If the cell status is normal, proceed to the next step.
3. Check the cell radius
Run the LST LOCELL command in the RNC LMT and query the execution result. If the cell is extremely small, access
fails in the area beyond the cell radius, which is not a Sleeping Cell problem. If the cell status is normal, proceed to the
next step.
4. Check the alarm shield of the NodeB
Run the LST OBJALMSHLD: QRMD=OBJ command in the NodeB LMT. Check whether the execution result shields from
some important alarms. If the alarm shield is disabled and the alarm is reported, process the alarm emphatically. If
the execution result does not shield from any alarm, proceed to the next step.
5. Check the AAL2PATH configuration (the transmission mode is ATM)
Check whether the AAL2PATH configuration on the RNC is consistent with that on the NodeB. If not, the problem is
not a Sleeping Cell problem and thus you need to modify the AAL2PATH configuration to ensure the consistency
between them. If yes, proceed to the next step.
6. Check the status of the NodeB cells
Run the DSP LOCELL command in the NodeB LMT and query the execution result. If the cell status is abnormal, it
indicates that the Sleeping Cell problem does not occur. If the cell status is normal, proceed to the next step.
7. Check the VSWR
Run the DSP VSWR command in the NodeB LMT. Query the VSWR of the RRU. If
the VSWR is lower than 10
(illegal), it indicates that the RRU is faulty.

Background
 The most basic and common factor
that controls the spectral efficiency
and throughput is the SINR (Signal
to Noise and Interference Ratio). If
the SINR of a network is bad, then
that puts a limit on the throughput
gain that it can achieve. So, the first
thing to verify is the average SINR
of the network.
Start
Traffic
Analysis
The Another way is to enable load
balancing between the layers or
neighbor cells and ensuring that the
higher CQI layer gets more load. Load
balancing usually also comes in two
modes
 Idle Mode: In this case, the eNB
sends the frequency in the RRC
Release command to the UE. eNB
increases the priority of the target
frequency for that UE temporarily
and the UE tries to reselect to that
frequency in idle mode.
Cell Coverage
Throughput Calculation
It is better to use
antennas which assign a
different RET port
(electrical tilt) to LTE.
That provides flexibility
for optimization.
Subscribers Supported Per
Cell
Finding
 Connected Mode: In this case, the
eNB calculates the PRBs or user
count and tries to maintain target
load values by performing load
based handovers between the layers
or neighbor cells.
If sites are too close to each other, they will have a higher
tendency to interfere with each other and will require
aggressive down-tilts to limit overlapping. The distance is
something that is usually fixed as LTE sites mostly use the
previously deployed network. So, there is not much to do
at this level other than downtilts to improve SINR and
reduce overlapping.

The easiest way is to give a higher priority to the L1800 and that will shift most of the
UEs in L1800 coverage away from the L800. This will ensure better CQI and the
spectral efficiency for users and thus a better throughput. Another way would be to
keep them on the same priority and provide a frequency offset to move the users to
L1800. This is more reasonable if the L1800 is also getting overloaded then the amount
of load to be shifted can be tuned by varying the offsets.

13. Low Spectral Efficiency (< 1-1.25)
Root causes that make Low DL Cell
Throughput will direct impact to low SE :
• Transport congestion will choke
capability to get higher cell throughput
even in good radio condition with high
MCS index.
• Bad radio condition, the most basic and
common factor that controls the spectral
efficiency and throughput is the radio
quality. If the quality network is bad,
then that puts a limit on the throughput
gain that it can achieve. A higher quality
will result in a higher CQI value and
consequently, a higher MCS index (more
efficient).
