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).

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.

Overlap 2 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. Cell Number (Initialized by Coverage Dimensioning) Total Subscribers Satisfy Capacity Requirement No Adjust Cell Number Yes Cell Number End 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.

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).
