How can I improve my DL throughput in LTE?

September 8, 2022 Chris Normand 0 Comments

One thing that can really help in increasing the throughput is the optimum mobility strategy. Consider two LTE layers, for instance L800 and L1800 with same bandwidth. In this case, L800 will have a higher coverage as it is a lower frequency. So, the user count on L800 will be higher compared to L1800.

What affects LTE throughput?

LTE throughput depends on the following parameters: Bandwidth. Channel quality. Network load.

What is the reason for low throughput in LTE?

b) If the maximum number of RRC connections active per cell is close or equal to the maximum number of RRC connections supported, then. The cause for low throughput is load.

How do I optimize my LTE network?

So to be able to increase the quality of 4G LTE network, it is necessary to optimize the coverage area of 4G LTE network in Sragen by using the physical tuning method, which is to adjust the antenna tilt, azimuth antenna, power. Key Performance Indicator is a reference to determine the performance of a network.

What is LTE throughput?

In LTE these is 25% of overhead for Controlling and signalling like Reference Signal, PSS,SSS and PBCH etc. So the effective throughput will be 300 Mbps. The 300 Mbps number is for downlink and not valid for uplink. In uplink we have only one transmit chain at UE end so no MIMO benefits.

How fast is 5G?

5G can be significantly faster than 4G, delivering up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates. 5G has more capacity than 4G. 5G is designed to support a 100x increase in traffic capacity and network efficiency.

How is TB LTE size calculated?

Step to Calculated TBS

The total number of REs within the bandwidth of a single RB is 12 x 14 = 168 using normal cyclic prefix. The final value is multiplied by the number of allocated Resource Blocks to generate a value for .

What is PB in LTE?

There are two parameters in LTE Pa and Pb which define the power of the Reference Signals against the other symbols e.g. PDSCH Symbols. I will just explain with an example. If the Pa is -3 and Pb is 1, then that means that the Reference Signals will be having 3 dB higher power than the PDSCH symbols.

What is BLER in 5g?

Block Error Rate (BLER) is defined as the number of erroneous received code blocks/total number of received code blocks. The code block is considered to be error-free if its attached CRC code matches the one calculated by the receiver.

How does mobile communication manage latency?

Minimizing latency by reusing keepalive connections, geo-positioning servers and data closer to the client, optimizing TLS deployments, and all the other optimizations we outlined earlier are even more important on mobile networks, where roundtrip latencies are high and bandwidth is always at a premium.

What is PA in LTE?

The 3GPP has defined two parameters PA and PB that control downlink power allocation. PA represents the power of the reference signal when compared with OFDM symbol A and PB represents the power of the reference elements of OFDM symbol B as compared with OFDM symbol A.

How fast will 6G be?

6G is expected to provide substantially higher throughput and data flow. As envisioned, 6G will enable the following: deliver a theoretical data rate of about 11 Gbps simultaneously across multiple gigahertz channels; deploy up to three 160-megahertz (MHz) bandwidth channels; and.

Why is 5G so slow?

So, why are some 5G connections so slow? The first, and most impactful, reason is that the far-reaching 5G signals that have powered the vast majority of carrier rollouts in the US – especially from AT&T and, to a lesser extent, T-Mobile – have used low-band carrier frequencies.

What is code block in 5G?

In 5G NR, the transport block consists of up to million bits and the code block consists of up to 8448 bits. Due to the difference in the size of the transport block and the code block, the scheme of the CRC processing suitable for the transport block and that suitable for the code block are different.

What is code rate in LTE?

Code Rate. Simply put, the code rate can be defined as the ratio of the data rate that is allocated for a subframe and the maximum data rate that ideally can be allocated in the subframe.

What is TTI in LTE?

TTI bundling: The Transmission Time Interval (TTI) is the time unit for the eNodeB to schedule UL and DL data transmissions.

What is MCS in LTE?

MCS (Modulation and Coding Scheme) defines how many useful bits can be transmitted per Resource Element (RE). MCS depends on radio link quality. The better quality the higher MCS and the more useful data can be transmitted.

What is rBLER in LTE?

rBLER: Residual Block Error Rate. The ratio of data blocks with transmission errors after initial transmissions and retransmissions to all initial transmission data blocks.

What causes internet lag?

Lag is another term for delay, and it is caused by high latency. Poor server processing power, low bandwidth or packet loss can cause lag, too.

How do you measure internet latency?

A simple test to measure latency is to run a ping. This is a network diagnostic tool primarily used to test connectivity between two servers or devices. To ping a destination server, an Internet Control Message Protocol (ICMP) echo request packet is sent to that server.

What is crsGain?

“Sets the DL power of the Cell specific Reference Signal (CRS) relatively a reference level defined by the power of the PDSCH type A resource elements. If crsGain is +3dB, the CRS power is 3dB higher than that of a PDSCH type A resource element.
