Cellular-Planning and Optimization

Factors Affecting Throughput in LTE :-

noreply@blogger.com (Unknown) — Sat, 27 May 2023 01:01:00 +0000

Factors Affecting Throughput in LTE :-

Low mcs, Low sinr, Low rsrq , high prb usage, wrong earfcn Definition, no Carrier aggregation ör missing ca configuration, Pci , Route sequence index collision, Wrong tac planning, gateway security problem, etc.

air quality (now sinr, rsrq, etc etc), modulation level. For example, 16QAM, 64QAM, etc.

Low Throughput Issue:-

1 - Poor coverage (BLER)

2 - Availability issue

3 - Uplink Interference

4 - A poor RACH decoding SR

5 - High error on S1 link.

6 - Delay on S1 link towards MME & SGW.

7 - Accessibility issue.

8 - Handover failure.

9 - Lack of PRBs.

10 - Problematic UE.

11 - Downlink Interference (Bad CQI)

12 - MIMO Parameters

13 - High VSWR

14 - High radio errors or instability issue.

15 - Maximum number of RRC connections active per cell

16 - Maximum number of users per TTI supported per cell.

17 - Core network, MME/SGW, etc

18 - Transmission instability & bottleneck.

19 - Incorrect parameter setting.

20 - Badly tuned handover parameters.

21 - High traffic on Cell limit THp

Radio Analysis - Downlink

22 - CQI (Channel Quality Index) and RI (Rank Indicator) reported from UE.

23 - Transmission Mode: MIMO (tm3) vs. TxD (tm2) vs. SIMO (tm1)

24 - MCS vs. number of assigned PRBs vs. assignable bits in scheduler

25 - UE Scheduling percentage of TTIs (how often is the UE scheduled)

26 - CFI (number of OFDM symbols for PDCCH) vs. MCS vs. % scheduling

27 - HARQ

28 - RLC retransmissions

29 - Another cause of low (or lower than expected) throughput is that the UE is not being scheduled in every TTI. Packet loss can lead to (retransmissions, dropped in RBS, etc)

Radio Analysis – Uplink

30 - Uplink scheduling overview

31 - BSR (Buffer Status Report)

32 - PHR (Power Headroom Report) – is the UE at maximum power?

33 - Cell bandwidth vs. maximum allowable PRBs

34 - Link Adaptation

35 - MCS available and 16QAM

36 - PDCCH SIB scheduling colliding with UL grant

37 - HARQ (less important, because we can measure SINR)

38 - QPSK cases in UL has increased from ~30% to ~40%. If more QPSK cases then there are more UEs in poor radio conditions

Bad RSRP and RSRQ -

Issue reasons and solutions please

If Rsrp and Rsrq together goes to bad, it means there is weak coverage or weak signalization. Need to check antenna position and which site/cells should serving to there , mostly it is causes by weak coverage… Secondary issue is possible to there is handover problem among cells due to very aggresive handover parameter settings… So handover requests goes to late.

Look at parameter settings.
