The UE report the CQI to support the various transmission modes open to them. The UE reports their feedback to the eNodeB periodically on PUCCH or no-periodically on PUSCH. The CQI feedback can be wideband referring to the entire spectrum, or sub-band CQI value applies to each sub-band in a frequency selective mode, PMI can be wideband or sub-band Rank Indicator influences the number of CQI rep...

LTE PDCCH Symbol Adaptation - Huawei Settings
มุมมอง 9132 ปีที่แล้ว
LTE Optimization LTE PDCCH Symbol Adaptation Huawei Settings PDCCH symbol adaptation enables the eNodeB to adjust the number of symbols occupied by a PDCCH based on the number of required CCEs. When a PDCCH requires fewer CCEs, the eNodeB decreases the number of symbols occupied by the PDCCH and allocates idle time-frequency resources to PDSCH. When a PDCCH requires more CCEs, the eNodeB increa...
LTE MCS Optimization for UEs in Handover Huawei Parameters

LTE MCS Optimization for UEs in Handover Huawei Parameters The principle: when A UE experiences relatively poor channel quality during and immediately after a handover. To ensure a stable data transmissions in this situation. the eNodeB uses different MCS selection policies before, and after the timer specified by the Handover Static MCS timer parameter. The eNodeB Starts the timer when the UE ...
Optimization of LTE Msg 2 Random Access Response for initial access and handover - Huawei Parameters

Optimization of Message 2 Random Access response - Huawei Parameters The UE initiate a Random Access Procedure by sending a RACH preamble to eNodeB. If the preamble is correctly received, the eNodeB acknowledges it by sending a random access response message, Message 2. The message sent over the physical downlink control channel PDCCH, is actually a pointer via RA-RNTI to the actual resource in...
LTE CQI Adjustment Value and steps - Huawei Setting

LTE CQI Adjustment value and steps - Huawei Setting LTE Throughput RF optimization Course An eNodeB calculates a CQI adjustment value for a UE based on HARQ feedback. and sets an initial value for the UE during initial access, RRC connection reestablishment, or incoming handovers. The larger the CQI adjustment value, the more aggressive the MCS for the UE. The smaller the CQI adjustment value, ...

LTE CQI Reporting period - Huawei setting (LTE Throughput RF optimization Course) CQIs can be reported periodically or aperiodically. For a UE in frequency selective scheduling (FSS) mode, the eNodeB selects aperiodic CQI reporting, and the reporting modes are specified in uplink scheduling and CQIs are reported over the PUSCH. For a UE in frequency diversity scheduling (FDS) mode, the eNodeB s...

Hi, In case L.E-RAB.AbnormRel.Radio.Other, What are its causes and how can they be optimized?
Very Very Crucial Information.
Very well explained about Ncs and cell radius..
Hi, how we will define DL/UL imbalance?
At time 9:17, the example of Rho_B/Rho_A = 1.25 --> The Power of PDSCH_B in this cause should be = -2.03 dB + 18.22 right? (in TH-cam is -2.03+15.22). By the way, thank you very much for the great explanation.
Hi, Thankyou very nicely explaned. Could you please give the spec ref for Prs=Psingle_port - 10*Log(12*Nrb) + Log(1+Pb).
Meassage-2 provides Temporary C-RNTI and Meassage 4 provides C-RNTI. Would you please check this and update
Thank you! Can you explain please why you add 10*log10(1+Pb) to Reference Power formula? is it just P_RS = P_singlePort -10*log10(12*Nrb)?
ChatGPT is better than you
Please explain, why Ppdsch_B= 20.88mW? In the scenario when Pb=0, Pa=-3. If Pa = -3, as in first example (Pb= 1, Pa= -3) RS Power is 18.2 (66.67mWatt) not 15.2. it means Ppdsch_B should be 0.6264*66.67=41.47 mW. Right?
Hi, The RS power formula include the value of Pb: Prs=Psingle_port - 10*Log(12*Nrb) + Log(1+Pb). in the second example Pb=0 not 1, so the value of the RS power is 15.2 for Pb=0 and 18.2 for Pb=1. Kind Regards, Smart Telecom Education
Very Deep and interesting,
Great Explain, Could you pls start series on CA
Thanks a lot for this very clear Course

Thanks
can you please share link of that slides?

I think the enodeB will release the ERab only when TrelocationOverall timer expires. If the UE reconnects back from Idle befor tTrelocOverall expires, it will reconnect with a fresh UE context, then MME would release the old context on the source eNb due to the duplicated UE context.
Awesome 👍
thanks
OMG, thank you so much😳
