DL mimomode of SRB1 change impact on accessibility

LTE2026: RRC Signaling Robustness -feature provides an increase in the reliability of the downlink radio resource control (RRC) signaling messages on the physical downlink shared channel (PDSCH) and the physical downlink control channel (PDCCH) to reduce the latency for the RRC procedures and to improve call setup and handover (HO) success rates.


dlSrbMimoMode :- This parameter determines the MIMO mode to be used for Downlink SRB traffic 

1: TxDiv 

2: SpatialMultiplexing


Suggestion:- purpose of changes that SRB1 do not required capacity so we can use dlmimomode tx diversity instead of special multiplexing so that dl can be more reliable and that can give benefit in success rate

I did changes for worst cells in my network from special multiplexing to TX diversity and good improvement seen

Downlink signals are  made up of many different components. For example, Reference Signal, PDCCH, PDSCH etc. The RS power and the SCH powers are key RF optimization parameters that influences the cell coverage. It is set according to the cell size. The higher the setting, the larger the cell coverage  on the downlink, but leaves smaller power headroom available for other downlink signals  and channels. The relation between RS power and power on PDSCH symbols (includes type A and type B symbols), has to be defined and reported to the UE, in order for the UE to demodulate 16QAM and 64QAM.1 PDSCH type A symbols has only PDSCH RE’s, PDSCH type B symbols has mixed RS and PDSCH REs. Parameter PA sets the power of PDSCH type A RE relative to cell‐specific RS, PB sets the power relation between PDSCH type B RE, and PDSCH type A RE (ρB/ρA in 3GPP). The ratio of PDSCH EPRE to cell‐specific RS EPRE among PDSCH REs for each OFDM  symbol is denoted by either ρA or ρB a...

LTE Layer management Strategy and basic working [LMS] Unlock

LMS Insight Layer Management Parameter Optimization is important aspect & it is triggered when all possible optimization techniques for ensuring best experience to customers is exhausted in the current layer For Example in a typical 3 Layered cellular network, we have LTE layer (with a mix of TDD(2.5GHz) and FDD(1.8GHz)), followed by WDCMA Layer (WCDMA2100) & then the GSM layer (1800 MHz Before actually working on Layer Management Parameter Optimization, we need to ensure Traffic Balancing within the layers is proper & as per recommendations to give desired customer experience Pre-requisite Actions Ensure below checks before moving to optimize the Layer Management Thresholds for a cell. Traffic balancing within layers should be optimal -  if network has 2 layers of LTE i.e. both TDD-20 MHz & FDD-5 MHz, Traffic distribution for collocated cells with TDD/FDD should be 75:25 (TDD: FDD) or better. This is applicable to networks with 2 carriers of WCDMA as well where the...
