    Uploaded by

    Adil Murad
    The document proposes optimization activities for the second quarter to improve LTE and UMTS performance in the south region. For LTE, it suggests throughput improvement parameters, uplink power control optimization, and video experience optimization. For UMTS, it recommends CQI adjustment based on dynamic BLER and HSDPA inter-cell power sharing. Trial results are provided showing improvements in throughput, battery usage, and video streaming performance.

    LTE –PERFORMANCE UPLIFT
    1. Data User Experience Optimization -DL
    — A set of 10+ Performance Parameters were selected, studied &
    most optimal configurations were implemented.
    — These parameters impacted initial BLER, MCS, 64
    QAM ratio, CCE utilization reduction &
    throughput positively.
    — After trialing, these settings & positive results

    — With 2.6% increase in data volume, still we


    achieved:
    — 2.5% - 3% improvement in Day level throughput.
    — 4.36% improvement in BI throughput.
    2. Battery saving Optimization / UL Throughput
    — A trial was conducted on one cell to improve the UL Throughput/battery performance.
    — UL shared channel (PZeroNominalPUSCH) power was tuned from -67 to -96 dB.
    * % Improvement In
    Scenario RSRP (dBm) SINR (dB) * UL Throughput (kbps) Throughput

    OTT apps in background 23% 13%

    * This trial was done on a single cell & needs to


    be trialed on a larger area to understand the
    actual impact specially regarding throughput
    3. Video Experience Optimization
    — This feature allows us to enhance the video user
    experience. It helps with the below indicators:
    — Initial buffer time is reduced.
    — Reproduction start delay is reduced.
    — No streaming interruption.
    — These settings were trialed in DHA, results were
    very encouraging & in discussion with HQ.

    UMTS –PERFORMANCE UPLIFT
    CQI Adjustment by Dynamic BLER
    — This feature was trialed which gave
    an improvement of ~4% in HSDPA Throughput.

    — Mobile devices report the quality of the


    downlink channel via channel quality indicator
    (CQI) reports to the mobile network. Using these
    reports, the system continuously optimizes
    performance (at 10% BLER) by choosing the
    best transmission speed for the next TTI.
    — CQI adjustment feature looks at the number of
    ACKS/NACKS in previous transmissions to an
    end user and adjusts the reported values to
    correspond with the actual quality of the
    downlink channel. CQI adjustment stabilizes
    BLER for the HSDPA channel.
    HSDPA Inter-Cell Power Sharing

    — This feature is implemented on the NodeB.


    — When multiple HSDPA cells use the same PA, this feature enables
    one or more HSDPA cells to dynamically share the idle power
    resources of other HSDPA cells. This feature supports the power
    sharing among 4 HSDPA cells at most.
    — The following figure assumes that there are only two cells in a
    power sharing group: cells A and B. If cell A has data transmission
    requirements but its power resources are insufficient and cell B
    has available power resources, cell B shares its idle power
    resources with cell A. After data transmission in cell A is complete,
    cell B reclaims these power resources.
