    FAST SCHEDULING AT NODE B

    The scheduler chooses the data that will be transmitted in the next TTI

    It sorts the users to be served

    Different scheduling techniques

    Max CQI: resource is allocated to the UE with the best radio

    propagation conditions Round Robin: every user is served in a sequential way

    Proportional fair: resource is allocated to the UE with the highest

    instantaneous relative channel quality

    NO SOFT HANDOVER ON DL

    The mobile has only one link from its best-server1.UM

    CELL POWER

    The cell power is shared between R99 and HSDPA users

    Two strategies possible for the HSDPA power allocation:

    Static allocation the HSDPA power is a fixed part of the cellpower

    Dynamic allocation the HSDPA power is the remaining cellpower after serving R99 users

    HSUPA CONCEPTS (4)

    HSUPA DOES NOT SUPPORT FAST LINK ADAPTATION

    Higher modulation order schemes are not supported

    FAST SCHEDULING AT NODE B

    The shared resource on UL is the UL noise rise i.e, the total power receivedby the Node B receiver

    The scheduler tasks are:

    To equally share this resource between users and to maintain the

    interference level experienced close to the maximum

    To select the transport format (nb of bits to be transmitted in a TTI) for

    the E-DCH transport channel with respect to:

    The maximum terminal power allowed

    The UE (User Equipment) category

    SOFT HANDOVER IS SUPPORTED

    PURPOSE

    Simulate network regulation mechanisms for a user distribution

    Uplink and downlink power control on R99 bearers

    Fast link adaptation in order to select HSDPA bearers

    Noise rise scheduling in order to select HSUPA bearers

    Obtaining network parameters

    Mobile: active set, required power, etc

    Cell: total DL power, UL load, etc

    THREE STEPS

    1. Obtaining a realistic user distribution

    2. Modelling network power control, fast link adaptation and noise risescheduling
