HSDPA CONCEPTS (4)
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

the UE know the relative transmission power it is allowed to use for
data channel transmission
Spreading factor = 256

the relative transmission power the UE is allowed to use for data

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
