Rise-over-Thermal Noise
In order to decode received data correctly, the uplink
interference shall be controlled.
Rise-over-Thermal is a measure of the uplink load.
NodeB monitors uplink interference and tells UE
how much power can be used to transmit uplink data.

Scheduling During HSUPA operation NodeB scheduler considers the
trade-off between the following two points:
Several users those want to transmit at high data rate all the
time
Satisfying all requested grants while preventing overloading
and maximizing resource utilization

HSUPA Key Technologies Higher Data
Rate For a 10ms TTI UE, peak data rate is limited to 2 Mbps.
For a 2ms TTI UE, the theoretical maximum data rate is 5.76Mbps.
The conditions to get 5.76 Mbps
Lower channel coding gain
Effective code rate = 1
Requires very good channel conditions to decode
Lower spreading factor
UE uses SF 2
Multi-code transmission
UE uses 4 codes, 2 with SF2 and 2 with SF4
Calculation of 5.76 Mbps: 2 (3840000 / 2) + 2 (3840000 / 4) = 5.76Mbps

HSUPA Channel Operation
The UE sends a transmission request tothe NodeB for getting resources.
The NodeB responds to the UE with a
grant assignment, allocating uplink band
to the UE.
The UE uses the grant to select the
appropriate transport format for the Data
transmission to the NodeB.
The NodeB attempts to decode the
received data and send ACK/NACK to
the UE. In case of NACK, data may be
retransmitted.

E-DCH Active Set and Mobility Support
There are three different types ofradio links in the UE E-DCH active
set:
Serving E-DCH Cell: The cell from
which UE receives AGCH.
Serving E-DCH RLS: Set of cells that
contain at least the serving cell and
from which the UE can receive
RGCH
No-Serving RL: Cell that belongs to
the E-DCH active set but not belong
to the serving RLS and from which
the UE can receive a RGCH.

New Channels in HSUPA Operation
1. The UE sends a request for resources. The
request includes status of its data buffers and
is sent on E-DPDCH.
2. Based on the request from the UE, the
Node B allocates a resource grant to the UE.
The grant is sent on the E-AGCH channel. 3. This grant can be modified by the Node B
every TTI using the E-RGCH channel.
4. The UE transmits data on E-DPDCH.
Control information needed to decode the
data is sent on E-DPCCH.
5. The Node B decodes the received packet
and informs the UE whether it could decode
the data successfully or not on the E-HICH
channel.
