Physical Layer Information Exchange Process of HSUPA
The UE sends an SI request carrying buffer state,
UPH, and other relevant information through the E-
DPDCH.
The NodeB allocates resources through the E-
AGCH to the UE (AG procedure) or indicates power
adjustment through the E-RGCH (RG procedure).
The UE sends MAC-e PDU (service or signalingdata) through the E-DPDCH, and sends the control
information (required for demodulating the PDU)
and happy bit (indicating whether the UE is happy
with the current scheduled rate) through the E-
DPCCH.
The NodeB tells the UE whether the PDU has been
successfully demodulated through the E-HICH.

Grant Mechanism
Absolute Grant (AG)
Borne by the E-AGCH of the E-DCH serving cell.
Grant mode: An index (totally 31 index values) is used to indicate the Traffic-to-
Pilot ratio (E-DPDCH/DPCCH).
Significance of the Grant value: Maximum power ratio (E-DPDCH/DPCCH)
available for the UE.
Relative Grant (RG)
RG carries a command instructing the UE to increase, keep, or decrease its
current transmit power.
The Serving RG is sent by all the cells in the E-DCH serving RLs.
The Non-serving RG is sent by the E-RGCH in the E-DCH non-serving RLs.

E-AGCH Frame Format
The E-AGCH is a downlink common channel.
Fixed rate: 30 kbit/s
Modulation: QPSK
SF=256
The E-AGCH bears the E-DCH absolute Grant information of all the UEs in the cell.
The TTI may be 2 ms or 10 ms depending on the E-DCH. If the E-DCH TTI is 10 ms, then the E-AGCH either
sends the same content in five subframes, or sends the content in one of the five subframes.
The UE only monitors the E-AGCH of the E-DCH serving cell.

Rise-over-Thermal Noise
Rise-over-Thermal (RoT) reflects the
measurement value of the uplink load.
In order to correctly demodulate the data
received by the NodeB, the Signal-to-
Interference-Noise Ratio (SINR) must be the
minimum.
The increase of the user number and transmit
power leads to the increase of the uplink
interference.
The NodeB senses the noise raise and SINR is
influenced.
The NodeB controls the total uplink interference
by adjusting the Grant for every UE.
The UE transmits the data based on the Grant,
the volume of data to be sent, and the availabletransmit power.

NodeB Scheduling
UE1 UE2 UE3
The NodeB allocates resources among multiple UEs in the unit of TTI,
and notifies the UE through Grant.
The NodeB tries to satisfy the demand of all online users under the
precondition of preventing overload, maximizing resource utilization ratio,
and maximizing the cell throughput.
The scheduler of HSUPA needs to consider the channel condition, the
data volume to be sent in the UE buffer, and the available transmit powerof the UE.

Implementation of Scheduling
The UE sends a resource request.
The UE reports the Scheduling Information (SI).
The UE reports the happy bit.
The NodeB controls the transmit power of the UE.
The NodeB grants a Traffic-to-Pilot ratio to the UE,
which determines the transmit rate of the UE.
This mode, in which the NodeB grants a T/P value to the
UE, is called scheduled transmission.
The NodeB satisfies the demand of the delay-sensitive
services.
The NodeB adopts the non-grant mode for delay-sensitive
services, that is, the RNC allocates a certain amount of
resources directly to the UE, and the UE can use the
resources at any time rather than waiting for the
scheduling result.
For more
information about
the scheduling, seethe physical channel
part on P31.

HARQ Mechanism
The Stop and Wait (SAW) protocol for multi-channel or multi-process isperformed through four (TTI=10 ms) or eight (TTI=2 ms) processes.
Synchronous retransmission does not need the process number.
Each Radio Link (RL) sends the feedback respectively.
Each RL establishes one E-HICH.
The E-HICH information sent by each Radio Links set (RLs) is the
same and can be combined.
If all E-HICHs return ACK, then the transmission succeeds.
