Channel MappingChannel Mapping

We do not provide the mapping from DCCH to HS-DSCH/E-DCH for the time being.

New Channels in HSUPANew Channels in HSUPA

Uplink transport channel E-DCH: Bears high-speed uplink data.

Uplink physical channel E-DPDCH: Bears E-DCH PDUs. E-DPCCH: Bears the control information of E-DPDCH.

Downlink physical channel E-HICH: Bears the HARQ ACK/NACK indication message of E-

DCH. E-AGCH: Bears the Absolute Grant information determined by

the scheduler. E-RGCH : Bears the Relative Grant information determined by

the scheduler.

Physical Layer Information Exchange Process of HSUPAPhysical Layer Information

Exchange Process of HSUPA

① The UE sends an SI request carrying Buffer

state, UPH and other relevant information

via the E-DPDCH.

② The NodeB allocates resources via the E-

AGCH to the UE (absolute grant procedure)

or indicates power adjustment via E-RGCH

(relative grant procedure).

③ The UE sends MAC-e PDU (service or

signaling data) via the E-DPDCH, and sends

via the E-DPCCH the control information and

Happy bit (indicating the UE’s satisfaction

towards the rate currently allocated) that are

needed to demodulate the PDU.

④ The NodeB replies via the E-HICH to the

UE, telling the UE whether the PDU has

been successfully demodulated.

Grant MechanismGrant Mechanism

Absolute Grant Borne by the E-AGCH of the E-DCH serving cell

Grant mode: An index (totally 31 index values) used to indicate

the Traffic-to-Pilot ratio (E-DPDCH/DPCCH)

Significance of the grant value: The maximum power ratio

available for the UE (E-DPDCH/DPCCH)

Relative Grant RG carries a command instructing the UE to

increase/hold/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 non E-DCH

serving RLs

Downlink ChannelDownlink Channel

E-AGCH Bears the maximum allowed E-

DPDCH/DPCCH ratio

Rise-over-Thermal NoiseRise-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 causes uplink interference

to raise

The NodeB senses the noise raise and

SINR is influenced

The NodeB controls the total uplink

interference by adjusting the Grant to

every UE

The UE selects to send data according to

the Grant, the volume of data to be sent

and the available transmit power.

NodeB Scheduling NodeB Scheduling

UE1 UE2 UE3

Quickly allocate resources among multiple UEs in the unit of TTI and notify the UEs via Grant.

Try the best to satisfy all online users on the precondition of preventing overload, maximizing resource utilization and maximizing the cell throughput.

The scheduler of HSUPA needs to consider these factors: Channel condition, the volume of data to be sent in the UE buffer and the available transmit power of the UE.

Implementation of SchedulingImplementation of Scheduling

The UE sending a resource request The UE reports the Scheduling Information (SI).

The UE reports the Happy bit.

Controlling the UE transmit power The NodeB grants a Traffic-to-Pilot ratio to the UE,

which determines the available transmit rate of the UE.

The mode in which the NodeB grants a T/P value to

the UE is called “Scheduled transmission”.

Satisfying delay-sensitive services Use the non-grant mode for delay-sensitive services,

that is, the RNC directly allocates a certain amount of

resource to the UE, and the UE may use this resource

at any time without waiting for the scheduling result.

See the physical channel part for the scheduling

process

HARQ MechanismHARQ Mechanism

Multi-channel (process) Stop And Wait (SAW) protocol; 4

(TTI: 10 ms) or 8 (TTI: 2ms) processes

Synchronous retransmission without the process number

Every Radio Link (RL) will give a separate feedback.

Every RL has one E-HICH established.

The E-HICH information sent by every Radio Links set (RLs) is

the same and can be combined.

Transmission succeeds once any E-HICH returns ACK.
