Channel Mapping

In RAN 10, the mapping from DCCH to HS-DSCH/E-DCH is implemented.



21/59


New 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 the E-DPDCH.

Downlink physical channel

E-HICH: Bears the HARQ ACK/NACK indication message of the E-DCH.

E-AGCH: Bears the absolute grant (AG) information determined by the scheduler.

E-RGCH: Bears the relative grant (RG) information determined by the scheduler.



22/59


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.



30/59


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.

If the cell belongs to the E-DCH serving RLs:

10 ms TTI: The RG information is sent in 12 consecutive slots (8 ms).

2 ms TTI: The RG information is sent in 3 consecutive slots (2 ms).

E-RGCH Timing Relations

When the cell sending the E-RGCH belongs to the E-DCH serving RLs, the E-

RGCH frame offset confirms to the following conditions:

1. If the E-DCH TTI is 10 ms, the E-RGCH frame offset to the P-CCPCH

satisfies the following formula:

2. If the E-DCH TTI is 2 ms, the E-RGCH frame offset to the P-CCPCH

satisfies the following formula:

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.



47/59


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.


I l t ti f S h d li


48/59


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.



49/59


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.

E-DPDCH Gain Factor


54/59


The E-DPDCH has a power offset with the uplink DPCCH.

ed is the gain factor of E-DPDCH.

ed,ref is the gain factor of the reference E-TFC.

ed can be calculated through ed,ref.

E-DPDCH and harq are designated by the higher layer, which can be

specified by the parameter setting.

Reference E-TFC

How to determine the reference E-TFC of each frame?

The reference E-TFC is the system-specified

reference E-TFC.

Suppose the reference E-TFCs are 1, 2, ...m-1,m

(m is the maximum reference E-TFC), then the E-

TFCs between m-1 and m shall take m-1 as the

reference E-TFC.

The E-TFCs larger than m shall take m as thereference E-TFC.

The E-TFCs smaller than 1 shall all select 1 as the

reference E-TFC.

E-AGCH/E-RGCH/E-HICH Power Control

Two power control modes

Static power allocation

P = Pcpich + PowerOffset

Dynamic power allocation (based on the downlink DPCH)

---Every kind of channel can have a different PO. The specificimplementations are different, and are not defined in the protocol.
