RNC Tasks and Functions

WCDMA radio resource managementincl. Radio resource management of channel configurations,

traffic and control channels, handovers, power control.

Telecom functionalityincl. Location & connection management, ciphering, Iu and Iub

channel management, ATM switching and multiplexing

Maintenanceincl. Fault localisation and reconfiguration

Operationincl. RNC and Node B parameter modification



Node B Tasks and Functions

IubInterfaceATM

UuInterfaceWCDMA

Cellular Transmission management

Managing ATM switching and multiplexingover the Iub interface. Control of AAL2/AAL5

connections. Control of the physicaltransmission interfaces E1, PDH, SDH or

microwave.

Air Interface management.

Controlling Uplink and Downlinkradio paths on the Uu Air

Interface. Baseband to RFconversion. Antenna multi-

coupling.

O&M Processing.Interfacing with NMS

and RNC for alarm andcontrol (Operations andMaintenance) functions.

Radio Channel functions.Logical to physical channel

mappings. Encoding/Decoding

Spreading/Despreading usertraffic and signalling.

Key WCDMA Facts

Duplex Transmission Modes: Frequency Division Duplex (FDD)

Time Division Duplex (TDD)

Multiple Access:

Code Division Multiple Access (CDMA)

Modulation (Rel. 99) Quadratur Phase Shift Keying (QPSK)

Bandwidth (Rel. 99)

5 MHz

Time Organisation:

10 ms per radio frame

15 time slots per frame

72 radio frames per hyperframe

2560 chips per timeslot

Spreading

Spreading codes =

channelisation codes scrambling codes

Chip rate: 3.84 Mchips

Channelisation codes = orthogonal codes,

length: depends on spreading factor

Scrambling codes = pseudo noise codes

(derived from Gold code family)

length: 38400 chips (10 ms)

Spreading Factors (FDD mode):

UL: 4, 8, 16, 32, 64, 128, 256

DL: 4, 8, 16, 32, 64, 128, 256, 512

The spreading factor can be changed every

TTI (10, 20, 40, or 80 ms).

Handover types: Soft & Softer HO (FDD only),

Hard Handover;
