Channelization Code:• Using Orthogonal Variable Spreading Factor

(OVSF) codes• Fully orthogonal, i.e. do not interfere with

each other• Used to separate different users/cell• Limited codes per cell• Once a code is chosen, any codes on the

same branch above or below the used code cannot be used (refer diagram below)

SOFT HANDOVERActive Set:Up to 3 cells in soft handover (sHO), i.e. 3 AS. This means a UE can be served by up to 3 cells at the same time. Note that 3 AS equals to using 3 cells’ resources at the same time.

AS

Things to defineMotorola: inter_rat_enabled, 2g>3g neighbours1

Ericsson: qsi, 2g>3g neighbours

Parameter

1 Can be checked with the file Motorola Dump Formatter.xls in \\sgbsvc112\share06\04_3G MSEP\02 Cell Dumps\2 Can be checked with the file 3G Ericsson Dump Compiler v1.5.xls or 3G Siemens Dump Compiler v2.0.xls in \\sgbsvc112\

share06\04_3G MSEP\02 Cell Dumps\

Monitored Neigbour / Detected NeighbourMonitored Neighbour (MN): Neighbour already

defined2, can be added as an AS if criterion is metDetected Neighbour (DN): Neighbour not defined in the

neighbour list, need to be added TWO-WAY if it is a valid missing neighbour. A DN whose RSCP is too close to the strongest server and not added as a neighbour will become an interferer.

OPTIMIZATION

TEMS Snapshot

RSCP = COVERAGEIt is equivalent to RxLev in GSM

Coverage

Ec/No = QUALITYIt is equivalent to RxQual in GSM. Very important to optimize network to have good quality (>-12dB)

Quality

OPTIMIZATION CONCEPT• To have best Ec/No (not necessarily RSCP) by

minimizing other cell’s interference. This means optimizing a cell’s coverage with balancing between RSCP and Ec/No.

• Ideally, at one point in time, you should have only 1AS only. But for practicality, it should be less than 3 cells (including best server) within 6dB of the best server’s RSCP (above example would have 4 cells)

3G Opti METHODS OF OPTIMIZATION• Tilting of overshooting site• Power down of overshooting site with max tilts• Neighbour addition of DN’s• Reengineering, e.g. antenna swing

Methods

Common Pilot ChannelUse for channel estimation reference at the terminal; scrambled with cell specific primary SC; DL channel with a fixed rate of 30 kbps or SF256

RESOURCES & CAPACITY

NODE BNODE B

E1 CAPACITYType: Site-levelNote: This resource is for signaling and traffic between Node B and RNC (highest priority among all resources mentioned here).Congestion Resolution: E1 upgrade

IUB

CHANNEL ELEMENTType: Site-level Note: This resource shared between sectors within one NodeB. It is used to process different type of services, e.g. CS, PS, HSDPA, 1 CE = 1 Voice CallCongestion Resolution: Channel card activation or addition

CE/CHC

POWERType: Cell-levelNote: Output power on the downlink is shared between UE’s.for their respective trafficCongestion Resolution: Power upgrade or 2nd Carrier

POWER

CODEType: Cell-levelNote: This is referring to the channelization/OVSF code resource which is one per service (more codes for HSDPA)Congestion Resolution: 2nd Carrier
