Conditions for planning
** Conditions :
• capacity not constant.
• separate analysis for UL/DL.
• joint coverage/capacity analysis.
• HO areas and levels affect directly system capacity.
• basic shared resource is power.
** Objective parameters :
• coverage.
• capacity (blocking).
• good link quality (BER, FER).
• throughput delay, for packet services Methods.
• preplanned during network planning process.
• real time radio resource management.
• real time power control.
Network planning
Resource reservation for handling expected traffic without congestion.
– load per cell/sector, handover areas.
Sets allowable “power budget” available for services.
– load higher than expected.
– load “badly” distributed.
– implements statistical multiplexing.
Estimates average power/load, variations of it are taken care in run time by RRM.
– maximal allowed load versus average load.
