"A Survey on Radio Resources Management in UMTS W-CDMA Networks"


By Mr. Hailiang Wu


Abstract:

W-CDMA is the most widely adopted air interface in third generation
systems, it provides high user data rates and supports services with
variable data rates and different Quality of Service (QoS) requirements.
The capacity of the W-CDMA network is mainly limited by the interference
from the all of users in the system. To reduce the interference from
other users and  maintain the SIR in a target level is important for
services with QoS. The radio resource management, including power
control, packet data scheduling, call admission control, load control and
handover control, plays an important role in increasing system capacity
and throughput, and guaranteeing QoS for users.

This survey studies the principle, characteristics, and architecture of
UMTS wideband CDMA system, and then investigates the radio resource
management strategies, especially the call admission
control algorithms and packet data scheduling schemes for wideband CDMA
networks.
