The process of radio resource management is a process of controlling interference within the system zPower is the ultimate radio resource. The only way to use radio resources most effectively is to strictly control the use of power. 2 Course Objectives After completing this course, you will be able to zUnderstand the purpose of radio resource management, understand basic radio resource management algorithms, channel configuration, power control, mobility management, load control, AMR mode control, etc. z3 Course Contents Chapter 1 Overview of Radio Resource Management Chapter 2 Channel Configuration Chapter 3 Power Control Chapter 4 Connection Mobility Management Chapter 5 Load Control Chapter 6 AMR Mode Control Training.huawei.com 4 Overview of Radio Resource Management zRadio Resource Management (RRM) WCDMA system is a self-interference system. The process of radio resource management is a process of controlling interference within the system zPower is the ultimate radio resource. The only way to use radio resources most effectively is to strictly control the use of power. The use of power is contradictory in CDMA systems. zIncreasing the transmit power for a certain user can improve the service quality of that user. On the other hand, an increase in interference will cause a decrease in reception quality for other users due to the self-interference of the CDMA system. 5 Several conceptszzSeveral conceptsUTRAN, RAB RB RL UTRAN provides services such as establishment and release of radio access bearers (RAB) to the non-access stratum NAS to shield NAS from the concerns of the radio access stratum.
