Adaptive Modulation and Coding. MIMO Cell scope: Radio Admission Control. RRM Framework Functional Description of the different RRM Modules • Radio Admission Control : Admission control will be in charge of deciding when new users (or mobility users) are allowed to establish bearers in the cell • Handover control: Is in charge of the mobility control within the LTE RRM. OLLA): AMC will perform link adaptation tasks to ensure radio resources are used in the most efficient way possible. • AMC (OLQC. the location and the amount of resources allocated to each user. PS will decide which users are scheduled on a TTI basis. 14 RA41211EN70GLA0 © Nokia Solutions and Networks 2015 . Spatial multiplexing or dynamic switching between previous two modes will be employed for every user based on UE feedback • Power control: For DL it will be a semi static configuration but for UL RRM will provide feedback for closed loop power control to reduce UL interference. Based on UE reported events it will select the appropriate target cell for HO and initiate mobility procedures. • Packet Scheduler: Is in charge of UL and DL scheduling every TTI and resource allocation. • MIMO: This module is in charge of selecting whether Transmit diversity.
