Radio Resource Management Admission Control Directed Retry Channel Allocation Power Control Hard Handover Soft Handover Load Control The process of determining whether a service request can be admitted to the system The process of re-directing a new user toward a base station different from the one providing best link budget The process of choosing the channel (and the number of RUs) to be allocated to the user The process of setting the transmission power level The process of changing serving base and/or channel The process of modifying the set of serving bases The process of controlling the load of the network
