description: Long Term Measurement (LTM) is a procedure in the 5G New Radio (NR) protocol that involves the configuration and management of long-term measurements for radio resource control. The LTM-Candidate information element, as described in the provided paragraph from 3GPP TS 38.331, contains various parameters related to the configuration of LTM candidates, such as the LTM candidate ID, physical cell ID, SSB configuration, and more. These configurations are used to manage and optimize radio resources in the network.
explanation: LTM is classified as a procedure because it involves a series of steps and configurations for managing long-term measurements in the 5G NR protocol. The provided paragraph from the 3GPP specification outlines the structure and parameters involved in LTM candidate configuration, highlighting its role in radio resource control.
