LoggedMeasurementConfiguration (LoggedMeasurementConfiguration-r16)

RRC message · TS 38.331 v19.4.0 (2026-09) · clause 6.2.2

LoggedMeasurementConfiguration-r16 is an RRC message of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.

First seen v16.0.0 (2020-04) · Last changed v19.0.0 (2025-10), in LoggedMeasurementConfiguration-v1800-IEs

Definition

The LoggedMeasurementConfiguration message is used to perform logging of measurement results while in RRC_IDLE or RRC_INACTIVE. It is used to transfer the logged measurement configuration for network performance optimisation.
