Abstract: An apparatus and system for power saving in a user equipment (UE) are described. The UE uses signal-to-interference-plus-noise (SINR) of radio link monitoring (REM) signals to determine whether to enter or exit a relaxation state in which the frequency of measurement of the REM signals is reduced, as is feedback to the base station. The REM relaxation state is dependent on the average SINR of the REM signals over a predetermined time window. Alternatively, the REM relaxation state is dependent on SINR thresholds that include an SINR fluctuation range using a SINR threshold for REM in-sync or derived from a Cumulative Distribution Function (CDF) curve of SINR using a predetermined maximum SINR fluctuation.

Abstract: A computer-readable storage medium stores instructions to configure a UE for radio resource management (RRM) measurements in a 5G NR. network, and to cause the UE to perform operations. The operations include decoding RRC signaling. The RRC signaling includes system information associated with an inter-RAT cell of a. target base station. The system information includes an indicator for support of enhanced RRM measurements by the inter-RAT cell. Configuration information from a. source base station is decoded. The configuration information includes a handover instruction for performing a handover from the source base station to the target base station. A determination is made whether to perform the enhanced RRM measurements and the handover based on the indicator.

Abstract: An apparatus and system for setting an uplink timing advance (TA) for a non-terrestrial network (NTN) user equipment (UE) are described. The NTN UE estimates and updates a UE-specific TA value each period. The update is based on Global Navigation Satellite System (GNSS) positions and satellite ephemeris information. The NTN UE adjusts the UE-specific TA gradually, between a predetermined minimum and maximum aggregate adjustment rate.

Abstract: An apparatus and system of establishing receive timing difference (RTD) for high subcarrier spacing (SCS) are described. The RTD is dependent on whether carrier aggregation (CA) or dual connectivity (DC) is used. For CA, RTD reflects the entire time difference between carriers caused by a Timing Alignment Error (TAE) and propagation delay difference between slots aligned at transmission. For DC, RTD is between the closest slot boundaries and reflects only slot boundary misalignment without considering the slot index.
