Abstract: A method of determining the maximum timing change (MTC) based on subcarrier spacing (SCS) configuration for UE measurement and reporting of a neighbor cell in 5 GS is proposed. During measurement procedure, UE first checks whether a neighbor cell has been detectable at least for the time period Tidentity, and becomes undetectable for a period ?5 seconds, and then the cell becomes detectable again. UE then determines the MTC of the cell according to the SCS configuration of the cell. If the timing change of the cell is <MTC, UE reports the measurement report less than a first period (T1) after the measurement event is triggered. Otherwise, if the timing change of the cell is >MTC, UE reports the event triggered measurement reporting less than a second period (T2) after the measurement event is triggered.

Abstract: A method is provided for TCI switching related to CSI-RS measurement and reporting, spatial relation switch for SRS, PUSCH, and PUCCH. The PDSCH and PDCCH are received according to the QCLed aperiodic CSI-RS. When the AP CSI-RS is configured as the reference in the TCI of PDSCH, UE may apply the updated TCI for the PDSCH, after the corresponding aperiodic report has been received at the network. Spatial relation switch is based on the valid measurement report. The spatial relation switch delay of aperiodic SRS can be performed when UE has sent the corresponding measurement report to the network.

Abstract: Aspects of the disclosure provide an electronic device including a transceiver and processing circuitry and a method for scheduling restriction. The transceiver can receive from a network configuration information to configure a measurement resource for a signal quality measurement. The signal quality measurement can determine a signal quality of a reference signal from the network to the electronic device. The processing circuitry can determine whether to apply the scheduling restriction based on the configuration information. In response to applying the scheduling restriction, the processing circuitry can determine when to apply the scheduling restriction based at least on a resource type of the measurement resource, the resource type being one of periodic, semi-persistent, and aperiodic. In an example, the signal quality of the reference signal includes a layer 1 (L1) reference signal received power (L1-RSRP) for the reference signal and the signal quality measurement includes an L1-RSRP measurement.

Abstract: A user equipment terminal (UE) in a wireless network calculates a measurement period for measuring the signal-to-interference-plus-noise ratio (SINR) for a serving cell within a frequency range. The calculation is based on a channel measurement resource (CMR) and an interference measurement resource (IMR). The calculation includes evaluation of a sharing factor P, which is a maximum of PCMR of the CMR and PIMR of the IMR. The PCMR and the PIMR are evaluated, at least in part, based on periodicity of the CMR and the IMR in relation to other periodic measurements performed by the UE. The UE performs a channel measurement and an interference measurement using the CMR and the IMR, respectively, over the measurement period. The UE calculates the SINR based on the channel measurement and the interference measurement; and transmits an SINR measurement report indicating the calculated SINR to a base station.

Specifically, for SCell BFR procedure, a sharing factor K is introduced when multiple SCells are configured to perform BFR procedure. In one embodiment, the SCell BFR evaluation period equals to a predefined PCell BFR evaluation period times the sharing factor K.

Abstract: Aspects of the disclosure provide apparatuses and methods for wireless communications. One apparatus includes processing circuitry that selects one or more first available radio link monitoring reference signal (RLM-RS) samples from a plurality of received RLM-RS samples based on signal qualities of the one or more first available RLM-RS samples. The one or more first available RLM-RS samples are received within a first evaluation period. The processing circuitry determines whether a total number of the one or more first available RLM-RS samples is less than a target number. When the total number of the one or more first available RLM-RS samples is determined to be less than the target number, the processing circuitry determines a second evaluation period that is greater than the first evaluation period, and performs an RLM procedure in an unlicensed band within the second evaluation period.

Different criteria for UE to enter and exit the relaxed RLM/BFD measurement state are proposed. In relaxed measurement state, UE can perform RLM/BFD measurements with an extended evaluation period by a scaling factor K when the serving cell quality is higher than a threshold and/or when the serving cell quality variation is lower than a threshold within a time period.
