Abstract: Apparatus and methods are provided for NR CSI-RS based BFD/RLM in FR2. In one novel aspect, BFD in FR2, the evaluation period is extended by the N factor if the CSI-RS for BFD is in a resource set configured with repetition ON or the BFD is performed on CSI-RS#1 without beam information or, where the CSI-RS#1 is configured without beam information if CSI-RS for BFD is not QCL-TypeD with SSB for L1-RSRP beam reporting, nor the CSI-RS for BFD is not QCL-TypeD with CSI-RS for L1-RSRP beam reporting. In one embodiment, the N factor equals to 1 only when at least one predefined RX beam information is included in the RRC configuration. In another embodiment, the predefined RX beam information for BFD is Type-D QCL information for a synchronization signal block (SSB) configured in its TCI state or the CSI-RS#1 is configured with repetition ON.

Abstract: User equipment (UE) for Received Signal Strength Indicator (RSSI) measurement is provided. The UE may include a radio frequency (RF) signal processing device and a processor. The RF signal processing device receives an RSSI measurement. The processor is coupled to the RF signal processing device.

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.

Abstract: Methods are proposed to define UE behavior for performing synchronization signal block (SSB) based radio link monitoring (RLM) and channel state information reference signal (CSI-RS) based RLM. In a first novel aspect, if CSI-RS based RLM-RS is not QCLed to any CORESET, then UE determines that CSI-RS RLM configuration is error and does not perform RLM accordingly. In a second novel aspect, SSB for RLM and RLM CSI-RS resources are configured with different numerologies. UE perform SSB based RLM and CSI-RS based RLM based on whether the SSB and CSI-RS resources are TDMed configured by the network. In a third novel aspect, when multiple SMTC configurations are configured to UE, UE determines an SMTC period and whether SMTC and RLM-RS are overlapped for the purpose of RLM evaluation period determination.

Abstract: A method of activating multiple secondary cells can include receiving on a primary cell (PCell) at a user equipment (UE) a first medium access (MAC) control element (CE) for activating a first secondary cell (SCell) and a second SCell for the UE in a wireless communication system. The first and second SCells can operate in a same band. No active serving cell operates on the same band for the UE. In response to that the first SCell is a known SCell, the second SCell is an unknown SCell, and both the first and second SCells operate in the same band that is a frequency range 2 (FR2) band, the first and second SCells can be activated in parallel without performing cell search and reference signal received power (RSRP) measurement and reporting over the first and second SCells.

Abstract: Methods and apparatus of performing spatial relation switching in new radio (NR) system is proposed. In one embodiment, a configured spatial relation of an uplink channel is Quasi-Co-Located (QCLed) to the source of a downlink reference signal (DL RS).

In another embodiment, the configured spatial relation is QCLed to the root source of an uplink sounding reference signal (SRS). In this QCLed relation, the active spatial relation switching does not need to differentiate known and unknown situation. The proposed spatial relation switching shall apply for physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), and SRS transmission.

In one novel aspect, the CBD evaluation period uses the uniformed scaling factor and the base period for the CBD evaluation period is the same when no DRX is configured and when the DRX is configured with DRX cycle length smaller than or equals to a predefined threshold. In one embodiment, the UE receives DRX configuration including a DRX cycle length, determines a base period for an evaluation period of CBD measurements based on the DRX cycle length and determines a multiplicator for the evaluation period based on a scaling factor and one or more measurement factors, and performs CBD measurements based on the evaluation period, wherein the evaluation period is based on the determined base period and the multiplicator. In one embodiment, the scaling factor is the same for all DRX configurations.

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.

The UE refrains from conducting measurements of the first reference signal, when the physical layer signaling is detected by the UE and includes a first indication.

Abstract: Aspects of the disclosure provide a method and an apparatus. For example, the apparatus can include receiving circuitry and processing circuitry. The receiving circuitry can be configured to receive from a cell a Q number and one or more SSBs within DRS transmission windows associated with the cell. The processing circuitry can be configured to, for each of the DRS transmission windows, perform a modulo operation on position indexes of the SSB with the Q number to determine SSB beam indexes (SBIs) of the SSBs. A remainder of each of the position indexes is an SBI of one of the SSBs that corresponds to the position index. The processing circuitry can be further configured to combine RRM measurements of the SSBs within the DRS transmission windows based on the SBIs of the SSBs to determine the quality of the cell.

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.
