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: 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 method of performing beam failure recovery (BFR) procedure in primary cell and secondary cells with reduced UE complexity is proposed. A UE is configured to operate in one or multiple frequency bands under carrier aggregation or dual connectivity. The UE performs beam failure recovery (BFR) procedure on one serving cell for one frequency band across FR1 and FR2. The serving cell is an active serving cell including both primary cell (PCell) and secondary cells (SCells). 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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The method may be performed by a UE. In certain configurations, the UE transmits, to a base station, a received timing difference (RTD) capability of the UE.

The UE receives, from the base station, an instruction of a configuration, which is determined according to the RTD capability of the UE. The UE performs the configuration according to the instruction. The RTD capability of the UE may include a parameter indicating the UE supporting advanced RTD capability or limited RTD capability.

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 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.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The method may be performed by a UE. In certain configurations, the UE performs a procedure resulting in a status change of a first pre-configured measurement gap (pre-MG) of a pre-MG activation procedure. The UE determines whether the pre-MG activation procedure collides with or is overlapped with an overlapping gap. In response to determining that the pre-MG activation procedure collides with or is overlapped with the overlapping gap, the UE configures a pre-MG activation delay for the first pre-MG after an end of the overlapping gap, and performs the pre-MG activation procedure in the first pre-MG after the pre-MG activation delay.

Abstract: A method for expediting Secondary Cell (SCell) activation is proposed. Under the proposed enhanced direct SCell activation procedure, while adding an SCell to be activated state, the network can add transmission configuration indication (TCI) state information for the SCell in a radio resource control (RRC) signaling message, in addition to TCI state information for a list of candidate TCI states. Upon receiving the RRC signaling message, UE adds the SCell accordingly, and then activates the SCell based on the received TCI state information. Because there is no additional time required for receiving and processing the TCI state information via a media access control (MAC) control element (CE), the SCell activation time is reduced.

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.
