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 RTD capability indicates a RTD supported by the UE between a first cell and a timing reference cell. 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: Techniques and examples of determination of receiver (RX) beam for radio link monitoring (RLM) based on available spatial quasi-co-location (QCL) information in New Radio (NR) mobile communications are described. An apparatus receives downlink (DL) signaling from a network. The apparatus determines whether to extend an evaluation period of RLM based on a quasi-co-location (QCL) association provided in at least the DL signaling. The apparatus then executes extension of the evaluation period of the RLM, or not, based on a result of the determining.

Abstract: Various solutions for satellite access network (SAN) or non-terrestrial network (NTN) measurement within overlapping gaps with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive configurations of a first measurement gap and a second measurement gap. The apparatus may determine whether the first measurement gap and the second measurement gap are non-fully overlapping or fully overlapping. The apparatus may perform measurements within the first measurement gap and the second measurement gap according to a priority in an event that the first measurement gap and the second measurement gap are non-fully overlapping. The apparatus may perform measurements within an extended measurement period in an event that the first measurement gap and the second measurement gap are fully overlapping.

Abstract: Apparatus and methods are provided for simultaneous DL transmissions. In one novel aspect, performing simultaneous DL transmissions with multiple TCI states is provided. A UE can be configured, by a BS, with a plurality of TCI states. After being configured with the TCI states, the UE can determine multiple TCI states for simultaneous DL transmissions and transmit a report to the BS to inform the BS of that the multiple TCI states are for simultaneous DL transmissions. Then, the UE applies the multiple TCI states for simultaneous DL transmissions.

Abstract: Apparatus and methods are provided for RRM measurement in the NR network. In one novel aspect, the RRM measurement is configured with one measurement gap for SS block and CSI-RS. In one embodiment, an extended MGL (eMGL) is configured such that the SS block and CSI-RS is measurement within one measurement gap. In another embodiment, the shorter MGL (sMGL) that is shorter than the standard MGL is configured. In another novel aspect, the CSI-RS is allocated adjacent to the SS blocks such that one measurement gap is configured for both the SS block and CSI-RS measurement. In another novel aspect, the CSI-RS measurement is conditionally configured. In yet another novel aspect, the UE decodes the time index of the SS block conditionally.

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: 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: 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 performing received signal strength indication (RSSI) measurements in new radio (NR) networks is proposed. When RSSI-Measurement time slots and OFDM symbols are configured by high-layer signaling, UE can assume the timing reference of a target carrier is the frame boundary of the serving cell or any detected cells on that carrier. UE then performs RSSI measurements according to the timing reference and the configured RSSI-Measurement slot/symbol. UE derives the timing location of the configured slot/symbol according to the timing reference and the subcarrier spacing (SCS) of the synchronization signal block (SSB) in the target carrier.
