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: Examples pertaining to determining transmission configuration indicator (TCI) for received signal strength indicator (RSSI) measurement in mobile communications are described. A user equipment (UE) determines a quasi-co-location (QCL) assumption with respect to a received signal strength indicator (RSSI) responsive to not receiving a TCI from a network. The UE also performs an RSSI measurement based on the determined QCL assumption in an expanded Frequency Range 2 (FR2-2) band according to a 3rd Generation Partnership Project (3GPP) specification.

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 event triggered measurement reporting less than a second period (T2) after the measurement event is triggered.

Abstract: An apparatus receives, from a wireless network, a transmission configuration indication (TCI) switch command to switch to a target TCI state. The apparatus determines a period based on whether a condition with respect to the target TCI state is met. The apparatus then completes switching to the target TCI state within the period.

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: 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 channel state information reference signal (CSI-RS) radio resource management (RRM) measurement is proposed. A UE receives RRM measurement configuration from a BS via RRC signaling. The RRM measurement configuration comprises CSI-RS resource information, cell IDs, and associated SSB indication. The UE decides frequency resources of CSI-RS according to the configured RRC parameters. UE performs cell search within synchronization signal block (SSB) measurement timing configuration (SMTC) window to know the detected SSBs and the corresponding detected cell IDs and symbol timing of detected cells. UE then decides timing resources of the CSI-RS according to the timing reference. If the detected cell ID matches the cell ID configured for the CSI-RS resource, UE performs measurements on the CSI-RS resources based on the symbol timing of the detected SSB.
