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: Various examples with respect to synchronization signal block (SSB) raster shift in mobile communications are described. A processor of a user equipment (UE) performs an initial cell search to identify a cell among one or more cells of a wireless communication system. The processor then camps on the identified cell. In performing the initial cell search, the processor scans through a plurality of SSB entries for frequency bands below 3 GHz with a SSB raster spacing and a SSB raster offset frequency that support sub-carrier spacing (SCS) spaced channel raster and 100 kHz channel raster for both 15 kHz SCS and 30 kHz SCS. A minimum channel bandwidth at 5 MHz or higher for 15 kHz SCS or at 10 MHz or higher for 30 kHz SCS is supported. The SSB raster spacing is a common multiple of 15 kHz and 100 kHz. The SSB raster offset frequency for 100 kHz channel raster is a multiple of 30 kHz plus/minus 10 kHz.

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: 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: 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.

Abstract: A method for expediting Secondary Cell (SCell) or Primary cell of a secondary cell group (PSCell) addition or activation is proposed. A User Equipment (UE) receives a command that indicates adding or activating an SCell or a PSCell, wherein the command comprises information of a temporary Reference Signal (RS). The UE detects the temporary RS according to the information, and uses the temporary RS to add or activate the SCell or the PSCell.

Abstract: Methods to support measurements for LTE user equipments are proposed. Due to reduced bandwidth design for cost reduction, resources for UEs are limited to contiguous six physical resource block (PRB) pairs (1.4 MHz). Six or less contiguous PRBs per narrow sub-band located in the whole channel bandwidth is allocated for transmission and reception for UEs. Novel control channel and data channel designs are proposed to make UEs be able to camp on LTE cells. Methods for intra-frequency measurement, for received signal time difference (RSTD) measurement, and for channel quality assessment for UEs are also provided. In one embodiment, UE is allocated with a measurement gap for intra-frequency measurements and RSTD measurements. In another embodiment, UE is configured with a frequency-hopping pattern and receives a PRB pair starting index per subframe for CSI measurement.
