Abstract: Techniques and examples of overhead reduction for linear combination codebook and feedback mechanism in mobile communications are described. A user equipment (UE) receives from a base station of a network one or more reference signals via a communication link between the UE and the base station. The UE constructs a channel state information (CSI) feedback by utilizing a correlation of channel responses in a frequency domain to reduce feedback overhead. The UE then transmits the CSI feedback to the 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: Techniques and examples of evaluation period for radio link monitoring (RLM) in New Radio (NR) mobile communications are described. An apparatus performs RLM with respect to a radio link with a cell of a wireless network. In performing the RLM, the apparatus determines whether an RLM reference signal (RLM-RS) is overlapped with one or more other reference signals and, responsive to a result of the determining indicating that the RLM-RS is at least partially overlapped with the one or more other reference signals, extends an evaluation period for the RLM.

Abstract: Various solutions for handling aperiodic reference signal (RS) with respect to user equipment (UE) in mobile communications are described. A UE may receive aperiodic RS information from a network apparatus. The UE may determine whether aperiodic RS is presented. If the aperiodic RS is not presented, the UE may perform first data decoding procedure. If the aperiodic RS is presented, the UE may perform second data decoding procedure according to the aperiodic RS information. The UE may further determine whether a trigger command for triggering channel state information (CSI) reporting is presented. The UE may perform CSI measurement according to the aperiodic RS information if the trigger command is presented and transmit a CSI report to the network apparatus.

Abstract: Narrowband downlink control channel (NB-PDCCH) design for Narrowband Internet of Thing (IoT) devices is proposed. In one novel aspect, NB-PDCCH spans both first and second slots in the region of legacy physical downlink shared channel (PDSCH). A plurality of physical resource blocks (PRBs) is allocated for NB-PDCCH transmission that carry downlink control information (DCI). Furthermore, each NB-IoT device can be configured with nPRB PRB pairs for NB-PDCCH transmission (e.g., nPRB=1, 2, 4, or 8), and an NB-PDCCH transmission time interval (TTI) is composed by nPRB subframes. An NB-PDCCH is encoded and occupies multiple narrowband control channel elements (NCCEs) based on aggregation level. In a preferred embodiment, each PRB pair for NB-PDCCH occupies two NCCEs.

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.
