    Abstract: A method of downlink control information (DCI) transmission is proposed to enhance DCI transmission efficiency over physical layer signaling in cellular mobile communication networks. A serving base station uses a higher layer signaling, e.g., radio resource control (RRC) signaling message to configure a plurality of user equipments (UEs) to monitor UE-group DCI. When the UE is configured to monitor UE-group DCI, the UE monitors both unicast DCI and UE-group DCI in each corresponding scheduling time unit, e.g., a subframe in LTE. The candidate positions of the unicast DCI and the UE-group DCI can be orthogonal, partially overlapping, or fully overlapping with each other.

    Abstract: A method of two-stage scheduling in downlink control channel is proposed to enhance downlink control information (DCI) forward compatibility and hardware flexibility. The DCI comprises a basic DCI and an extended DCI. The basic DCI provides basic scheduling information of the scheduled data. The extended DCI provides extended scheduling information of the scheduled data channel. The basic DCI can be unicast to a single UE over UE-specific search space. The basic DCI can also be broadcast or multicast to a group of UEs over common search space. UE performs blind detection of the basic DCI only, while the location and size of the extended DCI can be provided by the basic DCI or provided by a higher layer signaling. Cross-slot/subframe and Multi-slot/subframe scheduling can also be applied in the two-stage scheduling.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The UE receives, from a base station, a low-power radio layer (LPRL) synchronization signal on an LPRL for synchronization and measurement. The UE communicates, on the LPRL, wake-up information or paging information with the base station for subsequent communications on a high-performance radio layer (HPRL). The UE detects, on the HPRL, a signal transmitted from the base station.

    Abstract: Various solutions for low-power wake-up signal (LP-WUS) design with respect to user equipment and network node in mobile communications are described. An apparatus may receive a LP-WUS configuration from a network node. The apparatus may receive a LP-WUS based on the LP-WUS configuration from the network node. The apparatus may determine whether to wake up according to the LP-WUS. The LP-WUS with N subcarriers (SCs) is generated through a transformation of M-bit on-off keying (OOK) in a time domain. The transformation is a discrete Fourier transform (DFT) or least square operation. K samples are generated from the M bits with a signal modification or a signal truncation. The LP-WUS is generated through an inverse fast Fourier transform (IFFT) operation. The K is a size of the IFFT operation of cyclic-prefix orthogonal frequency-division multiple access (CP-OFDMA). The N is less than or equal to the K.

    Abstract: Various solutions for improvement of scheduling multi-cell PUSCH/PDSCH transmission with a single DCI are described. An apparatus may receive a DCI scheduling cells from a network node. The DCI includes at least one of a first DCI, a second DCI, and a third DCI. The apparatus may determine a DCI size budget of the DCI counted in one cell. The apparatus may perform a DCI decoding according to the DCI size budget and perform a PDSCH reception or a PUSCH transmission with at least one cell based on the DCI. The first DCI includes a common bit field, a first specific bit field and a plurality of designated bit fields corresponding to the cells, the second DCI includes the common bit field, a second specific bit field and a first part of the designated bit fields, and the third DCI includes a second part of the designated bit fields.

    Abstract: Various solutions for enhancements on paging early indication (PEI) design are described. An apparatus may receive a PEI from a network node of a wireless network. The PEI is included in a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a paging early indication-radio network temporary identifier (PEI-RNTI). The apparatus may monitor a paging occasion (PO) associated with the apparatus in a case that the PEI indicates there being a paging for a subgroup to which the apparatus belongs.

    Abstract: A method for updating tracking reference signal (TRS) configuration and/or TRS availability information to idle mode or inactive mode user equipment (UE) is proposed to reduce/minimize the signaling overhead. A UE operates in an idle mode or an inactive mode of communication with a wireless communication network, and receives a paging downlink control information (DCI) or a paging early indication (PEI) from the wireless communication network. The paging DCI or the PEI includes an indication of system information (SI) update for TRS configuration. Based on the indication of SI update for TRS configuration, the UE receives a SIB including TRS configuration from the wireless communication network. Based on the TRS configuration, the UE receives a TRS from the wireless communication network when the UE is in the idle mode or the inactive mode.
