Abstract: Various solutions for multi-radio access technology (RAT) spectrum sharing in mobile communications are described. An apparatus utilizing a first RAT may transmit user equipment (UE) capability information to a first network node of the first RAT, wherein the UE capability information indicates that the apparatus supports multi-RAT spectrum sharing (MRSS). Then, the apparatus may receive a signaling from the first network node, wherein the signaling indicates the apparatus to provide channel information for MRSS. Based on the signaling, the apparatus may perform at least one of the following: (i) transmitting a measurement report of a channel state information-reference signal (CSI-RS) of a second RAT to the first network node; and (ii) transmitting a sounding reference signal (SRS) or a physical random access channel (PRACH) to a second network node of the second RAT.

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: Examples pertaining to network energy saving in mobile communications are described. A user equipment (UE) receives a report configuration from a network apparatus. The report configuration includes a list of sub-configurations, and each sub-configuration corresponds to an antenna port subset which indicates one or more enabled or disabled antenna ports of a plurality of antenna ports of the network apparatus. The UE then transmit a measurement report of a channel state information-reference signal (CSI-RS) based on the report configuration.

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 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.

Abstract: A method of providing paging early indication (PEI) for power consumption enhancements in a 5G/NR network is proposed. In accordance with one novel aspect, UE subgrouping is used to indicate whether some UEs (a subgroup) among those UEs monitoring the same paging occasion needs to read paging. The UE subgroup can be grouped based on different factors, e.g., power consumption profiled (PCP), or paging probability. The UE subgroup has a reduced number of UEs, with a reduced false alarm rate for paging, at thus a reduced power consumption. In one preferred embodiment, the PEI contains a bitmap, each bit indicates if a subgroup of UEs monitoring the same PO needs to read paging.
