Abstract: Various solutions for enhancements on paging early indication-occasion (PEI-O) monitoring are described. An apparatus may receive a first radio resource control (RRC) parameter from a network node. The first RRC parameter indicates an offset before a first paging frame (PF). The apparatus may determine a time location of a PEI-O according to a reference point determined by the offset. The PEI-O is associated with one or more paging occasions (POs) in one or more paging frames (PFs) starting from the first PF. The apparatus may monitor the PEI-O to detect whether a PEI is received from the network node. The PEI indicates whether there is a paging for a subgroup to which the apparatus belongs.

Abstract: A communication apparatus includes a low power wakeup receiver (LP-WUR) and a processor. The processor is configured to receive signals from a network apparatus via the LP-WUR, and perform operations including: receiving at least one synchronization signal sent by the network apparatus, wherein the at least one synchronization signal comprises at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS); and using the at least one synchronization signal to detect timing of a low power wakeup signal (LP-WUS).

Abstract: Examples pertaining to synchronization and radio resource management in mobile communications are described. A user equipment (UE) receives a periodic low power synchronization signal (LP-SS) from a network node via a low-power wake-up receiver (LP-WUR) of the apparatus. Then, the UE performs a synchronization based on the periodic LP-SS via the LP-WUR of the apparatus in an event that a main radio of the apparatus is in a power saving mode. The synchronization comprises at least a coarse time synchronization and a coarse frequency synchronization.

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: A communication apparatus includes a low power wakeup receiver (LP-WUR) and a processor. The processor is configured to perform operations including: receiving a modulated signal from a network apparatus via the LP-WUR, wherein the modulated signal has a harmonized design that accommodates overlaid waveforms of one or more modulation schemes; and deriving information bits from demodulating the modulated signal.

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: Various solutions for low-power wake-up signal (LP-WUS) monitoring with respect to user equipment and network node in mobile communications are described. An apparatus may receive a configuration from a network node. The apparatus may comprise a main radio (MR) and a lower-power wake-up radio (LP-WUR). The apparatus may determine whether to activate or deactivate a low-power wake-up signal (LP-WUS) monitoring by the LP-WUR according to at least one pre-configured condition in the configuration. The apparatus may receive an LP-WUS from the network node via the LP-WUR in an event that the LP-WUS monitoring is activated.

Abstract: A method for Downlink Control Information (DCI)-based Physical Downlink Control Channel (PDCCH) monitoring adaptation is proposed. A User Equipment (UE) performs a Discontinuous Reception (DRX) operation. The UE detects a UE-specific DCI format during the DRX operation, wherein the UE-specific DCI format includes a bit field that indicates an adaptation on PDCCH monitoring. The UE adjusts a PDCCH monitoring periodicity in a DRX active time of the DRX operation according to the bit field.
