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: 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.
