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: A new design for physical downlink control channel (PDCCH) is proposed for the next generation 5G new radio systems. A UE receives the configuration of a default control resource set (CORESET) in MIB/SIB from its serving base station. The default CORESET contains both common search space and UE-specific search space for candidate PDCCH transmission. A PDCCH in a default CORESET is mapped to physical resource in a distributed or localized manner. Specifically, various REG-to-CCE mapping rules are proposed to improve frequency diversity gain, or frequency selectivity gain, or to reduce latency of PDCCH processing. Further, to facilitate analog beamforming in mmWave systems, the default CORESET is transmitted in a synchronization signal (SS) block associated with a corresponding analog beam direction.

Abstract: A method of introducing a Downlink Control Information (DCI)-based early paging indication (PEI) for power consumption enhancements in a 5G/NR network is proposed. In particular, a Base Station (BS) can transmit a message including a PEI to a User Equipment (UE) when the UE is under an idle ode. Then, the UE can receive the PEI under the idle mode and determine whether to monitor a Paging Occasion (PO) according to the PEI. In some embodiments, a format of the message including the PEI can include a format of DCI.

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 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 method of providing early paging indication (PEI) for power consumption enhancements in a 5G/NR network is proposed. Under the novel paging reception procedure with PEI, UE can skip PO monitoring if PEI indicates negative. The UE main receiver is typically turned on in every paging cycle, for LOOP, MEAS, and PEI reception. However, if PEI indicates no paging, then UE can turn off its main receiver right after performing measurements. Since PEIs are always transmitted and are located near synchronization signal block (SSB) bursts, power saving can be achieved not only for PO monitoring but also for light sleep between the last SSB/PEI and the PO monitoring gap and state transitions, when no UE in the UE group is paged.
