    Abstract: A method to improve the design of new radio physical downlink control channel (NR-PDCCH) transmission and to reduce the false alarm rate of NR-PDCCH blind decoding is proposed. The downlink control information (DCI) bits are carried by NR-PDCCH to be transmitted to UEs after CRC attachment, channel encoding, interleaving, and modulation. The proposed NR-PDCCH design is separated into two parts. In a first part, a UE-ID or RNTI is used to derive a CRC mask or a scrambling sequence for CRC attachment of the DCI bits. In a second part, a UE-specific ID is used to derive an interleaver before or after channel encoding of the DCI bits. If the interleaver is placed before channel encoding, it takes the form of a bit interleaver. If the interleaver is placed after channel encoding, it takes the form of a bit interleaver or a channel interleaver.

    Abstract: Apparatus and methods are provided for polar code sub-block interleaving and bit selection. In one novel aspect, middle-part interlaced sub-block interleaving is provided for polar code interleaving. In one embodiment, the middle part of the polar code is interlaced and generates the interleaved polar code. In another embodiment, the lower part and the upper part are also sub-block interleaved with the middle-part interlaced method. In another novel, rate-dependent unified bit selection is provided. The bit selection is categorized into three operation categories of repetition, puncturing and the shortening. Each category follows unified bit selection rule with different categories differ only in the access scheme. In one embodiment, the circular buffer is used for bit selection.

    Abstract: A method and apparatus for performing channel coding control are provided. The method may include: adding CRC bits to information bits, for performing channel encoding corresponding to the electronic device to generate an encoding result; performing data arrangement corresponding to the electronic device on at least one of the encoding result and a derivative thereof to generate a data arrangement result, for use of generating a processing result corresponding to the electronic device; and transmitting the processing result corresponding to the electronic device to UE. More particularly, for a same set of information bits to be transmitted from a plurality of electronic devices including the electronic device to the UE, the encoding result could be different from that in any other electronic device within the electronic devices, and a coding chain represented by the data arrangement result is different from that in any other electronic device within the electronic devices.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receiving a unified waveform signal from a base station, wherein the unified waveform signal comprises an On-Off Keying (OOK) signal and an Orthogonal Frequency Division Multiplexing (OFDM) signal; determining whether an indicator in the OFDM signal indicates that the unified waveform signal is a low-power wake-up signal (LP-WUS); decoding the LP-WUS when the indicator indicates that the unified waveform signal is the LP-WUS; and terminating a decoding operation when the indicator indicates that the unified waveform signal is not the LP-WUS.

    Abstract: Various solutions for low power wake-up signal (LP-WUS) transmission with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a wake-up signal (WUS) configuration from a network node. The apparatus may monitor a wake-up signal based on the WUS configuration. The wake-up signal may be modulated based on one-off keying (OOK) and generated by a multi-carrier amplitude shift-keying (MC-ASK) waveform generation, and wherein a parameter K is a size of inverse fast Fourier transform (IFFT) of cyclic-prefix orthogonal frequency-division multiple access (CP-OFDMA).

    Abstract: A method of supporting active bandwidth part (BWP) switching under carrier aggregation (CA) is proposed. To avoid longer switching delay and multiple interruptions in other component carriers (CCs)/cells, the starting time of the later active BWP switching in one cell should fall outside the switching delay of the earlier active BWP switching in another cell. If the later active BWP switching is DCI-based, then the network should schedule the later active BWP switching outside the switching delay of the earlier active BWP switching. If the later active BWP switching is timer-based, then the UE should not perform the later active BWP switching until the earlier active BWP switching is completed.
