    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: 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.

    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 for providing tracking reference signal (TRS) availability information to idle mode or inactive mode user equipment (UE) is proposed to enhance the TRS-based power saving design. A UE operates in an idle mode or an inactive mode of communication with a wireless communication network, and receives a system information block (SIB) from the wireless communication network when the UE is operating in the idle mode or the inactive mode. The received SIB includes TRS configuration. The UE determines whether a TRS is present on a TRS occasion indicated by the TRS configuration based on TRS availability information signaled from the wireless communication network, and receives the TRS from the wireless communication network in response to determining that the TRS is present.
