    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: A method and apparatus for performing channel coding type control are provided, where the method may include: obtaining a code block size to be used during channel encoding (or decoding) for a Transport Format (TF); comparing the code block size with at least one predetermined threshold to generate at least one comparison result; selecting a specific channel coding type from a plurality of channel coding types according to the at least one comparison result; and utilizing the specific channel coding type during channel encoding (or decoding) for the TF. It is an advantage that the method can utilize code-block-size-dependent channel coding types during channel encoding (or decoding), so the channel coding gain can be increased, and therefore the goal of improving the system capacity and reducing the power consumption can be achieved.

    Abstract translation: 提供一种用于执行信道编码类型控制的方法和装置，其中所述方法可以包括：获得要在传输格式（TF）的信道编码（或解码）期间使用的码块大小; 将码块大小与至少一个预定阈值进行比较以产生至少一个比较结果; 根据所述至少一个比较结果从多个信道编码类型中选择特定信道编码类型; 并且在针对TF的信道编码（或解码）期间利用特定信道编码类型。 该方法在信道编码（或解码）期间可以利用基于码块尺寸的信道编码类型是有利的，因此可以增加信道编码增益，从而提高系统容量并降低功耗 可以实现。

    Abstract: Examples pertaining to network energy saving in spatial and power domains in mobile communications are described. A user equipment (UE) receives a report configuration from a network node having a plurality of antenna ports and transmits a measurement report based on the report configuration. The report configuration comprises information regarding at least one adaptation pattern associated with a measurement resource configuration and indicating at least one of a target number of the antenna ports and a power offset value configured by the network node.

    Abstract: Apparatus and methods are provided for TxRU carrier switch. In one embodiment, the UE is configured with an anchor carrier in an anchor cell and one or more secondary carriers. In one embodiment, the TxRU carrier switch is configured as supplementary uplink (SUL)-based carrier switch with supplementary carriers or configured as a CA-based carrier switch with supplementary cells. In one embodiment, the one or more secondary carriers are supplementary carriers of the anchor cell, and wherein the anchor carrier is TDD carrier or frequency division duplex (FDD) carrier, and wherein the supplementary carrier is configured as a TDD carrier, a FDD carrier, a supplementary uplink carrier (SUL), or a supplementary downlink carrier (SDL). In another embodiment, the one or more secondary carriers are supplementary cells different from the anchor cell, and wherein the supplementary cells are configured with MAC control element (CE).
