Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.

Abstract: Described is an apparatus of an Evolved Node-B (eNB) operable to communicate with a User Equipment (UE) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, a third circuitry, and a fourth circuitry. The first circuitry may be operable to identify a data block having a number N1 of bits. The second circuitry may be operable to determine a number N2 of filler bits based on a set of one or more parameters and the N1 of bits of the data block. The third circuitry may be operable to pad the data block with the N2 filler bits to form a padded data block having a number N3 of bits. The fourth circuitry may be operable to encode the N3 bits of the padded data block to form a polar codeword having a number N4 of bits.

Abstract: Techniques discussed herein can facilitate polar coding and decoding for NR (New Radio) systems. Various embodiments discussed herein can employ polar coding and/or decoding at UE(s) (User Equipment(s)) and/or gNB(s) (next generation Node B(s)). One example embodiment employable at a UE can comprise processing circuitry configured to determine one or more thresholds for code block segmentation, wherein the one or more thresholds for code block segmentation comprise one or more of a payload threshold (Kseg) or a code rate threshold (Rseg); determine to perform code block segmentation based on the one or more thresholds and at least one of a current payload (K) of an information block or a current code rate (R) for the information block; segment the information block into a plurality of segments; and encode each segment of the plurality of segments via a polar encoder with a code size (N).

Abstract: Described herein are methods and apparatus for jointly encoding components of a a channel state information (CSI) report into a single codeword. Padding bits are added to equalize payload size for different CRI/RI cases and to allow encoding of all parts of CSI into one codeword without payload ambiguity.
