Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Abstract: Techniques related to physical uplink control channel procedures are described. Briefly, in accordance with one embodiment, an Uplink Control Information (UCI) payload size is determined based at least in part on configuration information and Downlink Control Information (DCI). A Fifth Generation (5G) Physical Uplink Control Channel (xPUCCH) format is then determined based at least in part on the determined UCI payload size. Other embodiments are also disclosed and claimed.

Abstract: Provided herein are method and apparatus for channel coding in the fifth Generation (5G) New Radio (NR) system. An embodiment provides an apparatus for a Next Generation NodeB (gNB), including circuitry, which is configured to: generate Downlink Control Information (DCI) payload for a NR-Physical Downlink Control Channel (NR-PDCCH); attach Cyclic Redundancy Check (CRC) to the DCI payload; mask the CRC with an Radio Network Temporary Identifier (RNTI) using a bitwise modulus 2 addition operation, wherein the number of bits for the RNTI is different from the number of bits for the CRC; and perform polar encoding for the DCI payload with the masked CRC.

Abstract: Techniques discussed herein facilitate polar coding and decoding for NR (New Radio) systems between UE(s) (User Equipment(s)) and/or gNB(s) (next generation Node B(s)) based on code block segmentation. One example embodiment employable at a UE comprises processing circuitry configured to determine one or more thresholds for code block segmentation, where the one or more thresholds for code block segmentation includes 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: Techniques are described relating to hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a HARQ-ACK aggregation window. A User Equipment (UE) may receive control information (e.g., downlink control information (DCI) or radio resource control (RRC) signaling) from a base station including HARQ-ACK codebook information. The HARQ-ACK codebook information may include information on a size of a HARQ-ACK aggregation window. The UE may decode physical downlink shared channel (PDSCH) transmissions and encode corresponding HARQ-ACK feedback using the HARQ-ACK aggregation window based on the control signaling.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. A channel state information (CSI) report may include a CSI part 1 transmission and may be configurable to include a CSI part 2 transmission. The UE may determine a first number of coded modulation symbols per layer to be used for the CSI part 1 transmission on a physical uplink shared channel (PUSCH) without uplink shared channel (UL-SCH) data. The first number of coded modulation symbols per layer may be determined as: a minimum of a first term and a second term if the CSI report includes the CSI part 2 transmission; and the second term if the CSI report does not include the CSI part 2 transmission.

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.
