    Abstract: Technology is disclosed for a user equipment (UE) operable for wake-up signal (WUS) communication in a fifth generation (5G) new radio (NR) network. The UE can be configured to: identify a resource set for a WUS with a repetition level, wherein: the resource set for the WUS includes a mapping of the WUS that associates the WUS with one or more physical resource blocks and one or more orthogonal frequency division multiplexing (OFDM) symbols, and the repetition level identifies a number of base sequences for the WUS in the resource set; and switch to a network access mode (NAM) from a power saving mode (PSM) based on a detection of the WUS in the resource set.

    Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing vehicle-to-everything sidelink communication. A wireless device may receive vehicle-to-everything resource pool configuration information and sidelink control information. A number of resource elements allocated for a vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the resource pool configuration information and the sidelink control information. A transport block size for the vehicle-to-everything physical sidelink shared channel may be determined based at least in part on the number of resource elements allocated for the vehicle-to-everything physical sidelink shared channel. A low density parity check base graph may be selected for the vehicle-to-everything physical sidelink shared channel based at least in part on the determined transport block size.

    Abstract: Techniques discussed herein can facilitate RS (Reference Signal) sequence generation and mapping, and/or precoder assignment, for NR (New Radio). One example embodiment employable at a NR wireless communication device comprises processing circuitry configured to: generate one or more PN (Pseudo Noise) sequences based at least in part on an initial state of a PN generator; extract, for each PRB (Physical Resource Block) of one or more PRBs, an associated portion of an associated PN sequence of the one or more PN sequences, based at least in part on a reference subcarrier index, independent of a bandwidth part configuration and of a maximum supported number of PRBs; and generate, for each PRB of the one or more PRBs, an associated set of RS(s) for that PRB based at least in part on the extracted associated portion of the associated PN sequence for that PRB.

    Abstract: Apparatus that sends uplink control information (UCI) from user equipment (UE) to a network node, generates elements of the UCI including at least one of hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback for one or more uplink (UL) resources, a scheduling request (SR), a channel state information (CSI) report and a beam related information report in response to a trigger set by the network node. The apparatus encodes the UCI elements for transmission via a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) of the one or more UL resources. The one or more UL resources may be UL slots or UL portions of downlink-uplink (DL-UL) slots received from a network node.

    Abstract: The systems, methods, and apparatuses can receive one or more communication signals traversing through a communication channel. The systems, methods, and apparatuses can estimate one or more known parameters, characteristics, and/or attributes of the communication channel, for example, scattering, fading, and/or power decay over distance, through a process referred to as channel estimation. The systems, methods, and apparatuses can develop various channel coefficients, for example, amplitudes and/or phases, describing the channel response of the communication channel at discrete intervals of time, also referred to as taps. The systems, methods, and apparatuses can assign taps to various priorities and, thereafter, utilize these priorities to selectively include their corresponding channel coefficients in a CSI report or exclude their corresponding channel coefficients from the CSI report.

    Abstract: Systems and methods for synchronizing communications between a User Equipment (UE) and Base Station (BS) using a synchronization signal structure. The synchronization signal structure can include a sequence of Synchronization Signals (SS) 5 including repetitions of a synchronization signal burst set. The synchronization signal burst set can include a plurality of synchronization signal bursts. The synchronization signal bursts can include a plurality of synchronization signal blocks, wherein the synchronization signal blocks can include a plurality of Synchronization Signals (SS).
