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: The implementations disclosed provide apparatus, systems, and methods for channel structure construction for a two-step random access channel (RACH) using a new radio (NR) user equipment (UE) wireless device. The wireless device includes one or more computer processors configured to generate a physical RACH (PRACH) preamble mapped to a physical uplink shared channel (PUSCH) resource unit. The PRACH preamble is associated with a preamble group indicating a configuration of the PUSCH. The preamble group has a size indicated by radio resource control (RRC) signaling performed by the wireless device. A message is encoded including the PRACH preamble and a payload carried by the PUSCH. The configuration of the PUSCH includes parameters for decoding the message. The wireless device couples communicatively to a base station using the PUSCH. The message is transmitted to the base station. The base station decodes the message based on the parameters of the PUSCH configuration.

Abstract: Technology for a user equipment, operable to configure a control resource set (CORESET) is disclosed. The UE can decode a signal, received from a next generation node B (gNB), that includes a resource element group (REG) bundling size for a first CORESET. The UE can decode a signal, received from the gNB that includes a REG bundling size for a second CORESET. The UE can decode a control message contained in one or more REGs in one or more of the first CORESET or the second CORESET.

Abstract: Methods and apparatus are described for transmitting uplink control information (UCI) over an OFDMA-based uplink. In some embodiments, UCI symbols are mapped to resource elements (REs) in the time/frequency resource grid to maximize frequency diversity. In some embodiments, UCI is mapped in a manner that takes into account channel estimation performance by mapping UCI symbols to those REs that are closest (in terms of OFDM subcarriers/symbols) to REs that carry reference signals.

Abstract: Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods for communication are generally described herein. The UE may receive downlink control information (DCI) that schedules a transport block (TB) that includes multiple code blocks. The UE may determine a transport block size (TBS) based on the DCI. The UE may attempt to decode the code blocks. The UE may, if the TBS is greater than a predetermined threshold: bundle the code blocks into code block groups for hybrid automatic repeat request (HARQ) acknowledgement; and transmit a HARQ bit per code block group. The UE may, if the TBS is less than or equal to the threshold, transmit a HARQ bit that indicates whether a decode failure has occurred for at least one of the code blocks of the TB.

Abstract: Techniques discussed herein can facilitate handling of DL (Downlink) control and data channels having different numerologies in NR (New Radio). One example embodiment comprises an apparatus employable by a UE (User Equipment) configured to generate a report comprising capability information associated with the UE, wherein the capability information indicates whether the UE supports multiplexing of multiple numerologies within a common symbol in a FDM (Frequency Division Multiplexing)-based manner; process first higher layer signaling that configures one or more control resource sets of a NR (New Radio) PDCCH (Physical Downlink Control Channel), wherein the one or more control resource sets are associated with one or more numerologies in accordance with the UE capability information; and demodulate a NR PDSCH (Physical Downlink Shared Channel) from a resource distinct from resources of the NR PDCCH.
