Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.

Abstract: Apparatuses, systems and methods associated with asynchronous synchronization reference source selection and reselection for wireless communication devices are disclosed herein. In embodiments, one or more non-transitory, computer-readable media having instructions stored thereon, wherein the instructions, in response to execution by a user equipment (UE), cause the UE to establish a sidelink connection with a first synchronization reference (SyncRef) UE, and monitor for physical sidelink broadcast channel (PSBCH) synchronization signals from a second SyncRefUE, wherein the UE is to drop one or more subframes of data reception of the sidelink connection with the first SyncRef UE when the UE monitors for the PSBCH synchronization signals. Other embodiments may be described and/or claimed.

Abstract: Systems and methods provide solutions for testing an 8Rx capable UE using test cases for 4Rx capable UEs. An example method establishes a connection from a first Tx source and a second Tx source to each of 8Rx antenna ports. The connection duplicates a fading channel from both the first Tx source and the second Tx source to each of the eight Rx antenna ports, and adds independent noise for each of the 8Rx antenna ports. One test scenario uses 4Rx supported RF bands by connecting four of the Rx ports with data from a system simulator, and the other four Rx ports are connected with zero input. Same requirements specified with 4Rx capable UEs are applied. Another test scenario uses 8Rx supported RF bands and applies lower dB SNR requirements than those specified for 4Rx tests.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE receive training signals from a plurality of transmit-receive points (TRPs) associated with the gNB. Each training signal may comprise a reference signal resource identifier (ID) to indicate a corresponding TRP and a corresponding transmit direction of a plurality of transmit directions. The UE may, for each transmit direction of the plurality of transmit directions, determine an average signal quality measurement based on individual signal quality measurements in multiple receive directions. The UE may select, for reporting to the gNB, a subset of the average signal quality measurements to ensure that the average signal quality measurements excluded from the subset are less than or equal to a minimum value of the average signal quality measurements in the subset.

Abstract: Devices and methods provide for transmitting downlink (DL) positioning reference signals (PRSs) in a wireless system. A DL PRS resource pool is configured and divided into a plurality of DL PRS resource sets. The DL PRS resource pool includes a periodically repeated amount of resources dedicated for DL PRS transmission by a plurality of gNBs in the wireless communication system. The plurality of DL PRS resource sets correspond to one or more gNB of the plurality of the gNBs. The DL PRSs are encoded for transmission on configured DL PRS resources within the plurality of DL PRS resource sets.

Abstract: Implementations of this disclosure generally may relate to the field of wireless communications. More specifically, implementations described in this disclosure relate to different 3GPP LTE and LTE-A system enhancements to address the issue and support reliable V2X operation in the high mobility environments. Several solutions to improve the V2X system performance in the high mobility vehicular channel propagation conditions are described. Some aspects relate to the suggestion of a new DMRS patterns within individual subframes that promote more accurate CFO estimation. Moreover, another aspect provides DMRS mapping or puncturing patterns to transmit individual DMRS in a periodic pattern on respective OFDM/SC-FDMA symbols so that they do not occupy all REs of the OFDM/SC-FDMA symbols, respectively.

Abstract: Some embodiments of this disclosure are directed to apparatuses and method for establishing signal-to-noise ratio (SNR), useful signal power level (Es) and artificial noise power level (Noc) values for new radio (NR) performance requirements. The apparatuses and methods can include processing a received signal including the Es and Noc and determining a baseband signal-to-noise ratio (SNR) degradation based on the signal power level, the artificial noise power level, and the radio-frequency noise power level. The apparatuses and methods can then determine a compensated SNR degradation, as a performance requirement, based on the baseband SNR degradation and the radio-frequency noise power level.
