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: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB), Evolved Node-B (eNB) and methods of communication are generally described herein. The UE may detect one or more LTE synchronization signals from an eNB over an LTE Uu interface between the UE and the eNB. The LTE synchronization signals may be detected in resources allocated for LTE communication. The LTE synchronization signals may be detected in accordance with an LTE protocol. The UE may determine, based on the LTE synchronization signals, a reference timing and a reference frequency for NR vehicle-to-everything (V2X) communication over an NR PC5 interface with another UE.

Abstract: User equipment (UE) positioning within a 5G New Radio (NR) network may be determined by receiving a downlink (DL) position reference signal (PRS) resource set indicating a plurality of DL PRS resources and receiving a DL PRS report configuration that indicates a set of measurements to be performed by a UE for each of the plurality of DL PRS resources within the DL PRS resource set. Position measurements may be performed for each of the plurality of DL PRS resources within the DL PRS resource set, including generating a reference signal time difference (RSTD) measurement by estimating a timing of a first arrival path from at least two of the plurality of DL PRS resources and determining a reference signal received power (RSRP) metric or a signal to noise and interference ratio (SINR) metric associated with the at least two DL PRS resources. The performed position measurements may be reported.

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: A method for allocating channel resources for transmitting data by user equipment (UE), includes receiving a resource allocation specification for a PSCCH transmission on PSSCH resources. The resource allocation specifies a PSCCH decoding unit of N symbols by M PRBs. The decoding unit is larger than a resource element group (REG) associated with the PSSCH resources. The method includes causing transmission, by a transceiver, of the PSCCH transmission in using the decoding unit specified by the resource allocation specification.

Abstract: Systems and methods of providing RAT co-existence and congestion control in V2V communications are generally described. A vUE detects specific non-LTE RAT transmissions in a listening period of a PSCCH or PSSCH, determines whether a metric has been met and reselects to a non-overloaded channel to communicate with other vUEs or the eNB. The manner of reselection is dependent on the RAT specific or V2X service priorities of the channels, as well as whether the channels are V2V service dependent.

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.
