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: 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.

Abstract: A vehicle may wirelessly communicate with another vehicle via a physical channel (a vehicle-to-vehicle (V2V) channel) that is robust and reliable under high mobility propagation conditions. The physical channel may be created by modifying an existing long-term evolution (LTE) physical channel, such as an LTE sidelink (SL) channel. For instance, the V2V physical channel may be created by increasing, by a particular factor, the subcarrier spacing of legacy LTE channels (e.g., from 15 kilohertz (kHz) to 30 kHz). Additionally, a symbol duration and a fast physical channel may each be reduced by Fourier transform (FFT) size for the V2V the same factor. Doing so may enable the V2V physical channel to be implemented without significant modifications to other aspects of the LTE standard.

Abstract: A user equipment (UE) configured for multi-antenna communication estimates at least one of a rank indicator and a channel quality indicator for device to device (D2D) based on communication data associated with a plurality of packets communicated using D2D communication and without using a dedicated reference signal for D2D communication. The UE may be configured as at least one of a transmitter (Tx) and a receiver (Rx) for vehicle-to-everything (V2X) communication through a sidelink channel.

Abstract: Devices and systems of sensing, resource selection and control signaling for feedback-less and feedback-based NR-V2X sidelink communication are described. Resource reservation and selection for sidelink retransmissions based on HARQ feedback are described for unicast, groupcast, and broadcast blind retransmissions. After exchanging HARQ feedback capability information for different types of communications, a HARQ-dependent or HARQ-independent resource selection occurs. Look-ahead and/or chain-based resource selection and reservation signaling is used, in which a single resource or some or all of the resources selected are signaled as reserved. Further resource selection of a single additional resource may occur after an initial resource selection. The resource selection for retransmissions may be adapted using a RSRP or distance threshold.

Abstract: A design for reference signals dedicated for positioning measurements in UL and DL directions and a mechanism for Tx/Rx beam pair selection for positioning is disclosed. The design can improve performance of positioning operation in NR communication systems, can improve resource efficiency of positioning operation in NR communication systems, and can reduce the amount of resources needed for PRS transmission, reduce latency and increase the positioning measurement quality.

Abstract: A user equipment (UE) configured for New Radio (NR) vehicle-to-everything (V2X) (NR V2X) sidelink transmission in a fifth generation (5G) network may determine a transport block size (TBS) for transmission of a transport block (TB) within a current sidelink slot. The UE is configured to encode a physical sidelink shared channel (PSCCH) for transmission within the current sidelink slot. The PSCCH may be encoded to include sidelink control information (SCI). The SCI may indicate a reservation of physical sidelink shared channel (PSSCH) resources within up to three sidelink slots including the current sidelink slot 102. To determine the TBS, the UE may determine number of resource elements (REs) within the current sidelink slot 102 that are available for transmission of the PSSCH by excluding certain REs of the current sidelink slot.

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 PSSCH 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: An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for Reference Signal Time Difference (RSTD)-based 5G-NR positioning. The processing circuitry is to determine a first PRS BW associated with a first PRS received from a first gNB associated with a first cell. A second PRS BW is determined, which is associated with a second PRS received from a second gNB of a second cell. An RSTD report resolution is determined based on the first PRS BW and the second PRS BW. A receive (Rx) timing difference between the first cell and the second cell is measured based on reception times of the first PRS and the second PRS. The measured Rx timing difference is mapped into an RSTD report for transmission to the first gNB, based on the RSTD report resolution.

One example apparatus configured to be employed within a user equipment (UE) comprises receiver circuitry, a processor, and transmitter circuitry. The receiver circuitry can receive, from each of a plurality of evolved Node Bs (eNBs), one or more RSs of each of a plurality of distinct types of RSs. The processor can determine, for each of the eNBs, a time of arrival (TOA) of the one or more RSs of each of the plurality of distinct types of RSs; and compute, for each of the eNBs, a reference signal time difference (RSTD) based at least in part on the TOAs of the one or more RSs of each of the plurality of distinct types of RSs. The transmitter circuitry can transmit the RSTD computed for each of the eNBs.

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may allocate a resource pool of physical resource blocks (PRBs) and sub-frames for vehicle-to-vehicle (V2V) sidelink transmissions. The gNB may receive, from a UE, an uplink control message that indicates that the UE requests a V2V sidelink transmission of a prioritized message. The gNB may select, for the V2V sidelink transmission of the prioritized message, one or more PRBs and one or more sub-frames. The gNB may transmit, to the UE and to other UEs, a downlink control message that indicates: the selected PRBs, the selected sub-frames, and that the other UEs are to mute sidelink transmissions in the selected PRBs in the selected sub-frames to enable the V2V sidelink transmission of the prioritized message.

Abstract: Systems and methods of providing NR V2V communications are disclosed. Channel sensing is used by both UEs to determine sets of candidate resources, and subsequently select a resource, for PSCCH and PSSCH transmissions. The transmitting UE selects the PSCCH resource and transmits a scheduling request using the PSCCH resource, while the receiving UE selects a PSCCH and the PSSCH resource and transmits a scheduling grant in the PSCCH containing transmission parameters and the PSSCH resource to the transmitting UE. When the scheduling request contains the candidate resources for the PSCCH transmission, the receiving UE uses the intersection of the candidate resources for the PSCCH transmission and the candidate resources for transmission to determine the PSCCH and the PSSCH resource.

In some embodiments, sidelink control signalling supports the reservation and indication of multiple sidelink resources.

Abstract: A user equipment (UE) can receive, from an eNodeB, a serving PLMN system information block (SIB)19 for a carrier frequency of a serving PLMN of the UE.
