The performed position measurements may be reported.

Abstract: Embodiments of a User Equipment (UE) and methods for communication are generally described herein. The UE may select, from a plurality of short transmission time intervals (TTIs), a short TTI for a vehicle-to-vehicle (V2V) sidelink transmission by the UE. The short TTIs may occur within a legacy TTL. The short TTIs may be allocated for V2V sidelink transmissions by nonlegacy UEs. The legacy TTI may be allocated for V2V sidelink transmissions by legacy UEs. The UE may transmit, in accordance with the legacy TTI, a legacy physical sidelink control channel (PSCCH) to indicate, to legacy UEs, the V2V sidelink transmission by the UE.

Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for New Radio (NR) vehicle-to-everything (V2X) sidelink communication. The processing circuitry is to determine a set of candidate resources of the UE from a sidelink resource pool, the sidelink resource divided into multiple time slots, frequency channels, and frequency sub-channels. Sidelink control information (SCI) is encoded for transmission to a second UE via a physical sidelink control channel (PSCCH). The SCI indicates a plurality of transmission resources of the set of candidate resources. A transport block is mapped across the plurality of transmission resources. A physical sidelink shared channel (PSSCH) is encoded for transmission to the second UE using the plurality of transmission resources, the PSSCH encoded to include the mapped transport block.

Abstract: Techniques for sidelink resource selection, reselection, and reevaluation are disclosed. An apparatus for a user equipment (UE) includes processing circuitry coupled to memory. To configure the UE for 5G-NR sidelink communications, the processing circuitry is to decode an SCI format received via a PSCCH. The SCI format includes priority information for a scheduled PSSCH transmission. RRC signaling is decoded to determine first configuration information and second configuration information. The first configuration information identifies a sensing window, and the second configuration information identifies a resource selection window. A boundary of the resource selection window is based on the priority information. A set of candidate single-slot resources is determined during the sensing window using a resource pool. A resource is selected during the resource selection window from the set of candidate single-slot resources.

Abstract: A computer-readable storage medium stores instructions to configure a UE for sidelink operation in a 5G NR network, and to cause the UE to perform operations including decoding a first sidelink transmission received from a second UE. The first sidelink transmission includes a first resource reservation for a subsequent sidelink transmission by the second UE. A second sidelink transmission received from a third UE is decoded. The second sidelink transmission includes a second resource reservation for a subsequent sidelink transmission by the third UE. A co-channel collision is detected based on the first resource reservation and the second resource reservation being in a same sidelink slot. A feedback message is encoded for transmission to the second UE and the third UE. The feedback message indicates the co-channel collision.

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: Systems and methods are provided to determine an estimated location of a user equipment (UE). For instance, a UE can provide a positioning request to a node while the UE is in a radio resource control idle (RRC_IDLE) or inactive (RRC_INACTIVE) state. The positioning request can be implemented in a random access channel (RACH) message A (MsgA). The UE can then receive a positioning response from the node. The positioning response can be implemented in a RACH message B (MsgB).

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein.

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: 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 Fourier transform (FFT) size for the V2V physical channel may each be reduced by 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: An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for 5G-NR sidelink communications, the processing circuitry is to decode SCI received from a second UE via a PSCCH, the SCI indicating a sidelink resource for transmission of a transport block during multiple transmission time intervals, and a PSFCH indicator. A PSSCH is decoded to obtain the transport block, the PSSCH received in one of the multiple transmission time intervals using frequency resource assignment and time resource assignment of the sidelink resource. HARQ feedback information for the decoded PSSCH is encoded for transmission to the second UE using a PSFCH associated with the sidelink resource, based on the PSFCH indicator and a time gap configured by higher layer signaling.

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 determine, based on one or more detected synchronization signals, a reference timing to be used for a common synchronization of Long Term Evolution (LTE) sidelink communication on an LTE PC5 interface and New Radio (NR) sidelink communication on an NR PC5 interface in accordance with time division multiplexing (TDM) operation, wherein subframe boundaries of the LTE PC5 interface and the NR PC5 interface are aligned in time. If the UE detects, during a time period, an in-device conflict between a service configured for the LTE PC5 interface and a service configured for the NR PC5 interface, the UE may determine which of the services to support during the time period based on corresponding priorities.

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.
