Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may perform a slot reservation procedure to obtain a TxOP for communicating with a second UE. The slot reservation procedure may be performed in an earliest slot in the TxOP in which the first UE has data to send to the second UE. The apparatus may transmit the data to the second UE using at least one slot in the TxOP when the slot reservation procedure is successful. In certain aspects, all remaining slots in the TxOP may be reserved for the first UE when the slot reservation procedure is successful. The apparatus may refrain from performing a subsequent slot reservation procedure in another slot in the TxOP when the slot reservation procedure is unsuccessful unless an end of transmission signal is received during the TxOP.

Abstract: A network architecture is disclosed with support for location services (LCS). A radio access network (RAN) node receives a registration request from a user equipment (UE), indicating that the UE supports a ranging based location service session. The RAN node further receives an internal identifier (ID) for identifying information associated with the UE in communication between the RAN node and a core network during the ranging based location service session. The RAN node allocates radio resources to the UE for performing a ranging operation involving a plurality of devices including the UE, and associates the radio resources with the internal ID of the UE for identifying location results. Then the RAN node informs the UE of the radio resources allocated for the ranging operation.

Abstract: Methods, systems, and devices for ranging are described. A multi-phase distributed ranging technique includes transmitting and receiving vehicle information messages during a first time interval, where the vehicle information messages include at least a vehicle identifier and resource information. The multi-phase technique further includes transmitting and receiving ranging signals during a second time interval, and determining times of arrival of received ranging signals. A centralized ranging technique includes receiving resource assignments from an access point, transmitting ranging signals according to the resource assignments, and determining times of arrival of received ranging signals.

Abstract: Aspects of the present disclosure are directed to device-to-device (D2D) and, more particularly, vehicle-to-vehicle (V2V) communication in which an efficient ranging protocol allows efficient ranging-assisted vehicle positioning. A vehicle transmits a first slot ID in a first control period, to indicate a first time slot for transmitting a first ranging signal in a ranging cycle including a plurality of time slots. The vehicle transmits the first ranging signal in the first time slot in the ranging cycle. From a second vehicle, the first vehicle receives a second ranging signal in a second time slot that is different from the first time slot in the ranging cycle. The first vehicle determines a first time-of-arrival (ToA) of the second ranging signal when received by the first vehicle, and transmits the first ToA in a second control period.

Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to achieve communications between the distributed UEs with high reliability and low latency. A transmitting UE can configure an ultra-reliable low-latency communication (URLLC) transmission unit by configuring a URLLC channel indicator, a URLLC transmission indicator, a URLLC control channel, and URLLC data portion. The UE can transmit the configured URLLC transmission unit in punctured OFDM symbols within a regular subframe to a receiving UE in the distributed C-V2X environment.

Abstract: The present aspects relate to device-to-device (D2D) relaying in a wireless communication system. In an aspect, a relay user equipment (UE) may receive, on a downlink channel from a network entity, at least one indication including resource allocation information for at least one of the relay UE or a remote UE. The relay UE may further transmit, on a sidelink channel to the remote UE, the resource allocation information of the remote UE. In another aspect, a remote UE may receive, on at least one sidelink channel, resource allocation information from a relay UE, the resource allocation information indicating one or more resources allocated for sidelink communication for the remote UE. The remote UE may further transmit, on one or more sidelink channels, data to the relay UE in accordance with the one or more resources allocated for sidelink communication.

Abstract: A cross-carrier scheduling scheme is provided. The cross-carrier scheduling scheme may improve the resource scheduling, for example, in V2X communication. The apparatus (e.g., a UE) receives a resource grant on a first carrier for a second carrier, the resource grant assigning resources for the second carrier. The apparatus communicates with a second UE via the second carrier using the granted resources. The apparatus may apply the resource grant based on at least one offset, such as an offset between the timing of the first carrier and timing of the second carrier.
