Abstract: Various features described herein relate to DM-RS design for a control channel and a data channel that maybe used for vehicular communications. In an aspect, a UE may determine a base DM-RS sequence associated with a control channel for V2V communication. The UE may further determine a DM-RS sequence based on the base DM-RS sequence and an identity of the UE, and transmit a plurality of DM-RS symbols within the control channel in a subframe using the DM-RS sequence. In another aspect, a UE may generate a plurality of DM-RS sequences, each DM-RS sequence maybe generated for a corresponding DM-RS symbol of a plurality of DM-RS symbols associated with a data channel for V2V communication based on a DM-RS symbol number of the corresponding DM-RS symbol. The UE may transmit the plurality of DM-RS symbols within the data channel in a subframe using the plurality of DM-RS sequences.

Abstract: During device-to-device communication between two devices, a communication transmitted from a first UE to a second UE may not be reliably received by the second UE if the first UE is traveling at high speed. Therefore, a travel speed of a transmitting UE may be considered in determining a transmission configuration. According to an aspect, the UE may determine a travel speed of the UE. The UE may determine, based on the travel speed of the UE, a transmission configuration of the UE for device-to-device communication. The UE may transmit the device-to-device communication based on the transmission configuration.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The apparatus may transmit a message in a first subset of a set of resources. The message may include a position of the apparatus and a resource ID indicating at least one symbol in a second subset of the set of resources for transmitting a sequence. The apparatus may transmit the sequence in the at least one symbol in the second subset of the set of resources identified by the resource ID, receive at least one other sequence, adjust a transmission timing based on the received at least one other sequence, and transmit, based on the adjusted transmission timing, the sequence in one or more symbols in a third subset of the set of resources.

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: Features of the present disclosure implementing techniques that allow the user equipment (UE) to autonomously (e.g., without the network control) manage timing synchronization of a plurality of carriers using sidelink synchronization signal (SLSS) from one or more other UEs in order to identify a synchronization source. A synchronization source associated with a frequency carrier from a set of frequency carriers may be selected according to one or more SLSS sync source selection techniques or rules. For instance, the described solution may be utilized to enable UEs to autonomously perform V2X carrier aggregation (CA). In some examples, the synchronization carrier(s) to be searched may be determined based on the SLSS capability of the UE (e.g., transmission and reception of SLSS capabilities of the UE).

Abstract: An apparatus for wireless communication of a UE determines to transmit data in a set of RBs to at least one other UE in at least one subframe. The at least one subframe includes a first subset of symbols configured for use for transmission collision avoidance signaling and a second subset of symbols configured for transmitting the data. The apparatus determines a subset of symbols of the first set of symbols within the set of RBs of the at least one subframe for transmitting at least one concatenated sequence. The apparatus transmits the at least one concatenated sequence in each symbol of the determined subset of symbols within the set of RBs of the at least one subframe to indicate that the data will be transmitted in the second set of symbols within the set of RBs of the at least one subframe.
