Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a configuration indicating multicast broadcast single frequency network (MBSFN) subframes within a radio frame. The configuration indicates a number of symbols of an MBSFN subframe for receiving a wide area network (WAN) control signal and remaining symbols of the MBSFN subframe dedicated for peer-to-peer communication. The apparatus communicates with a peer via the symbols dedicated for peer-to-peer communication. Alternatively, the apparatus receives a configuration indicating a portion at a beginning and/or end of a guard period of a special time division duplex (TDD) subframe. The portion is reserved for an uplink timing advance and/or switching from transmission to reception and/or reception to transmission. The configuration also indicates a remaining portion of the guard period of the special TDD subframe for peer-to-peer communication. The apparatus communicates with a peer via the remaining portion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify the UE is associated with a vehicle, such as being within the vehicle, or has established connectivity with the vehicle. The UE may transmit location information of the vehicle and one or more vehicle parameters to a network entity, such as a roadside unit (RSU) or a base station. The network entity may identify route data, safety data, or both. The network entity may transmit the route data, the safety data, or both to the UE.

Abstract: Aspects of the present disclosure provide techniques for utilizing road side unit (RSU) that may be stationary units or mobile user equipments (UEs) (e.g., part of a vehicle) for managing scheduling requests from one or more UEs for side-link cellular vehicle-to-everything (CV2X) communication between UEs. To this end, an RSU may determine characteristics associated with the scheduling requests (e.g., traffic type, latency requirements, etc.) to allocate resources in the resource pool to the one or more UEs that comply with the half-duplex constraints.

Abstract: An apparatus may comprise a component for communicating using a first RAT and another component for communicating using a second RAT. Overlapping communication using the two RATs may cause problems for proper reception at the apparatus. The apparatus may detect that transmission or reception of a first packet using a first RAT will overlap in time with reception of a second packet using a second RAT. The apparatus prioritizes the first packet or the second packet based at least on a relative priority of the first packet and the second packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a device-to-device communication with another UE, a modulation and coding scheme (MCS) configuration, of a set of MCS configurations, based at least in part on at least one of a transmission mode, a packet characteristic, a mobility state of the UE, a capability of the UE, a transmission mode of the device-to-device communication, a received indication from the other UE, or a combination thereof. The UE may transmit, to the other UE, data using an MCS selected based at least in part on the MCS configuration. Numerous other aspects are provided.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus communicates with a second apparatus, including transmitting or receiving a first transmission. The apparatus receives information about the second UE from a sensor at the first UE and/or from a BSM. The apparatus determines whether the first apparatus and the second apparatus are in a LOS condition based on a correlation of the information with one or more of a channel estimation, PMI feedback, or RI feedback. The apparatus may adapt a transmission parameter for a second transmission based on a predicted location of the first apparatus or the second apparatus. The transmission parameter may include at least one of a modulation, a code rate, a DMRS density, a precoder, a CSI-RS transmission periodicity or a feedback rate.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support a sensing charging subscription. In a first aspect, a method of wireless communication includes receiving first location information associated with a first mobile entity. The method also includes transmitting an alert based on the first location information and path information configured to model multiple paths associated with an intersection region. The multiple paths include a first path that is curved. The path information defines multiple line segments to model the first path. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for warning pedestrians, for example, of potential collisions with vehicles. The techniques may be considered a hybrid approach to reaching a pedestrian, in that it may employ a combination of interfaces (e.g., the radio interface between the pedestrian UE and the radio access network as well as a sidelink interface between the pedestrian UE and vehicle UE).

Abstract: A user equipment (UE) may communicate with one or more other UEs using multiple transmissions in a device-to-device (D2D) communications deployment. A number of UEs may be configured with D2D resources, and a transmitting UE may identify available D2D resources from the configured resources. The transmitting UE may identify a resource for a first transmission of a D2D transmission from the available D2D resources, and may identify a second resource for a second transmission of the D2D transmission. The second transmission may be a blind HARQ transmission that may be transmitted to enhance the likelihood that one or more receiving UEs successfully receive the transmission. In some examples, the second resource may be identified based on other available resources within an predetermined time window around the first transmission.

Abstract: Aspects of the present disclosure provide synchronization techniques for user equipment (UEs) that may be otherwise unable to support sidelink communication a synchronized UE and may have also lost global navigation satellite system (GNSS) and/or Evolved Node Base Stations (eNBs) as a synchronization source. In such instance, the unsynchronized UE may utilize reference signals (RS) from the data packets received from other UEs to track the timing and perform autonomous timing adjustments based thereon for synchronized packet transmission or reception.
