Abstract: Methods, systems, and devices are describe for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.

Abstract: Certain aspects of the present disclosure are directed to a method for wireless communication by a network entity. The method generally includes generating a configuration message for a user-equipment (UE) to perform one or more reference signal (RS) measurements on one or more resources of a sidelink channel, transmitting the measurement configuration message, receiving a measurement report indicating results of the one or more RS measurements, and transmitting a scheduling message indicating resources for sidelink transmission on the sidelink channel.

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: The present disclosure addresses selection of a modulation and coding scheme (MCS) for control information multiplexed on a data channel. A spectral efficiency associated with control information may be derived as a function of a spectral efficiency associated with data. A modulation order and/or code rate may be selected that is suitable for the spectral efficiency associated with the data. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to determine a first MCS for control information based on spectral efficiency associated with transmission of data, and further configured to transmit the control information with the first MCS, the control information being multiplexed with data.

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: In an embodiment, a UE identifies a pool of resources where transmission of sidelink synchronization signals is permitted, the pool of resources including at least UE-specific resources, and transmits a sidelink synchronization signal to one or more peer sidelink UEs based on a subset of the pool of resources. In another embodiment, a UE transmits a synchronization request message to at least one peer sidelink UE, and receives at least one sidelink synchronization signal from the at least one peer sidelink UE in response to the transmission of the synchronization request message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, in a first time slot, a set of resources to use for transmission to another UE; evaluate, in a second time slot, whether one or more resources of the set of resources is available; and transmit, based on the one or more resources of the set of resources being available, information to the other UE in a third time slot and using the set of resources, or reselect, based on the one or more resources of the set of resources being unavailable, another resource for transmission of the information to the other UE. Numerous other aspects are provided.

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).
