Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes receiving broadcast information from a base station that identifies types of resources for vehicle-based sidelink communications that are supported by the base station and transmitting a request to the base station for resource scheduling information to perform a vehicle-based sidelink communication based on the broadcast information. In some cases, the request includes an indication of a type of resources for the vehicle-based sidelink communication supported by the base station and a quality of service (QoS) metric associated with the vehicle-based sidelink communication. In some cases, the method further includes receiving, in response to the request, a response from the base station that comprises the resource scheduling information to perform the vehicle-based sidelink communication.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) performs a limited beam sweep of one or more transmit beams on a second frequency band in an estimated direction from the first UE to the second UE, wherein the estimated direction is based on one or more parameters received over a previously established signaling radio bearer (SRB) on a first frequency band and/or a device-to-device discovery procedure performed on the first frequency band, receives, over the SRB, a confirmation that a data radio bearer (DRB) has been established on the second frequency band with at least one transmit beam of the one or more transmit beams, and sends, to the second UE, a data flow over the DRB on the second frequency band using the at least one transmit beam.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), e.g., a vehicle in a group of platooning vehicles configured for wireless communications, may identify a travel direction of the group of platooning vehicles. The UE may identify a set of time-frequency radio resources allocated to the travel direction. The UE may perform inter-vehicle communications with one or more neighboring vehicles of the group of platooning vehicles using the set of time-frequency radio resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may initiate a radio resource control (RRC) layer signaling procedure between the UE and a target UE, include an upper layer signaling message in an RRC message based in part on the RRC layer signaling procedure, and transmit the RRC message including the upper layer signaling message to the target UE. Alternatively, upper layer signaling messages may be transmitted separately before or after the RRC layer signaling procedure.

Abstract: According to one aspect of the disclosure, a first method, a first computer-readable medium, and a first apparatus are provided. The first apparatus may be a UE. The first apparatus may receive, from a base station, a first grant associated with a first set of resource available to the first apparatus for transmission on a first sidelink channel. The first apparatus may determine whether to request, from the base station, a second grant associated with a second set of resources available to the first apparatus for transmission on the first sidelink channel. The first apparatus may send, to the base station, a request for the second grant when determining to request the second grant. Further, the first apparatus may send information on the first sidelink channel based on the first grant when determining not to request the second grant.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may be communicating via a relay wireless communication link. The communicating may include communications using a plurality of bearers. The transmitting device may identify a packet for transmission on the relay wireless communication link belonging to a first bearer. The first bearer may have an associated quality of service (QoS) parameter set. The transmitting device may configured a header of the packet that is processed by a relay wireless device to convey an indication of the QoS parameter set. The transmitting device may transmit the packet including the configured header on the relay wireless communication link and according to the QoS parameter set.

Abstract: A transmitting UE may in a device-to-device (D2D) communication may identify a demodulation reference signal (DMRS) sequence for a D2D transmission based at least in part on a subset of bits of a sidelink control information (SCI) transmission. The subset of bits of the SCI transmission may be selected such that the bits have sufficient variability to reduce the likelihood that multiple UEs may use the same DMRS sequence. The subset of bits of the SCI transmission may be all or a portion of a cyclic redundancy check (CRC) for the SCI.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems support beamforming to improve the reliability of transmissions from a transmitting device to a receiving device. In some cases, a wireless device broadcasts information using beamforming. In such cases, in order to limit the overhead and power consumption associated with the broadcast, the wireless device utilizes the techniques described herein for broadcasting information using beamforming. In particular, rather than broadcasting large amounts of data in a beam-sweep, a wireless device broadcasts a relatively lightweight signal in a beam-sweep to first identify a receiving device and/or a suitable beam for communicating with a receiving device. Once the transmitting device identifies the receiving device and/or the suitable beam, the transmitting device broadcasts the data to be received by the receiving device.

Abstract: Methods, systems, and devices for wireless communication are described that provide for priority-based carrier selection in a system using multiple component carriers (CCs). A mapping may be provided that maps different applications that may be present at a user equipment (UE) to one or more CCs. Each application may have an associated application priority, and each carrier associated with an application may also have an associated CC priority. A UE may select a subset of CCs for a transmission based on the mapping between an application providing a packet for the transmission and the priority associated with each CC. A UE, when receiving transmissions, may identify one or more applications running at the UE and use the mapping to determine a subset of CCs to monitor for transmissions.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided that enable UEs to conserve power while involved in ProSe communication. The apparatus transmits discovery class information for ProSe communication to an A-UE and to an M-UE. The discovery class information may be transmitted from a PF in response to discovery requests. Discovery class rules may be sent from the PF as a part of service authorization. The discovery class information may be transmitted from a ProSe application server as application layer signaling. The A-UE and M-UE may use the discovery class information to select a pool of ProSe resources according to the discovery class information for transmission or monitoring of ProSe communication. The M-UE may use the information to reduce the number of resource pools of resources that are monitored for ProSe communication.
