Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may broadcast a discovery preamble to identify a receiving device or to identify a suitable beam for communicating with a receiving device prior to broadcasting a discovery message to the receiving device. In such systems, the wireless device may use the techniques described herein to generate the discovery preamble and to reduce interference between discovery preamble transmissions and avoid data loss. In one example, a wireless device may append a cyclic prefix (CP) to a discovery preamble with a suitable length to protect the discovery preamble from interference from another transmission. In another example, the wireless device may generate a cyclically periodic signal including multiple copies of the discovery preamble so a receiving device may be able to receive a portion of the signal and identify the discovery preamble.

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: Aspects directed towards a network-assisted sidelink scheduling operation are disclosed. In one example, a scheduled entity receives a grant of resources from a scheduling entity operating according to a legacy radio access technology (RAT), and translates the grant of resources from a legacy configuration of resources to a non-legacy configuration of resources. The scheduled entity then performs a sidelink communication via the non-legacy configuration of resources. In another example, a scheduling entity operating according to a legacy RAT transmits a system information block (SIB) to a scheduled entity indicating that the scheduling entity can allocate non-legacy resources. The scheduling entity then receives a request for resources from the scheduled entity that corresponds to a non-legacy sidelink communication, and provides a grant of resources to the scheduled entity that includes a non-legacy-specific frequency for transmitting the non-legacy sidelink communication.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, some user equipment (UEs) may be configured for sidelink communications using a first radio access technology (RAT) (e.g., via a cellular network) and other wireless devices may be configured for sidelink communications using a second RAT (e.g., via a wireless local area network (WLAN)). In order to mitigate interference between communications using the first and second RAT, when a first UE is scheduled to transmit or receive a data transmission on a set of resources using the first RAT, the first UE may transmit a message using the second RAT indicating that the data transmission is to occur on the set of resources. Accordingly, the second device may receive the message and determine to refrain from communicating on the set of resources.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a first wireless communication device may transmit, to a relay node, a first predicted motion of a first vehicle including the first wireless communication device having a first established communication channel with the relay node. The first wireless communication device may receive an indication that the first predicted motion will trigger a communication condition for the first vehicle and a second wireless communication device having a second established communication channel with the relay node, the indication including reserved resources for a third communication channel between the first wireless communication device and the second wireless communication device. The first wireless communication device may communicate with the second wireless communication device using the reserved resources for a third communication channel without performing a random access procedure with the second wireless communication device.

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 communications are described. A user equipment (UE) may determine that a profile for vehicle-based sidelink communications supports packet duplication using a set of carrier frequencies. The UE may transmit a message to a base station that identifies the profile and the set of carrier frequencies. The UE may receive a configuration message from the base station that identifies a packet duplication configuration. The UE may transmit, based on the packet duplication configuration, a request to the base station for resources to perform the vehicle-based sidelink communications, the request comprising one or more buffer status report (BSRs), wherein each BSR identifies a carrier frequency for the BSR and a logical channel group identifier that identifies the BSR as being for packet duplication.

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.
