Abstract: A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.

A universal representation to be used for executing one or more tasks, working on data with one or more signal modalities and comprising modal fusions signals at various levels is learned from a dataset that is targeted user or object agnostic. This universal representation is combined with a second stage task specific representation that is learned on-the-device using data from the particular user without sending the data to the cloud.

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. 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 request to a base station for resources to use to perform the vehicle-based sidelink communications, the request comprising an indication of the profile, a reliability metric associated with the profile, and an identifier that identifies the set of carrier frequencies. The UE may receive one or more grants from the base station for semi-persistent scheduling resources allocated on the set of carrier frequencies in response to the request.

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: Techniques are described for performing beam sweep procedures as part of a device discovery procedure. A transmitting device (e.g., user equipment (UE) or base station) may generate a discovery preamble that is configured to indicate that a discovery message will be transmitted. The discovery preamble may be a smaller message (e.g., less bits) than the discovery message and thus may use fewer resources when it is being communicated. The transmitting device may transmit a plurality of signals that include a discovery preamble as part of beam sweep procedure. Once the transmitting device identifies a receiving device, the transmitting device may broadcast the discovery message. The discovery preamble may include a variety of different types of information including information relating to an identifier for the transmitting device, a discovery mode of the transmitting device, beam configurations, communication resources, beam sweep indexes, or a combination thereof.

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.

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.

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: Methods, systems, and devices for wireless communications are described. A UE may identify a shortened transmission time interval (TTI) to be used for priority communications with a vehicle having a first traffic priority level, the shortened TTI having a duration that is less than that of other TTIs used in other communications with the vehicle having a second traffic priority level less than the first traffic priority level. The UE may transmit a request-to-send (RTS) message during the shortened TTI, the RTS message indicating an identifier and a configuration for the priority communications during the shortened TTI. The UE may receive a clear-to-send (CTS) message from one or more wireless devices participating in the priority communications, the CTS message indicating a sequence associating the CTS message with the RTS message. The UE may perform the priority communications with the wireless devices from which the CTS messages were received.

Abstract: Described are methods for interference detection and management in a millimeter wave communications system. A V2X communications system may support interference management procedures that comprise scheduling a system wide training interval in a transmission timeslot, suspending traffic transmissions on a link in the communications system during the training interval to perform training on the link, and resuming traffic transmissions on the link if interference is not detected during the training interval. Interference management procedures may also include receiving at a node, unique parameters transmitted from another node in a communication system during a discovery stage, determining whether interference will occur at the node based on the received unique parameters, and suspending transmissions to and from the node if it is determined interference will occur at the node.
