Abstract: A method performed by an apparatus is described. The method includes receiving a first set of object data corresponding to a first journey. The method also includes receiving a second set of object data corresponding to a second journey. The method further includes determining a similarity metric between the first set of object data and the second set of object data. The similarity metric indicates a distance between the first set of object data and the second set of object data for at least one object. The method additionally includes clustering the first set of object data and the second set of object data for the at least one object based on the similarity metric to produce at least one object cluster. The method also includes producing map data based on the at least one object cluster.

Abstract: Methods, apparatuses, systems, and devices are described for wireless communication. In one method, a control format indicator value for a frame may be received over a physical carrier in a shared spectrum. Based on the control format indicator value, a number of subframes of the frame to be used by a base station for downlink transmissions over the physical carrier may be determined. The control format indicator value may indicate an end of transmission, if data is to be transmitted during the frame, a number of subframes to be used for transmission, or whether the current subframe is the final subframe used for transmission. In some cases, a user equipment (UE) may use the control format indicator value to determine a sleep schedule. Further, ACK/NACK transmissions by a UE may be scheduled based on the control format indicator value.

Abstract: The present disclosure, for example, relates to one or more techniques for scaling the bandwidth of a carrier. Available sub-channels of an unlicensed radio frequency spectrum band may be determined, and the available sub-channels may be included in the carrier. The available sub-channels may be adjacent or non-adjacent sub-channels. The bandwidth of the carrier may be determined according to which sub-channels are included in the carrier. In this way, the bandwidth of the carrier may be scaled according to the available sub-channels in the unlicensed radio frequency spectrum band.

Abstract: The present disclosure provides methods and apparatuses for multi-carrier transmissions over adjacent channels that reduce self-jamming due to asymmetric interference. In an aspect, a large bandwidth load-base equipment (LBE) carrier may be provided such that CCA is performed jointly over the entire bandwidth. In another aspect, additional CCA timeslots may be used to synchronize the two carriers. In a further aspect, an extended CCA may be performed on a primary unlicensed carrier while a simple CCA may be performed on a secondary unlicensed carrier. In yet another aspect, LBE may be deployed on some carriers while frame-base equipment (FBE) may be deployed on other carriers.

Abstract: A method performed by an apparatus is described. The method includes receiving map data that is based on first image data, second image data, and a similarity metric. The first image data can be received from a first vehicle and represent an object. The second image data can be received from a second vehicle and represent the object. The similarity metric can be associated with the object represented in the first image data and the object represented in the second image data. The method can also include storing, by a vehicle, the received map data and localizing the vehicle based on the stored map data.

Abstract: Various aspects related to techniques for harmonization between common reference signal (CRS) and demodulation reference signal (DM-RS) based transmission modes (TMs) in unlicensed spectrum are described. In one aspect, a downlink/uplink (DL/UL) subframe configuration may be signaled for each subframe. Information provided by the DL/UL subframe configuration may indicate whether the respective downlink subframe is a single-frequency network (MBSFN) subframe (associated with DM-RS-based TM) or a non-MBSFN subframe (associated with CRS-based TM). In another aspect, periodic as well as aperiodic channel state information (CSI) reporting requests may be supported. In yet another aspect, discontinued reception (DRX) wake ups for unlicensed carriers may be explicitly or implicitly indicated to a user equipment (UE) via a carrier in a licensed spectrum.

Abstract: A method and apparatus for uplink transmission by a user equipment (UE) includes receiving a first assignment for one or more beacon signals. The first assignment includes a first resource assignment and a first interlace assignment. The UE may determine that a size of a payload of an uplink transmission is less than a threshold. The UE may transmit the one or more beacon signals according to the first assignment in response to the determination. The one or more beacon signals increase bandwidth occupancy by the UE over a contention-based spectrum. Additionally, the UE may receive a second assignment for the payload of the uplink transmission. The second assignment includes a second resource assignment and a second interlace assignment. The UE may transmit the payload of the uplink transmission according to the second resource assignment on the second interlace assignment.
