Abstract: Various embodiments of the present disclosure may be used to determine how activation downlink control information (DCI), release DCI, and dynamic retransmission DCI are distinguished for DCI formats 3_0/3_1 for Mode-1 sidelink resource allocation. Furthermore, in case of asynchronous downlink (DL) and sidelink (SL) carriers, embodiments of the present disclosure may be used to determine how a user equipment (UE) determines transmission slots with respect to system frame number (SFN) or direct frame number (DFN) when activated with Type 1 configured scheduling.

Abstract: An apparatus and system for inter-UE coordination feedback for sidelink communications are described. In particular, inter-UE coordination feedback signaling for reliable sidelink communication including transmitter-based resource allocation and signaling of conflicts, prioritization of the inter-UE coordination feedback, and timing of the inter-UE coordination feedback are described. Sidelink hybrid acknowledgment request (HARQ) acknowledgment/negative acknowledgment (ACK/NACK) or NACK only signaling is prioritized over a half-duplex (HD) or co-channel collision (CC) feedback indication, and uplink transmissions are prioritized over sidelink transmissions. In response to detection of a conflict, the inter-UE coordination feedback is transmitted relative to the slot where the HD or CC event occurs or relative to the slot where reservation of the resources for the sidelink transmissions.

Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for New Radio (NR) vehicle-to-everything (V2X) sidelink communication. The processing circuitry is to determine a set of candidate resources of the UE from a sidelink resource pool, the sidelink resource divided into multiple time slots, frequency channels, and frequency sub-channels. Sidelink control information (SCI) is encoded for transmission to a second UE via a physical sidelink control channel (PSCCH). The SCI indicates a plurality of transmission resources of the set of candidate resources. A transport block is mapped across the plurality of transmission resources. A physical sidelink shared channel (PSSCH) is encoded for transmission to the second UE using the plurality of transmission resources, the PSSCH encoded to include the mapped transport block.

Abstract: A computer-readable storage medium stores instructions to configure a UE for sidelink operation in a 5G NR network, and to cause the UE to perform operations including decoding a first sidelink transmission received from a second UE. The first sidelink transmission includes a first resource reservation for a subsequent sidelink transmission by the second UE. A second sidelink transmission received from a third UE is decoded. The second sidelink transmission includes a second resource reservation for a subsequent sidelink transmission by the third UE. A co-channel collision is detected based on the first resource reservation and the second resource reservation being in a same sidelink slot. A feedback message is encoded for transmission to the second UE and the third UE. The feedback message indicates the co-channel collision.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for jointly performing text detection and layout analysis. In one aspect, a method comprises processing the image and a set of object queries to generate an encoded representation of the image and an encoded representation of the set of object queries; processing the encoded representation of the image and the encoded representation of the set of object queries to generate a set of text detection masks; processing the encoded representation of the set of object queries to generate layout relevance measures; processing the encoded representation of the set of object queries to generate textness scores for the text detection masks; generating a text detection output that defines respective areas of the image that include text items; and generating a layout analysis output that defines clusters of respective areas of the image identified by the text detection masks.
