    Abstract: In 5G/New Radio (NR), sidelink communication refers to a channel for communications directly between devices, e.g., user equipment (UEs), without use of traditional uplink or downlink communication channels. Sidelink Control Information (SCI) is separated into two stages (i.e., SCI stage 1 and SCI stage 2) before being transmitted to configure a user device. A method for configuring sidelink communications for a wireless device includes: obtaining SCI Stage 2 payload information; attaching and distributing cyclic redundancy check (CRC) information to the payload information; performing encoding and rate matching (RM) on the payload information; scrambling the encoded and rate matched payload information; performing modulation on the scrambled payload information; determining a resource mapping for the modulated payload information, wherein the modulated payload information is aggregated across two or more slots (e.g., using different processing operations for at least two slots); and transmitting the modulated payload information according to the determined resource mapping.

    Abstract: A user equipment (UE) device including an antenna, a memory, a RF circuitry commutatively coupled to the antenna, and a processor configured to perform operations is described. In an exemplary embodiment, the operations include receiving a Radio Resource Control (RRC) release message from a base station, wherein the RRC release message comprises a suspend configuration to transition the UE to an RRC_INACTIVE state. In addition, the operations include entering the RRC_INACTIVE state. The operations include performing, while the UE is in the RRC_INACTIVE state, an initial data transmission without transitioning from the RRC_INACTIVE state to a RRC_CONNECTED state. Additionally, the operations include monitoring a physical downlink control channel (PDCCH) for a UE dedicated scheduling for a transmission or reception of a subsequent data during an active period, while the UE is in the RRC INACTIVE state. Further, the operations include performing the transmission or reception of the subsequent data based on the monitoring of the PDCCH.

    Abstract: A method for wireless communication includes: scheduling, by a wireless station, a first uplink (UL) transmission from a wireless device; determining, by the wireless station, a need for a higher priority uplink transmission that uses resources overlapping with the first UL transmission; determining, by the wireless station, a reference region, within which a UL cancellation indication (CI) is to be applied; determining, by the wireless station, a set of UL resources in the reference region for cancellation, wherein at least a subset of the UL resources in the reference region are interlaced; sending, via a downlink control channel, indication of the determined set of UL resources for cancellation (e.g., by indicating particular interlaces and/or particular Physical Resource Blocks within such interlaces that are to be canceled); and receiving, at the wireless station, the higher priority uplink transmission via at least a subset of the determined set of cancelled UL resources.

    Abstract: Disclosed are embodiments for a request and response signaling between first and second user equipment (UE) via a PC5 link for configuring inter-UE coordination. In some embodiments, request signaling entails a first UE identifying a transmit resource pool of the first UE to be sensed or evaluated by the second UE; instructing the second UE to report information indicating a quantity of resources; and instructing the second UE to evaluate the resources to be reported. In other embodiments, response signaling entails a first UE receiving from the second UE a request signal for inter-UE coordination; indicating a set of one or more resources, in which the set is indicated as corresponding to whitelist, blacklist, or collision list; and providing a validity time for resources indicated.
