    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 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.
