    Abstract: Apparatuses, systems, and methods for performing downlink signal reception with antenna panel switching in a wireless communication system. A cellular base station may receive an indication of an antenna panel activation delay from a wireless device. The cellular base station may select a scheduling offset for a transmission to the wireless device based at least in part on the antenna panel activation delay. The scheduling offset may be selected to be at least the length of the antenna panel activation delay if it is expected that the wireless device may perform antenna panel activation to receive the transmission. The cellular base station may schedule the transmission to the wireless device using the selected scheduling offset, and may perform the transmission to the wireless device at the selected scheduling offset after scheduling the transmission to the wireless device.

    Abstract: Apparatuses, systems, and methods for enhancing non-PMI based CSI reporting for NC-JT in multi-TRP operations, including addressing channel CRI reporting, CQI reporting, RI reporting, and CSI processing complexity and timeline in NC-JT multi-TRP operations. For example, a UE may receive, from a base station, a configuration for a first set of CSI-RS resources for a first TRP (associated with single TRP operation), a second set of CSI-RS resources for a second TRP (associated with single TRP operation), and a third set of pairs of CSI-RS resources for the first TRP and second TRP (associated with multi-TRP operation). The UE may report, to the base station, a CRI report indicating whether the UE prefers single TRP operation from the first TRP or the second TRP, or multi-TRP operation from the first TRP and the second TRP. The CRI report may be based on the configuration.

    Abstract: Techniques are disclosed relating to handling preemptive data services in cellular wireless transmissions. In some embodiments, a device receives a first downlink control information (DCI) message on resources in a first frequency band, where the first DCI message indicates resources for a physical uplink shared channel (PUSCH) transmission. In some embodiments, the device monitors a downlink control channel on a second frequency band, disjoint from the first frequency band. In some embodiments, subsequent to reception of the first DCI message, the detects an indicator in the downlink control channel and reduces the PUSCH transmission in response to the detection.

    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.
