Abstract: Methods, systems, and devices for wireless communications are described to support resource block (RB) grid alignment at user equipments (UE) in sidelink communications. In a first example, communicating UEs may support different RB grids and a receiving UE may attempt multiple decoding hypotheses for receiving a sidelink control channel from a transmitting UE, where each hypothesis may correspond to a different RB grid. In a second example, an RB grid for a sidelink control channel may be common, or aligned, for a transmitting UE and a receiving UE, such that the receiving UE may receive the sidelink control channel using the common RB grid. In a third example, demodulation reference signals (DMRSs) and resource element (RE) rate matching for a sidelink control channel may be common, or aligned, for a transmitting UE and a receiving UE, such that the receiving UE may receive the control channel using the aligned DMRSs.

Abstract: This disclosure provides systems, methods and apparatuses for indicating sidelink processes for sidelink feedback. A second user equipment (UE) may request hybrid automatic repeat request (HARQ) responses from a first UE for a particular set of sidelink processes over a physical sidelink feedback channel. To indicate multiple sidelink processes, the second UE may indicate, in sidelink control information, a window of sidelink processes. The window may be a sliding window that starts with a starting sidelink process and extends through other sidelink processes. The second UE may transmit data for the sidelink processes in the sliding window and receive feedback for the indicated sidelink processes. In some aspects, the first UE may select, in coordination with the second UE, the sidelink processes for which feedback is to be provided.

Abstract: An animal irradiation system includes a radioactive source and an irradiation fixing apparatus having irradiated bodies. The radioactive source includes a beam outlet having a first central axis. Radioactive rays generated by the radioactive source exit from the beam outlet and irradiate the irradiated bodies.

Abstract: Techniques for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling sidelink transmissions in one or more sets of multiple transmission time intervals (TTIs) over a shared spectrum. The UE may perform a listen-before-talk (LBT) for one or more of the TTIs in the one or more sets of multiple TTIs, and the UE may transmit, to a base station, an indication of results of the LBT performed for the one or more TTIs. Because the UE may provide the results of the LBT to the base station, the base station may be able to schedule sidelink transmissions from the UE based on the results of the LBT. As such, the UE may experience increased throughput in sidelink communications since the scheduling at the base station may be improved.
