Abstract: The present disclosure relates to the preparation of a highly pure cannabidiol compound by a novel synthesis route. The cannabidiol compound can be prepared by an acid-catalyzed reaction of a di-halo olivetol with menthadienol, followed by two crystallization steps. The highly pure cannabidiol compound is produced in high yield, stereospecificity, or both, and shows exceedingly low levels of ?-9-tetrahydrocannabinol at the time of preparation and after storage.

Abstract: A wireless device receives an activation command indicating activation of a transmission configuration indicator (TCI) state for a first control resource set (coreset) with a coreset pool index of a plurality of coreset pool indexes of a cell. The wireless device receives, via a second coreset with the coreset pool index, downlink control information (DCI) indicating transmission of an aperiodic sounding reference signal (SRS) via the cell. In response to the receiving the DCI via the second coreset with the coreset pool index, the wireless device transmits the aperiodic SRS with a transmission parameter determined based on the TCI state associated with the coreset pool index.
