Abstract: A preparation method of a rhodium octanoate dimer includes the following steps: (1) mixing RhCl3 with an alkali metal octanoate uniformly to get a first solution; (2) adding a reductant into the first solution obtained from step (1), and heating for reflux reaction to get a second solution; (3) adding the second solution obtained from step (2) into deionized water while hot, continuing to stir, and performing a suction filtration to get a crude product; and (4) performing a primary washing, a secondary washing, a filtration, and a drying on the crude product obtained from step (3) to get a rhodium octanoate dimer as a green solid.

Abstract: A control information sending/receiving method and device are provided, to implement indicating a time-frequency location of a control channel to a terminal device in a 5G NR system or a future evolved LTE system. The method includes: receiving, by a terminal device, broadcast information; determining, from at least two predefined time-domain locations, a time-domain location of a broadcast channel carrying the broadcast information; determining a time-domain location of a control channel based on the time-domain location of the broadcast channel; and performing control channel detection in the determined time-domain location of the control channel.
