Abstract: The present disclosure provided a blood cell analyzer, a control device and a blood analysis method thereof. In the method, a first reagent is mixed with a sample to obtain a first testing sample, and then a second reagent is mixed with the first testing sample for a further reaction to get a second testing sample for basophil classification and/or HGB measurement. A blood sample may be tested in one reaction cell through time-division multiplexing technology to obtain four groups leukocytes classification result and HGB result by single detection channel. Thus, the structure of the analyzer may be greatly simplified on the premise of guaranteeing the performance of the analyzer, the size and cost of the analyzer may reduce and a performance-price ratio of the analyzer may increase.

Abstract: Aspects of the disclosure provide methods, apparatuses and systems for wireless communication. In some embodiments, a wireless communication system includes processing circuitry. The processing circuitry of the wireless communication system operates based on a first radio access technology. The processing circuitry receives a sidelink control request from a first user equipment that accesses the wireless communication system using the first radio access technology. The sidelink control request requests sidelink control information for a second radio access technology. The processing circuitry then obtains the sidelink control information for the second radio access technology, and provides, via the first radio access technology, the sidelink control information for the second radio access technology, to the first user equipment. The sidelink control information is used to configure a sidelink between the first user equipment and a second user equipment using the second radio access technology.
