  • Publication number: 20240427759
    Abstract: A node switchover method is provided, including: A source database nod executes a first query command. Then, the source database node sends target data to a destination database node, where the target data is data for executing a second query command in an execution result of the first query command. Next, the destination database node executes the second query command by using the target data. In the method, some complex operations implemented for node switchover sink to a database node, so that a routing node at which middleware is located does not need to identify a query statement, record a transaction state in real time, or cache a large quantity of query commands that change operation context. This avoids consuming more processor and memory resources of the routing node, reduces costs and overheads of the routing node, and ensures service performance.

  • Publication number: 20240414039
    Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K x a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

  • Patent number: 12167409
    Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of physical downlink control channel (PDCCH) monitoring in different search spaces sets independently from one another in order to manage different services optimally. A processor of the network device can be configured to receive physical downlink control channel (PDCCH) candidates of a PDCCH in a slot for channel estimation across search spaces of the slot. Different priorities can be determined among the PDCCH candidates in the slot based on a priority rule. Then a number of PDCCH candidates can be skipped/dropped from monitoring based on the different priorities of the PDCCH candidates to ensure that a threshold level of blind decoding operations across a plurality of slots of the PDCCH is being satisfied. The UE can monitor a portion of the PDCCH candidates while concurrently skipping another.

The antibody-drug conjugate is formed by means of site-directed conjugation on the basis of an N-glycosylation site of an Fc region of an antibody. The method comprises: (1) providing a donor containing an oxazoline oligosaccharide, an antibody containing a GlcNAc motif, and an immobilized endoglycosidase having a glycoside transfer activity; and (2) covalently linking the activated donor containing the oxazoline oligosaccharide to the antibody containing the GlcNAc motif by means of the catalytic action of the endoglycosidase; therefore, one-step conjugation is realized. The present invention also relates to an endoglycosidase fusion protein, which comprises a covalently linked endoglycosidase, a Halo tag, and/or a His tag.
