  • Publication number: 20210266884
    Abstract: A User Equipment (UE) monitors a set of Physical Downlink Control Channel (PDCCH) candidates for control information received from a base station at subframe k. The set of PDCCH candidates to monitor are defined in terms of search spaces. The UE monitors a UE-specific search space, among the search spaces, at each of aggregation levels (L) of 1, 2, 4 and 8 control channel elements (CCEs), the CCE being a resource unit comprising a specific number of resource elements and used for transmission of the control information. The L CCEs correspond to a first PDCCH candidate among the set of PDCCH candidates of the search space at a subframe k are located at positions given by: L*{(Yk)mod(floor(C))}+i, wherein i=0, . . . , L?1, where Yk is defined by: Yk=(A*Yk?1+B) mod D. The variable C is determined based on the number of CCEs (NCCE) divided by the aggregation level (L), and A, B, and D are predetermined constant values predetermined regardless of the aggregation levels L.

  • Patent number: 11097240
    Abstract: The present invention relates to a pickering emulsion composition using polyimide particles and a method for preparing the same. The pickering emulsion stabilized by the polyimide particles according to the present invention has a very stable dispersed phase and does not cause flocculation, creaming, coalescence and phase separation even after a long time, and has an advantage of being capable of forming both an oil-in-water type emulsion and a water-in-oil type emulsion. Further, the polyimide particles used in the present invention can be synthesized in a simple manner and have partial wettability without the surface treatment and pH control so that they can be easily used for the emulsion stabilization.
