  • Patent number: 9204456
    Abstract: A method of controlling a load at a wireless communication base station includes determining an indication of a maximum path loss between the base station and any high speed data users currently in a cell served by the base station. A target loading limit for the cell is set based upon the determined indication of the maximum path loss. In disclosed examples, the indication of the maximum path loss corresponds to a distance between a high speed user and a base station. Another factor considered in disclosed examples includes the data rate of such a high speed user.

  • Publication number: 20110160413
    Abstract: Provided are a novel transition metal complex where a monocyclopentadienyl ligand to which an amido group is introduced is coordinated, a catalyst composition including the same, and an olefin polymer using the catalyst composition. The transition metal complex has a pentagon ring structure having an amido group connected by a phenylene bridge in which a stable bond is formed in the vicinity of a metal site, and thus, a sterically hindered monomer can easily approach the transition metal complex. By using a catalyst composition including the transition metal complex, a linear low density polyolefin copolymer having a high molecular weight and a very low density polyolefin copolymer having a density of 0.910 g/cc or less can be produced in a polymerization of monomers having large steric hindrance. Further, the reactivity for the olefin monomer having large steric hindrance is excellent.
