Provided are a heterocyclic carboxylic acid amide ligand and applications thereof in a copper catalyzed coupling reaction. Specifically, provided are uses of a compound represented by formula (I), definitions of radical groups being described in the specifications. The compound represented by formula (I) can be used as the ligand in the copper catalyzed coupling reaction of the aryl halogeno substitute, and is used or catalyzing the coupling reaction for forming the aryl halogeno substitute having C&#x2014;N, C&#x2014;O, C&#x2014;S and other bonds.

An information processing method and apparatus relate to the field of mobile communications technologies, which are used to resolve a technical problem that no better network planning method is available. A user target throughput (UTT) for a user terminal and a grid throughput ability (GTA) of a grid in which the user terminal is located are determined such that whether a GAP area exists in the grid is determined. This determining manner not only considers user experience, but also makes reference to real service features of a network. Conducting network planning in this manner can make network planning more appropriate and make user experience better.
