1. A method implemented at a network node, comprising:
obtaining channel information of a terminal device;
determining a self-correlation factor of the terminal device according to the channel information;
determining main lobe width according to a relationship between the self-correlation factor and main lobe width;
determining a weight vector on at least one transmitting antenna according to the determined main lobe width; and
transmitting a message using the weight vector on the at least one transmitting antenna, to the terminal device, wherein determining the weight vector on the at least one transmitting antenna according to the determined main lobe width, comprises:
comparing the determined main lobe width with an initial main lobe width to obtain a difference between the determined main lobe width and an initial main lobe width;
obtaining a scale-vector corresponding to the difference according to a relationship between differences and scale-vectors; and
determining the weight vector on the at least one transmitting antenna according to the scale-vector and an initial weight vector corresponding to the initial main lobe width.
