Abstract

The invention discloses a wave beam forming method of a next-generation broadcast television net, a system and an interacting base station, wherein the wave beam forming method comprises the following steps: the interacting base station receives channel information from a terminal and position information of the terminal; and the interacting base station sends the channel information and the position information of the terminal to a broadcast base station, so that the broadcast base station adjusts antenna parameters according to the channel information and the position information of the terminal. In the wave beam forming method, the power of a transmitter can be reduced and the receiving quality can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a beamforming method and system of a Next Generation Broadcasting network (NGB for short), and an interactive base station. Background technique [0002] As an important part of my country's information infrastructure, the radio and television network is the most popular information tool and the most convenient information carrier to reach thousands of households. [0003] The traditional radio and television network, because it is a one-way broadcast network, has no reverse information transmission channel. Therefore, various advantages brought by modern digital wireless technology: such as the best reception of signals, the improvement of spectrum efficiency, and the increase of system capacity etc., can not be applied. [0004] With the acceleration of the process of "Next Generation Broadcasting Network (NGB)" and "Three Networks Convergence", people have more and more cha...
