Abstract

The invention discloses a beam forming transmission method and network equipment, which are used for solving the defects of limited flexibility and limited performance of the method for improving channel estimation quality in the prior art; the method comprises the following steps that: a network side determines configuration information of a PRB bundling parameter, wherein the time domain configuration information in the configuration information is configurable; the network side transmits the configuration information to a terminal, so that after the terminal receives the configuration information, channel estimation and demodulation are performed by using a precoding mode corresponding to the configuration information.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a beamforming transmission method and network equipment. Background technique [0002] With the continuous development of science and technology, wireless access technologies such as LTE (Long Term Evolution, long-term evolution), LTE-A (LTE-Advanced, evolution of LTE) and the like have been widely used. [0003] In the current LTE system, in order to improve the quality of channel estimation, PRB bundling technology (Physical Resource Block bundling, physical resource block bundling technology) is usually used, thereby limiting the signal in several consecutive PRB (Physical Resource Block, physical resource block ) to maintain the precoding mode without mutation. The implementation process is as follows: first, the network side determines the size of the PRG (Precoding Resource Block Group, Precoding Resource Block Group) according to the system bandwidth, and...
