Abstract

The embodiment of the invention discloses a precoding configuration method, device and system. The precoding configuration method comprises the following steps: generating precoding configuration information, wherein the precoding configuration information is used for configuring the width of a frequency band for performing the same precoding; and transmitting the precoding configuration information. The embodiment of the invention further provides a sending end device, a receiving end device, and a precoding configuration system. According to the precoding configuration method provided in theembodiment of the invention, by generating and sending the precoding configuration information, a receiving end can determine the width of the frequency band for performing the same precoding. Compared with the prior art, the width of the frequency band for performing the same precoding is determined only by the system bandwidth, and the technical scheme provided by the embodiment of the invention can flexibly determine the width of the frequency band for performing the same precoding, and can satisfy the diverse scene demands of a wireless communication system and optimize the system performance for different scenes.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a precoding configuration method, device and system. Background technique [0002] In a Multiple Input Multiple Output (English: Multiple Input Multiple Output; MIMO for short) system, by adopting multi-antenna precoding at the data transmitting end, the system performance can be effectively improved. In order to support the receiving end to demodulate the data, the sending end usually needs to precode the demodulation reference signal (English: DeModulation Reference Signal; DMRS for short), so that the receiving end can channel the precoded equivalent channel. estimate. [0003] In a system based on Orthogonal Frequency Division Multiplexing (English: Orthogonal Frequency Division Multiplexing; OFDM for short), data is transmitted on multiple subcarriers in the frequency domain. In order to avoid consuming too many resources, the DMRS is not transmitted on all ...
