The disclosure provides a multi-layer beam forming method. The method includes: according to an obtained transmitting weight value of each space channel layer, obtaining a signal-to-noise ratio of a data stream, arriving at a receiving side, of each layer; according the obtained signal-to-noise ratio of the data stream, arriving at the receiving side, of each layer, determining a data stream which is able to be transmitted; performing beam forming for the data stream which is able to be transmitted and transmitting the data stream subjected to the beam forming to the receiving side. The disclosure further provides User Equipment (UE) for implementing multi-layer beam forming. Only a data stream, which can be decoded by a receiving side, of each layer is transmitted, thereby utilizing channel capacity to the most extent while adequately and reasonably utilizing space channel resources. |

1. A multi-layer beam forming method, comprising:
according to an obtained transmitting weight value of each space channel layer, obtaining a signal-to-noise ratio of a data stream, arriving at a receiving side, of each space channel layer; according the obtained signal-to-noise ratio of the data stream, arriving at the receiving side, of each space channel layer, determining a data stream which is able to be transmitted; performing beam forming for the data stream which is able to be transmitted and transmitting the data stream subjected to the beam forming to the receiving side; wherein a process of determining the data stream which is able to be transmitted according to the obtained signal-to-noise ratio of the data stream, arriving at the receiving side, of each space channel layer comprises: comparing the obtained signal-to-noise ratio of the data stream, arriving at the receiving side, of each space channel layer and a preconfigured signal-to-noise ratio threshold, and determining that a data stream, whose signal-to-noise ratio when the data stream arrives at the receiving side is greater than the signal-to-noise ratio threshold, of each space channel layer is the data stream which is able to be transmitted. |
