Problems solved by technology

Regardless of the amplifying and forwarding cooperative mode or the decoding and forwarding cooperative mode, the cooperative node needs to process the data from the source node, which makes the cooperative node consume more power.
In addition, if the decoding and forwarding cooperation mode is adopted, that is, the cooperative node decodes the information from the source node, there is a data security risk

Abstract

The invention discloses a cooperative communication method and a communication device.The cooperative communication method comprises the steps that a target cooperative node is determined, beam forming parameters are sent to the target cooperative node, and data signals are sent to a destination node, the beamforming parameter comprises a target phase of the RIS of the target cooperative node, and the data signal is reflected to the destination node by the target cooperative node. The RIS can directly reflect the incident wireless wave, namely, directly reflect the data signal from the source node to the destination node, and does not need to amplify and decode the data to be sent, so that the power consumption can be reduced, and the safety of the data can be protected. Meanwhile, compared with two stages of a traditional cooperative communication process, as the RIS can directly reflect incident wireless waves and reflect data signals to a destination node, the RIS can be considered as one stage. The system capacity can be improved.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of the Chinese patent application with the application number 202010482268.9 and the application title "a cooperative communication method, sending device, and receiving device" filed with the China Patent Office on May 29, 2020, the entire contents of which are hereby incorporated by reference In this application. technical field [0003] The present application relates to the technical field of communication, and in particular to a cooperative communication method and a communication device. Background technique [0004] In order to improve the quality of the wireless transmission link and increase the coverage, the cooperative communication technology is introduced. That is, a connection is established with the core network through the backhaul link of the coordination node. [0005] The traditional cooperative communication process can be roughly divided into two stages, one ...
