In a related technology, the precoding of the smart repeater/RIS and the precoding of the base station are jointly designed mainly by an alternate optimization technology. However, a sending method for an assistance communication device implemented based on the alternate optimization technology needs to separately use different algorithms to jointly design the precoding of the smart repeater/RIS and the precoding of the base station, which results in a relatively high complexity and a relatively poor applicability.
The present disclosure provides sending methods and devices for an assistance communication device, communication apparatuses, and storage mediums, to solve the technical problems of the relatively high complexity and poor applicability for the sending method for an assistance communication device in the related technology.
The sending methods and devices for an assistance communication device, storage mediums, and apparatuses provided by the present disclosure will be described in detail below with reference to the accompanying drawings.
In an embodiment of the present disclosure, the assistance communication device may be an RIS array and/or a smart repeater.

Specifically, in an embodiment of the present disclosure, the CSI includes at least one of: a precoding matrix; a PMI (precoding matrix index); an offset phase value; an RSRP (reference signal receiving power); or a direct or indirect identifier of a measurement reference signal, for indicating the measurement reference signal corresponding to the CSI.
In an embodiment of the present disclosure, the offset phase value for the assistance communication device is a difference value between a phase of transceiving signals on a channel (that is, a communication link between the assistance communication device and a terminal device) for the assistance communication device and a phase of transceiving signals on a channel (that is, a communication link between a reference assistance communication device and the terminal device) for the reference assistance communication device. In addition, in an embodiment of the present disclosure, the reference assistance communication device may be any one selected assistance communication device.
In addition, in an embodiment of the present disclosure, the direct or indirect identifier of the measurement reference signal may be used to uniquely indicate the measurement reference signal. The measurement reference signal may be a reference signal transmitted on the communication link between the assistance communication device and the terminal device, and the CSI is obtained by measuring the reference signal. Based on this, the measurement reference signal corresponding to the CSI may be determined by enabling the CSI to include the direct or indirect identifier of the measurement reference signal, and then the assistance communication device for the CSI may be determined.
For example, in an embodiment of the present disclosure, the direct or indirect identifier of the measurement reference signal may be an index of the measurement reference signal. In another embodiment of the present disclosure, the direct or indirect identifier of the measurement reference signal may be an identifier of a resource used by the measurement reference signal.
In addition, in an embodiment of the present disclosure, the sending scheme may include precoding information and/or sending power information. The precoding information may include a PMI and/or incident angle information, and the sending power information may be a sending power coefficient for the communication link between the assistance communication device and the terminal device. It should be noted that in an embodiment of the present disclosure, when there are different types of assistance communication devices, the sending scheme also includes different contents, and the contents will be described in detail in subsequent embodiments.
In addition, it should be noted that in an embodiment of the present disclosure, both the CSI and the sending scheme are determined based on a channel condition of the communication link between the assistance communication device and the terminal device. In addition, based on different channel conditions of communication links between different assistance communication devices and the terminal device, the different assistance communication devices will correspond to different CSIs and sending schemes. In an embodiment of the present disclosure, each of the assistance communication devices obtains the CSI and/or sending scheme for the assistance communication device.
In an embodiment of the present disclosure, the indication information may include CSI and/or a sending scheme; the assistance communication device may include an RIS or a smart repeater, and when there are different indication information or assistance communication devices. There are also different methods for executing precoding for the assistance communication device based on the indication information. This content will be described in detail in subsequent embodiments.
In conclusion, in the sending method for an assistance communication device provided by the embodiment of the present disclosure, the assistance communication device may obtain indication information for the assistance communication device, where the indication information includes the CSI and/or sending scheme, and then the assistance communication device may execute the precoding for the assistance communication device based on the indication information, to implement transceiving of signals.
