Method for determining polarization information and related device thereof

A method for determining polarization information, comprising:

• generating, by a transmitting device, a first polarization information set, wherein the first polarization information set comprises at least one piece of first polarization information, the first polarization information comprising information indicating a polarization shape and a polarization direction of the transmitted electromagnetic wave of the transmitting device;
• sending, by the transmitting device, the first polarization information set to the receiving device, wherein the first polarization information set is used by the receiving device to determine a quality set of a received signal, the quality set comprises at least one piece of quality, the first polarization information corresponds to a quality of the received signal, and the received signal is a signal sent by the transmitting device to the receiving device through a non-line-of-sight (NLOS) channel;
• receiving, by the transmitting device, first optimal polarization information sent by the receiving device, wherein the first optimal polarization information belongs to the first polarization information set, and the first optimal polarization information corresponds to an optimal quality, the optimal quality is quality that has a minimum degradation degree of the received signal in the quality set;
• and
• determining, by the transmitting device, the polarization shape and the polarization direction of the transmitted electromagnetic wave based on the first optimal polarization information.

A receiving device, wherein the receiving device comprises a controller, a receiver, and a transmitter, wherein

• the receiver is configured to obtain a first polarization information set sent by the transmitting device through a control channel, wherein the first polarization information set comprises at least one piece of first polarization information, the first polarization information comprising information indicating a polarization shape and a polarization direction of a transmitted electromagnetic wave of the transmitting device;
• the controller is configured to determine a quality set of a received signal, wherein the quality set comprises at least one piece of quality, the first polarization information corresponds to a quality of the received signal, the received signal being a signal sent by the transmitting device to the receiving device through a non-line-of-sight (NLOS) channel, and
• the controller is further configured to determine an optimal quality in the quality set, wherein the optimal quality is quality that has a minimum degradation degree of the received signal in the quality set;
• and
• the transmitter is configured to send the first polarization information corresponding to the optimal quality to the transmitting device.
