step S201, the terminal device distributes the transmitting power of the terminal device in a first polarization and a second polarization based on first information; the first information includes: received signal strength and/or maximum transmit power.
In some embodiments, the terminal device allocates transmit power of the terminal device in the first polarization and the second polarization based on a maximum transmit power. The maximum transmit power includes: a first maximum transmit power of the first polarization and a second maximum transmit power of the second polarization.
When the terminal equipment does not need to carry out multi-stream transmission based on polarization, and the power P to be transmitted of the terminal equipment total A first maximum transmission power Pcmax less than or equal to said first polarization polar And the terminal equipment distributes all the power to be transmitted to the first polarization.
Here, the first polarization is an optimal propagation polarization of the first polarization and the second polarization, and the first polarization is characterized as the optimal propagation polarization when a first received signal strength of the first polarization in the first beam direction is greater than a second received signal strength of the second polarization in the second beam direction. The first beam direction is a beam direction corresponding to the maximum received signal strength of the first polarization obtained by measurement, that is, an optimal beam direction of the first polarization, and the second beam direction is a beam direction corresponding to the maximum received signal strength of the second polarization obtained by measurement, that is, an optimal beam direction of the second polarization.
When the terminal equipment does not need to carry out multi-stream transmission based on polarization, and the power P to be transmitted of the terminal equipment total A first maximum transmission power Pcmax greater than said first polarization polar Then the terminal device allocates full power to the first polarization, leaving the first polarizationResidual power is distributed to the second polarization; the residual power is a difference between the power to be transmitted and a first maximum transmission power of the first polarization. It can be understood that the power allocated by the terminal device for the first polarization is Pcmax polar The power allocated by the terminal device for the second polarization is P total -Pcmax polar 。

The received signal strength comprises: first received signal strength R of the first polarization in the first beam direction 1 And a second received signal strength R of the second polarization in the second beam direction 2 。
When a terminal device needs to perform multi-stream transmission based on polarization, the terminal device allocates a first transmit power to a first polarization, where the first transmit power is equal to a product of a to-be-transmitted power of the terminal device and a first weight, and the first weight is a ratio of a second receive signal strength of the second polarization in a second beam direction to a sum of a first receive signal strength of the first polarization in the first beam direction and the second receive signal strength. With P 1 Representing a first transmission power, P total And representing the power to be transmitted of the terminal equipment, and obtaining the first transmission power according to the following formula:
P 1 ＝P total *[R 2 /(R 1 +R 2 )] (1)

step S200, the terminal device measures the first received signal strength and the second received signal strength.
In specific implementation, after the terminal device accesses the network, under the condition of low-speed movement, the first polarization is turned on during downlink transmission, an optimal receiving beam direction (first beam direction) corresponding to the first polarization is searched, and the first received signal strength in the optimal receiving beam direction is measured. The greater the first received signal strength, the less the terminal device and the network device lose in the first polarization. Based on the same method, the second received signal strength of the second polarization in the optimal received beam direction (second beam direction) can be measured. And comparing the magnitudes of the first received signal strength and the second received signal strength, wherein the polarization corresponding to the larger one of the first received signal strength and the second received signal strength is the optimal propagation polarization.

For example, the first polarization is a horizontal polarization and the second polarization is a vertical polarization; or the first polarization is vertical polarization and the second polarization is horizontal polarization; or the first polarization is 45 ° polarization and the second polarization is 135 ° polarization; or a first polarization of 135 and a second polarization of 45.
