In order to make the solution shown in the embodiments of the present application easy to understand, several terms appearing in the embodiments of the present application will be described below.
First millimeter wave antenna: is an antenna for transmitting and receiving millimeter waves in a terminal. In a possible implementation manner, the number of the first millimeter wave antennas may be one, or may be multiple.
A temperature sensor: the terminal is used for acquiring the temperature of the first millimeter wave antenna. In one possible implementation, a temperature sensor is disposed proximate the first millimeter wave antenna for measuring a local temperature of the first millimeter wave antenna.
In the millimeter wave antenna array of the terminal according to the embodiment of the present application, according to the specification of the 3GPP TS38.101 protocol, the 5G NR mainly uses two-end frequencies, the FR1 frequency band and the FR2 frequency band. Wherein, the frequency range of the FR1 frequency band is 450MHz to 6GHz, also called sub-6GHz frequency band; the frequency range of the FR2 frequency band is 24.25GHz to 52.6GHz, commonly referred to as millimeter Wave (mm Wave). The 3GPP Release 15 Release specifies the current 5G millimeter wave frequency band. Wherein, n257(26.5GHz to 29.5GHz), n258(24.25GHz to 27.5GHz), n261(27.5GHz to 28.35GHz) and n260(37GHz to 40 GHz).
In the field of terminal antenna design, the number of sub-6GHz band signals from the 1G communication era to the 5G communication era generally increases with the number of bands and the number of antennas. In other words, fine optimization for antenna design, such as an increase in the number of wireless communication bands and an increase in the number of antennas. However, antenna designs for the millimeter-wave band have changed substantially, for example, antennas are organized into antenna arrays and beamforming techniques are employed. Currently, 3GPP defines two metrics describing the performance of millimeter wave terminals. One of the indexes is mm Peak isotropic Radiated Power (EIRP), and if the EIRP is too large, EMI (electromagnetic interference) to other systems is caused; if the EIRP is too small, effective wireless communication quality cannot be guaranteed, and the beam spherical spatial coverage, i.e., the three-dimensional CDF requirement of the terminal, affects network planning. Wider spatial coverage is more conducive to the wireless experience of the user, but wider spatial coverage often sacrifices the aggressiveness and attractiveness of the handset design, so that a proper tradeoff between the millimeter wave beam coverage and the overall competitiveness of the handset is required.
Among the specifications currently given by 3GPP, 3GPP TS38.101-2 specifies the specifications for EIRP.
Although millimeter wave beamforming antenna arrays have different design architectures and directions, the current mainstream and suitable direction of millimeter wave antenna arrays for mobile phones is generally based on phased array (phased antenna array) approach. The implementation of the phased array millimeter wave Antenna array can be mainly divided into three ways, namely AoB (Antenna on Board, i.e. Antenna array on system motherboard), AiP (Antenna in Package, i.e. Antenna array in chip Package), and AiM (Antenna in Module) and RFIC (radio frequency integrated circuit) to form a Module. Currently, the antenna mostly achieves its function by means of AiP or AiM.
However, the design emphasis of the millimeter wave beamforming antenna array is mainly as follows: the antenna array design and optimization method includes design and optimization capabilities of an antenna array (including a feeder network), selection and verification capabilities of a plate (substrate) and a coating (coating), design and optimization capabilities of an electrical system and a structural environment, design and implementation capabilities of a modular process, design and optimization capabilities of a software algorithm, and the like. For better beamforming to achieve the wider spatial coverage, antenna types (e.g., patch antenna, and quasi-Yagi antenna) with complementary radiation beams (e.g., broadside radiation and end-fire radiation) are commonly used to implement matching design, and based on proper design of antenna feed points, dual polarization (vertical and horizontal polarization) coverage is achieved to increase wireless communication connectivity. And the RFIC is inversely welded, so that the antenna feed wiring is shortened as much as possible, high path loss caused by high-frequency transmission is reduced, the millimeter wave antenna array has higher radiation gain, and better EIRP and coverage strength are achieved. The antenna is usually in the form of a patch antenna or a dipole antenna, the RFIC is usually packaged by a Flip-Chip process, and the antenna and the RFIC are interconnected by a carrier board process or an HDI (High Density interconnect board) process. By taking the millimeter wave antenna module QTM052 and QTM525 modules as examples, the QTM052 module covers 3GPP n261 and n260 band, and the QTM525 module covers 3GPP n258 and n261 band.

In this embodiment of the application, the terminal can read a reading set on the first millimeter wave antenna when the first millimeter wave antenna is in a working state, and the reading is the temperature of the first millimeter wave antenna. It should be noted that the terminal may determine the transmission power of the first millimeter wave antenna in the operating state, and in an application scenario, the meaning that the first millimeter wave antenna is in the operating state is that a signal is transmitted or received through the first millimeter wave antenna.

Where beam 406 is the downlink beam and beam 407 is the best uplink beam. The first millimeter wave antenna may select one of the beams for communication with the outside.
And step 320, when the temperature of the first millimeter wave antenna is greater than the temperature threshold, reducing the transmitting power of the first millimeter wave antenna to a target power, wherein the target power is less than the current transmitting power of the first millimeter wave antenna.
Illustratively, the terminal may be configured to reduce the transmission power of the first millimeter wave antenna to a target power when the temperature of the first millimeter wave antenna is greater than the temperature threshold, where the target power is less than the current transmission power of the first millimeter wave line.
It should be noted that, because the target power is smaller than the current transmission power of the first millimeter wave antenna, the thermal effect of the first millimeter wave antenna can be reduced to some extent, so that the local temperature of the first millimeter wave antenna is gradually reduced.
And 330, controlling the first millimeter wave antenna to continuously work according to the target power when the signal transmitted by the first millimeter wave antenna through the target power meets the preset signal quality requirement.
In this embodiment, the terminal may further determine whether the signal transmitted by the first millimeter wave antenna through the target power satisfies the preset signal quality. When the quality of the preset signal is met, the terminal still does not influence the normal receiving and sending of the signal when the temperature of the first millimeter wave antenna is controlled.

The signal quality measurement request is used for requesting the base station to measure the quality of the uplink signal sent by the first millimeter wave antenna.
In the present application, a terminal is able to send a signal quality measurement request to a base station. In one possible approach, the signal quality measurement request is sent to the base station as a response to the normal uplink signal.

In another possible manner, the terminal can select the gain of the first millimeter wave antenna to be larger than the gain of the beam currently used by the first millimeter wave antenna. Because the EIRP is the transmission power plus the gain, when the terminal selects the target beam of the first millimeter wave antenna whose gain is higher than the gain of the beam currently used by the first millimeter wave antenna, the terminal may reduce the transmission power of the first millimeter wave antenna, thereby reducing the heat productivity of the first millimeter wave antenna and realizing the reduction of the temperature of the first millimeter wave antenna.
