Problems solved by technology

[0003] The performance of the power amplifier (Power Amplifier, PA) of the millimeter-wave terminal is greatly affected by the external environment and the thermal noise of the terminal itself, which leads to the inability to directly apply low-frequency PA linearization improvement technologies such as pre-distortion, which makes the linear transmission of the millimeter-wave terminal Low power, limited uplink coverage

Embodiment Construction

[0030] The technical solutions in the present application embodiment will be described below with reference to the drawings.

[0031] Example, Figure 1A A wireless communication system according to the present application is shown. The wireless communication system 100 can operate on a high-frequency band, not limited to the long-term evolution (LTE) system, can also be the fifth generation of mobile communication (The 5th Generation, 5G) system, new vacation (NR) ) System, machine and machine communication (MachineTo Machine, M2M) system, etc. The wireless communication system 100 can include: one or more network devices 101, one or more terminals 103, and core network devices 105. The network device 101 can be a base station, and the base station can be used to communicate with one or more terminals, or may be used to communicate with a base station having a portion of the terminal function (such as a macro base station and the micro base station). The base station can be the ba...

Abstract

The embodiment of the present application discloses an output power adjustment method and related products, including: starting the power amplifier PA self-calibration process of the first transmission channel Tx1 within the first uplink calibration time window to obtain the first pre-distortion calibration file, the first A pre-distortion calibration file is used to determine the first high transmit power after pre-distortion, and the terminal is in the connected state; within the second uplink calibration time window, start the PA self-calibration process of the second transmission channel Tx2, and obtain the second pre-distortion A distortion calibration file, the second pre-distortion calibration file is used to determine the second highest transmit power after pre-distortion. The embodiment of the present application is beneficial for the terminal to obtain higher linear output power in real time, so as to achieve the purpose of improving PA linearity and uplink coverage.

Description

Technical field [0001] The present application relates to the field of communication, in particular, to an output power adjustment method and related products. Background technique [0002] The terminal in the network includes a idle state and a connection state. When the terminal is in the connection state, except for the cell edge scene, if a large amount of data needs to be sent, the transmit power is also required, which is transmitted to the terminal. Power propose requirements. [0003] The performance of the power amplifier, PA of the millimeter wave terminal is highly affected by the thermal noise of the external environment and the terminal itself, resulting in a linearization of PA of low frequency bands, such as psychoharmonic, etc., so that millimeter wave terminal linear emission Low power, uplink coverage is limited. Inventive content [0004] Embodiments of the present application provide an output power adjustment method and related product, which facilitates a h...
