Problems solved by technology

Limiting the cooling effect of transmit power measures, such as reducing PA and RF power consumption, is the best way to cool down, but this way will lead to the failure of sending uplink data / control signaling, and even increase the risk of service link disconnection

Embodiment Construction

[0039] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0040] When the temperature exceeds the set threshold, limiting the uplink transmit power is an effective means, but if the uplink power of the wireless signal is reduced, the uplink data transmission may fail, and even uplink loss of synchronization and service link disconnection may occur. In order to facilitate the explanation of this problem, the following two reasonable assumptions are made:

[0041] Hypothesis 1: Regardless of factors such as uplink interference from other users, assuming the same rate (Radio Bearer (RB, Radio Bearer) and Modulation and Coding Scheme...

Abstract

The embodiment of the invention discloses a temperature control method and device as well as a terminal. The method comprises the following steps: when detecting that the temperature exceeds the set threshold temperature, detecting channel quality parameters of an uplink traffic channel in a set time period, and adjusting the maximum transmit power rollback value in the next set time period according to the channel quality parameters; and adjusting the uplink transmit power based on the adjusted maximum transmit power rollback value in the next set time period. According to the method, device and the terminal disclosed by the embodiment of the invention, the maximum transmit power rollback value of a power amplifier can be adjusted according to the detected channel quality parameters, and thus when a transmitter performs power adjustment based on the current maximum transmit power rollback value, the transmit power of wireless signals can be ensured, and the power amplifier, a radio frequency module and other components with a relatively high heating level can also maintain a relatively low temperature, and thereby, the temperature control can be achieved, the transmit power of the wireless signals can also be ensured, the service interruption caused by link disconnection cannot occur, and the communication performance of wireless services can be ensured.

Description

technical field [0001] The present invention relates to temperature control technology, in particular to a temperature control method, device and terminal suitable for uplink signal transmission. Background technique [0002] After the temperature sensor detects that the chip temperature is too high, the conventional cooling strategies include: frequency reduction, voltage reduction, speed limit, power limit, exit from the business connection state, restart the module, shutdown, etc., generally according to the position of the temperature sensor in the chip And the temperature range to start the corresponding cooling strategy. [0003] From the theoretical analysis and the measured data of the power amplifier (PA, Power Amplifier), radio frequency (RF, Radio Frequency) transmission (TX) path temperature sensor, the uplink data / control signaling channel is the dominant factor of the heating problem. Limiting the cooling effect of transmit power measures, such as reducing PA ...
