Uplink carrier aggregation control method, device and terminal equipment

Abstract

The invention discloses an uplink carrier aggregation control method and device and terminal equipment. The method comprises the following steps: monitoring battery real-time data corresponding to preset battery parameters through a baseband chip when a radio-frequency transceiver of the terminal equipment performs information transmission in an N-path uplink carrier aggregation way, wherein N is an integer being greater than 1; and controlling the radio-frequency transceiver to reduce M paths of uplink carriers through the baseband chip if the battery real-time data do not satisfy preset index data, wherein M is smaller than N, and greater than or equal to 1 in order that the battery real-time data of the battery parameters corresponding to the rest of (N-M) paths of uplink carriers satisfy the preset index data. According to the method, the battery real-time data corresponding to the battery parameters of the terminal equipment are monitored, and the number of paths of the uplink carriers is reduced when the battery real-time data do not satisfy the preset index data, so that power consumption of the terminal equipment is controlled reasonably, and the user experience is balanced on the premise of ensuring the cruising ability of the terminal equipment.

Problems solved by technology

[0003] In the above-mentioned carrier aggregation technology, the carrier is divided into uplink carrier and downlink carrier. Due to the influence of the working mode and structure of the terminal equipment, the impact of the downlink carrier on the power consumption of the terminal equipment is not large; while the aggregation of uplink carriers, especially in different frequency bands The aggregation between multiple RF transmission paths requires simultaneous transmission. Since the RF transmission path, especially the RF power amplifier in it, is a high-power device, the uplink carrier has a higher power consumption than terminal equipment without carrier aggregation. Significant differences

That is, the power consumption of an uplink carrier aggregation terminal device will vary significantly with the strength of the terminal device signal and the registered frequency band. If the uplink carrier works in a frequency band with weak signal or high power consumption of the terminal device itself, it may Sacrifice the battery life of the terminal equipment in exchange for the data experience of the current terminal equipment
