Problems solved by technology

However, as the number of carriers supported by a channel increases, the peak-to-average ratio of the output signal increases, and the power amplifier fallback will also increase. If a power amplifier with higher output power is not used, the output power per carrier will also decrease, which will affect coverage.

Embodiment Construction

[0021] An embodiment of the present invention provides a method for implementing multi-carrier power sharing, such as figure 2 shown, including the following steps:

[0022] Step s200, according to the test distance or coupling loss between the user terminal and the base station or the useful signal power strength of the base station received by the user terminal, an output power adjustment instruction is generated; The distance between the user and the base station or the coupling loss between the two or the power strength of the useful signal received from the base station dynamically adjusts and allocates the output power value of each time slot and carrier of the base station, and sends out a power adjustment instruction.

[0023] Step s201, sending the output power adjustment instruction to the base station, instructing the base station to share and allocate the output power of multiple carriers according to the adjustment instruction. Specifically: the base station con...

Abstract

The invention discloses a implementing method and device for multi-carrier power sharing. The inventive method includes steps of: generating output power modulating instruction according to test distance between user terminal and base station, or coupling loss, or available signal power intensity of base station; sending the mentioned output power modulating instruction to base station, so as to instruct base station to distribute output power of multi-carrier for sharing according to the instruction. The invention dynamically modulates output power of carrier, improves power sharing, equivalently enhances coverage, reduces cost through scheduling of base station according to distance between user terminal and base station, coupling loss and intensity of available signal power received by user terminal, without changes on main hardware such as power amplifier.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for realizing multi-carrier power sharing. Background technique [0002] After more than 20 years of development of the GSM (Global System of Mobile communication, Global System for Mobile Communications) wireless communication network, there are already a large number of devices running on the network, and the network scale continues to grow at a relatively rapid rate, and the large configuration station type The proportion is getting bigger and bigger, but in the past, the equipment was mainly single-carrier transceivers. If you want to support large-configuration station types, you have to go through multiple combinations, the loss is large, and the efficiency will decrease. With the development of technology, multi-carrier The technology is widely used in WCDMA (Wideband Code Division Multiple Address, wideband code division multiple acces...
