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

[0033] An embodiment of the present invention provides a method for implementing multi-carrier power sharing, such as figure 2 shown, including the following steps:

[0034] 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.

[0035] 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 method and equipment for enhancing wireless coverage. The method comprises the following steps of: generating an output power regulating indication according to a test distance between a user terminal and a base station, or a coupling loss of the user terminal, or a useful signal power intensity of the base station received by the user terminal; and sending the output power regulating indication to the base station, and indicating the base station to share and distribute the multi-carrier output power according to the output power regulating indication. Under the condition that main hardware of base station such as power amplifier is not changed, the carrier output power is dynamically regulated according to the test distance or the coupling loss of the user terminal, or the useful signal power intensity of the base station received by the user terminal through scheduling a base station controller; the power share is enhanced, and an effect of enhancing the coverage and reducing the cost is equivalently achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and communication system for enhancing wireless coverage. 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 Multi...
