Abstract

The invention provides a system and method for relaying and amplifying signals in a wireless communication system. The system comprises a baseband chip and a first radio frequency transceiver chip. The baseband chip is suitable for presetting a first preset power. The first radio frequency transceiver chip is suitable for amplifying a first received signal, and mixing with lower frequency to obtain a first intermediate signal. The baseband chip is also suitable for controlling the gain during the power amplification of a second radio frequency transceiver chip based on the power of the first intermediate signal and the first preset power. The system comprises the second radio frequency transceiver which is suitable for amplifying the first intermediate signal to the first preset frequency to acquire the first sending signal. The system applies the already-existent communication baseband chip and radio frequency transceiver chip as the main body of the signal relaying and amplifying system, uses the baseband chip as the control unit, based on the preset gain for power amplification, controls the behaviors of the radio frequency transceiver chip. Compared with the prior art, the system has the advantages of being capable of controlling the gain conveniently during power amplification.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a signal relay amplification system and method in a wireless communication system. Background technique [0002] In a wireless communication system, the use of a user terminal has certain requirements on the signal strength of the area where it is located. In the edge area of ​​the mobile base station signal, due to insufficient signal strength, user terminals and similar equipment cannot be used normally. [0003] By increasing the receiving power consumption of the user terminal, the ability to receive low-intensity signals can be enhanced, but this method is usually not feasible due to the limitations of the mobile communication protocol and the battery capacity of the user terminal. [0004] The mobile signal relay amplifier is used to receive and amplify the mobile base station signal in a certain area for use by nearby user terminals, which can effectively s...
