Abstract

The invention relates to the technical field of wireless communication, in particular to a self-adaptation system for unbalanced uplinks and downlinks and a method thereof. The system includes a wireless digital relay device for conducting wireless signal transmission with a base station and a terminal through an antenna; the wireless digital relay device includes a first radio transceiver module (11) which conducts wireless signal transmission with the base station (1), a second radio transceiver module (21) which conducts wireless signal transmission with the terminal (2), a FPGA processing module (3) which is used for judging signals transmitted and sent by the first radio transceiver module (11) and signals transmitted and sent by the second radio transceiver module (21), and configuring an uplink transmitting channel to the FPGA processing module with a designated terminal, and a modulation and demodulation module (4). The self-adaptation system for unbalanced uplinks and downlinks and the method thereof solve the problem of unbalanced uplinks and downlinks under the scenes of broad coverage and deep coverage, and avoid the problems that single pass, call drop and frequent switching happen and the number is not in service when being called because of unbalanced uplinks and downlinks. The user perception can be improved well, and complaints are reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an adaptive system and method for unbalanced uplink and downlink. Background technique [0002] Since the wireless signal attenuates with the increase of the propagation distance, and in different environments, the occlusion, reflection, refraction and absorption of buildings or plants will also cause the wireless signal to attenuate rapidly in some scenarios, so in The cell edge in the wide coverage area or the deep indoor coverage area will lead to insufficient signal strength and poor user communication performance. [0003] In GSM (Global System for Mobile Communications, Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) and LTE (Long Term Evolution, Long Term Evolution) FDD (Frequency Division Duplex, Frequency Division Duplex) systems, The uplink signal and the downlink...
