摘要
TD-SCDMA系统TDD的工作方式、丰富多彩的业务以及智能天线的应用,使得链路分析更为复杂,需要考虑多个方面的平衡,包括不同业务间、上行与下行、公共信道与业务信道、链路预算各参数间等。在不同区域,智能天线波束赋形效果不一,必须切实做好不同无线环境下的整体链路平衡。
Based on analyzing the channel of TD-SCDMA system, It mainly expatiates and analyses the factors that affect TD-SCDMA system link balance, including the function of different parameters, the link of different services, the link between downlink and uplink, the link between TCH and CCCH. In respect that smart antenna has the various impact on network in the various wireless environment, we try to strike a proper link balance between the both sides.
