摘　　要：LTE是3G之后一个很有前景的移动通信技术。LTE中,网络基于终端上报的上行控制信息(即CQI、RI、PMI)进行调度。终端经过测试后发现现网中网络存在多种调度策略,如完全按终端上报信息调度、完全按自己的策略调度。经分析,建议网络和终端都有自身的策略,两者相对独立,但上报或调度策略的目标是相同的,即在保证通信质量的前提下,提高数据吞吐量。LTE is a promising technology of mobile communications after 3G. In LTE, base station（eNB） scheduling physical resource or modulation and coding scheme based on uplink control information （UCI）, that is CQI, RI, or PMI, reported from UE. After testing, there are kinds of schedule strategy in current networks. Some eNBs scheduling based on UCI totally, and others just reference them. Proposed strategy of eNB and UE should be independent relatively, with one same target. The target is that acquire higher throughout canacitv in condition ofaccentable communication auality.
