摘　　要：为了克服传统长期演进无线接入网的缺陷,讨论增强物理下行控制信道的可能性,并给出针对物理下行控制信道的增强方案,包括资源预留、联合发射、跨载波调度、增强的物理下行控制信道及其进一步的增强,由此可解决传统长期演进无线接入网协调不充分、难于实现的问题。As to drawbacks of the legacy long term evolution radio access network defects,this paper gives the possibility to enhance the physical downlink control channel.The proposed solu-tions to enhance the physical downlink control channel include resource reservation,joint trans-mission,cross-carrier scheduling enhanced physical downlink control channel and its further en-hancement.Problems on insufficient coordination and difficulty in implement in the legacy long term evolution radio access network are solved.
