The disclosure relates to a LTE downlink control channel resource allocation method and base station. The method comprises that: a base station sends resource scheduling information to a physical layer via a MAC layer; the search space to which resources to be allocated belong is determined according to the scheduling information; when the resources to be allocated belong to dedicated search space of a UE, resources of the current downlink channel are allocated according to the quality level of the current downlink channel. The disclosure can dynamically and reasonably allocate PDCCH resources according to quality of the downlink channel, and can obtain the quality level of downlink channels through CQI fed back by the UE or BLER of HARQ or measurement result of the uplink channel, when quality of the downlink channel is unknown.
