Method and device for transmitting enhanced physical downlink control channel E-PDCCH

摘要

The present invention relates to the field of communications, and discloses an enhanced physical downlink control channel (E-PDCCH) transmission method and device, the E-PDCCH comprising at least one E-PDCCH element. The method comprises: mapping at least one E-PDCCH element onto the pre-configured position of at least one resource block pair, the size of the resources of each resource block pair being greater than or equal to the size of the resources of two E-PDCCH elements, and the resources in the resource block pair used by each E-PDCCH element being parts of the resources of each resource block of the resource block pair; transmitting the E-PDCCH on the time frequency resources mapped in the resource block pair. The present invention produces enhanced PDCCH functionalities while fully utilizing time frequency resources.
