摘要:
This application provides an enhanced physical downlink control channel transmission method and apparatus. The method includes: in a physical resource block set, separately arranging first resource groups in each physical resource block pair PRB pair, where the first resource groups are resource element groups eREGs or REGs, and the physical resource block set includes at least one of the physical resource block pairs; numbering second resource groups according to a correspondence between the first resource groups and the second resource groups in the physical resource block set, where the second resource groups are control channel element eCCE groups or control channel candidates; determining numbers of the second resource groups for transmitting an E-PDCCH; and mapping, according to the determined numbers, the E-PDCCH to the corresponding first resource groups for transmission. The technical solution of this application resolves an E-PDCCH transmission problem.
