ENHANCED PHYSICAL DOWNLINK CONTROL CHANNEL (E-PDCCH) TRANSMISSION METHOD AND DEVICE

摘要

The present invention relates to the field of communications technologies and discloses a method and a device for transmitting an enhanced physical downlink control channel E-PDCCH. The E-PDCCH includes at least one E-PDCCH unit, and the method includes: mapping the at least one E-PDCCH unit to a pre-determined position in at least one resource block pair, where a size of resources of each resource block pair is greater than or equal to a size of resources occupied by two E-PDCCH units, and resources occupied by each E-PDCCH unit in a resource block pair include a part of resources of each resource block in the resource block pair; and transmitting the E-PDCCH on mapped time-frequency resources in the resource block pair. By using the present invention, better enhanced PDCCH performance may be obtained in a case that time-frequency resources are made full use of.
