Method and apparatus for establishing a mapping between enhanced downlink control channel resource and antenna port

An apparatus for establishing a mapping between an enhanced downlink control channel resource and an antenna port, comprising:

• a resource mapping unit, configured to establish a mapping between each resource element in an enhanced downlink control channel resource and an antenna port;
• and
• a data mapping unit, configured to establish a correspondence between control data carried by the resource element and an antenna port corresponding to the resource element, so as to send or receive, according to a reference signal corresponding to the antenna port, the control data carried by the resource element.

An apparatus for mapping between an enhanced downlink control channel resource and an antenna port, comprising:

• a processor, configured to establish a mapping between each resource element in an enhanced downlink control channel resource and an antenna port, and establish a correspondence between control data carried by the resource element and an antenna port corresponding to the resource element;
• and
• a memory, configured to store the mapping established between each resource element and an antenna port by the processor and to store the correspondence established between the control data and an antenna port by the processor.
