Abstract
The present disclosure provides a method and an apparatus for determining number of ePDCCH resource units. The method includes: determining number of symbols occupied by PDCCH, number of CRS ports, number of DMRS ports and CSI-RS configuration in a subframe; and determining resources available for transmitting an ePDCCH in PDSCH area of the subframe according to the number of symbols occupied by the PDCCH, the number of CRS ports, the number of DMRS ports and the CSI-RS configuration.

A method for determining enhanced physical downlink control channel (ePDCCH) resources, comprising:
- determining number of symbols occupied by a physical downlink control channel (PDCCH), number of common reference signal (CRS) ports, number of demodulation reference signal (DMRS) ports and channel state information-reference signal (CSI-RS) configuration in a subframe;
- and
- determining resources available for transmitting an ePDCCH in a physical downlink shared channel (PDSCH) area of the subframe according to the number of symbols occupied by the PDCCH, the number of CRS ports, the number of DMRS ports and the CSI-RS configuration.
An apparatus for determining enhanced physical downlink control channel (ePDCCH) resources, comprising:
- a first determining unit, to determine number of symbols occupied by a physical downlink control channel (PDCCH), number of common reference signal (CRS) ports, number of demodulation reference signal (DMRS) ports and a channel state information-reference signal (CSI-RS) configuration in a subframe;
- and
- a second determining unit, to determine resources available for transmitting an ePDCCH in a physical downlink shared channel (PDSCH) area of the subframe according to the number of symbols occupied by the PDCCH, the number of CRS ports, the number of DMRS ports and the CSI-RS configuration.
