Abstract  Abstract

The invention claims for transmission from a node in the physical resource block (PRB) pair of enhancement type physical downlink control channel (ePDCCH) of the distributed control channel element (CCE) and technology of centralized CCE. and a physical resource block (PRB) allocation (RA) technology is used for the wireless device using at least one enhanced type physical downlink control channel (ePDCCH) for a physical downlink shared channel (PDSCH). A method may include node PRB pair of at least one distributed CCE and at least one centralized CCE to do pre-coding. node may use at least two of user equipment specific reference signals (UERS) port for transmission for at least one distributed CCE transmission diversity and transmit at least one centralized CCE in the PRB. at least two URES ports can be used for transmitting two CCEs.

Technology for transmitting a distributed control channel element (CCE) for an enhanced physical downlink control channel (ePDCCH) and a localized CCE in a physical resource block (PRB) pair from a node and technology for physical downlink shared channel (PDSCH) physical resource block (PRB) allocation with at least one enhanced physical downlink control channel (ePDCCH) at a wireless device is disclosed. One method can include a node precoding at least one distributed CCE and at least one localized CCE for the PRB pair. The node can transmit the at least one distributed CCE for transmit diversity using at least two user equipment-specific reference signal (UERS) ports and transmitting the at least one localized CCE in the PRB pair. The at least two UERS ports can be used to transmit two CCEs.
