Abstract  Abstract

claims a method for an enhanced physical downlink control channel mapping technology to radio frame in the physical resource block described herein. A method includes separately encoding the signs of the modulation mapping is ePDCCH to at least one control channel element. the at least one control channel element can be mapped to a plurality of distributed physical resource block in the sub-frame of the resource elements wherein each resource block in the distributed resource block groups and separating at least one additional resource block in the sub-frame. mapping can be to a single resource block in the sub-frame distribution of resource elements wherein a control channel element mapping forming other mapping relative to resource elements in a single resource block in frequency and time is distributed and a single resource block belonging to the centralized resource block groups.

Technology for mapping an enhanced physical downlink control channel to physical resource blocks in a radio frame is disclosed. One method comprises mapping modulated symbols in the ePDCCH to at least one control channel element. The at least one control channel element may be mapped to resource elements located in a plurality of distributed physical resource blocks in a subframe wherein each resource block is in a distributed resource block group and is separated by at least one additional resource block in the subframe. The mapping may also be to resource elements distributed in a single resource block in the subframe wherein the control channel element is mapped to be distributed in frequency and time relative to other mapped resource elements in the single resource block and the single resource block belongs to a localized resource block group.
