Control channel element indexing scheme
First Claim
1. A method, comprising:
- obtaining information regarding first partition elements, the first partition elements corresponding to channel resource elements carrying in downlink a configurable first control channel for allocating channel resources to a data channel according to a first partitioning, wherein the first control channel is an enhanced Physical Downlink Control Channel;
determining a number of second partition elements according to a second partitioning of each of the first partition elements, the second partition elements comprising enhanced Control Channel Elements, wherein the enhanced Control Channel Elements can be extended into the enhanced Physical Downlink Control Channel;
determining for at least one second partition element a second-partition element index based on the obtained information regarding the first partition elements and the determined number of second partition elements, wherein;
either the second partition elements are indexed according to a transmission point specific indexing scheme, orat least one of the second-partition element index and information regarding first partition elements is unique per user equipment;
determining for at least one third partition element related to a third partitioning of channel resource elements, a third-partition element index;
receiving a data packet transmitted on the data channel; and
providing feedback information in uplink direction on a second control channel about successful or unsuccessful reception of the data packet, wherein the second control channel is a Physical Uplink Control Channel, wherein;
the first partitioning is related to a partitioning used for allocating channel resources to the data channel,the second partitioning is related to the allocation of channel resources of the first control channel, andthe third partitioning is related to allocating channel resources of the second control channel.

Abstract
The present invention provides a method, a apparatus and computer program product relating to a control channel element indexing scheme. The present invention includes obtaining information regarding first partition elements related to a first partitioning of channel resource elements carrying in downlink a configurable first control channel associated with a data channel, determining a number of second partition elements related to a second partitioning of channel resource elements per first partition element, determining for at least one second partition element a second-partition element index based on information regarding the first partition elements and the determined number, determining for at least one third partition element related to a third partitioning of channel resource elements, a third-partition element index, wherein the second partitioning is related to the allocation of channel resources of the first control channel, and wherein the third partitioning is related to allocating channel resources of a second control channel.
