Frame structure and control signaling downlink coordinated multi-point (Comp) transmission

摘要

A method comprising establishing a coordinated multipoint "CoMP" control region in a subframe transmitted by an access node and configured to be receivable by a user equipment "UE". The CoMP control region may, for instance, comprise a plurality of control channel elements "CCEs", at least some of which are used for transmitting a physical downlink control channel "PDCCH" wherein the plurality of CCEs comprise a first set of CCEs and a second set of CCEs, and wherein the first set of CCEs comprise a non-CoMP control region and the second set of CCEs comprise a CoMP control region. The CoMP control region may, for instance, comprise at least one resource block and wherein a subframe comprises a plurality of control channel elements "CCEs", at least some of which are used for transmitting a physical downlink control channel "PDCCH". The CoMP control region may, for instance, comprise one or more CoMP resource blocks in a subframe, and wherein a downlink control information "DCI" format in one of a plurality of control channel elements "CCEs" of the subframe points to the one or more CoMP resource blocks.
