Systems and methodologies are described that facilitate identifying
resources upon which an acknowledgment can be sent or received in a
wireless communication environment that leverages coordinated multi-point
(CoMP). The resources can be identified based upon a criterion that can
be identifiable to a non-anchor cell base station (as well as an anchor
cell base station, a mobile device, etc.). The criterion can be an
identifier corresponding to a mobile device, where the identifier maps to
a predetermined set of resources. Examples of the identifier can include
a media access control identifier (MACID), a cell radio network temporary
identifier (C-RNTI), a short C-RNTI, etc. Further, the criterion can be
physical resources corresponding to a transmission, where the
acknowledgment is responsive to the transmission. Moreover, the
acknowledgment can be sent or received in connection with a cooperation
technique (e.g., joint transmission via inter-site packet sharing,
cooperative beamforming, cooperative silence, . . . ).
