Systems and methodologies are described that facilitate assigning uplink resources for utilization by a mobile device for sending an uplink signal in an uplink coordinated multi-point (CoMP) wireless communication environment. For instance, a hopping tree can be defined across base stations, and neighboring base stations can schedule interfering mobile devices upon uplink resources mapped to different nodes from the hopping tree. By way of another example, a plurality of hopping trees can be employed across base stations in the uplink CoMP wireless communication environment. Moreover, an acknowledgment can be sent to the mobile device upon downlink resources identified as a function of the uplink resources. Further, the downlink resources can be distinct from disparate downlink resources utilized for sending an acknowledgment to a disparate mobile device from a neighboring base station.
