Abstract
A system and method of uplink acknowledgement transmission. The wireless network implements carrier aggregation wherein a subscriber station may be allocated downlink resource blocks distributed over multiple downlink carriers. The subscriber station receives control channel elements from at least one base station on at least two downlink carriers. The subscriber station derives uplink acknowledgement signal cyclic shift resource indices for respective carriers from functions of the index of the control channel elements that have carried a downlink grant the respective downlink carrier. The subscriber station transmits N number of ACK/NACK symbols in at least one physical uplink channel resource.
