1. An apparatus, comprising:
a dynamic acknowledgement (ACK) list allocation circuit that searches ACK candidates to generate a dynamic ACK list that includes two most likely ACK candidates;
a top-Q candidate Channel Quality Indicator (CQI) bits detector that dynamically allocates a detection branch to each of the two most likely ACK candidates in the dynamic ACK list, and wherein the detection branches detect top-Q candidate CQI bits for the two most likely ACK candidates in the dynamic ACK list;
a merger circuit that mergers the top-Q candidate CQI bits detected for the two most likely ACK candidates in the dynamic ACK list to generate a merged list;
a top-Q CQI symbol generator that receives the merged list and generates top-Q CQI symbols for the top-Q candidate CQI bits detected for the two most likely ACK candidates in the dynamic ACK list; and
a joint detector that receives the top-Q CQI symbols and detects transmitted CQI bits and ACK bits.
