An eNode-B includes PUSH mapping hardware for improved performance. A scheduler schedules first and second code words of first and second respective user devices. A buffer receives and stores first and second identifiers. A de-multiplexer outputs a first code word number based on the first identifier and a second code word number based on the second identifier. A set of completion queues store the first and second code word numbers. A sequence controller generates first and second select signals corresponding to the first and second identifiers. A multiplexer outputs one of the first and second code word numbers based on the select signals, and the scheduler schedules the first and second code words based on the first and second identifiers.
