Abstract: A method pertaining to leftover bits processing for proportional round-robin resource unit (RU) parsing in extreme high-throughput (EHT) systems involves processing a stream of bits to provide processed bits. The method also involves transmitting the processed bits to a station (STA) over a combination of multiple resource units (RUs) assigned to the STA. In processing the stream of bits, the method may involve parsing the stream of bits to the combination of multiple RUs. Moreover, in an event of leftover bits remaining from the parsing, the method may further involve distributing the leftover bits to one or more RUs but not all RUs of the combination of multiple RUs.
