Leftover bits processing for proportional round-robin resource unit parsing in extreme high-throughput systems

An apparatus, comprising:

• a transceiver configured to communicate wirelessly;
• and
• a processor coupled to the transceiver and configured to perform operations comprising:
• processing a stream of bits to provide processed bits;
• and
• transmitting, via the transceiver, the processed bits to a station (STA) over a combination of multiple resource units (RUs) assigned to the STA,
• wherein the combination of multiple RUs comprises at least one smaller RU and at least one larger RU with the at least one larger RU having more tones than the at least one smaller RU,
• wherein, in processing the stream of bits, the processor is configured to perform operations comprising:
• parsing the stream of bits to the combination of multiple RUs in a proportional round-robin fashion;
• and
• in an event of leftover bits remaining from the parsing in the proportional round-robin fashion, distributing the leftover bits to the at least one larger RU,
• wherein the combination of multiple RUs comprises a first combination, a second combination, a third combination or a fourth combination,
• wherein the first combination comprises one smaller RU of 484 tones and two larger RUs of 996 tones,
• wherein the second combination comprises one smaller RU of 484 tones and three larger RUs of 996 tones,
• wherein the third combination comprises one aggregated RU and one larger RU of 996 tones with the aggregated RU comprising one smaller RU of 242 tones and one smaller RU of 484 tones, and
• wherein the fourth combination comprises one smaller RU of 242 tones and one larger RU of 996 tones.

A method, comprising:

• processing a stream of bits to provide processed bits;
• and
• transmitting the processed bits to a station (STA) over a combination of multiple resource units (RUs) assigned to the STA,
• wherein the processing of the stream of bits comprises:
• parsing the stream of bits to the combination of multiple RUs;
• and
• in an event of leftover bits remaining from the parsing, distributing the leftover bits to one or more RUs but not all RUs of the combination of multiple RUs,
• wherein the combination of multiple RUs comprises at least one smaller RU and at least one larger RU with the at least one larger RU having more tones than the at least one smaller RU,
• wherein the distributing of the leftover bits comprises, for N iterations of parsing the stream of bits to the combination of multiple RUs, distributing the leftover bits over the at least one larger RU, and
• wherein N is an integer equal to or greater than 1.
