Methods and procedures of mac layer signaling for unequal modulation and new modulation and coding schemes in WI-fi

Abstract

Procedures for link adaptation and signaling are disclosed herein to support multiple modulation and coding schemes (MCSs) and equal modulation (EQM) and unequal modulation (UEQM). A first station (STA) may transmit, to a second STA, a first physical protocol data unit (PPDU) that can be used to estimate channel conditions between the first and second STA. The First STA may receive, from the second STA, a second PPDU including a medium access control (MAC) frame including a MAC header and a MAC frame body, wherein the MAC header comprises a control subfield further comprising a control subfield variant, wherein the control subfield variant comprises modulation and coding scheme (MCS) feedback (MFB) information, wherein the MFB information includes an indication of unequal modulation (UEQM) and UEQM information. The first STA may transmit, to the second STA, a third PPDU using at least one modulation scheme based on the received MFB information.
