Reporting mechanisms for wireless communications

Abstract

This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer-readable media, for reporting Quality of Service (QoS) feedback information. A method of wireless communication at an apparatus may include selecting, from a variable number of control fields, one or more control fields for inclusion in a frame, each control field comprising a control identifier field and a control information field. The control identifier field may include an indicator indicating a type of information for communication is QoS feedback information. The control information field may include one or more subfields containing the QoS feedback information. The method may further include generating the frame comprising the selected number of control fields, and outputting the frame for transmission.
