Trigger frame with security user info field

A method for wireless communication, comprising:

• generating, by a first device, a Trigger frame for soliciting a responsive physical layer (PHY) protocol data unit (PPDU), the Trigger frame including:
• at least one User Info field carrying uplink scheduling information for at least one recipient wireless device;
• at least one intermediate Frame Check Sequence (I-FCS) User Info field carrying an I-FCS value;
• and
• a Feedback User Info field carrying feedback information of the first device;
• and
• transmitting the Trigger frame for reception by the at least one recipient wireless device.

A communication device, comprising:

• one or more wireless transceivers;
• and
• one or more processors operably coupled to the one or more wireless transceivers, wherein the one or more processors are arranged to:
• generate a Trigger frame, the Trigger frame including:
• at least one User Info field carrying uplink scheduling information for at least one recipient wireless device;
• and
• a plurality of Security User Info fields, the plurality of Security User Info fields carrying a packet number (PN) and message integrity check (MIC) value (PN+MIC value);
• and
• transmit, via the one or more wireless transceivers, the Trigger frame for reception by the at least one recipient wireless device.
