Apparatus and methods for millimeter wave coordinated monostatic sensing

An apparatus in an IEEE 802.11 EDMG station (STA), the apparatus comprising processing electronics and configured as a sensing initiator in a coordinated monostatic sensing operation to:

• sequentially transmit a plurality of DMG sensing request frames for the coordinated monostatic sensing operation, each one of the plurality of DMG sensing request frames transmitted to a different respective one of a plurality of sensing responders and comprising a STA ID field and a BW field, the BW field indicative of a channel to be used by said one of a plurality of sensing responders for transmitting a respective sensing PPDU,
• wherein each different one of the DMG sensing request frames holds a different respective STA ID field value which indicates an order of transmission of said one of the DMG sensing request frames, and
• wherein each different one of the DMG sensing request frames holds a different respective BW field value.

An apparatus in an IEEE 802.11 EDMG station (STA), the apparatus comprising processing electronics and configured as a sensing responder in a coordinated monostatic sensing operation to:

• during a transmission opportunity (TXOP) of an IEEE 802.11 contention based access period (CBAP), receive a DMG sensing request frame for the coordinated monostatic sensing operation, the DMG sensing request frame comprising a STA ID field and a BW field;
• and
• transmit a monostatic sensing PPDU beginning at a transmit time based at least in least in part on content of the DMG sensing part on content of the DMG sensing request frame, using a channel determined based at request frame, the monostatic sensing PPDU being one of a plurality of monostatic sensing PPDUs which are transmitted concurrently or overlapping in time with one another by each of a respective plurality of sensing responders, including the sensing responder, in the coordinated monostatic sensing operation, each of the plurality of monostatic sensing PPDUs being transmitted on a different respective channel.
