Signaling for scheduled multi-user multiple-input multiple-output acknowledgement

Abstract

This disclosure describes systems, methods, and devices related to scheduled multi-user multiple-input multiple-output (MU-MIMO) acknowledgement. A device may determine a block acknowledgment schedule associated with one or more destination devices. The device may cause to send a multi-user multiple-input multiple-output (MU-MIMO) frame including the block acknowledgment schedule. The device may identify one or more acknowledgment frames received from at least one of the one or more destination devices based on the block acknowledgment schedule.

What is claimed is: 
     
         1 . A device of an initiator device, the device comprising storage and processing circuitry coupled to storage, the processing circuitry configured to:
 determine a block acknowledgment schedule associated with one or more destination devices;   cause to send a multi-user multiple-input multiple-output (MU-MIMO) frame including the block acknowledgment schedule; and   identify one or more acknowledgment frames received from at least one of the one or more destination devices, the one or more acknowledgement frames associated with the block acknowledgment schedule.   
     
     
         2 . The device of  claim 1 , wherein the MU-MIMO frame comprises one or more enhanced directional multi-gigabit (EDMG) aggregated medium access control (MAC) protocol data units (A-MPDUs). 
     
     
         3 . The device of  claim 2 , wherein a first A-MPDU of the one or more EDMG A-MPDUs is associated with a first destination device of the one or more destination devices. 
     
     
         4 . The device of  claim 1 , wherein the block acknowledgment schedule is included in a first sub-frame of the first A-MPDU. 
     
     
         5 . The device of  claim 4 , wherein the first sub-frame is repeated within the first A-MPDU. 
     
     
         6 . The device of  claim 4 , wherein the block acknowledgment schedule comprises a block acknowledgment transmission time (BATT) offset. 
     
     
         7 . The device of  claim 1 , wherein the BATT offset indicates to a first destination device a time to send a first acknowledgment to the first A-MPDU. 
     
     
         8 . The device of  claim 1 , wherein the block acknowledgment schedule comprises a next MU-MIMO frame time offset. 
     
     
         9 . The device of  claim 1 , further comprising a transceiver configured to transmit and receive wireless signals. 
     
     
         10 . The device of  claim 9 , further comprising one or more antennas coupled to the transceiver. 
     
     
         11 . A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors of a responding device result in performing operations comprising:
 identifying a multi-user multiple-input multiple-output (MU-MIMO) frame including a block acknowledgment schedule; and   causing to send a block acknowledgment frame to the initiator device based on the block acknowledgment schedule.   
     
     
         12 . The non-transitory computer-readable medium of  claim 11 , wherein the MU-MIMO frame comprises one or more enhanced directional multi-gigabit (EDMG) aggregated medium access control (MAC) protocol data units (A-MPDUs). 
     
     
         13 . The non-transitory computer-readable medium of  claim 11 , wherein the MU-MIMO frame comprises a first A-MPDU associated with the responding device. 
     
     
         14 . The non-transitory computer-readable medium of  claim 13 , wherein the block acknowledgment schedule is included in a first sub-frame of the first A-MPDU. 
     
     
         15 . The non-transitory computer-readable medium of  claim 14 , wherein the first sub-frame is repeated within the first A-MPDU. 
     
     
         16 . The non-transitory computer-readable medium of  claim 11 , wherein the block acknowledgment schedule comprises a block acknowledgment transmission time (BATT) offset. 
     
     
         17 . The non-transitory computer-readable medium of  claim 16 , wherein the BATT offset indicates to a first destination device a time to send a first acknowledgment to the first A-MPDU. 
     
     
         18 . A method comprising:
 determining, by one or more processors, a block acknowledgment schedule associated with one or more destination devices;   causing to send a multi-user multiple-input multiple-output (MU-MIMO) frame including the block acknowledgment schedule; and   identifying one or more acknowledgment frames received from at least one of the one or more destination devices, the one or more acknowledgement frames associated with the block acknowledgment schedule.   
     
     
         19 . The method of  claim 18 , wherein the MU-MIMO frame comprises one or more enhanced directional multi-gigabit (EDMG) aggregated medium access control (MAC) protocol data units (A-MPDUs). 
     
     
         20 . The method of  claim 19 , wherein a first A-MPDU of the one or more EDMG A-MPDUs is associated with a first destination device of the one or more destination devices.
