Patent ID: 8675575

Claim:
A method comprising: transmitting, by a device, at least one data block comprising at least one field to one or more stations, the at least one field comprising a very high throughput signal (VHT-SIG-B) field that includes an offset value, the VHT-SIG-B field is transmitted in a beam formed fashion to facilitate differing offset value for each station, wherein the offset value indicates start and end of transmission of a block acknowledgement by each station; receiving, by the device, of the block acknowledgement from each station, where an order of receiving the block acknowledgement is based upon the transmitted offset value; transmitting, by the device, of a schedule frame that includes station association identification (STA-AID) fields, the STA AID fields facilitate a desired order of transmitting a response by each station; and receiving in the desired order, by the device, of the response from the one or more stations; transmitting a null data packet frame that solicits a beam form (BF) feedback frame as the response, the response is appended to the block acknowledgement (BA) during a transmission by the station to the device.
