Abstract
Methods, systems, and apparatuses are described for providing device(s) with additional processing time to process a packet received wirelessly while still meeting the legacy SIFS time constraint. The additional processing time may be achieved by adding, by a device transmitting the packet, padding and/or a packet extension to the last symbol of the packet. The additional processing time provided to the device(s) advantageously reduces the amount of extra hardware that would normally be added to meet the SIFS time constraint. The amount of padding and/or packet extension to be added to the last symbol is balanced to minimize the complexity of the device(s) against the reduction in system efficiency incurred by the device(s).
