PERFORMING NETWORK MEDIUM RESERVATION IN A WIRELESS NETWORK AND FRAGMENTING OR AGGREGATING MAC- PROTOCOL DATA UNITS

摘要

The method for a wireless network that utilizes adaptive modulation techniques and supports a short-NAV type wireless medium reservation scheme comprises the steps of : - receiving a first wireless frame from a remote network device, said first wireless frame having a medium reservation period associated with it to reserve a network medium for a subsequent transmission to said remote network device (122, 132) , - determining a data rate to use to transmit user data to said remote network device (124, 134) , and - when said data rate does not allow an entire data MAC protocol data unit (MPDU) to be transmitted in a data frame within said medium reservation period, fragmenting said data MPDU to identifiy a first fragment that can be transmitted in a data frame within said medium reservation period (126) .
