发明名称 METHOD AND APPARATUS FOR ASSURING QUALITY OF SERVICE IN WIRELESS LOCAL AREA NETWORKS
摘要 <p>A method and apparatus is described for maintaining quality of service (QoS) between a central controller and a set of mobile terminals (MTs) located within the coverage area of a basic service set (BSS) in a wireless local area network (WLAN). Upon a detection of a connection request by an MT and determining if adequate resources are available, establishing a connection with the MT using the most robust physical layer (PHY) mode with a sufficiently large set of packets to fulfill throughput requirements, if adequate resources are available and additional resources can be allocated. If adequate resources are not available, then attempting to allocate additional resources. In addition, a method is described for providing reliable transmission for a critical packet in a connection, including the steps of transmitting the critical packet at a first PHY mode; determining if adequate resources in the connection are available; and,transmitting a duplicate packet on a second PHY mode if adequate resources are available.</p>
