摘要： In triggering a handoff by a wireless transmit/receive unit (WTRU) from a current basic service set (BSS) in a wireless local area network (WLAN), the following are performed. A highest class of traffic service and quality of service (QoS) is determined for the highest class from a basic service set (BSS) beacon. Handoff is terminated and communication is retained with a current BSS when the signal to noise ratio (SNR) or received signal strength (RSS) is greater than a high threshold of the highest class. Other criteria is evaluated to determine whether a handoff is desired when the SNR or RSS is less than the high threshold.

摘要： The present invention is directed to methods and wireless communication devices that are configured to enhance communication capacity in a wireless network. In one aspect of the invention various scheduling processes and schedulers for the transmissions of data packets are disclosed. In another aspect of the invention, the selection of appropriate transmission rates to advertise by a common unit which provides wireless service to different types of wireless transmit receive units (WTRUs) is addressed.
