Abstract
A wireless communication system includes a plurality of wireless transmit/receive units (WTRUs) and an access point (AP). The AP communicates with the WTRUs via an antenna. In one embodiment, the AP configures the antenna to a wide beam configuration that covers a desired service area and transmits a Request-To-Send (RTS) control message. When the AP receives a Clear-To-Send (CTS) control message from one of the WTRUs, the AP determines optimal antenna settings for communication with the one WTRU. The AP configures the antenna to a narrow beam configuration and transmits at least one data packet to the one WTRU. When the AP receives an acknowledgement message indicating that the data packet was successfully received by the WTRU, the AP configures the antenna to the wide beam configuration. In another embodiment, the AP is configured to transmit and receive data packet fragments from the WTRUs and configure the antenna accordingly.
