Abstract
【解決手段】基本サービスシステムまたはセル内の複数のユーザ(101〜105)間の通信のための無線LAN(WLAN)システムにおいて、ポイント−マルチポイント通信をユーザに送信し(116)、前記ユーザから受信する(118)スイッチングアクセスポイント(SAP)(106)を備えた。複数のポートをSAPで利用することができ、ユーザ間の通信を分離して衝突を防止するために、永続的ではない周波数の割当能力で、および動的または疑似ランダム搬送波割当能力で、複数のポートが、単一の搬送周波数に各々割り当てられる。SAPの代替実施形態は、ビーム形成を用いて、複数のユーザへの割当のための空間的ポートを提供する。
