W2 W3可與很少數的無線傳送/接收單元(WT她) 而被分別投射至Pl、P2、p3位置中,而較窄的波束Νι、N5、 N6與多數的無線傳送/接收單元(WTRUs)而被分別投射至p4、 P5、P6位置中。此促進了在較密集區域中較窄的專用波束B的 產生,同時也增加共用頻道上行與下行使用的處理容量, 進而建立最初的通訊。 波束寬度的操作最好是即時執行,然而,通訊的狀況與應 用的本質決定了波纽置Pl、Pn的數目的適合性與其相關聯 201012249 波束寬度型式。形成的波束型式應具有足夠的寬度,如此無線 傳送/接收單元(WTRUs)進入與離開波束的數目可在無過度的 遞交(handoff)至其他的波束下被操控。一個靜態的裝置可由一 窄波束而被服務’例如,迅速移動的汽車不能經由與流量正交 的一窄波束而被有效率的服務,但是,可經由平行於傳導方向 的一窄波束而被服務。一個窄的正交波束僅能滿足短的訊息服 務,並不能用來做聲音服務,例如電話。 “ 使用不同波束寬度的其他優點是在一地區内無線傳送/接 收單元(WTRUs)移躺本f。請翔帛六目,顯示—建築物 BL(代^料最妓機_動步槐雜^ wtrUs的區域) 與-高速資訊通路(highWay)H(代表具有最初是較快移動裝置 WTRUs的區域)。較緩慢速度的裝置资舰 服務,魏魏顺軸隨找。 動裝置WTRUs需要較寬的波束黔%以支援一通訊。
