Abstract
Description
本願は、同一出願人が所有し、参照により全体が本明細書に組み込まれる、2013年5月6日に出願された「METHOD AND APPARATUS FOR COORDINATED BEAMFORMING」と題する仮特許出願第61/820166号からの優先権を主張する。
− 単一の送信機または多数の送信機は、同じユーザに、または異なる目標および/またはユーザに誘導される多数のビームを同時に形成することができる。
− 送信機は、送信する、ジャミングする、盗聴する、またはそれらを組み合わせるためにマルチ・ユーザ多入力多出力(MU−MIMO)を同時に使用することができる。
− すべての利用可能なトランシーバから1組のトランシーバ、
− 選択されたトランシーバのすべての利用可能なビームから1組のビーム、
および
− 選択されたトランシーバの選択されたビームで動作するすべての利用可能な通信リソースから1組のリソース(例えば、周波数チャネル、コード・シーケンス、他の物理レイヤ・パラメータ))。
のうちの1つまたは複数をいつでも知能的に決定することによって伝達される。
− 時間t1に、周波数チャネルf1でビームB2を使用する送信機Tx1によって、
− 時間t2に、周波数f2でビームB18を使用する送信機Tx6によって、
− 時間t3に、周波数f3でB2を使用する送信機Tx1と、周波数f4でBk−2を使用する送信機TxMとによって共同で送られる。図示のように、ビーム・ステアリングを利用して、異なるPHY性質をもつ独特の空間チャネルを作り出すことができる。重要情報は、単一のビームでまたは多数のビームで随時送ることができる。後の場合、所期の受信機は、多数のビームを介して送られた情報を組み合わせて復号することができる。司令部ユニット/司令部は、送信機、ビーム、周波数チャネルなどを切り替えることができ、受信機が、使用中の通信リソースの新しい組に速く同調できる限り、いつでもそれらの通信リソースの任意の組合せを使用することができる。
