- 無線通信システムにおける送信局(NodeB)から受信局(UE1,UE2)へのデータ伝送方法であって、
前記送信局(NodeB)はアンテナ装置(AV)を使用し、当該アンテナ装置は、前記受信局(UE1,UE2)の場所(P1,P2)で時間的に変化する電磁界強度(E1,E2)を伴う電磁界を生じさせ、
前記アンテナ装置(AV)は、空間的に別個にされた少なくとも2つのアンテナ(A1,A2)から構成され、当該アンテナはそれぞれ電磁波を送出し、当該少なくとも2つの電磁波は異なる周波数を有しているか、または、当該少なくとも2つの電磁波の相対的な位相位置は時間的に変化し、
前記送信局(NodeB)の制御ユニット(P)は、データ伝送前に、少なくとも2つの時点(t1',t1'',t2',t2'')での前記受信局が受信した信号のクオリティをあらわす少なくとも1つの情報(I1,I2)を前記受信局(UE1,UE2)から受信し、当該情報に基づいて送信局は前記電磁界強度(E1,E2)の時間的な経過特性を見積もり、
前記制御ユニット(P)はデータ伝送に対して、前記受信局(UE1,UE2)の場所(P1,P2)での、前記見積もられた電磁界強度(E1,E2)の時間的な経過特性に依存して、送信局が前記受信局(UE1,UE2)へデータ(D1,D2)を伝送する送信時点(t1,t2)を定め、当該送信時点は、前記各場所で電磁界強度が最大である時点である、ことを特徴とするデータ伝送方法。 - 前記少なくとも2つの電磁波の周波数は5〜50ヘルツだけ異なる、請求項1記載の方法。
- 前記伝送されるべきデータ(D1,D2)は、前記少なくとも2つの電磁波に変調により載せられる、請求項1記載の方法。
- 前記無線通信システムは移動無線システムである、請求項1から3までのいずれか1項記載の方法。
- 送信局(NodeB)であって、
受信局(UE1,UE2)の場所(P1,P2)で時間的に変化する電磁界強度(E1,E2)を有する電磁界を形成するアンテナ装置(AV)と、
前記受信局(UE1,UE2)の場所(P1,P2)での電磁界強度(E1,E2)の時間的な経過特性に依存してデータ伝送に対する送信時点(t1,t2)を定める制御ユニット(P)とを有しており、
前記アンテナ装置(AV)は、空間的に別個にされた少なくとも2つのアンテナ(A1,A2)から構成され、当該アンテナはそれぞれ電磁波を送出し、当該少なくとも2つの電磁波は異なる周波数を有しているか、または、当該少なくとも2つの電磁波の相対的な位相位置は時間的に変化し、
前記制御ユニット(P)は、データ伝送前に、少なくとも2つの時点(t1',t1'',t2',t2'')での前記受信局が受信した信号のクオリティをあらわす少なくとも1つの情報(I1,I2)を前記受信局(UE1,UE2)から受信し、当該情報に基づいて送信局は前記電磁界強度(E1,E2)の時間的な経過特性を見積もり、
前記制御ユニット(P)はデータ伝送に対して、前記受信局(UE1,UE2)の場所(P1,P2)での、前記見積もられた電磁界強度(E1,E2)の時間的な経過特性に依存して、送信局が前記受信局(UE1,UE2)へデータ(D1,D2)を伝送する送信時点(t1,t2)を定め、当該送信時点は、前記各場所で電磁界強度が最大である時点であり、
前記アンテナ装置(AV)は前記データ(D1,D2)を前記受信局(UE1,UE2)へ、前記送信時点(t1,t2)で伝送する、
ことを特徴とする送信局。
