Summary:To provide a cellular network that mitigates co-channel interference.SOLUTION: In a cellular communication network 100, it is determined whether communication between one base station and a UE, 101 and 102 interferes with another UE 105 in the same cell 103 or different cell 106, and an interference parameter associated with an interference signal 110 received by the UE is identified. The base station 101 transmits the interference parameter to the UE, and the UE receives one or more parameters including information regarding a signal expected to cause intra-cell or inter-cell interference, and processes the received signal using the one or more parameters in order to suppress the intra-cell or inter-cell interference.SELECTED DRAWING: Figure 1 【課題】同一チャネル干渉を緩和するセルラーネットワークを提供する。【解決手段】セルラー通信ネットワーク１００において、一つの基地局とＵＥとのペア１０１、１０２間の通信が、同じセル１０３又は異なるセル１０６にある別のＵＥ１０５と干渉するか否かを判定し、ＵＥにより受信される干渉信号１１０に関連付けられる干渉パラメータを識別する。基地局１０１は、干渉パラメータをＵＥに送信し、ＵＥは、セル内又はセル間干渉を起こすことが予期される信号に関する情報を含む一つ又は複数のパラメータを受信し、ＵＥは、セル内又はセル間干渉１１０を抑制するため、受信した信号をこの一つ又は複数のパラメータを用いて処理する。【選択図】図１
