    Abstract: To prevent a situation that communication operation becomes unstable resulting from erroneous detection of a PDCCH in a mobile communication system having a system band comprised of a plurality of base frequency blocks, in a mobile terminal apparatus (10) provided with a downlink control signal decoding section (104) conf igured to determine radio resources designated by ARI (ACK/NACK Resource Indicator) fields of PDCCHs assigned to a plurality of base frequency blocks (CCs), and a retransmission response signal transmission control section (105) configured to control transmission of retransmission response signals in response to PDSCHs assigned to a plurality of base frequency blocks (CCs) based on the radio resources designated by the ARI fields, the retransmission response signal transmission control section (105) limits transmission of retransmission response signals in response to PDSCHs assigned to all the base frequency blocks (CCs) when the radio resources designated by a plurality of the ARI fields include a different radio resource.

    Abstract: 有線および無線通信ネットワークは、スループットの減少およびデータの損失をもたらすバースト干渉にさらされる可能性がある。 送信ネットワークデバイスおよび受信ネットワークデバイスを含む通信システムにおいて、送信ネットワークデバイスが、失敗したパケットの送信のパケットを再送信するための動的なビット割り当て技術を実装するように構成されうる。 受信ネットワークデバイスから再送信の要求を受信すると、送信ネットワークデバイスは、元のシンボルのビットを元のシンボルごとに2つ以上の構成要素シンボルの間に動的に割り当てることができる。 送信ネットワークデバイスは、時間ダイバーシティを利用するために、2つ以上の構成要素シンボルを1つまたは複数の再送信パケットの間に割り当てることができる。 送信ネットワークデバイスは、堅牢な再送信パケットを生成するために、変調方式および符号化方式ならびにその他の送信パラメータを変更することもできる。

    Abstract: PROBLEM TO BE SOLVED: To achieve dynamic interpretation of a transmission block size field in a layer 1/layer 2(L1/L2) control channel.SOLUTION: A signaling method includes a step for receiving control channel data, a step for determining whether or not the control channel data is at least one of retransmission, transmission of new data and the first time transmission, and a step for interpreting the control channel data dynamically based on the determination. The control channel data includes a transmission block size field, and the transmission block size field is interpreted to represent the transmission block size according to the determination that the control channel data is at least one of transmission of new data and first time transmission, and interpreted as an index representing a redundant version according to the determination that the control channel data is retransmission.

    Abstract: PROBLEM TO BE SOLVED: To prevent a situation where communication behavior becomes unstable resulted from an incorrect detection of a PDCCH in a mobile communication system having a system band comprising a plurality of basic frequency blocks.SOLUTION: A mobile terminal device 10 comprises: a downlink control signal decoding part 104 which determines a radio resource specified in the ARI (ACK/NACK Resource Indicator) field of the PDCCH allocated to a plurality of basic frequency blocks (CC); and a retransmission response signal transmission control part 105 which controls transmission of the retransmission response signal to the PDSCH allocated to the plurality of basic frequency blocks (CC) based on the radio resource specified in the ARI field. When the radio resource specified in the plurality of ARI fields includes a different radio resource, the retransmission response signal transmission control part 105 restricts transmission of the retransmission response signal to the PDSCH allocated to all basic frequency blocks (CC).
