    • The present invention relates a method and a decoder for decoding codewords, the decoding being performed as message passing on a graph representation of the code, e.g. on low density parity-check (LDPC) code, wherein for each non-zero entry in a parity check matrix, the message matrix elements of a first message matrix are initialized with data obtained from a demodulator, and the elements of a second message matrix are determined based on message matrix elements of said first message matrix. Further, a decoded codeword is reconstructed based on the data obtained from the demodulator and the matrix elements of the second matrix. Moreover the present invention relates to and to a communication system, a mobile terminal and a base station comprising the decoder. To reduce the influence of wrong information the decoding method uses subset of matrix elements from said first/second matrix for determining a matrix element of said second/first matrix, wherein the matrix elements of said subset fulfill a reliability criterion.
    • 本发明涉及用于对码字进行解码的方法和解码器,该解码是作为在代码的图形表示上传递的消息来执行的。 在低密度奇偶校验(LDPC)码中,其中对于奇偶校验矩阵中的每个非零条目,使用从解调器获得的数据来初始化第一消息矩阵的消息矩阵元素,并且第二消息矩阵的元素 基于所述第一消息矩阵的消息矩阵元素确定。 此外,基于从解调器获取的数据和第二矩阵的矩阵元素重构解码码字。 此外,本发明涉及通信系统,移动终端和包括解码器的基站。 为了减少错误信息的影响,解码方法使用来自所述第一/第二矩阵的矩阵元素的子集来确定所述第二/第一矩阵的矩阵元素,其中所述子集的矩阵元素满足可靠性标准。

    • The invention relates to a user equipment (UE) scheduled with uplink radio resources. At least one unlicensed cell is configured for communication between the UE and a base station(BS). The UE receives from the BS a first-stage uplink scheduling message. The UE determines whether the first-stage uplink scheduling message is valid, which comprises determining that it is valid in case one or more bits of one or more data fields in the first-stage uplink scheduling message are set to respectively predetermined values. The UE receives from the BS a second- stage uplink scheduling message related to the first-stage uplink scheduling message. The UE determines, when receiving the second-stage uplink scheduling message, that an uplink transmission is scheduled in case it determined that the first-stage uplink scheduling message is valid. The UE then performs, in case it determined that an uplink transmission is scheduled, an uplink transmission via the unlicensed cell.
    • 本发明涉及用上行链路无线电资源调度的用户设备(UE)。 至少一个非授权小区被配置用于UE与基站(BS)之间的通信。 UE从BS接收第一阶段上行链路调度消息。 UE确定第一阶段上行链路调度消息是否有效,其包括在第一阶段上行链路调度消息中的一个或多个数据字段的一个或多个比特分别被设置为预定值的情况下确定它是有效的。 UE从BS接收与第一阶段上行链路调度消息有关的第二阶段上行链路调度消息。 当UE确定第一级上行调度消息有效时,UE在接收到第二级上行调度消息时确定调度了上行传输。 然后,UE在确定上行链路传输被调度的情况下执行经由非授权小区的上行链路传输。
