    • A transmitting node (24) in an industrial wireless network (WN1) transmits a first number of bits (BS) to a receiving node (30), where at least one bit is partitioned into segments and each segment is transmitted at a different frequency according to a frequency transmission scheme. The receiving node (30) receives the number of bits (BS), determines the quality of each segment of a received bit, collects quality determinations of segments, forms a quality measure for each frequency through combining quality determinations of the corresponding frequency, compares each quality measure with a quality measure criterion, determines at least one frequency that does not fulfill the quality measure criterion and informs (FII) the transmitting node about frequencies for which the corresponding quality measures do not fulfill the quality measure criterion. The transmitting node receives the information (FII) and updates the frequency transmission scheme.
    • 工业无线网络(WN1)中的发送节点(24)向接收节点(30)发送第一数量的比特(BS),其中至少一个比特被分割为段,并且每个段以不同的频率被发送,根据 到频率传输方案。 接收节点(30)接收比特数(BS),确定接收到的比特的每个片段的质量,收集片段的质量确定,通过组合对应频率的质量确定来形成每个频率的质量度量, 质量测量标准,确定不符合质量测量标准的至少一个频率,并通知(FII)发送节点关于相应质量度量不符合质量测量标准的频率。 发送节点接收信息(FII)并更新频率传输方案。
