Abstract: In a scenario of a flexible Ethernet, the number of Ethernet frame streams received by an Ethernet interface of a receiver and a bit width of each Ethernet frame stream may need to be adjusted. A corresponding scrambling circuit is disposed for each data segment in the Ethernet frame streams, so as to separately perform scrambling on each data segment, where the number of bits of each data segment is M. Furthermore, X scrambling circuits corresponding to X data segments in a first Ethernet frame stream may separately calculate scrambling results of the X data segments. Therefore, if an adjusted bit width of each Ethernet frame stream is an integral multiple of M, a corresponding number of scrambling circuits may be reconfigured to perform scrambling on each adjusted Ethernet frame stream.

Abstract translation: 在灵活以太网的情况下，可能需要调整接收机的以太网接口接收的以太网帧流数和每个以太网帧流的位宽度。 为以太网帧流中的每个数据段设置相应的加扰电路，以便对每个数据段的位数进行单独执行加扰，其中每个数据段的位数为M。此外，对应于X数据段的X个加扰电路 第一以太网帧流可以单独地计算X个数据段的加扰结果。 因此，如果每个以太网帧流的调整比特宽度是M的整数倍，则可以对相应数量的加扰电路进行重新配置，以对每个调整后的以太网帧流执行加扰。

Abstract: Example coverage mode identification methods and apparatus are described. One example method includes determining a first coverage mode by a terminal. The terminal determines a preamble sequence based on the first coverage mode, and sends the preamble sequence to a base station, where the preamble sequence is used to determine the first coverage mode. Because the base station can determine the coverage mode of the terminal by using only the preamble sequence sent by the terminal, without using a channel used to receive a signal of the terminal, resources do not need to be grouped or planned, and there is no need to strictly distinguish between different coverage mode sets or groups.
