Multi-link operation method and device

The invention provides a multi-link operation (MLO) method and a device for the same, and the MLO method comprises the steps that a multi-chip controller of the device assigns different data to a plurality of chips of the device, and each chip corresponds to one link in multiple links; determining, using each chip, whether the assigned data satisfies a transmission failure condition; and in response to a first chip of the plurality of chips determining that the assigned data does not satisfy a transmission failure condition, the first chip transmitting the assigned data to an access point (AP). 本发明提供一种多链路操作(MLO)的方法以及用于多链路操作(MLO)的装置，其中MLO的方法包括：装置的多芯片控制器为所述装置的多个芯片指派不同的数据，其中每个芯片对应多链路中的一个链路；使用每个芯片确定所指派的数据是否满足传输失败条件；以及响应于所述多个芯片中的第一芯片确定所指派的数据没有满足传输失败条件，所述第一芯片向接入点(AP)发送所述所指派的数据。
