The embodiment of the application provides a multi-band indication method, which comprises the following steps: a first communication device generates a first frame, the first frame comprising: a first operation level field, where when a basic service set BSS established by the first communication device operates in a first frequency band and a second frequency band simultaneously, the first operation level field is used to indicate a start frequency point of the second frequency band, the first frequency band is a frequency band including a main channel, and the second frequency band is a frequency band not including the main channel; the first communication device transmits the first frame.

摘要：【中文】本申请公开了一种多频段传输方法及装置，用以利用多频段并行传输提高业务的业务数据的传输效率。该方法包括：接收端通过M个频段从发送端并行接收数据包，M个频段承载的数据包属于同一业务流；接收端从发送端接收BAR，BAR携带SSN，BAR用于请求发送端在第m个频段上发送的数据包的接收状态；接收端将SN在SSN之前的未接收到的数据包标记为第m状态；接收端判断是否存在一个或多个未接收到的数据包被标记为第1状态、第2状态、…、第M状态，若是，接收端将一个或多个未接收到的数据包标记为丢弃状态；接收端判断是否存在SN连续的数据包；若是，接收端递交SN连续的数据包中的状态为接收状态的数据包。 【EN】The application discloses a multi-band transmission method and a multi-band transmission device, which are used for improving the transmission efficiency of service data of a service by utilizing multi-band parallel transmission. The method comprises the following steps: a receiving end receives data packets in parallel from a sending end through M frequency bands, wherein the data packets borne by the M frequency bands belong to the same service flow; the receiving end receives a BAR from the sending end, wherein the BAR carries SSN and is used for requesting the receiving state of a data packet sent by the sending end on the mth frequency band; the receiving end marks the data packet which is not received before the SSN by the SN as the m-th state; the receiving end judges whether one or more unreceived data packets are marked as a1 st state, a2 nd state, … th state and an Mth state, if so, the receiving end marks the one or more unreceived data packets as a discarding state; the receiving end judges whether data packets with continuous SN exist or not; if yes, the receiving end submits the data packet of which the state is the receiving state in the data packets with continuous SN.
