- the MPDU1 to the MPDU5 are both It is an unfragmented MPDU; MPDU 61 is a fragmented MPDU.
- the first encapsulated MPDU may be an unfragmented MPDU or a fragmented MPDU (for example, the last encapsulated MPDU61 when the G-MPDU was last encapsulated, the next time the G-MPDU is encapsulated)
- the first package will be MPDU62).
- the encapsulated MPDU may be set for the MPDU of the fragment, so that the peer can recover the unresolved Slice of MPDU.

- the flow identifier is used to identify a flow, including a management control flow and a data flow, and the data flow is divided into multiple data flows according to a service type.
- the retransmission indication is used to indicate whether the data is retransmitted. For example, if the current frame is a retransmission frame of the previous frame, this field is set to 1; otherwise, it is set to 0.
- the fragment number (FSN) is used to indicate the number of each fragment in the MPDU of the same sequence number.
- the sequence number (SN) is used to indicate the number of each MPDU.
- the fragment indication is used to indicate whether there is a fragment of the current MPDU later.
- the length is used to indicate the total byte length of all fields between the MAC header field and the FCS field.
- each MPDU is encapsulated into a subframe of a G-MPDU, and one or more of the subframes constitute a G-MPDU.
- the MPDU may be an unfragmented MPDU or a fragmented MPDU.
- the sub-frame for encapsulating each MPDU as a G-MPDU includes: setting a delimiter before the MPDU; setting a padding bit after the MPDU, so that the length of the sub-frame is an integer multiple of 2 bytes .

- the data receiving method provided by the embodiment of the present invention is used in combination with the data sending method to parse the sent G-MPDU, reassemble the obtained MPDU of the fragment, and recover the unfragmented MPDU. Since the G-MPDU performs fragmentation only when the remaining length is insufficient to encapsulate a complete MPDU, most of the unresolved MPDUs are not fragmented during the parsing process, and the overall data is not required. Transmission efficiency is high.
- Step S801 After the MPDU is parsed, the flow identifier FID is obtained. The unfragmented MPDU is placed in the buffer window corresponding to the FID; the fragmented MPDU is placed in the fragment buffer corresponding to the FID, and the MPDU of the fragment of the same sequence is reassembled, and the recovered unresolved After the MPDU of the slice, the MPDU is placed in the buffer window; Step S802: The MPDU buffered in the buffer window is sent to the upper layer.
