The system reference model is shown in Figure 1. The main functions of each layer are as follows.
a) The MAC layer includes an adaptation sublayer and a MAC sublayer.
--- Adaptation sublayer. mainly provides mapping between external network data and this part of the MAC layer service data unit (MSDU)
And conversion functions;
---MAC sublayer. In addition to acting as a media access control function, it also includes management and control of the system and the PHY.
Support for specific features.
b) The PHY layer mainly provides a PHY transmitter that maps MAC layer protocol data units (MPDUs) to corresponding physical channels.
The system uses Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (MIMO) technologies.
The PICS for the MAC and PHY layers is shown in Appendix A.

d) QoS management. manages the QoS parameters of the service and maintains the establishment, modification and deletion of each service flow.
e) Power saving management. The STA that manages no service enters the sleep state, and returns from the sleep state to the active state.
f) PHY layer control, mainly including the following sub-functions.
1) Channel management. including channel switching, management spectrum measurement and message reporting;
2) MIMO management. channel detection mechanism to determine and select MIMO working mode determination and selection;

7 media access control frame format
7.1 Universal Media Access Control Frame Format
7.1.1 Overview of Universal Media Access Control Frame Formats
The frame format of the MAC Protocol Data Unit (MPDU) is shown in Figure 3. Each MPDU can be divided into three parts. The first part is
The fixed-length general MAC header; the second part is the payload carried by the MPDU; the third part is the verification (FCS) information.
All the fields in the MAC frame contain bits that are numbered from low to high and sent to the physical layer in descending order.
The bits within one byte are transferred to the physical layer in order from left (LSB) to right (MSB). The bits contained in the same field follow the low
The number order to the high corresponds to a decimal number, for example, b9~b11=000, corresponding to 0; b9~b11=001, corresponding to 4.
