5 system reference model

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.

6 Media Access Control Layer Overview

6.1 Overview The MAC layer is used to manage and control the allocation and sharing of physical layer transmission resources among multiple users. The functional composition is shown in Figure 2. Definition of this standard The MAC layer has the following characteristics. --- The system adopts a centralized control architecture for multi-user scheduling; --- The system MAC layer provides connection-oriented services that support QoS for different priority services. Figure 2 MAC layer function composition 6.2 Adaptation sublayer The MAC layer is divided into an adaptation sublayer and a MAC sublayer. The adaptation sublayer uses the services provided by the MAC sublayer. Adapter sublayer completion The function is as follows. --- Receive SDU from the upper layer; --- classify the received upper SDUs; --- Send the PDU of the adaptation sublayer generated by this layer to the MAC sublayer; --- Receive the SDU of the adaptation sublayer in the peer entity. 6.3 Media Access Control Sublayer The basic functions of the MAC sublayer are divided into a management control plane and a data plane. The management control plane includes the following functions. a) System configuration. Manage system configuration messages and interact with the terminal to configure system configuration information. b) Radio resource management. mainly completes the service scheduling function, completes resource allocation based on service parameters and channel conditions, and has load Balance, access control and other functions. c) Network management. responsible for initializing and accessing the process, generating the messages required for the access process, including. access code selection, capability negotiation, and so on. 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; 3) Link adaptation. ---CQI measurement and feedback; ---MCS selection and feedback; --- Power control and management. The data plane includes the following functions. ---Automatic Request Retransmission (ARQ). acknowledgement and retransmission of MPDUs or fragmented/aggregated MPDUs of the MAC layer; ---Sharding/recombination. according to the scheduling result, the upper layer business data unit is fragmented and sent to the next processing module. Reassembling and recovering multiple fragments at the receiving end; ---MPDU generation. the upper layer service unit is encapsulated into a basic MAC frame, and then sent to the next processing module; ---MPDU aggregation. According to the scheduling result, the originating end performs aggregation operation on the upper layer service data unit.

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 exam......
