Abstract

The invention discloses a superspeed wireless local area network frame polymerization device and a control method thereof. The device comprises a transmitting end and a receiving end, wherein the transmitting end comprises a frame format control unit and a transmitting unit; the receiving end comprises a receiving unit and a control command unit, and the control command unit controls a frame polymerization / segmentation mode and an access mode under different services and comprises an optimal frame format control module and a frame polymerization control command generation module; the optimal frame format control module receives real-time error rate information from the receiving unit, and compares the real-time error rate information with an error rate interval comparison table to select an optimal frame polymerization / segmentation mode and access mode; and according to the optimal frame polymerization / segmentation mode and access mode, the frame polymerization control command generation module generates a frame polymerization / segmentation control command for carrying out frame polymerization / segmentation control on the frame format control unit of the transmitting end. The method and the device provided by the invention can select proper polymerization modes and polymerization frame numbers in real time according to the service type and the error rate situation, and the wireless local area network is enabled to improve the throughput performance while satisfying time delay.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an ultra-high-speed wireless local area network frame aggregation device and a control method thereof. Background technique [0002] In 1990, the IEEE executive committee established the IEEE802.11 working group, which aims to create a wireless local area network (hereinafter referred to as WLAN) standard, and use it to solve compatibility issues between different WLAN devices. Referring to the 1SO seven-layer model, the IEEE802.11 series of specifications mainly formulate a series of specifications from two levels: the physical layer (hereinafter referred to as the PHY layer) and the media access control layer (hereinafter referred to as the MAC layer). The physical layer stipulates basic specifications such as wireless transmission signals. The media access control layer standard is some application requirement specification on the physical layer. At present, IE...
