METHODS AND EQUIPMENT FOR DIRECT CONNECTION INSTALLATION

Abstract

The invention proposes a method and apparatus for establishing a direct link, such that direct communication can be made between non-access point multi-link devices (non-access point multi-link devices, such as AP MLDs) and non-AP MLDs, or between station devices (sTAs) and non-AP MLDs, thereby improving data transmission efficiency. The invention is applicable to wireless connectivity (Wi-Fi) systems. The method is applied to the first device, and the second device comprises one or more STAs. The first device is connected to the third device, and the second device comprises multiple access points (APs). The second device is connected to the third device, and the second device comprises multiple STAs. When the first test device includes a single STA, the protected data is established using the address of the first device, the address of the second device, and the address of the first AP connected to the first device. When the first test device includes multiple STAs.The protected data is constructed using the address of the first device, the address of the second device, and the address of the third device. Therefore, the first device can transmit the first data unit through the direct link between the first and second devices, thereby increasing the data transmission speed.
