Embodiment 1

[0044] Please refer to Figure 7 And other drawings, a method for direct communication between stations in a wireless local area network, comprising:

[0045] The first station generates a frame including the first high-efficiency signaling;

[0046] The first station configures the SU / MU indication information in the first high-efficiency signaling as SU, and configures the UL / DL indication information in the first high-efficiency signaling as DL;

[0047] The first station sends a frame including the first high-efficiency signaling ( Figure 7 Step S10 in ).

[0048] Further, the first station generates a MAC header field, the first station configures the To DS field in the MAC header field as "0", and the first station configures the From DS field as "0" .

[0049] The first station sends the MAC header field.

[0050] In another aspect, a method for direct communication between stations in a wireless local area network is provided, including

[0051] The second stati...

Embodiment 2

[0063] A method for sending an indication of a direct communication link data packet between stations in a wireless local area network is provided:

[0064] The first station generates first efficient signaling.

[0065] The first station configures the SU / MU indication information in the first high-efficiency signaling as SU, and configures the UL / DL indication information in the first high-efficiency signaling as DL;

[0066] The first high-efficiency signaling includes DSSL indication information, which is used to indicate that the currently sent data transmission is DSSL transmission.

[0067] The first station generates and sends the first high-efficiency signaling

[0068] The second station receives and reads the first efficient signaling.

[0069] The second station reads the SU / MU indication information of the first high-efficiency signaling as SU. It is judged that the currently received data transmission is SU transmission.

[0070] The second station reads the ...

Abstract

The invention discloses a method for direct communication between stations in a wireless local area network and related stations. The method for direct communication between stations in a wireless local area network includes: a first station sends a data frame to a second station; the data frame includes a first high-efficiency A signaling field, the first high-efficiency signaling field includes first indication information used to indicate that the data frame is a single user (SU) data frame and the first indication information used to indicate that the data frame is a downlink (DL) data frame 2. Instructions.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method for direct communication between stations in a wireless local area network and related equipment. Background technique [0002] Wireless Local Area Networks (WLAN for short) is a network system that uses radio frequency technology to transmit data in the air. With the widespread application of smart terminals, people's demand for data network traffic is increasing day by day, and carrying these traffic through WLAN has become one of the very important information data transmission methods. [0003] The development of WLAN technology is inseparable from the formulation and promotion of its standards. Among them, the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, referred to as: IEEE) 802.11 series is the main standard of WLAN, and has successively experienced 802.11, 802.11b / g / a, 802.11n, 802.11ac ...
