Problems solved by technology

[0005] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: one of the STA and the AP, such as the AP, must switch the smart antenna to a directional direction when there is a need for data transmission and needs to compete for the channel to orientate In the process of listening to the channel and backing off, the other party of the STA and the AP, such as the STA, is likely to send data to the AP in other directions of the smart antenna, because the smart antenna of the AP at this time is the directional direction, therefore, the AP cannot receive the data sent by the STA through other directions of the smart antenna, resulting in data loss

Embodiment 1

[0050] Embodiment 1 corresponds to service scenario 1. Both STAs supporting time division and STAs not supporting time division are connected to the AP. For ease of understanding, the processes in which the AP and the STA use smart antennas to transmit data respectively are described in the same process.

[0051] see image 3 In Embodiment 1 of the present invention, the process of data transmission between the AP and the STA using the smart antenna may include the following steps:

[0052] Step 301: The STA and the AP perform time division capability negotiation, and the AP determines that both STAs supporting time division and STAs not supporting time division are connected to the AP.

[0053] The time-division capability negotiation can be carried out by carrying the time-division capability bit to inform the AP whether it supports the time-division transmission function when the terminal makes a detection or association request. At the same time, the AP also carries the tim...

Embodiment 2

[0080] Embodiment 2 corresponds to service scenario 2, and only STAs that do not support time division are connected to the AP. For ease of understanding, the processes in which the AP and the STA use smart antennas to transmit data respectively are described in the same process.

[0081] see Figure 5 In Embodiment 2 of the present invention, the process of data transmission between the AP and the STA using the smart antenna may include the following steps:

[0082] Step 501: The STA and the AP perform time division capability negotiation, and the AP determines that only STAs that do not support time division are connected to the AP.

[0083] Step 502: The AP periodically divides the transmission cycle of the channel, and divides the downlink transmission phase and the uplink transmission phase corresponding to the terminal's time division capability. The uplink transmission phase is actually a competition phase used by STAs that do not support time division.

[0084] In th...

Embodiment 3

[0091] Embodiment 3 corresponds to service scenario 3, and only STAs supporting time division are connected to the AP. For ease of understanding, the processes in which the AP and the STA use smart antennas to transmit data respectively are described in the same process.

[0092] see Figure 7 In Embodiment 3 of the present invention, the process of data transmission between the AP and the STA using the smart antenna may include the following steps:

[0093] Step 701: The STA and the AP perform time division capability negotiation, and the AP determines that only STAs that support time division can access the AP.

[0094] Step 702: The AP periodically divides the transmission cycle of the channel, and divides the downlink transmission phase and the uplink transmission phase corresponding to the time division capability of the terminal. The uplink transmission phase is actually the uplink allocation phase used by STAs supporting time division.

[0095] In the third embodiment...

Abstract

The invention provides a data transmission method, access point equipment and a terminal. The method comprises the following steps: dividing the transmission period of a channel into a descending transmission stage and an ascending transmission stage corresponding to terminal time division capability; in the ascending transmission stage, receiving ascending data according to the terminal time division capability corresponding to the ascending transmission stage; in the descending transmission stage, adjusting the wave beam of a smart antenna; and directionally sending descending data. The access point equipment provided by the invention comprises an ascending and descending stage division module, an ascending receiving and processing module and a descending sending and processing module. The terminal provided by the invention comprises an ascending sending and processing module and a descending receiving and processing module.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a data transmission method, an access point device, and a terminal. Background technique [0002] In the traditional wireless local area network (Wireless LAN, hereinafter referred to as "WLAN") technology, terminals (Station, STA) and access points (Access Point, AP) support omnidirectional antenna technology, using omnidirectional antennas for data transmission, so This leads to problems such as poor penetration of WLAN signals, dead angles, and large interference within and between WLAN systems. In order to overcome these problems, smart antenna technology is introduced into the WLAN system. STAs and APs support smart antenna technology and use smart antennas for data transmission. [0003] The smart antenna in the WLAN system uses beam switching antenna technology to generate multiple narrow beams with different directions within the coverage area. Whe...
