Problems solved by technology

[0011] For method (1), only one STA can communicate at the same time, which is obviously not conducive to improving the throughput in the area; for method (2), for example, in 802.11n / ac technology, MU-MIMO (multi-user multi-input multi-output) to achieve directional transmission, but if there are devices of previous protocol versions such as 802.11a / b / g in the area, the channel may be preempted, resulting in the impact of 802.11n / ac devices data transmission

Abstract

The present invention provides a wireless communication method, comprising: generating a message frame, wherein the message frame includes a physical frame header part, a MAC frame part and a transmission identification bit, when the value of the transmission identification bit is a first value, it indicates the message The physical frame header part of the frame is transmitted by using an omnidirectional antenna, and the MAC frame part of the message frame is transmitted by using a directional antenna; the message frame is sent. The present invention also proposes a corresponding wireless communication device. Through the technical solution of the present invention, the physical frame header part and the MAC frame part of the message frame can be sent separately, so that on the one hand, the directional transmission of the message can be realized, which helps to improve the throughput in the area; The directional transmission STA can also learn the current channel occupancy by receiving the physical frame header part of the omnidirectional transmission, so as to avoid affecting the above-mentioned directional transmission process.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a wireless communication method and a wireless communication device. Background technique [0002] In WLAN technology, a message frame is mainly composed of a physical frame header part, a MAC (Medium Access Control, Media Access Control) frame part, and an actual data part to be transmitted. [0003] Due to the existence of multiple WLAN protocol standards, in order to support and be compatible with settings under various standards, multiple different modes have been established, so that there are multiple corresponding structures of message frames. [0004] 1) Non-high throughput mode (Non-HT) [0005] like Figure 1A As shown, the physical frame header part includes the original short training field (L-STF), the original long training field (L-LTF) and the original signal field (L-SIG), etc.; and the data field (DATA) contains the above MAC The frame ...
