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 invention provides a wireless communication method. The wireless communication method includes generating a message frame and sending the message frame. The message frame comprises a physical frame head portion, an MAC (medium access control) frame portion and a transmission identification position. As the transmission identification position is a first value, the physical frame head potion of the message frame employees the omnidirectional antenna transmission, the MAS frame portion employees directional antenna transmission. The invention further provides a wireless communication device. According to the technical scheme, the physical frame head portion and the MAC frame portion are separably transmitted, in this way, directional transmission of message is achieved to increase throughput capacity in the area; and by receiving the physical frame head portion of omnidirection transmission, the STA with directional transmission unsupported also learns the current channel occupation condition, accordingly avoiding influence to the directional transmission.

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] Such as 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 fra...
