Problems solved by technology

The disadvantage of this mechanism is that it needs to consume additional time resources and spectrum resources
At the same time, due to the time division multiplexing mechanism of the existing wireless LAN, only one STA and AP share the same communication at the same time.
Although the latest IEEE 802.11ac standard supports the downlink multi-user transmission mechanism, it can only support the AP to communicate with multiple STAs at the same time, and cannot realize direct communication between multiple STAs

Embodiment Construction

[0033] Taking the millimeter wave wireless local area network (IEEE 802.11aj) as an example, the specific implementation manner of a power-saving polling frame format and the transceiver device of the present invention will be further described in detail with reference to the accompanying drawings. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, modifications to various equivalent forms of the present invention by those skilled in the art all fall within the appended rights of this application.

[0034] In the embodiment of the present invention, the node pair (A1, A2), (B1, B2), (C1, C2) are mutually hidden node pairs, see image 3 . Initiating sites are A1, B1, and C1, and their corresponding responding sites are A2, B2, and C2, respectively. The Capability field for these sites (see Figure 4 ) in the S2SSupport subfield i...

Abstract

The invention belongs to the technical field of wireless communication systems, and discloses an S2S communication method based on hidden node pairs. The access point AP sets the content of the S2SAnnouncement frame according to the information of the hidden node pair in the BSS and broadcasts the S2SAnnouncement frame; after the notified originating station STA receives the S2SAnnouncement frame, it directly initiates communication transmission to the target STA, and the communication between the initiating STA and the target STA Direct communication must be completed within the Duration. The present invention proposes an S2S communication mechanism based on hidden node pair information, and designs an S2SAnouncement function frame format, so that multiple pairs of sites can communicate directly at the same time, improving system throughput.

Description

technical field [0001] The invention relates to an S2S communication method based on a hidden node pair, and belongs to the technical field of wireless communication systems. Background technique [0002] With the increasing scarcity of wireless communication spectrum resources and the demand for ultra-high-speed data transmission rates, the development of ultra-high-speed wireless communication technology in the millimeter wave band has attracted more and more attention, and has become one of the most potential technologies in future wireless communication technologies. [0003] The 45GHz frequency band MIMO (Multiple Input Multiple Output) wireless millimeter wave communication technology for ultra-high-speed wireless access can realize ultra-high-speed wireless transmission above 10Gbps between devices. Compared with the low-frequency band, the millimeter wave has the following characteristics: first, the available spectrum range is wide and the channel capacity is large;...
