AI Technical Summary

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 IEEE802.11ac 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

Abstract

The invention belongs to the technical field of a wireless communication system, and discloses a hidden node pair based S2S (Station to Station) communication method. The hidden node pair based S2S communication method comprises the steps that an access point AP sets content of a S2SAnnoucement frame based on information of a hidden node pair in the BSS (Basic Service Set) and broadcasting as well as sending the S2SAnnoucement frame; and a notified initiating station STA after receiving the S2SAnnoucement frame directly initiates communication transmission to a target STA (Station), wherein direct communication between the initiating STA and the target STA must be finished within the Duration. An S2S communication mechanism is provided based on the hidden node pair information, and the S2SAnnoucement functional frame format is designed, so that direct communication can be carried out synchronously between multiple pairs of stations, and the system throughput is increased.

Description

Technical field [0001] The invention relates to an S2S communication method based on hidden node pairs, 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 frequency band has attracted more and more attention and has become one of the most promising technologies in future wireless communication technologies. [0003] The 45GHz band multiple input multiple output (MIMO: Multiple Input Multiple Output) wireless millimeter wave communication technology for ultra-high-speed wireless access can realize ultra-high-speed wireless transmission of more than 10Gbps between devices. Compared with low frequency bands, millimeter wave has the following characteristics: First, the usable spectrum range is wide, and the chann...
