Problems solved by technology

[0005] However, the outdoor wireless signal environment is changeable, and the dense distribution of WiFi devices leads to strong inter-device interference, which greatly reduces the transmission performance of WiFi devices, especially the outdoor uplink transmission will be seriously affected. Using the methods in the prior art, the uplink data transmission The reliability of the method is low, so the method in the prior art cannot guarantee the uplink transmission performance; furthermore, the retransmission probability is increased, and the uplink transmission efficiency is reduced

Embodiment Construction

[0143] Embodiments of the present invention provide an uplink transmission method, a station, an access point AP, a communication system, and a management entity, so as to improve uplink transmission performance.

[0144] The technical solution in the embodiments of the present invention is to solve the above-mentioned technical problems, and the general idea is as follows:

[0145] In the embodiment of the present invention, the station STA generates an uplink frame, and the uplink frame includes the robust uplink transmission RUT indication information. When the RUT indication information takes the first value, it indicates that the associated access point A-AP associated with the STA has cooperation with the A-AP. The cooperative access point C-AP of the relationship receives the uplink frame and performs RUT processing on the uplink frame; when the RUT indication information takes the second value, it means that only the associated access point A-AP associated with the STA ...

Abstract

The invention provides an uplink transmission method, a station, a communication system, and a management real object. The method comprises a step that a station STA generates an uplink frame which comprises RUT (robust uplink transmission) indication information. When the value of the RUT indication information is a first value, it indicates that an associated access point A-AP associated with the station STA and a coordinative access point C-AP in coordinative relation with the associated access point A-AP receive the uplink frame and carry out the RUT processing of the uplink frame; when the value of the RUT indication information is a second value, it just indicates that the associated access point A-AP associated with the station STA receives the uplink frame and carries out the non-RUT processing of the uplink frame. The method also comprises a step that the station STA transmits the uplink frame.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an uplink transmission method, a station, an access point AP, a communication system and a management entity. Background technique [0002] With the evolution of the WLAN (Wireless Local Area Networks; Wireless Local Area Network) standard, the current IEEE (Institute of Electrical and Electronics Engineers; Institute of Electrical and Electronics Engineers) 802.11 working group has begun to develop the next-generation WiFi (Wireless Fidelity; Wireless Fidelity) standard research and development work. The next-generation WiFi standard is referred to as HEW (High Efficiency WLAN; high-efficiency wireless local area network). The goal is to increase the system capacity to more than 10Gbps, paying special attention to carrier-grade WiFi (Carrier-grade WiFi) and high-density WiFi scenarios. [0003] The so-called carrier-grade WiFi refers to the situation where the Wi...
