Problems solved by technology

[0003] The IEEE802.11X standard adopts the carrier sense / collision avoidance (Carrier Sense Multiple Access with Collision Avoidance, CSMA / CA) access method to simply reduce the cost of WiFi chips or devices, but CSMA / CA is not based on the physical layer (Physical Layer, PHY) is based on the multiple access mode of the Media Access Control (MAC) layer, resulting in no WiFi scheduling mechanism based on the PHY layer. Therefore, when multiple stations (Station, STA) have services at the same time, collisions will occur, resulting in downlink Bottleneck in data throughput of link (Downlink, DL) or uplink (Uplink, UL)
These bottlenecks lead to the inability of existing WiFi to provide high data throughput

Embodiment Construction

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0065] The technical solutions of the embodiments of the present invention can be applied to various WLAN systems.

[0066] It should be understood that in this embodiment of the present invention, for ease of description, the link from an AP to a STA is called a downlink, and the link from a STA to an AP is called an uplink, and the description of uplink and downlink should not be used in this embodiment of the present invention. The scope of protection constitu...

Abstract

The present invention discloses a method, AP, server and STA for cooperative transmission. The method includes: an AP receives an uplink preamble training sequence sent by a STA; the AP determines uplink quality information according to the uplink preamble training sequence; the AP sends the uplink quality information to a server, so that the server can perform the uplink quality information according to the uplink quality information. The road quality information determines the downlink cooperative transmission set. The method, AP, server, and STA for cooperative transmission in the embodiments of the present invention can implement cooperative transmission of multiple APs, thereby improving data throughput.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly, to a method, access point, server and station for cooperative transmission. Background technique [0002] With the popularization of various mobile, fixed, and handheld smart terminals, people's demand for mobile data will increase explosively in the future, resulting in both cellular networks and wireless local area networks (Wireless Local Area Network, WLAN). Network expansion and upgrading by means of new technologies and new solutions. Because the WLAN system uses unlicensed (Unlicensed) spectrum, it has the advantage of low cost. Although the WLAN system is suitable for indoor or hotspot scenarios, it has the disadvantages of poor mobility and serious interference. Wireless Fidelity (Wi-Fi) is still used as a WLAN. The vast number of operators, equipment manufacturers, enterprises and institutions are used as an important means of offloading indoor, hotspot, ente...
