Problems solved by technology

However, for different transmission requirements or transmission scenarios, the master AP uses signaling in different frame formats to schedule the slave APs to meet the transmission requirements, which may lead to complex signaling design, inflexible scheduling, and high complexity in receiving from the AP.

Abstract

The embodiment of the invention discloses an information transmission method, an information receiving method and device for a wireless communication system, which are used for providing a scheme suitable for flexibly scheduling slave APs in a unified frame format in a multi-AP cooperative transmission scene. The embodiment of the invention provides an information transmission method. The method comprises the following steps that a first access point AP generates a slave trigger frame, wherein the slave trigger frame comprises trigger type information and AP indication information, the triggertype information is used for indicating the type of the slave trigger frame, the AP indication information comprises an identifier of a second AP, the identifier of the second AP is used for indicating the second AP, the slave trigger frame is used for triggering the second AP to send a physical layer protocol data unit (PPDU), and the PPDU bears a frame corresponding to the type of the slave trigger frame; and the first AP sends the slave trigger frame to the second AP.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an information transmission method, an information receiving method and a device for a wireless communication system. Background technique [0002] In the current wireless communication system, a larger bandwidth (such as 320MHz) and more stream numbers (such as 16 spatial streams) can be introduced in an extremely high throughput (EHT) to improve the throughput of the communication system volume and transfer efficiency. For example, in the EHT, it is necessary to increase the spatial streams (such as 16 spatial streams) to improve the throughput. However, limited by device capabilities, it is generally difficult for a single access point (access point, AP) to provide 16 spatial streams. [0003] In a scenario where multiple APs are used for collaborative transmission, for example, distributed multiple-input multiple output (D-MIMO) can be used to achieve a ...
