Description

Technical Field

[0001] The present invention relates to the field of wireless communication, and particularly to a method for information transmission, an electronic device, and a storage medium. Background Art

[0002] Fiber to the Room (FTTR) technology connects wireless access points (APs) in different rooms or locations in scenarios such as homes or small and medium-sized enterprises through optical fibers, which can provide high-bandwidth and highly reliable connections for networking between multiple APs. The point-to-multipoint optical distribution network can be used to connect the master control AP and the slave APs. With the development of wireless communication technology, energy-saving requirements have gradually become an important prerequisite for current development. Currently, the energy-saving mechanisms on the AP side have the following research directions: 1. Dynamic Access Point Power Save (Dynamic AP PS) dynamically adjusts the transceiver antennas on the AP side through trigger frames; 2. Scheduled AP PS wakes up the AP during the service cycle through periodic sleep counting on the AP side and puts the AP to sleep outside the service cycle; Unsheduled AP PS wakes up the AP through trigger frames after the AP enters the sleep state. With the development, Multi-Link Operation (MLO) has become an essential function on the AP side, and Multi-Link Devices (MLDs) will become an important product form on the AP side. However, when a sub-access point in an AP MLD enters the energy-saving mode, frame exchange may not be possible or only restricted frame exchange can be performed (for example, frame interaction is not possible when scheduled / unscheduled AP PS enters the doze state; only specific initialization control frame interaction is possible when dynamic AP PS enters the energy-saving state); therefore, before the AP is about to enter the energy-saving mode, the stations (STAs) on the current link and the STAs on other links cannot obtain information about the AP's energy-saving mode; after the AP enters the energy-saving mode, the STAs on other links cannot learn about the AP's energy-saving state and energy-saving mode through the RNR element in the beacon or probe response sent by the corresponding AP; the STAs on other links cannot obtain specific energy-saving information about the AP through the Multi-link probe response sent by the AP. If the current link is in the energy-saving state, when a non-AP MLD discovers and associates with this link through other links of the AP MLD or newly associates with this link through ML reconfiguration, the non-AP STAs on this link cannot communicate with the AP normally; therefore, before and during the energy-saving mode of a certain link of the AP MLD, the other links of the AP MLD need to announce the energy-saving related information of this link, and the non-AP MLD needs to learn about the link energy-saving information in advance before association, resulting in frame interaction failures or other communication problems on the non-AP MLD side. Summary of the Invention

[0003] The embodiments of the present application aim to provide an information transmission method, an electronic device, and a storage medium to achieve energy-saving information transmission for multi-link device sub-access points, reduce the frame interaction failure probability on the non-access point multi-link device side, and thus improve the communication quality.
