Description

Information transmission method, electronic device and storage medium Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to an information transmission method, electronic device, and storage medium. Background Art

[0002] Fiber to the Room (FTTR) technology uses optical fiber to connect wireless access points (APs) in different rooms or locations in homes, small and medium-sized enterprises, and other scenarios. This technology provides high-bandwidth, highly reliable connections between multiple APs. A point-to-multipoint optical distribution network can be used to connect master and slave APs. With the advancement of wireless communication technology, energy conservation has become a key requirement. Current research directions for AP-side energy conservation mechanisms include: 1. Dynamic Access Point Power Save (Dynamic AP PS), which uses trigger frames to dynamically adjust the AP's transmit and receive antennas; 2. Scheduled AP Power Save (Scheduled AP PS), which uses periodic AP sleep counts to wake up the AP during service periods and sleep outside of service periods; and Unscheduled AP Power Save (Unscheduled AP PS), which requires a trigger frame to wake the AP after it enters sleep mode. With the development of wireless communication, multi-link operation (MLO) has become a mandatory feature on the AP side, and multi-link devices (MLD) will become a key product form factor on the AP side.However, when a sub-access point in the AP MLD enters energy-saving mode, it may not be able to exchange frames or may only be able to exchange frames in a restricted manner (for example, a scheduled / unscheduled AP PS cannot exchange frames after entering the doze state; for example, a dynamic AP PS can only exchange specific initialization control frames after entering the energy-saving state). Therefore, before the AP is about to enter energy-saving mode, the station (STA) on the current link and the STAs on other links cannot obtain relevant information about the AP's energy-saving mode. After the AP enters energy-saving mode, the STAs on other links cannot obtain the energy-saving state and energy-saving mode of the AP through the RNR element in the beacon or probe response sent by the corresponding AP. The STAs on other links cannot obtain the specific energy-saving information of the AP through the multi-link probe response sent by the AP. If the current link is in energy-saving state, when a non-AP MLD discovers and associates to the link through other links of the AP MLD or is newly associated to the link through multi-link reconfiguration, the non-AP STA on the link cannot communicate with the AP normally. Therefore, when the AP Before an MLD link enters energy-saving mode or while in energy-saving mode, other links of the AP MLD must notify the link's energy-saving information. This information is obtained before a non-AP MLD link is associated with the link. This can cause frame exchange failures or other communication problems on the non-AP MLD side.

STA1 in the non-AP MLD may not send a probe request or restrictively request detailed energy-saving information of AP1, or STA2 may send a multi-link probe request to request detailed energy-saving information of AP1. After receiving the restrictive send request from STA1, AP1 includes detailed energy-saving information of AP1 in the AP PS Info of the common info in the basic multi-link element, or in other independent elements in the restrictive response it sends.

The non-AP MLD uses the received AP energy-saving information as a basis for subsequent multi-link association link determination. If the non-AP MLD determines that the energy-saving operation of the current link will not affect the subsequent communication needs of the non-AP MLD and the AP MLD, it may select the link as a link for subsequent association requests. Otherwise, it may not select the link as a link for association requests.
