Description

Information transmission method, communication device, and storage medium Technical Field The present application relates to the field of communications technologies, and in particular, to an information transmission method, a communications device, and a storage medium. Background A Basic Service Set (BSS) may include one Access Point (AP) and one or more non-access points (non-APs). Because the coverage areas of the AP and the non-AP are different, the AP and the non-AP may perceive different stations, and stations that cannot be perceived by the AP and the non-AP at the same time may be referred to as hidden stations. Taking an example that the hidden station is not perceived by the AP, and the hidden station is perceived by the non-AP, in the process that the hidden station communicates with other stations, the non-AP can detect that the hidden station communicates with other stations on a main channel, determine that the main channel is busy, and then the non-AP can jump to a non-main channel, and the AP cannot detect that the hidden station communicates with other stations on the main channel, determine that the main channel is idle, and then the AP can not jump to the non-main channel and still stay in the main channel. That is, if the AP and the non-AP sense different stations, the detection results of the channel states by the AP and the non-AP are inconsistent, and thus the channels where the AP and the non-AP reside are inconsistent, for example, the non-AP jumps to a non-primary channel, the AP does not jump to a non-primary channel, and still resides in the primary channel. However, in the process of communicating between the AP and the non-AP, if the channels where the AP and the non-AP reside are inconsistent, communication between the AP and the non-AP is likely to be confused, for example, transmission resources are not matched, and normal communication between the AP and the non-AP is not possible. Disclosure of Invention In order to solve the technical problems, embodiments of the present application provide an information transmission method, a communication device, and a storage medium, which can ensure normal communication between stations as much as possible. In a first aspect, an information transmission method is provided, where the method may be performed by a second site, or may be performed by a component of the second site, for example, a processor, a chip, or a system on a chip of the second site, or may be implemented by a logic module or software capable of implementing all or part of the second site. The following describes an example of this method performed by the second station. The information transmission method comprises the steps that a second station sends a trigger frame for triggering a first station to report a first message to the first station, so that the first station can report the first message, the second station receives the first message which comprises first information from the first station, and the first information is used for indicating whether the first station resides in a non-primary channel of the first station. In the information transmission method provided by the embodiment of the application, because the first message reported by the first station includes the information for indicating whether the first station resides in the non-main channel of the first station, the second station can clearly know the current channel of the first station through the message reported by the first station, so that the subsequent second station can allocate proper resources for the first station through the current channel of the first station, and further, the normal communication between the stations is ensured. With reference to the first aspect, in one possible implementation manner, in addition to the first information, the first message may further include other relevant information about the non-primary channel, for example, event information for indicating that the first station is triggered to jump to the non-primary channel, so that the second station can know, more clearly and comprehensively, through the first message, relevant information about the first station to jump to the non-primary channel. Based on the possible implementation manner, the subsequent second stations can allocate appropriate resources to the first stations through the clearer and comprehensive first message, so that normal communication between the stations is further ensured. With reference to the first aspect, in one possible implementation manner, the second information includes at least one of a bandwidth field, a length field, or a puncturing field, where the bandwidth field is used to indicate a bandwidth of the overlapping basic service set data triggering the first station to jump to the non-primary channel, or the bandwidth field is used to indicate a bandwidth indicated by the overlapping basic service set transmission opportunity triggering the first station to j
