As shown in FIG. 1A, the method for indicating the undesired working channel includes the following steps 110-130:

In step 110, an undesired working channel is determined, the undesired working channel being a channel that does not wish to operate due to intermodulation distortion.

In an embodiment of the present disclosure, the undesired working channel may refer to a channel in which the MBO-STA does not wish to operate on the channel because of intermodulation distortion (intermodulation distortion due to simultaneous transmission of multiple uplink frequency bands).

There are many methods for determining the undesired working channel by the MBO-STA, for example, determining an undesired working channel by using an interference judging algorithm, wherein the interference judging algorithm can adopt, but is not limited to, the following implementation manner: calculating the third-order harmonic according to the signal waveform A frequency band that may interfere.

In addition, there are many channels that can generate intermodulation distortion. For example, ISM (Industrial Scientific Medical) transmission operating at 2400-2420MHz may result in mutual interference for LTE (Long Term Evolution) downlink channel 2620-2640MHz. Adjust the interference.

In the embodiment of the present disclosure, the specific format of the non-preferred channel report attribute is as shown in Table 1.

Table 1

In an embodiment, there are many methods for generating an association request frame for indicating an undesired working channel, including but not limited to the following four modes:

The first way is to add first information in the non-preferred channel report attribute, the first information is used to indicate an undesired working channel that generates intermodulation distortion due to simultaneous transmission of multiple cellular network uplink frequency bands. For example, the first information is an identifier of an undesired working channel, and the first information is added to the channel list shown in Table 1.

In this manner, after the MBO-STA sends the association request frame after the first information is sent to the AP, the AP can learn the undesired working channel indicated by the MBO-STA from the first information, thereby avoiding allocating the MBO-STA. channel.

The second mode is: adding a first information and a second information to the non-preferred channel report attribute, where the first information is used to indicate an undesired working channel that generates intermodulation distortion due to simultaneous transmission of uplink frequency bands of multiple cellular networks, the second The information is used to indicate multiple cellular network bands that produce intermodulation distortion when operating simultaneously. For example, the first information is an identifier of an undesired working channel, and the second information is an identifier of a plurality of cellular network bands that generate intermodulation distortion, and the first information is added to the channel list shown in Table 1, and the second information is Information is added to the preferred classes shown in Table 1.

In this manner, after the MBO-STA sends the association request frame after adding the first information and the second information to the AP, the AP may learn the undesired working channel indicated by the MBO-STA from the first information, and may also obtain the second It is known in the information which cellular networks work together to generate intermodulation distortion, thereby avoiding assigning the MBO-STA to a channel in which intermodulation distortion occurs.

In a third mode, the first information and the third information are added to the non-preferred channel report attribute, where the first information is used to indicate an undesired working channel that generates intermodulation distortion due to simultaneous transmission of uplink frequency bands of multiple cellular networks, and the third Information for indicating that the MBO-STA does not wish to determine the undesired work letter due to intermodulation distortion Work on the road. For example, the first information is an identifier of an undesired working channel, the third information is an identifier of intermodulation distortion, and the first information is added to the channel list shown in Table 1, and the third information is added to Table 1. The reason in the code.

In this manner, after the MBO-STA sends the association request frame after adding the first information and the third information to the AP, the AP may learn the undesired working channel indicated by the MBO-STA from the first information, and may also obtain the third It is known in the information that the MBO-STA indicates the undesired working channel because intermodulation distortion is generated, thereby avoiding allocating the MBO-STA to a channel in which intermodulation distortion occurs.

The fourth mode is: adding first information, second information, and third information to the non-preferred channel report attribute, where the first information is used to indicate an undesired working channel that generates intermodulation distortion due to simultaneous transmission of uplink frequency bands of multiple cellular networks. The second information is used to indicate a plurality of cellular network frequency bands that generate intermodulation distortion when working simultaneously, and the third information is used to indicate that the MBO-STA does not wish to determine the undesired work due to intermodulation distortion. Working on the channel. For example, the first information is an identifier of an undesired working channel, the second information is an identifier of a plurality of cellular network bands that generate intermodulation distortion, and the third information is an identifier of intermodulation distortion, and the first information is added to Table 1. In the illustrated channel list, the second information is added to the preferred class shown in Table 1, and the third information is added to the reason code shown in Table 1.

In this manner, after the MBO-STA sends the association request frame after adding the first information, the second information, and the third information to the AP, the AP may learn the undesired working channel indicated by the MBO-STA from the first information, and It can be learned from the second information which cellular networks generate intermodulation distortion when working at the same time, and can also learn from the third information that the reason that the MBO-STA indicates the undesired working channel is that intermodulation distortion is generated, thereby avoiding the MBO- The STA allocates a channel in which intermodulation distortion occurs.

In step 230, the association request frame is sent to the AP through the unlicensed frequency band in the MBO protocol, so that the AP determines the undesired working channel indicated by the MBO-STA according to the information added in the association request frame.

In this embodiment, through the foregoing steps 210-step 330, the MBO-STA may determine one or more undesired working channels, and generate an association request frame for indicating an undesired working channel and related information, thereby passing the non-authorization in the MBO protocol. The frequency band sends the generated association request frame to the AP. Through the above process, the MBO-STA can also accurately indicate to the AP that the channel does not work due to intermodulation distortion, so that the AP can avoid configuring the undesired working channel when configuring the working channel for the MBO-STA, thereby avoiding intermodulation distortion. The adverse effects also increase the channel utilization of the MBO-STA.
