With the development of wireless communication technology, the integration of terminal equipment is getting higher and higher. A terminal device often supports multiple wireless communication protocols, integrates multiple wireless communication modules and simultaneously accesses multiple wireless networks, such as WLAN, LTE, BT and GNSS. Multiple communication protocols communicating simultaneously may interfere with each other, resulting in communication failure or performance loss. When the communication frequency bands of different communication systems are adjacent, the sending operation of one communication system will interfere with the receiving operation of another system. For example, Wi-Fi is adjacent to the LTW Band 40 and LTE Band 7 bands. When the frequency components fall into the adjacent channel working bands, it will cause communication interference in the adjacent channels. In addition, when multiple wireless communication modules exist at the same time, the physical interval between the RF modules of each communication module is relatively small. When working at the same time, there is mutual interference between the communication systems, which affects the sending and receiving of each communication module. In addition, with the increase in the bandwidth of the wireless communication system and the continuous enrichment of the bandwidth, the interference problem of multiple wireless communications in the device becomes more serious, and the reliability of data transmission between devices is reduced.

For example, when the non-AP MLD enables the Enhanced Multi-Link Single Radio (EMLSR) link, the STA working on the EMLSR link and attached to the non-AP MLD enters the listening operation and the mode of receiving the initial control frame sent by the AP MLD. When the STA working on the EMLSR link and attached to the non-AP MLD has in-device coexistence activities, such as P2P communication or BT communication, the EMLSR operation mode may fail to be enabled or the initial control frame sent by the AP MLD may not be received, resulting in communication interruption or data packet loss. Alternatively, during data communication between the STA and its associated AP, the in-device interference generated by the BT communication service of the STA or the communication in the frequency bands such as LTE Band 40 and LTE Band 7 may cause the Wi-Fi data packet loss or even communication interruption of the STA and the AP.

To solve the above problems, the technical solutions in the embodiments of the present disclosure will be further described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or part of the subject, but are not limited thereto. The subjects shown in FIG1 are examples, and the communication system may include all or part of the subjects in FIG1 , or may include other subjects other than FIG1 , and the number and form of each subject are arbitrary, and each subject may be physical or virtual, and the link relationship between the subjects is an example, and the subjects may be linked or not linked, and the link may be in any manner, and may be a direct link or an indirect link, and may be a wired link or a wireless link.

The embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as IEEE 802.11 system standards, such as 802.11a/b/g standards, 802.11n standards, 802.11ac standards, 802.11ax standards, 802.11bf, 802.11be standards, or their next generation, such as 802.11bn.

FIG2 is an interactive schematic diagram of a communication method shown in an embodiment of the present disclosure. The communication method shown in FIG2 includes:

S21. The STA sends a first radio frame, where the first radio frame includes a first information field. The first information field is used to indicate that in-device co-existence interference exists in the STA.

In some embodiments, the first radio frame may include a first information field, where the first information field is used to indicate that there is in-device co-existence interference between the STA and the device.

In some embodiments, the first wireless frame includes a channel usage Channel Usage element, the channel usage Channel Usage element includes a usage mode Usage Mode field, when the identification value of the usage mode Usage Mode field is a first value, the usage mode Usage Mode field is a first information field, that is, when the identification value of the usage mode Usage Mode field is a first value, the usage mode Usage Mode field is used to indicate that the STA has in-device co-existence interference.

As an example, the indication method of the Usage Mode field may be as shown in the following table:

When the identification value of the Usage Mode field is 0, the Usage Mode field is used to indicate the Noninfrastructure BSS wireless network mode. When the identification value of the Usage Mode field is 5-254, the Usage Mode field is a reserved bit. When the identification value of the Usage Mode field is 255, the Usage Mode field is used to indicate an unknown request. If the first value is 4, and the identification value of the Usage Mode field is 4, the Usage Mode field is used to indicate in-device coexistence activities (In-device Coexistence Activities), that is, to indicate that the STA has in-device coexistence interference.

It should be noted that the first value of 4 is only an example, and may be any value between 5 and 254, which is not limited here.

In some embodiments, the first radio frame may further include a second information field, where the second information field is used to indicate a resource unit RU where in-device coexistence interference exists for the STA, that is, used to indicate a RU when the STA performs an in-device coexistence activity.

For example, when the first radio frame indicates that the STA has in-device co-existence interference through the first information field, the first radio frame also includes a second information field, and indicates the RU of the in-device co-existence interference of the STA through the second information field.

In some embodiments, the second information field may be a target wake time (TWT) element field.

In some embodiments, the second information domain includes at least one TWT element, and each TWT element corresponds to a TWT service period (Service Period, SP).

Each TWT element includes at least one item from the first sub-information and the second sub-information fields.

Among them, the first sub-information field in each TWT element is used to indicate the first RU of the STA that has in-device coexistence interference in the TWT SP corresponding to the corresponding target wake-up time element (TWT element), that is, it is used to indicate the first RU used by the STA when performing in-device coexistence activities in the TWT SP corresponding to the corresponding TWT element.

Among them, the second sub-information field in each TWT element is used to indicate that in the TWT SP corresponding to the corresponding TWT element, the first RU of the STA where there is in-device coexistence interference is in an unavailable state (Unavailability Mode).

As an example, each TWT element includes a first sub-information field, and the first sub-information field is used to indicate that the STA has a first RU of intra-device coexistence interference within the TWT SP corresponding to the TWT element.

As an example, each TWT element includes a second sub-information field, and the second sub-information field is used to indicate that within the TWT SP corresponding to the TWT element, the first RU of the STA where there is in-device coexistence interference is in an unavailable state.

In some embodiments, the second information field includes at least one TWT element, each TWT element includes a target wake-up time parameter set (Individual TWT Parameter Set) field, and the target wake-up time parameter set (Individual TWT Parameter Set) field includes a first sub-information field.

Optionally, the first information field may be a resource unit index (RU Index) field,

Optionally, the first information field can be a reserved bit in the target wake-up time parameter set (Individual TWT Parameter Set) field, or it can be shared with other information in the target wake-up time parameter set (Individual TWT Parameter Set) field, such as sharing a 1-byte length with the target wake-up time channel (TWT Channel) field in the target wake-up time parameter set (Individual TWT Parameter Set) field.

As an example, the format of the Individual TWT Parameter Set field may be as follows:

In some embodiments, the second information field includes at least one TWT element, each TWT element includes a control field, and the control field includes a second sub-information field.

The content of the first wireless frame is exemplarily described below with reference to specific examples.

The first wireless frame includes a channel usage Channel Usage element, and the channel usage Channel Usage element includes a usage mode Usage Mode field. When the identification value of the usage mode Usage Mode field is the first value, the usage mode Usage Mode field is the first information field, that is, it is used to indicate that the STA has in-device co-existence interference.

And/or, after receiving the first wireless frame, the AP can determine that the first RU in which the STA has in-device coexistence interference in each TWT SP is in an unavailable state, such as determined based on the second sub-information field in each TWT element.
