[0117] With the advancement of wireless communication technology, terminal devices are becoming increasingly integrated. A single 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. Simultaneous communication of multiple communication protocols can interfere with each other, leading to communication failures or performance loss. When different communication systems operate in adjacent frequency bands, the transmission of one system can interfere with the reception of another. For example, Wi-Fi, LTW Band 40, and LTE Band 7 are adjacent frequency bands. When frequency components fall within the operating bands of adjacent channels, this can cause interference between adjacent channels. Furthermore, when multiple wireless communication modules coexist, the physical separation between the RF modules of each communication module is relatively small. When these modules operate simultaneously, interference between the communication systems can occur, impacting the transmission and reception of each module. Furthermore, as the bandwidth of wireless communication systems increases and becomes increasingly abundant, the problem of interference between multiple wireless communications within a device becomes increasingly severe, reducing the reliability of data transmission between devices.

[0118] 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 receives the initial control frame mode 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 BT communication service of the STA or the in-device interference generated by the communication in frequency bands such as LTE Band 40 and LTE Band 7 may cause the Wi-Fi data packet loss or even communication interruption between the STA and the AP.

[0119] To address the above issues, the following will further describe the technical solutions in the embodiments of the present disclosure in a clear and complete manner with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure and do not constitute all the embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort shall fall within the scope of protection of the present disclosure.

[0120] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0121] As shown in FIG. 1 , a communication system 100 includes a STA 101 and an AP 102 .

[0122] STA101 may be an independent STA, such as a non-EHT STA, or an attached STA of a Non-AP MLD; AP102 may be an independent AP, such as a non-EHT AP, or an attached AP of an AP MLD, and there is no limitation here.

[0123] In some embodiments, STA 101 and AP 102 may be terminal devices or network devices with Wi-Fi chips.

[0124] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field 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.

[0125] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or a portion of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The link relationships between the entities are illustrative only. The entities may be linked or unlinked, and the links may be of any type, including direct or indirect, wired or wireless.

[0126] The various embodiments of the present disclosure may be applied to wireless local area networks (WLANs), such as IEEE 802.11 system standards, such as 802.11a / b / g, 802.11n, 802.11ac, 802.11ax, 802.11bf, 802.11be, or their successors, such as 802.11bn. Alternatively, the various embodiments of the present disclosure may also be applied to wireless local area network systems, such as Internet of Things (IoT) networks or Vehicle to X (V2X) networks. Of course, the embodiments of the present disclosure can also be applied to other possible communication systems, such as long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), world-wide interoperability for microwave access (WiMAX) communication system, and future fifth generation (5G) communication system.

[0127] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. The communication method shown in FIG2 includes:

[0128] 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 coexistence interference exists for the STA.

[0129] In some embodiments, the first radio frame may include a first information field, where the first information field is used to indicate that in-device coexistence interference exists for the STA.

[0130] 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 coexistence interference.

[0131] As an example, the indication method of the Usage Mode field can be shown in the following table:

[0132] When the Usage Mode field's identifier value is 0, the Usage Mode field is used to indicate the noninfrastructure BSS wireless network mode. When the Usage Mode field's identifier value is 5-254, the Usage Mode field is reserved. When the Usage Mode field's identifier value is 255, the Usage Mode field is used to indicate an unknown request. If the first value is 4, and the Usage Mode field's identifier value 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.

[0133] 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.

[0134] 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, to indicate the RU when the STA performs an in-device coexistence activity.

[0135] For example, when the first radio frame indicates that the STA has in-device coexistence interference through the first information field, the first radio frame also includes a second information field, and indicates the STA through the second information field the RU of the in-device coexistence interference.

[0136] In some embodiments, the second information field may be a target wake time (TWT) element field.

[0137] In some embodiments, the second information field includes at least one TWT element, and each TWT element corresponds to a TWT service period (SP).

[0138] Each TWT element includes at least one item from the first sub-information and second sub-information fields.

[0139] 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 within 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 within the TWT SP corresponding to the corresponding TWT element.

[0140] The second sub-information field in each TWT element is used to indicate that within the TWT SP corresponding to the corresponding TWT element, the first RU of the STA with in-device coexistence interference is in an unavailable state (Unavailability Mode).

[0141] As an example, each TWT element includes a first sub-information field, where the first sub-information field is used to indicate to the STA that there is a first RU of in-device coexistence interference within the TWT SP corresponding to the TWT element.

[0142] 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 with in-device coexistence interference is in an unavailable state.

[0143] 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.

[0144] Optionally, the first information field may be a resource unit index (RU Index) field.

[0145] 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.

[0146] As an example, the format of the Individual TWT Parameter Set field may be as follows:

[0147] The target wake-up time parameter set (Individual TWT Parameter Set) field includes the TWT Channel field, and the first information (RU Index) field and the TWT Channel field share one byte length.

[0148] 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.

[0149] The content of the first wireless frame is exemplarily described below with reference to specific examples.

[0150] The first radio frame includes a channel usage Channel Usage element, the channel usage Channel Usage element includes a usage mode Usage Mode field, and when the identification value of the usage mode Usage Mode field is the first value, the usage mode Usage Mode field is a first information field, which is used to indicate that the STA has in-device coexistence interference.

[0151] The first wireless frame includes a TWT element field, the TWT element field includes at least one TWT element, each TWT element includes an Individual TWT Parameter Set field and a Control field, the Individual TWT Parameter Set field includes an RU Index field that shares a length of 1 byte with the TWT Channel field, the RU Index field is used to indicate that the first RU with intra-device co-existence interference exists in the TWT SP corresponding to the TWT element of the STA, the Control field includes a second sub-information field, the second sub-information field is used to indicate that the first RU with intra-device co-existence interference exists in the TWT SP corresponding to the TWT element of the STA is in an unavailable state.

[0152] In some embodiments, the first radio frame may be a probe request (Probe Request) frame, an association request (Association Request) frame, or a reassociation request (Reassociation Request) frame.

[0153] S22: The AP sends a second radio frame, where the second radio frame is used to respond to the first radio frame.

[0154] In some embodiments, after receiving the first radio frame sent by the STA, the AP may send a second radio frame to the STA to respond to the first radio frame, that is, to inform the STA that it has learned the relevant information indicated by the first radio frame.

[0155] In some embodiments, the second radio frame may be a probe response frame, an association response frame, or a reassociation response frame.

[0156] In some embodiments, when the first radio frame includes a first information field, and the first information field is located within a Channel Usage element, the second radio frame may or may not include the Channel Usage element. When the second radio frame includes the Channel Usage element, the identification value of the Usage Mode field in the Channel Usage element is the first value.

[0157] Optionally, when the second wireless frame includes channel usage Channel Usage, and the identification value of the usage mode Usage Mode field in the channel usage element Channel Usage is the first value, the second wireless frame may include a second information field, that is, a TWT element field.

[0158] Among them, the setting method of the TWT element field in the second wireless frame is consistent with the setting method of the second information field (TWT element field) in the first wireless frame.

[0159] In some embodiments, after receiving the second wireless frame, the STA may also send an acknowledgment frame to the AP. The acknowledgment frame is used to inform the AP that the STA has confirmed that the AP is aware of the relevant information indicated by the first wireless frame, such as the existence of in-device co-existence interference in the STA and / or the existence of an RU with in-device co-existence interference in the STA.

[0160] S23 , the STA determines the second RU allocated by the AP, and communicates with the AP according to the second RU.

[0161] In some embodiments, after the STA receives the second radio frame, or after sending an acknowledgment frame to the AP, the STA may determine the second RU allocated to it by the AP.

[0162] The second RU is used for communication between the STA and the AP.

[0163] Based on this, the STA can communicate with the AP according to the second RU allocated by the AP.

[0164] In some embodiments, the second RU allocated by the AP within the TWT SP corresponding to each TWT element is different from the first RU indicated by the first sub-information field in the corresponding TWT element.

[0165] That is, the second RU allocated by the AP within each TWT SP is different from the first RU of the STA with in-device co-existence interference within the TWT SP. In other words, after receiving the first wireless frame, the AP can determine that the STA is conducting other wireless communications within the first RU with in-device co-existence interference within each TWT SP, such as determined based on the first sub-information field in each TWT element in the first wireless frame. And / or, after receiving the first wireless frame, the AP can determine that the first RU of the STA with in-device co-existence interference within each TWT SP is in an unavailable state, such as determined based on the second sub-information field in each TWT element.

[0166] In this case, the AP will not allocate the first RU with intra-device co-existence interference within each TWT SP to the STA, that is, the AP will allocate other RUs to the STA except the first RU with intra-device co-existence interference within each TWT SP to avoid interference in the communication between the STA and the AP.

[0167] The communication method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, any one of steps S21 to S23 may be implemented as an independent embodiment, and any combination of steps S21 to S23 may be implemented as an independent embodiment, but is not limited thereto.

[0184] As an example, the format of the Individual TWT Parameter Set field may be as follows:

[0185] The target wake-up time parameter set (Individual TWT Parameter Set) field includes the TWT Channel field, and the first information (RU Index) field and the TWT Channel field share one byte length.

[0186] 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.

[0191] S32: Send a first wireless frame.

[0192] The communication method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, any one of steps S31 and S32 may be implemented as an independent embodiment, and steps S31 and S32 may be implemented as independent embodiments, but are not limited thereto.

[0193] FIG4 is a second flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG4 , the method is executed by a STA and includes:

[0194] S41: Determine a first radio frame, where the first radio frame includes a first information field, and the first information field is used to indicate that in-device coexistence interference exists for a STA.

[0196] S42, sending a first wireless frame.

[0197] In some embodiments, the implementation of step S42 can refer to the implementation shown in step S32 in Figure 3, and will not be repeated here.

[0198] S43: Receive a second wireless frame sent by the AP, where the second wireless frame is used to respond to the first wireless frame.

[0199] In some embodiments, after receiving a first radio frame sent by a STA, the AP may send a second radio frame to the STA in response to the first radio frame, i.e., to inform the STA that it has learned the relevant information indicated by the first radio frame. In this manner, after sending the first radio frame, the STA may receive the second radio frame sent by the AP.

[0200] In some embodiments, the second radio frame may be a probe response frame, an association response frame, or a reassociation response frame.

[0201] In some embodiments, when the first radio frame includes a first information field, and the first information field is located within a Channel Usage element, the second radio frame may or may not include the Channel Usage element.

[0203] Among them, the setting method of the TWT element field in the second wireless frame is consistent with the setting method of the second information field (TWT element field) in the first wireless frame.

[0204] In some embodiments, after receiving the second wireless frame, the STA may also send an acknowledgment frame to the AP. The acknowledgment frame is used to inform the AP that the STA has confirmed that the AP is aware of the relevant information indicated by the first wireless frame, such as the existence of in-device co-existence interference in the STA and / or the existence of an RU with in-device co-existence interference in the STA.

[0205] S44: Determine a second RU allocated by the AP, and communicate with the AP according to the second RU.

[0206] In some embodiments, after the STA receives the second radio frame, or after sending an acknowledgment frame to the AP, the STA may determine the second RU allocated to it by the AP.

[0207] The second RU is used for communication between the STA and the AP.

[0208] Based on this, the STA can communicate with the AP according to the second RU allocated by the AP.

[0209] In some embodiments, the second RU allocated by the AP within the TWT SP corresponding to each TWT element is different from the first RU indicated by the first sub-information field in the corresponding TWT element.

[0210] That is, the second RU allocated to it by the AP obtained by the STA is the other RU other than the first RU that coexists with interference in the device within each TWT SP of the STA, so that when the STA communicates with the AP based on the second RU, the communication between the STA and the AP can be avoided from being interfered with.

For example, any one of steps S41 to S44 may be implemented as an independent embodiment, and steps S41 to S44 may be implemented as an independent embodiment, but are not limited thereto.

[0213] S51: Receive a first radio frame, where the first radio frame includes a first information field, and the first information field is used to indicate that in-device coexistence interference exists for a STA.

[0214] In some embodiments, the first radio frame may include a first information field, where the first information field is used to indicate that in-device coexistence interference exists for the STA.

[0215] 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 coexistence interference.

[0223] As an example, each TWT element includes a first sub-information field, where the first sub-information field is used to indicate to the STA that there is a first RU of in-device coexistence interference within the TWT SP corresponding to the TWT element.

[0224] 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 with in-device coexistence interference is in an unavailable state.

[0230] 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.

[0231] The content of the first wireless frame is exemplarily described below with reference to specific examples.

[0232] The first radio frame includes a channel usage Channel Usage element, the channel usage Channel Usage element includes a usage mode Usage Mode field, and when the identification value of the usage mode Usage Mode field is the first value, the usage mode Usage Mode field is a first information field, which is used to indicate that the STA has in-device coexistence interference.

[0235] FIG6 is a fourth flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG6 , the method is executed by an AP and includes:

[0236] S61: Receive a first radio frame, where the first radio frame includes a first information field, and the first information field is used to indicate that in-device coexistence interference exists for a STA.

[0237] In some embodiments, the implementation of step S61 can refer to the implementation shown in step S51 in Figure 5, and will not be repeated here.

[0238] S62: Send a second radio frame, where the second radio frame is used to respond to the first radio frame.

[0239] In some embodiments, after receiving the first radio frame sent by the STA, the AP may send a second radio frame to the STA to respond to the first radio frame, that is, to inform the STA that it has learned the relevant information indicated by the first radio frame.

[0240] In some embodiments, the second radio frame may be a probe response frame, an association response frame, or a reassociation response frame.

[0241] In some embodiments, when the first radio frame includes a first information field, and the first information field is located within a Channel Usage element, the second radio frame may or may not include the Channel Usage element. When the second radio frame includes the Channel Usage element, the identification value of the Usage Mode field in the Channel Usage element is the first value.

[0242] Optionally, when the second wireless frame includes channel usage Channel Usage, and the identification value of the usage mode Usage Mode field in the channel usage element Channel Usage is the first value, the second wireless frame may include a second information field, that is, a TWT element field.

[0243] Among them, the setting method of the TWT element field in the second wireless frame is consistent with the setting method of the second information field (TWT element field) in the first wireless frame.

[0244] In some embodiments, after the AP sends the second wireless frame to the STA, it can also receive a confirmation frame sent by the STA. The confirmation frame is used to inform the AP that the STA has confirmed that the AP is aware of the relevant information indicated by the first wireless frame, such as the existence of in-device co-existence interference in the STA and / or the existence of an RU with in-device co-existence interference in the STA.

[0245] S63: Allocate a second RU to the STA, and communicate with the STA according to the second RU.

[0246] In some embodiments, after the AP sends the second radio frame, or after receiving the confirmation frame sent by the STA, the AP may allocate a second RU to the AP and communicate with the STA according to the second RU.

[0247] The second RU is used for communication between the STA and the AP.

[0248] In some embodiments, the second RU allocated by the AP within the TWT SP corresponding to each TWT element is different from the first RU indicated by the first sub-information field in the corresponding TWT element.

[0249] That is, the second RU allocated by the AP within each TWT SP is different from the first RU of the STA with in-device co-existence interference within the TWT SP. In other words, after receiving the first wireless frame, the AP can determine that the STA is conducting other wireless communications within the first RU with in-device co-existence interference within each TWT SP, such as determined based on the first sub-information field in each TWT element in the first wireless frame. And / or, after receiving the first wireless frame, the AP can determine that the first RU of the STA with in-device co-existence interference within each TWT SP is in an unavailable state, such as determined based on the second sub-information field in each TWT element.

[0250] In this case, the AP will not allocate the first RU with intra-device co-existence interference within each TWT SP to the STA, that is, the AP will allocate other RUs to the STA except the first RU with intra-device co-existence interference within each TWT SP to avoid interference in the communication between the STA and the AP.

[0251] The communication method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, any one of steps S61 to S63 may be implemented as an independent embodiment, and any combination of steps S61 to S63 may be implemented as an independent embodiment, but the present disclosure is not limited thereto.
