[0137] 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 communication 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, communication between the various communication systems can interfere with each other, impacting their transmission and reception. Both Wi-Fi and BT operate in the 2.4 GHz frequency band, and in most communication devices, Wi-Fi and BT modules share antennas. Therefore, mutual interference and conflicts between Wi-Fi and BT occur, both within a single node and across multiple nodes. Furthermore, with the increasing bandwidth of wireless communication systems and the continuous expansion of bandwidth, the problem of interference between multiple wireless communications within a device is becoming increasingly serious, reducing the reliability of data transmission between devices.

[0138] When Non-AP MLD enables an Enhanced Multi-Link Single Radio (EMLSR) link, STAs operating on the EMLSR link and attached to the Non-AP MLD device enter a listening mode and receive initial control frames sent by the AP MLD. If a STA operating on the EMLSR link and attached to the Non-AP MLD device engages in intra-device coexistence activities, such as peer-to-peer communication or BT communication, EMLSR operation mode may fail to be enabled or the STA may be unable to receive initial control frames sent by the AP MLD, resulting in communication interruption or packet loss.

[0139] 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.

[0147] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. The communication method shown in FIG2 includes:

[0148] S21. The Non-AP MLD sends a first radio frame, where the first radio frame is used to indicate whether there is at least one second STA with in-device coexistence activity among the first STAs.

[0149] In some embodiments, the first STA is attached to the Non-AP MLD and operates on the EMLSR link. That is, the first STA is an attached STA of the Non-AP MLD and operates on the EMLSR link.

[0150] In some embodiments, the second STA is a STA that is affiliated with the Non-AP MLD and operates on the EMLSR link and has in-device coexistence activity.

[0151] In some embodiments, the first radio frame may be an enhanced multi-link operating mode notification (EML Operating Mode Notification) frame.

[0152] In some embodiments, the first radio frame includes a first information field, the first information field indicates that there is at least one second STA in the first STA through a first value, and indicates that there is no second STA in the first STA through a second value.

[0153] The first value and the second value are different values. For example, the first value may be 1 and the second value may be 0, which is not limited here.

[0154] As an example, when the identification value of the first information field is 1, the first wireless frame is used to indicate that there is at least one second STA in the first STA; when the identification value of the first information field is 0, the first wireless frame is used to indicate that there is no second STA in the first STA.

[0155] In some embodiments, the first information field may be an In-Device Coexistence Activities field.

[0156] In some embodiments, the first radio frame includes an enhanced multi-link control (EML Control) field, and the EML Control field includes a first information field.

[0157] As an example, the first wireless frame is an EML Operating Mode Notification frame, the EML Operating Mode Notification frame includes an EML Control field, the EML Control field includes an In-Device Coexistence Activities field, when the identification value of the In-Device Coexistence Activities field is a first value, the first wireless frame is used to indicate that there is at least one second STA in the first STA, and when the identification value of the In-Device Coexistence Activities field is a second value, the first wireless frame is used to indicate that there is no second STA in the first STA.

[0158] In some embodiments, when there is at least one second STA in the first STA, the first radio frame further includes at least one second information field, and each second information field corresponds to one second STA.

[0159] Optionally, the second information field may be a per-Link-IDC Activities field.

[0160] Each second information field includes at least one of the following:

[0161] The first sub-information field is used to indicate the link identifier of the EMLSR link on which the corresponding second STA works;

[0162] At least one second sub-information field, each second sub-information field is used to indicate activity information of an in-device coexistence activity existing in a corresponding second STA.

[0163] As an example, when the first wireless frame is used to indicate that there is at least one second STA in the first STA, or when the first information field in the first wireless frame indicates that there is at least one second STA in the first STA through a first value, the first wireless frame may also include at least one second information field.

[0164] Specifically, when each second information field includes the first sub-information field, the first sub-information field indicates a link identifier (Link ID), and the communication link corresponding to the link identifier is an EMLSR link on which a second STA works.

[0165] The link identifiers indicated by each first sub-information field in the second information field are different.

[0166] Optionally, the first sub-information field in each second information field may be a link identification field (Link ID).

[0167] Specifically, when each second information field includes at least one second sub-information field, each second sub-information field is used to indicate activity information of an in-device coexistence activity existing in the corresponding second STA.

[0168] Each second sub-information field in the second information field is used to indicate activity information of the coexistence activity in different devices corresponding to the corresponding second STA.

[0169] Optionally, each second sub-information field in the second information field may be a per-IDC Activity field.

[0170] As an example, the second STAs in the first STA are STA1 and STA2, and the first radio frame includes a second information field corresponding to STA1 and a second information field corresponding to STA2.

[0171] The second information field corresponding to STA1 includes a first sub-information field and at least one second sub-information field. The first sub-information field in the second information field corresponding to STA1 is used to indicate the link identifier of the EMLSR link on which STA1 operates, and each second sub-information field in the second information field corresponding to STA1 is used to indicate activity information of an in-device coexistence activity occurring in STA1. The first sub-information field in the second information field corresponding to STA2 is used to indicate the link identifier of the EMLSR link on which STA2 operates, and each second sub-information field in the second information field corresponding to STA2 is used to indicate activity information of an in-device coexistence activity occurring in STA2.

[0172] The in-device coexistence activity of each second STA may be a communication activity of the second STA in a communication system.

[0173] In some embodiments, when there is at least one second STA in the first STA, and the second information field in the first radio frame includes at least one second sub-information field, each second sub-information field further includes at least one of the following:

[0174] A first identification field, where the first identification field is used to indicate an index of a corresponding intra-device coexistence activity;

[0175] A second identification field, the second identification field is used to indicate the start time of the corresponding intra-device coexistence activity;

[0176] The third identification field is used to indicate the duration of the corresponding intra-device coexistence activity.

[0177] The first identification field is used to indicate the index of the intra-device coexistence activity corresponding to the second sub-information field, that is, to identify the intra-device coexistence activity corresponding to the second sub-information field.

[0178] The first identification field may be an intra-device coexistence activity index (IDC Activity Index) field.

[0179] The second identification field is used to indicate the activity start time of the coexistence activity in the device corresponding to the second sub-information field.

[0180] The second identification field may be an IDC Activity Start Time field.

[0181] The third identification field is used to indicate the activity duration of the coexistence activity within the device corresponding to the second sub-information field.

[0182] The third identification field may be an IDC Activity Duration field.

[0183] In some embodiments, when there is at least one second STA in the first STA, the first wireless frame includes a first element, such as an enhanced multi-link single radio device coexistence activity element (EMLSR IDC Activities element), and the enhanced multi-link single radio device coexistence activity element includes at least one second information field, and each second information field corresponds to a second STA.

[0184] As an example, the first wireless frame includes an EML Control (Enhanced Multi-Link Control) field, the EML Control field includes an In-Device Coexistence Activities field (i.e., a first information field), and when the identification value of the In-Device Coexistence Activities field is 1, the first wireless frame is used to indicate that there is at least one second STA in the first STA, and when the identification value of the In-Device Coexistence Activities field is a second value, the first wireless frame is used to indicate that there is no second STA in the first STA.

[0185] When the identifier value of the In-Device Coexistence Activities field is a first value, the first radio frame includes an enhanced multi-link single radio intra-device coexistence activities element (EMLSR IDC Activities element). As shown in the frame format of the first radio frame in the following table, the first element is an optional element. When the identifier value of the In-Device Coexistence Activities field is a first value, the first radio frame includes the first element, for example, including an enhanced multi-link single radio intra-device coexistence activities element (EMLSR IDC Activities element).

[0186] 3 , the enhanced multi-link single radio intra-device coexistence activities element (EMLSR IDC Activities element) includes at least one per-Link-IDC Activities field (ie, the second information field).

[0187] Each perLink-IDC Activities field includes a link identifier (Link ID) field (ie, a first sub-information field) and at least one single device coexistence activity (per-IDC Activity) field (ie, a second sub-information field).

[0188] The Link ID field is used to indicate a link identifier (Link ID), and the communication link corresponding to the link identifier is an EMLSR link on which a second STA works.

[0189] Each per-IDC Activity field is used to indicate activity information of an in-device coexistence activity of a second STA operating on the EMLSR link identified by the Link ID field.

[0190] Among them, each per-IDC Activity field includes an intra-device coexistence activity index (IDC Activity Index) field (i.e., a first identification field), an intra-device coexistence activity start time (IDC Activity Start Time) field (i.e., a second identification field), and an intra-device coexistence activity duration (IDC Activity Duration) field (i.e., a third identification field).

[0191] The IDC Activity Index field is used to indicate the index of the corresponding intra-device coexistence activity, the IDC Activity Start Time field is used to indicate the start time of the corresponding intra-device coexistence activity, and the IDC Activity Duration field is used to indicate the duration of the corresponding intra-device coexistence activity.

[0192] S22 , the AP MLD determines whether there is at least one second STA present in the first STA.

[0193] In some embodiments, after receiving the first radio frame, the AP MLD may directly determine whether at least one second STA exists within the first STA based on the first radio frame. If at least one second STA exists within the first STA, step S24 is executed; if no second STA exists within the first STA, step S26 is executed.

[0194] S23, the AP MLD sends a second radio frame to the third STA outside each first time interval of the third STA, and / or sends a second radio frame to the fourth STA; the second radio frame is used to respond to the first radio frame.

[0195] In some embodiments, after receiving the second radio frame transmitted by the non-AP MLD, the AP MLD is ready to communicate with the non-AP MLD in the EMLSR state. If at least one second STA exists among the first STAs, the AP MLD does not transmit the second radio frame to any second STA in the in-device coexistence activity. Simultaneously, the AP MLD transmits the second radio frame to the third STA outside each first time interval of the third STA, and / or transmits the second radio frame to the fourth STA in response to the first radio frame with the second radio frame.

[0196] The third STA is any second STA, and each first time interval of the third STA is the activity time of an in-device coexistence activity of the third STA.

[0197] Among them, a first time interval of the third STA is determined by the start time of the in-device coexistence activity indicated by the second identification field included in a second sub-information field in the second information field corresponding to the third STA in the first wireless frame, and the duration of the in-device coexistence activity indicated by the third identification field.

[0198] As an example, the first wireless frame includes a second information field corresponding to the third STA, and the second information field corresponding to the third STA includes at least one second sub-information field. The second identification field and the third identification field in each second sub-information field can be used to determine the activity time of an intra-device coexistence activity in which the third STA exists, that is, to determine a first time interval of the third STA.

[0199] As an example, the second STAs in the first STA are STA3 and STA4. When the AP MLD sends the second wireless frame to STA3, it is necessary to send the second wireless frame to STA3 outside each first time interval of STA3. When the AP MLD sends the second wireless frame to STA4, it is necessary to send the second wireless frame to STA4 outside each first time interval of STA4.

[0200] The fourth STA is any STA in the first STA except the second STA, that is, the fourth STA is any STA in the STAs attached to the Non-AP MLD and working on the EMLSR link, and there is no intra-device coexistence activity.

[0201] As an example, the first STAs are STA5, STA6, and STA7, wherein STA5 and STA6 have in-device coexistence activities, and STA7 does not have in-device coexistence activities, and the AP MLD can send the second radio frame to STA7 at any time.

[0202] In some embodiments, the second radio frame sent by the AP MLD may be an enhanced multi-link operating mode notification (EML Operating Mode Notification) frame.

[0203] In some embodiments, the second radio frame sent by the AP MLD may not include each second information field.

[0204] The first information field in the second radio frame is a reserved bit. When the second radio frame sent by the AP MLD includes an Enhanced Multi-Link Control (EML Control) field, the In-Device Coexistence Activities field in the EML Control field is a reserved bit.

[0205] It should be noted that when the AP MLD sends the second radio frame to the third STA, the AP MLD sends the second radio frame to the third STA via the subordinate AP that operates on the same communication link and has established an association with the third STA. When the AP MLD sends the second radio frame to the fourth STA, the AP MLD sends the second radio frame to the fourth STA via the subordinate AP that operates on the same communication link and has established an association with the fourth STA.

[0206] S24, the AP MLD sends an initial control frame to the third STA outside each first time interval of the third STA, and / or sends an initial control frame to the fourth STA; the initial control frame is used to instruct data transmission with the Non-AP MLD.

[0207] In some embodiments, when there is at least one second STA among the first STAs, when the AP MLD needs to perform data transmission with the Non-AP MLD, the AP MLD may send an initial control frame to the Non-AP MLD.

[0208] The initial control frame is used to instruct data transmission with the Non-AP MLD.

[0209] Specifically, in the case that there is at least one second STA among the first STAs, the manner in which the AP MLD sends the initial control frame is the same as the manner in which the AP MLD sends the second radio frame.

[0210] That is, in the case where there is at least one second STA among the first STAs, the AP MLD does not send an initial control frame to any second STA in the in-device coexistence activity.

[0211] Optionally, when there is at least one second STA among the first STAs, the AP MLD sends an initial control frame to the third STA outside each first time interval of the third STA.

[0212] The third STA is any second STA, and each first time interval of the third STA is the activity time of an in-device coexistence activity of the third STA.

[0213] Among them, a first time interval of the third STA is determined by the start time of the in-device coexistence activity indicated by the second identification field included in a second sub-information field in the second information field corresponding to the third STA in the first wireless frame, and the duration of the in-device coexistence activity indicated by the third identification field.

[0214] As an example, the first wireless frame includes a second information field corresponding to the third STA, and the second information field corresponding to the third STA includes at least one second sub-information field. The second identification field and the third identification field in each second sub-information field can be used to determine the activity time of an intra-device coexistence activity in which the third STA exists, that is, to determine a first time interval of the third STA.

[0215] As an example, the second STAs in the first STA are STA8 and STA9. When the AP MLD sends an initial control frame to STA8, it is necessary to send the initial control frame to STA8 outside each first time interval of STA8. When the AP MLD sends an initial control frame to STA9, it is necessary to send the initial control frame to STA9 outside each first time interval of STA9.

[0216] Optionally, in a case where there is at least one second STA among the first STAs, the AP MLD may send an initial control frame to the fourth STA.

[0217] The fourth STA is any STA among the first STAs except the second STA, that is, the fourth STA is any STA among the STAs attached to the Non-AP MLD and working on the EMLSR link, without any intra-device coexistence activity.

[0218] As an example, the first STAs are STA10, STA11, and STA12, wherein STA10 and STA11 have in-device coexistence activities, and STA12 does not have in-device coexistence activities. The AP MLD can send an initial control frame to STA12 at any time.

[0219] It should be noted that when the AP MLD sends an initial control frame to the third STA, the AP MLD sends the initial control frame to the third STA through the subordinate AP that operates on the same communication link and has established an association with the third STA. When the AP MLD sends an initial control frame to the fourth STA, the AP MLD sends the initial control frame to the fourth STA through the subordinate AP that operates on the same communication link and has established an association with the fourth STA.

[0220] In some embodiments, the initial control frame may be a Multi-User Request to Send (MU-RTS) trigger frame or a Buffer Status Report Poll (BSRP) trigger frame.

[0221] S25 , the AP MLD sends a second radio frame to any first STA; the second radio frame is used to respond to the first radio frame.

[0222] In some embodiments, when the AP MLD determines that the second STA does not exist in the first STA, it also needs to send a second radio frame to the Non-AP MLD to respond to the first radio frame.

[0223] Specifically, when there is no second STA among the first STAs, the AP MLD may send the second radio frame to any one of the first STAs.

[0224] It should be noted that, when the AP MLD sends the second radio frame to any first STA, the AP MLD sends the second radio frame to the first STA through the subordinate AP that works on the same communication link as the first STA and has established an association with the first STA.

[0225] S26, the AP MLD sends an initial control frame to any first STA; the initial control frame is used to respond to the first radio frame.

[0226] In some embodiments, when the AP MLD determines that there is no second STA among the first STAs, the AP MLD may send an initial control frame to any one of the first STAs when data transmission with the Non-AP MLD is required.

[0227] It should be noted that, when the AP MLD sends the initial control frame to any first STA, the AP MLD sends the initial control frame to the first STA through the subordinate AP that works on the same communication link as the first STA and has established an association with the first STA.

[0228] In some embodiments, the initial control frame may be a MU-RTS Trigger frame or a BSRP Trigger frame.

[0229] In some embodiments, after the Non-AP MLD receives the initial control frame sent by the AP MLD, data transmission can be performed between the Non-AP MLD and the AP MLD.

[0230] 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 S27 may be implemented as an independent embodiment, any combination of steps S21 to S24 may be implemented as an independent embodiment, and any combination of steps S21 to S22 and steps S25 to S26 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0243] Optionally, the second information field may be a per-Link-IDC Activities field.

[0244] Each second information field includes at least one of the following:

[0246] At least one second sub-information field, each second sub-information field is used to indicate activity information of an in-device coexistence activity existing in a corresponding second STA.

[0247] As an example, when the first wireless frame is used to indicate that there is at least one second STA in the first STA, or when the first information field in the first wireless frame indicates that there is at least one second STA in the first STA through a first value, the first wireless frame may also include at least one second information field.

[0248] Specifically, when each second information field includes the first sub-information field, the first sub-information field indicates a link identifier (Link ID), and the communication link corresponding to the link identifier is an EMLSR link on which a second STA works.

[0249] The link identifiers indicated by each first sub-information field in the second information field are different.

[0250] Optionally, the first sub-information field in each second information field may be a link identification field (Link ID).

[0251] Specifically, when each second information field includes at least one second sub-information field, each second sub-information field is used to indicate activity information of an in-device coexistence activity existing in the corresponding second STA.

[0252] Each second sub-information field in the second information field is used to indicate activity information of the coexistence activity in different devices corresponding to the corresponding second STA.

[0253] Optionally, each second sub-information field in the second information field may be a per-IDC Activity field.

[0254] The in-device coexistence activity of each second STA may be a communication activity of the second STA in a communication system.

[0255] In some embodiments, when there is at least one second STA in the first STA, and the second information field in the first radio frame includes at least one second sub-information field, each second sub-information field further includes at least one of the following:

[0257] A second identification field, the second identification field is used to indicate the start time of the corresponding intra-device coexistence activity;

[0258] The third identification field is used to indicate the duration of the corresponding intra-device coexistence activity.

[0259] The first identification field is used to indicate the index of the intra-device coexistence activity corresponding to the second sub-information field, that is, to identify the intra-device coexistence activity corresponding to the second sub-information field.

[0260] The first identification field may be an intra-device coexistence activity index (IDC Activity Index) field.

[0279] In some embodiments, when there is at least one second STA in the first STA, the Non-AP MLD does not receive the second radio frame through any second STA in which in-device coexistence is active.

[0280] Optionally, when there is at least one second STA among the first STAs, the Non-AP MLD receives the second radio frame through the third STA outside each first time interval of the third STA.

[0281] The third STA is any second STA, and each first time interval of the third STA is the activity time of an in-device coexistence activity of the third STA.

[0282] Among them, a first time interval of the third STA is determined by the start time of the in-device coexistence activity indicated by the second identification field included in a second sub-information field in the second information field corresponding to the third STA in the first wireless frame, and the duration of the in-device coexistence activity indicated by the third identification field.

[0283] As an example, the first wireless frame includes a second information field corresponding to the third STA, and the second information field corresponding to the third STA includes at least one second sub-information field. The second identification field and the third identification field in each second sub-information field can be used to determine the activity time of an intra-device coexistence activity in which the third STA exists, that is, to determine a first time interval of the third STA.

[0284] Optionally, in a case where there is at least one second STA among the first STAs, the Non-AP MLD may receive the second radio frame through a fourth STA.

[0285] The fourth STA is any STA in the first STA except the second STA, that is, the fourth STA is any STA in the STAs attached to the Non-AP MLD and working on the EMLSR link, and there is no intra-device coexistence activity.

[0286] In the case that there is no second STA among the first STAs, the Non-AP MLD may receive the second radio frame through any one of the first STAs.

[0287] It should be noted that the second wireless frame received by the Non-AP MLD through the third STA, the fourth STA or any first STA (for the convenience of description, the third STA, the fourth STA or any first STA that needs to receive the second wireless frame is referred to as the target STA) is sent by the AP MLD through the affiliated AP that works on the same communication link and establishes an association with the target STA.

[0288] S54: Receive an initial control frame, where the initial control frame is used to instruct data transmission with the Non-AP MLD.

[0289] In some embodiments, the initial control frame is sent when the AP MLD needs to perform data transmission with the Non-AP MLD.

[0290] The initial control frame is used to instruct data transmission with the Non-AP MLD.

[0291] In some embodiments, the initial control frame may be a MU-RTS Trigger frame or a BSRP Trigger frame.

[0292] In some embodiments, in the case where there is at least one second STA in the first STA, the Non-AP MLD does not receive the initial control frame through any second STA in which in-device coexistence is active.

[0293] Optionally, in a case where there is at least one second STA among the first STAs, the Non-AP MLD receives an initial control frame through the third STA outside each first time interval of the third STA.

[0294] The third STA is any second STA, and each first time interval of the third STA is the activity time of an in-device coexistence activity of the third STA.

[0295] Among them, a first time interval of the third STA is determined by the start time of the in-device coexistence activity indicated by the second identification field included in a second sub-information field in the second information field corresponding to the third STA in the first wireless frame, and the duration of the in-device coexistence activity indicated by the third identification field.

[0296] As an example, the first wireless frame includes a second information field corresponding to the third STA, and the second information field corresponding to the third STA includes at least one second sub-information field. The second identification field and the third identification field in each second sub-information field can be used to determine the activity time of an intra-device coexistence activity in which the third STA exists, that is, to determine a first time interval of the third STA.

[0297] Optionally, in a case where there is at least one second STA among the first STAs, the Non-AP MLD may receive the initial control frame through the fourth STA.

[0298] The fourth STA is any STA in the first STA except the second STA, that is, the fourth STA is any STA in the STAs attached to the Non-AP MLD and working on the EMLSR link, and there is no intra-device coexistence activity.

[0299] In the case that there is no second STA among the first STAs, the Non-AP MLD can receive the initial control frame through any first STA.

[0300] It should be noted that the initial control frame received by the Non-AP MLD through the third STA, the fourth STA or any first STA (for the convenience of description, the third STA, the fourth STA or any first STA that needs to receive the initial control frame is referred to as the target STA below) is sent by the AP MLD through the affiliated AP that works on the same communication link and establishes an association with the target STA.

[0301] In some embodiments, after receiving the initial control frame, the Non-AP MLD may perform data transmission with the AP MLD through the EMLSR link.

[0302] 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 S51 to S53 may be implemented as an independent embodiment, and steps S51 to S53 may be implemented as an independent embodiment, but are not limited thereto.

[0303] FIG6 is a third flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG6 , the method is executed by the AP MLD and includes:

[0304] S61: Receive a first radio frame, where the first radio frame is used to indicate whether there is at least one second STA with in-device coexistence activity among the first STAs.

[0305] In some embodiments, the first STA is attached to the Non-AP MLD and operates on the EMLSR link. That is, the first STA is an attached STA of the Non-AP MLD and operates on the EMLSR link.

[0306] In some embodiments, the second STA is a STA that is affiliated with the Non-AP MLD and operates on the EMLSR link and has in-device coexistence activity.

[0307] In some embodiments, the first radio frame may be an enhanced multi-link operating mode notification (EML Operating Mode Notification) frame.

[0308] In some embodiments, the first radio frame includes a first information field, the first information field indicates that there is at least one second STA in the first STA through a first value, and indicates that there is no second STA in the first STA through a second value.

[0309] The first value and the second value are different values. For example, the first value may be 1 and the second value may be 0, which is not limited here.

[0310] As an example, when the identification value of the first information field is 1, the first wireless frame is used to indicate that there is at least one second STA in the first STA; when the identification value of the first information field is 0, the first wireless frame is used to indicate that there is no second STA in the first STA.

[0311] In some embodiments, the first information field may be an In-Device Coexistence Activities field.

[0312] In some embodiments, the first radio frame includes an enhanced multi-link control (EML Control) field, and the EML Control field includes a first information field.

[0313] As an example, the first wireless frame is an EML Operating Mode Notification frame, the EML Operating Mode Notification frame includes an EML Control field, the EML Control field includes an In-Device Coexistence Activities field, when the identification value of the In-Device Coexistence Activities field is a first value, the first wireless frame is used to indicate that there is at least one second STA in the first STA, and when the identification value of the In-Device Coexistence Activities field is a second value, the first wireless frame is used to indicate that there is no second STA in the first STA.

[0314] In some embodiments, when there is at least one second STA in the first STA, the first radio frame further includes at least one second information field, and each second information field corresponds to one second STA.

[0315] Optionally, the second information field may be a per-Link-IDC Activities field.

[0316] Each second information field includes at least one of the following:

[0317] The first sub-information field is used to indicate the link identifier of the EMLSR link on which the corresponding second STA works;

[0318] At least one second sub-information field, each second sub-information field is used to indicate activity information of an in-device coexistence activity existing in a corresponding second STA.

[0319] As an example, when the first wireless frame is used to indicate that there is at least one second STA in the first STA, or when the first information field in the first wireless frame indicates that there is at least one second STA in the first STA through a first value, the first wireless frame may also include at least one second information field.

[0320] Specifically, when each second information field includes the first sub-information field, the first sub-information field indicates a link identifier (Link ID), and the communication link corresponding to the link identifier is an EMLSR link on which a second STA works.

[0321] The link identifiers indicated by each first sub-information field in the second information field are different.

[0322] Optionally, the first sub-information field in each second information field may be a link identification field (Link ID).

[0323] Specifically, when each second information field includes at least one second sub-information field, each second sub-information field is used to indicate activity information of an in-device coexistence activity existing in the corresponding second STA.

[0324] Each second sub-information field in the second information field is used to indicate activity information of the coexistence activity in different devices corresponding to the corresponding second STA.

[0325] Optionally, each second sub-information field in the second information field may be a per-IDC Activity field.

[0326] As an example, the second STAs in the first STA are STA1 and STA2, and the first radio frame includes a second information field corresponding to STA1 and a second information field corresponding to STA2.

[0327] The second information field corresponding to STA1 includes a first sub-information field and at least one second sub-information field. The first sub-information field in the second information field corresponding to STA1 is used to indicate the link identifier of the EMLSR link on which STA1 operates, and each second sub-information field in the second information field corresponding to STA1 is used to indicate activity information of an in-device coexistence activity occurring in STA1. The first sub-information field in the second information field corresponding to STA2 is used to indicate the link identifier of the EMLSR link on which STA2 operates, and each second sub-information field in the second information field corresponding to STA2 is used to indicate activity information of an in-device coexistence activity occurring in STA2.

[0328] The in-device coexistence activity of each second STA may be a communication activity of the second STA in a communication system.

[0329] In some embodiments, when there is at least one second STA in the first STA, and the second information field in the first radio frame includes at least one second sub-information field, each second sub-information field further includes at least one of the following:

[0330] A first identification field, where the first identification field is used to indicate an index of a corresponding intra-device coexistence activity;

[0331] A second identification field, the second identification field is used to indicate the start time of the corresponding intra-device coexistence activity;

[0332] The third identification field is used to indicate the duration of the corresponding intra-device coexistence activity.

[0333] The first identification field is used to indicate the index of the intra-device coexistence activity corresponding to the second sub-information field, that is, to identify the intra-device coexistence activity corresponding to the second sub-information field.

[0334] The first identification field may be an intra-device coexistence activity index (IDC Activity Index) field.

[0335] The second identification field is used to indicate the activity start time of the coexistence activity in the device corresponding to the second sub-information field.

[0336] The second identification field may be an IDC Activity Start Time field.

[0337] The third identification field is used to indicate the activity duration of the coexistence activity within the device corresponding to the second sub-information field.

[0338] The third identification field may be an IDC Activity Duration field.

[0339] In some embodiments, when there is at least one second STA in the first STA, the first wireless frame includes a first element, such as an enhanced multi-link single radio device coexistence activity element (EMLSR IDC Activities element), and the enhanced multi-link single radio device coexistence activity element includes at least one second information field, and each second information field corresponds to a second STA.

[0340] As an example, the first wireless frame includes an EML Control (Enhanced Multi-Link Control) field, the EML Control field includes an In-Device Coexistence Activities field (i.e., a first information field), and when the identification value of the In-Device Coexistence Activities field is 1, the first wireless frame is used to indicate that there is at least one second STA in the first STA, and when the identification value of the In-Device Coexistence Activities field is a second value, the first wireless frame is used to indicate that there is no second STA in the first STA.

[0341] FIG7 is a fourth flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG7 , the method is executed by the AP MLD, and the method includes:

[0342] S71 : Receive a first radio frame, where the first radio frame is used to indicate whether there is at least one second STA with in-device coexistence activity among the first STAs.

[0343] In some embodiments, the implementation of step S71 can refer to the implementation shown in step S61 in Figure 6, and will not be repeated here.

[0344] S72: Send a second radio frame, where the second radio frame is used to respond to the first radio frame.

[0345] In some embodiments, after receiving the second radio frame sent by the Non-AP MLD, the AP MLD may send the second radio frame to the Non-AP MLD in response to the first radio frame if the AP MLD is ready to communicate with the Non-AP MLD in the EMLSR state.

[0346] In some embodiments, the second radio frame sent by the AP MLD may be an enhanced multi-link operating mode notification (EML Operating Mode Notification) frame.

[0347] In some embodiments, the second radio frame sent by the AP MLD may not include each second information field.

[0348] The first information field in the second radio frame is a reserved bit. When the second radio frame sent by the AP MLD includes an Enhanced Multi-Link Control (EML Control) field, the In-Device Coexistence Activities field in the EML Control field is a reserved bit.

[0349] In some embodiments, in a case where there is at least one second STA in the first STA, the AP MLD does not transmit the second radio frame to any second STA in the in-device coexistence activity.

[0350] Optionally, when there is at least one second STA among the first STAs, the AP MLD sends a second radio frame to the third STA outside each first time interval of the third STA.

[0351] The third STA is any second STA, and each first time interval of the third STA is the activity time of an in-device coexistence activity of the third STA.

[0352] Among them, a first time interval of the third STA is determined by the start time of the in-device coexistence activity indicated by the second identification field included in a second sub-information field in the second information field corresponding to the third STA in the first wireless frame, and the duration of the in-device coexistence activity indicated by the third identification field.

[0353] As an example, the first wireless frame includes a second information field corresponding to the third STA, and the second information field corresponding to the third STA includes at least one second sub-information field. The second identification field and the third identification field in each second sub-information field can be used to determine the activity time of an intra-device coexistence activity in which the third STA exists, that is, to determine a first time interval of the third STA.

[0354] As an example, the second STAs in the first STA are STA3 and STA4. When the AP MLD sends the second wireless frame to STA3, it is necessary to send the second wireless frame to STA3 outside each first time interval of STA3. When the AP MLD sends the second wireless frame to STA4, it is necessary to send the second wireless frame to STA4 outside each first time interval of STA4.

[0355] Optionally, in a case where there is at least one second STA among the first STAs, the AP MLD may send a second radio frame to the fourth STA.

[0356] The fourth STA is any STA in the first STA except the second STA, that is, the fourth STA is any STA in the STAs attached to the Non-AP MLD and working on the EMLSR link, and there is no intra-device coexistence activity.

[0357] As an example, the first STAs are STA5, STA6, and STA7, wherein STA5 and STA6 have in-device coexistence activities, and STA7 does not have in-device coexistence activities, and the AP MLD can send the second radio frame to STA7 at any time.

[0358] In the case that there is no second STA among the first STAs, the AP MLD may send the second radio frame to any one of the first STAs.

[0359] It should be noted that when the AP MLD sends the second radio frame to the third STA, the fourth STA or any first STA (for the convenience of description, the third STA, the fourth STA or any first STA that needs to receive the second radio frame is referred to as the target STA), the AP MLD sends the second radio frame to the target STA through an affiliated AP that works on the same communication link and establishes an association with the target STA.

[0360] S73: Send an initial control frame, where the initial control frame is used to instruct data transmission with the Non-AP MLD.

[0361] In some embodiments, when the AP MLD needs to perform data transmission with the Non-AP MLD, the AP MLD may send an initial control frame to the Non-AP MLD.

[0362] The initial control frame is used to instruct data transmission with the Non-AP MLD.

[0363] Specifically, the manner in which the AP MLD sends the initial control frame is the same as the manner in which the AP MLD sends the second radio frame.

[0364] That is, in a case where there is at least one second STA among the first STAs, the AP MLD does not send an initial control frame to any second STA in the in-device coexistence activity.

[0365] Optionally, when there is at least one second STA among the first STAs, the AP MLD sends an initial control frame to the third STA outside each first time interval of the third STA.

[0366] The third STA is any second STA, and each first time interval of the third STA is the activity time of an in-device coexistence activity of the third STA.

[0367] Among them, a first time interval of the third STA is determined by the start time of the in-device coexistence activity indicated by the second identification field included in a second sub-information field in the second information field corresponding to the third STA in the first wireless frame, and the duration of the in-device coexistence activity indicated by the third identification field.

[0368] As an example, the first wireless frame includes a second information field corresponding to the third STA, and the second information field corresponding to the third STA includes at least one second sub-information field. The second identification field and the third identification field in each second sub-information field can be used to determine the activity time of an intra-device coexistence activity in which the third STA exists, that is, to determine a first time interval of the third STA.

[0369] As an example, the second STAs in the first STA are STA8 and STA9. When the AP MLD sends an initial control frame to STA8, it is necessary to send the initial control frame to STA8 outside each first time interval of STA8. When the AP MLD sends an initial control frame to STA9, it is necessary to send the initial control frame to STA9 outside each first time interval of STA9.

[0370] Optionally, in a case where there is at least one second STA among the first STAs, the AP MLD may send an initial control frame to the fourth STA.

[0371] The fourth STA is any STA in the first STA except the second STA, that is, the fourth STA is any STA in the STAs attached to the Non-AP MLD and working on the EMLSR link, and there is no intra-device coexistence activity.

[0372] As an example, the first STAs are STA10, STA11, and STA12, wherein STA10 and STA11 have in-device coexistence activities, and STA12 does not have in-device coexistence activities. The AP MLD can send an initial control frame to STA12 at any time.

[0373] In the case that there is no second STA among the first STAs, the AP MLD may send an initial control frame to any one of the first STAs.

[0374] In some embodiments, the initial control frame may be a MU-RTS Trigger frame or a BSRP Trigger frame.

[0375] It should be noted that when the AP MLD sends an initial control frame to the third STA, the fourth STA or any first STA (for the convenience of description, the third STA, the fourth STA or any first STA that needs to receive the second wireless frame is referred to as the target STA), the AP MLD sends the initial control frame to the target STA through an affiliated AP that works on the same communication link and establishes an association with the target STA.

[0376] In some embodiments, after the AP MLD sends the initial control frame, data can be transmitted with the Non-AP MLD via the EMLSR link.

[0377] 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 S71 to S73 may be implemented as an independent embodiment, and any combination of steps S71 to S73 may be implemented as an independent embodiment, but the present disclosure is not limited thereto.
