[0125] In actual applications, a device supporting Wi-Fi communication also supports communication modes such as a wireless local area network (WLAN), long term evolution (LTE), Bluetooth (BT), and a global navigation satellite system (GNSS), and different communication modes can communicate at the same time.

[0126] In actual applications, for example, a BT and a Wi-Fi share a radio frequency antenna. Specifically, it is assumed that two or four radio frequency antennas are shared when a terminal device performs BT communication or Wi-Fi communication in a 2.4 GHz frequency band or a 5 GHz frequency band. In some cases, if the amount of data transmitted by using the BT communication mode is small, only one radio frequency antenna is needed to complete the transmission. In a specific example, it is assumed that the maximum number of antennas supported by a device is 4. If Wi-Fi communication is performed by using the maximum number of antennas supported by the device, that is, four radio frequency antennas are used for communication. At this time, if the device needs to transmit emergency service data by using the BT mode, and the amount of data to be transmitted is small, for example, one radio frequency antenna is needed to transmit the data, the Wi-Fi communication process needs to be suspended, and one radio frequency antenna is used to transmit the emergency service data transmitted by using the BT mode, so as to ensure that the emergency service data transmitted by using the BT mode can be successfully transmitted.

[0127] However, in the above scenario, in order to ensure that the emergency service data transmitted by using the BT mode can be successfully transmitted, the power modes (in a power saving (PS) mode or an active state) of the other three radio frequency antennas need to be maintained, or in order to make the continuity of Wi-Fi data transmission more likely, it can be considered to continue to transmit Wi-Fi data in other links.

[0128] To cope with at least one of the above requirements, in the embodiments of the present disclosure, in the case that the STA 101 exists communication service of other communication media in addition to Wi-Fi communication service, i.e., in-device coexistence activity, the STA 101 determines and sends a first wireless frame, and the first identification information carried by the first wireless frame identifies: communication resource information required by the STA 101 to transmit the in-device coexistence activity; in this way, the device receiving the first wireless frame can allocate communication resources preferentially to in-device coexistence activities with higher emergency based on the communication resource information required by the STA 101 to transmit the in-device coexistence activity, and determine other communication resources in addition to the communication resources required by the STA 101 to transmit the in-device coexistence activity from the communication resources held by the STA 101, to perform transmission of Wi-Fi service data based on the other communication resources, thereby maximizing the utilization of the communication resources held by the STA 101, improving the utilization of the communication resources held by the STA 101, meeting the UHR requirement, or determining the transmission mode of the Wi-Fi service data based on the other communication resources to avoid interruption of the Wi-Fi communication service.

[0129] Optionally, in the embodiments of the present disclosure, the communication resource information includes at least one of:

[0130] The number of antennas required by the STA 101 to transmit the in-device coexistence activity, the NSS required by the STA 101 to transmit the in-device coexistence activity, and the BW required by the STA 101 to transmit the in-device coexistence activity.

[0131] Optionally, the communication resource information required by the STA 101 to transmit the in-device coexistence activity (i.e., IDC (In-Device Coexistence) service) can include other information associated with the communication resource in addition to the number of antennas required by the STA 101 to transmit the in-device coexistence activity, the NSS, and the bandwidth, etc., which is not limited in the embodiments of the present disclosure and is within the protection scope of the embodiments of the present disclosure.

[0132] In the embodiments of the present disclosure, in the case that the STA 101 exists communication service of other communication media in addition to Wi-Fi communication service, i.e., in-device coexistence activity, the STA 101 determines and sends a first wireless frame, and the first identification information carried by the first wireless frame identifies one or more of the following communication resource information: the number of antennas required by the STA 101 to transmit the in-device coexistence activity, the NSS required by the STA 101 to transmit the in-device coexistence activity, and the BW required by the STA 101 to transmit the in-device coexistence activity. In this way, based on the one or more of the foregoing communication resource information, the device receiving the first wireless frame can preferentially allocate communication resources to the in-device coexistence activity with higher urgency, and determine other communication resources in the communication resources held by the STA 101 in addition to the communication resources required by the STA 101 to transmit the in-device coexistence activity, to perform transmission of Wi-Fi service data based on the other communication resources, thereby maximizing the utilization of the communication resources held by the STA 101, improving the utilization rate of the communication resources held by the STA 101, meeting the UHR requirement, or determining the transmission mode of the Wi-Fi service data based on the other communication resources to avoid interruption of the Wi-Fi communication service.

[0133] Optionally, in the embodiments of the present disclosure, the first wireless frame further includes second identification information, and the second identification information is used to identify interference information generated by the transmission of the in-device coexistence activity on the transmission process of the Wi-Fi service data.

[0134] Optionally, the interference information generated by the transmission of the in-device coexistence activity on the transmission process of the Wi-Fi service data can include interference tolerance, i.e., if the STA 101 transmits Wi-Fi service data through other channels under the link of the transmission of the in-device coexistence activity, the maximum value of the service interference generated by the in-device coexistence activity can be received through the other channels in the process of the STA 101 transmitting the Wi-Fi service data. The other channels are channels other than the channel for transmitting the in-device coexistence activity under the link.

[0135] In some optional embodiments, the first wireless frame can include the first identification information and does not include the second identification information, the second identification information is used to identify interference information generated by the transmission of the in-device coexistence activity on the transmission process of the Wi-Fi service data, and the first identification information identifies communication resource information required by the STA 101 to transmit the in-device coexistence activity.

[0136] In some optional embodiments, the first wireless frame can include first identification information and second identification information, the second identification information being used to identify interference information generated by transmission of the in-device coexistence activity to Wi-Fi service data, and the first identification information being used to identify communication resource information required by the STA 101 for transmission of the in-device coexistence activity.

[0137] In some optional embodiments, the first wireless frame can not include the first identification information but include the second identification information, the second identification information being used to identify interference information generated by transmission of the in-device coexistence activity to Wi-Fi service data, and the first identification information being used to identify communication resource information required by the STA 101 for transmission of the in-device coexistence activity.

[0138] In some optional embodiments, whether the first wireless frame includes the first identification information can not be limited, but the first wireless frame includes the second identification information, the second identification information being used to identify interference information generated by transmission of the in-device coexistence activity to Wi-Fi service data, and the first identification information being used to identify communication resource information required by the STA 101 for transmission of the in-device coexistence activity.

[0139] In some optional embodiments, whether the first wireless frame includes the second identification information can not be limited, but the first wireless frame includes the first identification information, the second identification information being used to identify interference information generated by transmission of the in-device coexistence activity to Wi-Fi service data, and the first identification information being used to identify communication resource information required by the STA 101 for transmission of the in-device coexistence activity.

[0140] Optionally, in the embodiments of the present disclosure, the first wireless frame further includes third identification information, the third identification information being used to identify time information of the in-device coexistence activity; wherein,

[0141] In a case where the in-device coexistence activity is a periodic in-device coexistence activity, the time information includes a transmission period of the in-device coexistence activity, and a duration of the in-device coexistence activity in one transmission period.

[0142] Or

[0143] In a case where the in-device coexistence activity is a non-periodic in-device coexistence activity, the time information includes a duration of the in-device coexistence activity.

[0144] Optionally, the in-device coexistence activity can be divided into a periodic in-device coexistence activity and a non-periodic in-device coexistence activity based on whether a corresponding communication mode of the periodic in-device coexistence activity is required for transmission of service data.

[0145] For example, in a case where the STA 101 needs to transmit data through BT every 40 milliseconds (ms) and the duration of each BT data transmission is 10 ms, it can be determined that the STA 101 transmits Bluetooth data periodically, and the transmission period is 40 ms, and the duration in one transmission period is 10 ms.

[0146] Optionally, in a case where the in-device coexistence activity is a periodic in-device coexistence activity, the first wireless frame can include a request frame or a notification frame; in a case where the in-device coexistence activity is a non-periodic in-device coexistence activity, the first wireless frame can include an initial control frame.

[0147] Optionally, the periodic in-device coexistence activity can also be referred to as periodic IDC traffic, and the non-periodic in-device coexistence activity can also be referred to as bursty IDC traffic, and the names are not limited in the embodiments of the present disclosure.

[0148] In some optional embodiments, the first wireless frame can include any one or a combination of any multiple of the following: first identification information, second identification information, and third identification information, the second identification information is used to identify interference information generated by the transmission of the in-device coexistence activity to Wi-Fi traffic data, the first identification information is used to identify communication resource information required by the STA 101 for transmitting the in-device coexistence activity, and the third identification information is used to identify time information of the in-device coexistence activity. For example, the first wireless frame can include the first identification information, or the first wireless frame can include the first identification information and the third identification information, or the first wireless frame can include the second identification information and the third identification information but not the first identification information, or the first wireless frame can include the first identification information, the second identification information, and the third identification information.

[0149] Optionally, in a case where the STA 101 supports multi-link communication, the first wireless frame further includes fourth identification information, and the fourth identification information is used to identify link information of a link in which the in-device coexistence activity exists.

[0150] Optionally, the link information of the link in which the in-device coexistence activity exists can include a link identifier (link ID) of the link.

[0151] As an example, in a case where the STA 101 supports multi-link communication, and the AP 102 supports multi-link communication, i.e., the STA 101 is an affiliated STA of a non-AP MLD, and the AP is an affiliated AP of an AP MLD, if there is in-device coexistence activity on link 1 (link1) between the non-AP MLD and the AP MLD, there is Wi-Fi traffic on link 2 (link2), and the link1 and the link2 are NSTR (Nonsimultaneous transmit and receive) to each other, or, the link1 and the link2 are both eMLSR (enhanced multi-link single-radio) links, or, the link1 and the link2 are both eMLMR (enhanced multi-link multi-radio) links, the STA 101 can determine a first wireless frame on the link2, and identify the link on which there is in-device coexistence activity in the first wireless frame, for example, carry an identification of the link1, i.e., identify that there is in-device coexistence activity on the link1.

[0152] Optionally, in the first wireless frame, fifth identification information can also be included, the fifth identification information is used to identify an activity type of the in-device coexistence activity, i.e., a corresponding communication mode of the in-device coexistence activity.

[0153] As an example, the fifth identification information can include two bits, when the fifth identification information is set to 00, it indicates that the fifth identification information identifies that the activity type of the in-device coexistence activity is WLAN; when the fifth identification information is set to 01, it indicates that the fifth identification information identifies that the activity type of the in-device coexistence activity is LTE; when the fifth identification information is set to 10, it indicates that the fifth identification information identifies that the activity type of the in-device coexistence activity is BT; and when the fifth identification information is set to 11, it indicates that the fifth identification information identifies that the activity type of the in-device coexistence activity is GNSS.

[0154] Optionally, the link on which there is in-device coexistence activity of a certain type can be accurately identified through the fourth identification information + the fifth identification information. As an example, assuming that the fourth identification information is link1, and the fifth identification information is 10, it identifies that there is traffic data transmitted through BT on the link1.

[0155] In some optional embodiments, the first wireless frame can include any one or a combination of the following: first identification information, second identification information, third identification information, fourth identification information, and fifth identification information. The second identification information is used to identify interference information generated by the transmission of the device coexistence activity to Wi-Fi service data. The first identification information is used to identify communication resource information required by STA 101 for the transmission of the device coexistence activity. The third identification information is used to identify time information of the device coexistence activity. The fifth identification information is used to identify an activity type of the device coexistence activity, i.e., a corresponding communication mode of the device coexistence activity. The fourth identification information is used to identify link information of a link in which the device coexistence activity exists.

[0156] In step 202, STA 101 sends the first wireless frame to AP 102. Accordingly, AP 102 receives the first wireless frame sent by STA 101.

[0157] Optionally, AP 102 can be a standalone AP or an affiliated AP of an AP MLD, and the embodiments of the present disclosure do not limit this.

[0158] Optionally, in the case where STA 101 supports multi-link communication and AP 102 supports multi-link communication, i.e., STA 101 is an affiliated STA of a non-AP MLD and AP 102 is an affiliated AP of an AP MLD, STA 101 can send the first wireless frame through a link in which the device coexistence activity exists or through a link in which the device coexistence activity does not exist, and the embodiments of the present disclosure do not limit this.

[0159] Optionally, referring to FIG. 3, in another optional implementation provided by the embodiments of the present disclosure, after step 201 (i.e., STA 101 sends the first wireless frame), the following at least one is further included:

[0160] In step 301a, according to the communication resource information, STA 101 and AP 102 switch to other links to transmit the Wi-Fi service data; wherein the other links do not include a link in which the device coexistence activity is transmitted.

[0161] In step 301b, according to the interference information, STA 101 and AP 102 switch to other channels to transmit the Wi-Fi service data; wherein the other channels do not include a channel in which the device coexistence activity is transmitted.

[0162] Optionally, the step 301a and the step 301b can be determined by negotiation between the STA 101 and the AP 102 after the AP 102 receives the first wireless frame, or can be determined based on a preset manner after the STA 101 sends the first wireless frame; or can be determined based on a preset manner after the AP 102 receives the first wireless frame, and the embodiment of the present disclosure does not limit this.

[0163] Optionally, whether to perform the link switching operation can be determined according to whether the communication resource information required by the STA 101 to transmit the in-device coexistence activity conflicts with the communication resource information required to transmit the Wi-Fi service data. Optionally, in the case that the communication resource information required by the STA 101 to transmit the in-device coexistence activity conflicts with the communication resource information required to transmit the Wi-Fi service data, it is determined that the link switching operation needs to be performed; in the case that the communication resource information required by the STA 101 to transmit the in-device coexistence activity does not conflict with the communication resource information required to transmit the Wi-Fi service data, it can be determined that the link switching operation does not need to be performed.

[0164] Optionally, the other channel can be a non-primary channel under the link of the STA 101 transmitting the Wi-Fi service data and the in-device coexistence activity before the STA 101 sends the first wireless frame. Optionally, when the STA 101 transmits the Wi-Fi service data through the other channel, a non-primary channel access mechanism (NPCA) can be used to switch to the other channel to transmit the Wi-Fi service data.

[0165] Optionally, before switching to the other channel to transmit the Wi-Fi service data according to the interference information, whether the interference caused by the in-device coexistence activity to the transmission process of the Wi-Fi service data can be ignored can be determined based on the interference tolerance indicated by the second identification information carried in the first wireless frame. In the case that the interference tolerance is less than a preset tolerance value, it can be determined that the interference caused by the in-device coexistence activity to the transmission process of the Wi-Fi service data is small, and the interference caused by the in-device coexistence activity to the transmission process of the Wi-Fi service data can be ignored. In the case that the interference tolerance is greater than or equal to the preset tolerance value, it can be determined that the interference caused by the in-device coexistence activity to the transmission process of the Wi-Fi service data is large, and the interference caused by the in-device coexistence activity to the transmission process of the Wi-Fi service data cannot be ignored.

[0166] Optionally, if it is determined that the interference caused by the in-device coexistence activity to the transmission of the Wi-Fi service data is negligible, the channel switching operation or the link switching operation can not be performed; if it is determined that the interference caused by the in-device coexistence activity to the transmission of the Wi-Fi service data is not negligible, the channel switching operation or the link switching operation needs to be further performed.

[0167] Optionally, when determining whether to perform the channel switching operation or the link switching operation, not only the communication resource information indicated by the first identification information carried in the first wireless frame and the interference tolerance indicated by the second identification information carried in the first wireless frame can be relied on, but also other information carried in the first wireless frame can be combined to determine whether to perform the channel switching operation or the link switching operation, specifically:

[0168] (1) If the link for transmitting the Wi-Fi service data by the STA 101 and the link for transmitting the in-device coexistence activity are different before the STA 101 transmits the first wireless frame, the channel or the link does not need to be switched.

[0169] (2) If the link for transmitting the Wi-Fi service data by the STA 101 and the link for transmitting the in-device coexistence activity are the same before the STA 101 transmits the first wireless frame, the channel or the link needs to be switched to transmit the Wi-Fi service data in the case that the communication resource information required by the in-device coexistence activity conflicts with the communication resource information required for transmitting the Wi-Fi service data (i.e., the communication resource required by the in-device coexistence activity is completely or partially the same as the communication resource required for transmitting the Wi-Fi service data). As an example, it is assumed that the STA 101 supports a maximum of four antennas in the 2.4 GHz frequency band or the 5 GHz frequency band, and the STA 101 needs two radio frequency antennas when performing the BT communication and needs four radio frequency antennas when performing the Wi-Fi communication, i.e., the STA 101 shares two radio frequency antennas when performing the BT communication and when performing the Wi-Fi communication. Thus, it can be considered that the communication resource required by the STA 101 to perform the BT communication conflicts with the communication resource required by the STA 101 to perform the Wi-Fi communication.

[0170] (3) If the STA 101 transmits Wi-Fi service data and the device internal coexistence activity on the same link before the STA 101 sends the first wireless frame, the communication resource information required for the device internal coexistence activity does not conflict with the communication resource information required for transmitting the Wi-Fi service data, the time information of the device internal coexistence activity conflicts with the time information of the Wi-Fi service data (that is, the time of the device internal coexistence activity completely or partially overlaps with the time of the Wi-Fi service data), and the interference tolerance is higher than the preset threshold, switching to another link to transmit the Wi-Fi service data.

[0171] (4) If the STA 101 transmits Wi-Fi service data and the device internal coexistence activity on the same link before the STA 101 sends the first wireless frame, the communication resource information required for the device internal coexistence activity does not conflict with the communication resource information required for transmitting the Wi-Fi service data, the time information of the device internal coexistence activity conflicts with the time information of the Wi-Fi service data, and the interference tolerance is less than the preset threshold, not switching to another link to transmit the Wi-Fi service data.

[0172] (5) If the STA 101 transmits Wi-Fi service data and the device internal coexistence activity on the same link before the STA 101 sends the first wireless frame, the communication resource information required for the device internal coexistence activity does not conflict with the communication resource information required for transmitting the Wi-Fi service data, and the time information of the device internal coexistence activity does not conflict with the time information of the Wi-Fi service data, no need to switch the channel or the link.

[0173] Optionally, no need to switch the channel or the link, that is, the channel or the link through which the STA 101 transmits the Wi-Fi service data before sending the first wireless frame can continue to transmit the Wi-Fi service data, and the channel or the link through which the STA 101 transmits the device internal coexistence activity before sending the first wireless frame can continue to transmit the service data corresponding to the device internal coexistence activity.

[0174] Optionally, after the STA 101 and the AP 101 switch to another link, the Wi-Fi service data can be transmitted through the other link, and the device internal coexistence activity can be transmitted through the link before the link switching operation.

[0175] Optionally, after the STA 101 and the AP 101 switch to another channel, the Wi-Fi service data can be transmitted through the other channel, and the device internal coexistence activity can be transmitted through the channel before the channel switching operation.

[0176] Optionally, in the embodiments of the present disclosure, if the STA 101 supports multi-link communication, the switching to another link to transmit the Wi-Fi service data includes at least one of the following:

[0177] In the case that the non-AP MLD to which the STA 101 belongs works in the eMLSR (enhanced multi-link single-radio) mode, the Wi-Fi service data is transmitted on the other link after a delay of link switching in the eMLSR mode at least.

[0178] In the case that the non-AP MLD works in the eMLMR (enhanced multi-link multi-radio) mode, the Wi-Fi service data is transmitted on the other link after a delay of link switching in the eMLMR mode at least.

[0179] Optionally, the non-AP MLD working in the eMLSR mode or the eMLMR mode allows the affiliated non-AP STA 101 on one or more links (which can also be referred to as eMLSR links or eMLMR links accordingly) to be in an awake state for a listening operation. Among them, the non-AP STA 101 affiliated to the non-AP MLD working in the eMLSR link performs a listening operation (referred to as the non-AP STA 101 working in the Listening Operation mode in the embodiments of the present disclosure), which can specifically include: performing a clear channel assessment (CCA) on the eMLSR link where the non-AP STA 101 is located, and detecting whether there is an initial control frame initiated by an AP MLD associated with the non-AP MLD on the eMLSR link.

[0180] In the case that the non-AP MLD works in the eMLSR mode, the delay of link switching of the non-AP MLD is associated with the eMLSR mode corresponding transition delay (EMLSR Transition Delay), and in general cases, the delay of link switching of the non-AP MLD is greater than or equal to the eMLSR mode corresponding transition delay. Therefore, in the case that the non-AP MLD to which the STA 101 belongs works in the eMLSR mode, the STA 101 can switch to the other link and then transmit the Wi-Fi service data on the other link only after a delay of link switching in the eMLSR mode at least.

[0181] In the case that the non-AP MLD operates in the eMLMR mode, the delay of the non-AP MLD in switching the link is associated with the transition delay corresponding to the eMLMR mode, and in general, the delay of the non-AP MLD in switching the link is greater than or equal to the transition delay corresponding to the eMLMR mode. Therefore, in the case that the non-AP MLD to which the STA 101 belongs operates in the eMLMR mode, the STA 101 can switch to another link and then transmit Wi-Fi service data in the other link only after the delay of the non-AP MLD in switching the link in the eMLMR mode.

[0182] In one embodiment, the actions on the STA or non-AP MLD side can include:

[0183] For IDC service of burst type:

[0184] If the STA or non-AP MLD is the IDC service transmitter, the STA or non-AP MLD can define an initial control frame (such as the first wireless frame) carrying the time length information of the IDC service, and can further carry the required NSS information of the IDC service, and can further carry the interference tolerance information of the IDC service in this link, indicating the maximum value of the IDC service that can be received in this link; in addition, there can be IDC service in Link 1 (Link1) and Wi-Fi service in Link 2 (Link2) at the same time, and the two links are NSTR or eMLSR, eMLMR links, and the STA identifies the IDC service information in Link 1 in Link 2, such as further carrying the Link ID identifier.

[0185] If the STA or non-AP MLD is the IDC service receiver, the operation steps are consistent with the above.

[0186] For IDC service of periodic type

[0187] The STA or non-AP MLD completes the initial association or multi-link establishment with the AP or AP MLD, sends a request frame or notification frame to the AP or non-AP MLD, and carries time information such as the time length, periodic information, etc. of the IDC service (including transmission and / or reception) in the frame, and also carries the required NSS information of the IDC service, and can further carry the interference tolerance information of the IDC service in this link, and if multi-link communication is supported, the information in multiple links can be included in one link, such as Link ID + the foregoing information.

[0188] The action of the AP or AP MLD side can include:

[0189] The AP or AP MLD receives the indication information (such as the first wireless frame) of the STA or non-AP MLD (refer to the action of the STA or non-AP MLD described above), and according to the indication information, the STA (non-AP MLD) and the AP (AP MLD) can negotiate to switch to another link or switch to another channel for wi-fi service transmission (such as NPCA) while communicating IDC service. For example, the non-AP MLD works in eMLSR or eMLMR mode, and when switching to another link, the switching delay to the other link needs to be considered.
