Specifically, site device 101 can be a terminal device or network device with a Wi-Fi chip. Optionally, site device 101 can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.

In some embodiments, the access point device 102 can be an access point for mobile terminals to access a wired network. An AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to an Ethernet network. Specifically, an AP can be a terminal device or network device with a wireless fidelity chip. Optionally, the AP can support various WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.

It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called an Access Point (AP) device, and all other STAs in the network are associated with it. Other sites in the BSS network that are not the central site are called terminals, also known as non-AP STAs; terminals and non-AP STAs are collectively referred to as STAs.

When the communication frequency bands of different communication systems are adjacent, the transmitting operation of one system can interfere with the receiving operation of another. On the other hand, when multiple wireless communication modules coexist, and the physical spacing between their radio frequency (RF) modules is small, simultaneous communication using multiple protocols can cause mutual interference, leading to communication failures or performance degradation. For example, both Wi-Fi and BitTorrent operate in the 2.4 GHz band, and in most communication devices, Wi-Fi and BitTorrent modules share antennas. Therefore, mutual interference exists during Wi-Fi and BitTorrent communication, whether between a single node or multiple nodes. Furthermore, as the bandwidth of wireless communication systems increases, the problem of interference between multiple wireless communication systems within a device becomes more severe, reducing the reliability of data transmission between devices.

For example, when there is intra-device coexistence activity at a non-access point (non-AP) STA, the non-AP STA can enter a power-saving (PS) mode, keeping the Wi-Fi module in a sleep state during this process. PS mode can reduce the power consumption of the non-AP STA to some extent, as its associated access point (AP) buffers its downlink data before transmission, minimizing packet loss. However, this approach has several problems. For instance, a non-AP STA in sleep mode will periodically wake up to monitor whether the AP has buffered downlink data. For example, an STA in sleep mode will listen to the Beacon frame or the Traffic-indication virtual bitmap of the TIM (Traffic Indication Mapping) element in the DTIM (Delivery Traffic Indication Mapping) Beacon frame to determine if the AP has buffered downlink data. In the Traffic-indication virtual bitmap, each bit corresponds one-to-one with the AID of the STA associated with the AP. If a STA in sleep mode receives a TIM element with its corresponding AID bit in the Traffic-indication virtual bitmap set to 1, the STA assumes that the AP has buffered downlink data to send to it. At this time, the STA will switch to active mode and send a PS-Poll frame or trigger frame to the AP, waiting to receive the buffered data sent by the AP. However, due to the long duration of coexistence activities within the device (greater than the Beacon Interval and DTIM Interval), non-AP STAs cannot identify whether there is buffered downlink data and cannot send a power-saving polling (PS-Poll) frame or trigger frame to the AP to receive the buffered data; or, after sending a PS-Poll or trigger frame, non-Wi-Fi communication activities may occur, causing the non-AP STA to be unable to respond to the received downlink data. These situations will lead to excessively large downlink data packets in the AP's cache, increasing cache pressure; on the other hand, multiple retransmissions will result in wasted frequency resources and increased AP power consumption. When the retransmission limit set by the system is exceeded (e.g., dot11QAPMissingAckRetryLimit or dot11ShortRetryLimit), the AP will discard the cached downlink data, resulting in data packet loss.

The vision of next-generation Wi-Fi technology, Ultra High Reliability (UHR), aims to improve the reliability of wireless LAN connections, reduce latency, and lower device-level power consumption. Most UHRs are designed as multi-link devices (MLDs). Enhanced signaling and processes are needed to achieve timely and efficient management of interaction and interference between coexisting activities within UHR devices, avoiding interference from multiple communication activities while simultaneously reducing device power consumption.

Figure 2 is one of the interactive schematic diagrams of a method for coexisting activities within a processing device according to an embodiment of the present disclosure. As shown in Figure 2, the method includes steps 201 and 202.

In step 201, the first device receives a first radio frame from the second device; wherein the first radio frame includes a first portion of a transmission opportunity (first portion TXOP) held by the second device and shared with the first device.

According to embodiments of this disclosure, the first device refers to a device with in-device coexistence activities, specifically a non-AP STA (e.g., site device 101 in FIG. 1, hereinafter also referred to as the first STA); the second device is a TXOP holder, specifically an AP (e.g., access point device 102 in FIG. 1, hereinafter also referred to as the second AP). According to embodiments of this disclosure, the first wireless frame may refer to a MU-RTS (multi-user request to send) TXS (triggered TXOP sharing) trigger frame. According to embodiments of this disclosure, in-device coexistence activities in the first device refer to non-Wi-Fi communication activities existing within the first device.

According to embodiments of this disclosure, the AP, as the TXOP holder, sends a MU-RTS TXS trigger frame to its associated first STA within the first TXOP. The MU-RTS TXS trigger frame is used to share a first portion of the TXOP with the first STA, enabling the first STA to perform uplink transmissions or point-to-point (P2P) transmissions to other STAs within the BSS within the shared first portion of the TXOP. According to embodiments of this disclosure, for example, but not limited to, the first portion of the TXOP shared by the second device may be carried in the Allocation Duration field of the User Info field (HE variant/EHT variant/UHR variant) of the first radio frame (MU-RTS TXS trigger frame).

However, the embodiments regarding the first radio frame are not limited thereto. For example, the first radio frame, which is the MU-RTS TXS trigger frame, may also include a protected transmission opportunity, which may be carried in the Duration field of the first radio frame (MU-RTS TXS trigger frame) to identify the transmission of subsequent frames within this protected txop.

In step 202, the first device can determine first information. Specifically, the first device can determine the first information based on the existence of in-device coexistence activities. For example, but not limited to, the first information includes power management mode information and one of the following: a first duration of the first portion of the transmission opportunity required by the first device, and a second duration of the first device being in in-device coexistence activities. According to embodiments of this disclosure, the existence of in-device coexistence activities can refer to the duration of the in-device coexistence activities, for example, including, but not limited to, the first device not having in-device coexistence activities in the first portion of the TXOP but having in-device coexistence activities in the first TXOP, the first device having in-device coexistence activities in the first portion of the TXOP, or the first device not having in-device coexistence activities in the first TXOP. Internal coexistence activities. Depending on the nature of the internal coexistence activities, the first information may include different content. These will be described in detail later with reference to Figures 3 through 5.

In step 203, the first device may send a second wireless frame to the second device, wherein the second wireless frame may include the first information determined in step 202 above. The second wireless frame may be a response frame to the first wireless frame, such as, but not limited to, a CTS (Clear to Send) frame.

According to embodiments of this disclosure, a first device can determine the information included in a second radio frame differently based on the presence of coexisting activities within the device, according to a first portion of TXOP. A more detailed description will follow with reference to Figures 3 to 5.

Figure 3 is a second exemplary interactive schematic diagram of the method provided according to an embodiment of the present disclosure.

Referring to Figure 3, the first device and the second device can be similar to the first device and the second device in Figure 2, respectively. The third device can be a device capable of P2P transmission with the first device (non-AP STA), or it can be a device other than the first device associated with the AP (non-AP STA).

Referring to FIG3, in step 301, the first device can receive a first wireless frame from the second device, wherein the first wireless frame includes a first portion of the TXOP held by the second device that is shared with the first device. The operation of step 301 can be similar to step 201 described above with reference to FIG2; for simplicity, repeated descriptions are omitted here. According to embodiments of this disclosure, for example, but not limited to, the first wireless frame can be an MU-RTS TXS trigger frame, and the first portion of the TXOP can be identified by the Allocation Duration field of the User Info field in the MU-RTS TXS trigger frame. However, this disclosure is not limited thereto; the first wireless frame can be any other frame capable of carrying the required information, and other fields can be used to identify the first portion of the TXOP.

In step 302, based on the existence of coexisting activities within the device (the first device has no IDC activity within the first TXOP but has IDC activity within the first TXOP), the first device can determine first information, which includes first duration and power management mode information. In step 303, the first device can send a second radio frame carrying the first information (first duration and power management mode information) to the second device. According to embodiments of this disclosure, fields in the second radio frame can be used to identify the first duration and power management mode information. For example, the first duration can be identified by the duration field in the second radio frame, and the power management mode information can be identified by the power management field in the second radio frame. However, this disclosure is not limited to this, and other fields can be used to identify the second duration and power management mode information respectively.

For example, in step 302, the first device may set a first duration based on one or more of the following: a first portion TXOP, a protected transmission opportunity included in the first radio frame, the time of receiving the first radio frame, the time of completing the transmission of the second radio frame, and the start time of in-device coexistence activity. The first duration identifies the duration required by the first device in the first portion TXOP. In one embodiment of this disclosure, the first device may set the first duration based on the protected transmission opportunity included in the first radio frame, the time of receiving the first radio frame, the time of completing the transmission of the second radio frame, and the start time of in-device coexistence activity. In another embodiment of this disclosure, the first device may set the first duration based on the first portion TXOP, the time of receiving the first radio frame, and the time of completing the transmission of the second radio frame. However, this disclosure is not limited thereto.

According to an embodiment of this disclosure, in step 302, the power management mode information can be set to a first value by the first device, wherein the first value indicates that the first device enters active mode after sending the second radio frame (step 303) (step 304).

According to embodiments of this disclosure, taking a first device as a first STA and a second device as an AP as an example, the following description is provided:

If the first STA has no intra-device coexistence activity within the shared first part of the TXOP but does have intra-device coexistence activity within the first TXOP, then after receiving the first radio frame (MU-RTS TXS trigger frame), the first STA responds by sending a second radio frame to the AP at an interval of one SIFS (Short interframe space). Key parameters of the second radio frame may include a duration field and a power management field. According to embodiments of this disclosure, the duration field of the second radio frame may refer to the aforementioned first duration, which is set based on the protected transmission opportunities included in the first radio frame, the time between receiving the first radio frame and sending the second radio frame, and the start time of the intra-device coexistence activity. For example, but not limited to, the protected transmission opportunities included in the first radio frame may be identified in the duration field of the MU-RTS TXS trigger frame. As a non-limiting embodiment, the Duration field (first duration) in the second radio frame can be set to: the Duration field value (protected transmission opportunity) in the MU-RTS TXS trigger frame - the time between receiving the last PPDU of the MU-RTS TXS trigger frame and transmitting the last PPDU of the CTS frame - the start time of the in-device coexistence activity of the first STA. According to another embodiment of this disclosure, the Duration field of the second radio frame can refer to the aforementioned first duration, which is set based on the first portion TXOP included in the first radio frame, the time between receiving the first radio frame and transmitting the second radio frame. For example, but not limited to, the first portion TXOP included in the first radio frame can be identified in the Allocation Duration field of the User Info field in the MU-RTS TXS trigger frame. As a non-limiting embodiment, the Duration field (first duration) in the second radio frame can be set to: the Allocation Duration field value (first part TXOP) in the MU-RTS TXS trigger frame - the time between receiving the last PPDU of the MU-RTS TXS trigger frame and transmitting the last PPDU of the CTS frame. According to embodiments of this disclosure, the method for setting the first duration is not limited to this; for example, SIFS and/or PFIS (point coordinate function) can also be considered when setting the first duration. Inter-frame spacing (point coordination function inter-frame interval). For example, but not limited to, the Duration field (first duration) in the second radio frame can be set to: the Allocation Duration field value in the MU-RTS TXS trigger frame (first part TXOP) - the time between receiving the last PPDU of the MU-RTS TXS trigger frame and sending the last PPDU of the CTS frame - SIFS.

According to embodiments of this disclosure, the Power Management field may refer to the aforementioned power management mode information. According to embodiments of this disclosure, the Power Management field in the second radio frame may be set to a first value indicating an active mode (e.g., but not limited to, 0).

Since the first device obtained the shared first portion of the TXOP from the second device in step 301, and there was no intra-device coexistence activity within the first portion of the TXOP, the first device can enter an active mode capable of data transmission (step 304) after sending the second radio frame (step 303). The first duration determined in step 302 can refer to the duration of active mode or data transmission. In active mode, the first device can perform uplink data transmission to the second device or P2P data transmission to the third device (step 305). That is, after sending the second radio frame, the first device is in active mode to perform data transmission until the end of the first duration.

The second device can determine, based on the first duration and power management mode information in the received second radio frame, that the first device has no intra-device coexistence activity within the shared first portion of the TXOP, but does have intra-device coexistence activity within the first TXOP. In this case, except for the occurrence of the first event, the second device may not send any data to the first device within the first portion of the TXOP (or more specifically, within the first duration). As a non-limiting embodiment, the first event includes one or more of the following:

The second device receives the response request from the first device;

The second device detected that the channel was idle;

The second device confirms that the first device sent the last frame.

For example, if a second device (e.g., an AP) receives a response request from a first device within the first TXOP (or more specifically within the first duration), the second device may send data to the first device.

For example, but not limited to, if the second device (e.g., AP) detects that the channel is idle after a TxPIFS time elapses after receiving a frame sent by the first device, the second device (e.g., AP) may send data to the first device.

For example, but not limited to, if a second device (e.g., an AP) receives a frame from a first device (first STA) containing a command and status (CAS) control field, and the RDG/More PPDU field in the CAS control field is set to a specific value (e.g., 0), then the second device (e.g., the AP) acknowledges that the first STA has sent the last frame. In this case, if the second device (e.g., the AP) has data that needs to be sent to the first STA, it can then send it.

Referring again to Figure 3, in step 306, the first duration ends. Since the first device (first STA) has no intra-device coexistence activity within the shared first portion of the TXOP but does have intra-device coexistence activity within the first TXOP, then in step 307, the first device enters a doze state. Since the first device has no IDC activity within the first portion of the TXOP but does have IDC activity within the first TXOP, after the first duration ends, the first device may need to start non-Wi-Fi communication. To avoid interference, the first device's Wi-Fi module enters a doze state.

In step 308, after the first TXOP of the sharing ends, the first duration ends, or after receiving a transmission end indication sent by the first device, the second device (AP) sends a PPDU to a third STA associated with the second device (AP) at a specific time interval (e.g., PFIS). The third STA does not include the first STA.

Although Figure 3 shows that the device that performs P2P transmission with the first device in step 305 and the device to which the second device sends PPUD in step 308 are both the same third device, this is for the sake of simplicity in the figures. According to the embodiments of this disclosure, the third device in steps 305 and 308 may refer to different devices.

Figure 4 is a third exemplary interactive schematic diagram of the method provided according to an embodiment of the present disclosure.

Referring to Figure 4, the first device and the second device can be similar to the first device and the second device in Figure 2, respectively. The third device can be a device capable of P2P transmission with the first device (non-AP STA), or it can be a device other than the first device associated with the AP (non-AP STA).

Referring to Figure 4, in step 401, the first device can receive a first wireless frame from the second device, wherein the first wireless frame includes a first portion of the TXOP held by the second device that is shared with the first device. The operation of step 401 can be similar to step 201 described above with reference to Figure 2 and step 301 in Figure 3; for the sake of brevity, repeated descriptions are omitted here.

In step 402, based on the coexistence activities of the first device within the first part TXOP, first information is determined, which includes second duration and power management mode information. In step 403, the first device may send a second radio frame carrying the first information (second duration and power management mode information) to the second device.

For example, in step 402, the first device sets the second duration based on the duration of coexisting activities within the device. For example, in In step 402, the power management mode information can be set to a second value by the first device, indicating that the first device enters a sleep state (Doze state) after sending the second wireless frame (step 403) (step 404).

According to embodiments of this disclosure, taking a first device as a first STA and a second device as an AP as an example, the following description is provided: If the first STA has in-device coexistence activity within the shared first part TXOP, the first STA, after receiving a first radio frame (MU-RTS TXS trigger frame), sends a second radio frame to the AP at an interval of, for example, one SIFS to respond. Key parameters of the second radio frame may include a duration field and a power management field. According to embodiments of this disclosure, the duration field of the second radio frame may refer to the aforementioned second duration. For example, the value of the duration field of the second radio frame may be set to: the duration of the in-device coexistence activity of the first STA. According to embodiments of this disclosure, the method of setting the duration field in the second radio frame is not limited to this; for example, the value of the duration field may be set considering SIFS and/or PFIS. According to embodiments of this disclosure, the power management field in the second radio frame may be set to a second value indicating a sleep state (e.g., but not limited to, 1).

Since in step 401, although the first device obtains the shared first part of TXOP from the second device, there is coexistence activity within the device in the first part of TXOP, the first device can put its Wi-Fi module into a sleep state (step 404) after sending the second wireless frame (step 403) to avoid interference.

In step 405, the second device may send data to its associated third device. Based on the first information (second duration and power management mode information) in the second radio frame, the second device may determine that the first device has intra-device coexistence activity during the second duration, and the second device will not send any data to the first device during the second duration indicated in the second radio frame, but may send data to its associated third device. Step 405 is merely exemplary; for example, if the AP and other associated third devices do not have corresponding services, step 405 may be omitted from Figure 4.

According to embodiments of this disclosure, taking a first device as a first STA and a second device as an AP as an example, the following description is provided: the AP does not send any PPDU to the first STA during the time (second duration) indicated by the Duration field in the second radio frame, but may send PPDU to other STAs associated with it, which does not include the first STA.

In this way, the second device can determine the duration of the coexistence activity within the first device based on the first information provided by the second wireless frame, thereby avoiding Wi-Fi communication with the first device during that duration to prevent packet loss, data transmission errors or resource waste, while also being able to communicate with other devices besides the first device during that duration to improve communication efficiency.

In step 406, the duration of the in-device coexistence activity (second duration) of the first device ends. That is, after sending the second wireless frame, the first device enters a sleep state until the second duration ends.

In step 407, after the second duration indicated by the second radio frame ends, the second device can send data to the first device and the third device. The end of the second duration indicated by the second radio frame signifies the end of the coexistence activity within the first device, thus allowing the first device to wake up from its sleep state, and enabling the second device to send data to the first device.

According to embodiments of this disclosure, taking a first device as a first STA and a second device as an AP as an example, the following description is provided: After the second duration indicated by the Duration field in the second radio frame ends, after an interval such as one PFIS, the AP may send a PPDU to its associated third STA, which may include the first STA and/or other STAs.

Although not shown, after step 406, the first device (first STA) can also transmit data with other STAs. Although Figure 4 shows that the device transmitting data with the second device in steps 405 and 406 is the same third device, this is for simplification of the figures. According to embodiments of this disclosure, the third device in steps 405 and 406 may refer to different devices.

Figure 5 is a fourth exemplary interactive schematic diagram of the method provided according to embodiments of this disclosure.

Referring to Figure 5, the first device and the second device can be similar to the first device and the second device in Figure 2, respectively. The third device can be a device capable of P2P transmission with the first device (non-AP STA), or it can be a device other than the first device associated with the AP (non-AP STA).

Referring to Figure 5, in step 501, the first device can receive a first wireless frame from the second device, wherein the first wireless frame includes a first portion of the TXOP held by the second device that is shared with the first device. The operation of step 501 can be similar to steps 201 described above with reference to Figure 2 and steps 301 in Figure 3; for the sake of brevity, repeated descriptions are omitted here.

In step 502, the first device can determine first information, including a third duration and power management mode information, based on the absence of in-device coexistence activity within the first TXOP. In step 503, the first device can send a second radio frame carrying the first information (third duration and power management mode information) to the second device. For example, the third duration indicates the duration required for the first device to transmit data. The third duration is determined by the first device based on the protected TXOP included in the first radio frame (e.g., the value of the Duration field in the MU-RTS TXS trigger frame), the time of receiving the first radio frame, and the time of completing the transmission of the second radio frame. For example, power management... The mode information can be set to a first value, indicating that the first device is in active mode after sending the second radio frame.

According to embodiments of this disclosure, taking a first device as a first STA and a second device as an AP as an example, the following description is provided: If there is no in-device coexistence activity within the first TXOP, then after receiving the first radio frame (MU-RTS TXS trigger frame), the first STA responds by sending a second radio frame (e.g., a CTS frame or a variant of CTS) to the AP at intervals such as one SIFS. Key parameters of the second radio frame may include a duration field and a power management field. According to embodiments of this disclosure, the duration field may refer to the aforementioned third duration, which is set by the first STA based on the protected TXOP included in the first radio frame and the time between receiving the first radio frame and sending the second radio frame. For example, the duration field (third duration) in the second radio frame may be set to, but is not limited to: the duration field value (protected TXOP) in the MU-RTS TXS trigger frame (first radio frame) - the time between receiving the last PPDU of the MU-RTS TXS trigger frame and sending the last PPDU of the CTS frame (second radio frame). According to embodiments of this disclosure, the method for setting the third duration is not limited to this; for example, SIFS and/or PFIS may also be considered when setting the third duration. According to embodiments of this disclosure, the Power Management field may represent the power management mode information of step 502 above. According to embodiments of this disclosure, the Power Management field in the second radio frame may be set to a first value indicating an active mode (e.g., but not limited to, 0).

In step 504, since there is no intra-device coexistence activity in the first TXOP, the first device can be in active mode, and in step 505, the first device can, for example, transmit uplink data to the second device or transmit P2P data to the third device within the third duration.

The second device can determine, based on the first information (third duration and power management mode information) in the received second radio frame, that the first device has no intra-device coexistence activity within the first TXOP. Since the first portion of the TXOP has been shared with the first device, in this case, the second device may not send any data to the first device within the first portion of the TXOP (or more specifically, within the third duration), except in the event of the second event. As a non-limiting embodiment, the second event includes one or more of the following:

The second device receives the response request from the first device;

The second device detected that the channel was idle;

The second device confirms that the first device sent the last frame.

For example, if a second device (e.g., an AP) receives a response request from a first device within the first TXOP (or more specifically within the third duration), the second device (e.g., the AP) can send data to the first device.

For example, but not limited to, if the second device (e.g., AP) detects that the channel is idle after a TxPIFS time elapses after receiving a frame sent by the first device, the second device (e.g., AP) may send data to the first device.

For example, but not limited to, if a second device (e.g., an AP) receives a frame from a first device (e.g., a first STA) containing a command and status (CAS) control field, and the RDG/More PPDU field in the CAS control field is set to a specific value (e.g., 0), then the second device (e.g., the AP) acknowledges that the first STA has sent the last frame. In this case, if the second device (e.g., the AP) has data that needs to be sent to the first STA, it can then send it.

After the first TXOP of the shared data ends, the third duration ends, or the second device (AP) receives a transmission end indication from the first device (step 506), the second device (AP) sends a PPDU to the device associated with the second device (AP) at a specific time interval (e.g., PFIS) (step 507). The device may include the first device and/or a third device associated with the AP other than the first device. Although Figure 5 shows that the device performing P2P transmission with the first device in step 505 and the device to which the second device sends the PPDU in step 507 are the same third device, this is for simplification of the figures. According to embodiments of this disclosure, the third device in steps 505 and 507 may refer to different devices.

According to the method for handling coexistence activities within a device disclosed herein, the non-AP STA indicates coexistence activities within the device based on whether coexisting non-Wi-Fi communication activities exist and the timing of these activities, during the TXOP sharing process in response to the AP. On one hand, the non-AP STA can determine whether to enter a corresponding sleep state based on the sharing time and the timing of the non-Wi-Fi communication activity; on the other hand, the AP selectively performs TXOP sharing based on the non-AP STA's response. Based on this method, indication and interference cancellation of coexistence activities within the device can be achieved, improving transmission reliability while reducing the power consumption of the non-AP STA and/or the AP.
