[0001] Cross Reference to Related Applications

[0002] This application claims priority to the Chinese Patent Application No. 202410999454.8, filed on July 23, 2024, and entitled "A communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the technical field of wireless communication, and in particular to a communication method and apparatus. BACKGROUND

[0004] At present, domestic wireless fidelity (Wi-Fi) devices only allow to work in 2.4GHz, 5.4GHz, 5.8GHz frequency bands, and support maximum 160MHz bandwidth transmission. Although the Wi-Fi protocol supports maximum 320MHz bandwidth transmission, the use of 6GHz frequency band is limited in China, and therefore the domestic Wi-Fi devices do not support 320MHz bandwidth transmission. Facing the future, Wi-Fi devices can be expanded to support 6-9GHz frequency bands, such as the ultra wide band (UWB) frequency band with a frequency range of 7163-8812MHz. For ease of description, the Wi-Fi device supporting 6-9GHz frequency bands is referred to as an extended Wi-Fi device, and the signal transmitted by the extended Wi-Fi device in the 6-9GHz frequency band is referred to as an extended Wi-Fi signal.

[0005] The extended Wi-Fi device can also support technologies such as sparklink positioning (SLP) and UWB. Among them, the bandwidth of the signal transmitted in the technologies such as SLP and UWB is similar to that of the extended Wi-Fi signal. Therefore, when the extended Wi-Fi device works in the 6-9GHz frequency band, it is urgent to solve the coexistence problem of the extended Wi-Fi signal and other protocol signals. SUMMARY

[0006] The present application provides a communication method and apparatus to reduce mutual interference between signals.

[0007] In a first aspect, a communication method is provided. The method can be performed by a first communication device. In the present disclosure, the first communication device can refer to an access point or a non-access point station, a component (e.g., a processor, a chip, or a chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. The method includes determining, by the first communication device, at least two first time domain resource units, the at least two first time domain resource units being used to carry a first signal. The first signal is a signal of a first communication protocol, and a frequency domain resource carrying the first signal corresponds to a first frequency band. The first communication device transmits a second signal on a second time domain resource unit. When an interval between the at least two first time domain resource units is less than a first threshold, a frequency domain resource carrying the second signal corresponds to a second frequency band. Or, when the interval between the at least two first time domain resource units is greater than or equal to the first threshold, the frequency domain resource carrying the second signal corresponds to the first frequency band, and the second time domain resource unit does not overlap with the at least two first time domain resource units. The second signal includes at least one signal satisfying a Wi-Fi protocol.

[0008] Based on the above scheme, the first communication device can determine whether the first signal and the second signal are time-division or frequency-division based on the interval between the at least two first time domain resource units, thereby reducing the interference between the first signal and the second signal. In addition, if the interval between the at least two first time domain resource units is greater than or equal to the first threshold, it can be considered that the interval between the at least two first time domain resource units can satisfy the transmission of the second signal, so that the second signal can be transmitted on the first frequency band, so that the first communication device can support working on the first frequency band, such as 6-9 GHz.

[0009] In a second aspect, a communication method is provided. The method can be performed by a first communication device. In the present disclosure, the first communication device can refer to an access point or a non-access point station, a component (e.g., a processor, a chip, or a chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. The method includes determining, by the first communication device, at least two first time domain resource units, the at least two first time domain resource units being used to carry a first signal. The first signal is a signal of a first communication protocol, and a frequency domain resource carrying the first signal corresponds to a first frequency band. The first communication device transmits a second signal on a second time domain resource unit. The frequency domain resource carrying the second signal corresponds to a second frequency band, and the second signal includes at least one signal satisfying a Wi-Fi protocol.

[0010] Based on the above scheme, the first communication device can fall back to the second frequency band to transmit the second signal when the first signal is transmitted on the first frequency band, so that the first signal and the second signal are frequency-division, and the interference between the first signal and the second signal is reduced.

[0011] In a possible implementation of the first aspect and the second aspect, the at least two first time domain resource units are determined based on one or more of a service type corresponding to the first signals, an interval between the at least two first signals, or a time length corresponding to the first signals.

[0013] In a possible implementation of the first aspect and the second aspect, the second time domain resource unit is determined according to one or more of a service priority corresponding to the second signal or a transmission time length corresponding to the second signal.

[0014] Based on the above scheme, the first communication device can determine the second time domain resource unit according to the service priority, so that the high-priority service can be transmitted preferentially. In addition, the first communication device can also determine the second time domain resource unit according to the transmission time length corresponding to the second signal, so that the first communication device can determine whether the interval between the at least two first time domain resource units can meet the transmission of the second signal.

[0081] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0082] The embodiments of this application can be applied to local area networks (LANs), particularly wireless local area networks (WLANs), such as WLANs employing any of the protocols in the IEEE 802.11 series. The WLAN may include one or more basic service sets (BSSs), and the network nodes in the BSSs include access points (APs) and stations (STAs). The embodiments of this application can also be applied to wireless local area network systems that support IEEE 802.11ax next-generation wireless fidelity (Wi-Fi) protocols, such as 802.11be, Wi-Fi 7, or extremely high throughput (EHT), such as 802.11be next generation, Wi-Fi 8, ultra high reliability (UHR, 802.11bn), Wi-Fi AI, and other 802.11 series protocols. They can also be applied to wireless personal area network systems and sensing systems based on ultra wide band (UWB).

[0083] The embodiments of this application can also be applied to wireless local area networks such as Internet of Things (IoT) networks or vehicle-to-X (V2X) networks. Of course, the embodiments of this application can also be applied to other possible communication systems, such as long term evolution (LTE) communication systems, LTE frequency division duplex (FDD) communication systems, LTE time division duplex (TDD) communication systems, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication systems, 5th generation (5G) communication systems, or future evolutionary communication systems (such as 6th generation (6G) communication systems).

[0084] The following example uses an embodiment of this application to illustrate a WLAN. Referring to Figure 1, which is a network architecture diagram of a WLAN applicable to an embodiment of this application, Figure 1 shows an example of a WLAN including one AP and two STAs, with each STA being a mobile phone. The STA associated with the AP can receive frames (e.g., trigger frames) sent by the AP and can also send frames (e.g., uplink data) to the AP. This embodiment of the application can be applied to communication between APs and STAs, or it can be applied to communication between APs, for example, APs can communicate with each other through a distributed system (DS). Alternatively, this embodiment of the application can also be applied to communication between STAs, for example, STAs can communicate directly without going through an AP. In this embodiment of the application, the number of APs performing communication can be one or more, and the number of STAs performing communication can be one or more.

[0085] An access point (AP) can be an access point for terminal devices to access a wired (or wireless) 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. For example, an AP can be a terminal device (such as a mobile phone) or a network device (such as a router) with a mobile hotspot (Wi-Fi) chip. In this embodiment, the AP can be a device supporting the 802.11be standard, or it can be a device supporting various WLAN standards such as 802.11ax, 802.11ay, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11be, 802.11bn, and future 802.11 series.

[0086] A STA can be a wireless communication chip, wireless sensor, or wireless communication terminal, and can also be referred to as a user. For example, a STA can be a mobile phone supporting Wi-Fi communication, a tablet computer supporting Wi-Fi communication, a set-top box supporting Wi-Fi communication, a smart TV supporting Wi-Fi communication, a smart wearable device supporting Wi-Fi communication, an in-vehicle communication device supporting Wi-Fi communication, or a computer supporting Wi-Fi communication. Optionally, the STA can support the 802.11be standard, or it can also support various WLAN standards such as 802.11ax, 802.11ay, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, or 802.11be, 802.11bn, and future 802.11 series.

[0087] The number of APs and STAs shown in Figure 1 is just an example; there could be more or fewer.

[0088] In this application embodiment, the number of nouns, unless otherwise specified, refers to "singular nouns or plural nouns," that is, "one or more." "At least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. For example, A / B means: A or B. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c means: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple.

[0089] The ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the size, content, order, timing, priority, or importance of the multiple objects. For example, the first type and the second type can be the same type or different types, and such names do not indicate that the two types correspond to different devices, application scenarios, priorities, or importance. In addition, the numbering of steps in the various embodiments described in this application is only to distinguish different steps and is not used to limit the order of steps.

[0090] In the embodiments of this application, "signals that satisfy the Wi-Fi protocol" may refer to signals with different frequency bands and those defined by the Wi-Fi protocol, or signals with the same signal format, interaction parameters, etc. as those defined by the Wi-Fi protocol.

[0091] Currently, domestic Wi-Fi devices are only allowed to operate in the 2.4GHz, 5.4GHz, and 5.8GHz frequency bands, with a maximum supported bandwidth of 160MHz. Although the Wi-Fi protocol supports a maximum bandwidth of 320MHz, the 6GHz band is restricted in China, therefore domestic Wi-Fi devices do not support 320MHz bandwidth transmission. Future-oriented Wi-Fi devices can be extended to support the 6-9GHz frequency band, such as the UWB band with a frequency range of 7163-8812MHz. For ease of description, in this application embodiment, Wi-Fi devices supporting the 6-9GHz frequency band are referred to as extended Wi-Fi devices, and the signals transmitted by extended Wi-Fi devices in the 6-9GHz frequency band are referred to as extended Wi-Fi signals. When extended Wi-Fi devices operate in the UWB band, the transmitted signals must comply with the radio management regulations of the corresponding frequency band. Taking the UWB band as an example, the bandwidth (-10dB bandwidth) is not less than 500MHz, the equivalent isotropic radiated power spectral density limit is not greater than -41dBm / MHz, and the out-of-band transmit power limit is shown in Table 1 below.

[0092] Extended Wi-Fi devices can also support technologies such as SLP and UWB. The transmission bandwidth of SLP and UWB technologies is similar to that of extended Wi-Fi signals. Therefore, when extended Wi-Fi devices operate in the 6–9 GHz frequency band, it is crucial to address the coexistence issue between extended Wi-Fi signals and other protocol signals.

[0093] In one possible implementation, the first and / or second communication devices involved in this application embodiment can be the communication device shown in FIG2. As shown in FIG2, the communication device may include a Wi-Fi module, which may support unlicensed frequency bands, such as 2.4GHz, 5.1GHz, 5.8GHz, and 6GHz bands, and may also support the 6-9GHz band. Optionally, the Wi-Fi module may also be called an extended Wi-Fi module. The communication device may also include other communication modules, such as an SLP module or a UWB module. The communication device may also include a low-power module, such as Bluetooth Low Energy (BLE) or Sparklink Low Energy (SLE) access technology. Since there is no synchronization / coexistence scheduling module in this communication device, the extended Wi-Fi module cannot coexist with other communication modules.

[0094] In another possible implementation, the first and / or second communication devices involved in this application embodiment can be the communication device shown in FIG3. As shown in FIG3, the communication device may include a Wi-Fi module, which may support unlicensed frequency bands, such as 2.4GHz, 5.1GHz, 5.8GHz, and 6GHz bands, and may also support the 6-9GHz band. Optionally, the Wi-Fi module may also be called an extended Wi-Fi module. The communication device may also include other communication modules, such as an SLP module or a UWB module. Because a coexistence (COEX) module exists in this communication device, the extended Wi-Fi module and other communication modules can coexist through the COEX module.

[0095] Therefore, embodiments of this application provide a communication method. The method provided in this application can be applied to the network architecture shown in FIG1, and can be executed by a first communication device and a second communication device. Unless otherwise specified, the "first communication device" in this application can refer to an access point or a non-access point site, or a component (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. Similarly, unless otherwise specified, the "second communication device" in this application can refer to an access point or a non-access point site, or a component (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the second communication device.

[0096] To better illustrate the embodiments of this application, the methods provided by the embodiments of this application are described below with reference to the accompanying drawings. Referring to Figure 4, an exemplary flowchart of a communication method provided by an embodiment of this application is shown, which may include the following steps.

[0097] S401: The first communication device determines at least two first time domain resource units.

[0098] At least two first time-domain resource units can be used to carry a first signal. In this paper, the first signal can be a signal of a first communication protocol, such as an SLP signal or a UWB signal. The frequency domain resource carrying the first signal corresponds to a first frequency band, such as the 6-9 GHz band or the 7163-8812 MHz UWB band.

[0099] In one possible implementation, the first communication device can determine at least two first time-domain resource units (RTUs) based on one or more of the following: the service type corresponding to the first signal, the interval between at least two first signals, or the transmission duration of the first signal. Assuming the first signal is an SLP signal, then the first signal can be a pulse signal. For example, the first communication device can determine the pulse interval of the pulse signal based on the service type, thereby enabling the first communication device to determine at least two RTUs carrying the first signal. Alternatively, the first communication device can determine at least two RTUs based on the interval between at least two first signals, i.e., the pulse interval. Yet another example is that the first communication device can determine at least two RTUs based on the pulse interval and the transmission duration of the pulse signal.

[0100] In some embodiments, if the first communication device is as shown in FIG3, other communication modules may send one or more of the following information to the COEX module: the service type corresponding to the first signal, the interval between at least two first signals, or the transmission duration of the first signal, so that the COEX module can determine at least two first time domain resource units.

[0101] S402: The first communication device sends a second signal on the second time domain resource unit.

[0102] Correspondingly, the second communication device receives the second signal on the second time domain resource unit.

[0103] For example, the extended Wi-Fi module shown in Figures 2 and 3 transmits a second signal on a second time-domain resource unit. In this document, the second signal may include at least one signal that satisfies the Wi-Fi protocol, such as an extended Wi-Fi signal.

[0104] Optionally, the first communication device may send resource indication information to the second communication device to indicate the second time-domain resource unit and the time-frequency resource carrying the second signal, so that the second communication device can receive the second signal on the corresponding time-frequency resource according to the resource indication information.

[0105] In one possible scenario, the frequency domain resource unit carrying the second signal corresponds to the first frequency band, such as the 6–9 GHz band or the 7163–8812 MHz UWB band. The second time domain resource unit does not overlap with at least two first time domain resource units, meaning the first and second signals are transmitted in a time-division manner. For example, the second and first signals can be transmitted in a time-division manner through a predefined protocol to reduce interference between them. For instance, if the first communication device is as shown in Figure 3, then when the extended Wi-Fi module and other communication modules are operating simultaneously in the 6–9 GHz band, the COEX module can schedule the transmission of the first and second signals in a time-division manner to reduce mutual interference.

[0106] In another possible scenario, the frequency band carrying the second signal corresponds to a second frequency band, such as the 2.4GHz, 5.1GHz, 5.8GHz, or 6GHz bands. This means the first communication device can fall back to a frequency-division multiplexing (FDM) transmission method for the first and second signals. For example, this can be achieved through a predefined protocol, allowing the second and first signals to be transmitted via FDM to reduce interference. For instance, if the first communication device is as shown in Figure 2, when the extended Wi-Fi module and other communication modules are operating simultaneously in the 6-9GHz band, the extended Wi-Fi module can switch to other frequency bands, such as the 2.4GHz, 5.1GHz, 5.8GHz, or 6GHz bands, to reduce mutual interference. Therefore, the frequency band carrying the second signal corresponds to the second frequency band.

[0107] In some embodiments, the first communication device (the COEX module shown in FIG3) can determine, based on the interval between at least two first time-domain resource units, whether the frequency-domain resource unit carrying the second signal corresponds to a first frequency band or a second frequency band. In other words, the first communication device can determine, based on the interval between at least two first signals, whether the frequency-domain resource carrying the second signal corresponds to a first frequency band or a second frequency band.

[0108] For example, assume the first signal is an SLP pulse signal. The SLP pulse signal can be used for ranging or angle measurement. Depending on the service scenario, the interval of the SLP pulse signal can be flexibly configured, for example, the pulse interval can vary from 12 to 1000 μs. To enhance coverage, the SLP pulse signal has a short transmission duration and a long transmission interval, transmitted only in a few time slots within 1 ms, as shown in Figure 5. When the SLP pulse signal is used for angle measurement, the SLP sends high-speed, short-interval pulses, as shown in Figure 6.

[0109] Therefore, the first communication device can determine that the frequency domain resources carrying the second signal correspond to the second frequency band when the interval between at least two first time domain resource units is less than a first threshold, or when the interval between at least two first signals is less than the first threshold. In other words, the first communication device can revert to the 2.4GHz, 5.1GHz, 5.8GHz, or 6GHz frequency bands to transmit the second signal, as shown in Figure 7A. Alternatively, the first communication device can determine that the frequency domain resources carrying the second signal correspond to the first frequency band when the interval between at least two first time domain resource units is greater than the first threshold, or when the interval between at least two first signals is greater than the first threshold. However, the second time domain resource units do not overlap with the at least two first time domain resource units; that is, the first and second signals are transmitted in a time-division manner, as shown in Figure 7B.

[0110] It should be noted that when the interval between at least two first time domain resource units is equal to the first threshold, or when the interval between at least two first signals is equal to the first threshold, the frequency domain resource carrying the second signal can correspond to the second frequency band, or the frequency domain resource carrying the second signal can correspond to the first frequency band.

[0111] In one possible implementation, the first communication device can further determine a second time-domain resource unit. For example, the first communication device can determine the second time-domain resource unit based on one or more of the service priority or the transmission duration corresponding to the second signal. For instance, the first communication device can prioritize the transmission of high-priority services, so the second time-domain resource unit corresponding to a higher-priority service can be positioned earlier in the time domain. Alternatively, the first communication device can determine whether the interval between at least two first time-domain resource units can satisfy the transmission duration corresponding to the second signal. If it can, the frequency domain resource carrying the second signal can correspond to the first frequency band; if it cannot, the frequency domain resource carrying the second signal can correspond to the second frequency band. For example, the extended Wi-Fi module can send the service priority or transmission duration to the COEX module, and the COEX module can determine the second time-domain resource unit.

[0112] In this embodiment, the first threshold may be predefined by the protocol, determined by the first communication device, or pre-configured. For example, the first threshold may be determined by the first communication device, which can determine it based on the interval between at least two first time-domain resource units (RTUs) or the interval between at least two first signals, and the duration required for uplink / downlink handover. For instance, the first threshold may be less than or equal to the difference between the interval between at least two RTUs and the duration required for uplink / downlink handover, thereby ensuring that there are sufficient RTUs to transmit the second signal.

[0113] In some embodiments, the first signal can be a periodic signal or an aperiodic signal. If the first signal is an aperiodic signal, then the interval between at least two first signals is uncertain, and therefore the first communication device may need to frequently determine the first time-domain resource unit carrying the first signal. Therefore, for example, the first communication device may not send or receive aperiodic first signals, or the first communication device may only send or receive periodic first signals, thereby reducing the complexity of the first communication device when the first signal and the second signal coexist.

[0114] For example, when the first signal is a non-periodic signal, the frequency domain resources carrying the second signal can correspond to the second frequency band. That is, when the first signal is a non-periodic signal, the first communication device can back down the frequency band to reduce the interference between the first signal and the second signal, and at the same time reduce the complexity of the first communication device.

[0115] For example, when the first signal is a non-periodic signal, the first communication device transmits or receives the first signal on a specific time-domain resource unit, while the frequency-domain resource carrying the second signal can correspond to either the first frequency band or the second frequency band, which can also reduce the complexity of the first communication device. For example, when the first signal is a non-periodic signal, the first communication device transmits the second signal on a specific time-domain resource unit, while the frequency-domain resource carrying the second signal can correspond to either the first frequency band or the second frequency band, which can also reduce the complexity of the first communication device.

[0116] Based on the above scheme, when the extended Wi-Fi device operates in the 6-9 GHz frequency band, the interference between the extended Wi-Fi signal and other protocol signals can be reduced through the scheduling of the first communication device.

[0117] The embodiment shown in Figure 4 above describes a technical solution for the first communication device to transmit a second signal. This application also provides another communication method. This method can be applied to the network architecture shown in Figure 1, and the method provided in this application can be executed by the first communication device and the second communication device. Unless otherwise specified, the "first communication device" in this application can refer to an access point or a non-access point site, or a component (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. Similarly, unless otherwise specified, the "second communication device" in this application can refer to an access point or a non-access point site, or a component (e.g., a processor, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the second communication device.

[0118] Referring to Figure 8, which is an exemplary flowchart of a communication method provided in an embodiment of this application, it may include the following steps.

[0119] S801: The first communication device determines at least two first time domain resource units.

[0120] At least two first time-domain resource units can be used to carry a first signal. In this paper, the first signal can be a signal of a first communication protocol, such as an SLP signal or a UWB signal. The frequency domain resource carrying the first signal corresponds to a first frequency band, such as the 6-9 GHz band or the 7163-8812 MHz UWB band.

[0121] In this embodiment, S801 can be implemented with reference to S401, and will not be described again here.

[0122] S802: The first communication device sends the first radio frame.

[0123] Correspondingly, the second communication device receives the first wireless frame.

[0124] The first radio frame may include indication information for a second time-domain resource element. Alternatively, the first radio frame may include indication information for a third and / or a fourth time-domain resource element. The following describes different scenarios.

[0125] Case 1: The first radio frame includes indication information for the second time domain resource element.

[0126] In this scenario, the second time-domain resource unit can be used to receive the second signal, and the frequency-domain resource carrying the second signal can correspond to the second frequency band. In other words, in this case, the first and second signals can be transmitted via frequency division.

[0127] In one possible implementation, the first communication device can actively detect signals from the same or different systems, such as Wi-Fi, SLP, or radar signals, in the second frequency band to determine interference information, and determine the second time-domain resource unit based on the interference information. For example, if the first communication device is as shown in Figure 3, the extended Wi-Fi module and other communication modules can actively detect signals in the second frequency band to determine the interference information. The extended Wi-Fi module and other communication modules can then send the determined interference information to the COEX module, which will then determine the second time-domain resource unit.

[0128] In this embodiment, the second time-domain resource unit may include available time-domain resource units and / or unavailable time-domain resource units. Available time-domain resource units can be understood as resource units capable of receiving the second signal, and unavailable time-domain resource units can be understood as resource units that cannot be used to receive the second signal.

[0129] If the first communication device is a non-access point site device, then the second communication device can be an access point site device. The first communication device can send a first radio frame to the second communication device to indicate available and / or unavailable time-domain resource units, thereby allowing the second communication device to determine the time-domain resource unit for transmitting the second signal, such as the fifth time-domain resource unit. The fifth time-domain resource unit may be some or all of the available time-domain resource units. In one possible scenario, the second communication device can indicate the fifth time-domain resource unit to the first communication device, thereby allowing the first communication device to receive the second signal in the fifth time-domain resource unit. For example, the second communication device can broadcast resource unit allocation information, and the first communication device can receive the resource unit allocation information broadcast by the second communication device, thereby determining that the resource unit allocated by the second communication device to the first communication device is the fifth time-domain resource unit.

[0130] In some embodiments, the first wireless frame may include a bitmap to indicate available and / or unavailable time-domain resource units (TRPs) of the first communication device. For example, the first wireless frame may carry a field with N bits, dividing the target time period into N TRPs. Each bit of this field corresponds to a transmission time slot. Setting the nth bit to 1 indicates that the nth TRP is available within the target time period, and setting the nth bit to 0 indicates that the nth TRP is unavailable within the target time period.

[0131] Optionally, the second communication device may also receive indications of available and / or unavailable time domain resource units from other associated non-access point site devices, as well as other indications of available and / or unavailable time domain resource units for associated non-access point site devices. In this way, the second communication device can reallocate time domain resource units for receiving or transmitting for different non-access point site devices. The aforementioned resource unit allocation information may include the reallocation of time domain resource units for receiving or transmitting for different non-access point site devices.

[0132] In one example, if the first communication device is an access point site device, then the second communication device can be a non-access point site device. The first communication device can send a first radio frame to the second communication device, indicating available and / or unavailable time domain resource units. The second communication device can then send a second signal on an available time domain resource unit, such as the fifth time domain resource unit, and the first communication device can receive the second signal on the fifth time domain resource unit. Exemplarily, the first communication device can broadcast the first radio frame, and the second communication device can receive the broadcast second radio frame. Optionally, the second communication device can engage in channel contention to send the second signal on the fifth time domain resource unit. In one possible scenario, the first radio frame may include a bitmap to indicate available and / or unavailable time domain resource units, which will not be elaborated further here.

[0133] In another example, if the first communication device is an access point site device, then the first radio frame can instruct the first communication device to allocate a time-domain resource unit (TLU) to the second communication device for transmitting a second signal. In other words, in this scenario, the second TLU can be a TLU allocated by the first communication device to the second communication device for transmitting the second signal. The second communication device can transmit the second signal on the second TLU, and the first communication device can receive the second signal on the second TLU.

[0134] Optionally, the first communication device may also receive indications of available and / or unavailable time-domain resource elements from other associated non-access point site devices, as well as other indications of available and / or unavailable time-domain resource elements for associated non-access point site devices. In this way, the first communication device can reallocate time-domain resource elements for receiving or transmitting for different non-access point site devices. The first radio frame may include the first communication device's reallocation of time-domain resource elements for receiving or transmitting for different non-access point site devices.

[0135] Based on the above scheme, the first communication device can reduce mutual interference by using a backoff method to frequency-divide the first signal and the second signal.

[0136] Case 2: The first radio frame includes indication information for the third time domain resource element and / or the fourth time domain resource element.

[0137] In this scenario, the third time-domain resource element can be used to receive signals and does not overlap with at least two first time-domain resource elements, while the fourth time-domain resource element can overlap with at least two first time-domain resource elements. In other words, the third time-domain resource element can be understood as an available time-domain resource element, and the fourth time-domain resource element can be understood as an unavailable time-domain resource element.

[0138] In one possible implementation, the first communication device can actively detect signals from the same or different systems, such as Wi-Fi, SLP, or radar signals, in a first frequency band to determine interference information, and determine a third and / or fourth time-domain resource unit based on the interference information and at least two first time-domain resource units. For example, if the first communication device is as shown in Figure 3, the extended Wi-Fi module and other communication modules can actively detect signals in the first frequency band to determine interference information. The extended Wi-Fi module and other communication modules can send the determined interference information to the COEX module, which then determines the third and / or fourth time-domain resource units based on the interference information and at least two first time-domain resource units.

[0139] If the first communication device is a non-access point site device, then the second communication device can be an access point site device. The first communication device can send a first radio frame to the second communication device to indicate its third and / or fourth time-domain resource units, thereby allowing the second communication device to determine the time-domain resource unit from which the second signal is transmitted, such as the sixth time-domain resource unit. The sixth time-domain resource unit may be part or all of the third time-domain resource units. In one possible scenario, the second communication device can indicate the sixth time-domain resource unit to the first communication device, thereby allowing the first communication device to receive the second signal in the sixth time-domain resource unit. For example, the second communication device can broadcast resource unit allocation information, and the first communication device can receive the broadcast resource unit allocation information to determine that the resource unit allocated by the second communication device is the sixth time-domain resource unit. Optionally, the first radio frame may include a bitmap to indicate available and / or unavailable time-domain resource units, which will not be elaborated further here.

[0140] Optionally, the second communication device may also receive indications of available and / or unavailable time domain resource units from other associated non-access point site devices, as well as other indications of available and / or unavailable time domain resource units for associated non-access point site devices. In this way, the second communication device can reallocate time domain resource units for receiving or transmitting for different non-access point site devices. The aforementioned resource unit allocation information may include the reallocation of time domain resource units for receiving or transmitting for different non-access point site devices.

[0141] In one example, if the first communication device is an access point site device, then the second communication device can be a non-access point site device. The first communication device can send a first radio frame to the second communication device, indicating a third time-domain resource unit and / or a fourth time-domain resource unit, thereby allowing the second communication device to determine the time-domain resource unit for transmitting the second signal, such as a sixth time-domain resource unit. The sixth time-domain resource unit is some or all of the third time-domain resource units. The first communication device can receive the second signal on the sixth time-domain resource unit. Optionally, the second communication device can engage in channel contention to transmit the second signal on the sixth time-domain resource unit. In one possible scenario, the first radio frame may include a bitmap to indicate available and / or unavailable time-domain resource units, which will not be elaborated further here.

[0142] In another example, if the first communication device is an access point site device, then the first radio frame may include indication information for a third time-domain resource unit. In this scenario, the third time-domain resource unit can be understood as a time-domain resource unit allocated by the second communication device for transmitting the second signal. The second communication device can transmit the second signal on the third time-domain resource unit, and the first communication device can receive the second signal on the third time-domain resource unit.

[0143] Optionally, the first communication device may also receive indications of available and / or unavailable time-domain resource elements from other associated non-access point site devices, as well as other indications of available and / or unavailable time-domain resource elements for associated non-access point site devices. In this way, the first communication device can reallocate time-domain resource elements for receiving or transmitting for different non-access point site devices. The first radio frame may include the first communication device's reallocation of time-domain resource elements for receiving or transmitting for different non-access point site devices.

[0144] Based on the above scheme, the first communication device can time-division the first signal and the second signal to reduce mutual interference.

[0145] In some embodiments, the first signal may be a periodic signal or an aperiodic signal. If the first signal is an aperiodic signal, the first communication device may refer to the method shown in the embodiment of FIG4 to reduce the complexity of the first communication device.

[0146] Based on the concept of the above embodiments, and referring to FIG9, this application provides a communication device 900, which includes a processing unit 910 and a transceiver unit 920. The device 900 can be a communication device, or it can be an apparatus applied to a communication device that supports the communication device in performing communication methods.

[0147] The transceiver unit can also be referred to as a transceiver module, transceiver, transceiver machine, transceiver device, etc. The processing unit can also be referred to as a processor, processing board, processing unit, processing device, etc. Optionally, the device in the transceiver unit used to implement the receiving function can be considered as a receiving unit. It should be understood that the transceiver unit is used to execute the sending and receiving operations of the communication device in the above method embodiments, and the device in the transceiver unit used to implement the sending function can be considered as a sending unit; that is, the transceiver unit includes a receiving unit and a sending unit.

[0148] Furthermore, it should be noted that if the device is implemented using a chip / chip circuit, the transceiver unit can be an input / output circuit and / or a communication interface, performing input operations (corresponding to the aforementioned receiving operations) and output operations (corresponding to the aforementioned sending operations); the processing unit is an integrated processor, microprocessor, or integrated circuit.

[0149] In some possible implementations, the communication device 900 can correspondingly implement the behavior and functions of the first communication device, etc., in the above-described method embodiments. For example, the communication device 900 can be the first communication device, or it can be a component (e.g., a chip or circuit) applied in the first communication device. The transceiver unit 920 can be used to perform all the receiving or transmitting operations performed by the first communication device in the embodiments shown in FIG4 or FIG8. For example, S401 in the embodiment shown in FIG4, and / or other processes used to support the technology described herein; wherein, the processing unit 910 is used to perform all operations other than the receiving and transmitting operations performed by the first communication device in the embodiments shown in FIG4 or FIG8.

[0150] For example, processing unit 910 is configured to determine at least two first time-domain resource units, which are used to carry a first signal. The first signal is a signal of a first communication protocol, and the frequency domain resource carrying the first signal corresponds to a first frequency band. Transceiver unit 920 is configured to transmit a second signal on a second time-domain resource unit. When the interval between at least two first time-domain resource units is less than a first threshold, the frequency domain resource carrying the second signal corresponds to a second frequency band. Alternatively, when the interval between at least two first time-domain resource units is greater than or equal to the first threshold, the frequency domain resource carrying the second signal corresponds to a first frequency band, and the second time-domain resource unit does not overlap with the at least two first time-domain resource units. The second signal includes at least one signal that satisfies a Wi-Fi protocol.

[0151] For example, processing unit 910 is used to determine at least two first time-domain resource units, which are used to carry a first signal. The first signal is a signal of a first communication protocol, and the frequency-domain resource carrying the first signal corresponds to a first frequency band. Transceiver unit 920 is used to transmit a second signal on a second time-domain resource unit. The frequency-domain resource carrying the second signal corresponds to a second frequency band, and the second signal includes at least one signal that satisfies the Wi-Fi protocol.

[0152] For example, processing unit 910 is used to determine at least two first time-domain resource units, each first time-domain resource unit being used to carry a first signal. The first signal is a signal of a first communication protocol, and the frequency domain resource carrying the first signal corresponds to a first frequency band. Transceiver unit 920 is used to transmit a first wireless frame. The first wireless frame includes indication information for a second time-domain resource unit. Alternatively, the first wireless frame includes indication information for a third time-domain resource unit and / or an indication information for a fourth time-domain resource unit. The second time-domain resource unit is used to receive a second signal, and the frequency domain resource carrying the second signal corresponds to a second frequency band. The third time-domain resource unit is used to receive the second signal, and the frequency domain resource carrying the second signal corresponds to the first frequency band. The third time-domain resource unit does not overlap with at least two first time-domain resource units, and the fourth time-domain resource unit is the same as at least two first time-domain resource units. The second signal includes at least one signal satisfying the Wi-Fi protocol.

[0153] In other possible implementations, the communication device 900 can correspondingly implement the behavior and functions of the second communication device, etc., in the above method embodiments. For example, the communication device 900 can be the second communication device, or it can be a component (e.g., a chip or circuit) applied in the second communication device.
