Description

Communication method and communication apparatus

[0001] The present application claims priority to the Chinese patent application No. 202410545398.0, filed on April 30, 2024, and entitled "Communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and more particularly, to a communication method and a communication apparatus. BACKGROUND

[0003] With the increasing demand for wireless spectrum resources, a hybrid sharing method allowing wireless local area network (WLAN) and cellular network to work cooperatively in the same spectrum is being discussed. In this method, the coverage of the wireless local area network system and the coverage of the cellular network may overlap. If the frequency band used by the wireless local area network and the frequency band used by the cellular network overlap in this case, a co-channel interference problem will occur, resulting in poor received signal quality.

[0004] To solve the co-channel interference problem, the network device will send an interference coordination signal (ICS) in the coverage of the cellular network, and use the signal to instruct all wireless local area network access points in the coverage to prohibit the use of the frequency band used by the cellular network. However, this will cause all wireless local area network basic service sets that receive the ICS to be unable to use the frequency band, reducing the spectrum utilization efficiency. SUMMARY

[0005] The present application provides a communication method and a communication apparatus, which reports BSS identification information to a cellular network device through a first device, so that the cellular network device can accurately instruct the corresponding BSS to adjust the transmission strategy on the communication frequency band, and accurately adjust the frequency band transmission strategy in the interference source.

[0006] In a first aspect, a communication method is provided, which can be executed by a cellular network device. In the absence of special instructions, the "first communication apparatus" in the present application can refer to the cellular network device itself, or a component (such as a processor, a chip, or a chip system, etc.) in the cellular network device, or a logic module or software capable of realizing all or part of the functions of the cellular network device.

[0007] The method comprises: receiving, by the cellular network device, first information from a first device, the first information comprising identification information of a first basic service set (BSS), the first BSS being a BSS to which the first device belongs; determining, by the cellular network device, second information according to the first information, the second information comprising information of a first transmission strategy and identification information of the first BSS, the second information being used to instruct the first BSS to adjust a transmission strategy on a first frequency band to the first transmission strategy; and sending, by the cellular network device, the second information to an access point of a wireless local area network. Thus, the cellular network device can accurately instruct the interference source to adjust by receiving the identification information of the interference source, and can ensure that the cellular network system can continue to perform spectrum multiplexing with the wireless local area network system other than the interference source. The cellular network device can send the second information in a broadcast manner, or it can also be understood that the cellular network device sends the second information to one or more access points in the coverage of the cellular network.

[0008] With reference to the first aspect, in some implementations of the first aspect, the first information is used to indicate an interference situation of a signal in a wireless local area network on a signal in a cellular network, the wireless local area network being a network to which the first BSS belongs, the first frequency band being a frequency band used for communication by the first BSS, and the cellular network being a network used for communication between the first device and the cellular network device. The first information is specifically used to indicate that the signal in the wireless local area network to which the first BSS belongs causes interference to the signal in the cellular network, and the first BSS needs to adjust the transmission strategy when working on the first frequency band.

[0009] With reference to the first aspect, in some implementations of the first aspect, the first transmission strategy comprises at least one of the following: controlling the transmission power on the first frequency band to be less than a first threshold, prohibiting the use of the first frequency band to send a signal, puncturing a resource unit corresponding to the first frequency band, or switching the frequency band used by the first BSS to a second frequency band. Thus, the cellular network device sends the indication information to indicate the adjustment strategy of the first BSS through the cellular network, so that the signal in the wireless local area network to which the first BSS belongs no longer causes interference to the signal in the cellular network.

[0010] With reference to the first aspect, in some implementations of the first aspect, the first information further comprises at least one of the following: signal quality corresponding to the first frequency band, identification information of the first frequency band, or channel information corresponding to the first frequency band; and the identification information of the first BSS comprises a first BSS identifier or a first BSS color. Thus, after receiving the first information, the cellular network device can determine the frequency band adjustment strategy of the first BSS according to the first information. That is, the first information can be used to indicate characteristic information of the wireless local area network that causes interference to the cellular network, so that the cellular network device can determine the frequency band adjustment strategy of the first BSS according to the first information after receiving the first information.

[0011] In some implementations of the first aspect, the method further includes: determining a second transmission strategy of the interference coordination signal according to the first information; and sending, by the cellular network device, the second information to the access point of the wireless local area network includes: sending, by the cellular network device, the interference coordination signal to the access point of the wireless local area network according to the second transmission strategy, the interference coordination signal including the second information. Thus, it is further ensured that the access point belonging to the first BSS can receive the interference coordination signal, and it is avoided that the interference source does not receive the indication information of adjusting the frequency band transmission strategy after the second information is sent by using the broadcast mode.

[0012] In some implementations of the first aspect, the second transmission strategy includes at least one of the following: the sending power of the interference coordination signal is greater than a second threshold; the interference coordination signal is sent on a first beam, and the first beam satisfies at least one of the following conditions: the identifier of the first beam is the same as the identifier of a second beam, and the second beam is the beam carrying the first information; or the first beam is a beam used by the first device and the cellular network device for communication, or the direction of the first beam corresponds to the position of the first device. That is, it is ensured that the interference source receives the indication information of adjusting the frequency band transmission strategy by increasing the sending power and / or the sending direction of the interference coordination signal.

[0013] In a second aspect, a communication method is provided, which can be performed by a first device. In the absence of special description, the "first communication device" in the present application can refer to the first device itself, a component (for example, a processor, a chip, or a chip system, etc.) in the first device, or a logic module or software capable of realizing all or part of the functions of the first device.

[0014] The method includes: sending, by the first device, first information to a cellular network device, the first information including identifier information of a first BSS, the first BSS being a BSS to which the first device belongs. Thus, the first device first determines that the signal in the wireless local area network causes interference to the signal in the cellular network, and reports the identifier information of the interference source to the cellular network device, so that the cellular network device can subsequently accurately instruct the interference source to adjust, and ensure that the cellular network system can continue to perform spectrum multiplexing with the wireless local area network system other than the interference source.

Specifically, the first information is used to indicate that the signal in the wireless local area network to which the first BSS belongs causes interference to the signal in the cellular network, and the first BSS needs to adjust the transmission strategy when working in the first frequency band.

[0016] With reference to the second aspect, in some implementations of the second aspect, the first information further comprises at least one of: signal quality corresponding to the first frequency band, identification information of the first frequency band, or channel information corresponding to the first frequency band; and the identification information of the first BSS comprises a first BSS identification or a first BSS color. Thus, after receiving the first information, the cellular network device can determine the frequency band adjustment strategy of the first BSS according to the first information. That is, the first information can be used to indicate characteristic information of the wireless local area network that causes interference to the cellular network, so that after receiving the first information, the cellular network device can determine the frequency band adjustment strategy of the first BSS according to the first information.

[0017] The third aspect provides a communication method, which can be performed by an access point of a wireless local area network. In the present application, “the first communication device” can refer to the access point of the wireless local area network itself, a component (for example, a processor, a chip, or a chip system) in the access point of the wireless local area network, or a logic module or software that can realize all or part of the function of the access point device of the wireless local area network.

[0018] The method comprises: receiving, by the access point of the wireless local area network, second information from a cellular network device, the second information comprising information of a first transmission strategy and identification information of a first BSS, the second information being used to indicate that the transmission strategy of the first BSS on a first frequency band is adjusted to the first transmission strategy; and when the access point belongs to the first BSS, adjusting, by the access point, the transmission strategy on the first frequency band to the first transmission strategy. Thus, the first device first determines that the signal in the wireless local area network causes interference to the signal in the cellular network, and reports the identification information of the interference source to the cellular network device, so that the cellular network device can subsequently accurately instruct the interference source to adjust, and ensure that the cellular network system can continue to perform spectrum multiplexing with the wireless local area network system other than the interference source. The “access point belongs to the first BSS” can be replaced by “the access point provides the first BSS”, and the “first BSS is one of one or more BSSs provided by the access point”.

Thus, the cellular network device sends the indication information to indicate the adjustment strategy of the first BSS, so that the signals in the wireless local area network to which the first BSS belongs no longer interfere with the signals in the cellular network.

[0021] In some implementations of the third aspect, the access point further sends third information, where the third information is used to notify the second device that the transmission strategy of the access point on the first frequency band is adjusted to the first transmission strategy. Thus, the devices belonging to the first BSS can communicate with each other using the wireless local area network after the adjustment of the transmission strategy.

[0022] In some implementations of the third aspect, the access point further sends fourth information, where the fourth information is used to instruct the second device to adjust the transmission strategy on the first frequency band to the first transmission strategy. Thus, when the interference is caused to the non-AP devices in the first BSS, the interference of the wireless local area network to the cellular network is solved.

[0023] In the fourth aspect, a communication device for use in a cellular network is provided, which comprises: a transceiver module configured to receive first information from a first device, where the first information comprises identification information of a first BSS, and the first BSS is a BSS to which the first device belongs; a processing module configured to determine second information according to the first information, where the second information comprises information of a first transmission strategy and identification information of the first BSS, and the second information is used to instruct the first BSS to adjust the transmission strategy on a first frequency band to the first transmission strategy; and the transceiver module is further configured to send the second information to an access point of a wireless local area network. Thus, the device can accurately instruct the interference source to adjust by receiving the identification information of the interference source, and ensure that the cellular network system can continue to perform spectrum multiplexing with the wireless local area network system other than the interference source.

Thus, the cellular network device transmits the indication information to the first BSS to indicate the adjustment strategy, so that the signals in the wireless local area network to which the first BSS belongs no longer interfere with the signals in the cellular network.

[0061] The technical solutions in the present application will be described below with reference to the drawings.

[0062] The technical solutions provided by the embodiments of the present application can be applied to various cellular network systems and wireless local area network systems.

[0065] The above communication system applicable to the present application is only an example, and the communication system applicable to the present application is not limited thereto. Herein, the following will not be repeated.

[0066] FIG. 1 is a schematic diagram of an application scenario applicable to an embodiment of the present application. As shown in FIG. 1, the communication method provided by the present application is applicable to a scenario including a cellular network system and a wireless local area network system. In the application scenario, a cellular network device 100, an access point of a wireless local area network, a first device 200 and a second device 311 can be provided.

[0067] In the embodiments provided by the present application, the cellular network device 100 can be an evolutional node B (eNB or eNodeB) in an LTE system, and can also be a radio controller in a cloud radio access network (CRAN) scenario, or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a 5G network or a network device in a public land mobile network (PLMN), etc., and the embodiments of the present application are not limited thereto.

[0068] The access point of the wireless local area network can be a device supporting Wi-Fi mode. For example, the access point can also support one or more standards of IEEE 802.11 series such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11bn / UHR, 802.11ad, 802.11ay, etc. The access point device is mainly deployed in a home, an indoor building and an indoor park, and a typical coverage radius is tens of meters to hundreds of meters, and of course, the access point can also be deployed outdoors. The access point is equivalent to a bridge connecting a wired network and a wireless network, and mainly functions to connect various wireless network clients together and then access the wireless network to an Ethernet. Specifically, the access point can also be a terminal or a network device with a WiFi chip, and the access point device can be a server, a router, a switch, a bridge, a computer, a mobile phone, a relay station, a vehicle-mounted device, a wearable device, a network device in a 5G network or a network device in a PLMN, etc., and the embodiments of the present application are not limited thereto.

[0069] The first device 200 can be a device that supports both cellular network and wireless local area network. The first device 200 can be an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user device, a user terminal, a terminal, a wireless communication device, a user agent, or a user equipment. The terminal can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a 5G network, or a terminal in a PLMN, etc. The embodiments of the present application are not limited thereto.

[0070] The second device 311 can be a station, which can be a mobile phone, a tablet computer, a set-top box, a smart television, a smart wearable device, an in-vehicle communication device, a computer, an internet of things (IoT) node, a sensor, a smart home device such as a smart camera, a smart remote controller, a smart water meter, and a sensor in a smart city, etc. In addition, the second device 311 can also be a device that supports both cellular network and wireless local area network, which is similar to the first device 200, and will not be described here.

[0071] In addition, those skilled in the art can easily understand that the above-mentioned cellular network device, access point, station, first device, and second device can also be replaced by other names according to actual conditions.

[0072] As shown in FIG. 1, the cellular network device 100 is configured to provide a cellular network. The first access point 310 provides a first basic service set (BSS), and the second access point 320 provides a second BSS. The first BSS and the second BSS are wireless local area network BSSs. A station accessing the first BSS or the second BSS, such as the second device 311 belonging to the first BSS, can communicate with the access point using a wireless local area network.

[0073] The first device 200 is located in an overlapping area of a cellular network and a wireless local area network provided by the first access point 310. The first device 200 can communicate with the cellular network device 100 using the cellular network or communicate with the first access point 310 using the wireless local area network. If the frequency band used by the wireless local area network overlaps the frequency band used by the cellular network, a co-channel interference problem occurs, resulting in poor signal quality. To solve the co-channel interference problem, the cellular network device 100 broadcasts ICS to all access points in the coverage range to prohibit the use of the frequency band used by the cellular network. However, this causes all wireless local area network BSSs that receive the ICS to be unable to use the frequency band, such as the first BSS and the second BSS in FIG. 1. However, at this time, there is no co-channel interference problem in the range of the second BSS, which reduces the spectrum utilization efficiency.

[0074] In view of this, the embodiments of the present application provide a communication method and a communication apparatus. The first device reports BSS identification information to the cellular network device, so that the cellular network device can accurately instruct the corresponding BSS to adjust the transmission strategy on the communication frequency band and accurately adjust the frequency band transmission strategy of the interference source.

[0075] FIG. 2 is a schematic diagram of a communication method provided by an embodiment of the present application. As shown in FIG. 2, the method includes steps S210-S240.

[0076] S210, the first device sends first information to the cellular network device, the first information including identification information of the first BSS, the first BSS being a BSS to which the first device belongs. Correspondingly, the cellular network device receives the first information from the first device.

[0077] The first information can be used to indicate the interference of signals in the wireless local area network on signals in the cellular network. The wireless local area network is the network to which the first BSS belongs, and the cellular network is the network used by the first device to communicate with the cellular network device. The first BSS uses a first frequency band for communication. The first information specifically indicates that signals in the wireless local area network to which the first BSS belongs interfere with signals in the cellular network. When operating in the first frequency band, the first BSS needs to adjust the transmission strategy.

[0078] The first device can detect the WLAN signal before sending the first information to the cellular network device, or can also be understood as the first device listens to the WLAN signal. That is, the first device can determine that the signal in the WLAN causes interference to the signal in the cellular network by detecting the WLAN signal, and send the first information to the cellular network device after determining that the interference problem occurs. For example, the first device can determine that the signal in the WLAN causes interference to the signal in the cellular network when the first device communicates with the cellular network device through the cellular network, by determining that the WLAN signal quality is greater than a preset threshold. In some implementations, the first device determines that the WLAN causes interference to the cellular network by determining that the frequency band used for the cellular network communication overlaps with the first frequency band used for the WLAN communication. The WLAN signal detected by the first device can be a broadcast signal, such as a beacon frame, a probe request frame, etc., which is determined according to actual conditions. The signal quality detected by the first device can be signal strength, signal energy, signal amplitude, signal power, signal interference strength, signal interference threshold, or signal-to-noise ratio, etc., which is determined according to actual conditions.

[0079] In some implementations, the first information can only include the first BSS identification information, that is, the first device can only indicate that the signal in the WLAN to which the first BSS belongs causes interference to the signal in the cellular network by indicating the first BSS information. The identification information of the first BSS can be a first BSS identification (ID) or a first BSS color.

[0080] In some implementations, the first information further includes at least one of the following: signal quality corresponding to the first frequency band, identification information of the first frequency band, or channel information corresponding to the first frequency band. That is, the first information can be used to indicate the characteristic information of the WLAN that causes interference to the cellular network, so that the cellular network device can determine the frequency band adjustment strategy of the first BSS according to the first information after receiving the first information.

[0081] The signal quality corresponding to the first frequency band can be signal strength, signal energy, signal amplitude, signal power, signal interference strength, signal interference threshold, or signal-to-noise ratio, etc.

[0082] The identification information of the first frequency band can include a frequency band number, a channel number, etc. When the identification information of the first frequency band is a channel number, the channel number can specifically refer to a channel number of a cellular network and / or a channel number of a wireless local area network. Alternatively, the identification information of the first frequency band can be determined by, for example, channel identification information, frequency band identification information, bandwidth information, resource block information, resource unit information, etc. In addition, the "frequency band" can be replaced by "frequency range", "frequency resource", etc. according to actual conditions. The channel information corresponding to the first frequency band can refer to part or all of the channels used by the first BSS communication, which at least includes the channel corresponding to the first frequency band. Alternatively, the channel information corresponding to the first frequency band can also refer to the channel puncturing information corresponding to the first frequency band. The channel puncturing information can be obtained by the first device through receiving a broadcast frame sent by an access point of a wireless local area network. The broadcast frame can be a management frame, a request frame, a notification frame, etc. The broadcast frame includes preamble puncture information.

[0083] In S220, the cellular network device determines second information according to the first information. The second information includes information of the first transmission strategy and identification information of the first BSS. The second information is used to indicate that the transmission strategy of the first BSS on the first frequency band is adjusted to the first transmission strategy.

[0084] The first transmission strategy can be determined by the cellular network device according to the first information and directly indicated by the cellular network device. Alternatively, the first transmission strategy is determined by the access point of the wireless local area network according to the second information after receiving the second information, or the first transmission strategy is further adjusted and determined by the access point of the wireless local area network according to the communication condition after receiving the second information.

[0085] In some implementations, the first transmission strategy includes at least one of the following: controlling the transmission power on the first frequency band to be less than a first threshold, prohibiting the use of the first frequency band to send signals, puncturing the resource unit corresponding to the first frequency band, or switching the frequency band used by the first BSS to a second frequency band. The prohibition of using the first frequency band to send signals can specifically refer to the prohibition of using the first frequency band to send signals in the first time period. Thus, the cellular network device sends the indication information to indicate the adjustment strategy of the first BSS through the cellular network, so that the signals in the wireless local area network to which the first BSS belongs no longer interfere with the signals in the cellular network.

[0086] When the identification information of the first frequency band is a channel number of the cellular network, the cellular network device can translate the channel number of the cellular network into a channel number of the wireless local area network after receiving the first information, and the second information includes the channel number of the wireless local area network. Alternatively, the cellular network device does not translate the channel number of the cellular network after receiving the first information, and the second information includes the channel number of the cellular network. The access point of the wireless local area network translates the channel number of the cellular network to obtain the channel number of the wireless local area network after receiving the second information.

[0087] In addition, the "first transmission strategy" can be replaced by "first transmission processing", "first transmission configuration" and the like, and the present application does not make any limitation in this regard.

[0088] S230, the cellular network device sends second information to the access point of the wireless local area network. Correspondingly, the access point receives the second information from the cellular network device.

[0089] The cellular network device can send the second information in a broadcast manner, or it can also be understood that the cellular network device sends the second information to one or more access points within the coverage of the cellular network.

[0090] In some implementations, the communication method as shown in FIG. 2 further includes determining a second transmission strategy of the interference coordination signal according to the first information. The cellular network device sending the second information to the access point of the wireless local area network includes: the cellular network device sending the interference coordination signal to the access point of the wireless local area network according to the second transmission strategy, and the interference coordination signal includes the second information. Thus, it is further ensured that the access point belonging to the first BSS can receive the interference coordination signal, and it is avoided that the interference source does not receive the indication information of adjusting the frequency band transmission strategy after sending the second information in a broadcast manner.

[0091] The second transmission strategy includes at least one of the following: the sending power of the interference coordination signal is greater than a second threshold; and the interference coordination signal is sent on a first beam. The first beam satisfies at least one of the following conditions: the identification of the first beam is the same as the identification of a second beam, and the second beam is the beam carrying the first information; or the first beam is a beam used for communication between the first device and the cellular network device, or the direction of the first beam corresponds to the position of the first device. That is, the indication information of adjusting the frequency band transmission strategy is ensured to be received by the interference source by increasing the sending power and / or the sending direction of the interference coordination signal.

[0092] S240, when the access point belongs to the first BSS, the access point adjusts the transmission strategy on the first frequency band to the first transmission strategy.

[0093] When the access point does not belong to the first BSS, the access point does not adjust the transmission strategy. In addition, "the access point belongs to the first BSS" can be replaced by "the access point provides the first BSS", and "the first BSS is one of one or more BSSs provided by the access point".

[0094] The first transmission strategy can be directly indicated by the cellular network device. Alternatively, the first transmission strategy is determined by the access point according to the second information after receiving the second information, or the first transmission strategy is further determined by the access point of the wireless local area network according to the communication condition after receiving the second information. The first transmission strategy has been described in step S220 and will not be repeated here.

[0095] In some implementations, the access point sends third information, and the third information is used to inform the second device that the transmission strategy of the access point on the first frequency band is adjusted to the first transmission strategy. The access point and the second device use wireless local area network communication. Thus, it is ensured that the devices belonging to the first BSS can use the wireless local area network communication after adjusting the frequency band transmission strategy.

[0096] In some implementations, the access point sends fourth information, and the fourth information is used to instruct the second device to adjust the transmission strategy on the first frequency band to the first transmission strategy. The access point and the second device use wireless local area network communication. Thus, when the interference is caused to the non-AP device in the first BSS, the interference problem caused by the wireless local area network to the cellular network is solved. In some implementations, the fourth information includes fifth information, and the fifth information is used to instruct the second device to puncture the resource unit corresponding to the first frequency band. The fifth information is determined by the access point according to the second information.

[0097] In the method as shown in FIG. 1, the first device first reports the identification information of the interference source to the cellular network device, so that the cellular network device can accurately instruct the interference source to adjust, and ensure that the cellular network system can continue to perform spectrum multiplexing with the wireless local area network system other than the interference source.

[0098] Next, the specific implementation of the communication method will be described in combination with FIGS. 3 to 5.

[0099] FIG. 3 is a schematic diagram of another communication method provided by an embodiment of the present application. As shown in FIG. 3, the method includes steps S310-S340.

[0100] S310, the first device sends first information to the cellular network device, and the first information includes identification information of the first BSS and signal quality corresponding to the first frequency band. The first BSS is a BSS to which the first device belongs. Correspondingly, the cellular network device receives the first information from the first device. For example, the first information indicates that the signal energy on the first frequency band is -75 dBm, and the signal interference threshold on the first frequency band is -85 dBm.

[0101] S320, the cellular network device determines second information according to the first information, the second information comprising information of the first transmission strategy and identification information of the first BSS, and the second information being used to instruct the first BSS to adjust the transmission strategy on the first frequency band to the first transmission strategy.

[0102] The cellular network device determines, according to the first information, that the signal power level on the first frequency band is 10 dB, and the cellular network device sends the second information to instruct the access point of the wireless local area network to reduce the signal power level on the first frequency band by 10 dB.

[0103] S330, the cellular network device sends the second information to the access point of the wireless local area network. Correspondingly, the access point receives the second information from the cellular network device.

[0104] S340, when the access point belongs to the first BSS, the access point adjusts the transmission strategy on the first frequency band to the first transmission strategy.

[0105] If the signal quality on the first frequency band meets the communication requirement after the power is reduced, the access point reduces the signal power on the first frequency band according to the instruction of the second information. If the signal quality on the first frequency band does not meet the communication requirement after the power is reduced, the access point switches the frequency band used by the first BSS to the second frequency band. And the access point sends third information to notify that the access point switches the frequency band used by the first BSS to the second frequency band.

[0106] Therefore, the cellular network device can accurately instruct the interference source to adjust according to the interference source characteristics reported by the first device.

[0107] FIG. 4 is a schematic diagram of another communication method provided by an embodiment of the present application. As shown in FIG. 4, the method comprises steps S410-S450.

[0108] S410, a first device sends first information to a cellular network device, the first information comprising identification information of a first BSS, signal quality corresponding to a first frequency band, and the first BSS being a BSS to which the first device belongs. Correspondingly, the cellular network device receives the first information from the first device. For example, the first information instructs that the signal receiving power on the first frequency band is -70 dBm.

[0109] S420, the cellular network device determines second information according to the first information, the second information comprising information of the first transmission strategy and identification information of the first BSS, and the second information being used to instruct the first BSS to adjust the transmission strategy on the first frequency band to the first transmission strategy.

[0110] S430, the cellular network device determines a second transmission strategy of the interference coordination signal according to the first information.

[0111] Since the first frequency band used by the wireless local area network overlaps the third frequency band used by the cellular network, the cellular network device judges that the signal receiving power on the third frequency band is-70dBm, and the access point is located indoors, and there is a loss of 10dB between indoors and outdoors. The cellular network device increases the transmission power of the interference coordination signal by 10dB.

[0112] The cellular network device determines to use the first beam to transmit the interference coordination signal. The identity of the first beam is the same as the identity of the second beam, and the second beam is the beam used by the first device to transmit the first information.

[0113] S440, the cellular network device sends an interference coordination signal to the access point of the wireless local area network, and the interference coordination signal includes the second information. Correspondingly, the access point receives the second information from the cellular network device.

[0114] S450, when the access point belongs to the first BSS, the access point adjusts the transmission strategy on the first frequency band to the first transmission strategy.

[0115] Therefore, the cellular network device ensures that the interference source receives the indication information of adjusting the frequency band transmission strategy by increasing the transmission power and the transmission direction of the interference coordination signal. And ensure that the interference source first BSS can adjust the frequency band transmission strategy according to the cellular network device.

[0116] Fig. 5 is a schematic diagram of another communication method provided by an embodiment of the present application. As shown in Fig. 5, the method comprises steps S510-S540.

[0117] S510, the first device sends first information to the cellular network device, and the first information includes the identity information of the first BSS, which is the BSS to which the first device belongs. Correspondingly, the cellular network device receives the first information from the first device.

[0118] Wherein, before sending the first information, the first device determines that the signal in the wireless local area network causes interference to the signal in the cellular network, and the wireless local area network uses the first frequency band for communication. And the first device obtains the preamble puncturing information from the broadcast frame sent by the access point of the wireless local area network. If the access point punctures the corresponding channel of the first frequency band on the next communication window, the first information sent by the first device does not include the channel information corresponding to the first frequency band. If the access point does not puncture the corresponding channel of the first frequency band on the next communication window, the first information sent by the first device includes the channel information corresponding to the first frequency band.

[0119] S520, the cellular network device determines second information according to the first information, the second information comprising information of the first transmission strategy and identification information of the first BSS, and the second information being used to instruct the first BSS to adjust the transmission strategy on the first frequency band to the first transmission strategy. Wherein, when the first information comprises channel information corresponding to the first frequency band, the first transmission strategy determined by the cellular network device can comprise puncturing resource units corresponding to the first frequency band.

[0120] S530, the cellular network device sends the second information to an access point of the wireless local area network. Correspondingly, the access point receives the second information from the cellular network device.

[0121] S540, when the access point belongs to the first BSS, the access point adjusts the transmission strategy on the first frequency band to the first transmission strategy.

[0122] Therefore, the cellular network device can instruct the access point to perform channel puncturing according to the channel information reported by the first device, so that signals in the wireless local area network to which the first BSS belongs no longer interfere with signals in the cellular network.

[0123] It should be understood that the combination of each of the above embodiments is only an example, and does not constitute any limitation on the protection scope of the present application, and new embodiments can also be combined, which are not exemplified here.

[0124] It should be understood that each of the above method embodiments is a method and operation realized by a device (such as a cellular network device, a first device, an access point, a second device), which can also be realized by a component (such as a chip or a circuit) of the device.

[0126] Figure 6 is a schematic structural block diagram of a communication apparatus provided in the embodiments. The communication apparatus 600 can include a transceiver module 610 and a processing module 620. The communication apparatus 600 shown in Figure 6 can be a first communication apparatus, which can be a cellular network device or a component (e.g., a chip or a circuit) in the cellular network device in the above-described embodiments. Alternatively, the communication apparatus 600 shown in Figure 6 can be a second communication apparatus, which can be the first device or a component (e.g., a chip or a circuit) in the first device in the above-described embodiments.

[0127] In the following, the apparatus shown in Figure 6 is described in combination with the specific communication apparatus being the above-described three apparatuses.

[0128] The first communication apparatus

[0129] The transceiver module 610 is configured to receive first information from the first device, and the first information includes identification information of a first BSS, the first BSS being a BSS to which the first device belongs.

[0130] In some embodiments, the first information can be used to indicate the interference of signals in the wireless local area network to signals in the cellular network. The wireless local area network is a network to which the first BSS belongs, and the cellular network is a network used by the first device to communicate with the cellular network device. In some embodiments, the first BSS communicates using a first frequency band. In some embodiments, the first information is specifically used to indicate that the signals in the wireless local area network to which the first BSS belongs interfere with the signals in the cellular network, and the first BSS needs to adjust the transmission strategy when working in the first frequency band.

[0131] In some embodiments, the first information can only include the first BSS identification information, i.e., the first device can only indicate that the signals in the wireless local area network to which the first BSS belongs interfere with the signals in the cellular network by indicating the first BSS information. The identification information of the first BSS can be a first BSS identification (ID) or a first BSS color (color).

[0132] In some embodiments, the first information further includes at least one of the following: signal quality corresponding to the first frequency band, identification information of the first frequency band, or channel information corresponding to the first frequency band. That is, the first information can be used to indicate the characteristic information of the wireless local area network that interferes with the cellular network, so that the cellular network device can determine the frequency band adjustment strategy of the first BSS according to the first information after receiving the first information.

[0133] The processing module 620 is configured to determine the second information according to the first information, the second information including information of the first transmission strategy and identification information of the first BSS, and the second information being used to indicate that the first BSS adjusts the transmission strategy on the first frequency band to the first transmission strategy.

[0134] In some implementations, the first transmission strategy includes at least one of the following: controlling the transmission power on the first frequency band to be less than a first threshold, prohibiting the use of the first frequency band to send signals, puncturing resource units corresponding to the first frequency band, or switching the frequency band used by the first BSS to a second frequency band. The prohibition of the use of the first frequency band to send signals can specifically refer to the prohibition of the use of the first frequency band to send signals on the first time period. Thus, the cellular network device sends the indication information to indicate the adjustment strategy of the first BSS through the cellular network, so that the signals in the wireless local area network to which the first BSS belongs no longer interfere with the signals in the cellular network.

[0135] When the identification information of the first frequency band is a channel number of the cellular network, the cellular network device can translate the channel number of the cellular network into a channel number of the wireless local area network after receiving the first information, and the second information includes the channel number of the wireless local area network. Alternatively, the cellular network device does not translate the channel number of the cellular network after receiving the first information, and the second information includes the channel number of the cellular network. The access point of the wireless local area network translates the channel number of the cellular network to obtain the channel number of the wireless local area network after receiving the second information.

[0136] The transceiver module 610 is further configured to send the second information to the access point of the wireless local area network.

[0137] The transceiver module 610 can send the second information in a broadcast manner, or it can be understood that the transceiver module 610 sends the second information to one or more access points within the coverage of the cellular network.

[0138] In some implementations, the processing module 620 is further configured to determine a second transmission strategy of the interference coordination signal according to the first information. The transceiver module 610 sending the second information to the access point of the wireless local area network includes that the transceiver module 610 sends the interference coordination signal to the access point of the wireless local area network according to the second transmission strategy, and the interference coordination signal includes the second information. Thus, it is further ensured that the access point belonging to the first BSS can receive the interference coordination signal, and the indication information of the adjustment of the frequency band transmission strategy is not received by the interference source after the second information is sent in a broadcast manner.

[0139] The second transmission strategy includes at least one of the following: the sending power of the interference coordination signal is greater than a second threshold; and the interference coordination signal is sent on a first beam. The first beam satisfies at least one of the following conditions: the identity of the first beam is the same as the identity of the second beam, and the second beam is the beam carrying the first information; or the first beam is a beam used by the first device for communication with the cellular network device, or the direction of the first beam corresponds to the position of the first device. That is, the indication information of the adjustment frequency band transmission strategy is ensured to be received by the interference source by increasing the sending power and / or the sending direction of the interference coordination signal.

[0140] In the first communication device, the device can accurately instruct the interference source to adjust by receiving the identification information of the interference source, and ensure that the cellular network system can continue to perform spectrum multiplexing with the wireless local area network system other than the interference source.

[0141] The second communication device

[0142] The transceiver module 610 is configured to send first information to the cellular network device, and the first information includes identification information of a first BSS. The first BSS is a BSS to which the first device belongs.

[0143] The transceiver module 610 can include a cellular module 611 and a wireless local area network module 612. The cellular transceiver module 611 is configured to perform cellular network communication. The wireless local area network module 612 is configured to perform wireless local area network communication. Before the transceiver module 610 sends the first information to the cellular network device, the processing module 620 can detect the wireless local area network signal, or it can also be understood that the processing module 620 listens to the wireless local area network signal. The processing module 620 can determine that the signal in the wireless local area network causes interference to the signal in the cellular network by detecting the wireless local area network signal. After determining that there is interference, the processing module 620 sends the first information to the cellular network device. For example, when the transceiver module 610 communicates with the cellular network device through the cellular network, the processing module 620 can determine that the signal in the wireless local area network causes interference to the signal in the cellular network when it is determined that the wireless local area network signal quality is greater than a preset threshold. In some implementations, the processing module 620 determines that the wireless local area network causes interference to the cellular network by determining that the frequency band used for cellular network communication overlaps with the first frequency band used for wireless local area network communication. The wireless local area network signal detected by the processing module 620 can be a broadcast signal, such as a beacon frame, a probe request frame, etc., which is determined according to actual conditions. The signal quality detected by the processing module 620 can specifically refer to signal strength, signal energy, signal amplitude, signal power, signal interference strength, signal interference threshold, or signal-to-noise ratio, etc., which is determined according to actual conditions.

[0144] In some embodiments, the first information can only include the first BSS identification information, i.e., the first device can only indicate that the signal in the wireless local area network to which the first BSS belongs causes interference to the signal in the cellular network by indicating the first BSS information. The identification information of the first BSS can be the first BSS identification (ID) or the first BSS color.

[0145] In some embodiments, the first information further includes at least one of the following: signal quality corresponding to the first frequency band, identification information of the first frequency band, or channel information corresponding to the first frequency band. That is, the first information can be used to indicate the characteristic information of the wireless local area network causing interference to the cellular network, so that the cellular network device can determine the frequency band adjustment strategy of the first BSS according to the first information after receiving the first information.

[0146] The identification information of the first frequency band can include a frequency band number, a channel number, etc. Or the identification information of the first frequency band can be determined by, for example, channel identification information, frequency band identification information, bandwidth information, resource block information, resource unit information, etc. In addition, "frequency band" can also be replaced by "frequency range", "frequency resource", etc. according to actual conditions.

[0147] The channel information corresponding to the first frequency band can refer to part or all of the channels used for communication by the first BSS, which at least includes the channel corresponding to the first frequency band. Or the channel information corresponding to the first frequency band can also refer to the channel puncture information corresponding to the first frequency band. The channel puncture information can be obtained by the transceiver 610 through receiving the broadcast frame sent by the access point of the wireless local area network. The broadcast frame can be a management frame, a request frame, a notification frame, etc., and the broadcast frame includes preamble puncture information.

[0148] In the second communication device, the device first determines that the signal in the wireless local area network causes interference to the signal in the cellular network, and reports the identification information of the interference source to the cellular network device, so that the cellular network device can subsequently accurately instruct the interference source to adjust, and ensure that the cellular network system can continue to perform spectrum multiplexing with the wireless local area network system other than the interference source.

[0149] The third communication device

[0150] The transceiver 610 is configured to receive second information from the cellular network device, the second information including information of a first transmission strategy and identification information of the first BSS, and the second information being used to indicate that the transmission strategy of the first BSS on the first frequency band is adjusted to the first transmission strategy.

[0151] The processing module 620 is configured to adjust the transmission strategy on the first frequency band to the first transmission strategy when the communication device belongs to the first BSS.

[0152] In some embodiments, the first transmission strategy comprises at least one of: controlling the transmission power on the first frequency band to be less than a first threshold, disabling the use of the first frequency band for signal transmission, puncturing resource units corresponding to the first frequency band, or switching the frequency band used by the first BSS to a second frequency band. The disabling of the use of the first frequency band for signal transmission can specifically refer to disabling the use of the first frequency band for signal transmission in the first time period. Thus, the cellular network device transmits the indication information indicating the adjustment strategy of the first BSS through the cellular network, so that the signals in the wireless local area network to which the first BSS belongs no longer interfere with the signals in the cellular network.

[0153] In some embodiments, the transceiver 610 is further configured to transmit third information, the third information being used to notify a second device that the transmission strategy of the access point on the first frequency band is adjusted to the first transmission strategy. The access point and the second device communicate using a wireless local area network. Thus, it is ensured that the devices belonging to the first BSS can communicate using the wireless local area network after the adjustment of the frequency band transmission strategy.

[0154] In some embodiments, the transceiver 610 is further configured to transmit fourth information, the fourth information being used to instruct the second device to adjust the transmission strategy on the first frequency band to the first transmission strategy. The access point and the second device communicate using a wireless local area network. Thus, when the interference is caused to the non-AP devices within the first BSS, the interference problem caused by the wireless local area network to the cellular network is solved. In some embodiments, the fourth information comprises fifth information, the fifth information being used to instruct the second device to puncture the resource units corresponding to the first frequency band. The fifth information is determined by the access point according to the second information.

[0155] In the third communication device, the device determines that it belongs to the first BSS causing the interference, and then adjusts the transmission strategy on the frequency band. Thus, the cellular network device can subsequently accurately instruct the interference source to adjust, and it is ensured that the cellular network system can continue to perform spectrum multiplexing with the wireless local area network system other than the interference source.

[0156] It should be understood that the communication device shown in FIG. 6 is embodied in the form of functional units. The term "unit" herein can refer to an application specific integrated circuit (ASIC), an electronic circuit, a processor (such as a shared processor, a dedicated processor, or a group processor, etc.) and a memory for executing one or more software or firmware programs, a combination of logic circuit and / or other suitable components supporting the described functions.

[0157] The communication apparatus shown in FIG. 6 implements the functions of the corresponding steps performed by the apparatus in the above method. The functions can be implemented by hardware or by executing corresponding software by hardware.
