Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of wireless communications, and in particular to a method and apparatus for receiving configuration information. Background Art
[0002] In a communication system, when a terminal or a relay station (hereinafter referred to as the terminal) receives a signal, the interference signal generated by the surrounding terminals, relay stations or wireless-fidelity (WiFi) devices is sometimes tens of dB stronger than the signal strength received by the terminal, which will affect the terminal's reception of the signal. In order to reduce the impact of the interference signal on the signal to be received by the terminal, the terminal needs to measure the interference signal to obtain the direction of arrival (DOA) of the interference signal, and process the original receiving beam according to the DOA of the interference signal and the DOA of the received signal to form a null-notched beam, and receive the signal through the null-notched beam. Because the null-notched beam has a main lobe and a null point, the receiving beam gain of the null point is 30-50dB lower than the receiving beam gain of the main lobe. Therefore, if the terminal aligns the null point with the direction of the interference signal and the main lobe with the direction of the signal to be received when receiving the signal, the interference signal can be suppressed and the signal can be received better. For example, after the original receiving beam of the terminal is processed by the DOA of the interference signal and the DOA of the received signal, the null-notched beam formed can be as follows Figure 1A shown.
[0003] Currently, before a terminal measures interference signals, the access point must collect statistics on the downlink channel quality or downlink data packet loss rate over a period of time and, based on the statistics, determine whether the terminal needs to measure interference signals. After the access point determines that the terminal needs to measure interference signals, it sends the terminal the relevant configuration for measuring interference signals. The terminal then receives the configuration and measures the interference signals accordingly. This process is slow, and triggering the terminal to measure interference signals takes a long time. Summary of the Invention
[0004] The embodiments of the present application provide a method and apparatus for receiving configuration information, which can shorten the time it takes to trigger a terminal to measure an interference signal.
[0005] To achieve the above objectives, the present invention adopts the following technical solutions:
[0006] In a first aspect, an embodiment of the present application provides a method for receiving configuration information, including: a terminal sends a request message to an access point for requesting measurement of an interference signal; the terminal receives first configuration information from the access point, where the first configuration information is used to indicate the length of time the terminal measures the interference signal.
[0007] In the method of the first aspect described above, the terminal may send a request message to the access point requesting interference signal measurement and receive first configuration information from the access point. The terminal may then measure the interference signal based on the first configuration information. In this process, the terminal initiates the interference measurement request. The terminal may directly measure the downlink channel and initiate an interference measurement request when the downlink channel quality is poor. Compared to the access point performing downlink channel quality statistics, the terminal can perceive changes in the downlink channel more promptly, thereby shortening the time it takes to trigger the terminal to measure the interference signal.
[0008] In conjunction with the first aspect, in a first possible implementation, the terminal measures the interference signal according to the first configuration information. Based on the above method, the terminal can measure the interference signal according to the first configuration information configured by the access point, and form a null-notched beam based on the measurement result to reduce the impact of the interference signal on the signal to be received by the terminal.
[0009] In combination with the first aspect and the first possible implementation manner of the first aspect, in a second possible implementation manner, the first configuration information includes a first time length for the terminal to measure the interference signal; or, the first configuration information includes a measurement period, and a second time length for the terminal to measure the interference signal within the measurement period; or, the first configuration information includes the first time length for the terminal to measure the interference signal and a bandwidth for the terminal to measure the interference signal; or, the first configuration information includes a measurement period, the second time length for the terminal to measure the interference signal within the measurement period, and the bandwidth for the terminal to measure the interference signal. Based on the above method, the terminal can measure the interference signal according to multiple forms of first configuration information configured by the access point, thereby enhancing the flexibility of the terminal in measuring the interference signal.
[0010] In combination with the first aspect and various possible implementations of the first aspect, in a third possible implementation, the request information is included in a media access control MAC frame header; or, the request information is included in a media access control MAC management frame. Based on the above method, the terminal can send the request information to the access point in various forms.
[0011] In combination with the first aspect and various possible implementations of the first aspect, in a fourth possible implementation, the first configuration information is included in a MAC frame header; or, the first configuration information is included in a MAC management frame. Based on the above method, the terminal can receive the first configuration information from the access point in various forms.
[0012] In combination with the first aspect and various possible implementations of the first aspect, in a fifth possible implementation, the request information includes a time length for which the terminal requests to measure the interference signal. Based on the above method, when requesting the access point to perform interference measurement, the terminal may send the time length for which the terminal requests to measure the interference signal to the access point, so that the access point configures the time length for the terminal to measure the interference signal based on the time length for which the terminal requests to measure the interference signal.
[0013] In a second aspect, an embodiment of the present application provides a method for receiving configuration information, the method comprising: an access point receives request information from a terminal for requesting measurement of an interference signal; the access point sends first configuration information to the terminal based on the request information, and the first configuration information is used to indicate the length of time for the terminal to measure the interference signal.
[0014] Based on the method of the second aspect described above, the access point can receive a request from a terminal and, based on the request, configure a time length for the terminal to instruct it to measure interference signals. In this process, the terminal initiates an interference measurement request. The terminal can directly measure the downlink channel and initiate an interference measurement request when downlink channel quality is poor. Compared to the access point performing downlink channel quality statistics, the terminal can perceive downlink channel changes more promptly, thereby shortening the time it takes to trigger the terminal to measure interference signals.
[0015] In conjunction with the second aspect, in a first possible implementation, the first configuration information includes a first time length for the terminal to measure the interference signal; or, the first configuration information includes a measurement period and a second time length for the terminal to measure the interference signal within the measurement period; or, the first configuration information includes the first time length for the terminal to measure the interference signal and a bandwidth for the terminal to measure the interference signal; or, the first configuration information includes a measurement period, a second time length for the terminal to measure the interference signal within the measurement period, and a bandwidth for the terminal to measure the interference signal. Based on the above method, the access point can configure multiple forms of first configuration information for the terminal, which can enhance the flexibility of the terminal in measuring the interference signal.
[0016] In conjunction with the second aspect and various possible implementations of the second aspect, in a second possible implementation, the request information is included in a media access control MAC frame header; or, the request information is included in a media access control MAC management frame. Based on the above method, the access point can receive the request information from the terminal in various forms.
[0017] In combination with the second aspect and various possible implementations of the second aspect, in a third possible implementation, the first configuration information is included in a MAC frame header; or, the first configuration information is included in a MAC management frame. Based on the above method, the access point can send the first configuration information to the terminal in various forms.
[0018] In combination with the second aspect and various possible implementations of the second aspect, in a fourth possible implementation, the method further includes: the access point stopping service transmission with the terminal; or, the access point stopping service transmission with the terminal connected to the access point. Based on the above method, when the terminal measures the interference signal, the access point can stop service transmission with the terminal, or can stop service transmission with the terminal connected to the access point. When the access point stops service transmission with the terminal connected to the access point, the impact of surrounding terminals on the terminal can be reduced, thereby improving the accuracy of the terminal's measurement of the interference signal. Although stopping service transmission with the terminal by the access point will affect the accuracy of the terminal's measurement of the interference signal, it can reduce the impact on the services of other terminals connected to the access point.
[0019] In conjunction with the fourth possible implementation manner of the second aspect, in a fifth possible implementation manner, the access point stops service transmission between terminals connected to the access point, and the method further includes: the access point sending the first configuration information to the terminals connected to the access point. Based on the above method, after the terminal initiates a measurement request to the access point, the access point may instruct all terminals connected to the access point to measure interference signals.
[0020] In conjunction with the second aspect and various possible implementations of the second aspect, in a sixth possible implementation, the request information includes a time length requested by the terminal to measure the interference signal. Based on the above method, the request information received by the access point may include the time length requested by the terminal to measure the interference signal. In this way, the access point can configure the time length for the terminal to measure the interference signal based on the time length requested by the terminal.

[0047] The implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0048] The method provided in the embodiment of the present application can be used in various communication systems. For example, the communication system can be a long term evolution (LTE) system, a fifth generation (5G) communication system, a new radio (NR) system, a WiFi system, a communication system related to the third generation partnership project (3GPP), and a communication system evolved in the future, without limitation. Figure 1B Taking the communication system 10 shown as an example, the method provided in the embodiment of the present application is described.
[0049] like Figure 1B , which is a schematic diagram of the architecture of the communication system 10 provided in an embodiment of the present application. Figure 1B In the figure, the communication system 10 may include one or more access points 101 (only one is shown) and terminals 102 to 104 that can communicate with the access point 101. Figure 1B It is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided in this application.
[0050] exist Figure 1BIn , an access point can provide wireless access services for terminals. Specifically, each access point corresponds to a service coverage area. Terminals entering the area can communicate with the access point to receive the wireless access services provided by the access point. The terminal and the access point can communicate through the link between the terminal and the access point. Among them, the link between the terminal and the access point can be divided into uplink (uplink, UL) and downlink (downlink, DL) according to the direction of the data transmitted thereon. The UL can transmit uplink data sent from the terminal to the access point, and the DL can transmit downlink data transmitted from the access point to the terminal. For example: Figure 1B In the example, the terminal 103 is located in the coverage area of the access point 101. The access point 101 can send downlink data to the terminal 103 via DL, and the terminal 103 can send uplink data to the access point 101 via UL.
[0051] Figure 1B The access point in, for example, access point 101 can be any device with wireless transceiver capabilities. Including but not limited to: evolved base stations (NodeB or eNB or e-NodeB, evolutionary Node B) in LTE, base stations (gNodeB or gNB) or transceiver points (transmission receiving point / transmission reception point, TRP) in NR, base stations of subsequent evolution of 3GPP, access nodes in WiFi systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: macro base station, micro base station, pico base station, small station, relay station, or balloon station, etc. Multiple base stations can support networks of the same technology mentioned above, or they can support networks of different technologies mentioned above. The base station can include one or more co-sited or non-co-sited TRPs. The access point can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The access point can also be a server, a wearable device, a machine communication device, or an in-vehicle device, etc. The following description uses a base station as an example of an access point. The multiple access points may be base stations of the same type or different types. A base station may communicate with a terminal or communicate with the terminal through a relay station. A terminal may communicate with multiple base stations of different technologies. For example, a terminal may communicate with a base station supporting an LTE network or a base station supporting a 5G network, and may also support dual connectivity with a base station of an LTE network and a base station of a 5G network.

Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0062] Optionally, the computer-executable instructions in the embodiments of the present application may also be referred to as application code, which is not specifically limited in the embodiments of the present application.
[0063] In a specific implementation, as an embodiment, the processor 201 may include one or more CPUs, such as Figure 2 CPU0 and CPU1 in.
[0064] In a specific implementation, as an embodiment, the communication device 200 may include multiple processors, such as Figure 2 201 and processor 207 in FIG.

[0067] The following combination Figure 1B and Figure 2 The method for receiving the configuration information provided in the embodiment of the present application is specifically described. Figure 2 Parts shown.
[0068] It should be noted that the message names between network elements or the names of parameters in the messages in the following embodiments of the present application are only examples, and other names may be used in specific implementations. The embodiments of the present application do not specifically limit this.
[0069] It should be noted that the terminal in the following embodiments of the present application may also be replaced by a relay station. The relay station may have the function of receiving and forwarding information.
[0070] It is understood that in the embodiments of the present application, a terminal or access point may perform some or all of the steps in the embodiments of the present application. These steps are merely examples, and the embodiments of the present application may also perform other steps or variations of various steps. In addition, the steps may be performed in a different order than those presented in the embodiments of the present application, and it is possible that not all of the steps in the embodiments of the present application need to be performed.
[0071] like Figure 3 As shown, a method for receiving configuration information provided in an embodiment of the present application includes steps 301 and 302.
[0072] Step 301: The terminal sends a request message to the access point.
[0073] The terminal may be Figure 1B Any terminal in terminal 102-terminal 104. The access point can be Figure 1B Access point 101 in.
[0074] The request information may be used to request the measurement of an interference signal. The request information may be named as an interference measurement request (interference measurement request) or other names, without limitation.
[0075] In a possible implementation, the request information includes a time length for which the terminal requests to measure the interference signal. For example, the request information includes 100 milliseconds (ms), indicating that the time length for which the terminal requests to measure the interference signal is 100 ms.
[0076] In another possible implementation, the request information includes an interference measurement request indication and a time length for the terminal to request to measure the interference signal.
[0077] Optionally, the request information is sent to the access point in different frame formats. Specifically, the request information can be sent to the access point in at least the following two possible implementations.
[0078] In one possible implementation, the request information is included in a media access control (MAC) frame header. For example, the request information is carried in a MAC frame header of a trigger-based (TB) physical protocol data unit (PPDU) sent by the terminal to the access point, or in a MAC frame header of a single-user (SU) PPDU sent by the terminal to the access point.
[0079] It is understood that when the request information is carried in the MAC frame header of the TB PPDU, before step 301, the terminal may receive second configuration information from the access point. This second configuration information may be used to indicate the resources where the uplink data is located. For example, the second configuration information is used to indicate at least one of the following resources: the time domain resources where the uplink data is located, the frequency domain resources where the uplink data is located, the spatial domain resources where the uplink data is located, or the modulation and coding scheme (MCS) of the uplink data. Optionally, the second configuration information may be carried in a trigger frame.
[0080] In another possible implementation, the request information is included in a MAC management frame.
[0081] For example, taking the request information including the interference measurement request indication and the time length for the terminal to request the interference signal to be measured as an example, the request information is carried in a MAC management frame sent by the terminal to the access point. The MAC management frame can be as follows: Figure 4A shown. Figure 4A In the MAC management frame, the MAC management frame includes 17 bits, wherein the first bit (B0) is used to indicate that the terminal requests to measure the interference signal, and the second to seventeenth bits (B1-B16) are used to indicate the time length for which the terminal requests to measure the interference signal.
[0082] For example, taking the example that the request information includes the time length that the terminal requests to measure the interference signal, the request information is carried in a MAC management frame sent by the terminal to the access point. The MAC management frame includes 18 bits, and the 18 bits are used to indicate the time length that the terminal requests to measure the interference signal.
[0083] It should be noted that the length of the above-mentioned MAC management frame, the length of the interference measurement request indication in the MAC management frame, or the length of the time length for the terminal to request measurement of the interference signal in the MAC management frame are only exemplary, and the embodiments of the present application do not limit the above-mentioned lengths.
[0084] The terminal can send a request message to the access point in the following situations:
[0085] Case 1: When the terminal detects that the signal quality is less than or equal to the first threshold, the terminal sends a request message to the access point.
[0086] For example, when the terminal detects that the reference signal received power (RSRP), the reference signal received quality (RSRQ), the signal to interference plus noise ratio (SINR), or the received signal strength indicator (RSSI) is less than or equal to the first threshold, the terminal sends a request message to the access point.
[0087] Case 2: When the terminal detects that the block error rate (BER) of the received data packet is greater than or equal to the second threshold, the terminal sends a request message to the access point.
[0088] The BER of the received data packet is the percentage of erroneous transmission blocks among the transmission blocks received by the terminal.
[0089] Case 3: When the terminal detects that the interference signal strength is greater than or equal to the third threshold, the terminal sends a request message to the access point.
[0090] Case 4: When the terminal detects that the duty cycle of the interference signal is greater than or equal to the fourth threshold within a period of time, the terminal sends a request message to the access point.
[0091] The duty cycle of the interference signal is the percentage of time that the terminal detects the interference signal within the period of time.
[0092] It can be understood that the above cases 1 to 4 are only exemplary, and the terminal may also send request information to the access point in other cases without limitation.
[0093] It should be noted that the embodiment of the present application does not limit the number of terminals in step 301, and the number of terminals can be one, two, or more.
[0094] Step 302: The access point receives request information from the terminal, and sends first configuration information to the terminal according to the request information.
[0095] Optionally, after receiving the request information from the terminal, the access point sends an acknowledgement (ACK) message to the terminal, where the ACK message indicates that the access point has received the request information.
[0096] Optionally, the access point sends the first configuration information to the terminal according to the request information, including: the access point determines the first configuration information according to the request information; and the access point sends the first configuration information to the terminal.
[0097] The first configuration information is used to indicate the length of time for the terminal to measure the interference signal. For an introduction to the first configuration information, refer to the following Examples 1 to 4:
[0098] Example 1: The first configuration information may include a first time length for the terminal to measure the interference signal.
[0099] Optionally, the first time length is the same as or different from the time length for which the terminal requests to measure the interference signal in the request information.
[0100] It is understandable that the access point may determine the first time length based on the current service situation. For example, if the current service volume is large, the first time length may be less than or equal to the time length for the terminal to request the interference signal measurement; if the current service volume is small, the first time length may be greater than or equal to the time length for the terminal to request the interference signal measurement.
[0101] Example 2: The first configuration information may include a measurement period and a second time length during which the terminal measures the interference signal within the measurement period.
[0102] Exemplarily, taking the first configuration information including T1 and T2, T1 being the measurement period and T2 being the second time length as an example, the access point instructs the terminal to measure the interference signal every T1, and the time length for measuring the interference signal in one measurement period is T2.
[0103] Optionally, the first configuration information further includes an offset time length. The offset time length is used to indicate the offset of the start time of measuring the interference signal relative to the start time of the measurement period within the measurement period. The offset time length is greater than or equal to 0 and less than the above-mentioned measurement period.
[0104] For example, if the first configuration information includes T1, T2, and T3, where T1 is the measurement period, T2 is the second time length, and T3 is the offset time length, the access point instructs the terminal to measure the interference signal every T1. Within a measurement period, the start time of the interference signal measurement is the sum of the start time of the period and the offset time length, and the duration of the interference signal measurement is T2. For example, if the start time of a measurement period is t1, the second time length is t2, and the offset time length is t3, then for this measurement period, the access point instructs the terminal to start measuring the interference signal at time t1+t3, and the duration of the interference signal measurement is t2.
[0105] Example 3: The first configuration information may include a first time length for the terminal to measure the interference signal and a bandwidth for the terminal to measure the interference signal.
[0106] The bandwidth in which the terminal measures the interference signal is used to indicate that the terminal measures the interference signal within that bandwidth. This allows the access point to schedule normally within other bandwidths, reducing the impact of the interference measurement on the normal service scheduling of other terminals. The first time length can be described in Example 1 above and is not further elaborated here.
[0107] Example 4: The first configuration information may include a measurement period, a second time length during which the terminal measures the interference signal within the measurement period, and a bandwidth for the terminal to measure the interference signal.
[0108] The bandwidth for measuring the interference signal by the terminal is used to instruct the terminal to measure the interference signal within the bandwidth. The introduction of the measurement period and the second time length can be referred to in the above example 2 and will not be repeated here.
[0109] Optionally, in addition to the content in Example 1, Example 2, Example 3, or Example 4 above, the first configuration information further includes feedback information and / or a third time length. The feedback information is used to indicate that the first configuration information is feedback information for the request information. For example, the feedback information is an interference measurement response. The third time length is the time length for the terminal to measure each receive beam corresponding to the antenna.
[0110] It can be understood that the first configuration information can be sent in subsequent downlink transmission.
[0111] Optionally, the first configuration information is sent to the terminal in different frame formats. Specifically, the first configuration information can be sent to the terminal in at least the following two possible implementations.
[0112] In a possible implementation, the first configuration information is included in a MAC frame header. For example, the first configuration information is carried in a MAC frame header of a SU PPDU sent by an access point to a terminal.
[0113] In another possible implementation, the first configuration information is included in a MAC management frame.
[0114] For example, taking the first configuration information including feedback information and the first time length as an example, the first configuration information is carried in a MAC management frame sent by the access point to the terminal. The MAC management frame can be as follows: Figure 4B shown. Figure 4B The MAC management frame includes 17 bits, wherein the first bit (B0) is used to indicate that the first configuration information is feedback information of the request information, and the 2nd to 17th bits (B1-B16) are used to indicate the first time length.
[0115] Exemplarily, taking the case where the first configuration information includes the first time length, the first configuration information is carried in a MAC management frame sent by the access point to the terminal. The MAC management frame includes 18 bits, and the 18 bits are used to indicate the first time length.
[0116] It should be noted that the length of the above-mentioned MAC management frame, the length of the feedback information in the MAC management frame, or the length of the first time length in the MAC management frame are only exemplary, and the embodiments of the present application do not limit the above-mentioned lengths.
[0117] Optionally, after receiving the request information from the terminal, the access point determines which terminals need to measure the interference signal.
[0118] In a possible implementation manner, the access point determines that the terminal needs to measure an interference signal.
[0119] In this case, after the access point sends the first configuration information to the terminal, the access point stops service transmission between the terminal or the access point stops all service transmissions; or, after the access point receives an ACK message of the first configuration information from the terminal, the access point stops service transmission between the terminal or the access point stops all service transmissions.
[0120] Here, the access point ceasing service transmission with the terminal means that the access point stops scheduling resources for the terminal, stops sending downlink data to the terminal, and stops receiving uplink data from the terminal. The access point ceasing all service transmission can also be replaced by the access point ceasing service transmission between the terminal and the terminal connected to the access point. The access point ceasing all service transmission means that the access point stops scheduling resources for all terminals connected to the access point, stops sending downlink data, and stops receiving uplink data.
[0121] It is understandable that if an access point stops all service transmissions, the impact of surrounding terminals on the terminal can be reduced, thereby improving the accuracy of the terminal's interference signal measurement. If an access point stops service transmission with the terminal, although the accuracy of the terminal's interference signal measurement is affected, the impact on the services of other terminals connected to the access point can be reduced.
[0122] Optionally, if the access point determines to stop service transmission with the terminal, the access point sends the first configuration information to the terminal when the service volume between the access point and the terminal is small. If the access point determines to stop all service transmissions, the access point sends the first configuration information to the terminal when the total service volume of the access point is small.
[0123] In another possible implementation, the access point determines that all or part of the terminals connected to the access point need to measure interference signals.
[0124] In this case, the access point sends the first configuration information to all or some of the terminals connected to the access point. After sending the first configuration information to all or some of the terminals connected to the access point, the access point stops all service transmissions. The description of how the access point stops all service transmissions can be found in the description above regarding when the access point determines that the terminal needs to measure interference signals, and is not further elaborated here.
[0125] Optionally, the access point determines to stop all service transmissions, and when the total amount of services on the access point is small, the access point sends the first configuration information to all or part of the terminals connected to the access point.
[0126] It should be noted that if the access point sends the first configuration information to all or part of the terminals connected to the access point, the first configuration information is included in a MAC frame header. For example, the first configuration information is carried in a MAC frame header of a multi-user (MU) PPDU sent by the access point to the terminal; or the first configuration information is included in a MAC management frame. In the case where the first configuration information is included in the MAC management frame, reference can be made to the description of the access point sending the first configuration information to the terminal in step 301, and no further description is given.
[0127] Correspondingly, the terminal receives the first configuration information from the access point; or all or part of the terminals connected to the access point receive the first configuration information from the access point.
[0128] Optionally, after receiving the first configuration information from the access point, the terminal sends an ACK message of the first configuration information to the access point, wherein the ACK message of the first configuration information is used to indicate that the terminal has received the first configuration information.
[0129] Optionally, after receiving the configuration information from the access point, all or part of the terminals connected to the access point send an ACK message of the first configuration information to the access point, wherein the ACK message of the first configuration information is used to indicate that the terminal has received the first configuration information.
[0130] based on Figure 3 In the method shown, a terminal can send a request message to an access point to request interference signal measurement. After receiving the request message, the access point can send first configuration information to the terminal based on the request message to indicate the length of time the terminal should measure the interference signal, so that the terminal can measure the interference signal based on the first configuration information. In this process, the terminal initiates the interference measurement request. The terminal can directly measure the downlink channel and initiate an interference measurement request when the downlink channel quality is poor. Compared with the access point performing downlink channel quality statistics, the terminal can perceive changes in the downlink channel more promptly, thereby shortening the time it takes to trigger the terminal to measure the interference signal.
[0131] Further optional, in Figure 3 In a possible implementation of the method shown, the terminal measures the interference signal according to the first configuration information. Figure 5 As shown, Figure 3 The method shown further includes step 303:
[0132] Step 303: The terminal measures the interference signal according to the first configuration information.
[0133] It is understandable that the content included in the first configuration information is different, and the process of the terminal measuring the interference signal according to the first configuration information is different:
[0134] For Example 1 above: if the access point stops transmitting services to the terminal or stops all service transmissions after sending the first configuration information to the terminal, the terminal begins measuring interference signals after receiving the first configuration information, and the duration of measuring the interference signals is the first duration. If the access point stops transmitting services to the terminal or stops all service transmissions after receiving an ACK message for the first configuration information from the terminal, the terminal begins measuring interference signals after sending an ACK message for the first configuration information to the access point, and the duration of measuring the interference signals is the first duration.
[0135] In a possible implementation, the terminal measures the interference signal, including: within a first time length, the terminal polls the receiving beam of the scanning antenna and measures the interference signal of each receiving beam.
[0136] Optionally, the measurement time of the terminal on each receive beam is a third time length. The third time length may be included in the first configuration information; or the third time length is pre-set or stored in the terminal.
[0137] Correspondingly, the access point stops service transmission between the terminal and the terminal or the access point stops all service transmission starting from sending the first configuration information to the terminal; or, starting from receiving the ACK message of the first configuration information from the terminal, the access point stops service transmission between the terminal and the terminal or the access point stops all service transmission.
[0138] It is understandable that after the interference signal measurement ends, that is, after the first time period from when the terminal starts measuring the interference signal, the terminal stops measuring the interference signal. Correspondingly, for the access point, after the first time period from when the access point sends the first configuration information to the terminal, the access point resumes service transmission with the terminal or resumes all service transmissions; or, after the access point receives an ACK message for the first configuration information from the terminal, the access point resumes service transmission with the terminal or resumes all service transmissions after the first time period.
[0139] Optionally, the terminal stops measuring the interference signal, including: the terminal stops scanning the receiving beam and restores to the default receiving beam.
[0140] For Example 2 above, if the access point stops transmitting services to the terminal or stops all service transmissions after sending the first configuration information to the terminal, the terminal periodically measures the interference signal after receiving the first configuration information. If the access point stops transmitting services to the terminal or stops all service transmissions after receiving an ACK message for the first configuration information from the terminal, the terminal periodically measures the interference signal after sending an ACK message for the first configuration information to the access point.
[0141] The period for the terminal to measure the interference signal is the measurement period included in the first configuration information, and the duration for the terminal to measure the interference signal in each measurement period is the second duration. The process for the terminal to measure the interference signal in each measurement period can refer to the description in Example 1 above.
[0142] It should be noted that if the first configuration information does not include the offset time length, the terminal starts measuring the interference signal at the beginning of each measurement period. If the first configuration information includes the offset time length, the terminal starts measuring the interference signal after the offset time length has passed since the beginning of each measurement period.
[0143] Correspondingly, starting from sending the first configuration information to the terminal, the access point periodically stops service transmission between the terminal or periodically stops all service transmissions; or, starting from receiving an ACK message of the first configuration information from the terminal, the access point periodically stops service transmission between the terminal or periodically stops all service transmissions.
[0144] Similarly, if the first configuration information does not include an offset time length, the access point stops service transmission to the terminal or stops all service transmission at the beginning of each measurement period. If the first configuration information includes an offset time length, the access point stops service transmission to the terminal or stops all service transmission after the offset time length has elapsed at the beginning of each measurement period.
[0145] It is understandable that in each period, after the interference signal measurement is completed, the terminal stops measuring the interference signal, and the access point resumes service transmission with the terminal or resumes all service transmissions. For details, please refer to the above example 1 and will not be repeated here.
[0146] For the above example 3, if the access point stops service transmission or all service transmissions with the terminal after sending the first configuration information to the terminal, the terminal, after receiving the first configuration information, begins measuring the interference signal within the bandwidth for measuring the interference signal at the terminal, and the duration of measuring the interference signal is the first duration. If the access point stops service transmission or all service transmissions with the terminal after receiving an ACK message for the first configuration information from the terminal, the terminal, after sending the ACK message for the first configuration information to the access point, begins measuring the interference signal within the bandwidth for measuring the interference signal at the terminal, and the duration of measuring the interference signal is the first duration.
[0147] A possible implementation method is that the terminal measures the interference signal within the bandwidth of the terminal measuring the interference signal, including: the terminal polls the receiving beam of the scanning antenna within a first time length, and measures the interference signal of each receiving beam within the bandwidth of the terminal measuring the interference signal.
[0148] Optionally, the measurement time of the terminal on each receive beam is a third time length. The third time length may be included in the first configuration information; or the third time length is pre-set or stored in the terminal.
[0149] Correspondingly, the access point stops service transmission between the terminal and the terminal or the access point stops all service transmission starting from sending the first configuration information to the terminal; or, starting from receiving the ACK message of the first configuration information from the terminal, the access point stops service transmission between the terminal and the terminal or the access point stops all service transmission.
[0150] It is understandable that after the interference signal measurement ends, that is, after the first time period from when the terminal starts measuring the interference signal, the terminal stops measuring the interference signal. Correspondingly, for the access point, after the first time period from when the access point sends the first configuration information to the terminal, the access point resumes service transmission with the terminal or resumes all service transmissions; or, after the access point receives an ACK message for the first configuration information from the terminal, the access point resumes service transmission with the terminal or resumes all service transmissions after the first time period.
[0151] Optionally, the terminal stops measuring the interference signal, including: the terminal stops scanning the receiving beam and restores to the default receiving beam.
[0152] For Example 4 above, if the access point stops transmitting services to the terminal or stops all service transmissions after sending the first configuration information to the terminal, the terminal, after receiving the first configuration information, periodically measures the interference signal within the bandwidth for measuring the interference signal at the terminal. If the access point stops transmitting services to the terminal or stops all service transmissions after receiving an ACK message for the first configuration information from the terminal, the terminal, after sending the ACK message for the first configuration information to the access point, periodically measures the interference signal within the bandwidth for measuring the interference signal at the terminal.
[0153] The period for the terminal to measure the interference signal is the measurement period included in the first configuration information, and the duration for the terminal to measure the interference signal in each measurement period is the second duration. The process for the terminal to measure the interference signal in each measurement period can refer to the description in Example 3 above.
[0154] It should be noted that if the first configuration information does not include an offset time length, the terminal begins measuring the interference signal within the bandwidth for measuring the interference signal at the beginning of each measurement period. If the first configuration information includes an offset time length, the terminal begins measuring the interference signal within the bandwidth for measuring the interference signal at the beginning of each measurement period and after the offset time length has elapsed.
[0155] Accordingly, starting from sending the first configuration information to the terminal, the access point periodically stops service transmission with the terminal or periodically stops all service transmissions within the bandwidth in which the terminal measures the interference signal; or, starting from receiving an ACK message of the first configuration information from the terminal, the access point periodically stops service transmission with the terminal or periodically stops all service transmissions within the bandwidth in which the terminal measures the interference signal.
[0156] Similarly, if the first configuration information does not include an offset time length, the access point stops service transmission to the terminal or stops all service transmission at the beginning of each measurement period. If the first configuration information includes an offset time length, the access point stops service transmission to the terminal or stops all service transmission after the offset time length has elapsed at the beginning of each measurement period.
[0157] It is understandable that in each period, after the interference signal measurement is completed, the terminal stops measuring the interference signal, and the access point resumes service transmission with the terminal or resumes all service transmissions. For details, please refer to the above example 1 and will not be repeated here.
[0158] It should be noted that if all or some of the terminals connected to the access point receive the first configuration information from the access point, then all or some of the terminals connected to the access point measure the interference signal based on the first configuration information. For an introduction to how all or some of the terminals connected to the access point measure the interference signal based on the first configuration information, reference can be made to the description of the terminal measuring the interference signal based on the first configuration information, and is not further described.
[0159] based on Figure 5 In the method shown, the terminal can measure the interference signal according to the first configuration information configured by the access point, so as to subsequently form a null-notched beam according to the measurement result to reduce the impact of the interference signal on the signal to be received by the terminal.

The above-mentioned integrated modules can be implemented in the form of hardware or software functional modules. It should be noted that the division of modules in the embodiments of the present application is illustrative and is only a logical functional division. In actual implementation, other division methods may be used.
