Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication technology, and in particular to an information transmission method, apparatus, device, storage medium, and computer program product. Background Technology
[0002] Currently, under atmospheric waveguide conditions, downlink transmissions from one base station can propagate over long distances with minimal attenuation. This delayed downlink signal can then interfere with uplink reception at another base station, resulting in long-range interference. To address this, the interfering station typically disables some downlink symbols. However, existing long-range interference management mechanisms only apply to network-wide uniform frame structure configurations and cannot handle situations where different stations use different frame structure configurations, such as different inductive frame structures between network devices. Therefore, a new long-range interference management mechanism is needed to address situations where there is no network-wide uniform frame structure configuration. Summary of the Invention

[0086] Before introducing the technical solutions of the embodiments of this application, the relevant technologies will be introduced first.
[0087] In related technologies, atmospheric waveguides can form under certain weather conditions, creating propagation channels between adjacent, distant base stations. Under atmospheric waveguide conditions, downlink transmissions from one base station can propagate over long distances with minimal attenuation, reaching distances of hundreds of kilometers. The delayed downlink signal can then affect uplink reception at another base station, resulting in long-range interference.
[0088] See Figure 1A , Figure 1A This is a schematic diagram of remote interference in related technologies, such as... Figure 1A As shown, remote base station interference signals have certain characteristics. The interfering stations or the stations that cause remote interference are multiple base stations. These multiple base stations are at different distances from the affected station. After the time delays are superimposed, the interference to the affected station is stepped. When the affected station detects stepped interference, it can be determined that remote interference has occurred.
[0089] See Figure 1B , Figure 1BThis is a schematic diagram of interference management in related technologies, such as... Figure 1B As shown, atmospheric waveguides are relatively rare, but they can have a significant impact on network performance. When interference occurs, the solution to the problem of interference to remote network equipment is to have the interfering station shut down some downlink symbols.
[0090] Currently, the method of dynamically disabling downlink symbols through instructions is called a remote interference management mechanism. Current interference management mechanisms are divided into the following three types:
[0091] The first option is centralized remote interference management.
[0092] See Figure 1C , Figure 1C This is a schematic diagram of interference management in related technologies, such as... Figure 1C As shown, after detecting interference, the affected station transmits a Remote Interference Management-Reference Signal (RIM-RS) type 1. Due to channel reciprocity, the interfering station can detect RIM-RS type 1 and, upon receiving it, reports the detection to the Operation Administration and Maintenance (OAM) system. The OAM then provides the interfering station with an interference mitigation plan, and the interfering station disables downlink interference symbols. When the atmospheric waveguide disappears, the interfering station can no longer receive RIM-RS and will also report this to the OAM. The OAM will then instruct the interfering station to resume its original downlink transmission and instruct the affected station to stop transmitting RIM-RS.
[0093] In this context, a distributed framework is preferable for simplicity and to reduce OAM signaling.
[0094] The second approach is to use distributed remote interference management via air interface signaling.
[0095] See Figure 1D , Figure 1D This is a schematic diagram of interference management in related technologies, such as... Figure 1D As shown, after the affected station detects interference, it sends RIM-RS type 1. The interfering station also detects RIM-RS type 1. Then, the interfering station will autonomously decide on an interference mitigation plan, such as prematurely shutting downlink transmission and simultaneously sending air interface signaling RIM-RS type 2 to enable the affected station to stop sending RIM-RS type 1. When the atmospheric waveguide disappears, the interfering station can no longer detect RIM-RS type 1 and resumes downlink transmission; the affected station can no longer detect RIM-RS type 2 and stops sending RIM-RS type 1.
[0096] The third approach is to use distributed remote interference management with backhaul signaling.
[0097] See Figure 1E , Figure 1E This is a schematic diagram of interference management in related technologies, such as... Figure 1E As shown, for the third scheme, the steps for the affected station to send RIM-RS type 1 are the same as in the first and second schemes. The disrupting station notifies the affected station of the following information via the return signaling of the Xn interface: whether the disrupting station can detect RIM-RS type 1. If the return signaling indicates that RIM-RS type 1 cannot be detected, the affected station stops sending RIM-RS type 1.
[0098] It should be noted that RIM-RS Type 1 is sent at the end of the downlink symbol to ensure that the interfering station can receive it normally. RIM-RS Type 1 (RIM-RS1) indicates the presence of interference from remote network equipment and the identifier of the interfered cell (group). It may also include the number of interfering symbols received at the beginning of the uplink cycle. This information is encoded into the time domain, frequency domain, and sequence domain of RIM-RS Type 1. RIM-RS Type 2 (RIM-RS2) only indicates the presence of remote interference.
[0099] See Figure 1F , Figure 1F This is a schematic diagram of the synesthetic frame structure configuration in related technologies, such as... Figure 1F As shown, for cooperative sensing, the general frame structure configuration is to place the sensing symbol in the last downlink symbol. This is because the time delay from the sensing transmitting base station to the sensing receiving base station may exceed the coverage distance of the cyclic prefix (CP). If the sensing receiving symbol is followed by a communication symbol, it will interfere with the communication symbol. Therefore, the sensing symbol is placed in the last downlink symbol. After the last sensing symbol is the guard interval, there is no inter-symbol interference problem.
[0100] In summary, firstly, existing remote interference management mechanisms are only applicable to situations where the entire network has a unified frame structure configuration, i.e., applicable to the communication frame structure. They are not applicable to situations where different stations use different frame structure configurations, such as network devices using different sensing frame structure configurations. Therefore, to achieve remote interference management for sensing frame structures, a remote interference management mechanism specifically for sensing frame structures is needed. Secondly, the design scheme should minimize the number of symbols shut down by interfering stations, thereby improving resource utilization and minimizing the impact on sensing performance.
[0101] See Figure 2 , Figure 2 This is a schematic diagram illustrating the implementation flow of the information transmission method according to an embodiment of this application, applied to a first network device, such as... Figure 2 As shown, the method includes step 201:
[0102] Step 201: The first network device receives a first signal and a first indication information sent by the second network device; wherein, the first signal is used to indicate that the first network device is interfering with the remote network device, and the first indication information is used to indicate the first frame structure configuration of the second network device.
[0103] It is understood that the first network device may refer to the interfering network device under the atmospheric waveguide, the second network device may refer to the disturbed network device under the atmospheric waveguide, and the first network device interfering with the remote network device may refer to the first network device interfering with the second network device.
[0104] It is understood that the first signal may refer to the Remote Interference Management-Reference Signal (RIM-RS), specifically the Remote Interference Management-Reference Signal Type 1 (RIM-RS1).
[0105] It is understood that the first signal can indicate the interference situation of the second network device and / or indicate the number of downlink symbols that the first network device needs to turn off. The first network device turns off the corresponding downlink symbols according to the interference situation of the second network device and / or the number of downlink symbols that the first network device needs to turn off, so as to reduce the interference to the uplink reception of the second network device, thereby realizing remote interference management.
[0106] It is understandable that when the second network device sends the first signal and the first indication information, the first network device can receive the first signal and the first indication information sent by the second network device because the current symbol in the frame structure configuration of the first network device can be used for reception.
[0107] In order to achieve interference management of the synesthetic frame structure, it is necessary to design a remote interference management mechanism for synesthetics. Therefore, in this application, when the second network device detects remote interference, in addition to sending the first signal to the first network device, the second network device also sends the first frame structure configuration of the second network device to the first network device. The first frame structure configuration can refer to the synesthetic frame structure.
[0108] In some embodiments, the first frame structure configuration of the second network device includes:
[0109] Sensing the structure of the received frame;
[0110] or,
[0111] Perceive the structure of the transmitted frame.
[0112] It is understood that the sensing reception frame structure can refer to a frame structure containing sensing reception time slots or sensing reception symbols. The sensing transmission frame structure can refer to a frame structure containing sensing transmission time slots or sensing transmission symbols.
[0113] In other words, the second network device, i.e., the disturbed station, has two possible frame structures: a sensing-transmitting frame structure and a sensing-receiving frame structure. Different frame structures correspond to different disturbance situations. Therefore, in addition to reporting the first signal, it is also necessary to report the first frame structure configuration of the second network device. Since there are two frame structure configurations, only one bit of the first indication information is needed to indicate this. For example, if the first bit in the first indication information is equal to 1, it indicates that the first frame structure of the second network device is configured as a sensing-receiving frame structure; if the first bit in the first indication information is equal to 0, it indicates that the first frame structure of the second network device is configured as a sensing-transmitting frame structure. Alternatively, sending the first indication information indicates a sensing-receiving frame structure, while not sending the first indication information indicates a sensing-transmitting frame structure.
[0114] Here, the first frame structure configuration of the second network device indicated by the first indication information can be a sensing receive frame structure or a sensing send frame structure. In this way, when the second network device adopts different frame structure configurations, remote interference management for the second network device can be realized based on the first signal, that is, remote interference management under non-network-wide unified frame structure configuration can be realized.
[0115] In practical applications, under atmospheric waveguide conditions, the remote interference network consists of multiple network devices. These multiple network devices are at different distances from the interfered network device (i.e., the second network device), and the frame structure configurations of the multiple interfering network devices are different. That is, some interfering network devices are configured with a sensing frame structure, including both sensing-receiving and sensing-transmitting frame structures, while others are configured with a communication frame structure. Thus, when the second network device sends a first signal, some interfering network devices can receive the first signal, while others cannot. To avoid the problem in related technologies where some interfering network devices cannot receive the remote interference management reference signal sent by the interfered network device and therefore cannot achieve remote interference management, in this application, after the first network device receives the first signal sent by the second network device, it instructs other interfering network devices to interfere with the remote network device through a second signal.
[0116] Based on this, in some embodiments, the method further includes:
[0117] The first network device sends a second signal to at least one third network device; wherein the second signal is used to instruct at least one of the third network devices to interfere with the remote network device.
[0118] It is understood that the third network device may refer to an interference network device under atmospheric waveguide, and the third network device may be a sensing network device that cooperates with the first network device for sensing, or a communication network device.
[0119] It is understood that the first network device can determine the third network device to send the second signal based on the interference situation of the second network device indicated by the first signal.
[0120] It is understood that the second signal may be the same as the first signal, that is, it may be a remote interference management reference signal (RIM-RS), specifically a remote interference management reference signal type 1 (RIM-RS1), or the second signal may be different from the first signal.
[0121] It is understood that the second signal can indicate the interference situation of the second network device and the number of symbols that the third network device needs to turn off. The third network device reduces the interference to the uplink reception of the second network device by turning off the symbols, thereby realizing remote interference management.
[0122] It is understandable that the first network device can send a second signal to at least one third network device via Xn signaling.
[0123] In practical applications, the first network device can send the second signal to one or more third network devices.
[0124] Accordingly, in some embodiments, there are multiple third network devices; sending the second signal to at least one third network device includes:
[0125] The first network device sends the second signal to the network device group; wherein the network device group is formed by multiple third network devices and the first network device, the distance between the third network devices and the first network device meets a preset condition, and the network device group includes communication network devices and / or sensing network devices.
[0126] It is understood that when the first network device sends the second signal to the network device group, it may mean sending the second signal to other third network devices in the network device group besides the first network device.
[0127] It is understood that the distance between the third network device and the first network device meets the preset condition, which may mean that the distance between the third network device and the first network device is less than or equal to a preset threshold.
[0128] See Figure 3 , Figure 3 This is a schematic diagram of the first frame structure configuration of the second network device according to an embodiment of this application, as shown below. Figure 3 As shown, the second network device is represented by the interfered station B, the first network device is represented by the interfering station D, and the third network device is represented by the interfering station C. The first frame structure of the interfered station B is configured as a sensing and receiving frame structure. It can be seen that for the sensing and receiving frame structure configuration of the interfered station B, a part of the sensing and receiving time slot Us is simultaneously interfered by the far-end interference of the interfering station D and the interfering station C, and another part of the sensing and receiving time slot Us is interfered by the far-end interference of the interfering station C.
[0129] See Figure 4 , Figure 4 This is a schematic diagram of the first network device receiving the first signal and the first indication information according to an embodiment of this application, as shown below. Figure 4 As shown, the first network device is represented by interfering station D, the second network device by the interfered station B, and the third network device by interfering station C. When interference occurs from a remote network device, the interfered station B is interfered with by interfering stations C and D. If interference management is performed according to the existing method, that is, when the interfered station B is interfered with by interfering stations C and D, the interfered station B sends RIM-RS1. The current symbol in the frame structure configuration of interfering station D can be used for reception, so interfering station D can receive the RIM-RS1 sent by the interfered station B. However, the current symbol in the frame structure configuration of interfering station C cannot be used for reception, so interfering station C cannot receive the RIM-RS1 sent by the interfered station B. It can be seen that according to the existing RIM mechanism to mitigate interference, since interfering station C cannot receive RIM-RS1, interfering station C cannot perform interference management. Therefore, in this application, after the affected station B detects interference from the remote network device, it sends a first signal such as RIM-RS1 and a first indication information. The interfering station D can receive the first signal such as RIM-RS1 and the first indication information, while the sensing transmission symbol (Ds) of the interfering station C cannot be used for reception. Therefore, the interfering station C cannot receive the first signal such as RIM-RS1 and the first indication information. Thus, after receiving the first signal such as RIM-RS1, the interfering station D determines the affected station C to send a second signal based on the interference situation of the affected station B indicated by the first signal, and uses Xn signaling to indicate the second signal such as RIM-RS1 to the interfering station C, so as to indicate that the interfering station C has interfered with the affected station B, thereby enabling both the interfering station D and the interfering station C to achieve remote interference management.
[0130] See Figure 5 , Figure 5 This is a schematic diagram illustrating the first network device sending a second signal to a group of network devices according to an embodiment of this application. Figure 5As shown, the first network device is represented by interference station D, the second network device is represented by interference station B, and the network device group is represented by interference station C and interference station E. Interference station C is a sensing network device, and interference station E is a pure communication network device. In this case, based on experience, the sensing receiving station, i.e., interference station D, and sensing network devices such as interference station C and communication network devices such as interference station E within a certain distance range can be classified into a network device group. It is assumed that the interference generated within this network device group is basically the same. Thus, when the sensing receiving station, i.e., interference station D, within this network device group receives the first signal such as RIM-RS1 and the first indication information, it can use Xn signaling to instruct the second signal to other network devices within the same network device group, such as interference station C and interference station E, for interference management.
[0131] In practical applications, when a disturbed network device is subjected to remote interference from an interfering network device, the interfering network device can reduce the remote interference to the disturbed network device by turning off the downlink symbol. However, in some cases, the interfering network device needs to turn off the sensing downlink symbol, which will reduce the sensing performance. In order to reduce the impact on the sensing performance, in this application, after the disturbed network device is subjected to remote interference from an interfering network device, it can also reduce the remote interference by changing the position of the interfered sensing symbol.
[0132] Based on this, in some embodiments, the method further includes:
[0133] When the first network device detects that the first sensing time slot and / or the first sensing symbol in the frame structure configuration of the first network device are subject to remote interference, the first network device adjusts the position of the first sensing time slot and / or the first sensing symbol in the frame structure configuration of the first network device.
[0134] It is understandable that, since the channel is reciprocal, the interfering network device can also be the affected network device. Therefore, when the first network device is subjected to remote interference, the second network device can be the interfering network device under the atmospheric waveguide, and the first network device is the affected network device under the atmospheric waveguide.
[0135] It is understood that the first sensing time slot may refer to a sensing time slot used for receiving, or be described as an uplink sensing time slot, and the first sensing symbol may refer to a sensing symbol used for receiving, or be described as an uplink sensing symbol.
[0136] In some embodiments, adjusting the position of the first sensing time slot and / or the first sensing symbol in the frame structure configuration of the first network device includes:
[0137] The first sensing time slot is placed at the beginning of the consecutive downlink time slots in the frame structure configuration of the first network device; and / or, the first sensing symbol is placed at the beginning of the consecutive downlink symbols in the frame structure configuration of the first network device.
[0138] It is understood that the beginning of a series of downlink time slots in the frame structure configuration can refer to the beginning of a series of downlink time slots in a period of the frame structure configuration.
[0139] It is understood that the beginning of consecutive downlink symbols in the frame structure configuration may refer to the beginning of consecutive downlink symbols in a period of the frame structure configuration.
[0140] For example, suppose a period in the frame structure configuration of the first network device includes DDUsFU, where D represents downlink time slot, Us represents uplink sensing time slot, F represents flexible time slot, and U represents uplink time slot. If the first network device detects that the first sensing time slot, i.e., Us, is subject to remote interference, then the first sensing time slot, i.e., Us, is placed at the beginning of two consecutive downlink time slots, i.e., adjusted to UsDDFU.
[0141] It should be noted that adjusting the position of the first sensing symbol is similar to adjusting the position of the first sensing time slot, and will not be described again here.
[0142] In practical applications, after the first network device adjusts the position of the first sensing time slot and / or the first sensing symbol in the frame structure configuration of the first network device, it is also necessary to instruct other network devices that cooperate with the first network device to adjust the corresponding sensing positions.
[0143] Based on this, in some embodiments, the method further includes:
[0144] The first network device sends a second indication information to at least one fourth network device; wherein the second indication information is used to instruct at least one of the fourth network devices to adjust the position of the second sensing time slot and / or the second sensing symbol in the frame structure configuration of the fourth network device; the second sensing time slot corresponds to the first sensing time slot, and the second sensing symbol corresponds to the first sensing symbol.
[0145] It is understood that the fourth network device is a sensing network device that cooperates with the first network device to sense information.
[0146] It is understood that the second sensing time slot may refer to a sensing time slot used for transmission, or be described as a downlink sensing time slot, and the second sensing symbol may refer to a sensing symbol used for transmission, or be described as a downlink sensing symbol.
[0147] For example, suppose that a period in the frame structure configuration of the first network device includes DDUsFU, and a period in the frame structure configuration of the fourth network device includes DDDsFU, where D represents downlink time slot, Us represents uplink sensing time slot, Ds represents downlink sensing time slot, F represents flexible time slot, and U represents uplink time slot. If the first network device detects that the first sensing time slot, i.e., Us, is subject to remote interference, it places the first sensing time slot, i.e., Us, at the beginning of two consecutive downlink time slots, i.e., adjusts it to UsDDFU, and instructs the fourth network device to place the second sensing time slot, i.e., Ds, corresponding to the first sensing time slot, i.e., Us, at the beginning of two consecutive downlink time slots, i.e., adjusts it to DsDDFU.
[0148] It should be noted that adjusting the position of the second sensing time slot and / or the second sensing symbol is similar to adjusting the position of the first sensing time slot and / or the first sensing symbol, and will not be repeated here.
[0149] Similarly, in the event of remote interference to the second network device, if the second network device detects remote interference to the third sensing time slot and / or the third sensing symbol in its first frame structure configuration, it places the third sensing time slot at the beginning of the consecutive downlink time slots in the first frame structure configuration, and / or places the third sensing symbol at the beginning of the consecutive downlink symbols in the first frame structure configuration. Simultaneously, the second network device also needs to instruct at least one fifth network device to adjust the position of the fourth sensing time slot and / or the fourth sensing symbol in the frame structure configuration of the fifth network device, wherein the fifth network device is a sensing network device that cooperates with the second network device in sensing.
[0150] In practical applications, after being interfered with from a remote network device, the affected network device can reduce the remote interference by changing the position of the interfered sensing symbol in the time slot. However, the affected network device still needs the instruction from the interfering network device to restore the original frame structure configuration.
[0151] Based on this, in some embodiments, the method further includes:
[0152] The first network device receives a first signaling sent by the second network device; wherein the first signaling is used to indicate that the second network device is subjected to remote interference;
[0153] The first network device sends a second signaling message to the second network device; wherein the second signaling message is used to indicate that the first network device can receive the first signaling message;
[0154] The second network device restores its original frame structure configuration until it no longer receives the second signaling sent by the first network device.
[0155] It is understandable that after the second network device restores the original frame structure configuration, it can also instruct other network devices that cooperate with the second network device to restore the original frame structure configuration.
[0156] Understandably, if the second network device is subject to remote interference, it can change its sensing location. If there is no remote sensing interference after changing the sensing location, but communication interference exists, the initial configuration is restored as follows: Specifically, if the symbol ratio of the flexible timeslot F configuration in the frame structure configuration of the second network device includes uplink signals, then there is no need to separately configure signaling to indicate the presence / disappearance of interference. The first signal triggered by communication indicates the presence of interference, and the original frame structure configuration is restored after the interference disappears. If there is remote sensing interference after changing the sensing location, but no communication interference, the initial configuration is restored as follows: Specifically, if the symbol ratio of the flexible timeslot F configuration in the frame structure configuration of the second network device does not include uplink signals, then the second network device indicates the presence of interference through the first signaling, and the first network device replies with the second signaling until the interference disappears. At this point, the second network device no longer receives the second signaling, and the original frame structure configuration is restored.
[0157] It is understandable that, since the channel is reciprocal, the interfering network device will also be the affected network device. Therefore, the way the first network device restores the original frame structure configuration is similar to the way the second network device restores the original frame structure configuration, and will not be described in detail here.
[0158] See Figure 6 , Figure 6 This is a schematic diagram of the first frame structure configuration of the second network device according to an embodiment of this application, as shown below. Figure 6 As shown, the first network device is represented by interfering station D, the second network device by the interfered station B, and the third network device by interfering station C. The first frame structure of the interfered station B is configured as a sensing and receiving frame structure. It can be seen that when an atmospheric waveguide is present, the downlink interference signals from the remote network devices, i.e., interfering stations C and D, arrive at the interfered stations A and B after a certain time delay, thus causing interference from the remote network devices to the uplink reception of the interfered station B. Since the distance between D and Us in the sensing and receiving station frame structure is very close, the sensing and receiving station B, as the interfered station, will be subject to significant remote interference. The second downlink time slot of interfering stations C and D interferes with station B, and these two slots should be closed to avoid interference. At the same time, when the sensing and transmitting station C acts as an interfering station, in some cases, remote interference management may need to prioritize closing the sensing downlink symbol, which also has a significant impact on sensing performance. To reduce interference, the sensing time slot position can be changed.
[0159] See Figure 7 , Figure 7 This is a schematic diagram illustrating the replacement of the sensing time slot position in an embodiment of this application, as shown below. Figure 7 As shown, the first network device is represented by interfering station D, the second network device by interfered station B, the third network device by interfering station C, and the fifth network device by interfered station A. To reduce the interference of remote network devices on the sensing signal, when interfered station B detects that the first sensing time slot (Us) is interfered with, it changes the position of Us. Assuming that one period in the frame structure configuration of interfered station B includes DDUsFU, if interfered station B detects that Us is interfered with from a remote location, it places Us at the beginning of two consecutive downlink time slots, i.e., adjusts it to UsDDFU, and swaps the position of the corresponding second sensing time slot with interfered station A, which is cooperating with it in sensing. Assuming that one period in the frame structure configuration of interfered station A includes DDDsFU, it adjusts it to DsDDFU. Because the channel is reciprocal, the interfering station can also be an interfered station. Therefore, interfering stations C and D can also change the position of the sensing time slot when they detect interference, in a similar way to interfered stations B and A. With the sensing signal placed after the first slot, the number of interfered symbols for the affected station B is reduced to 0 because the sensing symbol is preceded by an uplink symbol. Although this configuration causes the sensing station B to affect adjacent communication symbols (occupying 1 symbol) due to latency when receiving the sensing signal, the benefits outweigh the losses compared to the multiple symbols that need to be shut down for remote interference.
[0160] See Figure 8 , Figure 8 This is a schematic diagram of the first network device receiving the first signaling according to an embodiment of this application, as shown below. Figure 8As shown, the first network device is represented by interfering station D, the second network device by the affected station B, and the third network device by interfering station C. If there is no remote sensing interference after changing the sensing time slot location, but there is communication interference, when to restore the initial configuration? If the flexible time slot F in the frame structure configuration of the affected station B is configured with a symbol ratio of 10D:2F:2U, and one time slot consists of 14 symbols, and the 14 symbols corresponding to the F time slot are DDDDDDDDDDFFUU, then there is remote communication interference. There is no need to configure signaling to indicate the presence / disappearance of sensing interference. The first signal triggered by communication, such as RIM-RS, will indicate the presence of interference. After the interference disappears, the original frame structure configuration is restored. If there is remote sensing interference after changing the sensing slot location, but no communication interference, when should the initial configuration be restored? If the symbol ratio of the flexible slot F configuration of the disturbed station B does not include uplink symbols, then there is no remote communication interference. The disturbed station B sends a first signaling on the last downlink slot to indicate the presence of interference. The first signaling is similar to RIM-RS1, but does not need to indicate much information; it only needs to indicate that the interference exists. After receiving the first signaling sent by the disturbed station B, the interfering stations C and D send a second signaling to the disturbed station B on the symbol of the last downlink slot. The second signaling is used to indicate that the first signaling can be received, that is, to indicate that the remote interference still exists. Until the atmospheric waveguide disappears, the interfering stations C and D no longer receive the first signaling sent by the disturbed station B, restore the original frame structure configuration, and stop sending the second signaling to the disturbed station B. When the disturbed station B no longer receives the second signaling, the disturbed station B restores the original frame structure configuration and instructs the disturbed station A, which is cooperating with the disturbed station B in sensing, to restore the original frame structure configuration.
[0161] In practical applications, after the second network device changes its sensing location as the disturbed network device, it also needs to send the adjusted frame structure configuration to the first network device so that the first network device can manage the interference.
[0162] Based on this, in some embodiments, the method further includes:
[0163] The first network device receives third indication information sent by the second network device; wherein the third indication information is used to indicate the second frame structure configuration of the second network device.
[0164] In some embodiments, the second frame structure configuration of the second network device includes:
[0165] The adjusted sensing and receiving frame structure.
[0166] It is understood that after receiving the third indication information, the first network device will, based on the interference situation of the second network device indicated by the first signal and / or the number of symbols that need to be turned off, as well as the adjusted sensing and receiving frame structure of the second network device, turn off the corresponding downlink symbols to reduce remote interference to the second network device.
[0167] See Figure 9 , Figure 9 This is a schematic diagram of interference management in an embodiment of this application, as shown below. Figure 9 As shown, the first network device is represented by interfering station D, the second network device by the affected station B, and the third network device by interfering station C. The first frame structure of affected station B is configured as a sensing and receiving frame structure. It can be seen that when an atmospheric waveguide is present, the downlink interference signals from the remote network devices, namely interfering stations C and D, arrive at affected stations A and B after a certain time delay, thereby causing interference to the uplink reception of affected station B by the remote network devices. After receiving the first signal and the first indication information sent by affected station B, interfering station D closes the corresponding downlink symbols to reduce the remote interference to affected station B based on the interference situation of affected station B indicated by the first signal and / or the number of symbols that interfering station D needs to close. At the same time, interfering station D also sends a second signal to interfering station C. The second signal is used to indicate the interference situation of affected station B and / or the number of symbols that interfering station C needs to close. Interfering station C closes the corresponding downlink symbols to reduce the remote interference to affected station B based on the interference situation of affected station B indicated by the second signal and / or the number of symbols that interfering station C needs to close.
[0168] See Figure 10 , Figure 10 This is a schematic diagram of interference management in an embodiment of this application, as shown below. Figure 10 As shown, the first network device is represented by interfering station D, the second network device by interfered station B, the third network device by interfering station C, and the fifth network device by interfered station A. When interfered stations A and B detect interference with the sensing symbol, they change the position of their sensing slots. Assuming that one period in the frame structure configuration of interfered station B includes DDUsFU, if interfered station B detects that the first sensing slot, Us, is subject to far-end interference, it places Us at the beginning of two consecutive downlink slots, i.e., adjusts it to UsDDFU. The flexible slot F is configured with the flexible symbol F (actually the guard interval GP, which does not call resources on this symbol) and U. Interfered station B also instructs its cooperating sensing partner, interfered station A, to change its sensing slot position. Because the channel is reciprocal, the interfering station is also a interfered station. Therefore, interfering stations C and D will also change their sensing slot positions, similar to those of interfered stations B and A. Changing the sensing position reduces interference.
[0169] See Figure 11 , Figure 11 This is a schematic diagram of the first network device receiving third instruction information according to an embodiment of this application. Figure 11 As shown, the first network device is represented by interfering station D and interfering station C, and the second network device is represented by affected station A and affected station B. After changing the sensing location, the interference decreases, but it still exists. Therefore, an interference management process is needed. That is, after interference occurs, affected station A and affected station B need to send a first signal such as RIM-RS1. After receiving the first signal RIM-RS1, interfering station C and interfering station D can know their actual transmission time and frequency location, and thus know the transmission and reception delay. If the affected station is a sensing station (i.e., affected station A) or a communication station (corresponding to station A's frame structure), only the communication symbols are interfered with. It is only necessary to disable a certain number of symbols by indicating the original first signal such as RIM-RS1. If the affected station is a sensing receiving station, i.e., affected station B (corresponding to station B's frame structure), the original first signal, such as RIM-RS1, is insufficient to inform interfering stations C and D to disable the first few downlink sensing symbols. Therefore, an additional third indication is needed. This third indication tells affected station B the adjusted sensing receiving frame structure. When interfering stations C and D simultaneously receive both the first signal (RIM-RS1) and the third indication, they know the affected station is a sensing receiving station. Based on the interference situation at affected station B and / or the number of symbols to be disabled, interfering stations C and D disable a certain number of downlink symbols, effectively mitigating interference from remote network equipment. After receiving the first signal (RIM-RS1), interfering stations C and D report the presence of remote interference via the Xn interface. When the atmospheric waveguide disappears, interfering stations C and D no longer receive the first signal (RIM-RS1), and restore the original frame structure configuration, reporting the absence of remote interference to affected station B via the Xn interface. Disturbed station A and disturbed station B stop sending the first signal, such as RIM-RS1, and restore the original frame structure configuration.
[0170] The embodiments of this application have the following advantages:
[0171] (1) When introducing sensing, considering that the problem of interference with remote base stations cannot be solved by existing solutions, this application proposes a remote interference management method based on a sensing frame structure. The first frame structure configuration of the second network device indicated by the first indication information can be a sensing receiving frame structure or a sensing transmitting frame structure. Thus, when the second network device adopts different frame structure configurations, remote interference management for the second network device can be achieved based on the first signal, that is, remote interference management can be achieved for different sensing frame structure configurations.
[0172] (2) After detecting remote interference, the second network device sends a first signal and a first indication message to the first network device. The second network device can receive the first signal. If the third network device cannot receive the first signal, the second network device can use Xn signaling to instruct the third network device to send a second signal for interference management. Alternatively, the second network device and sensing network devices and communication network devices within a certain distance range can be grouped into a network device group, assuming that the interference generated within this group is essentially the same. When the second network device in this group receives the first signal, it will instruct other network devices in the same group to perform interference management via Xn signaling.
[0173] (3) Upon detecting remote interference, the affected station, i.e., the second network device, can change its sensing location to reduce the number of symbols affected by the remote interference, improve the utilization rate of time and frequency resources, and reduce the impact on sensing performance. If sensing interference still exists after changing the sensing location, a third indication information is added to indicate the adjusted frame structure configuration of the affected station, which, together with the first signal, indicates the sensing interference. After changing the sensing location, the first and second signaling are used to indicate the presence or disappearance of the atmospheric waveguide, so as to indicate when to restore the original frame structure configuration. By designing interference management signaling suitable for the sensing frame structure, effective remote interference management is achieved.
[0174] See Figure 12 , Figure 12 This is a schematic diagram illustrating the implementation flow of the information transmission method according to an embodiment of this application, applied to a second network device, such as... Figure 12 As shown, the method includes step 1201:
[0175] Step 1201: The second network device sends a first signal and a first indication information to the first network device; wherein, the first signal is used to indicate that the first network device is interfering with the remote network device, and the first indication information is used to indicate the first frame structure configuration of the second network device.
[0176] It is understood that the first network device may refer to the interfering network device under the atmospheric waveguide, the second network device may refer to the disturbed network device under the atmospheric waveguide, and the first network device interfering with the remote network device may mean that the first network device interferes with the second network device.
[0177] It is understood that the first signal may refer to the Remote Interference Management-Reference Signal (RIM-RS), specifically the Remote Interference Management-Reference Signal Type 1 (RIM-RS1).
[0178] It is understood that the first signal can indicate the interference situation of the second network device and / or indicate the number of downlink symbols that the first network device needs to turn off. The first network device turns off the corresponding downlink symbols according to the interference situation of the second network device and / or the number of downlink symbols that the first network device needs to turn off, so as to reduce the interference to the uplink reception of the second network device, thereby realizing remote interference management.
[0179] It is understandable that when the second network device sends the first signal and the first indication information, the first network device can receive the first signal and the first indication information sent by the second network device because the current symbol in the frame structure configuration of the first network device can be used for reception.
[0180] In order to achieve interference management of the synesthetic frame structure, it is necessary to design a remote interference management mechanism for synesthetics. Therefore, in this application, when the second network device detects remote interference, in addition to sending the first signal to the first network device, the second network device also sends the first frame structure configuration of the second network device to the first network device. The first frame structure configuration can refer to the synesthetic frame structure.
[0181] In some embodiments, the first frame structure configuration of the second network device includes:
[0182] Sensing the structure of the received frame;
[0183] or,
[0184] Perceive the structure of the transmitted frame.
[0185] It is understood that the sensing reception frame structure can refer to a frame structure containing sensing reception time slots or sensing reception symbols. The sensing transmission frame structure can refer to a frame structure containing sensing transmission time slots or sensing transmission symbols.
[0186] In practical applications, when a disturbed network device is subjected to remote interference from an interfering network device, the interfering network device can reduce the remote interference to the disturbed network device by turning off the downlink symbol. However, in some cases, the interfering network device needs to turn off the sensing downlink symbol, which will reduce the sensing performance. In order to reduce the impact on the sensing performance, in this application, after the disturbed network device is subjected to remote interference from an interfering network device, it can also reduce the remote interference by changing the position of the interfered sensing symbol.
[0187] Based on this, in some embodiments, the method further includes:
[0188] When the second network device detects that the third sensing time slot and / or the third sensing symbol in the first frame structure configuration of the second network device are subject to remote interference, the second network device adjusts the position of the third sensing time slot and / or the third sensing symbol in the first frame structure configuration.
[0189] In some embodiments, adjusting the position of the third sensing slot and / or the third sensing symbol in the first frame structure configuration includes:
[0190] The third sensing time slot is placed at the beginning of the consecutive downlink time slots in the first frame structure configuration;
[0191] And / or,
[0192] The third sensing symbol is placed at the beginning of the consecutive downlink symbols in the first frame structure configuration.
[0193] It is understood that the beginning of a series of downlink time slots in the frame structure configuration can refer to the beginning of a series of downlink time slots in a period of the frame structure configuration.
[0194] It is understood that the beginning of consecutive downlink symbols in the frame structure configuration may refer to the beginning of consecutive downlink symbols in a period of the frame structure configuration.
[0195] For example, suppose a period in the frame structure configuration of the second network device includes DDUsFU, where D represents the downlink time slot, Us represents the uplink sensing time slot, F represents the flexible time slot, and U represents the uplink time slot. If the second network device detects that the third sensing time slot, i.e., Us, is subject to remote interference, then the third sensing time slot, i.e., Us, is placed at the beginning of two consecutive downlink time slots, i.e., adjusted to UsDDFU.
[0196] It should be noted that adjusting the position of the third sensing symbol is similar to adjusting the position of the third sensing time slot, and will not be described again here.
[0197] In practical applications, after the second network device adjusts the position of the third sensing time slot and / or the third sensing symbol in the first frame structure configuration of the second network device, it is also necessary to instruct other network devices that cooperate with the second network device to adjust the corresponding sensing positions.
[0198] Based on this, in some embodiments, the method further includes:
[0199] Send a fourth indication message to at least one fifth network device; wherein the fourth indication message is used to instruct at least one fifth network device to adjust the position of the fourth sensing time slot and / or the fourth sensing symbol in the frame structure configuration of the fifth network device, the fourth sensing time slot corresponding to the third sensing time slot, and the fourth sensing symbol corresponding to the third sensing symbol.
[0200] It is understood that the fifth network device is a sensing network device that cooperates with the second network device to sense information.
[0201] It is understood that the fourth sensing time slot may refer to a sensing time slot used for transmission, or be described as a downlink sensing time slot, and the fourth sensing symbol may refer to a sensing symbol used for transmission, or be described as a downlink sensing symbol.
[0202] For example, suppose that a period in the frame structure configuration of the second network device includes DDUsFU, and a period in the frame structure configuration of the fifth network device includes DDDsFU, where D represents downlink time slot, Us represents uplink sensing time slot, Ds represents downlink sensing time slot, F represents flexible time slot, and U represents uplink time slot. If the second network device detects that the third sensing time slot, i.e., Us, is subject to remote interference, it places the third sensing time slot, i.e., Us, at the beginning of two consecutive downlink time slots, i.e., adjusts it to UsDDFU, and instructs the fifth network device to place the fourth sensing time slot, i.e., Ds, corresponding to the third sensing time slot, i.e., Us, at the beginning of two consecutive downlink time slots, i.e., adjusts it to DsDDFU.
[0203] It should be noted that adjusting the position of the fourth sensing time slot and / or the fourth sensing symbol is similar to adjusting the position of the third sensing time slot and / or the third sensing symbol, and will not be repeated here.
[0204] In practical applications, after being interfered with from a remote network device, the affected network device can reduce the remote interference by changing the position of the interfered sensing symbol in the time slot. However, the affected network device still needs the instruction from the interfering network device to restore the original frame structure configuration.
[0205] Based on this, in some embodiments, the method further includes:
[0206] The second network device sends a first signaling message to the first network device; wherein the first signaling message is used to indicate that the second network device is subject to remote interference;
[0207] The second network device receives a second signaling sent by the first network device; wherein the second signaling is used to indicate that the first network device can receive the first signaling;
[0208] The second network device restores its original frame structure configuration until it no longer receives the second signaling sent by the first network device.
[0209] It is understandable that after the second network device restores the original frame structure configuration, it can also instruct other network devices that cooperate with the second network device to restore the original frame structure configuration.
[0210] Understandably, if the second network device is subject to remote interference, it can change its sensing location. If there is no remote sensing interference after changing the sensing location, but communication interference exists, the initial configuration is restored as follows: Specifically, if the symbol ratio of the flexible timeslot F configuration in the frame structure configuration of the second network device includes uplink signals, then there is no need to separately configure signaling to indicate the presence / disappearance of interference. The first signal triggered by communication indicates the presence of interference, and the original frame structure configuration is restored after the interference disappears. If there is remote sensing interference after changing the sensing location, but no communication interference, the initial configuration is restored as follows: Specifically, if the symbol ratio of the flexible timeslot F configuration in the frame structure configuration of the second network device does not include uplink signals, then the second network device indicates the presence of interference through the first signaling, and the first network device replies with the second signaling until the interference disappears. At this point, the second network device no longer receives the second signaling, and the original frame structure configuration is restored.
[0211] It is understandable that, since the channel is reciprocal, the interfering network device will also be the affected network device. Therefore, the way the first network device restores the original frame structure configuration is similar to the way the second network device restores the original frame structure configuration, and will not be described in detail here.
[0212] In practical applications, after the second network device changes its sensing location as the disturbed network device, it also needs to send the adjusted frame structure configuration to the first network device so that the first network device can manage the interference.
[0213] Based on this, in some embodiments, the method further includes:
[0214] The second network device sends a third indication message to the first network device; wherein the third indication message is used to indicate the second frame structure configuration of the second network device.
[0215] In some embodiments, the second frame structure configuration of the second network device includes:
[0216] The adjusted sensing and receiving frame structure.
[0217] It is understood that after receiving the third indication information, the first network device will, based on the interference situation of the second network device indicated by the first signal and / or the number of symbols that need to be turned off, as well as the adjusted sensing and receiving frame structure of the second network device, turn off the corresponding downlink symbols to reduce remote interference to the second network device.
[0218] To implement the information transmission method of this application embodiment, this application embodiment also provides an information transmission device, which is installed in a first network device. Figure 13 This is a schematic diagram of the composition structure of the information transmission device according to an embodiment of this application, as shown below. Figure 13 As shown, the device includes:
[0219] The receiving module 131 is used to receive a first signal and a first indication information sent by the second network device; wherein, the first signal is used to indicate that the first network device interferes with the remote network device, and the first indication information is used to indicate the first frame structure configuration of the second network device.

[0228] In some embodiments, the device is further configured to:
[0229] If the first sensing time slot and / or the first sensing symbol in the frame structure configuration of the first network device are detected to be subject to remote interference, the position of the first sensing time slot and / or the first sensing symbol in the frame structure configuration of the first network device shall be adjusted.
