Description

Communication methods, communication devices, storage media and software products

[0001] This application claims priority to Chinese Patent Application No. 202411432930.4, filed on October 14, 2024, entitled "Communication Method, Communication Device, Storage Medium and Program Product", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and in particular to communication methods, communication devices, storage media, and program products. Background Technology

[0003] The adjacent channel leakage ratio (ACLR) measures the leakage of a transmitter in frequency bands outside its operating frequency band. Current protocols define ACLR metrics for terrestrial networks (TN) and non-terrestrial networks (NTN). The ACLR for TN is more stringent than that for NTN, meaning the ACLR metric for NTN is relatively lenient. This can lead to significant interference to systems in adjacent frequency bands, i.e., greater out-of-band interference, thus affecting out-of-band communication. Summary of the Invention

[0004] This application provides communication methods, communication devices, storage media, and program products in order to reduce out-of-band interference and ensure out-of-band communication.

[0005] In a first aspect, this application provides a communication method that can be executed by a terminal device. The terminal device can be the terminal itself, a component configured in the terminal (such as a processor, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the terminal functions. This application does not limit the scope of the method.

[0006] For example, receiving first configuration information, the first configuration information is used to configure a trigger event, the trigger event is used to trigger the terminal device to report out-of-band interference of at least one cell, the at least one cell being an adjacent cell of the cell where the terminal device is located; based on the first configuration information, sending interference information, the interference information is used to indicate the out-of-band interference level of the at least one cell.

[0007] In the above technical solution, the terminal device can report out-of-band interference information corresponding to adjacent cells of the cell where the terminal device is located based on configured trigger events. This allows the network device to obtain the out-of-band interference caused by the adjacent cells to the cell where the terminal device is located, thereby facilitating the reasonable adjustment of the transmitted signal strength to reduce out-of-band interference and ensure out-of-band communication. Furthermore, reporting out-of-band interference based on configured trigger events reduces overhead compared to reporting it with every measurement.

[0008] Secondly, this application provides a communication method that can be executed by a network device. The network device can be the network device itself, a component configured in the network device (such as a processor, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the functions of the network device. This application does not limit the scope of the method.

[0009] For example, first configuration information is sent, which is used to configure a trigger event, which is used to trigger the terminal device to report out-of-band interference of at least one cell, the at least one cell being an adjacent cell of the cell where the terminal device is located; interference information is received, which is used to indicate the degree of out-of-band interference of the at least one cell.

[0010] In the above technical solution, the network device can be configured to trigger an event that prompts the terminal device to report out-of-band interference from adjacent channel cells. This allows the terminal device to report interference information from adjacent channel cells based on the configuration, enabling the network device to obtain information about the out-of-band interference caused by these adjacent channel cells to the cell where the terminal device is located. This allows for the network device to adjust the strength of the transmitted signal appropriately to reduce out-of-band interference and ensure out-of-band communication. Furthermore, reporting out-of-band interference based on a configured trigger event reduces overhead compared to reporting it with every measurement.

[0011] In combination with the first and second aspects, in some possible implementations, the aforementioned triggering event includes: the out-of-band interference level of the first cell is greater than or equal to a first threshold, wherein the first cell is any one of the aforementioned at least one cell.

[0012] In other words, the aforementioned triggering events include: the out-of-band interference level of any cell being greater than or equal to a first threshold, and the terminal device reporting the interference information of that cell. Under this design, the terminal device can report interference information for cells with out-of-band interference levels greater than or equal to the first threshold, allowing the network device to obtain the out-of-band interference level of that cell. This facilitates the network device in adjusting the strength of the transmitted signal of that cell to reduce out-of-band interference and thus ensure communication. Furthermore, in the above design, the interference information indicates the out-of-band interference level of a single cell, allowing the network device to obtain the out-of-band interference level of a single cell. This makes the interference situation more targeted and accurate, thus making it easier for the network device to adjust the power of the transmitted signal.

[0013] Under the above design, the interference information includes one or more of the following: the identifier of the first cell, the out-of-band interference level of the first cell, the difference between the out-of-band interference level of the first cell and the first threshold, or the in-band signal strength of the first cell.

[0014] The identifier of the first cell can be used to identify the first cell so that the network device can identify cells with out-of-band interference levels greater than or equal to a first threshold, thereby facilitating the adjustment of the transmission signal power of the first cell to reduce out-of-band interference and ensure communication. The out-of-band interference level of the first cell, the difference between the out-of-band interference level of the first cell and the first threshold, or the in-band signal strength of the first cell can help the network device determine the degree of out-of-band interference caused by the first cell to the cell where the terminal device is located, thereby facilitating the adjustment of the transmission signal power to reduce out-of-band interference of the first cell and ensure communication.

[0015] In combination with the first and second aspects, in some possible implementations, the aforementioned triggering event includes: the sum of the out-of-band interference levels of multiple cells is greater than or equal to the second threshold, and the multiple cells belong to at least one of the aforementioned cells.

[0016] In this design, each of the aforementioned cells corresponds to a specific out-of-band interference level, and the sum of the out-of-band interference levels of all cells represents the sum of the out-of-band interference levels of each individual cell. This design facilitates the network device in obtaining the overall out-of-band interference level of the multiple cells, allowing it to adjust the strength of the transmitted signal to reduce out-of-band interference and thus ensure communication. Furthermore, this design allows the interference information to indicate the sum of the out-of-band interference levels of the multiple cells, which is more advantageous for the network device in obtaining the overall out-of-band interference level. Compared to reporting interference information when the out-of-band interference of a single cell is greater than or equal to a limit, this design provides a more lenient limit on out-of-band interference, reducing overhead.

[0017] Under this design, the interference information includes one or more of the following: the identifiers of the aforementioned cells, the sum of the out-of-band interference levels of the aforementioned cells, or the difference between the sum of the out-of-band interference levels of the aforementioned cells and the second threshold.

[0018] In this design, the interference information can also include the sum of the in-band signal strengths of multiple cells. For example, it can be in a scenario where the adjacent channel selectivity (ACS) of each cell is equal. Then, the network device can calculate the out-of-band interference level of the multiple cells based on the adjacent channel selectivity of each cell and the sum of the in-band signal strengths of the multiple cells.

[0019] The identifiers of the aforementioned cells can be used to identify which cells have an overall out-of-band interference level greater than or equal to a second threshold. This facilitates the adjustment of the transmission power of these cells to reduce out-of-band interference and ensure communication. The sum of the out-of-band interference levels of the aforementioned cells, or the difference between the sum of the out-of-band interference levels of the aforementioned cells and the second threshold, allows the network device to determine the degree of out-of-band interference caused by the aforementioned cells to the cell where the terminal device is located. This facilitates the adjustment of the transmission power of the aforementioned cells to reduce out-of-band interference and ensure communication.

[0020] In combination with the first and second aspects, in some possible implementations, the aforementioned triggering event includes: within a first duration, a first proportion is greater than or equal to a third threshold, the first proportion being the proportion of out-of-band interference level of the second cell being greater than or equal to a fourth threshold, and the second cell being any one of the aforementioned at least one cell.

[0021] In other words, within the first time period, if the proportion of out-of-band interference levels of any cell that are greater than or equal to the fourth threshold is not less than the third threshold, the terminal device reports the interference information for that cell. Under this design, the interference information can indicate the out-of-band interference level of a single cell, which is beneficial for network devices to obtain the out-of-band interference level of a single cell. The interference situation is more targeted and accurate, making it easier for network devices to adjust the transmission signal power of the cell. Furthermore, the terminal device only reports the interference information for a cell when the proportion of out-of-band interference levels of a single cell that are greater than or equal to the fourth threshold is not less than the third threshold. This means that the triggering condition for interference reporting is more stringent, and relatively speaking, the interference is moderately relaxed, which helps to reduce overhead.

[0022] Optionally, the first ratio is the ratio of the number of times the out-of-band interference level of the second cell is greater than or equal to the fourth threshold to the number of first measurements, where the number of first measurements is the number of times the terminal device measures the reference signal of the second cell; or, the first ratio is the ratio of the duration of the out-of-band interference level of the second cell being greater than or equal to the fourth threshold to the first duration.

[0023] Under the above design, the interference information includes one or more of the following: the identifier of the second cell, the first ratio, the difference between the first ratio and the third threshold, the out-of-band interference level of the second cell, the difference between the out-of-band interference level of the second cell and the fourth threshold, or the in-band signal strength of the second cell.

[0024] The identifier of the second cell can be used to identify the second cell so that the network device can identify cells whose out-of-band interference level is greater than or equal to the fourth threshold and whose proportion is not less than the third threshold. This facilitates the adjustment of the power of the transmitted signal of the second cell to reduce out-of-band interference and ensure communication. The first proportion, the difference between the first proportion and the third threshold, the out-of-band interference level of the second cell, the difference between the out-of-band interference level of the second cell and the fourth threshold, or the in-band signal strength of the second cell can help the network device determine the degree of out-of-band interference caused by the second cell to the cell where the terminal device is located. This facilitates the adjustment of the power of the transmitted signal of the second cell to reduce out-of-band interference and ensure communication.

[0025] Optionally, within the first time period, the first proportion is greater than or equal to the third threshold, including: within the first time period, the out-of-band interference level of the second cell satisfies at least one set of first measurement indicators from one or more sets of first measurement indicators, wherein each set of first measurement indicators includes a fourth threshold corresponding to the out-of-band interference level of the second cell and a third threshold corresponding to the first proportion.

[0026] In other words, the network device can be configured with a first set of measurement indicators, which includes a fourth threshold corresponding to the out-of-band interference level and a third threshold corresponding to a first proportion. Within a first time period, if the proportion of any cell whose out-of-band interference level is greater than or equal to the fourth threshold is not less than the third threshold, the terminal device reports the interference information of that cell. The network device can also be configured with multiple sets of first measurement indicators, each set including a fourth threshold corresponding to the out-of-band interference level and a third threshold corresponding to a first proportion. If the out-of-band interference level of any cell within the first time period satisfies at least one set of the multiple first measurement indicators, the terminal device reports the interference information of that cell. When the network device is configured with multiple sets of first measurement indicators, the larger the fourth threshold in each set, the smaller the third threshold can be. This helps the network device determine the out-of-band interference situation of cells with high out-of-band interference levels.

[0027] Optionally, the aforementioned interference information is also used to indicate the index of at least one set of first measurement indicators.

[0028] By reporting at least one set of indexes for the first measurement indicators, the network device can determine the first measurement indicators on which the terminal device is based.

[0029] In combination with the first and second aspects, in some possible implementations, the aforementioned triggering event includes: within a first duration, a second proportion is greater than or equal to a fifth threshold, whereby the sum of the out-of-band interference levels of the aforementioned multiple cells is greater than or equal to a sixth threshold.

[0030] This design allows network devices to obtain the overall out-of-band interference level of multiple cells, facilitating the adjustment of the transmitted signal strength of these cells to reduce out-of-band interference and thus ensure communication. Furthermore, the terminal device only reports interference information for these cells when the sum of their out-of-band interference levels is greater than or equal to the sixth threshold and not less than the fifth threshold. In other words, the triggering condition for interference reporting is more stringent, while relatively relaxing interference restrictions, which helps reduce overhead.

[0031] Optionally, the second ratio is the ratio of the number of times the sum of the out-of-band interference levels of the aforementioned multiple cells is greater than or equal to the sixth threshold to the number of second measurements, where the number of second measurements is the number of times the terminal device measures the reference signal of the aforementioned multiple cells; or, the second ratio is the ratio of the duration during which the sum of the out-of-band interference levels of the aforementioned multiple cells is greater than or equal to the sixth threshold to the first duration.

[0032] Under the above design, the interference information includes one or more of the following: the identifiers of the above-mentioned multiple cells, the second ratio, the difference between the second ratio and the fifth threshold, the sum of the out-of-band interference levels of the above-mentioned multiple cells, or the difference between the sum of the out-of-band interference levels of the above-mentioned multiple cells and the sixth threshold.

[0033] The identifiers of the aforementioned multiple cells can be used to identify the multiple cells so that the network device can identify which cells have a ratio where the sum of their out-of-band interference levels is greater than or equal to the sixth threshold and not less than the fifth threshold. This facilitates the adjustment of the transmission power of the aforementioned multiple cells to reduce out-of-band interference and ensure communication. The aforementioned second ratio, the difference between the second ratio and the fifth threshold, the sum of the out-of-band interference levels of the aforementioned multiple cells, or the difference between the sum of the out-of-band interference levels of the aforementioned multiple cells and the sixth threshold can facilitate the network device in determining the degree of out-of-band interference caused by the aforementioned multiple cells to the cell where the terminal device is located. This facilitates the adjustment of the transmission power of the aforementioned multiple cells to reduce out-of-band interference and ensure communication.

[0034] Optionally, within the first time period, the second proportion is greater than or equal to the fifth threshold, including: within the first time period, the sum of the out-of-band interference levels of the aforementioned multiple cells satisfies at least one set of second measurement indicators in one or more sets of second measurement indicators, wherein each set of second measurement indicators includes a sixth threshold corresponding to the sum of the out-of-band interference levels of the aforementioned multiple cells and a fifth threshold corresponding to the second proportion.

[0035] In other words, the network device can be configured with a second set of measurement indicators, which includes a sixth threshold corresponding to the sum of out-of-band interference levels and a fifth threshold corresponding to a second ratio. Within a first time period, if the proportion of the sum of out-of-band interference levels of the aforementioned cells that is greater than or equal to the sixth threshold is not less than the fifth threshold, the terminal device reports the interference information of the aforementioned cells. The network device can also be configured with multiple sets of second measurement indicators, each set including a sixth threshold corresponding to the sum of out-of-band interference levels and a fifth threshold corresponding to a second ratio. If the sum of out-of-band interference levels of the aforementioned cells satisfies at least one of the multiple sets of second measurement indicators within the first time period, the terminal device reports the interference information of those cells. When the network device is configured with multiple sets of second measurement indicators, the larger the sixth threshold in each set, the smaller the fifth threshold can be. This helps the network device determine the out-of-band interference situation of cells with a large sum of out-of-band interference levels.

[0036] Optionally, the aforementioned interference information is also used to indicate the index of at least one set of second measurement indicators.

[0037] In combination with the first and second aspects, in some possible implementations, the first duration is predefined; or, the first duration is configured by the network device.

[0038] For example, the network device sends second configuration information, which is used to configure the first duration. Correspondingly, the terminal device receives the second configuration information. The second configuration information and the first configuration information may be carried in the same signaling or in different signaling; this application does not limit this.

[0039] Thirdly, this application provides a communication device capable of implementing the method described in the first aspect and any possible implementation thereof, or implementing the method described in the second aspect and any possible implementation thereof. The device includes corresponding modules for performing the above-described methods. The modules included in the device can be implemented in software and / or hardware.

[0041] Optionally, the device further includes a communication interface, to which the at least one processor is coupled. The communication interface is used to receive signals from other communication devices outside the device and transmit them to the at least one processor, or to send signals from the at least one processor to other communication devices outside the device. Exemplarily, the communication interface may be a transceiver, circuit, bus, module, pin, or other type of communication interface.

[0042] Optionally, the device further includes a memory for storing program instructions and data. The memory is coupled to at least one processor, which, when executing the instructions stored in the memory, can implement the methods described in the preceding aspects.

[0043] Fifthly, this application provides a computer-readable storage medium storing a computer program or instructions that, when executed, implement the method described in the first aspect and any possible implementation thereof, or implement the method described in the second aspect and any possible implementation thereof.

[0044] Sixthly, this application provides a computer program product including instructions that, when executed, implement the method described in the first aspect and any possible implementation thereof, or implement the method described in the second aspect and any possible implementation thereof.

[0045] In a seventh aspect, this application provides a chip system including at least one processor for supporting the implementation of the functions involved in the first aspect and any possible implementation of the first aspect, or for supporting the implementation of the functions involved in the second aspect and any possible implementation of the second aspect, such as receiving or processing data involved in the above methods.

[0046] In one possible design, the chip system also includes a memory for storing program instructions and data, which may be located within or outside the processor.

[0047] In one possible design, the chip system further includes an interface circuit and / or a power supply circuit, wherein the interface circuit is used to transmit data and the power supply circuit is used to supply power to the chip system.

[0048] The chip system can consist of chips or include chips and other discrete components.

[0070] Ninth, in the embodiments of this application, the terminal and / or network device may execute some or all of the steps in each embodiment. These steps or operations are merely examples, and the embodiments of this application may also perform other operations or variations of various operations. Furthermore, the steps may be executed in different orders as presented in each embodiment, and it is not necessary to execute all the operations in the embodiments of this application. Moreover, the sequence number of each step does not imply the order of execution; the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0071] To better understand the methods provided in the embodiments of this application, the terms involved in this application will be explained in detail below.

[0072] 1. NTN Communication: Compared to terrestrial communication, NTN communication offers advantages such as wider coverage and more flexible networking. NTN communication utilizes devices like drones, high-altitude platform stations (HAPS), and satellites to provide data transmission and voice communication services to terminals. HAPS equipment typically operates at altitudes of 8–50 kilometers above the ground. Based on satellite orbital altitude, satellite communication systems can be categorized into three types: geostationary earth orbit (GEO) satellite communication systems (also known as synchronous orbit satellite systems); medium earth orbit (MEO) satellite communication systems; and low earth orbit (LEO) satellite communication systems. GEO satellites orbit at an altitude of 35,786 km. The advantage of GEO satellite communication is its ability to remain relatively stationary relative to the ground and provide a large coverage area. MEO satellites orbit at altitudes between 2,000 km and 35,786 km. The advantage of MEO satellite communication is that it can achieve global coverage with a relatively small number of satellites. MEO satellites are primarily used for positioning and navigation. LEO satellites orbit at altitudes ranging from 300km to 2000km. Compared to MEO and GEO satellites, LEO satellites orbit at lower altitudes, offering advantages such as lower data propagation latency, less transmission loss, and relatively lower launch costs. Therefore, LEO satellite communication has gained widespread attention in recent years.

[0073] Depending on the payload type, NTN networks include two network architectures: regenerative architecture and transparent architecture. The following will explain these network architectures with reference to Figures 1 and 2.

[0074] Figure 1 is a schematic diagram of a network architecture for NTN communication provided in an embodiment of this application.

[0075] As shown in Figure 1, during communication between the terminal and the base station, the satellite communicates with the gateway station (also known as a gateway) via the Uu interface, the base station communicates with the 5th-generation core network (CN) via the next-generation (NG) interface, and the CN communicates with the data network via the N6 interface. The network communication segment between the terminal and the base station is called the remote radio unit (RF unit), and the radio access network (RAN) node ensures normal communication between the terminal and the CN. In the network architecture shown in Figure 1, the satellite can operate in transparent mode, for example. In this mode, the satellite can act as a relay for RF filtering, frequency conversion, and amplification, regenerating the physical layer signal so that it is invisible to the protocol layers above the physical layer. The gateway station has the functions of a base station or some of the functions of a base station; in this case, the gateway station can be considered as a base station. Alternatively, the base station and the gateway station can be deployed separately. In this case, the delay of the feeder link includes both the delay from the satellite to the gateway station and the delay from the gateway station to the base station.

[0076] Figure 2 is a schematic diagram of another network architecture for NTN communication provided in an embodiment of this application.

[0077] As shown in Figure 2, in this network architecture, for example, the satellite can operate in regenerative mode. In this mode, the satellite has data processing capabilities and functions as a base station or partially as one. The satellite can be considered a base station, or a base station can be deployed on the satellite, or the functions of a base station or partially integrated on the satellite. The satellite can communicate with the terminal via the Uu interface, and with the CN via the NG interface. The CN communicates with the data network via the N6 interface. During the communication between the satellite and the CN, the gateway station connects network segments using different protocols to ensure normal communication. In the satellite-gateway station network segment, the NG interface is the NG interface deployed in the satellite radio interface (SRI). The RAN node ensures normal communication between the terminal and the CN.

[0078] Optionally, in the network architecture shown in Figure 1 or Figure 2, the satellite can be a GEO satellite, a MEO satellite, or a LEO satellite. The satellite can also be replaced by other NTN devices such as HAPS devices or drones. This application does not limit the type of satellite.

[0079] The network architecture for the convergence of TN and NTN will be described below with reference to Figures 3 and 4. In the network architecture shown in Figure 3, the NTN devices operate in transparent mode, while in the network architecture shown in Figure 4, the NTN devices operate in regenerative mode. In the network architectures shown in Figures 3 and 4, the NTN devices are exemplified by GEO satellites, LEO satellites, HAPS devices, or UAVs, but this application does not limit the type of these devices.

[0080] Figure 3 is a schematic diagram of a network architecture for the convergence of NTN and TN provided in an embodiment of this application.

[0081] As shown in Figure 3, base stations in the TN (referred to as terrestrial base stations in Figure 3) and base stations in the NTN (referred to as satellite base stations to distinguish them from TN base stations) can communicate with each other through a common core network, or through interfaces defined between base stations to achieve more timely assistance and interconnection. NTN equipment (GEO satellites, LEO satellites, and UAVs in Figure 3) can communicate with gateway stations via the Uu interface, while NTN base stations can communicate with the core network via the NG interface. Satellite base stations can, for example, be deployed on the ground. The link between NTN equipment and terminals is called a service link, and the link between satellites and gateway stations is called a feeder link.

[0082] Figure 4 is a schematic diagram of another network architecture for the convergence of NTN and TN provided in an embodiment of this application.

[0083] As shown in Figure 4, unlike Figure 3, the base stations in NTN are deployed on NTN equipment (called airborne base stations). In other words, NTN equipment has data processing capabilities and functions as a base station or some of the functions of a base station. In this case, NTN equipment can be regarded as a base station. Base stations in TN and NTN can be interconnected and communicate with each other through a common core network, or through interfaces defined between base stations to achieve more timely assistance and interconnection.

[0084] 2. Cell coverage in TN and NTN communications: Different communication technologies and application scenarios can affect the characteristics of cell coverage. In TN communications (such as cellular networks), cell coverage is typically provided by terrestrial base stations, and its range and characteristics are influenced by factors such as base station location and density, antenna type and configuration, and the frequency band used. In NTN communications, cell coverage is provided by non-terrestrial nodes such as satellites, drones, and high-altitude platforms. While the coverage is extensive, it is affected by factors such as orbital altitude, flight altitude, beamforming, and multi-beam technology.

[0085] Figure 5 is a schematic diagram of cell coverage in cellular and satellite communications provided in an embodiment of this application.

[0086] As shown in Figure 5a), in cellular communication, cell coverage is provided by ground base stations. A cell can be displayed as multiple hexagonal or circular areas, each representing a cell. Cells may overlap to ensure seamless coverage and handover. As shown in Figure 5b), satellite cell coverage is provided by satellites and can be displayed as elliptical or circular areas, covering a specific area of ​​the Earth's surface.

[0087] 3. ACLR: This measure can be used to assess the leakage of a transmitter in frequency bands outside its operating frequency band. For a given cell (e.g., cell 1), interference to cell 1 may occur due to leakage from a neighboring cell (e.g., cell 2) in a frequency band outside its operating frequency band. This interference can also be referred to as out-of-band interference for cell 2. The following section will explain out-of-band interference in cellular cells (i.e., cells in cellular communication) and satellite cells (i.e., cells in satellite communication) in detail.

[0088] I. Out-of-band interference in cellular cells

[0089] Assuming that in cellular communication, the ACLR is 45dB, the signal-to-noise ratio (SNR) at the center of the cell is 30dB, and the SNR at the cell edge is approximately 0dB due to increased transmission loss, and the out-of-band interference is characterized by interference (I) / noise (N) as an example, the specific analysis of out-of-band interference is as follows:

[0090] (1) At the center of the cell, the leakage intensity is: I / N = 30dB (SNR) – 45dB (ACLR) = –15dB; coverage multiple: 1; total leakage: total I / N = I / N + 10log10 (coverage multiple, if the value is 1) + 10log10 (number of adjacent bands, if the value is 2) = –12dB. It can be understood that the leakage intensity of this cell can also be interpreted as the degree of out-of-band interference of this cell to adjacent frequency cells.

[0091] (2) Cell edge: Leakage intensity: I / N=0dB(SNR)–45dB(ACLR)=–45dB; Coverage layer: 3 layers; Total leakage: Total I / N=I / N+10log10(3)+10log10(2)=–37dB.

[0092] Assuming an ACLR of 24dB and an SNR of 20dB in LEO communication, at the beam edge, due to a 3dB drop in antenna gain, the SNR is approximately 17dB. The specific analysis of out-of-band interference is as follows:

[0093] (1) Satellite cell center: Leakage intensity: I / N = 20dB(SNR) – 24dB(ACLR) = –4dB; Coverage weight: 1; Total leakage: Total I / N = I / N + 10log10(1) + 10log10(2) = –1dB.

[0094] (2) Satellite cell edge: Leakage intensity: I / N=17dB(SNR)–24dB(ACLR)=–7dB; Coverage layer: 3 layers; Total leakage: Total I / N=I / N+10log10(3)+10log10(2)=0.8dB.

[0095] According to the current Federal Communications Commission (FCC) spurious and conducted emissions standards (FCC SCS), the out-of-band emission (OOBE) standard for LEO satellites is –120 dBW / m². 2 Taking / MHz as an example, the out-of-band interference of a satellite cell is analyzed in detail as follows:

[0096] (1) Satellite cell center: Leakage intensity: I / N = –5.3dB (corresponding to the center frequency of 2 GHz); Coverage multiple: 1; Total leakage: Total I / N = I / N + 10log10(1) + 10log10(2) = –2.3dB.

[0097] (2) Satellite cell edge: leakage intensity: I / N = –8.3dB; coverage layer: 3 layers; total leakage: total I / N = I / N + 10log10(3) + 10log10(2) = –0.5dB.

[0098] The examples above demonstrate that ACLR in TN is more stringent than ACLR in NTN. The current protocol defines ACLR metrics for both TN and NTN. Table 1 provides examples of ACLR metrics for TN, and Table 2 provides examples of ACLR metrics for NTN. A more detailed explanation of ACLR metrics can be found in existing protocols and will not be elaborated upon here.

[0099] Table 1

[0100] Table 2

[0101] As shown in Table 1, the ACLR index in TN is 45dB, and as shown in Table 2, the ACLR index in LEO is 24dB.

[0102] It can be seen that the ACLR metric in NTN is relatively lenient, which may cause significant interference to systems in adjacent frequency bands, i.e., significant out-of-band interference, thus affecting out-of-band communication.

[0103] To address this, this application provides a communication method in which a network device can be configured to trigger an event that prompts a terminal device to report out-of-band interference from adjacent channel cells. This allows the terminal device to report out-of-band interference information from adjacent channel cells based on the configuration, enabling the network device to assess the extent of out-of-band interference caused by the adjacent channel cells to the cell where the terminal device is located. This allows the network device to adjust the strength of the transmitted signal accordingly, reducing out-of-band interference and thus ensuring out-of-band communication. Furthermore, reporting out-of-band interference based on a configured trigger event reduces overhead compared to reporting it with every measurement.

[0104] The communication method provided in this application will now be described in detail with reference to the accompanying drawings.

[0105] The method provided in this application can be applied to the NTN shown in Figure 1 or Figure 2, or to the network where NTN and TN are integrated as shown in Figure 3 or Figure 4, or to other networks. This application does not limit the application to these applications.

[0106] The following describes in detail the methods provided in the embodiments of this application, using terminals or network devices as the execution subjects (a network device is an example of a network apparatus, and a terminal is an example of a terminal apparatus). The specific forms and quantities of the devices shown are merely examples and should not constitute any limitation on the implementation of the methods provided in this application. In the embodiments shown below, the terminal can also be replaced by components configured in the terminal (such as chips, chip systems, processors, etc.), or by logic modules or software capable of implementing all or part of the functions of the terminal. Similarly, the network device can also be replaced by components configured in the network device (such as chips, chip systems, processors, etc.), or by logic modules or software capable of implementing all or part of the functions of the network device. The aforementioned network device can, for example, be a base station in NTN communication within the network architecture shown in Figures 1 to 4. The base station can be deployed on the ground or on a satellite; this application does not limit its deployment in this regard.

[0107] It should be noted that in a transparent architecture, information sent by network devices can be forwarded by NTN devices (such as satellites).

[0108] Figure 6 is a schematic flowchart of the communication method 600 provided in an embodiment of this application.

[0109] The method 600 shown in Figure 6 includes steps 610 and 620. The steps in method 600 are described in detail below.

[0110] In step 610, the network device sends first configuration information, which is used to configure a trigger event. This trigger event is used to trigger the terminal to report out-of-band interference from at least one cell. Accordingly, the terminal receives the aforementioned first configuration information.

[0111] Wherein, at least one of the aforementioned cells is an adjacent-frequency cell of the cell where the terminal is located. An adjacent-frequency cell can be understood as a cell with adjacent frequency points / bands. Out-of-band interference of any of the aforementioned at least one cell refers to interference caused by a signal outside the frequency band occupied by that cell to the cell where the terminal is located. For example, if the cell where the terminal is located is cell 1, and cell 2 is one of the aforementioned at least one cells, then out-of-band interference of cell 2 refers to interference caused by a signal outside the frequency band occupied by cell 2 to cell 1.

[0112] The aforementioned first configuration information is used to configure trigger events. This first configuration information (or trigger event configuration) includes, for example, trigger conditions, that is, the conditions that must be met for the terminal to report out-of-band interference from adjacent cells, or under what conditions the terminal reports out-of-band interference from adjacent cells. The trigger event configuration may also include, for example, a measurement period, a reporting period, a maximum report count, etc., which are not limited in this application. The measurement period can be used to define the time interval for the terminal to perform measurements. The reporting period can be used to define the time interval for the terminal to report out-of-band interference. The maximum report count can be used to limit the number of times the terminal reports out-of-band interference within a specific time period to reduce overhead.

[0113] For example, the network device sends first configuration information, which is used to configure a trigger event, such as one or more of trigger conditions, measurement period, reporting period, and maximum reporting number, to trigger the terminal to report out-of-band interference from at least one cell. Accordingly, the terminal receives the aforementioned first configuration information.

[0114] In this application, the cell can be replaced by the bandwidth part (BWP) or the carrier, and this application does not limit it.

[0115] In step 620, the terminal sends interference information based on the first configuration information, which indicates the out-of-band interference level of the at least one cell. Correspondingly, the network device receives the interference information.

[0116] The aforementioned transmission of interference information based on the first configuration information can be understood as transmitting interference information when the out-of-band interference of at least one cell meets the aforementioned triggering conditions. Transmitting interference information when the out-of-band interference of at least one cell meets the aforementioned triggering conditions can be based on reporting interference information according to the aforementioned reporting period, or it can be reported as soon as the triggering conditions are met; this application does not limit this.

[0117] The aforementioned interference information is used to indicate the out-of-band interference level of at least one cell. The out-of-band interference level can be characterized, for example, by the I / N ratio. I / N can satisfy: I / N = In-band signal strength – Adjacent channel suppression, where adjacent channel suppression can be considered a generalized ACLR. In other words, I / N can also satisfy: I / N = In-band signal strength – ACLR. The aforementioned in-band signal strength can be characterized, for example, by SNR, received signal strength indicator (RSSI), reference signal received power (RSRP), reference signal receiving quality (RSRQ), or signal-to-interference-plus-noise ratio (SINR), etc., and this application does not limit this to any particular value.

[0118] It should be understood that the embodiments described below use I / N as an example to illustrate the level of out-of-band interference, but this should not be construed as limiting this application in any way. For example, the level of out-of-band interference can also be characterized by other parameters, and this application does not limit this. When the terminal reports the in-band signal strength of at least one of the above-mentioned cells, the network device can determine the level of out-of-band interference based on the in-band signal strength and adjacent channel suppression.

[0119] In the above technical solution, the network device can be configured to trigger an event that prompts the terminal to report out-of-band interference from adjacent cells. This allows the terminal to report interference information from adjacent cells based on the configuration, enabling the network device to obtain information about the out-of-band interference caused by these adjacent cells to the terminal's local cell. This allows for the appropriate adjustment of the transmitted signal strength to reduce out-of-band interference and ensure out-of-band communication. Furthermore, reporting out-of-band interference based on a configured trigger event reduces overhead compared to reporting it with every measurement.

[0120] Optionally, before the terminal sends interference information, the network device may also send third configuration information, which is used to configure reference signal and / or spectrum template (mask) information.

[0121] The aforementioned reference signal can be used to measure the in-band signal strength of adjacent cells in the cell where the terminal is located, so that the terminal can calculate the out-of-band interference level. The aforementioned spectrum template information can be used to determine ACLR or adjacent channel suppression, where ACLR needs to satisfy the spectrum template.

[0122] For example, the network device sends third configuration information, which can be used to configure the reference signals (such as pilots) and spectrum template information of one or more adjacent cells (adjacent cells of the cell where the terminal is located). Accordingly, the terminal receives the aforementioned third configuration information. The terminal measures the reference signals of the one or more adjacent cells to obtain the in-band signal strength of the one or more adjacent cells, and calculates the out-of-band interference level (such as I / N) of the one or more adjacent cells.

[0123] It is understandable that after the terminal determines the out-of-band interference level of one or more adjacent cells, it can report the interference information of at least one of the one or more adjacent cells based on the aforementioned triggering event.

[0124] The following section will detail the possible designs for triggering events and the corresponding interference information.

[0125] Design 1: The triggering events mentioned above include: the out-of-band interference level of the first cell is greater than or equal to the first threshold, and the first cell is any one of the above at least one cells.

[0126] In other words, when the out-of-band interference level of any cell is greater than or equal to the first threshold, the terminal reports the interference information of that cell.

[0127] For example, the terminal determines the out-of-band interference level of one or more adjacent frequency cells in the cell where the terminal is located, and reports the interference information of cells among the one or more adjacent frequency cells whose out-of-band interference level is greater than or equal to a first threshold. For example, if the out-of-band interference level of cell 1 among the one or more adjacent frequency cells is greater than the first threshold, the terminal reports the interference information of cell 1 to indicate the out-of-band interference level of cell 1. As another example, if the out-of-band interference level of cell 1 among the one or more adjacent frequency cells is greater than the first threshold, and the out-of-band interference level of cell 2 is also greater than the first threshold, the terminal reports the interference information to indicate the out-of-band interference levels of cell 1 and cell 2.

[0128] The aforementioned triggering events use the out-of-band interference level of a single cell as the granularity. Similarly, when the terminal reports interference information, it also uses the out-of-band interference level of a single cell as the granularity. In this way, network devices can obtain the out-of-band interference level of a single cell, making the interference situation more targeted and accurate, and thus making it easier for network devices to adjust the transmission signal power of a single cell.

[0129] Optionally, in the design, the interference information may include one or more of the following: the identifier of the first cell, the out-of-band interference level of the first cell, the difference between the out-of-band interference level of the first cell and a first threshold, or the in-band signal strength of the first cell.

[0130] When a terminal reports the in-band signal strength of a first cell, the network device can determine the out-of-band interference level of the first cell based on the in-band signal strength and the adjacent channel suppression corresponding to that first cell. For example, the out-of-band interference level is calculated as: Out-of-band interference level = In-band signal strength – Adjacent channel suppression. It should be understood that the calculation formula for the out-of-band interference level involved in this application is merely an example and should not constitute any limitation on this application.

[0131] For example, the out-of-band interference level is characterized by I / N. Accordingly, the first threshold is the threshold corresponding to the I / N of a single cell (such as threshold 1). Taking the I / N of cell 1 being greater than threshold 1 as an example, the terminal can report one or more of the following: the identifier of cell 1, the I / N of cell 1, the difference between the I / N of cell 1 and threshold 1, or the in-band signal strength of cell 1.

[0132] Design 2: The triggering events mentioned above include: the sum of the out-of-band interference levels of multiple cells is greater than or equal to the second threshold, and these multiple cells belong to at least one of the aforementioned cells.

[0133] In other words, one of the aforementioned cells can correspond to a certain level of out-of-band interference. When the cumulative value of the out-of-band interference levels of each of the aforementioned cells is greater than or equal to the second threshold, the terminal reports interference information to indicate the sum of the out-of-band interference levels of the aforementioned cells.

[0134] For example, the terminal determines the out-of-band interference level of each of the multiple adjacent frequency cells in the cell where the terminal is located. When the sum of the out-of-band interference levels of the multiple adjacent frequency cells is greater than or equal to a second threshold, the terminal reports interference information to indicate the sum of the out-of-band interference levels of the multiple adjacent frequency cells. For example, if the multiple adjacent frequency cells include cell 1, cell 2, and cell 3, when the cumulative value (= out-of-band interference level of cell 1 + out-of-band interference level of cell 2 + out-of-band interference level of cell 3) is greater than or equal to the second threshold, the terminal reports interference information to indicate the cumulative value. As another example, if the adjacent frequency cells of the cell where the terminal is located include cells 1 to 5, and the sum of the out-of-band interference levels of cells 1 to 3 is greater than or equal to the second threshold, then the terminal reports interference information to indicate the sum of the out-of-band interference levels of cells 1 to 3.

[0135] This design facilitates network devices in obtaining the overall out-of-band interference level of the aforementioned multiple cells. This allows network devices to adjust the strength of their transmitted signals to reduce out-of-band interference and thus ensure communication. Furthermore, this design indicates the sum of the out-of-band interference levels of the multiple cells, which is beneficial for network devices to obtain the overall out-of-band interference level. Compared to reporting interference information when the out-of-band interference of a single cell is greater than or equal to a limit, this design provides a more lenient limit on out-of-band interference, reducing overhead.

[0136] Optionally, under Design 2, the interference information includes one or more of the following: the identifiers of the aforementioned multiple cells, the sum of the out-of-band interference levels of the aforementioned multiple cells, or the difference between the sum of the out-of-band interference levels of the aforementioned multiple cells and the second threshold.

[0137] In this design, the interference information can also include the sum of the in-band signal strengths of multiple cells. For example, in a scenario where the adjacent channel suppression of each cell is equal, the network device can calculate the sum of the out-of-band interference levels of the multiple cells based on the adjacent channel suppression of each cell and the sum of the in-band signal strengths of the multiple cells. For example, the sum of the out-of-band interference levels of the multiple cells = the sum of the in-band signal strengths of the multiple cells – the number of the multiple cells * the adjacent channel suppression of a single cell.

[0138] In Design 2, an example of the above interference information is to take the out-of-band interference level as represented by I / N. Accordingly, the second threshold is the threshold corresponding to the sum of the I / N of the above multiple cells (such as threshold 2). Taking the sum of the out-of-band interference levels of cell 1, cell 2 and cell 3 as an example, which is greater than threshold 2, the terminal can report one or more of the following: the identifiers of the above three cells, the sum of the I / N of the above three cells, or the difference between the sum of the I / N of the above three cells and threshold 2.

[0139] Design 3: The above-mentioned triggering events include: within a first duration, a first proportion is greater than or equal to a third threshold, the first proportion is the proportion of the out-of-band interference level of the second cell being greater than or equal to a fourth threshold, and the second cell is any one of the above-mentioned cells.

[0140] In other words, within the first time period, if the proportion of out-of-band interference levels of any cell that are greater than or equal to the fourth threshold is not less than the third threshold, the terminal reports the interference information of the aforementioned cell to indicate the out-of-band interference level of that cell.

[0141] In one example, the terminal determines the out-of-band interference (OI) level of each of one or more adjacent cells within its own cell during a first time period, and reports the interference information of cells whose OI level is greater than or equal to a fourth threshold and whose proportion within the first time period is not less than a third threshold. For instance, if the proportion of cell 1 with OI greater than or equal to the fourth threshold within the first time period is not less than the third threshold, the terminal reports the interference information for cell 1 to indicate its OI level. As another example, if the proportion of cell 1 with OI greater than or equal to the fourth threshold within the first time period is not less than the third threshold, and the proportion of cell 2 with OI greater than or equal to the fourth threshold within the first time period is also not less than the third threshold, the terminal reports the interference information to indicate the OI levels of cell 1 and cell 2 within the first time period.

[0142] Under design three, the aforementioned interference information can indicate the out-of-band interference level of a single cell, which is beneficial for network devices to obtain the out-of-band interference level of a single cell. The interference situation is more targeted and accurate, making it easier for network devices to adjust the transmission signal power of the aforementioned cell. In addition, the terminal only reports the interference information of a cell when the proportion of out-of-band interference levels of a single cell that are greater than or equal to the fourth threshold is not less than the third threshold. In other words, the triggering condition for interference reporting is more stringent, and relatively speaking, the interference is moderately relaxed, which helps to reduce overhead.

[0143] Optionally, the first ratio is the ratio of the number of times the out-of-band interference level of the second cell is greater than or equal to the fourth threshold to the number of first measurements, where the number of first measurements is the number of times the terminal measures the reference signal of the second cell; or, the first ratio is the ratio of the duration of the out-of-band interference level of the second cell being greater than or equal to the fourth threshold to the first duration.

[0144] For example, within the first time period, the terminal measures the reference signal of the second cell 10 times. Each measurement can calculate the corresponding out-of-band interference level. If the number of times the out-of-band interference level of the second cell is greater than or equal to the fourth threshold is 3, then the first proportion is 30%.

[0145] Another example, taking a first duration of 10 seconds as an example, if the out-of-band interference level of the second cell is greater than or equal to the fourth threshold for 5 seconds within those 10 seconds, then the first proportion is 50%.

[0146] Optionally, under Design 3, the interference information includes one or more of the following: the identifier of the second cell, the first ratio, the difference between the first ratio and the third threshold, the out-of-band interference level of the second cell, the difference between the out-of-band interference level of the second cell and the fourth threshold, or the in-band signal strength of the second cell.

[0147] When a terminal reports the in-band signal strength of the second cell, the network device can determine the out-of-band interference level of the second cell based on the in-band signal strength of the second cell and the adjacent channel suppression corresponding to the first cell.

[0148] For example, the out-of-band interference level is characterized by I / N. Correspondingly, the fourth threshold is the threshold corresponding to the I / N of a single cell within the first time period (e.g., threshold 4), and the third threshold is the threshold corresponding to the proportion of a single cell whose I / N is greater than or equal to threshold 4 within the first time period (e.g., threshold 3). Taking the proportion of cell 1 whose I / N is greater than or equal to threshold 4 within the first time period (denoted as proportion 1) as not less than threshold 3 as an example, the terminal can report one or more of the following: the identifier of cell 1, proportion 1, the difference between proportion 1 and threshold 3, the I / N of cell 1, the difference between the I / N of cell 1 and threshold 4, or the in-band signal strength of cell 1. Among them, the I / N of cell 1 can be the I / N when the I / N of cell 1 within the first time period is greater than or equal to threshold 4, and the I / N of cell 1 can be one or more. Similarly, the difference between the I / N of cell 1 and threshold 4 can also be one or more.

[0149] Optionally, within the first time period, the first proportion is greater than or equal to the third threshold, including: within the first time period, the out-of-band interference level of the second cell satisfies at least one set of first measurement indicators from one or more sets of first measurement indicators, wherein each set of first measurement indicators includes a fourth threshold corresponding to the out-of-band interference level of the second cell and a third threshold corresponding to the first proportion.

[0150] In other words, the network device can be configured with a first set of measurement indicators, which includes a fourth threshold corresponding to the out-of-band interference level and a third threshold corresponding to a first proportion. If the proportion of any cell whose out-of-band interference level is greater than or equal to the fourth threshold is not less than the third threshold, the terminal reports the interference information of that cell. The network device can also be configured with multiple sets of first measurement indicators, each set including a fourth threshold corresponding to the out-of-band interference level and a third threshold corresponding to a first proportion. If the out-of-band interference level of any cell satisfies at least one set of the multiple sets of first measurement indicators within a first time period, the terminal reports the interference information of that cell. When the network device is configured with multiple sets of first measurement indicators, the larger the fourth threshold in each set, the smaller the third threshold can be. This helps the network device determine the out-of-band interference situation of cells with high out-of-band interference levels.

[0151] Taking out-of-band interference level characterized by I / N as an example, one possible design for the above-mentioned multiple sets of first measurement indicators is as follows: Measurement indicator 1: The proportion of a single cell with an I / N greater than or equal to a1dB is not less than b1%; Measurement indicator 2: The proportion of a single cell with an I / N greater than or equal to a2dB is not less than b2%; Measurement indicator 3: The proportion of a single cell with an I / N greater than or equal to a3dB is not less than b3%; ... The first duration is, for example, 10 seconds.

[0152] In this application, "greater than or equal to" and "not less than" have the same meaning and can be substituted. Alternatively, "greater than or equal to" can also be replaced with "greater than" or "exceeds".

[0153] Another possible design is that the aforementioned multiple sets of first measurement indicators include: b1% of individual cells with an I / N greater than or equal to a1dB; measurement indicator 2: b2% of individual cells with an I / N greater than or equal to a2dB; measurement indicator 3: b3% of individual cells with an I / N greater than or equal to a3dB; ... where the first duration is, for example, 10 seconds.

[0154] Optionally, the aforementioned interference information is also used to indicate the index of at least one set of first measurement indicators.

[0155] For example, the aforementioned multiple sets of first measurement indicators include: Measurement indicator 1: the proportion of a single cell whose I / N is greater than or equal to a1dB is not less than b1%; Measurement indicator 2: the proportion of a single cell whose I / N is greater than or equal to a2dB is not less than b2%; Measurement indicator 3: the proportion of a single cell whose I / N is greater than or equal to a3dB is not less than b3%; ... For example, a1 > a2 > a3, b1 < b2 < b3. The terminal determines the I / N of one or more adjacent cells of the cell where the terminal is located within a first time period. Assuming that within the first time period, the proportion of I / N of cell 1 greater than or equal to a1 exceeds b1, the terminal reports interference information for cell 1. This interference information includes one or more of the following: the identifier of cell 1, the proportion of I / N of cell 1 greater than or equal to a1, the difference between the proportion of I / N of cell 1 greater than or equal to a1 and b1, the I / N of cell 1 (which can be the I / N when I / N is greater than or equal to a1 in multiple measurements within the first time period), the difference between the I / N of cell 1 and a1, the in-band signal strength of cell 1, or the index of measurement indicator 1 (to identify the measurement indicator). By reporting the index of at least one set of the above-mentioned first measurement indicators, the network device can easily determine which set of first measurement indicators the terminal uses to determine whether the adjacent cell meets the triggering condition.

[0156] Design 4: The above-mentioned triggering events include: within the first duration, the second proportion is greater than or equal to the fifth threshold, and the second proportion is the proportion in which the sum of the out-of-band interference levels of the above multiple cells is greater than or equal to the sixth threshold.

[0157] In other words, if the cumulative value of out-of-band interference of the above-mentioned multiple cells is greater than or equal to the sixth threshold and the proportion is not less than the fifth threshold, the terminal will report the interference information of the above-mentioned multiple cells.

[0158] For example, the terminal determines the out-of-band interference level of each of the multiple adjacent cells in the cell where the terminal is located within a first time period. When the proportion of the sum of the out-of-band interference levels of the multiple adjacent cells within the first time period that is greater than or equal to a sixth threshold is not less than a fifth threshold, the terminal reports interference information to indicate the sum of the out-of-band interference levels of the multiple adjacent cells within the first time period. For example, the multiple adjacent cells include cell 1, cell 2, and cell 3. When the cumulative value (= out-of-band interference level of cell 1 + out-of-band interference level of cell 2 + out-of-band interference level of cell 3) within the first time period is greater than or equal to the sixth threshold is not less than the fifth threshold, the terminal reports interference information.

[0159] Design 4 facilitates the network's acquisition of the overall out-of-band interference level of multiple cells, thereby enabling adjustments to the transmitted signal strength of these cells to reduce out-of-band interference and ensure communication. Furthermore, the terminal only reports interference information for these cells if the sum of their out-of-band interference levels is greater than or equal to the sixth threshold and not less than the fifth threshold. In other words, the triggering conditions for interference reporting are more stringent, while relatively relaxing interference restrictions to reduce overhead.

[0160] Optionally, the second ratio is the ratio of the number of times the sum of out-of-band interference levels of the aforementioned multiple cells is greater than or equal to the sixth threshold to the number of second measurements, where the number of second measurements is the number of times the terminal measures the reference signal of the aforementioned multiple cells; or, the second ratio is the ratio of the duration during which the sum of out-of-band interference levels of the aforementioned multiple cells is greater than or equal to the sixth threshold to the first duration.

[0161] For example, within the first time period, the terminal measures the reference signal of multiple cells 10 times. Each measurement can calculate the sum of the out-of-band interference levels of the corresponding multiple cells. If the sum of the out-of-band interference levels of the above multiple cells is greater than or equal to the sixth threshold 3 times, then the second ratio is 30%.

[0162] Another example, taking a first duration of 10 seconds as an example, if the sum of the out-of-band interference levels of the above multiple cells is greater than or equal to the sixth threshold for 5 seconds within those 10 seconds, then the second ratio is 50%.

[0163] Optionally, in Design 4, the interference information includes one or more of the following: the identifiers of the aforementioned multiple cells, the second ratio, the difference between the second ratio and the fifth threshold, the sum of the out-of-band interference levels of the aforementioned multiple cells, or the difference between the sum of the out-of-band interference levels of the aforementioned multiple cells and the sixth threshold.

[0164] In this design, the interference information can also include the sum of the in-band signal strengths of multiple cells. For example, it can be in a scenario where the adjacent channel suppression of each cell is equal. Then, the network device can calculate the out-of-band interference level of the multiple cells based on the adjacent channel suppression of each cell and the sum of the in-band signal strengths of the multiple cells. It should be understood that the above interference information can include the sum of the in-band signal strengths of multiple cells in multiple measurements within the first time period.

[0165] Optionally, within the first time period, the second proportion is greater than or equal to the fifth threshold, including: within the first time period, the sum of the out-of-band interference levels of the aforementioned multiple cells satisfies at least one set of second measurement indicators in one or more sets of second measurement indicators, wherein each set of second measurement indicators includes a sixth threshold corresponding to the sum of the out-of-band interference levels of the aforementioned multiple cells and a fifth threshold corresponding to the second proportion.

[0166] In other words, the network device can be configured with a second set of measurement indicators, which includes a sixth threshold corresponding to the sum of out-of-band interference levels and a fifth threshold corresponding to a second ratio. If the proportion of the sum of out-of-band interference levels of the aforementioned cells that is greater than or equal to the sixth threshold is not less than the fifth threshold, the terminal reports the interference information of the aforementioned cells. The network device can also be configured with multiple sets of second measurement indicators, each set including a sixth threshold corresponding to the sum of out-of-band interference levels and a fifth threshold corresponding to a second ratio. If the sum of out-of-band interference levels of the aforementioned cells satisfies at least one set of second measurement indicators within a first time period, the terminal reports the interference information of those cells. When the network device is configured with multiple sets of second measurement indicators, the larger the sixth threshold in each set, the smaller the fifth threshold can be. This helps the network device determine the out-of-band interference situation of cells with a large sum of out-of-band interference levels.

[0167] Taking out-of-band interference level characterized by I / N as an example, one possible design is that the above-mentioned multiple sets of second measurement indicators include: Measurement indicator 1: The proportion of multiple cells whose cumulative I / N (i.e., the sum of the I / N of multiple cells) is greater than or equal to a1dB is not less than b1%; Measurement indicator 2: The proportion of multiple cells whose cumulative I / N is greater than or equal to a2dB is not less than b2%; Measurement indicator 3: The proportion of multiple cells whose cumulative I / N is greater than or equal to a3dB is not less than b3%; ... The first duration is, for example, 10 seconds.

[0168] Another possible design is that the aforementioned multiple sets of second measurement indicators include: cumulative I / N of b1% not less than a1dB; measurement indicator 2: cumulative I / N of b2% not less than a2dB; measurement indicator 3: cumulative I / N of b3% not less than a3dB; ... where the first duration is, for example, 10 seconds.

[0169] Optionally, the aforementioned interference information is also used to indicate the index of at least one set of second measurement indicators.

[0170] For example, the aforementioned sets of second measurement indicators include: Measurement indicator 1: the proportion of multiple cells with a cumulative I / N greater than or equal to a1dB is not less than b1%; Measurement indicator 2: the proportion of multiple cells with a cumulative I / N greater than or equal to a2dB is not less than b2%; Measurement indicator 3: the proportion of multiple cells with a cumulative I / N greater than or equal to a3dB is not less than b3%; ... For example, a1 > a2 > a3, b1 < b2 < b3. The terminal determines the I / N of one or more adjacent cells of the cell where the terminal is located within a first time period. Assuming that within the first time period, the proportion of the sum of the I / N of cell 1 and cell 2 greater than or equal to a1 exceeds b1, the terminal reports interference information. This interference information includes one or more of the following: the identifiers of cell 1 and cell 2; the proportion of the sum of the I / N of cell 1 and cell 2 greater than or equal to a1; the difference between the proportion of the sum of the I / N of cell 1 and cell 2 greater than or equal to a1 and b1; the sum of the I / N of cell 1 and cell 2 (which can be the value obtained from multiple measurements within the first time period when the sum of the I / N of cell 1 and cell 2 is greater than or equal to a1); the difference between the sum of the I / N of cell 1 and cell 2 and a1; the in-band signal strength of cell 1 and cell 2; or the index of measurement indicator 1 (to identify the measurement indicator). By reporting the index of at least one set of the above-mentioned second measurement indicators, the network device can easily determine which set of second measurement indicators the terminal uses to determine whether the adjacent cell meets the triggering condition.

[0171] Optionally, the first duration is predefined; or, the first duration is configured by the network device.

[0172] For example, the network device sends second configuration information, which is used to configure the first duration. Correspondingly, the terminal receives the second configuration information. The second configuration information and the first configuration information can be carried in the same signaling or in different signaling; this application does not limit this. Configuring the first duration through the network device means that the multiple cells mentioned above are all statistically analyzed for the out-of-band interference level within that duration, which helps ensure the stability of the statistically analyzed out-of-band interference level.
