Description

Technical Field

[0001] The present invention relates to the field of wireless technology, and in particular to a signal interference processing method, device, communication equipment and storage medium. Background Art

[0002] Repeaters are primarily used to fill coverage gaps. Traditional RF analog repeaters cannot demodulate received downlink (DL) data channels and, therefore, cannot distinguish the cell from which the received DL signal originates. Repeaters amplify all received DL signals. Automatic power control ensures that the final output power of the repeater is less than or equal to the target output power, regardless of input signal power differences. This amplifies the serving cell signal while also amplifying interference signals from other cells (such as neighboring cells), causing co-channel interference. Summary of the Invention

[0051] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] A traditional RF analog repeater is a wireless signal relay product, which mainly includes components or modules such as antennas, RF duplexers, low-noise amplifiers, mixers, electrically adjustable attenuators, filters, and power amplifiers, including uplink and downlink amplification links, thereby achieving two-way communication between base stations and mobile stations.

[0053] Figure 1 is a schematic diagram of the same-frequency interference scenario; Figure 1 As shown, the repeater is located within the coverage area of ​​base station A, serving terminal a1. Terminal a2 is directly served by base station A. Base station B is a co-frequency neighboring cell.

[0054] The repeater only serves base station A. Signals other than those from base station A (e.g., signals from base station B) interfere with the terminals connected to the repeater. This embodiment of the present invention only considers scenarios where there is a one-to-many relationship between base stations and repeaters. This means that one base station can be deployed with one or more repeaters, and each repeater only compensates for the coverage blind spots of its corresponding base station and is not responsible for compensating for the coverage blind spots of other base stations.

[0055] Currently, the repeater only demodulates part of the received control information to obtain the uplink and downlink time slot configuration. For user data, the repeater only performs simple amplification and forwarding and does not have the user data decoding and re-encoding functions.

[0056] Since traditional repeaters cannot demodulate the received DL data channels, they cannot distinguish which cell the received DL signal comes from. The repeater amplifies all received DL signals. The automatic power control capability ensures that regardless of whether there is a difference in the input signal power, the final repeater output power value is less than or equal to the target output power value. Thus, while amplifying the serving cell signal (such as the signal sent by base station A), it also amplifies the neighboring cell interference signal (such as the signal sent by base station B), causing co-channel interference. For example, in some scenarios, since the propagation loss between the repeater and the host base station (such as base station A) is small, the repeater needs to perform power compression when amplifying the signal of the host base station. That is, assuming that the maximum gain of the repeater is 90dB, due to power compression, the amplification gain of the host base station signal is 30dB. Considering the large propagation loss between the repeater and the co-frequency neighboring cell (interference source), the amplification gain of the repeater for the co-frequency neighboring cell base station signal can be maintained at a maximum gain of 90dB, thereby amplifying the co-frequency neighboring cell interference. For details, please refer to Figure 1 In addition, because the repeater amplifies the interference signal of the adjacent cell with the same frequency, for the terminal in the current cell not covered by the repeater, the repeater amplifies the interference of the adjacent cell with the same frequency, raises the noise floor, and affects the downlink reception of such terminals. For details, see Figure 1 The interference suffered by terminal a2.

[0057] like Figure 1 In the scenario shown, due to the presence of repeaters, the interference is as follows:

[0058] For terminal a2: Due to the presence of the repeater, the interference signal from base station B received by terminal a2 is amplified by the repeater, making the interference signal stronger and seriously affecting the normal operation of terminal a2.

[0059] For terminal a1:

[0060] Scenario 1) Assume that the repeater experiences a certain amount of gain compression when amplifying the signal from base station A, while amplifying the signal from base station B at maximum gain. In this case, terminal a1 is subject to significant interference from the signal from base station B. Note that, in this case, there is a time difference between the arrival of the signals from base stations A and B at the repeater. This time difference allows the repeater to perform automatic gain adjustment.

[0061] Scenario 2) The repeater amplifies the signals from base station A and base station B at a constant gain. The amplified base station B signal is too high to reach the receiving noise floor of terminal a1, affecting the signal reception of terminal a2.

[0062] Based on this, the following embodiments of the present invention are proposed.

[0063] An embodiment of the present invention provides a signal interference processing method, which is applied in a repeater. Figure 2Schematic diagram of the signal interference processing method according to an embodiment of the present invention Figure 1 ;like Figure 2 As shown, the method includes:

[0064] Step 101: The repeater receives signals from multiple base stations and detects the power of each of the multiple signals.

[0065] Step 102: The repeater determines whether co-channel interference can be generated based on the power of the multiple signals, and executes an interference avoidance solution when it is determined that co-channel interference can be generated.

[0066] By adopting the technical solution of the embodiment of the present invention, the power of the signals of the surrounding base stations is detected by the repeater to determine whether co-channel interference can be generated, and if co-channel interference can be generated, an interference avoidance solution is implemented; in this way, interference between co-frequency cells is avoided and interference between co-frequency cells is reduced.

[0067] In some optional embodiments, the repeater determines whether co-channel interference can be generated based on the power of the multiple signals, including: the repeater determines whether the power of the signal corresponding to the non-host base station exceeds a first threshold value; if the power of the signal corresponding to the non-host base station exceeds the first threshold value, determining that the non-host base station generates co-channel interference on the terminal served by the host base station to which the repeater belongs; or

[0068] The repeater determines whether the power difference between two signals corresponding to two base stations within a preset time range is less than a second threshold value; if the power difference between the two signals corresponding to the two base stations is less than the second threshold value, it is determined that the non-host base station generates co-channel interference to the terminal served by the host base station to which the repeater belongs; or

[0069] The repeater determines whether the power difference between the two original unamplified signals corresponding to the two base stations within a preset time range is greater than a third threshold value; if the power difference between the two unamplified signals corresponding to the two base stations is greater than the third threshold value, it is determined that the non-host base station generates co-channel interference to the terminal served by the host base station to which the repeater belongs.

[0070] In this embodiment, in one implementation, the repeater receives signals from multiple base stations and analyzes whether each signal comes from a host base station or a non-host base station. Exemplarily, the repeater can determine whether the source of the signal is a host base station or a non-host base station based on the physical cell identifier (PCI) carried in the signal by detecting and analyzing the PCI; and then determine whether the power of the signal corresponding to the non-host base station exceeds the first threshold value. If it is determined that the power of the signal corresponding to the non-host base station exceeds the first threshold value, it is determined that the non-host base station generates co-channel interference to the terminal served by the host base station to which the repeater belongs. Alternatively, if the repeater determines that the power of the signal corresponding to the non-host base station exceeds the threshold value after amplification, it can also be determined that the non-host base station generates co-channel interference to the terminal served by the host base station to which the repeater belongs. For example Figure 1 In the example shown, the repeater determines through PCI that the host base station is base station A and the non-host base station is base station B. If the power of the signal corresponding to base station B exceeds the first threshold, it can be determined that co-channel interference can occur.

[0071] In another embodiment, within a preset time range, the repeater determines whether the power difference between two amplified signals corresponding to two base stations is less than a second threshold value; wherein, one of the two base stations is a host base station and the other is a non-host base station; if the repeater determines that the power difference between the two amplified signals corresponding to the two base stations is less than the second threshold value, it can be determined that the non-host base station generates co-channel interference to the terminal served by the host base station to which the repeater belongs. For example Figure 1 In the example shown, if the power difference between the two amplified signals of base station A and base station B is less than the second threshold value, it is considered that due to the presence of the repeater, co-channel interference occurs between base station A and base station B, and base station B generates co-channel interference to the terminal served by base station A.

[0072] In another embodiment, within a preset time range, the repeater determines whether the difference between two original unamplified signal powers corresponding to two base stations is greater than a third threshold value; wherein, among the two base stations, one base station is a host base station and the other base station is a non-host base station; if the repeater determines that the difference between two original unamplified signal powers corresponding to the two base stations is greater than the third threshold value, it can be determined that the non-host base station generates co-channel interference to the terminal served by the host base station to which the repeater belongs.

[0073] As an implementation mode, the execution of the interference avoidance scheme includes: the repeater does not amplify non-host base station signals that can generate co-channel interference.

[0074] In this embodiment, the interference avoidance solution is implemented by the repeater. Specifically, the repeater does not amplify non-host base station signals that can generate co-channel interference. In this way, co-channel interference generated by the non-host base station to the terminals served by the host base station will not be generated.

[0075] As another implementation, the execution of the interference avoidance scheme includes: the repeater sending interference information to at least some of the multiple base stations, where the interference information represents information of base stations that can generate co-channel interference.

[0076] In this embodiment, the repeater sends interference information to at least some base stations, and at least some base stations execute interference avoidance solutions based on the received interference information. That is, the repeater assists the base stations in executing interference avoidance.

[0077] In some optional embodiments of the present invention, the interference information includes at least one of the following information: the identifier of the repeater, the identifier of the base station that can generate co-channel interference, the power of the signal corresponding to the detected base station, the power difference between the two signals corresponding to the two base stations, and the detection time information.

[0078] In some optional embodiments of the present invention, the method for determining the identifier of the repeater includes:

[0079] The repeater determines the identifier of the repeater according to preset sequence information; or,

[0080] The repeater obtains a sequence information set and determines an identifier of the repeater according to sequence index information in the sequence information set; or

[0081] The identifier of the repeater corresponds to a transmission resource for transmitting the interference information.

[0082] In this embodiment, the above-mentioned interference information sent by the repeater to the base station may include at least one of the following: the identifier of the repeater (such as the ID of the repeater), the identifier of the base station that can generate co-frequency interference, the power of the signal corresponding to the detected base station, the power difference between the two signals corresponding to the two base stations, and the detection time information.

[0083] As an embodiment, the identity of a repeater can be determined by preset sequence information. For example, each repeater can be uniquely identified by a preset pseudo-random sequence. The pseudo-random sequence that uniquely identifies a repeater can represent the repeater's global identity information or local identity information. For example, within each Tracking Area (TA), all repeaters can use the same pseudo-random sequence, and different repeaters can correspond to different initial values.

[0084] As another embodiment, a repeater can obtain a sequence information set and determine the repeater's identity based on the sequence index information in the sequence information set. Exemplarily, within each TA range, all repeaters correspond to a pseudo-random sequence set, which includes multiple pseudo-random sequences. Different repeaters can select a pseudo-random sequence from the pseudo-random sequence set based on different sequence index information, and determine the repeater's identity based on the selected pseudo-random sequence. For example, a repeater can select a pseudo-random sequence from all configured pseudo-random sequences based on a factory ID or SIM card number. For example, the repeater's factory ID or the last N digits of the Subscriber Identity Module (SIM) card number can be used as the sequence index of the currently selected pseudo-random sequence. Alternatively, the total number of pseudo-random sequences mod divided by the repeater's factory ID or the total number of pseudo-random sequences mod divided by the last N digits of the SIM card number can be used as the sequence index of the currently selected pseudo-random sequence.

[0085] As another embodiment, the identifier of the repeater corresponds to the transmission resource for transmitting the interference information, that is, different repeaters can use different transmission resources for transmitting interference information, thereby implicitly indicating the identifier of the repeater through the transmission resource. Exemplarily, the transmission resource may include an SRS resource, and the SRS resource may be a dedicated SRS resource configured for the repeater, or an SRS resource shared by the repeater and the UE. For example, different repeaters randomly select different SRS set IDs or resource IDs, or different time domain periods or different frequency positions, and the base station can determine the identifier of the repeater based on the above information and the known positions of all repeaters.

[0086] In some optional embodiments, the repeater sends interference information to at least some of the multiple base stations, including: the repeater sends the interference information to the base station on pre-agreed transmission resources.

[0087] In this embodiment, the repeater sends the interference information to the base station on pre-agreed transmission resources to inform the base station which base stations may interfere and assist the base station in taking certain interference avoidance measures. The transmission resources may be time domain resources and / or frequency domain resources.

[0088] In some other optional embodiments, the repeater sends interference information to at least some of the multiple base stations, including: the repeater sends the interference information to the base station on the transmission resources indicated by the base station.

[0089] Optionally, the method further includes: the repeater receiving control information from the base station, the control information including configuration information of the transmission resource.

[0090] In this embodiment, before sending interference information to the base station, the repeater may receive control information from the base station in advance, wherein the control information includes configuration information of the transmission resource. The repeater may determine the transmission resource for transmitting the interference information based on the configuration information of the transmission resource.

[0091] In this embodiment, the transmission resources include time-frequency resources and / or sounding reference signal (SRS) resources.

[0092] Based on the above embodiments, an embodiment of the present invention further provides a signal interference processing method, which is applied in a base station. Figure 3 Schematic diagram of the signal interference processing method according to an embodiment of the present invention Figure 2 ;like Figure 3 As shown, the method includes:

[0093] Step 201: The base station obtains interference information related to the repeater; the interference information indicates information about base stations that can generate co-channel interference;

[0094] Step 202: Execute an interference avoidance solution based on the interference information.

[0095] By adopting the technical solution of the embodiment of the present invention, interference information related to the repeater is obtained by the base station; an interference avoidance solution is implemented based on the interference information, thereby avoiding interference between cells with the same frequency and reducing interference between cells with the same frequency.

[0096] As an implementation manner, the base station obtains interference information related to the repeater, including: the base station receives the interference information from the repeater.

[0097] In this embodiment, through the above embodiment, the repeater sends interference information indicating base stations that can generate co-channel interference to the base station, so that the base station obtains the interference information and executes the interference avoidance solution.

[0098] In some optional embodiments, after the base station receives the interference information from the repeater, the method may further include: the base station sending the interference information to other base stations. Exemplarily, the base station may send the interference information to other base stations within a TA range via an X2 interface.

[0099] As another implementation manner, the base station obtains interference information related to the repeater, including: the base station determines the interference information related to the repeater based on pre-acquired repeater deployment information and measurement information reported by the user equipment.

[0100] In this embodiment, the base station has pre-obtained repeater deployment information. This repeater deployment information may include, for example, the deployment location of each repeater and its corresponding repeater identification information. Furthermore, based on the repeater deployment information and measurement information reported by the user equipment (UE), the base station can determine interference information related to the repeaters, such as whether the presence of the repeaters can cause co-channel interference.

[0101] In some optional embodiments of the present invention, executing an interference avoidance scheme based on the interference information includes: the base station executing at least one of the following schemes: adjusting frequency position information, adjusting beam information, and adjusting power information.

[0102] In this embodiment, if the base station determines other cells that can generate co-channel interference through the above method, the base station and other base stations corresponding to the other cells may coordinate with each other to avoid mutual co-channel interference. Exemplarily, the base station may implement at least one of the following solutions: adjusting frequency location information, adjusting beam information, and adjusting power information to avoid mutual co-channel interference; or, the base station may send a message to the other base stations to enable the other base stations to avoid mutual co-channel interference by adjusting at least one of frequency location information, beam information, and power information.

[0103] The signal interference processing method according to the embodiment of the present invention is described below with reference to a specific example.

[0104] Figure 4 FIG. 1 is a flow chart of the interaction of the signal interference processing method according to an embodiment of the present invention; in this example, the repeater serves cell A. Figure 4 As shown, the method may include:

[0105] Step 301: Base station A to which cell A belongs sends first downlink control information to a repeater, and base station B to which cell B belongs sends second downlink control information to the repeater.

[0106] Step 302: The repeater demodulates the first downlink control information and the second downlink control information respectively, and obtains the cell identifier of cell A and the cell identifier of cell B.

[0107] Step 303: The repeater determines whether the power of the signal of cell B exceeds the first threshold, or whether the power difference between the signals of the two cells exceeds the second threshold; if the result of the determination is no, execute step 304; if the result of the determination is yes, execute step 305.

[0108] Step 304: The repeater amplifies and power-compresses the first downlink control information before forwarding it, and amplifies and forwards the second downlink control information. The process ends.

[0109] Step 305: The repeater sends interference information to base station A and base station B respectively on the agreed transmission resources. The interference information indicates information of base stations that can generate co-channel interference.

[0110] The interference information may include at least one of the following information: the identifier of the repeater, the identifier of the base station that can generate co-channel interference, the power of the signal corresponding to the detected base station, the power difference between the two signals corresponding to the two base stations, and the detection time information.

[0111] Step 306: inform the surrounding cells of the interference situation. For example, base station A sends interference information to base station B, including the repeater ID; base station B sends interference information to base station A, including the repeater ID.

[0112] Step 307: Base station A and base station B coordinate information transmission configuration, for example, executing at least one of the following solutions: adjusting frequency position information, adjusting beam information, and adjusting power information.

[0113] Here, if each base station finds interference information with the same repeater identifier sent by a surrounding base station, the two base stations coordinate information transmission configuration, such as executing at least one of adjusting frequency position information, adjusting beam information, and adjusting power information to avoid co-channel interference.

[0114] Based on the above embodiments, an embodiment of the present invention further provides a signal interference processing device.
