[0092] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.
[0093] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.
[0094] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0095] See also Figure 1 , Figure 1 is a flow chart of a signal processing method provided by an embodiment of the present invention, which is applied to a first base station, such as Figure 1 As shown, the following steps are included:
[0096] Step 101: Generate a SSB-like signal.
[0097] In the embodiment of the present invention, the meaning of the quasi-SSB signal is that the structure of the signal is similar to that of the SSB signal in the prior art, but the function is different. In the embodiment of the present invention, the quasi-SSB signal can be used to indicate that the sender of the quasi-SSB signal is an interference source. That is to say, if the receiver detects that the received signal includes a quasi-SSB signal, it can be determined that the sender is an interference source. For example, the quasi-SSB signal can use the SSB signal in the prior art, or the quasi-SSB signal can also include a part of the existing SSB signal, or the quasi-SSB signal can also be obtained by changing the SSB signal in the prior art.
[0098] In order to enable interference detection between base stations with different time slot ratios (such as 1D3U and 2.5ms dual-periodic frame structures), in an embodiment of the present invention, a reference signal (quasi-SSB signal) designed based on SSB is used to perform interference detection. Specifically, in an embodiment of the present invention, a quasi-SSB signal can be generated in at least one of the following ways:
[0099] (1) Using an SSB signal as the quasi-SSB signal, wherein the SSB signal includes: PSS, SSS and PBCH. That is, in this case, an SSB signal in the prior art is used as the quasi-SSB signal.
[0100] (2) The SSB-like signal is formed by using one or two of PSS, SSS and PBCH.
[0101] For example, the SSB-like signal is formed using PSS or SSS, or the SSB-like signal is formed using PSS.
[0102] (3) The SSB-like signal is formed by using PSS, SSS and PBCH, wherein the relative position relationship between PSS, SSS and PBCH in the SSB-like signal is different from the relative position relationship between PSS, SSS and PBCH in the SSB signal.
[0103] like Figure 2 As shown in the figure, the composition of the SSB signal in the prior art and the relative position relationship between PSS, SSS and PBCH in the SSB signal. Among them, PSS is located in the middle 127 subcarriers of symbol 0; SSS is located in the middle 127 subcarriers of symbol 2; in order to protect PSS and SSS, they have different subcarrier Set 0 at both ends. PBCH is located in symbol 1 / 3 and symbol 2, among which, symbol 1 / 3 occupies all subcarriers from 0 to 239, and symbol 2 occupies all subcarriers except the subcarriers occupied by SSS and the subcarrier Set 0 protecting SSS.
[0104] In the embodiment of the present invention, the relative position relationship between the PSS, SSS and PBCH in the SSB signal is changed to be different from Figure 2 The relative position relationship in the prior art shown in the figure obtains a SSB-like signal. Figure 3 As shown, it is a schematic diagram of a quasi-SSB signal in an embodiment of the present invention, wherein the relative position relationship between PSS, SSS and PBCH is changed compared with the position in the prior art.
[0105] Step 102: Send a SSB-like signal to a second base station, and the second base station determines that the first base station is an interfering base station by detecting the SSB-like signal.
[0106] Among them, the downlink position of the SSB-like signal can be the downlink position of SSB in the prior art, or other downlink positions (including frequency domain and time domain) within a sending period of an SSB signal can be used as the sending position of the SSB-like signal.
[0107] Specifically, in this step, the SSB-like signal may be sent using the inherent downlink position of the SSB signal in the transmission period of the SSB signal; or, the SSB-like signal may be sent using other downlink positions other than the inherent downlink position of the SSB signal in the transmission period of the SSB signal. The inherent downlink position of the SSB signal refers to the downlink position of the SSB signal in the prior art.
[0108] Regarding the use of the SSB signal as the quasi-SSB signal in step 101, in order to distinguish the SSB signal from the quasi-SSB signal, the SSB signal may be sent in a normal manner, while the quasi-SSB may be sent at other downlink positions other than the inherent downlink position of the SSB signal.
[0109] like Figure 4 As shown, an SSB signal is sent at position 41 within the cycle, and a quasi-SSB signal is sent at any position between 42 and 44. In the prior art, the duration of SSB transmission is different at different SCS (sub-carrier space) intervals in different frequency bands. Taking the 4.9GHz band and 30KHz subcarrier spacing as an example, the SSB signal needs to be sent for a fixed continuous 2ms within the cycle. Then, a quasi-SSB signal can be sent at other downlink positions within the cycle.
[0110] In the embodiment of the present invention, the first base station sends a quasi-SSB signal to the second base station, so that the second base station can determine that the first base station is an interfering base station when detecting that the received signal includes the quasi-SSB signal. Therefore, using the solution of the embodiment of the present invention, the interfering base station can be determined without introducing a new pilot, thereby reducing the overhead and complexity of determining interference between base stations.
[0111] In addition, in an embodiment of the present invention, the first base station may also send first information to the second base station, where the first information includes configuration information of the SSB-like signal.
[0112] In actual applications, base stations can communicate SSB signals and SSB-like signal configurations, including PCI (Physical Cell Identifier) configurations, frequency domain and time domain location information, so that the interfered base station can determine the timing relationship of the specific pilot. For example, interfaces based on X2 / Xn / S1 / Ng can be extended to carry the above configuration information through a field of the interface intercommunication message.
[0113] In addition, for the first base station, it may also be an interfered base station. Therefore, when the first base station detects that the third base station is an interfering base station, it sends second information to the third base station. The second information includes interference information of the third base station detected by the first base station.
[0114] Specifically, the base station can detect SSB signals and SSB-like signals in a predetermined time and frequency domain, and when a SSB-like signal can be detected, it can provide feedback to the interfering base station, including strength information, SSB signals and SSB-like signal sequence numbers, etc. For example, interfaces based on X2 / Xn / S1 / Ng can be extended, and the above configuration information can be carried in a field of the interface intercommunication message.
[0115] See also Figure 5 , Figure 5 is a flow chart of a signal processing method provided by an embodiment of the present invention, which is applied to a second base station, such as Figure 5 As shown, the following steps are included:
[0116] Step 501: Receive a signal sent by a first base station.
[0117] The signal sent by the first base station may be an SSB signal or other signals.
[0118] Step 502: Detect the signal.
[0119] The second base station may detect the signal to determine whether the first base station is an interfering base station. In order to improve detection efficiency, in an embodiment of the present invention, the second base station may receive first information sent by the first base station, the first information including configuration information of the SSB-like signal, and detect the signal according to the configuration information. The configuration information includes configurations such as PCI, frequency domain, and time domain location information.
[0120] Step 503: When it is detected that the signal includes a SSB-like signal, determine that the first base station is an interfering base station.
[0121] Specifically, in this step, when the second base station detects that the signal includes an SSB signal and the downlink position of the SSB signal is different from the inherent downlink position of the SSB signal in the sending period of the SSB signal, it determines that the first base station is an interfering base station.
[0122] Alternatively, when it is detected that the signal includes a quasi-SSB signal formed by using one or two of the PSS, SSS, and PBCH, the second base station determines that the first base station is an interfering base station;
[0123] Alternatively, when it is detected that the signal includes an SSB-like signal formed by using PSS, SSS and PBCH, the second base station determines that the first base station is an interfering base station, wherein the relative position relationship between PSS, SSS and PBCH in the SSB-like signal is different from the relative position relationship between PSS, SSS and PBCH in the SSB signal.
[0124] In the embodiment of the present invention, the first base station sends a quasi-SSB signal to the second base station, so that the second base station can determine that the first base station is an interfering base station when detecting that the received signal includes the quasi-SSB signal. Therefore, using the solution of the embodiment of the present invention, the interfering base station can be determined without introducing a new pilot, thereby reducing the overhead and complexity of determining interference between base stations.
[0125] It can be seen from the above description that in an embodiment of the present invention, by broadcasting SSB-like signals, planning corresponding positions and scrambling codes, the interfered base station can locate the interfering base station according to whether the SSB-like signal of the interfering base station is detected during its uplink reception.
[0126] In addition, the second base station may also send third information to the first base station, where the third information includes interference information of the first base station detected by the second base station, including strength information, serial numbers of SSB signals and SSB-like signals, etc.

Since the principle of solving the problem by the signal processing device is similar to that of the signal processing method in the embodiment of the present invention, the implementation of the signal processing device can refer to the implementation of the method, and the repeated parts will not be repeated.

[0130] Sending the SSB-like signal using the inherent downlink position of the SSB signal in the transmission period of the SSB signal; or
[0131] The SSB-like signal is sent by utilizing other downlink positions in the transmission cycle of the SSB signal except for the inherent downlink position of the SSB signal.
