Technical Field

Background
The 5G communication system may face a problem of large interference due to uplink and downlink collisions between cells caused by coexistence of various frame structures. For example, in the 4.9G band, in the to C-oriented scenario, a 2.5ms double period is usually adopted as the lower line; for the to B scene, a frame structure of 1D3U may be adopted. Different frame structures are adopted in different areas, which may cause interference of uplink and downlink cross time slots among base stations.

However, this scheme is costly and complex due to the need to introduce new pilots and the complex sequence.

Detailed Description
The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a signal processing method according to an embodiment of the present invention, applied to a first base station, as shown in fig. 1, including the following steps:
step 101, generating SSB-like signals.
In the embodiments of the present invention, the meaning of SSB-like signals means that the signals are similar in structure to the SSB signals in the prior art, but function differently. In an embodiment of the present invention, the SSB-like signal may be used to indicate that the sender of the SSB-like signal is an interferer. That is, if the receiving side detects that the SSB-like signal is included in the received signal, it can be determined that the transmitting side is an interference source. For example, the SSB signal may be an SSB signal in the prior art, or the SSB signal may further include a part of the existing SSB signal, or the SSB signal may be obtained by modifying an SSB signal in the prior art.
In order to enable interference detection between base stations with different slot ratios (e.g., 1D3U and 2.5ms bi-periodic frame structure), in the embodiment of the present invention, a reference signal (SSB-like signal) based on SSB design is used for interference detection. Specifically, in the embodiment of the present invention, the SSB-like signal may be generated according to at least one of the following manners:
(1) utilizing an SSB signal as the SSB-like signal, wherein the SSB signal comprises: PSS, SSS and PBCH. That is, in this case, the SSB signal in the related art is used as the SSB-like signal.
(2) The SSB-like signals are formed using one or both of PSS, SSS and PBCH.
For example, the SSB-like signals are formed using PSS, SSS, or the SSB-like signals are formed using PSS.
(3) And forming the SSB-like signals by using the PSS, the SSS and the PBCH, wherein the relative position relationship among the PSS, the SSS and the PBCH in the SSB-like signals is different from the relative position relationship among the PSS, the SSS and the PBCH in the SSB signals.
Fig. 2 shows the composition of the SSB signals and the relative position relationship among PSS, SSS, and PBCH in the SSB signals in the prior art. Wherein, the PSS is located at 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, there are different subcarriers Set 0 at both ends. The PBCH is located at symbol 1/3 and symbol 2, where symbol 1/3 occupies all subcarriers from 0 to 239, and symbol 2 occupies all subcarriers except the subcarriers occupied by SSS and the subcarriers Set 0 protecting SSS.
In the embodiment of the present invention, the relative position relationship among the PSS, the SSS, and the PBCH in the SSB signal is changed to be different from the relative position relationship in the prior art shown in fig. 2, so as to obtain the SSB-like signal. For example, as shown in fig. 3, it is a schematic diagram of SSB-like signals in an embodiment of the present invention, where a relative position relationship between the PSS, the SSS, and the PBCH is changed with respect to a position in the prior art.
Step 102, sending an SSB-like signal to a second base station, where the second base station detects the SSB-like signal to determine that the first base station is an interfering base station.
The downlink position of the SSB-like signal may be a downlink position of an SSB in the prior art, or other downlink positions (including a frequency domain and a time domain) in a transmission period of an SSB-like signal may be used as the transmission position of the SSB-like signal.
Specifically, in this step, the SSB-like signal may be transmitted using a unique downlink position of the SSB signal in a transmission period of the SSB signal; alternatively, the SSB-like signal is transmitted using a downlink position other than the specific downlink position of the SSB signal in the transmission cycle of the SSB signal. The inherent downstream position of the SSB signal refers to the downstream position of the SSB signal in the prior art.
In step 101, the SSB signal is used as the SSB-like signal, and in order to distinguish the SSB signal from the SSB-like signal, the SSB signal may be transmitted in a normal transmission manner, and the SSB-like signal may be transmitted at a downlink position other than the specific downlink position of the SSB signal.
As shown in fig. 4, SSB signals are transmitted at 41 locations within the cycle and SSB-like signals are transmitted at any of 42-44 locations. In the prior art, the SSB transmission duration is different at different sub-carrier space (SCS) intervals in different frequency bands. Taking the 4.9GHz band and the 30KHz subcarrier spacing as an example, the SSB signal needs to be transmitted within a fixed period of 2ms continuously. Then SSB-like signals may be sent at other downstream locations within the cycle.
In the embodiment of the present invention, the first base station sends the SSB-like 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 SSB-like signal. Therefore, by using the scheme of the embodiment of the invention, the interference base station can be determined without introducing new pilot frequency, thereby reducing the expense and complexity for determining the interference between the base stations.
In addition, in this embodiment of the present invention, the first base station may further send first information to the second base station, where the first information includes configuration information of the SSB-like signal.
In practical application, the configurations of SSB signals and SSB-like signals that can be communicated between base stations include PCI (Physical Cell Identifier) and other configurations, frequency domain and time domain location information, so that the interfered base station can determine the timing relationship of a specific pilot. For example, an interface based on X2/Xn/S1/Ng, etc. may be extended, and the above configuration information is carried by a certain field of the interface interworking message.
In addition, it may be the interfered base station for the first base station, and therefore, when detecting that the third base station is the interfering base station, the first base station transmits second information to the third base station, where the second information includes the interference information of the third base station detected by the first base station.
Specifically, the base station may perform detection on the SSB signal and the SSB-like signal in a predetermined time-frequency domain, and when the SSB-like signal is detected, the SSB-like signal is fed back to the interfering base station, including the strength information, the sequence numbers of the SSB signal and the SSB-like signal, and the like. For example, an interface based on X2/Xn/S1/Ng, etc. may be extended, and the above configuration information is carried by a certain field of the interface interworking message.
Referring to fig. 5, fig. 5 is a flowchart of a signal processing method according to an embodiment of the present invention, applied to a second base station, as shown in fig. 5, including the following steps:
step 501, receiving a signal sent by a first base station.
The signal transmitted by the first base station may be an SSB signal, or may be another signal.
Step 502, detecting the signal.
The second base station may detect the signal to determine whether the first base station is an interfering base station. In order to improve the detection efficiency, in this embodiment of the present invention, the second base station may receive first information sent by the first base station, where the first information includes configuration information of the SSB-like signal, and detect the signal according to the configuration information. The configuration information includes PCI and other configurations, and frequency domain and time domain position information.
Step 503, when it is detected that the signal includes an SSB-like signal, determining that the first base station is an interfering base station.
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 transmission period of the SSB signal, it determines that the first base station is an interfering base station.
Or when detecting that the signal includes an SSB-like 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;
or when detecting that the signals include an SSB-like signal formed by using the PSS, SSS, and PBCH, the second base station determines that the first base station is an interfering base station, where a relative position relationship among the PSS, SSS, and PBCH in the SSB-like signal is different from a relative position relationship among the PSS, SSS, and PBCH in the SSB-like signal.
In the embodiment of the present invention, the first base station sends the SSB-like 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 SSB-like signal. Therefore, by using the scheme of the embodiment of the invention, the interference base station can be determined without introducing new pilot frequency, thereby reducing the expense and complexity for determining the interference between the base stations.
As can be seen from the above description, in the embodiment of the present invention, through the broadcasted SSB-like signal, the corresponding location and scrambling code are planned, and when the victim base station receives the SSB-like signal, the victim base station can locate the interfering base station according to whether the SSB-like signal of the offending base station is detected.
In addition, the second base station may further 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, sequence numbers of the SSB signal and the SSB-like signal, and the like.
