Background technique

As we all know, it is difficult to make phone calls or surf the Internet on an airplane because there is no network coverage in the air like on the ground. One way to achieve this is based on aircraft communication with ground base stations.

However, the flight altitude of the aircraft is above 10,000 meters, and to ensure continuous coverage within an economically affordable range, the coverage area of a single base station must be large enough, that is, the distance between ground base stations will be very large. This leads to a high transmission power of the ground base station, which may cause serious radio interference between the ground base station and the Public Land Mobile Network (PLMN) base station. How to avoid the radio interference between the ground base station and the PLMN base station used to communicate with the flight is an urgent problem to be solved.

In order to better understand the embodiment of the present application, the ground base station-based aircraft communication related to the present application will be described.

As we all know, it is difficult to make phone calls or surf the Internet on an airplane because there is no network coverage in the air like on the ground. Usually, if communication is to be carried out, it will be based on satellite communication network, but the communication cost is very high, and the capacity is small, so it is difficult to popularize. Therefore, the aircraft communication based on the ground base station becomes a potential direction.

For example, as shown in Figure 2, different ground base stations are used to achieve continuous coverage on the aircraft route to ensure that the aircraft can always have network connection services. But this approach also has its problems. Generally, the flying altitude of an aircraft is more than 10,000 meters. To ensure continuous coverage within an economical range, the coverage area of a single ground base station must be large enough, that is, the distance between ground base stations will be very large. Large, which leads to high transmission power of ground base stations, which may cause more serious radio interference. The worst case of such radio interference occurs when the spectrum used by the terrestrial base station overlaps or is adjacent to the spectrum of the PLMN base station (such as gNB), as shown in Figure 3. Improper interference avoidance will cause serious performance loss and even cause aircraft danger.

In addition, the base station used to communicate with the aircraft needs to have a high transmission power to achieve a large enough air cell coverage radius. At the same time, due to the limited number of aircraft in the air and the scattered elapsed time of aircraft, the actual use efficiency of ground base stations is relatively low. Usually, in order to improve the utilization rate of spectrum resources, operators usually use the same spectrum (such as 100MHz bandwidth of n79 frequency band) or adjacent spectrum to deploy ground base stations and PLMN base stations (such as gNB), which actually causes mutual interference. frequency interference or adjacent frequency interference.

Based on the above problems, this application proposes an interference avoidance solution, which can reduce the mutual interference between the ground base station and the PLMN base station (such as gNB).

The technical scheme of the present application is described in detail below through specific examples.

Fig. 4 is a schematic flowchart of an interference avoidance method 200 according to an embodiment of the present application. As shown in Fig. 4, the method 200 may include at least some of the following contents:

S210, the first base station avoids interference with the second base station by coordinating time-frequency resources with the second base station; wherein, the first base station is used to communicate with the flight terminal, and the second base station is a PLMN base station ; or, the first base station is a PLMN base station, and the second base station is used to communicate with the flight terminal.

In this embodiment of the present application, the time-frequency resources are coordinated between the first base station and the second base station, so as to prevent the first base station and the second base station from using the same frequency domain resources at the same time, or to avoid the first base station and the second base station from occupying the same time-frequency resources, thereby avoiding mutual interference between the first base station and the second base station.

In some embodiments, it is assumed that the first base station is used to communicate with the flight terminal, and the second base station is a PLMN base station. The ground base station for communication usually has a very high transmission power. The first base station can be some base stations specially used for communicating with flight terminals, or some other base stations can be reused, which is not limited in this application; the second base station It is a PLMN base station, for example, eNB, gNB and so on.

In some embodiments, the flight terminal may be a device with flight capabilities, such as an airplane, a drone, a hot air balloon, a flying car, etc., the flight terminal may also be a terminal carried by a device with flight capabilities, and the flight terminal may also be a The embodiment of the present application does not limit the terminal carried by the passenger carrying the device capable of flying.

Optionally, in some embodiments, the above S210 may specifically be:

When the priority of the service corresponding to the first base station is higher than the priority of the service corresponding to the second base station, the first base station sends first information to the second base station; wherein the first information is used to indicate The second base station remains silent within the first time period, or the first information is used to indicate that the first base station occupies resources within the first time period.

That is, after receiving the first information, the second base station may know that the first base station requires the second base station to remain silent within the first time period, or may know that the first base station has occupied the first time period resources within. Further, the second base station keeps silent within the first duration based on the first information.

Optionally, the first duration is determined according to at least one of the following:

The service duration corresponding to the first base station, and the residence time of the equipment communicating with the first base station in the cell served by the first base station.

For example, assuming that the first base station is used to communicate with the flight terminal, and the second base station is a PLMN base station, in this case, the communication service between the flight terminal and the first base station has a higher priority. Then, when a flying terminal is about to enter the air cell where the first base station is located, the first base station obtains information such as the flight path and speed of the flying terminal, thereby obtaining the time information when the flying terminal enters and leaves the air cell. During the time period corresponding to the time information (that is, the above-mentioned first duration), the first base station will remain on. In addition, the first base station notifies the second base station (such as gNB) in the adjacent area of the time period corresponding to the time information (that is, the first duration). After receiving the information, the second base station switches the ground terminals in the cell to other frequency points for work. Therefore, the second base station is kept silent at the communication frequency in the air, so as to avoid interference to the communication between the first base station and the flight terminal.

For another example, assume that the first base station is a PLMN base station, and the second base station is used to communicate with the flight terminal. In this case, the communication service between the ground terminal and the first base station has a higher priority. Then, when a ground terminal is about to enter the cell where the first base station is located, the first base station can learn the time information when the ground terminal enters and leaves the cell where the first base station is located. During the time period corresponding to the time information (that is, the above-mentioned first duration), the first base station will remain on. In addition, the first base station notifies the second base station (such as a ground base station) in the adjacent area of the time period corresponding to the time information (that is, the first duration). After receiving the information, the second base station switches the flying terminals in the cell to other frequency points to work. Therefore, the second base station is kept silent at the communication frequency point where the first base station works, so as to avoid interference to the communication between the first base station and the ground terminal.

Optionally, before the first base station sends the first information, the first base station receives second information sent by the second base station, where the second information is used to request time information for allowing communication.

For example, assuming that the first base station is a PLMN base station (gNB), and the second base station is used to communicate with flight terminals, in this case, when the first base station has a higher priority communication service, if the first base station receives For the transmission time request information from the second base station, the first base station needs to notify the second base station of its occupation time information, so that the second base station is turned on and communicates during the time when the first base station is not occupied.

Optionally, in some embodiments, the above S210 may specifically be:

When the priority of the service corresponding to the first base station is lower than the priority of the service corresponding to the second base station, the first base station receives third information sent by the second base station; wherein the third information is used to indicate The first base station remains silent within the second duration, or the third information is used to indicate that the second base station occupies resources within the second duration;

The first base station keeps silent within the second duration according to the third information.

Optionally, the second duration is determined according to at least one of the following:

The service duration corresponding to the second base station, and the residence time of the equipment communicating with the second base station in the cell served by the second base station.

For example, assuming that the first base station is a PLMN base station, and the second base station is used to communicate with the flight terminal, in this case, the communication service between the flight terminal and the second base station has a higher priority. Then, when a flying terminal is about to enter the air cell where the second base station is located, the second base station obtains information such as the flight path and speed of the flying terminal, thereby obtaining information on the time when the flying terminal enters and leaves the air cell. During the time period corresponding to the time information (that is, the above-mentioned second time period), the second base station will remain on. In addition, the second base station notifies the first base station (such as gNB) in the adjacent area of the time period corresponding to the time information (that is, the second duration). After receiving the information, the first base station switches the ground terminals in the cell to other frequency points for work. Therefore, the first base station is kept silent at the communication frequency in the air, so as to avoid interference to the communication between the second base station and the flight terminal.

For another example, assuming that the first base station is used to communicate with the flight terminal, and the second base station is a PLMN base station, in this case, the communication service between the ground terminal and the second base station has a higher priority. Then, when a ground terminal is about to enter the cell where the second base station is located, the second base station can learn the time information when the ground terminal enters and leaves the cell where the second base station is located. During the time period corresponding to the time information (that is, the above-mentioned second time period), the second base station will remain on. In addition, the second base station notifies the first base station (such as a ground base station) in the adjacent area of the time period corresponding to the time information (that is, the first duration). After receiving the information, the first base station switches the flying terminals in the cell to other frequency points to work. Therefore, the first base station is kept silent at the communication frequency point where the second base station works, so as to avoid interference to the communication between the second base station and the ground terminal.

Optionally, before the first base station receives the third information sent by the second base station, the first base station sends fourth information to the second base station, where the fourth information is used to request time information for allowing communication.

Optionally, in some embodiments, the above S210 may specifically be:

The first base station sends request information to the second base station before communication, where the request information is used to request time-frequency resources;

The first base station receives the response information sent by the second base station, where the response information includes available time-frequency resources of the first base station, where the second base station keeps silent on the available time-frequency resources.

For example, assuming that the first base station is used to communicate with the flight terminal, and the second base station is a PLMN base station, before the first base station communicates with the flight terminal, it first requests the second base station (such as gNB) for some available time-frequency resources, and The second base station (such as gNB) locks the time-frequency resource when the flying terminal passes the air cell where the first base station is located. The second base station (such as gNB) allocates the remaining time-frequency resources to users in the cell. In this way, time-frequency resources do not overlap, and interference avoidance is realized.

Optionally, in some embodiments, the above S210 may specifically be:

The first base station monitors the time-frequency resource usage of the second base station before communication, and the first base station communicates using the time-frequency resource not occupied by the second base station.

Correspondingly, the second base station monitors the time-frequency resource usage of the first base station before communication, and the second base station uses time-frequency resources not occupied by the first base station for communication.

It should be noted that, in the embodiment of the present application, the above "quiet" may refer to standby, that is, no service transmission is performed. For example, the first base station keeping silent on the air communication frequency may mean that the first base station does not transmit services on the air communication frequency, or that the first base station does not use the air communication frequency to transmit services. For another example, the second base station keeps silent on the time-frequency resources available to the first base station, which may mean that the second base station does not perform service transmission on the time-frequency resources available to the first base station, or that the second base station does not use the first base station. The time-frequency resources available for the base station to transmit services. Other descriptions about "silence" in the embodiments of the present application are similar, and will not be explained one by one here.

Therefore, in the embodiment of the present application, the first base station avoids interference with the second base station by coordinating time-frequency resources with the second base station. That is, the first base station and the second base station adopt a time-division multiplexing manner in spectrum occupancy, thereby completely avoiding mutual interference.
