It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 3 is a schematic flowchart of an interference coordination method according to Embodiment 1 of the present invention. As shown in FIG. 3, the method includes: 301. The base station receives an interference coordination request sent by a neighboring cell base station, where the interference coordination request is sent by the neighboring cell base station to determine a to-be-coordinated signal beam from each of the signal beams transmitted by the neighboring cell.

 In practical applications, for a certain interference coordination interaction, the responder of the interference coordination and the responder of the interference coordination are usually included. The base station in this embodiment may be a responder in the interference coordination interaction. The signal beam to be coordinated may include a single signal beam transmitted by the neighboring cell base station, or may also include multiple signal beams transmitted by the neighboring cell base station.

 Specifically, the interference coordination request is that the neighboring cell base station uses, as each of the resource blocks (Resource Blocks, RBs), a signal beam that occupies the resource block as the to-be-coordinated signal beam. After sending. That is, the neighboring cell base station acquires an interference coordination request in units of signal beams corresponding to each RB, and performs interference coordination.

 In the above embodiment, more specifically, the interference coordination request may be a resource block in which the neighboring cell base station does not have neighboring cell interference in each of its resource blocks, and the signal beam occupying the resource block is used as a signal beam. The signal beam to be coordinated is transmitted after being transmitted. That is to say, the neighboring cell base station obtains an interference coordination request and performs interference coordination in units of signal beams corresponding to RBs in which no neighboring cell interference exists.

 Further, the Long Term Evolution (LTE) system is generally determined according to a narrowband transmit power (RNTP) indication, so that there is no neighboring cell. The interfering RB may specifically be an RB indicating that the RNTP is not indicated. Correspondingly, the interference coordination request may be: the resource block indicated by the neighboring cell base station for each of the resource blocks that are not indicated by the narrowband transmit power RNTP, and the signal beam occupying the resource block is used as the Transmitted after the coordinated signal beam is sent.

 In a practical application, the resource block is usually a time-frequency resource block, and the signal beam that occupies a resource block or a signal beam corresponding to a resource block is a signal beam that the base station transmits and transmits on the resource block. According to the present embodiment, comprehensive and reliable interference coordination can be performed in units of signal beams corresponding to each resource block. However, since the above embodiments need to perform interference coordination for signal beams corresponding to each RB, when the number of RBs is large, There may be a problem with a large overhead.

In this application, in the actual application, since the direction of the signal beams corresponding to the RBs allocated by the base station for a certain user equipment (User Equipment, UE for short) is the same, In addition to the interference coordination of the signal beams corresponding to the RBs, the interference can be coordinated by using the signal beams corresponding to the resource blocks allocated to each UE, that is, the signal beams allocated to each UE. Correspondingly, the interference coordination request may be that the neighboring cell base station sends, for each UE, a signal beam allocated to the UE as the signal beam to be coordinated.

 In an actual application, for the LTE system, the neighboring cell base station may send the interference coordination request to the base station by using an X2 interface.

The base station obtains, according to the interference coordination request, the area information of the to-be-coordinated silence zone corresponding to the to-be-coordinated signal beam, where the signal beam located in the to-coordinated silence zone will be the to-be-coordinated signal beam Cause interference.

 For example, if the second signal beam 26 in the figure is a signal beam to be coordinated, the area where the first signal beam 23 is located can be regarded as the corresponding to the second signal beam 26. Coordinate the quiet zone.

 Specifically, in the first implementation manner of the embodiment, the interference coordination request may include the to-be-coordinated The area information of the quiet zone, where the interference coordination request is sent by the neighboring cell base station after obtaining the area information of the to-be-coordinated silence zone. That is, in this embodiment, the area information of the to-be-coordinated silence area is obtained by the neighboring cell base station, and the base station may directly obtain the to-be-coordinated silence from the interference coordination request.

 Optionally, in a specific implementation manner of the first implementation manner, the neighboring cell base station obtains area information of the to-be-coordinated silence zone by calculation. Specifically, in the specific implementation manner, the interference coordination request is specifically that the neighboring cell base station is configured according to the acquired beam information of the to-be-coordinated signal beam and its own location information, Coordinating the signal beam, obtaining the beam width ΔΘ, and calculating the area information obtained by obtaining the quiet zone to be coordinated;

Where (θ' = θ - ΔΘ/2),

Θ is the horizontal angle of the signal beam to be coordinated.

 The beam width ΔΘ may be the width of the signal beam to be coordinated, or a preset value. In the actual implementation, the location information of the neighboring cell base station may be pre-stored in the neighboring cell base station; or the neighboring cell base station may pre-store its own location coordinates, coverage radius, and edge. The minimum radius of the area, in particular, the neighboring cell base station may acquire the location coordinates of the base station before transmitting the interference coordination request to the base station, and according to the location coordinates of the base station and the position coordinates of the base station Get its own location information. The neighboring cell base station acquires the location coordinates of the base station, and may be obtained by sending a query request to the base station and receiving a response returned by the base station including its location coordinates.

 Correspondingly, before 301, the method may further include: the base station receiving a query request sent by the neighboring cell base station; and the base station acquiring and returning its own location coordinates to the neighbor cell base station.

 The neighboring cell base station can accurately obtain the area information of the to-be-coordinated silence zone corresponding to the to-be-coordinated signal beam by using the foregoing specific implementation manner, so that the base station performs interference coordination according to the area information including the to-be-coordinated silence zone. The request enables fast and accurate interference coordination of the signal beam.

 Optionally, in another implementation manner of the first implementation manner, the neighboring cell base station may obtain the to-be-obtained area information by searching for a pre-stored signal beam corresponding to each of the signal beams. Coordinate the area information of the quiet zone. Specifically, the neighboring cell base station may perform measurement by using the base station, so as to obtain and store a rule that the base station transmits a signal beam in each area to interfere with a signal beam transmitted by the neighboring cell base station itself.

 Correspondingly, in the specific implementation, the interference coordination request is specifically: the neighboring cell base station searches for each of the currently stored signal beams transmitted by the neighboring cell base station for each of the to-be-coordinated signal beams. The beam information and the region information of the corresponding silence region are obtained, and the region information of the quiet region corresponding to the to-be-coordinated signal beam is obtained as the region information of the to-be-coordinated silence region;

The area information of the silence zone corresponding to the signal beam transmitted by the neighboring cell base station includes: The beam information of the interference beam transmitted by the base station and causing interference to the signal beam transmitted by the neighboring cell base station, where the silence zone is an area where the interference beam is located.

Includes:

 Receiving, by the base station, beam information of a signal beam sent by the neighboring cell base station, where beam information of the signal beam is sent by the neighboring cell base station after acquiring beam information of the signal beam that is transmitted by itself;

 Obtaining, by the base station, the beam information of the interference beam that is transmitted by the base station and causing interference to the signal beam transmitted by the neighboring cell base station by using the neighboring cell base station, so that the The neighboring cell base station stores the beam information of the interference beam to the area information of the quiet zone corresponding to the signal beam.

 The beam information of the signal beam sent by the neighboring cell base station to the base station and the signal beam is used to identify each signal beam. For example, the beam information may include the signal beam. The horizontal angle Θ, or may include the horizontal angle Θ and the pitch angle φ of the signal beam.

For example, it is assumed that the neighboring cell base station of the base station, ie, the base station, simultaneously schedules UE1 and UE2, and transmits a signal beam for UE1 to cover, and this! The horizontal and elevation angles of the beams are (θ "), φ ")) (i = l, ..., _ni ); for the UE2, n ₂ beams are transmitted for coverage, and the level of the n ₂ beams is set. The angle is (θ , φ ) (i = l, ..., n ₂ ); then the base station A transmits the beam information (θ "), φ ")) and (θ, φ) to the base station Β; After the above-mentioned beam information is transmitted by the base station, the area information of the corresponding quiet zone is obtained by measurement for each beam information and returned to the base station A for storage.

 According to the foregoing specific implementation manner, the neighboring cell base station can quickly and accurately obtain the area information of the to-be-coordinated silence zone corresponding to the to-be-coordinated signal beam, so that the base station interferes according to the area information including the to-be-coordinated silence zone. Coordination requests enable fast and accurate interference coordination of signal beams.

 In the above two specific implementation manners, the base station and the neighboring cell base station may use a line antenna or an area array antenna. Correspondingly, the deployment environment may be a direct path or a multipath component.

More specifically, in order to obtain the area information of the to-be-coordinated silence zone, to determine the to-be-determined Coordinating the quiet zone, in the second implementable embodiment of the present embodiment, the interference coordination request includes beam information of the to-be-coordinated signal beam, and the beam information includes a horizontal angle Θ, optionally, the The beam information may also include a pitch angle φ. Correspondingly, in this embodiment, the method for obtaining, by the base station, the area information of the quiet zone to be coordinated according to the interference coordination request may also be implemented in various specific manners.

An angle θ ₂ , the to-be-coordinated silence zone is an area between 0i and 0 ₂ with respect to an azimuth of the base station;

 Similarly, in the actual implementation, the location information of the neighboring cell base station may be pre-stored in the base station; or the base station may store its own location coordinates in advance, and correspondingly, before 301 The base station may first acquire location coordinates, a coverage radius, and a minimum radius of the edge region of the neighboring cell base station, and obtain location information of the neighboring cell base station according to the foregoing information and its own location coordinates. The base station acquires the location coordinates, the coverage radius, and the minimum radius of the edge region of the neighboring cell base station, where the information may be sent by sending the query request to the neighboring cell base station and receiving the information returned by the neighboring cell base station. The response is obtained.

For a better understanding of the technical solution of this embodiment, based on the specific implementation example, it is assumed that the neighboring cell base station of the base station, ie, the base station, simultaneously schedules UE1 and UE2, and transmits for UE1! ^ signal beams are covered, and the horizontal angle of the _ηι signal beams is θ) (i=l,..., _ni ), and n ₂ signal beams are transmitted for UE2 to cover, and n ₂ The horizontal angle of the signal beam is Θ ) ( i = l, ..., n ₂ ), then the base station A uses the signal beam corresponding to UE 1 and UE 2 as the signal beam to be coordinated, and will include interference of θ ") and θ ) After the coordination request is sent to the base station, the base station receives the interference coordination request and performs the following processing:

For each signal beam corresponding to UE 1, the azimuth angle relative to the base station 在 is J _y 〜 J _{i; 2} ( i = l , . . . , _ni ) ^ The area range is its corresponding silent area to be coordinated. among them,

For each signal beam corresponding to UE2, the azimuth angle with respect to base station B is Ji, 2 l, ..., n ₂ ). The n ₂ area ranges are the corresponding silent regions to be coordinated. among them,

J! i = tan,

Schematic diagram of the area to be coordinated in the silence zone. As shown in FIG. 4, it is assumed that the signal beam 41 transmitted by the base station to the UE in the figure is the signal beam to be coordinated, and the coverage radius of the base station A is r ₂ , and the minimum radius of the edge area of the base station A. For the distance R between the base station A and the base station B and the azimuth angle of the base station A relative to the base station B, the corresponding first azimuth angle and second azimuth angle θ _{2 are} obtained by calculation according to the foregoing method. As shown in the figure, the azimuth angle with respect to the base station 在 is in the region 42 between θ ₂ and the silence region corresponding to the signal beam 41 to be coordinated.

 It should be noted that the shaded portions in the respective drawings of the present embodiment can be used to roughly determine the orientation information of the transmitted signal beam, which does not limit the actual area size such as the transmission distance and width of the signal beam. For example, in an actual application, the coverage of the signal beam may continue to extend along the direction of the beam determined in the figure, which is not limited in this embodiment.

Before the beam information and the corresponding region information of the silent region, the method may further include:
