The downtilt angle of 1 (an example of the first downtilt angle) and/or the downtilt angle of the carrier 2 (an example of the second downtilt angle).

Here, it should be noted that, in the embodiment of the present invention, the downtilt angle refers to the tilt angle of the beam direction of the carrier in the vertical direction, and the downtilt angle may be a mechanical form, or may be a digital form, a digital form. The downtilt angle is defined as the angle between the strongest energy direction on the vertical plane and the vertical line. For example, the downtilt angle of carrier 1 used by base station device A shown in Fig. 3 is the downtilt angle of carrier 2 used by base station equipment.

It should be understood that the term "and/or" in this context is merely an association describing the associated object, indicating that there may be three relationships, for example, A and / or B, which may indicate: A exists separately, and A and B exist simultaneously.

As shown in FIG. 3, the beam directions of carrier 1 and carrier 2 used by the base station device B can be set such that the downtilt angle α ₂ (third downtilt angle) of the carrier 1 is the same as the downtilt angle β ₂ (fourth downtilt angle) of the carrier 2, Thereby, the coverage of the carrier 1 from the base station device 与 is made the same as the coverage of the carrier 2 from the base station device 。. For example, FIG. 3 shows the coverage of the carrier 2 from the base station device 与 and the carrier from the base station device Α An embodiment in which the coverage of the coverage overlaps. Moreover, in the embodiment of the present invention, the coverage of the carrier 2 from the base station device B and the coverage of the carrier 2 from the base station device A can be made in the same manner as in the prior art. Range overlap On carrier 2 in order to achieve continuous coverage of the area between the base station apparatus A and base station apparatus B Hereinafter, description of the same or similar circumstances will be omitted.

If the coverage area of the carrier 2 from the base station device A and the boundary area (or the overlapping area) of the coverage of the carrier 2 from the base station device B are recorded as the area a, the coverage with the carrier 1 from the base station device A will be covered. The area outside the coverage of the carrier 1 from the base station apparatus B is denoted as the area b, and in the area a, since the interference from the carrier 1 of the base station apparatus A is small, the signal quality of the carrier 1 from the base station apparatus B is excellent. Letter from carrier 2 of base station device B No. Quality, therefore, the user equipment can select carrier 1 access. In area b, carrier 2 from base station device A can be covered, so the user equipment can select carrier 2 access.

It should be understood that the manner of setting the carrier beam enumerated above is only an exemplary description, and the present invention is not limited thereto. For example, the coverage of carrier 1 from the base station device B and the carrier 1 from the base station device A may also be used. The coverage overlaps the implementation to achieve continuous coverage of the area between base station device A and base station device B on carrier 1.

Optionally, in the embodiment of the present invention, the third downtilt angle is different from the fourth downtilt angle, wherein the third downtilt angle is a tilt of a beam direction of the first carrier used by the second base station device in a vertical direction. Angle, the fourth downtilt angle is an inclination angle of a beam direction of the second carrier used by the second base station device in a vertical direction.

Specifically, for example, as shown in FIG. 4, the beam direction of carrier 1 and/or carrier 2 used by base station apparatus A can be set such that the downtilt angle α Ί (first downtilt angle) of carrier 1 and the downtilt angle β of carrier 2 Ί (the second downtilt angle) is different (for example, making the downtilt angle of carrier 1 smaller than the downtilt angle βΊ of carrier 2), thereby making the coverage of carrier 1 from the base station device 小于 smaller than the coverage of carrier 2 from base station device A .

In addition, as shown in FIG. 4, the beam direction of carrier 1 and carrier 2 used by the base station device B can be set such that the downtilt angle α, ₂ (third downtilt angle) of the carrier 1 and the downtilt angle β, _{2 of the} carrier 2 The four downtilt angles are different (for example, the downtilt angle α, _{2 of} the carrier 1 is greater than the downtilt angle β, _{2 of the} carrier 2), thereby making the coverage of the carrier 1 from the base station device 大于 larger than the carrier 2 from the base station device 2 Coverage.

Thus, in the region c, since the interference energy of the carrier 2 from the base station device B is weak (distance from the radiation center point of the carrier 2 of the base station B), And the useful signal energy of the carrier 2 from the base station device A is stronger (closer to the radiation center point of the carrier 2 of the base station A), so the signal quality of the carrier 2 from the base station device A is better than the signal quality of the carrier 1, and the user equipment can Select carrier 2 access. Similarly, in region d, the signal quality of carrier 1 is better than the signal quality of carrier 2, and the user equipment can select carrier 1 access.

For another example, as shown in FIG. 5, the beam direction of carrier 1 and/or carrier 2 used by base station device A may be set such that the downtilt angle α, Ί (first downtilt angle) of carrier 1 and the downtilt angle β of carrier 2, Ί (the second downtilt angle) is different (for example, making the downtilt angle a of carrier 1 smaller than the downtilt angle β' of carrier 2), thereby making the coverage of carrier 1 from the base station device 小于 smaller than the carrier from base station device A 2 coverage.

In addition, as shown in FIG. 5, the beam directions of carrier 1 and carrier 2 used by the base station device B can be set such that the downtilt angle α, ₂ (third downtilt angle) of the carrier 1 and the downtilt angle β of the carrier 2, ₂ (fourth downtilt angle) is different (for example, the downtilt angle α" _{2 of} carrier 1 is smaller than the downtilt angle β" _{2 of} carrier ₂ ), thereby making the coverage of carrier 1 from the base station device 小于 smaller than that from the base station device Β The coverage of carrier 2.

If the coverage area of the carrier 2 from the base station device A and the boundary area (or the overlapping area) of the coverage of the carrier 2 from the base station device B are recorded as the area a, the coverage with the carrier 1 from the base station device A will be covered. The area outside the coverage of the carrier 1 from the base station apparatus B is denoted as the area b, and in the area a, since the interference from the carrier 1 of the base station apparatus A is small, the signal quality of the carrier 1 from the base station apparatus B is excellent. The signal quality of carrier 2 from base station device B, therefore, the user equipment can select carrier 1 access. In area b, carrier 2 from base station device A can be covered, so the user equipment can select carrier 2 access.

Coverage.

If the coverage area of the carrier 1 from the base station device A and the boundary area (or overlapping area) of the coverage of the carrier 1 from the base station device B are recorded as the area c, the coverage with the carrier 2 from the base station device A will be The boundary area between the range and the coverage of the carrier 2 from the base station device B is referred to as the area d, and the position of the area c and the area d is different. Therefore, in the area c, the interference energy of the carrier 2 from the base station apparatus B is weak (the radiation center point of the carrier 2 away from the base station B), and the useful signal energy of the carrier 2 from the base station apparatus A is stronger (closer to the base station) The radiation center point of carrier 2 of A, so the signal quality of carrier 2 from base station equipment A is better than the signal quality of carrier 1, and the user equipment can select carrier 2 access. Similarly, in area d, the signal quality of carrier 1 is better than the signal quality of carrier 2, and the user equipment can select carrier 1 to access.

For another example, as shown in FIG. 5, the control center may set the beam direction of carrier 1 and/or carrier 2 used by base station device A to make the downtilt angle α, Ί (first downtilt angle) of carrier 1 and the downtilt angle of carrier 2. β'Ί (second downtilt angle) is different (for example, making the downtilt angle a of carrier 1 smaller than the downtilt angle β' of carrier 2), thereby making the coverage of carrier 1 from the base station device 小于 smaller than that from the base station The coverage of carrier 2 of device A.

For example, FIG. 5 shows an embodiment in which the coverage of the carrier 2 from the base station device 交 overlaps with the coverage of the carrier 2 from the base station device ,, thereby implementing the connection between the base station device A and the base station device B on the carrier 2.

The signal strength is such that the user equipment concentrated in the coverage area of the carrier 1 selects the carrier 1 access, and the capacity of the carrier 2 that can be used for the user equipment located outside the coverage of the carrier 1 is improved, thereby further improving the user experience.

As described above, after determining the beam direction of the carrier 1 and/or the carrier 2 used by the base station A, the control center may send information (first configuration information) indicating the beam direction of the carrier 1 and/or the carrier 2 to the base station A, Therefore, the base station A can set the beam direction of the carrier 1 and/or the carrier 2 according to the information, for example, setting the mechanical angle of the antenna of the carrier 1 and/or the antenna of the carrier 2, the electrical adjustment angle, etc., so that the carrier 1 and/or The beam direction of carrier 2 corresponds to the first configuration information.

Similarly, the control center The same method may be used to determine the beam direction of the carrier 1 and/or the carrier 2 used by the base station B, and to send an information indicating the beam direction of the carrier 1 and/or the carrier 2 to the base station B. Here, in order to avoid redundancy, The description is omitted.

After setting the beam direction of carrier 1 and/or carrier 2 as described above, base station A can communicate with the user equipment through the carrier 1 and carrier 2 at S120.

In the above, enumeration is made by overlapping carrier 1 from base station A with carrier 1 from base station B, and/or overlapping carrier 2 from base station A with carrier 2 from base station B, thereby implementing base station A and base station B. Embodiments in which the area between the areas is continuously covered, but the present invention is not limited thereto. For example, carrier 1 from base station A may be overlapped with carrier 2 from base station B, and/or carrier from base station A may be made. 2 overlaps carrier 1 from base station B, thereby achieving continuous coverage of the area between base station A and base station B.

According to the method of multi-carrier communication according to the embodiment of the present invention, different carriers used by the station device have different coverage ranges by setting different downtilt angles for different carriers, and thus, in the multi-carrier communication system, different The carrier carrier is different in the edge boundary area between the base station devices, so that different carriers provide differentiated coverage for different regions, and users in different regions are more suitable for carrier transmission according to the difference, thereby improving overall performance.

The downtilt angle is defined as the direction of the strongest energy in the vertical plane. For example, the downtilt angle of carrier 1 used by base station device A shown in Fig. 2 is the downtilt angle of carrier 2 used by base station device A.

Therefore, in the embodiment of the present invention, for example, in a case where the beam direction of the carrier 2 is preset, only the beam direction of the carrier 1 may be set; the beam direction of the carrier 1 is preset. In this case, only the beam direction of the carrier 2 can be set; the beam directions of the carrier 1 and the carrier 2 can also be set together.

For example, Figure 3 shows the coverage of carrier 2 from the base station equipment and the base station equipment.

An embodiment in which the coverage of the carrier 2 of the 交 overlaps. Moreover, in the embodiment of the present invention, the coverage of the carrier 2 from the base station device B can be overlapped with the coverage of the carrier 2 from the base station device A by using the same method as the prior art, thereby implementing on the carrier 2. Continuous coverage of the area between base station device A and base station device B. Hereinafter, the description of the same or similar cases will be omitted.

If the coverage area of the carrier 2 from the base station device A and the boundary area (or the overlapping area) of the coverage of the carrier 2 from the base station device B are recorded as the area a, the coverage with the carrier 1 from the base station device A will be covered. The area outside the coverage of the carrier 1 from the base station apparatus B is denoted as the area b, and in the area a, since the interference from the carrier 1 of the base station apparatus A is small, the signal quality of the carrier 1 from the base station apparatus B is excellent. The signal quality of carrier 2 from base station device B, therefore, the user equipment can select carrier 1 access. In area b, carrier 2 from base station device A can be covered, so the user equipment can select carrier 2 access. It should be understood that the manner of setting the carrier beam enumerated above is only an exemplary description, and the present invention is not limited thereto. For example, the coverage of carrier 1 from the base station device B and the carrier 1 from the base station device A may also be used. The coverage overlaps the implementation to achieve continuous coverage of the area between base station device A and base station device B on carrier 1.

Optionally, in the embodiment of the present invention, the control center in the multi-carrier communication system determines a beam direction of the first carrier and/or the second carrier of the at least two carriers used by the first base station device, and the second base station device The beam direction of the first carrier and/or the second carrier used includes:

A control center in the multi-carrier communication system determines a beam direction of a first carrier and/or a second carrier of the at least two carriers used by the first base station device, and the first carrier and/or the second used by the second base station device a beam direction of the carrier, such that the third downtilt angle is different from the fourth downtilt angle, wherein the third downtilt angle is a tilt angle of a beam direction of the first carrier used by the second base station device in a vertical direction, the first The four downtilt angle is an inclination angle of the beam direction of the second carrier used by the second base station device in the vertical direction.

Specifically, for example, as shown in FIG. 4, the control center may set the beam direction of carrier 1 and/or carrier 2 used by the base station device A to make the downtilt angle α Ί (first downtilt angle) of the carrier 1 and the carrier 2 The tilt angle βΊ (the second downtilt angle) is different (for example, the downtilt angle of the carrier 1 is smaller than the downtilt angle βΊ of the carrier 2), so that the coverage of the carrier 1 from the base station device Α is smaller than that of the carrier 2 from the base station device A. Coverage.

If the coverage area of the carrier 1 from the base station device A and the boundary area (or the overlapping area) of the coverage of the carrier 1 from the base station device B are recorded as the area c, The boundary area of the carrier 2 of the standby A and the boundary area of the coverage of the carrier 2 from the base station apparatus B are referred to as the area d, and the positions of the area c and the area d are different. Therefore, in the area c, the interference energy of the carrier 2 from the base station apparatus B is weak (the radiation center point of the carrier 2 away from the base station B), and the useful signal energy of the carrier 2 from the base station apparatus A is stronger (closer to the base station) The radiation center point of carrier 2 of A, so the signal quality of carrier 2 from base station equipment A is better than the signal quality of carrier 1, and the user equipment can select carrier 2 access. Similarly, in region d, the signal quality of carrier 1 is better than the signal quality of carrier 2, and the user equipment can select carrier 1 access.

If the coverage of carrier 1 from base station device A and the area outside the coverage of carrier 1 from base station device B are denoted as region e, the coverage with carrier 2 from base station device A and the carrier from base station device B The boundary area of the coverage area of 2 (or the overlap area) is denoted as area f, then in area e, so the signal quality of carrier 2 from base station device A or base station device B is better than the signal quality of carrier 1, user equipment Carrier 2 access can be selected.

The control center in the multi-carrier communication system receives the first user location information sent by the first base station device to indicate the location of the at least one user equipment in the multi-carrier communication system and/or the second base station device sends Used to indicate that the at least one user equipment is in the multi-carrier communication system Second user location information of the location in the system;

The signal strength, therefore, the user equipment that is in the coverage of the carrier 1 and the carrier 2 will select the carrier 1 access, so that the capacity of the carrier 2 that can be used is improved for the user equipment located outside the coverage of the carrier 1 ( That is, carrier 1 implements offloading on carrier 2, thereby further improving the user experience. Therefore, in the embodiment of the present invention, the distribution location of the user equipment in the system may be determined, and the coverage of the carrier 1 and the carrier 2 may be determined according to the distribution location of the user equipment in the system, for example, the coverage user of the carrier 1 may be The area where the device is concentrated is such that the coverage of the carrier 2 is larger than the coverage of the carrier 1.
