Embodiment 1

[0088] Embodiment 1: Taking the first network device as the gNB-CU of the access network and device in the interfered area, and the second network device as the gNB-DU connected to the gNB-CU as an example, the remote interference management process can be as follows Figure 7 shown.

[0089] S701, the gNB-DU determines that there is long-range interference.

[0090] In some embodiments, if the gNB-DU is a gNB-DU in the interfered area, the gNB-DU may determine that there is long-range interference when it is determined that long-range interference is received.

[0091] In some other embodiments, if the gNB-DU is the gNB-DU in the interference source area, the gNB-DU may determine that there is long-range interference when receiving the RS sent by the network equipment in the interfered area. Exemplarily, the RS sent by the network equipment in the interfered area may be a reference signal marked as RS-1.

[0092] S702. The gNB-DU sends an interference intensity indication t...

Embodiment 2

[0108] Embodiment 2: Taking the first network device as the gNB-CU in the interfered area and the second network device as the gNB-DU connected to the gNB-CU as an example, the remote interference management process can be as follows Figure 8 shown.

[0109] S801, for details, refer to S701, which will not be repeated here.

[0110] S802. The gNB-DU sends the first information to the gNB-CU.

[0111] In a specific implementation, when the gNB-DU sends the first information to the gNB-CU, it may also send second information to the gNB-CU, where the second information is used to indicate the RS configuration information preferentially selected by the second network device. Wherein, the second information may be specific RS configuration information, for example, the second information is second RS configuration information, and the second RS configuration information may include at least one of the following information: RS sending time, RS The transmission cycle of the RS, t...

Embodiment 3

[0117] Embodiment 3: Taking the first network device as AMF and the second network device as gNB as an example, the process of remote interference management can be referred to Figure 7 or Figure 8 shown, and will not be repeated here. It should be noted that the execution subject of Embodiment 3 is not the same as that of Embodiment 1 and Embodiment 2. Specifically, the actions performed by the gNB-CU in Embodiment 1 and Embodiment 2 are executed by the AMF in Embodiment 3. To execute, the actions performed by the gNB-DU in Embodiment 1 and Embodiment 2 are executed by the gNB in ​​Embodiment 3.

[0118] Compared with the prior art where the RS is configured by the OAM, the stop of the RS transmission, the triggering and stopping of the RS monitoring, and the triggering and stopping of the application of the remote interference suppression solution all depend on the manual intervention of the OAM. In the embodiment of the present application, configuring RS transmission t...

The method includes: the first network device receives first information sent by the second network device, the first information is used to request configuration information of a reference signal RS, and the RS is used to indicate that the second network device is subject to remote interference , the first network device is a centralized unit, and the second network device is a distribution unit; or, the first network device is a core network device, and the second network device is an access network device; the first network device is a core network device, and the second network device is an access network device; The network device sends the first RS configuration information to the second network device.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a remote interference management method and device. Background technique [0002] Under special atmospheric conditions, the electromagnetic waves propagating in the atmosphere are affected by the refraction of the atmosphere, and their propagation paths are bent to the ground. When the curvature exceeds the curvature of the earth's surface, the electromagnetic waves will be partially trapped in a thin layer of the atmosphere with a certain thickness. Like electromagnetic waves propagating in a waveguide, this phenomenon is called the atmospheric waveguide phenomenon. However, due to the existence of the atmospheric ducting phenomenon, the downlink signal sent by the base station in area A may propagate to area B. Among them, the distance between area B and area A can reach 300 kilometers. If the base station in area B is performing uplink transmission, the ...
