The first network device determines, according to the transmit power of the second device, the transmission loss value between the second device and the third network device, and the receiving antenna gain of the third network device, the corresponding value of the third network device. The received power of the interfering signal.

Wherein, after the first network device determines the transmit power of the second device, the transmission loss value between the second device and the third network device, and the receive antenna gain of the third network device, the formula (7 ) is calculated to obtain the received power of the interference signal corresponding to the third network device:

l=P-L+G (7)

Among them, l is the received power of the interference signal corresponding to the third network device, P is the transmit power of the second device, L is the transmission loss value between the second device and the third network device, and G is the first The receive antenna gain of the three network devices.

S308: The first network device selects, from at least one third network device, a third network device whose received power of the interference signal is greater than a preset power threshold as the target network device.

In this step, after the first network device obtains the received power of the interference signal corresponding to each third network device in the at least one third network device, it can obtain the received power of the interference signal from the network management device, the network server or the memory of the first network device. to obtain the preconfigured preset power threshold. The preset power threshold may be determined according to the influence of the received power of the interference signal on the third network device, and may be configured as -90dBm, for example. Further, after acquiring the pre-configured preset power threshold, the first network device may compare the received power of the interference signal corresponding to each third network device in at least one third network device with the preset power threshold. , using the third network device whose received power of the interference signal is greater than the preset power threshold as the target network device, and the received power of the interference signal corresponding to the third network device whose received power of the interference signal is greater than the preset power threshold, As the received power of the interference signal corresponding to the target network device.

The received power of the interference signal corresponding to the target network device sends resource allocation information to the target network device.

S310. The target network device adjusts resource allocation according to the resource allocation information sent by the first network device.

In this step, after the target network device receives the resource allocation information sent by the first network device, the resource allocation can be adjusted according to a preset adjustment policy. In a possible implementation manner, the target network device may set the target resource block to be prohibited from being used within the use time, that is, the target network device does not use the target resource block within the time when the second device uses the target resource block. Then use the corresponding target resource block in the target network device. In this way, the target network device will not be interfered by the signal of the second device.

In a second possible implementation manner, the target network device may set the target resource block to be used at a limit within the usage time, and adjust the modulation and coding mode of the terminal scheduling the target resource block according to the received power of the interference signal. Here, the target network device may determine the level of the adjusted modulation and coding scheme according to the coding scheme correlation in Table 1 and the received power of the interference signal. For example, if the anti-interference strength needs to be increased by 5dB, the current signal-to-noise ratio can be reduced by 5dB, and then the adjusted modulation and coding mode is determined according to the reduced signal-to-noise ratio. For example, if the modulation and coding mode of the terminal scheduling the target resource block is 64QAM 3/4 coding, the signal-to-noise ratio threshold corresponding to this modulation and coding mode is 12dB, and the anti-interference strength needs to be increased by 5dB, then the adjusted signal-to-noise ratio is 7dB, and then it can be determined that the adjusted modulation and coding mode is 16QAM 3/4 coding. In this way, after the level of the modulation and coding scheme of the terminal that schedules the target resource block is lowered, the corresponding demodulation signal-to-noise ratio threshold is also lowered. When the strength of the useful signal remains unchanged, it can withstand stronger interference signals, so that the The target network device will not be interfered by the signal of the second device.

In a third possible implementation manner, the target network device may set the target resource block to be used at a limit within the usage time, and adjust the transmit power of the terminal scheduling the target resource block according to the received power of the interference signal. Wherein, the target network device can be preset according to the signal-to-noise ratio threshold corresponding to the modulation and coding method, the interference value in the system, and the received power of the interference signal. The interference value in the system can be preset, and the adjusted The transmit power of the terminal:

P _T =SNR*(I _intra +l) (8)

Wherein, P _T is the adjusted transmit power of the terminal, SNR is the signal-to-noise ratio threshold corresponding to the modulation and coding scheme, I _intra is the intra-system interference value, and l is the received power of the interference signal.

In this way, the target network device increases the power of the useful signal by adjusting the transmit power of the terminal that schedules the target resource block, so that the target network device will not be interfered by the signal of the second device.

Using the above method, the target network device can set the target resource block to be prohibited from being used within the usage time according to the resource block information of the target resource block currently occupied by the second device and the received power of the interference signal corresponding to the target network device, or set the target Set the resource block to limit usage within the usage time, and adjust the modulation and coding method of the terminal that schedules the target resource block, or set the target resource block to limit usage within the usage time, and adjust the transmission of the terminal that schedules the target resource block power.
