Embodiment Construction
[0070] The main problem of related schemes is that the fixed initial phase set of reference signals is vulnerable to malicious attacks, resulting in a severe degradation of the DL transmission performance of the entire network.
[0071] For example, when the atmospheric ducting phenomenon does not occur, the attacker actively sends a dedicated RS for remote interference detection, and its initial phase is selected from the preset initial phase set. When other base stations in the network detect the RS, they may mistakenly judge that they are the interfering station of a certain base station, and then perform an interference fallback operation. When a large number of base stations in the network perform interference backoff operations, the downlink throughput of the entire network will be seriously reduced.
[0072] 5G NR systems generally use time-division duplexing, so they will also suffer from far-end interference problems. In order to solve the far-end interference proble...
