Description
Technical Field
The present invention relates to wireless communication technologies, and in particular, to a reference signal resource allocation method, a network device, and a storage medium.
Background
In a Time Division Duplex (TDD) system, due to the existence of the atmospheric waveguide phenomenon, a downlink signal of a base station (interfering station) may interfere with an uplink signal of a remote base station (interfered station). Such Interference may occur at two base stations that are several hundred kilometers away, causing the Interference over Thermal (IoT) of the victim station to increase, and seriously affecting the uplink signal reception quality of the victim station. In order to eliminate the interference, the interfering station and the distance between the interfering station and the interfered station need to be firstly identified, and corresponding backspacing is carried out.
At present, a reference signal is sent at a fixed downlink transmission position by a victim station, and an aggressor station detects the reference signal at a corresponding uplink symbol, and then judges that the interference is caused to the corresponding uplink symbol of the victim station according to a known downlink sending position and an uplink receiving position, so that the corresponding symbol number needs to be backed off at the aggressor station to avoid the interference to the victim station.
However, in a Time Division Long Term Evolution (TD-LTE) system, the shortest uplink and downlink switching period is 5 milliseconds (ms), and at least one uplink subframe is 1ms in length, which means that at least a base station 300 kilometers (km) away can be identified. However, in the New Radio (NR) system, the uplink and downlink switching period is shortened, which may be only 2ms, 2.5ms or even shorter, which results in the absolute duration of the uplink being shortened. If a reference signal is continuously transmitted along a fixed downlink transmission position, the transmitted reference signal may fall on a downlink symbol of the next period of the interfering station after being propagated through the atmospheric waveguide due to too short uplink time, that is, the reference signal cannot be detected in the period, so that the interference cancellation effect is greatly affected.
