The technical scheme of the invention is further described by combining the specific embodiments as follows:
the first embodiment is as follows: different cells configure reference signals at different locations (areas of SSB set to 0). The reference signal in this embodiment is specifically a demodulation reference signal DM-RS, however, the reference signal in this embodiment is not limited to be a DM-RS, and may also be another type of reference signal.
In the SSB set to 0 region, positions of 0 symbol0,1, …,55,183,184, …,239 and 48,49, …,55,183,184, …,191, total 128 REs (Resource Element) can be used to configure a reference signal DM-RS, and maximum 128 configurable cells transmit DM-RS reference signals on different REs for acquiring interference in the local region.
In this embodiment, the respective interference values of all neighboring cells may be obtained through SSB, and the reference signal received powers of all RE positions are summed to obtain the neighboring cell interference power of the cell, where the reference signal received power is RSRP.
Further, reference signals can be configured in a CELL _ ID modulo N manner, for example, the reference signals are sent at RE positions corresponding to CELL _ ID modulo three or modulo four, at this time, the reference signal interference sent by the neighboring CELL at the same position accounts for the local area received useful power, and the reference signal received powers at other positions are summed to be the neighboring CELL interference power. Wherein, CELL _ ID is a CELL identification code, and N is a natural number.
Example two: different cells configure reference signals in the same location (area of SSB set to 0) while configuring the quiet period. The reference signal in this embodiment is specifically a demodulation reference signal DM-RS, however, the reference signal in this embodiment is not limited to be a DM-RS, and may be other types of reference signals.
The network configures a silent period of each cell, and the cell does not send a reference signal in the silent period, so that the reference signal received power measured at the position where the reference signal is configured is the interference of the neighboring cell.
Compared with the first embodiment, the second embodiment has less resource occupancy rate and only occupies a small number of positions to transmit the reference signals.
Example three: different cells configure reference signals at the same position (SSB set to 0 area), and after the position measurement of the configured reference signals obtains the reference signal received power, the RSRP obtained by the auxiliary synchronization signals SSS is subtracted, so that the interference of the adjacent cell can be obtained through calculation and used for calculating the SINR, wherein the reference signal received power is the total power. The reference signal in this embodiment is specifically a demodulation reference signal DM-RS, however, the reference signal in this embodiment is not limited to be a DM-RS, and may be other types of reference signals.
Compared with the first embodiment and the second embodiment, in the third embodiment, the reference signal occupies a lower resource, and does not need to configure a quiet period, and the measurement is accurate.
In the technical scheme of the invention, the reference signal is configured in the spare area of the SSB to obtain the interference of the SSB adjacent cell, which is used for calculating the SSB SINR and is suitable for the judgment of mobility management.
