S1, RAN a (i.e. the first device) sends an interference measurement request and radio configuration information (i.e. first radio configuration information) of cell a, including a radio configuration identifier (e.g. target radio identifier) and a frame structure (e.g. first frame structure information) to RAN B (i.e. the second device). The radio configuration identifier (e.g., target radio identifier) is used to distinguish between radio configurations, and is changed when the frame structure (e.g., first frame structure information), default beam or antenna tilt angle, etc. are changed.
S2, the RAN B (i.e. the second device) compares the frame structure information of the cells A and B (i.e. compares the first frame structure information and the second frame structure information) and identifies the interference direction and the interfered time-frequency resource.
S3a, according to the result of S2, if there is a possibility of cross interference between the cells a and B, the RAN B (i.e. the second device) may send an interference measurement acceptance request and radio configuration information (i.e. the second radio configuration information) of the cell B to the RAN a (i.e. the first device).
S3ba, RAN B (i.e. the second device) may also send a reject interference measurement request to RAN a (i.e. the first device) because the cell a and B frame structures are the same (i.e. the structure of the first frame structure information and the second frame structure information are the same), or RAN B does not support the cross interference measurement function, etc.
Optionally, the device to which the interfering cell belongs (i.e. the first device) sets a reference signal (e.g. a target measurement signal) on each transmit beam. The device to which the disturbed cell belongs (i.e. the second device) performs measurements based on a reference signal, such as a target measurement signal.

S4, the RAN A (i.e. the first device) compares the frame structure information of the cells A and B (i.e. compares the first frame structure information and the second frame structure information) and identifies the interference direction and the interfered time-frequency resource.
S5, the RAN A (i.e. the first device) sends the beam and the reference signal information (such as target measurement signals) related to the cross interference measurement of the cell A to the RAN B (i.e. the second device), wherein the information comprises the identifier of the beam, the identifier of the reference signal, the association relation between the beam and the reference signal, the time-frequency resource sent by the reference signal, the sequence of the reference signal, the power of the reference signal and the like.
It should be noted that, the beam and the reference signal may be shared by the configured beam and the reference signal (e.g., the beam sent to a terminal and the corresponding CSI-RS or DMRS, etc.), or the beam and the reference signal may be newly configured for interference measurement.
S6a, the RAN B (i.e. the second device) acknowledges to the RAN a (i.e. the first device) that the beam and the reference signal (i.e. the target measurement signal) can be measured.
S6B, if necessary, RAN B (i.e. the second device) indicates to RAN a (i.e. the first device) to abort the measurement (which may also be sent at other occasions).
S7, as described in S5, cell a (i.e. the first device) may transmit the corresponding beam and reference signal (i.e. the target measurement signal).
S8, according to the reference signal (namely the target measurement signal) received by the cell B (namely the second equipment), analyzing and recording the path loss of each wave beam, including the size, the fluctuation condition and the like, and the change of the path loss with time or frequency. If necessary, the beam of interest is picked for further measurement.
Optionally, the device to which the interfered cell belongs (i.e. the second device) picks a transmitting beam of interest (i.e. picks a target measurement signal), adjusts a receiving beam, and identifies the interference condition of the beam pair.
Fig. 4B is a schematic diagram of a precise procedure of cross interference according to an embodiment of the present invention, as shown in fig. 4B, taking as an example the measurement of cross interference generated by a cell a (i.e. a first device) to a cell B (i.e. a second device), the procedure includes:
S9, RAN B (i.e. the second device) provides the list of beams of interest (i.e. the list of target measurement signals) to RAN a (i.e. the first device).
S10, based on the list (i.e. the target measurement signal list), RAN a (i.e. the first device) updates the beam and the reference signal (i.e. the target measurement signal) of cell a and sends corresponding information to RAN B (i.e. the second device).
S11, the RAN B (i.e. the second device) acknowledges to the RAN a (i.e. the first device) that the beam and the reference signal (i.e. the target measurement signal) can be measured.
S12, as described in S10, the cell a (i.e. the first device) transmits the corresponding beam and the reference signal (i.e. the target measurement signal).
S13, analyzing and recording the path loss of each transmitting-receiving beam pair according to the reference signal received by the cell B (namely the second device).
Optionally, the device to which the interfered cell belongs (i.e. the second device) reports the interference situation of each beam to the device to which the interfering cell belongs (the first device).

The above embodiments of the present invention enable one cell to be both a scrambling cell and a scrambling cell by a flexible frame structure. Thus the coarse measurement, fine measurement, interference reporting procedure may be opposite to the message direction of the example, or the two directions may be superimposed to measure the mutual cross interference at the same time.
As an alternative embodiment, since the radio configuration information is directly related to the interference situation, the record stores the interference measurement result, and also contains the corresponding radio configuration identifier (i.e. the target radio identifier).
Optionally, if the device interfering with the cell (i.e. the first device) has several radio configurations, one of them is selected according to the current service requirement. When changing the radio configuration, the device (i.e. the second device) of the interfered cell is informed of the new radio configuration identifier, and if the device (i.e. the second device) of the interfered cell measures the interference condition of the configuration, the interference condition can be known in time under the condition of not measuring.
Alternatively, if the interference measurement result is significantly changed under the same radio configuration, it is likely that the external environment is changed, and thus the interference of other neighboring cells may also be changed, which may be used as a basis for triggering the interference measurement request.
Alternatively, depending on the measurement results in the interfered cell (i.e., the second device), the Shi Rao cell (i.e., the first device) may use the low-interference transmit beam or reduce the transmit power as much as possible on the time-frequency resources that generate the interference.
Optionally, the device involved in the interfered cell (i.e. the second device) can recognize the interference condition of the transmitting beam, and also know the interference condition of each receiving beam under the specific transmitting beam, and in order to reduce the interference, the receiving beam with low interference can be used on the interfered time-frequency resource as much as possible.
Compared with the prior art, the technical scheme provided by the application can sense the condition of changing the wireless configuration of the adjacent cell, is convenient for long-term interference management, realizes the interference measurement of the beam pair level, and assists Shi Rao in carrying out interference coordination with equipment belonging to the interfered cell.
