Specific embodiment
With reference to the accompanying drawing, further description of the specific embodiments of the present invention.Following embodiment is only used for more
Technical solution of the present invention is clearly demonstrated, and not intended to limit the protection scope of the present invention.
Fig. 3 shows a kind of flow diagram of reference information interference processing method provided in this embodiment, comprising:
S301, the second base station receive the reference signal configuration information that first base station is sent.
Wherein, the first base station (gNB1 in corresponding diagram 1) and second base station (gNB2 in corresponding diagram 1) are phases
Two adjacent base stations obtain reference information interference when first base station is measured by corresponding first terminal (UE1 in corresponding diagram 1)
After measurement result, when knowing reference information interference according to the judgement of reference information interference measurement results, by the ginseng of the first terminal
It examines signal configuration information and is sent to second base station.
The reference signal configuration information is the configuration information of the reference signal of first terminal, by by the reference signal
Configuration information is sent to the second base station, so that the corresponding second terminal in the second base station (UE2 in corresponding diagram 1) and described first is eventually

Reference signal) or DMRS (demodulated reference signal), i.e., the present embodiment is suitable for the dry of the reference signals such as CSI-RS, SRS or DMRS
Disturb problem.
S302, set pre- for the default position of DCI (downlink physical control channel) according to the reference signal configuration information
If value.
Wherein, the DCI is the downlink physical control channel of second base station, includes several data in the DCI
Position.
The default position is the data bit in pre-set DCI, whether there is reference signal-to-interference problem for recording.
The preset value is pre-set value, and expression has reference signal-to-interference.For example, when preset value is
When 1, there is reference signal-to-interference in expression, when preset value is 0, indicate that reference signal-to-interference problem is not present.
S303, when second base station is scheduled second terminal, if judging to know that the default position is described pre-
If value, then data transmission and reception are carried out using the first default mechanism, otherwise using the second default mechanism carry out data send and
It receives.

Amount result is fed back to first base station (gNB1), and first base station is known according to the judgement of reference information interference measurement results in the presence of with reference to letter
Interference problem is ceased, then obtains the reference signal configuration information of first terminal, and reference signal configuration information is sent to the second base
Stand (gNB2), and the second base station receives and sets 1 for the default position of DCI after the reference signal configuration information.Work as first terminal
(UE1) it needs to be communicated with second terminal (UE2), the second base station is being scheduled to realize first terminal and second terminal
When communication, if judgement knows that the default position of DCI is set as 1, data transmission is carried out using the code division multiplexing mechanism of default setting
And reception carries out data transmission and reception using existing default mechanism, keeps away if judgement knows that the default position of DCI is set as 0
Exempt from the reference signal-to-interference problem between base station.Referring to fig. 4, base station can pass through the NR of adjacent area in the resource location of regulation mechanism
CSI-RS carries out reference information interference measurement.Specifically, first base station carries out the reference information of CSI-RS to uplink signal (UL)
After interference measurement, can the coordination resource location of downlink signal (DL) to the second base station be updated, the NR transmitted according to adjacent area
The NR CSI-RS configuration information is allocated to corresponding second terminal by high-level signaling by CSI-RS reference signal configuration information.
When terminal room is there are when reference signal-to-interference, referring to fig. 2 and Fig. 5 using above-mentioned same way avoids terminal room
Reference signal-to-interference problem.
The present embodiment is by being arranged default position in downlink physical control channel, by judging that it is corresponding that different preset values determine
Data transmission and reception mechanism effectively reduces interference suffered by reference signal, improves the Receiver Precision of reference signal, can be into one
Channel state information is effectively estimated in step, improves decoding efficiency.
