- Figure 1 is a schematic diagram of a heterogeneous network architecture. As shown in FIG. 1, the network includes a macro base station 11 and a micro base station.
- the range 13 is the coverage of the macro base station 11
- the range 14 is the coverage of the micro base station 12
- the UE 15 is located in the range 13 and accesses the macro base station 11
- the UE16 and the UE 17 are located in the range 14 and access to the micro base station 12.
- the macro base station 11 and the micro base station 12 may be base stations belonging to different operators, and the frequency bands of the macro base station 11 and the micro base station 12 are adjacent. Of course, the macro base station 11 and the micro base station 12 may also be base stations of the same carrier.
- the UE 15 is close to the UE 16 , and the UE 15 is far away from the UE 17 . Therefore, the uplink signal of the UE 15 reaches the UE 16 with a small path loss, and the uplink signal of the UE 15 reaches the UE 17 with a large path loss, that is, the signal of the UE 15 reaches the UE 16 when the uplink signal reaches the UE 16 . Smaller and stronger.
- the adjacent frequency leakage of the UE 15 may cause interference to the frequency band in which the UE 16 receives the downlink data.
- FIG. 2 is a schematic diagram of adjacent frequency interference in the network shown in FIG. 1.

- UE 15 may cause interference to UE 16 and UE 17, but it can be seen from curve 24 that the interference generated by UE 15 to UE 17 does not exceed the interference tolerance threshold of UE 17, and therefore the uplink transmission of UE 15 does not downlink to UE 17.

- the UE 16 When the UE 16 is interfered by the UE 15, the UE 16 needs to measure the channel quality and report the CSI to the micro base station 12. However, in the current three CSI measurement and reporting schemes, if a broadband CSI side is used In this case, since the UE 16 is only interfered in the frequency band in the area 26, and the wideband CSI reflects the channel quality of the entire downlink frequency band in the area 22, the wideband CSI scheme may be used to report the full-band average CSI to the micro base station 12. , can not reflect the interference situation of UE16.
