In mobile communications network; To data speed and coverage rate require increasingly high; Adopt macro base station to provide the method for access can not satisfy the requirement of data rate and coverage rate; Therefore; Be to improve data rate and coverage rate, mainly be at present adopt cell splitting, at hot zones or at some low power base station of indoor deployment (like HeNB (Home enhanced Node Base Station, Home eNodeB), Pico NB (slight grand station), Relay NB (relay base station) etc.); Low power base station is a kind of base station equipment that is applied under family's indoor environment, working environment or other the little overlay environment, and more high data rate, more professional is provided.
Though the introducing of low power base station has improved data rate and coverage rate to a certain extent; But can cause interference in the system with respect to even more serious with layer network; Especially the interference problem on the control channel has become the bottleneck with the work of frequency heterogeneous network, how to guarantee that the receptivity on each channel then becomes problem demanding prompt solution in the heterogeneous network.Can operate as normal for the assurance system, the strategy that adopts some to avoid interference is at present coordinated mutual interference, but the interference that may cause different resource of employing these tactics is uneven, to having very big influence with the measurement mechanism in the layer network; The user possibly adopt different interference average modes to obtain CQI (Channel Quality Indicator; Channel quality information); And disturb being chosen at of average mode to affect AMC (Adaptive Modulation and Coding to a great extent; Adaptive Modulation and Coding) selection, and may cause the user can not pass through existing test case.
To the isomers network system, like Macro system and Femto system, for solving interference problem; The main method that adopts time domain coordination and power control, as adopting the time domain coordinate scheme, restriction is transmitted in the base station in the Macro system on some subframe; To avoid that the base station in the Femto system is produced bigger interference; As shown in Figure 1, in the Macro system, to a certain radio frames; At subframe 0, subframe 2, subframe 4, subframe 6 and subframe 8 (being filled with the part of oblique line among Fig. 1) transmitting data of this radio frames, but there is not transfer of data in subframe 1, subframe 3, subframe 5, subframe 7 and subframe 9 (part that does not have filling among Fig. 1).
At 3GPP (3rd Generation Partnership Project; Third generation partner program) LTE (Long Term Evolution; Long Term Evolution) in the Rel-8 system; CQI is definite according to DLreference subframe (descending reference subframe) in the physical layer definition, and RAN4 has provided the test case that CQI is required.Terminal equipment manufacturer is the requirement that reaches CQI; Mainly be that averaging of interference with a plurality of subframes obtains final interference value; And according to this final interference value calculating CQI; But be to use interference value that equalization obtains or the interference value that uses instantaneous value to obtain to calculate CQI, can only confirm that which kind of mode the user does not also know to take confirm interference value according to the mode of terminal equipment factory settings.
In the LTE of 3GPP Rel-10 system; Because the interference that the community user that is disturbed is received comparatively significantly fluctuation can occur on time domain, and for R10 user, the mode of employing equalization obtains interference value and still obtains interference value through instantaneous mode; The user can not learn; If also adopt the mode like the R8 system to obtain interference value, the CQI or the CSI (Channel StateInformation, channel condition information) that then obtain according to this interference value are inaccurate.
