Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
The testing scheme that moves in the minizone from existing test UE, Center for architecture is RSRP or the RSRQ that controls UE, is except controlling these two parameter values by artificial adjusting adjustable attenuator, the method that has other or not controlled RSRP or the RSRQ of UE so?
Answer has.It is cell reference signals power (RsPower) that individual parameter is arranged in the LTE cell parameter, the implication of cell reference signals power is the EPRE(Energy Per Resource Element on the public reference signal single port of residential quarter, be the transmitting power on single sub-carrier), span is-60 to 50dBm, affects residential quarter covering, down-run survey, descending power distribution etc.This parameter is by the configuration of the referenceSignalPower IE in the PDSCH-ConfigCommon in the SystemInformationBlockType2 signaling of 3GPP36.331 regulation, and parameter corresponding in 3GPP36.213 is cell-specific RS EPRE.This parameter has realized and can dynamically adjust by the BTS management station at present, when this parameter value changes, the down transmitting power of residential quarter also changes thereupon, therefore RSRP or the RSRQ of this residential quarter UE also can change, the reference signal power of the residential quarter amplitude (db) that increases or reduce in theory, the amplitude that increases or reduce with the RSRP of UE is consistent.And the base station can be notified the referenceSignalPower parameter value to UE by the SystemInformation signaling, so that UE uses this calculation of parameter path loss, determines the transmitted power of upward signal.
From above analysis, by adjusting the cell reference signals power of residential quarter, just can adjust RSRP or the RSRQ of UE, thereby make the RSRP of UE or the condition that RSRQ satisfies cell reselection or switching, trigger UE and carry out minizone gravity treatment or switching.Below divide embodiment that the present invention program is described in detail.
