Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
The testing scheme of UE in minizone movement is tested from existing, Center for architecture is RSRP or RSRQ of control UE, so except by artificially regulating adjustable attenuator to control, except these two parameter values, to have other method or not to RSRP or RSRQ of control UE?
Answer has.Individual parameter is had to be cell reference signals power (RsPower) in LTE cell parameter, the implication of cell reference signals power is the EPRE(Energy Per Resource Element in cell common reference signal single port, namely the transmitting power on single sub-carrier), span is-60 to 50dBm, affects MPS process, down-run survey, descending power distribution etc.ReferenceSignalPower IE in PDSCH-ConfigCommon in the SystemInformationBlockType2 signaling that this parameter is specified by 3GPP36.331 configures, and parameter corresponding in 3GPP36.213 is cell-specific RS EPRE.This parameter has realized to carry out dynamic conditioning by Base Station Management station at present, when this parameter value changes, the down transmitting power of community also changes thereupon, therefore RSRP or RSRQ of this community UE also can change, the reference signal power increase of community or the amplitude (db) of minimizing, consistent with the amplitude that the RSRP of UE increases or reduces in theory.And referenceSignalPower parameter value can be informed to UE by SystemInformation signaling by base station, so that UE uses this calculation of parameter path loss, determine the transmitted power of upward signal.
Analyze from above, by adjusting the cell reference signals power of community, just can adjust RSRP or RSRQ of UE, thus making RSRP or RSRQ of UE meet the condition of cell reselection or switching, trigger UE and carry out minizone gravity treatment or switching.Below a point embodiment describes in detail the present invention program.
