Embodiment
For considering with the compatibility of conventional single-antenna UE, the UE (usually having two antennas) that is using many antennas is to the measurement result of base station controller reporting measurement cell signal quality the time, can consider that the cell signal quality that a plurality of antenna measurements are obtained asks for linear average, the mean value of trying to achieve is reported base station controller, make base station controller carry out RRM according to the measurement result that many antennas UE reports.
but so just there is a problem to exist, here illustrate as example with the UE that uses double antenna: as same geographical position, single antenna UE reporting measurement is A as a result, if and the cell signal that double antenna UE has an antenna measurement to obtain is second-rate, report based on the linear average of asking for the measurement result that two antenna measurements obtain, the measurement result B that reports will be less than A, and in fact double antenna UE in same geographical position, its measurement result should be only greatly than the measurement result that single antenna UE measures reasonably, therefore as seen only report based on the linear average of asking for the measurement result that each antenna measurement obtains, will inevitably exist reported result to have the problem of error, and then the measurement result that makes base station controller report according to many antennas UE is when carrying out RRM, the phenomenon of error may appear managing.
When for example the measurement result that only reports according to the UE that is using double antenna of base station controller is carried out RRM, may produce following point:
When controlling UE and carrying out soft handover: the small active area collection signal quality deviation that reports due to UE, therefore base station controller is more prone to set up more Radio Link to UE, and in fact the quality of reception of UE is so not poor, this has just caused the waste of Internet resources, directly causes the network downlink capacity to dwindle.
When controlling UE and carrying out direct-cut operation: the Target cell signal quality deviation that reports due to UE, so base station controller can postpone and carry out direct-cut operation, causes direct-cut operation untimely, cutting off rate rises.
When UE is carried out open loop power control: the cell signal mass deviation that reports due to UE, so base station controller will estimate path loss bigger than normally, and the Initial Trans value of setting is bigger than normal, thereby causes the descending power waste, and the network downlink capacity dwindles.
For these reasons, the embodiment of the present invention 1 proposes a kind of radio resource management method on the basis of such scheme, and the specific implementation process can be as follows:
Base station controller receives cell signal that the UE using many antennas reports quality first measurement result, and this first measurement result is that cell signal quality that UE obtains each antenna measurement is carried out to merge to process and obtained; Base station controller carries out various RRMs according to the first measurement result that receives.
Wherein, merging processing can be that maximum rate merges processing or the selectivity merging is processed.
In addition, UE can also ask for the cell signal quality that each antenna measurement is obtained cell signal quality the second measurement result that linear average obtains and report base station controller, to adapt with existing standard.
As shown in Figure 1A, take terminal with double antenna ability as example, the flow process of such scheme can be as follows:
Step 11, judge that whether terminal is using double antenna, if so, carry out step 12; Otherwise, carry out step 13.
The cell signal quality that step 12, terminal to report obtain two antenna measurements is carried out to merge and is processed the double antenna measurement result that obtains, and then carry out step 14.
In addition, in order to adapt to existing standard, terminal can also be asked for linear average with the cell signal quality that two antenna measurements are obtained, and resulting mean value is reported base station controller.
Wherein, the cell signal quality that obtains of antenna measurement can characterize based on signal strength signal intensity or signal to noise ratio (Ec/No).When with noise recently during the characterization signal quality, after the signal to noise ratio that two antenna measurements obtain merged according to maximum rate, resulting double antenna signal to noise ratio equaled the linear sum of the signal to noise ratio that two antennas measure respectively.Selectivity merges processing and refers to select a signal quality preferably as the double antenna measurement result in the signal quality that two antenna measurements obtain.For example, if the cell signal signal to noise ratio that two antenna measurements obtain is respectively A and B, A＞B wherein, adopt and ask for the measurement result that linear average obtains and be (A+B)/2, adopting maximum rate to merge and processing the double antenna measurement result that obtains is A+B, and adopting selectivity to merge and processing the double antenna measurement result that obtains is A.
Generally adopt merging to process the signal quality measurement result that obtains and to ask for higher than employing the measurement result that linear average obtains.
If step 13 terminal is using single antenna to receive, perhaps there is an antenna channels to damage in double antenna, can't use double antenna to receive, then the cell signal quality measured result that only reports single antenna to measure carry out step 14.
Whether step 14, base station controller receive the measurement result that UE reports, judge to comprise in this measurement result to adopt to merge to process the double antenna measurement result that obtains, and if so, carry out steps 15; Otherwise, carry out step 16.
The double antenna measurement result that step 15, base station controller preferentially use the merging processing to obtain is carried out RRM.
Radio resource management method is same as the prior art, does not make change.
Radio resource management method is same as the prior art, does not make change.
In such scheme, merge to process the double antenna measurement result that obtains and carry out RRM because base station controller preferentially uses, so terminal also can not send the linear value that cell signal quality that two antenna measurements are obtained is asked for.
Below only take double antenna as example, for other terminals with more antennas, such scheme stands good.

In addition, this base station controller also comprises the second receiving element 103, be used for to receive cell signal quality the second measurement result that UE reports, and this second measurement result is the linear average that cell signal quality that UE obtains each antenna measurement is asked for.
Because preferential the first measurement result of using the first receiving elements 101 to receive of radio resource managing unit 102 is carried out RRM, so this base station controller also can not receive to adopt and asks for the second measurement result that linear average obtains.
