Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme of the embodiment of the invention is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, all other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belong to the scope of protection of the invention.
For a better understanding of the present invention, at first the relational language among the present invention is described.
In embodiments of the present invention, " Serving cell " refers to the current residential quarter that communicates with UE." non-service cell " refers to the current residential quarter that does not communicate with UE.
" with frequently " in the embodiment of the invention refers to the employed frequency of the current communication of UE." alien frequencies " refers to any other frequency except the employed frequency of the current communication of UE.
The embodiment of the invention provides a kind of method of measurement, and as shown in Figure 1, based on eNB (evolved Node B, evolved base station), described method comprises:
11, send to measure configuration signal to UE, described measurement configuration signal includes and reports indication information, the described mode that reports that reports channel quality measurements that indication information is used to indicate described UE.
Wherein, described eNB can be to UE configurating channel quality gate limit value, and when the channel quality of described UE and its Serving cell was lower than described channel quality thresholds value, described UE started corresponding channel quality measurement according to the described measurement configuration signal that receives.Alternatively, Serving cell is the Serving cell under the carrier aggregation scene.
Alternatively, the trigger mechanism that the configurable UE of described eNB reports, for example, described UE according to the channel quality measurements that reports mode to report greater than certain threshold value, perhaps less than certain threshold value, perhaps compare with other channel quality measurements when there are differences and (for example than the deviant of the high appointment of other channel quality measurements, perhaps hang down the deviant of appointment than other channel quality measurements), trigger UE according to reporting mode reporting measurement result.
In embodiments of the present invention, described measurement configuration signal specifically can be RRC (radio resource control, Radio Resource control) signaling, MAC (media access control, medium access control) signaling etc.
The mode that reports of described channel quality measurements refers to, reports the channel quality measurements under a certain or some qualifications.The mode that reports of described channel quality measurements can comprise: report and specify frequency domain under the assigned frequency, specify at least one the channel quality measurements among time domain and the designated port three; Or report and specify frequency domain under the designated cell, specify at least one the channel quality measurements among time domain and the designated port three.
Particularly, described reporting specified frequency domain, specified at least one the channel quality measurements among time domain and the designated port three to comprise under the assigned frequency: report alien frequencies to specify frequency domain, specify at least one the channel quality measurements in time domain and the designated port.Described reporting specified frequency domain, specified at least one the channel quality measurements among time domain and the designated port three to comprise under the designated cell: report the alien frequencies designated cell the appointment frequency domain, specify at least one the channel quality measurements among time domain and the designated port three, perhaps report appointment frequency domain with designated cell frequently, specify at least one the channel quality measurements among time domain and the designated port three.In embodiments of the present invention, described designated cell can be the non-service cell under the carrier aggregation scene.
